1. Introduction

Lung cancer remains one of the most frequent and deadly types of cancer for both genders, while predictions about the future do not suggest dramatic improvements in incidence and mortality rates [1,2]. There are different histological types of primary lung cancer, classified mainly into non-small-cell lung cancer (NSCLC) and small-cell lung cancer, with an annual incidence of approximately 85% and 15%, respectively. Lung adenocarcinoma (LUAD) is the most common subtype of NSCLC, accounting for around 40% of NSCLC cases [3]. In 2004, the discovery of activating mutations in the gene encoding for epidermal growth factor receptor (EGFR) opened a new era for Lung adenocarcinoma (LUAD) treatment. EGFR mutations occur in nearly 50% of Asian and approximately 15% of Caucasian patients with LUAD [4][1]. Specifically, exon 19 deletions at codons 746–750 and L858R mutation in exon 21 account for approximately 90% of EGFR-sensitizing mutations. Several phase 3 clinical trials have consistently shown the superior efficacy of first-generation (e.g., gefitinib, erlotinib, icotinib) and second-generation (e.g., afatinib) EGFR tyrosine kinase inhibitors (TKIs) in comparison with standard first-line platinum-based chemotherapy in patients with LUAD harboring these EGFR-activating mutations [5,6,7,8,9][2][3][4][5][6]. Despite the robust clinical activity exerted by EGFR TKIs, the majority of patients develop resistance after an average period of 9–15 months. Acquired EGFR-dependent and EGFR-independent genetic alterations are known to be associated with resistance to EGFR TKIs. Among them, the secondary “gatekeeper” mutation EGFR T790M in exon 20 is the dominant resistance mechanism occurring in around 50% of patients treated with first- or second-generation TKIs [10,11][7][8]. Osimertinib is an irreversible third-generation EGFR TKI that is highly selective for both EGFR-activating mutations and the EGFR T790 mutation. In the FLAURA trial, osimertinib resulted in improved survival outcomes compared to first-generation EGFR TKIs, and consequently entered in clinical practice as standard therapy for treatment-naïve patients [12,13][9][10]. Unfortunately, similarly to patients treated with previous-generation EGFR TKIs, patients inevitably develop secondary resistance to osimertinib. In this setting, tertiary acquired mutations such as the EGFR C797S mutation in exon 20 are reported in only 7% of patients treated with first-line osimertinib [14,15][11][12]. In contrast, multiple co-existing molecular alterations such as KRAS mutations, MET amplification, small-cell transformation, and gene fusions have been observed in a considerable percentage of patients [16,17][13][14]. The heterogeneity and coexistence of multiple molecular alterations pose a significant challenge due to the paucity of post-osimertinib pharmacological options and underline the need of new alternative approaches in order to overcome resistance.

2. EGFR-Mutant LUAD Global Metabolic Profile

Physiologically, EGFR activation stimulates different signaling pathways such as PI3K/Akt and MEK/Erk that are tightly linked downstream with the regulation of a highly diverse set of metabolic pathways [22,23,24][15][16][17]. In the context of EGFR-mutant LUAD, the aberrant overactivation of EGFR signaling axis leads to increased glucose uptake, excessive lactate formation, upregulation of the pentose phosphate pathway (PPP), and de novo pyrimidine biosynthesis in EGFR-mutant in vitro models [25][18]. Moreover, the decisive role of EGFR signaling in reprogramming the metabolic landscape of EGFR-mutant LUAD has been demonstrated by treating gefitinib/erlotinib-sensitive (HCC827, PC9) and -resistant (H1975) EGFR-mutant LUAD cells. In particular, the treatment abrogated the activity of crucial metabolic pathways including glycolysis and PPP, downregulating effectively intermediate metabolites such as fructose 1,6-bisphosphate, lactate, and dihydroxyacetone phosphate in EGFR TKI-sensitive cells compared to resistant cells. Interestingly, quantification of these oncometabolites and establishment of cut-offs in the clinic might serve as auxiliary prediction biomarkers to EGFR TKI efficacy in patients with EGFR-mutant LUAD [25][18].

3. EGFR TKI Resistance and Glycolysis/Lactate Metabolism

Glycolysis is a multi-level metabolic process assigned to numerous enzymes. Pyruvate dehydrogenase complex (PDH) is a multienzyme complex that catalyzes the oxidative phosphorylation of pyruvate towards acetyl coenzyme A (Acetyl-CoA). However, phosphorylation of PDH by pyruvate dehydrogenase kinase 1 (PDHK1) inactivates it, resulting in the overproduction of lactate. Interestingly, mRNA levels of PDHK1 along with genes of multiple glycolytic enzymes have been found to be significantly higher in NSCLC compared to normal tissue [26][19]. Today, numerous metabolism-modulating agents are available, and some of them seem to exert an anti-cancer effect.
The tumor microenvironment (TME) is a mixture of active and dynamic components, including a plethora of metabolites that all interact to promote cancer cell survival and proliferation. In particular, the lactate secreted by EGFR TKI-resistant cells is engulfed by cancer-associated fibroblasts (CAFs), triggering the overproduction of hepatocyte growth factor (HGF) and the subsequent activation of MET signaling, suggesting the presence of a non-cell-autonomous metabolism-based mechanism of resistance to EGFR TKIs [28][20]. Erlotinib-resistant in vivo models were generated by subcutaneously injecting the EGFR exon 19 deletion-containing LUAD HCC827 cell line sensitive to EGFR TKIs. Interestingly, derived cell lines from these models were not resistant to erlotinib in vitro. The resistant phenotype was rescued when CAF-enriched conditioned media was cocultured. Importantly, monocarboxylate transporter 4 (MCT4), a lactate transporter and well-known readout of the Warburg effect, was found to be increased in resistant HCC827 cells compared to parental cells, confirming the metabolic rewiring towards aerobic glycolysis. Moreover, stromal HGF and MCT4 were upregulated in NSCLC samples progressed after gefitinib/erlotinib treatment, suggesting potential clinical relevance of the findings. Collectively, the implication of lactate metabolism and MET signaling in EGFR TKI resistance warrants additional research exploring the efficacy of combinatorial treatments with lactate/MET inhibitors and EGFR TKIs [28][20].

4. EGFR TKI Resistance and Fatty Acid Metabolism

In the clinical setting, the presence of EGFR-sensitizing mutations does not guarantee an equal survival benefit in all patients with EGFR-mutant LUAD. Therefore, and besides the inevitable resistance mechanisms, the high variability of response rate must be taken into consideration, demonstrating the urgent need for identifying the factors responsible for this reality. To that end, oneit studywas analyzed the serum metabolic profile of 44 patients with EGFR-mutant LUAD treated with icotinib and divided them into equal groups of good and poor responders, considering progression-free survival longer or shorter than 11 months [37][21]. Among 80 metabolites, a set of seven lipid factors based on their differential expression was able to distinguish good from poor responders. Specifically, lysophosphatidylcholine 16:1, lysophosphatidylcholine 22:5-1, and phosphatidylethanolamine 18:2 were upregulated in good responders, while ceramide 36:1-3, ceramide 38:1-3, sphingomyelin 36:1-2, and sphingomyelin 42:2 were elevated in poor responders [37][21].
Many non-oncological drugs have been repurposed for anti-cancer effects [38][22]. For example, statins are a class of cholesterol-lowering drugs widely prescribed to patients with hyperlipidemia. Intriguingly, there is growing evidence that statins augment the efficacy of EGFR TKIs in a synergistic manner [39,40][23][24]. Interestingly, exposure to gefitinib or erlotinib has been found to significantly downregulate and elevate cholesterol levels in EGFR-mutant sensitive (HCC827, PC9) and resistant (H1975) LUAD cell lines, respectively. The use of statins such as atorvastatin (ATV) has been demonstrated to abrogate the function of caveolin-1 (CAV-1), a factor that regulates cellular cholesterol homeostasis. Indeed, ATV abrogated the expression of CAV-1 and decreased the survival of EGFR-mutant LUAD cells by upregulating apoptosis. Interestingly, a combination of ATV with gefitinib significantly enhanced cell death compared to ATV alone. However, the addition of mevalonate, an intermediate metabolite of cholesterol formation, restricted the tumor cell suppression and reinduced the CAV-1 expression in ATV-treated cells, demonstrating the tight link between cholesterol and CAV-1 [30][25]. Glucose transporters 1 (GLUT-1) and 3 (GLUT-3) are the most upregulated transporters in cancer [41][26], and GLUT-3 is activated through EMT in NSCLC [42][27]. CAV-1 upregulated the expression of GLUT-3, then formed a heterodimer only in PC9-resistant cells increasing glucose uptake, while the EGFR TKI-resistant cells presented a higher dependency on CAV-1/GLUT-3-mediated glucose uptake for their survival compared to sensitive cells. Similarly, in vivo analysis has demonstrated that ATV-treated resistant xenograft models had decreased cholesterol levels inducing downregulation of the CAV-1/GLUT-3 axis, abrogating the glucose uptake, and resulting in lower tumor volumes [30][25].

5. EGFR TKI Resistance and Redox Homeostasis

The cells during physiological processes such as oxidative metabolism or response to cytokines or pathogen infection produce by-products of so-called reactive oxygen species (ROS). When ROS are accumulated without clearance, they induce cell death [48][28]. Moreover, EGFR-mutant LUAD enhances glycolysis to support cell survival. At a specific stage of glycolysis, LUAD cells exert an activating transcription factor 4-mediated metabolic rewiring, shifting glycolysis towards serine synthesis as demonstrated by upregulation of serine synthesis pathway metabolic enzymes such as phosphoserine phosphatase and phosphoglycerate dehydrogenase. Serine is a precursor of cystine which leads to glutathione (GSH) formation, which acts as an antioxidant and participates in ROS scavenging, inhibiting cell death [49][29]. Another study performed RNA sequencing analysis and immunoblotting in EGFR TKI-resistant HCC827 and H1975 models, identifying the upregulation of aldo-keto reductase family 1 member B1 (AKR1B1). Downregulation of AKR1B1 restored the sensitivity to osimertinib both in vitro and in vivo, while its ectopic overexpression rescued the resistant phenotype, revealing a crucial role of AKR1B1 in the occurrence of resistance [33][30]. Transcriptomic and metabolic comparisons of the models identified GSH metabolism as one of the most altered pathways. Specifically, resistant cells demonstrated an upregulation of major metabolites in the GSH de novo synthesis pathway, a finding which was confirmed both in vivo and in relapsed patients who had higher levels of GSH and oxidative GSH in blood compared to EGFR TKI-sensitive patients. Mechanistical studies demonstrated that AKR1B1 promotes the cystine uptake and consequent GSH de novo synthesis by interacting with and activating p-STAT3, which in turn activates cystine transporter SLC7A11/xCT. The elevated levels of GSH act as a major antioxidant, scavenging ROS and protecting tumor cells from treatment-induced stress. Disruption of AKR1B1, either genetically or due to epalrestat, an approved antidiabetic agent, inhibited the increase of GSH. The combination of epalrestat and either gefitinib or osimertinib therefore resulted in the restriction of tumor growth and delayed relapse by abrogating the axis of AKR1B1/p-STAT3/SLC7A11 in resistant models [33][30].
Figure 1. Overview of the metabolic remodeling in EGFR-mutant LUAD and the proposed treatment strategies for circumventing the EGFR TKI resistance. EGFR TKI-resistant LUAD cells secrete lactate, which is incorporated by CAFs located in TME, leading to overproduction of HGF ligands and subsequent activation of MET signaling and its downstream oncogenic effectors such as Ras/Raf/MEK/Erk signaling pathway. Moreover, the FASN-mediated EGFR palmitoylation allows the maintenance of EGFR constitutive signaling in EGFR TKI-resistant cells. Abrogation of palmitic acid synthesis using the anti-obesity drug orlistat (FASN inhibitor) promotes EGFR degradation. The use of statins such as ATV significantly downregulates the cholesterol levels, decreasing glucose uptake and lipogenesis simultaneously in EGFR-mutant LUAD. Further restriction of fatty acid synthesis by inhibiting SREBP1 using PF-429242 impairs both the levels of FASN and LDLR. Interestingly, blocking the PDHK1-mediated phosphorylation of PDH by treating EGFR-mutant LUAD cells with DCA shifts the glucose metabolism towards oxidative phosphorylation, preventing the accumulation of lactate, which has been correlated with EGFR TKI resistance. Furthermore, EGFR TKI-resistant cells have elevated levels of glutathione, the master antioxidant, thus efficiently scavenging ROS, escaping oxidative stress and cell death. Treatment with drugs such as epalrestat and BSO reduces glutathione synthesis, allowing ROS accumulation which eventually leads to ROS-mediated cell death in EGFR TKI-resistant models. Finally, epigenetic downregulation of SDH activity by miR-147b induces TCA cycle arrest and increased levels of succinate in EGFR TKI-tolerant cells.

6. EGFR TKI Resistance and Metabolism-Mediated Stemness

The acquisition of a stem-cell-like phenotype is among the resistance mechanisms that EGFR-mutant LUAD cells develop to tolerate EGFR TKI treatment [54][31]. Indeed, Iroquois-class homeodomain protein 4 (IRX4), a factor that positively regulates pluripotency transcription factors such as NANOG, Sox2, and CD133, providing cells with stemness characteristics, was found to be significantly higher in PC9 gefitinib-resistant cells than PC9 parental cells [35][32]. Of note is the use of 1,25-dihydroxyvitamin D3 (1,25D), the biologically active form of vitamin D which activates the vitamin D receptor (VDR), which has been reported to abrogate a stemness phenotype in ovarian cancer cells [55][33]. Similarly, treating PC9-resistant cells with 1,25D increased VDR expression while significantly diminishing the levels of IRX4 and NANOG by negatively regulating the TGF-β1/SMAD3/IRX4/NANOG axis. Interestingly, a combination of 1,25D with gefitinib resulted in significantly higher efficacy of treatment both in in vitro and in vivo gefitinib-resistant models compared to single treatment. Collectively, impairing stem-like characteristics in EGFR TKI-resistant cells, as in this case by activating the 1,25D/VDR axis, led to resistance mitigation [35][32]. Moreover, preliminary findings suggested that a combination of osimertinib with a novel FASN inhibitor, AZ12756122, presented a synergistic effect overcoming osimertinib resistance in PC9 cells, likely by attenuating cancer stem cell features [36][34].
