The recent identification of several additional members of the family of sugar transport facilitators (gene symbol SLC2A, protein symbol GLUT) has created a heterogeneous and, in part, confusing nomenclature. Therefore, this letter provides a summary of the family members and suggests a systematic nomenclature for SLC2A and GLUT symbols.
Through short-term exposure (7-d exposure), long-term exposure (16-d exposure) and exposure-recovery (7-d exposure + 9-d recovery), the bioaccumulation and distribution of La and Ce and their effects on growth of wheat seedlings were studied. Addition of La (0.5-25 mg/l) and Ce (0.5-25 mg/l) to the culture medium individually and in combination inhibited(More)
BACKGROUND Surgery for pancreatic endocrine tumors (PETs) with blood vessel involvement is controversial. HYPOTHESIS Resection of PETs with major blood vessel involvement can be beneficial. DESIGN The combined databases of the National Institutes of Health and Stanford University hospitals were queried. MAIN OUTCOME MEASURES Operation, pathologic(More)
Elemental chemical speciation in atmospheric particles determining their bioavailability and toxicity is an implication for human health assessment. Total suspended particulates (TSP) and fine particulate matter (PM2.5) in summer and winter (Nanjing, China) were therefore collected for assessing the fractionation and human health risks associated with As(More)
Reductions of carbonyl groups catalyzed by oxidoreductases are involved in all biological processes and are often a class of important biocatalyst. In this article, we report a novel enzyme designated as diketoreductase (DKR) that was able to reduce two carbonyl groups in a diketo ester to corresponding dihydroxy ester with excellent stereoselectivity. The(More)
Pancreatic cancer is one of the deadliest diseases largely due to difficulty in early diagnosis and the lack of effective treatments. KRAS is mutated in more than 90% of pancreatic cancer patients, and oncogenic KRAS contributes to pancreatic cancer tumorigenesis and progression. In this report, using an oncogenic KRASV12-based pancreatic cancer cell model,(More)
Statins, including atorvastatin (Lipitor®), are the top-selling drugs in the world. The biocatalytic production of chiral side chains of statin drugs is of great interest to academia and industry. Stereoselective double reduction of a β,δ-diketo ester catalyzed by a diketoreductase offers a simple and efficient route for the preparation of statin side(More)
A simple and reliable chiral HPLC method was developed for the determination of enantiomeric excess of a chiral dihydroxy intermediate for the chemoenzymatic synthesis of side chain of statin drugs. After evaluating different columns and conditions, the four stereoisomers of ethyl 3,5-dihydroxy-6-benzyloxy hexanoate were well resolved by a simple gradient(More)
It is well known that non-aqueous enzymatic catalysis has emerged as an important area of enzyme engineering with the advantages of higher substrate solubility, increased stereoselectivity, modified substrate specificity and suppression of unwanted water-dependent side reactions. As a result, non-aqueous enzymatic catalysis has been applied in the(More)
