Antibiotics could act synergistically to combat the protection conferred to clinical isolates of Stenotrophomonas maltophilia by biofilms. Macrolide antibiotics may be effective where used in combination.
Hexavalent chromium (Cr (VI)), which is a recognized human carcinogen, is widely used in industrial production of raw materials. Evidence verifies that environmental contaminants in the urine can induce malignant transformation in the urinary bladder tract, and our data indicate that Cr (VI) could promote the proliferation and migration and inhibit the apoptosis of bladder cancer (BLCA) cells. However, the molecular mechanism remains ambiguous. We find that Filamin A (FLNA) is overexpressed in BLCA, and Cr (VI) promotes epithelial-to-mesenchymal transition by regulating FLNA in BLCA. Thus, inhibiting the expression of FLNA may be a prospective method for limiting the BLCA progression caused by Cr (VI) exposure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
