PXR1 knockdown boosts VitK3 anticancer effects

04/01/2016 by Philippe Fixe, PhD 1 Comment
HeLa cells in fluorescent microscopy

The anti-cancer property of the Vitamin K3 (Vitk3) was again recently studied by Dr Meng-Er Huang’s team (Curie Institute, CNRS UMR3348, Paris).
By using in vitro pro-oxydative cellular models, Dr Huang and collaborators observed a cancer-selective cytotoxicity of vitk3 in Peroxyredoxin 1 (PRDX1 aka PRX1)-deficient cancer cell lines.
To further investigate the underlying molecular mechanisms, the authors used a stably PRX1-depleted HeLa cell line (PRX1-) (vs. Control (PRX1+)) under various experimental conditions. They notably treated PRX1- and PRX1+ cell lines by vitk3 and 6 other known anticancer molecules targeting different cellular events (microtubule (vinblastine & taxol); DNA (doxorubicin & daunorubicin); DNA transcription (actinomycin D) and cell cycle (5-FU)).
