Abstract Cytochromes P450 (CYPs) play a prominent role in catalyzing phase I xenobiotic biotransformation and account for about 75% of the total metabolism of commercially available drugs, including chemotherapeutics. The gene expression and enzyme activity of CYPs are variable between individuals, which subsequently leads to different patterns of susceptibility to carcinogenesis by genotoxic xenobiotics, as well as differences in the efficacy and toxicity of clinically used drugs. This research aimed to examine the presence of the CYP2B6*9 polymorphism and its possible association with the incidence of B-CLL in Egyptian patients, as well as the clinical outcome after receiving cyclophosphamide chemotherapy.

Abstract Tripterygium wilfordii has been renowned mostly because of the anticancer effects of its root extracts, which is partly ascribed to the presence of celastrol, a pentacyclic triterpenoid, as one of the main active components. Celastrol also has recently been reported as an effective prodrug in the treatment of obesity. Despite the promising activities, the pathway leading to celastrol biosynthesis, especially cytochrome P450 (CYP) enzyme(s) that occur in its downstream steps, are largely unknown. This study conducted a comparative analysis of the T. wilfordii transcriptome derived from its root and leaf tissues. Differential gene expression analysis identified a number of root-specific… More >
