α-Ketoglutarate (AKG) is a key intermediate in glutamine metabolism. Emerging evidence shows beneficial effects of AKG on clinical and experimental nutrition, particularly with respect to intestinal growth and integrity. However, the underlying mechanisms are unknown. Intestinal porcine epithelial cells (IPEC-1) were used to test the hypothesis that AKG(More)
The recent sequencing of the DNA region of the geldanamycin post-polyketide synthase (PKS) modification gene clusters revealed the presence of two regulatory genes: gdmRI (2,907 bp) and gdmRII (2,766 bp). The deduced products of gdmRI and gdmRII (968 and 921 amino acid residues, respectively) were identified as homologues of the LuxR transcriptional(More)
BACKGROUND Current staging methods do not accurately predict the risk of disease recurrence and benefit of adjuvant chemotherapy for patients who have had surgery for stage II colon cancer. We postulated that expression patterns of multiple microRNAs (miRNAs) could, if combined into a single model, improve postoperative risk stratification and prediction of(More)
Coronary artery disease (CAD) causes more than 700,000 deaths each year in China. Previous genome-wide association studies (GWAS) in populations of European ancestry identified several genetic loci for CAD, but no such study has yet been reported in the Chinese population. Here we report a three-stage GWAS in the Chinese Han population. We identified a new(More)
The aberrant activation of sonic hedgehog (SHH) pathway contributes to initiation and progression of various malignancies. However, the roles and underlying mechanisms of SHH signaling pathway in invasion and metastasis of liver cancer have not been well understood. In this study, we found that SHH signaling was activated and correlated with invasion and(More)
Bacillus subtilis is one of the most studied gram-positive bacteria. In this work, YvgN and YtbE from B. subtilis, assigned as AKR5G1 and AKR5G2 of aldo-keto reductase (AKR) superfamily. AKR catalyzes the NADPH-dependent reduction of aldehyde or aldose substrates to alcohols. YvgN and YtbE were studied by crystallographic and enzymatic analyses. The apo(More)
The purpose of this study was to prepare and evaluate a taste-masked berberine hydrochloride orally disintegrating tablet for enhanced patient compliance. Taste masking was performed by coating berberine hydrochloride with Eudragit E100 using a fluidized bed. It was found that microcapsules with a drug–polymer ratio of 1:0.8 masked the bitter taste(More)
BACKGROUND Hepatocellular carcinoma (HCC) has a high predilection for portal vein invasion. Furthermore, the treatment of HCC with portal vein tumor thrombosis (PVTT) is controversial. The objective of this study was to investigate clinicopathologic characteristics and surgical outcomes of HCC patients with PVTT. METHODS The clinicopathologic data and(More)
Branched-chain amino acids (BCAA) are actively taken up and catabolized by the mammary gland during lactation for syntheses of glutamate, glutamine and aspartate. Available evidence shows that the onset of lactation is associated with increases in circulating levels of cortisol, prolactin and glucagon, but decreases in insulin and growth hormone. This study(More)
Lactation is associated with elevated catabolism of branched-chain amino acids (BCAA) in mammary glands to produce glutamate, glutamine, alanine, aspartate, and asparagine. This study determined effects of metabolic fuels on the catabolism of leucine (a representative BCAA) in bovine mammary epithelial cells. Cells were incubated at 37 °C for 2 h in Krebs(More)
