A cDNA library was constructed from leaf epidermis of diploid wheat (Triticum monococcum) infected with the powdery mildew fungus (Blumeria graminis f. sp. tritici) and was screened for genes encoding peroxidases. From 2,500 expressed sequence tags (ESTs), 36 cDNAs representing 10 peroxidase genes (designated TmPRX1 to TmPRX10) were isolated and further characterized. Alignment of the deduced a...
Subtilisin propeptide functions as an intramolecular chaperone that guides precursor folding. Nattokinase, a member of subtilisin family, is synthesized as a precursor consisting of a signal peptide, a propeptide, and a subtilisin domain, and the mechanism of its folding remains to be understood. In this study, the essential residues of nattokinase propeptide which contribute to precursor foldi...
Myostatin is a negative regulator of skeletal muscle growth and belongs to the TGF-β superfamily of growth and differentiation factors. Myostatin functions by inhibiting myoblast proliferation and differentiation (Thomas, 2000; Rios, 2001; Taylor, 2001; Langley, 2000). Mutations in the myostatin gene are found in cattle such as Belgian Blue and Piedmontese (McPerron et al, 1997;Kambadur, 1997; ...
Candida antarctica lipase B (CalB) is an important catalyst in bio-organic synthesis. To optimize its performance, either the reaction medium is changed or the lipase itself is modified. In the latter case, mutants are generated in Eschericha coli and subsequently expressed in fungal hosts for their characterization. Here we present the functional expression of CalB in the periplasm of E. coli....
Patients with chronic kidney disease (CKD) have higher rates of fracture than the general population. Increased bone remodeling, leading to microarchitectural deterioration and increased fragility, may accompany declining kidney function, but there are no reliable methods to identify patients at increased risk for fracture. In this cross-sectional study of 82 patients with predialysis CKD, high...
CONTEXT Increased bone fragility is a frequent complication of hypercortisolism due predominantly to suppression of bone formation. Sclerostin is an osteocyte-produced negative regulator of bone formation, which is up-regulated by glucocorticoids in mice. OBJECTIVE Our objective was to assess the effect of endogenous hypercortisolism on circulating sclerostin and bone turnover in humans. DE...
BACKGROUND Myocardial fibrosis is a potential pathophysiological mechanism leading to systemic right ventricular (SRV) deterioration. We hypothesize that circulating levels of collagen deposition markers are elevated in patients with SRV remodeling and this elevation may have a predictive value. METHODS We prospectively evaluated 56 patients with D-TGA after the atrial switch procedure (mean ...
