Description:
Bladder cancer (BC) is a frequently diagnosed malignancy affecting predomi�nantly adult and elderly populations. It is expected that due to the longer life time, BC will become even more frequent in the future; thus in consequence, it will rep�resent serious health problem of older society part. The treatment of advanced BC is mostly ineffective due to its very aggressive behavior. So far, no effective targeted therapy is used for BC treatment. Here, we found that BC is characterized by lower protein levels of BRM, INI1, and BAF155 main subunits of SWI/SNF chromatin remodeling complex (CRC) which is involved in global control of gene expression and influences various important cellular processes like: cell cycle con�trol, apoptosis, DNA repair, etc. Moreover, the expression of SMARCA2, a BRM encoding gene, strongly correlated with BC metastasis and expression of such metabolic genes as PKM2 and PRKAA1. Furthermore, the analysis of T24 and 5637 commonly used BC cell lines revealed different expression levels of meta�bolic genes including FBP1 gene encoding Frutose-1,6-Bisphosphatase, an enzyme controlling glycolysis flux and gluconeogenesis. The tested BC cell lines exhibited various molecular and metabolic alterations as well as differential glucose uptake, growth rate, and migration potential. We have shown that BRM subunit is involved in the transcriptional control of genes encoding metabolic enzymes. Moreover, we found that the FBP1 expression level and the SWI/SNF CRCs may serve as markers of molecular subtypes of BC. Collectively, this study may provide a new knowledge about the molecular and metabolic BC subtypes which likely will be of high importance for the clinic in the future.
