Genetic Determinants of Response to Statins in Cardiovascular Diseases.

Despite extensive efforts to identify patients with cardiovascular disease (CVD) who could most benefit from the treatment approach, patients vary in their benefit from therapy and propensity for adverse drug events. Genetic variability in individual responses to drugs (pharmacogenetics) is considered an essential determinant in responding to a drug. Thus, understanding these pharmacogenomic relationships has led to a substantial focus on mechanisms of disease and drug response. In turn, understanding the genomic and molecular bases of variables that might be involved in drug response is the main step in personalized medicine. There is a growing body of data evaluating drug-gene interactions in recent years, some of which have led to FDA recommendations and detection of markers to predict drug responses (e.g., genetic variant in VKORC1 and CYP2C9 genes for prediction of drug response in warfarin treatment). Also, statins are widely prescribed drugs for the prevention of CVD. Atorvastatin, fluvastatin, rosuvastatin, simvastatin, and lovastatin are the most common statins used to manage dyslipidemia. This review provides an overview of the current knowledge on the pharmacogenetics of statins, which are being used to treat cardiovascular diseases.

Targeting the Transforming Growth Factor-beta Signaling Pathway in the Treatment of Gynecologic Cancer.

The transforming growth factor-beta (TGF-ß) signaling pathway has been reported to be dysregulated in the pathogenesis of several malignancies, including gynecologic cancers. This provides proof of concept of its potential value as a therapeutic target and prognostic biomarker in cervical cancer. Here we provide an overview of the biological role and clinical impact of TGF-ß inhibitors either as a single agent or as a combinatorial therapy in gynecological cancers, concentrating on phase I to phase II/III clinical trials. Aberrant TGF-ß signaling may lead to carcinogenesis. Inhibition of TGF-ß represents an interesting area of focus for the treatment of gynecological cancer. Several TGF-ß inhibitors are potential anticancer agents and are undergoing clinical trials in cancer, including galunisertib, dalantercept, and vigil. There is a growing body of data showing the potential therapeutic impact of targeting the TGF-ß pathway in different cancer types, although further studies are still warranted to explore the value of this strategy and finding the most appropriate patients who could most benefit from therapy.
