Synergistically Anti-Multiple: Flavonoid, Non-Flavonoid Polyphenols, and Bortezomib
Multiple myeloma (MM) is a clonal plasma cell tumor originating from a post-mitotic lymphoid B-cell lineage. When two or more medications are combined to improve their therapeutic effects, this is referred to as drug synergism. For various diseases, including MM, appropriate drug combinations can reduce drug resistance or maximize efficacy. Bortezomib (BTZ), as a clinically used protease inhibitor, is a cornerstone of Velcade, Revlimid, and Dexamethasone (VRD).  Flavonoids and non-flavonoid polyphenols are potential supportive therapies to address some of the challenges faced in BTZ treatment.

Mast Cell Activation
Mast cell activation (MCA) may occur in different physiologic and pathologic conditions. Clinical symptoms resulting from MCA can be observed not only in the setting of allergic diseases, but even in the context of MC neoplasms. If MCA symptoms are severe and recurrent, the possibility of mast cell activation syndrome (MCAS) should be considered.

Protein Lipidation
Proteins play indispensable roles in maintaining cell survival, and their functions are often regulated by post-translational modifications (PTMs), in which proteins are proteolytically cleaved or enzymatically conjugated with modifying groups. Various enzymes, including kinases, phosphatases, transferases, and ligases, catalyze approximately 500 discrete PTMs of a diverse set of proteins. PTMs regulate diverse activities of a colossal number of proteins. For example, various types of lipids can be covalently linked to proteins enzymatically or non-enzymatically. Protein lipidation is perhaps not as extensively studied as protein phosphorylation, ubiquitination, or glycosylation although it is no less significant than these modifications. Evidence suggests that proteins can be attached by at least seven types of lipids, including fatty acids, lipoic acids, isoprenoids, sterols, phospholipids, glycosylphosphatidylinositol anchors, and lipid-derived electrophiles.

Extracellular Vesicles Based Drug Delivery
Extracellular vesicles (EVs) play major roles in intracellular communication and participate in several biological functions in both normal and pathological conditions. Surface modification of EVs via various ligands, such as proteins, peptides, or aptamers, offers great potential as a means to achieve targeted delivery of therapeutic cargo, i.e., in drug delivery systems (DDS). This study summarizes recent studies pertaining to the development of EV-based DDS and its advantages compared to conventional nano drug delivery systems (NDDS).

ICIs for Locally Advanced Resectable ESCC
Esophageal cancer has a high mortality rate and a poor prognosis, with more than one-third of patients receiving a diagnosis of locally advanced cancer. Esophageal squamous cell carcinoma (ESCC) is the dominant histological subtype of esophageal cancer in Asia and Eastern Europe. Although neoadjuvant or definitive chemoradiotherapy (CRT) has been the standard treatment for locally advanced ESCC, patient outcomes remain unsatisfactory, with recurrence rates as high as 30–50%. The combination of immune checkpoint inhibitors (ICIs) and CRT has emerged as a novel strategy to treat esophageal cancer, and it may have a synergistic action and provide greater efficacy.

Tumour Immune Microenvironment
Targeting altered tumour metabolism is an emerging therapeutic strategy for cancer treatment. The metabolic reprogramming that accompanies the development of malignancy creates targetable differences between cancer cells and normal cells, which may be exploited for therapy. In this entry, we focus on the metabolic dysregulation exerted by tumour cells on the immune microenvironment, leading to tumour immunosuppression. This metabolic rewiring and crosstalk with the tumour microenvironment also play a key role in cell proliferation, metastasis, and the development of treatment resistance. Nonetheless, greater understanding of the metabolic crosstalk presents strategies that aid in the precision targeting of altered tumour metabolism, including therapeutic strategies combining metabolic inhibition with immunotherapy.

Integrin α6β4 in Colorectal Cancer
Integrin α6β4 is one of the main laminin receptors and is primarily expressed by epithelial cells as an active component of hemidesmosomes. In this article, after a brief summary about integrins in the gut epithelium in general, I review the knowledge and clinical potential of this receptor in human colorectal cancer (CRC) cells. Most CRC cells overexpress both α6 and β4 subunits, in situ in primary tumours as well as in established CRC cell lines. The mechanisms that lead to overexpression have not yet been elucidated but clearly involve specific transcription factors such as MYC. From a functional point of view, one key element affecting CRC cell behaviour is the relocalization of α6β4 to the actin cytoskeleton, favouring a more migratory and anoikis-resistant phenotype.

ADAR-Mediated Site-Specific RNA Editing in Immune-Related Disease
ADAR (Adenosine Deaminases Acting on RNA) proteins are a group of enzymes that play a vital role in RNA editing by converting adenosine to inosine in RNAs. This process is a frequent post-transcriptional event observed in metazoan transcripts. Recent studies indicate widespread dysregulation of ADAR-mediated RNA editing across many immune-related diseases, such as human cancer.

Cancer Vaccines
Therapeutic cancer vaccines target TAAs alongside adjuvant molecules that can elicit specific antibodies or cytotoxic immune responses against cancer cells. There are different ways to present TAAs to the immune system. DNA and RNA encoding TAAs or whole peptides can be recognized and processed by the APCs; tumor cell lines express TAAs and can chemotactically attract APCs; viral vectors transfect APCs after being loaded with prespecified antigens; finally, DCs act as APCs and can be loaded with TAAs.

Neutrophil Extracellular Traps in Cancer Therapy Resistance
Neutrophils and their products are increasingly recognized to have a key influence on cancer progression and response to therapy. Their involvement has been shown in nearly every aspect of cancer pathophysiology with growing evidence now supporting their role in resistance to a variety of cancer therapies. Recently, the role of neutrophils in cancer progression and therapy resistance has been further complicated with the discovery of neutrophil extracellular traps (NETs). NETs are web-like structures of chromatin decorated with a variety of microbicidal proteins. They are released by neutrophils in a process called NETosis. NET-dependent mechanisms of cancer pathology are beginning to be appreciated, particularly with respect to tumor response to chemo-, immuno-, and radiation therapy.

Flavonoids and Peripheral Neuropathy
Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating condition that severely reduces the quality of life of a considerable proportion of cancer patients. There is no cure for CIPN to date. Here, we explore the potential of flavonoids as pharmacological agents in combating CIPN. Flavonoids alleviate CIPN by reducing oxidative stress, inflammation, and neuronal damage, among other mechanisms.

Target Nanoparticles against Pancreatic Cancer
Pancreatic cancer is the most common lethal tumor in America. This lethality is related to limited treatment options. Conventional treatments involve the non-specific use of chemotherapeutical agents such as 5-FU, capecitabine, gemcitabine, paclitaxel, cisplatin, oxaliplatin, or irinotecan, which produce several side effects. The principal objective of nanoparticles is reduction of the side effects that conventional treatments produce, mostly because of their non-specificity.

The Adaptor Protein p66Shc
p66Shc is an adaptor protein with anti-mitogenic, anti-chemotactic, pro-apoptotic and pro-oxidant activities.  Neoplastic B cells from chronic lymphocytic leukemia (CLL) patients  have a profound deficiency in the expression of p66Shc which results in leukemic cell resistance to apoptosis and in an altered balance between homing and egress receptors that control B cell homing to and residency into the pro-survival lymphoid niche. Ablation of the gene encoding p66Shc in the Eμ-TCL1 mouse model of human CLL worsens disease presentation  by promoting leukemic cell invasiveness, providing in vivo evidence of the pathogenic role of the p66Shc defect in CLL pathogenesis. Here we briefly summarize the functions of p66Shc in lymphocytes, focalizing on the mechanisms exploited by p66Shc to control B cell trafficking and the abnormalities in this process caused by p66Shc deficiency in CLL.

Gastrin/ECL Cells in Gastric Cancer
The enterochromaffin-like (ECL) cell has long been acknowledged to give rise to neuroendocrine tumours (NETs), but not to play any role in carcinogenesis of gastric adenocarcinomas. However, when examining human gastric adenocarcinomas with the best methods presently available (immunohistochemistry with increased sensitivity and in-situ hybridization), it became clear that many of these cancers expressed neuroendocrine markers, suggesting that some of these tumours were of neuroendocrine, and more specifically, ECL cell origin. Furthermore, the carcinogenic effect of Helicobacter pylori is also most probably mediated by gastrin. Thus, the ECL cell and its main regulator, gastrin, are central in human gastric carcinogenesis, which make new possibilities in prevention, prophylaxis, and treatment of this cancer.
