The altered activity of drug metabolism enzymes (DMEs) is a hallmark chemotherapy resistance. Cytochrome P450s (CYPs), mainly CYP3A4, and several oxidoreductases are responsible for Phase I doxorubicin (DOX), an anthracycline widely used in breast cancer (BC) treatment. This study aimed to investigate the role DMEs involved first stages acquisition DOX-resistance BC cells. For this purpose, expression 92 DME genes specific CYP-complex activities were assessed either sensitive (MCF-7 parental...

Progesterone receptor membrane component 1 (PGRMC1) is one of few proteins that have been recently described as direct modulators the activity human cytochrome P450 enzymes (CYP)s. These form a superfamily membrane-bound hemoproteins metabolize wide variety physiological, dietary, environmental, and pharmacological compounds. Modulation CYP impacts detoxification xenobiotics well endogenous pathways such steroid fatty acid metabolism, thus playing central role in homeostasis. This review...

<title>Abstract</title> Endogenous androgens are pivotal in the development and progression of prostate cancer (PC). We investigated nanoparticle formulations curcumin piperine modulating steroidogenesis within PC cells. Using multiple cell lines (LNCaP, VCaP, DU145 PC3) we studied effects curcumin, piperine, their formulations—curcumin nanoparticles, curcumin-piperine nanoparticles (CPN)—on viability, migration, steroid biosynthesis. Curcumin its significantly reduced viability cells, with...
