Abstract
Cancer-associated fibroblasts (CAFs) play a central role in cancer progression and are involved in modulating cancer cell proliferation, invasion, metastasis, drug resistance and so on. Receptor Interacting Serine/Threonine Kinase 4 (RIPK4) was demonstrated to promote gastric cancer (GC) metastasis and tumorigenesis. Here, this study aimed to explore whether GC-derived CAFs affected cisplatin (DDP) resistance in GC cells via RIPK4. DDP-resistant GC cells were first established. Levels of RIPK4 mRNA and proteins were detected using qRT-PCR and western blotting. The IC50 values of DDP, cell proliferation, invasion, and migration were analyzed using MTT, 5-ethynyl-2′-deoxyuridine, transwell, and wound healing assays, respectively. PI3K/AKT pathway-related proteins were measured by western blotting. Animal experiments were performed for in vivo analysis. Here, we found that CAFs enhanced DDP resistance in DDP-resistant cells by promoting cell proliferation, invasion and migration. CAFs led to an increased RIPK4 expression in DDP-resistant cells. The silencing of RIPK4 suppressed DDP resistance in DDP-resistant cells. Moreover, RIPK4 silencing in CAFs could also reduce DDP resistance in GC. Mechanistically, CAFs could activate the PI3K/AKT pathway by RIPK4. In vivo assay also showed that RIPK4 silencing in CAFs attenuated CAF-induced DDP resistance. In conclusion, RIPK4-decreased CAFs suppressed DDP resistance in GC by blocking the activation of the PI3K/AKT pathway, recommending a novel method for overcoming DDP resistance in gastric cancer.
期刊介绍:
The Journal of Biochemical and Molecular Toxicology is an international journal that contains original research papers, rapid communications, mini-reviews, and book reviews, all focusing on the molecular mechanisms of action and detoxication of exogenous and endogenous chemicals and toxic agents. The scope includes effects on the organism at all stages of development, on organ systems, tissues, and cells as well as on enzymes, receptors, hormones, and genes. The biochemical and molecular aspects of uptake, transport, storage, excretion, lactivation and detoxication of drugs, agricultural, industrial and environmental chemicals, natural products and food additives are all subjects suitable for publication. Of particular interest are aspects of molecular biology related to biochemical toxicology. These include studies of the expression of genes related to detoxication and activation enzymes, toxicants with modes of action involving effects on nucleic acids, gene expression and protein synthesis, and the toxicity of products derived from biotechnology.
