Bacterial Dsb enzymes are involved in the oxidative folding of many proteins, through the formation of disulfide bonds between their cysteine residues. The Dsb protein network has been well characterized in cells of the model microorganism Escherichia coli. To gain

Protein tyrosine phosphatase 1B (PTP1B) negatively regulates insulin signalling. PTP1B deficiency improves obesity-induced insulin resistance and consequently improves type 2 diabetes in mice. Here, the small molecule norathyriol reversed obesity- and high-fat-diet-induced insulin resistance by inhibiting PTP1B. The inhibitory mode

Recent studies have revealed that osteocytes play multiple important physiological roles. To analyze osteocyte functions in detail, an in vitro experimental system for primary osteocytes would be useful. Unfortunately, osteocytes tend to dedifferentiate and acquire osteoblast-like features even when the

Clopidogrel is an oral antiplatelet prodrug, the majority of which is hydrolyzed to an inactive metabolite by hepatic carboxylesterase 1 (CES1). Most angiotensin-converting enzyme inhibitors (ACEIs) are also metabolized by this enzyme. We examined the effects of ACEIs on clopidogrel
