Accumulating evidences have indicated that BIM expression largely decides the development of lung cancer and outcome of EGFR-mutant lung cancers after TKI treatments. BIM polymorphism is a 2,903-bp deletion in the second exon. To clarify the relationship between this BIM polymorphism and clinical outcomes of lung cancers, we conducted this meta-analysis and observed the survival and responses to TKIs. Sixteen cohort studies, covering 4393 WT and 916 BIM deletion patients were included. Overall, BIM deletion polymorphism was associated with significantly shorter progression-free survival (PFS) and slightly shorter overall survival (OS), compared to the WT group...

Dimethyl sulphoxide (DMSO) is widely used as a solvent in biomedical research, regularly in concentrations up to 1%. Nevertheless, little is known about the effect of different DMSO concentration on WM-266-4 metastatic melanoma cells, which are often used in melanoma research. Due to resistance of melanoma cells high concentrations of cytotoxic substances soluble in DMSO are used in vitro tests. Consequently, total DMSO concentration often exceeds 1%. The aim of our study was to test the metabolic activity and morphology of WM-266-4 cells exposed to selected DMSO concentrations for different period of time...

MicroRNAs (miRNAs) play important roles in melanoma. Although miR-637 has been suggested to be a tumor suppressor in several cancers, its function in melanoma and the molecular mechanism behind that function remain unclear. In this study, we investigated the role of miR-637 in human melanoma and explored its relevant mechanisms. We found that the expression of miR-637 is significantly downregulated in melanoma tissues and cell lines. While overexpression of miR-637 inhibited melanoma cell proliferation and cell cycle G1-S transition, and induced apoptosis...
