This review systematically delineates the enzymatic underpinnings of lactylation, its induction via the glycolysis-lactate axis influenced by key TME features (hypoxia, inflammation), and its multifaceted roles in promoting resistance. Specifically, lactylation orchestrates transcriptional reprogramming of resistance-associated genes (e.g., oncogenes, immune checkpoints, epithelial-mesenchymal transition factors), enhances DNA damage repair capacity (e.g., via NBS1/MRE11 lactylation), activates pro-survival autophagy, and modulates immunosuppressive signaling pathways (e.g., PI3K/AKT, NF-κB, JAK/STAT). Furthermore, it facilitates critical resistance phenotypes including immune evasion, metastasis, and angiogenesis. The review summarizes emerging therapeutic strategies targeting lactylation, such as inhibition of lactate production (LDHA/LDHB), lactate transport (MCT1/4), lactyltransferases (e.g., p300), or downstream effectors, highlighting their potential to overcome multifactorial resistance.

Recently, there has been growing interest in how cancer-associated fibroblasts (CAFs) contribute to tumor immune evasion. However, the precise molecular pathways through which CAFs drive immune escape in the context of gastric cancer are not yet fully elucidated. <b>Methods:</b> The abundance of FAP⁺CAFs in gastric cancer tissues was assessed by immunohistochemistry (IHC), and its correlation with tumor sensitivity to PD-1 monoclonal antibody therapy was analyzed. To study the effect of FAP⁺CAFs on naive CD4⁺ T cell differentiation, co-culture experiments were conducted. The underlying molecular mechanisms were further investigated through western blotting and <i>in vivo</i> animal experiments. <b>Results:</b> FAP⁺CAFs were significantly increased in gastric cancer tissues resistant to PD-1 monoclonal antibody, and a positive correlation was found with Th2 cells. Additionally, the expression and secretion of IL-31 in FAP⁺CAFs cells were elevated. Mechanistically, IL-31 interacts with the IL-31R expressed on naive CD4⁺ T cells, leading to the activation of the STAT6 signaling pathway. This cascade facilitates the differentiation of naive CD4⁺ T cells into Th2 cells, thereby contributing to resistance against anti-PD-1 therapy in gastric cancer. <b>Conclusion:</b> FAP⁺CAFs may reduce sensitivity to anti-PD-1 therapy in gastric cancer by promoting Th2 polarization of naive CD4⁺ T cells via the IL-31/STAT6 signaling pathway.

Recent developments have introduced a variety of treatment options that address the molecular diversity of breast cancer; nonetheless, drug resistance remains a significant barrier to achieving favorable results. This review explains the crucial role of genetic and epigenetic changes in contributing to therapeutic resistance, in addition to other factors such as increased drug efflux, enhanced DNA repair, evasion of senescence, tumor heterogeneity, the tumor microenvironment (TME), and epithelial-to-mesenchymal transition (EMT). Genetic modifications, including mutations in oncogenes and tumor suppressor genes, disrupt essential signaling pathways, facilitating resistance to chemotherapy and targeted therapies. At the same time, epigenetic modifications - like DNA methylation, alterations to histones, and dysregulation of non-coding RNAs - reprogram gene expression, supporting adaptive resistance mechanisms. These molecular abnormalities contribute to the plasticity of tumors, allowing cancer cells to evade therapeutic approaches. This review consolidates recent discoveries regarding how these genetic and epigenetic modifications affect treatment responses and resistance in breast cancer, highlighting their interaction with disease advancement. By pinpointing new drug targets, including immunotherapeutic strategies, this article seeks to shed light on the molecular underpinnings of chemoresistance, aiding in the refinement of existing treatment protocols.

We aim to: (i) identify the causes of 5-FU/LV resistance under physiological folate; and (ii) determine if a polymeric fluoropyrimidine (FP) CF10 remains potent to CRC cells selected for 5-FU/LV resistance. <b>Methods:</b> 5-FU/LV-resistant CRC cells were selected by repeated passaging with increasing 5-FU/LV concentrations, and resistance factors were calculated from dose-response studies. Basal and treatment-induced thymidylate synthase (TS), Myc, and ABCB5 were determined by RT-qPCR and Western blot. TS activity was determined using an <i>in situ</i> ³H-release assay.

CF10 remained very potent to CRC cells selected for 5-FU/LV resistance, and CF10 effectively induced TS ternary complex formation and inhibited TS catalytic activity in 5-FU/LV-resistant CRC cells. c-Myc was expressed at ~4-fold higher levels in 5-FU/LV-resistant CRC cells, but Myc was barely detectable with CF10/LV treatment.

Growing evidence highlights the critical role of the tumor microenvironment (TME) in modulating tumor initiation, growth, progression, and, in some cases, suppression. The TME is a complex ecosystem composed of immune cells, cancer-associated fibroblasts, extracellular matrix components, and other factors such as growth factors and cytokines. By shaping tumor cell behavior, the TME facilitates immune evasion and contributes to resistance to treatment. Tumor-associated immune cells, including regulatory T cells, myeloid-derived suppressor cells, and tumor-associated macrophages, contribute to immune suppression and progression. On the other hand, immune activation via immune checkpoint inhibition has shown promise in improving outcomes, especially when combined with other treatments such as transarterial chemoembolization (TACE), selective internal radiation therapy (SIRT), and systemic therapies. Studies have demonstrated the potential of targeting the TME to enhance treatment efficacy, with immune modulation emerging as a key therapeutic strategy.
