Edit
This entry is adapted from the peer-reviewed paper 10.3390/nu15183984

Breast cancer (BC) is a lethal malignancy with high morbidity and mortality but lacks effective treatments thus far. Histone deacetylases 2 (HDAC2) inhibitor (HDAC2i) has been proven to exhibit an anti-cancer effect, can act as a sensitizer for immune checkpoint inhibitors (ICIs) therapy. Simultaneously, dietary intervention, as a crucial supportive therapy, has been reported to provide ingredients containing HDAC2 inhibitory activity. Thus, the novel integration of dietary intervention with ICIs therapy may offer promising possibilities for improving treatment outcomes.

1. Introduction

Breast cancer is one of the most common malignancies in women worldwide, which can occur in both men and women, and ranks as the second cancer-related cause of death worldwide [1][2]. Its development has been reported to be significantly associated with dietary habits (such as alcohol consumption, high intake of total fat, and low consumption of dietary fiber, etc.) [3]. Five molecular subtypes are classified based on the expression levels of the estrogen receptor (ER), progestogen receptor (PR), human epidermal growth factor receptor 2 (HER2) and Ki-67: Luminal A (ER positive and/or PR positive, HER2 negative, Ki-67 < 20%); Luminal B (HER2 negative/B1: ER positive and/or PR < 20%, HER2 negative, Ki-67 ≥ 20%; HER2 positive/B2: ER positive and/or PR positive, HER2 overexpression); HER2 positive type (HER2 positive, ER negative, PR negative); triple-negative (HER2 negative, ER negative, and PR negative) (TNBC); and other special types [1][2]. The recurrence and/or metastasis of breast cancer significantly contributes to breast cancer-specific mortality, as recurrent tumors tend to be more aggressive and often show resistance to currently available treatments [4]. Thus, to improve treatment outcomes, including overall survival (OS) and disease control, endocrine-, chemo-, targeted- and immuno-therapy alone or in combination have been studied extensively [5]. Immune checkpoint inhibitors (ICIs), which reactivate exhausted CD8+ T cells to kill tumor cells [6], have especially made significant progress in the clinical application of breast cancer treatment [5]. However, the benefit population of breast cancer from ICI monotherapy is limited, making the combined regimen a new research hotspot [5].
The usage of ICIs is to harness the body’s immune system to recognize and attack cancer cells more effectively. For instance, by blocking the interaction between immune checkpoints, such as programmed cell death protein 1 (PD-1) and its ligand (PD-L1), the “brakes” on the immune system could be released, allowing immune effector cells to recognize and attack cancer cells more effectively [5]. Fortunately, ICIs have demonstrated a certain efficacy in combination with chemotherapy in the treatment of both early- and late-stage triple-negative breast cancer (TNBC) [7]. The KEYNOTE-355 trial evaluated the efficacy of PD-1 antibody pembrolizumab in combination with chemotherapy for patients with metastatic TNBC. In the context of early-stage disease, the KEYNOTE-522 study demonstrated significant benefits by adding pembrolizumab to chemotherapy, irrespective of the PD-L1 status [7][8][9].
Despite these advancements, there are still important unresolved issues. For instance, determining the optimal partners for ICIs to mitigate ICI side effects, and predictive biomarkers to identify who benefit from ICI therapy [7][10]. Another issue that cannot be ignored is that ICIs caused loss of appetite, consequently reducing the patient’s nutritional intake [11], and aggravating the patient’s already damaged physique and immunity, forming a vicious circle.
Histone deacetylases 2 (HDAC2), as a member of HDACs, is a special protease involved in the tightening of the chromatin structure and suppression of gene transcription. Its expression level was significantly in positive correlation with the poor overall survival of patients with BC or hepatocellular carcinoma (HCC) and with the potential adverse effect of patients to PD-1 antibody therapy [12][13][14][15]. Moreover, breast cancer tissues show significantly higher HDAC2 expression than normal breast tissue [13][14][15]. HDAC2 inhibition is a potential anti-cancer agent against breast cancer [16][17][18]. HDAC2 inhibitors can exert a synergistic effect with ICIs [18][19]. Given that short-chain fatty acids (SCFA, e.g., butyric acid) are the fermentation products of dietary fibers, dietary intervention may provide a superior safety profile improving immunotherapy by functioning as HDAC2i [20].

2. Dietary HDAC2i in Breast Cancer 

2.1. HDAC2: A Potential Index of Aggressiveness and a Therapeutic Target against BC

HDAC2 is an enzyme involved in the tightening of the chromatin structure and suppression of gene transcription. Evidence has indicated that HDAC2 is overexpressed in breast cancer cells compared to normal breast tissue. Higher levels of HDAC2 have also been associated with more aggressive tumor characteristics, such as increased cell proliferation, invasion, and metastasis [12][13][14][15]. For instance, a clinical study that included 226 BC patients reported that expression of HDAC2 protein is significantly higher in breast cancer than in benign tumors and indicates that HDAC2 may be involved in invasion, metastasis, anthracyclines therapy resistance, and poor prognosis of sporadic breast cancer.

2.2. HDAC2 Inhibition for Treating Breast Cancer

HDAC2 has been identified as a crucial regulator of epigenetic control in BC and HDAC2 suppression has been further proved to be an effective approach to treating BC by numerous studies [21][22][23]. For instance, HDAC2 inhibition has been observed to inhibit cellular proliferation in a p53-dependent manner in BC cells [24]. MiR-155 can also decrease the expression of erythroblastic oncogene B by targeting HDAC2 [25]. Moreover, evidence has indicated that PELP1 (proline, glutamate, and leucine-rich protein 1) can bind to miR-200a and miR-141 promoter sequences and modulate the expression of these miRNAs by recruiting HDAC2; therefore, regulating tumorigenic and metastatic potential of BC cells [26]. Thus, a molecular network involving HDAC2 has been considered to serve as a target for developing anti-cancer drugs [26].
Inhibition of HDAC2 has also been found to exert a synergistic effect in BC treatment. For instance, evidence indicates that depleting HDAC2 can sensitize breast cancer cells to apoptosis induced by epirubicin. This finding highlighted the potential of HDAC2 as a therapeutic target and a biomarker in treating breast cancer [27]. Moreover, the modulation of estrogen receptor (ER) signaling is a promising therapeutic approach in ER-expressing breast cancers, and the progesterone receptor (PR) also plays a critical role in this process [28]. 

2.3. HDAC2 Inhibition Enhances the Therapeutic Effect of ICIs in BC Treatment

The emergence of immune checkpoint inhibitors (ICI) has revolutionized the treatment of breast cancer [29][30][31][32][33][34][35][36]. Adjuvant or neoadjuvant immune checkpoint blockades are used for metastatic breast cancer [30]. Despite ICI therapy being promising, breast cancer cells often find ways to evade the host’s immune system, necessitating combination therapies to overcome these limitations. HDAC inhibitors (HDACi) have demonstrated potent immunomodulatory activity, making them a rational choice for cancer immunotherapies.

2.3.1. HDAC2 Regulates PD-L1 Nuclear Translocation

As a ligand of PD-1, high PD-L1 levels indicate tumor progression and are associated with poor prognosis in immunotherapy-treated human cancer [31]. PD-L1 nuclear translocation has been identified as a key mechanism underlying the immune evasion of BC cells, hindering PD-1 inhibitors [32]. Both cytoplasmic and nuclear PD-L1 can exert immunosuppressive functions on BC cells [33]. Nuclear PD-L1 has been linked to various cellular processes, for example, increasing the anti-apoptotic capacity of tumor cells, promoting mTOR activity, and upregulating glycolytic metabolism [32]. A study has shown that the level of nuclear PD-L1 expression was positively correlated with immune response-related transcription factors, such as STAT3, RelA (p65), and c-Jun [19]. Nuclear PD-L1 interacts with transcription factors, such as RelA and the IFN regulatory factor (IRF), influencing antitumor immunity. Inhibition of nuclear PD-L1 expression led to downregulation of genes involved in evading immune surveillance, such as PDCD1LG2 (encoding PD-L2), VSIR (encoding VISTA), and CD276 (encoding B7-H3), which enhance cytotoxic T-lymphocyte depletion and promote tumor aggressiveness, distant metastasis, and resistance to PD-L1/PD-1 blockade therapy [18][19][34] (Figure 1).

HDAC2i suppresses IFNγ-induced PD-L1 expression regulated by HDAC2, therefore decreasing the immune escape of BC cells mediated by PD-L1. In addition, HDAC2i inhibits the process of PD-L1 nuclear translocation regulated by HDAC2/HIP1R axis, hence enhancing the therapeutic effect of PD-1 blockade treatment.

2.3.2. HDAC2 Regulates IFN-γ- Induced PD-L1 Expression

IFN-γ upregulates the expression of PD-L1
Interferon-γ (IFN-γ) is a crucial cytokine in both innate and adaptive immunity and should be considered as an important driving force for PD-L1 expression in tumor microenvironment. It is able to induce PD-L1 expression on BC cells and increase the apoptosis of antigen-specific T cells, such a process is referred to as “adaptive resistance” [37]. Depleting IFN-γ receptor 1 has been reported to decrease the expression of PD-L1 expression in BC cells, increase the amount of tumor-infiltrating CD8+ lymphocytes or CTLs, and to inhibit the development of BC cells [38].
HDAC2i affects IFN-γ induced PD-L1
HDAC2 can promote PD-L1 induced via IFN-γ stimulation in BC cells [18][19]. Specifically, IFN-γ can induce gene transcription involving STAT1 binding to the gamma interferon activation site (GAS), recruiting HAT and HDAC for chromatin remodeling [39]. Following IFN-γ stimulation, BRD4 is rapidly recruited to the PD-L1 locus, accompanied by increased H3K27ac and RNA Polymerase II (RNA Pol II) occupancy in cancer cells [39]. A ChIP-qPCR assay confirmed enhanced HDAC2 binding to the PD-L1 promoter after IFN-γ treatment. HDAC2 knockout led to reduced STAT1 occupancy and bromodomain-containing 4 (BRD4) recruitment to the PD-L1 promoter, attenuated H3K27ac and H3K9ac (markers of active transcription in the PD-L1 promoter) upregulation induced by IFN-γ, highlighting HDAC2’s role in activating PD-L1 expression through IFN-γ induced signaling pathways [18]. 

2.4. Dietary Intervention Is Important for Breast Cancer Patients Receiving Anti-Cancer Immunotherapy

A healthy diet rich in vitamins, minerals, antioxidants, and phytochemicals, provides essential ingredients for building and strengthening a healthy immune system. Thus, the American Cancer Society (ACS) releases the Nutrition and Physical Activity Guideline for Cancer Survivors, which enhances immune function by supporting essential nutrients [40][41][42][43], helping to optimize the effectiveness of immunotherapy and improve treatment outcomes. Moreover, anti-cancer immunotherapy also possesses toxicities and can lead to various adverse effects on breast cancer patients, such as fatigue, nausea, loss of appetite, and gastrointestinal issues [44]. However, proper dietary interventions have been found to help alleviate these side effects by providing proper nutrition, promoting hydration, and supporting gastrointestinal health [45][46][47].

2.5. Dietary HDAC2i

Compared to commonly used anti-cancer therapies, dietary interventions are safer and more cost-effective [48][49]. Even if dietary interventions cannot be considered a replacement for conventional cancer treatments, their role in improving the outcomes of cancer treatment also cannot be ignored [50][51] (Figure 2).
Nutrients 15 03984 g003
Figure 2. Potential advantages of applying proper dietary intervention in BC patients who receive ICIs treatment.
One advantage of dietary intervention is the minimal side effects compared to anti-cancer therapies [52][53]. Immunotherapy, chemotherapy, and radiation therapy can often cause adverse reactions such as fatigue, arthralgia, rash, pruritus, pneumonitis, acute kidney injury, and also a weakened immune system [54][55][56][57]. In contrast, dietary changes usually focus on incorporating natural, nutrient-rich foods, which are less likely to cause significant side effects [53].
Anti-cancer therapies often involve powerful and aggressive drugs that can be toxic to healthy and normal cells in the human body [58]. Such toxicity can lead to additional health complications and adversely affect a patient’s well-being [58]. Dietary interventions, on the other hand, prioritize whole foods, fruits, vegetables, and other plant-based sources that provide essential nutrients without the toxic effects associated with some medical treatments [59].
Cancer patients who undergo multiple treatments or take various medications simultaneously will face the increased risk of adverse effects due to drug interactions or unwanted chiral compounds [60]. Dietary interventions generally use natural foods rather than pharmacological compounds, which have both left- and right-hand chiral compounds in balance [61].
Dietary interventions can be customized to suit each individual’s needs and medical conditions [62]. This adaptability allows dietary plans to be tailored based on any pre-existing conditions, allergies, or specific dietary restrictions of each patient, ensuring a safer approach [62].
As a long-term lifestyle change, dietary interventions offer the advantage of being sustainable even after the initial treatment period. This sustainable approach helps maintain the patient’s overall health and reduces the risk of developing long-term side effects associated with certain anti-cancer therapies [63].
Dietary interventions can complement anti-cancer therapies by providing a supportive role [61]. A healthy diet can help strengthen the immune system, improve overall health, and enhance the body’s ability to cope with cancer treatments.
Certain dietary strategies, such as adopting a balanced and nutrient-rich diet, regular physical activity, and weight management, have the potential to reduce the risk of developing cancer [51][64][65][66][67][68]. Prevention is a crucial aspect of cancer management, and dietary interventions can also play a significant role in reducing the occurrence of cancer [61].

2.6. Selected Candidates of HDAC2i

2.6.1. Genistein (GE)

GE is the most predominant bioactive isoflavone found mainly in soybean products and other food sources such as lupin, fava beans, kudzu, and psoralea [68]. GE has been reported to act as a potent chemo-preventive and therapeutic agent against various types of cancers including breast, prostate, and lung cancer [69]. For instance, GE suppresses the growth of BC cells in patient-derived tumor xenograft (PDX) [69]. Moreover, GE has been reported to modify the expression levels and activities of key epigenetic-associated genes, including HDAC2, DNA methyltransferases (DNMT3b) and ten-eleven translocation (TET3) methylcytosine dioxygenases. These genes are involved in epigenetic modifications, such as DNA methylation and histone methylation, which can regulate gene expression and impact cellular behavior [69]. By modulating the activities of these epigenetic regulators, GE may influence the epigenetic landscape of breast cancer cells, leading to changes in gene expression patterns that can affect cancer-related pathways.

2.6.2. Sulforaphane (SFN)

SFN is a natural compound and is abundant in cruciferous vegetables such as broccoli sprouts (BSp) and kale [70]. It has gained attention for its potential health benefits, including its ability to inhibit HDAC2 activity [71][72]. In the context of breast cancer, a dietary regimen of genistein and BSp in combination has been shown effective in reducing mammary tumor incidence and delaying tumor latency in a spontaneous breast cancer mouse model [73]. The combination of GE and SFN downregulated HDAC2 protein levels in breast cancer cells.

2.6.3. Chrysin and Its Analogues

Chrysin and its analogues are a group of polyphenolic compounds found in various dietary sources such as fruits, vegetables, olive oil, tea, and red wine [74]. The cytotoxic effects of chrysin have been shown against a wide range of cancer cell lines, including BC (MCF-7, MDA-MB-231), colon cancer (Lovo, DLD-1), and prostate cancer cells [75][76]. It is able to induce G1 cell cycle arrest and inhibit the activity of HDACs, specifically HDAC2 [77].

2.6.4. Resveratrol (RSV)

RSV is also a polyphenol abundant in grape skin and seeds. It also presents in other food sources such as apples, blueberries, mulberries, peanuts, pistachios, plums, and red wine [78]. RSV has numerous beneficial properties of anti-glycosylation, anti-inflammation, anti-neurodegeneration, and antioxidation in various types of cancer [79]. One intriguing aspect of RSV is its proposed potential as a pan-HDAC inhibitor [80].

2.6.5. Oleuropein (OLE)

OLE is a polyphenolic compound in virgin olive oil with antineoplastic properties and it is well tolerated by humans [81]. Studies have shown that OLE can reduce progression, invasion, and proliferation of breast cancer cells by suppressing the activity of both HDAC2 and HDAC3 [82]. However, OLE exhibits little negative effect on normal breast epithelial cells, suggesting a potential selectivity towards BC cells and its potential for BC patients receiving ICIs therapy [82].

2.6.6. Curcumin

Curcumin, a lipophilic polyphenol derived from turmeric (Curcuma longa), has been extensively studied for its diverse health-promoting properties, including antioxidant, anti-inflammatory, hepatoprotective, anti-atherosclerotic, and antidiabetic effects [83].

2.6.7. Valeric Acid

Valerian (Valeriana officinalis) is a medicated diet that has been commonly used in cooking soup by some ethnic minorities in China for hundreds of years for restoring and balancing body energy [84]. Valeric acid, a major active component of valerian, has been identified as a potential HDAC inhibitor with anti-cancer effects on liver and breast cancer [84].

2.6.8. Rh4

Ginseng is also a typical medicated diet item and is commonly used for making cuisine mainly in Asia. It is also a traditional Chinese herb with multiple biological effects. One of its components, Rh4, has been identified as a rare ginsenoside with potential inhibitive effects on the development of various cancers [85]. Rh4 can inhibit the expression of PD-L1 by regulating HDAC2-mediated JAK/STAT in breast cancer cells [86].

2.6.9. Butyrate (NaB)

NaB, a short-chain fatty acid generated via the fermentation of dietary fiber by the colonic microbiota, has shown anticancer activities mediated through HDACi [87]. NaB is primarily derived from undigested dietary carbohydrates, such as resistant starch and dietary fiber and, to a lesser extent, from dietary and endogenous proteins [88][89]. Studies have demonstrated that treatment with NaB, when combined with retinoids, enhances the inhibition of breast cancer cell proliferation [90].

2.6.10. Other Potential Candidates

Some other dietary compounds have also been identified as HDAC2i in other cancer types. For instance, green tea and its bioactive components, especially polyphenols, possess many health-promoting and disease-preventing benefits with anti-inflammatory, antimutagenic, antioxidant, and anticancer properties, but have no significant toxicity on normal cells in vivo. It has the potential as an effective chemotherapeutic agent for cancer prevention and treatment through various cellular, molecular, and biochemical mechanisms [91]. The major polyphenol components of green tea are (-)-epigallocatechin-3-gallate (EGCG), (-)-epigallocatechin (EGC), (-)-epicatechin-3-gallate (ECG) and (-)-epicatechin (EC) [91]. One of the molecular mechanisms underlying the anticancer effects of green tea polyphenols (GTPs) is HDAC2 inhibition [92].

2.7. Potential Approaches of Taking Bioactive Compound

For enhancing absorption efficiency and therefore improving the potential health benefits and biological activities of certain bioactive compounds, many means of application have been developed [93]. Some of them might provide a better way for BC patients receiving ICIs to gain HDAC2i efficiently. However, it is important to emphasize that thorough exploration in this area is still a pressing necessity.
Nutraceuticals and Dietary Supplements
Many bioactive compounds with antioxidant or anti-inflammatory properties, found in certain fruits or vegetables, have been produced as nutraceuticals and dietary supplements for taking them more conveniently and easily [48]. Moreover, nutraceuticals and dietary supplements have been found to maintain excellent safety levels [94].
Nanotechnology and Drug Delivery
Bioactive compounds can also be incorporated into well-designed nanoparticles for targeted drug delivery, enhancing drug efficacy and reducing side effects [95]. For instance, theracurmin, a curcumin formulation consisting of dispersed curcumin with colloidal nanoparticles, possesses significantly improved bioavailability and therapeutic efficacy for treating osteoarthritis, compared to turmeric powder monotherapy [96][97][98].
Pharmaceuticals and Medicinal Products
Some bioactive compounds can be isolated and developed into pharmaceutical drugs to efficiently improve their therapeutic effect [99]. For instance, curcumin, a bioactive compound that has been found to possess multiple biological regulatory functions, has been successfully isolated from plant curcuma aromatica salisb for treating different types of cancer, including BC [100][101].
Phytotherapy and Traditional Medicine
Phytotherapy and traditional medicine have been widely applied in treating various of diseases [102][103]. They are natural, with relatively low irritation and side effects on the human body, and can also be utilized in combination with other treatment [104][105].

2.8. Nutrients That May Impair the Therapeutic Effect of ICIs

Omega-3 Fatty Acids
Omega-3 fatty acids, commonly present in fish oil and certain plant sources, possess anti-inflammatory properties and are essential for synthesizing hormones and endogenous substances [106]. Natural killer (NK) cells are innate lymphocytes responsible for orchestrating immune responses against tumors and viruses [107]. Fish oil supplementation was found to decrease NK cell activity, which rebounded after supplementation ceased [108].
Vitamins
Vitamins are a type of trace organic substance obtained from food that can maintain normal physiological functions in humans [109]. Vitamins participate in the biochemical reactions of the human body and regulate metabolic functions, including immunity [110]. Deficiency or over intake of certain vitamins has been found to impair anti-cancer immunity, therefore affecting the efficiency of ICIs [111]. 
Probiotics
Probiotics, including bacteria and yeast, are living microorganisms [112][113]. Some of them have been commonly utilized to promote gut health, closely intertwined with immune function [112][113]. Recent evidence has newly pointed out that an excessive immune response in the gut induced by overconsumption of probiotics might constrain the systemic immune reaction necessary for the optimal efficacy of ICIs [114][115]. 
High-Fiber Diets
Fiber-rich diets primarily comprise two essential elements: soluble fiber and insoluble fiber. These vital components are found in an array of plant-based foods, including legumes, whole grains, cereals, vegetables, fruits, nuts, and seeds. Dietary fiber is composed of non-starch polysaccharides and various plant constituents like cellulose, resistant starch, and resistant dextrins [116]. High-fiber diets have been considered to modulate the gut microbiota and influence immune responses [117]. While a diverse gut microbiome is generally associated with better health, certain bacterial metabolites produced from high-fiber diets could potentially hamper the efficiency of ICIs [118].
Ketogenic diet
The ketogenic diet (KD) is characterized by high fat, low to moderate protein, and very low carbohydrate intake [119]. Evidence has shown that KD can lead to a downregulation of CTLA-4 and PD-1 expression on tumor-infiltrating lymphocytes (TILs), as well as PD-L1 expression on glioblastoma cells in animal models [120]. 
Protein-restricted diet
A low-protein diet serves as a therapeutic approach for managing inherited metabolic disorders like phenylketonuria and homocystinuria. Additionally, it can be employed in the treatment of kidney or liver ailments. Furthermore, a reduced intake of protein has been observed to potentially lower the risk of bone fractures, likely due to alterations in calcium [121].
