Comprehensive analysis of the prognostic and immunological role of cavins in non-small cell lung cancer

Le résumé fourni par la source

Caveolae, specialized and dynamic subdomains of the plasma membrane, have a crucial role in diverse cellular functions encompassing endocytosis, signal transduction, mechanosensation, lipid storage, and metabolism. Cavin family proteins are indispensable for caveolar formation and function. An increasing number of studies have found that cavins are involved in tumor growth, invasion, metastasis, and angiogenesis and may have dual roles in the regulation of cancer. However, the expression and prognostic value of cavins in non-small cell lung cancer (NSCLC) remain unexplored. In this study, the expression, survival data, immune infiltration, and functional enrichment of cavins in patients with NSCLC were investigated using multiple databases. Furthermore, different subtypes of cavin-binding proteins were identified through protein-protein interaction networks and k-means clustering. The results showed that the expression of Cavin-1-3 in NSCLC tissues was significantly lower than that in normal tissues, and that Cavin-2 is the major subtype of cavin that inhibits NSCLC progression. It regulates downstream signaling pathways, modulates the infiltration of immune cells and influences the prognosis of NSCLC. Related experiments also confirmed that Cavin-2 promotes the proliferation and metastasis of NSCLC cells. These findings suggest that cavins and their binding proteins may be novel biomarkers for NSCLC prognosis and immunotherapy, providing new treatment options for NSCLC.
