Targeted therapy with epidermal growth factor receptor tyrosine kinase inhibitors(EGFR-TKIs) is the standard first-line treatment for advanced EGFR-mutated non-small cell lung cancer (NSCLC). Third-generation EGFR-TKIs, represented by osimertinib, have been approved to overcome the EGFR T790M mutation in patients who are resistant to first- or second-generation TKIs, which brings more survival benefits for patients with advanced NSCLC. However, resistance to the third generation of EGFR-TKIs is still inevitable. Acquired drug resistance is the main reason for limiting the long-term effectiveness of targeted therapy in EGFR-mutated NSCLC patients. The mechanism of EGFR-TKI resistance of the third generation has become a focus of research in the field of targeted therapy. In this review, we summarize the research progress in resistance mechanisms of advanced NSCLC to osimertinib and the potential overcoming strategies and hope to provide a clinical basis and ideas for precision treatment of NSCLC.

The process by which cells translate external mechanical cues into intracellular biochemical signals involves intricate mechanisms that remain unclear. In recent years, research into post-translational modifications (PTMs) has offered valuable insights into this field, spotlighting protein prenylation as a crucial mechanism in cellular mechanotransduction and various human diseases. Protein prenylation, which involves the covalent attachment of isoprenoid groups to specific substrate proteins, profoundly affects the functions of key mechanotransduction proteins such as Rho, Ras, and lamins.

Fibrosis accounts for approximately one-third of disease-related deaths globally. Current therapies fail to cure fibrosis, emphasizing the need to identify new antifibrotic approaches. Fibrosis is defined by the excessive accumulation of extracellular matrix (ECM) and resultant stiffening of tissue stroma.

Diabetes is becoming more common worldwide, and people with diabetes are twice as likely to experience heart problems compared to those without diabetes. These cardiovascular complications are the foremost cause of mortality among people with diabetes. A specific form of heart failure known as "diabetic cardiomyopathy" can develop in individuals with diabetes.

Multiple myeloma (MM) remains incurable and patients eventually face the relapse/refractory dilemma. B cell maturation antigen (BCMA)-targeted immunotherapeutic approaches have shown great effectiveness in patients with relapsed/refractory MM, mainly including chimeric antigen receptor T cells (CAR-T), bispecific T cell engagers (TCEs), and antibody-drug conjugates (ADCs). However, their impact on long-term survival remains to be determined.
