In diabetic patients complicated with colorectal cancer (CRC), metformin treatment was reported to have diverse correlation with CRC-specific mortality. In laboratory studies, metformin was reported to affect the survival of cancer stem cells (CSCs) in breast and pancreatic cancers and glioblastoma. Although cscs play a critical role in the resistance to(More)
OBJECTIVES The methylenetetrahydrofolate dehydrogenase (MTHFD1) gene, as one of the key genes involved in the folate pathway, has been reported to play a critical role in the pathogenesis of neural tube defects (NTDs). However, the results of published studies are contradictory and inconclusive. Thus, this meta-analysis aimed to evaluate the effect of the(More)
BACKGROUND The overexpression of key enzymes in a metabolic pathway is a frequently used genetic engineering strategy for strain improvement. Metabolic control analysis has been proposed to quantitatively determine key enzymes. However, the lack of quality data often makes it difficult to correctly identify key enzymes through control analysis. Here, we(More)
Depression is one of the major side effects of interferon alpha (IFN-α) treatment, but the molecular mechanism underlying IFN-α-induced depression remains unclear. Several studies have shown that the serotonin receptors 5-HTR1b and 5-HTR4 play key roles in the anti-depression effects associated with p11 (S100A10). We investigated the effects of IFN-α on the(More)
Drug-induced liver injury (DILI) is a well-recognized adverse event of anti tuberculosis drugs (ATD) possibly associated with genetic variations. The objective of this study was to perform genome-wide association study (GWAS) to identify genetic variants associated with the risk for ATD induced liver toxicity in Ethiopian patients. Treatment-naïve newly(More)
A Sec14-like protein, ZmSEC14p , from maize was structurally analyzed and functionally tested. Overexpression of ZmSEC14p in transgenic Arabidopsis conferred tolerance to cold stress. Sec14-like proteins are involved in essential biological processes, such as phospholipid metabolism, signal transduction, membrane trafficking, and stress response. Here, we(More)
As 5-aminolevulinic acid synthase (ALAS), the key enzyme for 5-aminolevulinic acid (ALA) synthesis, is unstable, we have sought to find thermostable ALASs from thermophilic organisms. Three ALASs from thermophiles Geobacillus thermoglucosidasius (GT-ALAS), Laceyella sacchari (LS-ALAS) and Pseudomonas alcaliphila (PA-ALAS) were purified and characterized.(More)
The 70 kDa zeta-chain associated protein kinase (ZAP-70) plays a critical role in effective signal transductions that are fundamental to T cell differentiation, proliferation and effector functions. In this paper, the ZAP-70 gene of Nile tilapia, Oreochromis niloticus (designated as On-ZAP-70) was cloned and its expression pattern under the stimulation of(More)
