Discrepancies in the response to drugs are partially due to polymorphisms in genes involved in drug metabolism and transport. The frequency, pattern and impact of these polymorphisms vary among populations. In the present study, the pharmacokinetics and pharmacogenetics of atorvastatin (ATV) in a Mexican population were investigated. The study cohort exhibited differing ATV metabolizing phenotypes, and in subsequent allelic discrimination assays, single nucleotide polymorphisms in the angiotensinogen, angiotensin II type 1 receptor (AGTR1) and bradykinin B2 receptor (BDKRB2) genes were genotyped and their effects on the pharmacokinetic parameters of ATV were assessed...

The treatment of refractory ascites due to cirrhosis is a clinical challenge for hepatologists. Tolvaptan, a novel aquaporin modulator, was made available in Japan in 2013 for the treatment of patients with refractory ascites due to cirrhosis. Despite the potential of this drug, few reports are available regarding its clinical use. The aim of the present study was to clarify the efficacy of tolvaptan in patients with refractory ascites due to cirrhosis and to review the clinical outcomes of treatment. Medical records were retrospectively reviewed for 65 patients with refractory ascites due to cirrhosis who were treated daily with 7...

Otto Warburg observed in 1924 that cancer cells were dependent exclusively on glycolysis for the production of energy even in the presence of oxygen (the 'Warburg effect'). Consequently, cancer cells require ~19 times more glucose uptake to obtain equivalent amounts of energy as normal cells. The Warburg effect is the scientific basis for positron emission tomography (PET), which has markedly improved cancer detection. During chemotherapy, cancer cells may upregulate their expression of multi-drug resistance proteins and ultimately cause treatment failure...

The causative agent of acquired immune deficiency syndrome (AIDS) is human immunodeficiency virus (HIV). Since its discovery before 30 years, a number of drugs known as highly active antiretroviral therapy have been developed to suppress the life cycle of the virus at different stages. With the current therapeutic approaches, ending AIDS means providing treatment to 35 million individuals living with HIV for the rest of their lives or until a cure is developed. Additionally, therapy is associated with various other challenges such as potential of drug resistance, toxicity and presence of latent viral reservoir...

Hepatocyte growth factor (HGF) is produced by stromal and mesenchymal cells, and it stimulates epithelial cell proliferation, motility, morphogenesis and angiogenesis in various organs via tyrosine phosphorylation of its cognate receptor, Met. The HGF-Met signaling pathway contributes in a paracrine manner to the development of epithelial organs, exerts regenerative effects on the epithelium, and promotes the regression of fibrosis in numerous organs. Additionally, the HGF-Met signaling pathway is correlated with the biology of cancer types, neurons and immunity...
