Solid tumor cells are known to be highly glycolytic and, to prevent apoptosis by cellular acidosis, cells increase proton efflux through pH regulators, such as monocarboxylate transporters (MCTs). However, the role of these membrane proteins in solid tumor development and survival is not fully understood. We aimed to evaluate the expression of the MCT(More)
Due to the highly glycolytic metabolism of solid tumours, there is an increased acid production, however, cells are able to maintain physiological pH through plasma membrane efflux of the accumulating protons. Acid efflux through MCTs (monocarboxylate transporters) constitutes one of the most important mechanisms involved in tumour intracellular pH(More)
Hybrid capture is an easy and highly sensitive technique for screening population due to its capacity to detect malignant and premalignant lesions of the cervix. To evaluate its sensitivity, we investigated the frequency of high-risk human papillomavirus (HPV) infection and its correlation with glandular malignant lesions, analyzing a total of 113 cases of(More)
Deregulation of cellular energetic metabolism was recently pointed out as a hallmark of cancer cells. This deregulation involves a metabolic reprogramming that leads to a high production of lactate. Lactate efflux, besides contributing for the glycolytic flux, also acts in the extracellular matrix, contributing for cancer malignancy, by, among other(More)
After a reminder of the major points of the pharmacokinetics of non-steroid anti-inflammatory drugs, the authors report the results of a multicentric study of the kinetics of naproxen after oral intake of one single dose of 1 gram in patients with rheumatoid arthritis. The half-life is longer in the synovial fluid than in the serum, 23 hours versus 17(More)
