This study was aimed to identify the monocarboxylate transporters (MCTs) in HeLa cells and to delineate their role in transportation of L-lactic acid. The functional role of MCTs in lactic acid transport was evaluated at various mucosal pHs (4.5-7.4) or

Protein-RNA interactions are involved in all facets of RNA biology. The identification of small molecules that selectively block such bimolecular interactions could provide insight into previously unexplored steps of gene regulation. Such is the case for regulation of eukaryotic protein

In the present study the existence of a non-AT(1), non-AT(2) angiotensin (Ang) binding site unmasked by the organomercurial protease inhibitor p-chloromercuribenzoate (PCMB) was demonstrated in mouse brain membranes, consistent with observations previously reported in the rat (Karamyan and Speth, 2007b).
