Project description:Insulin degrading enzyme (IDE) is a major enzyme responsible for insulin degradation in the liver. The modulation of insulin degrading enzyme activity is hypothesized to be a link between T2DM and liver cancer. Results provide insight into role of IDE in proliferation and other cell functions.
Project description:Insulin degrading enzyme (IDE) is a major enzyme responsible for insulin degradation in the liver. The modulation of insulin degrading enzyme activity is hypothesized to be a link between T2DM and liver cancer. Results provide insight into role of IDE in proliferation and other cell functions. HepG2 cells were transfected with 96nM siRNA for IDE or AllStars Negative Control siRNA (Qiagen) using Lipofectamine 2000 (Invitrogen). 16 h after transfection, cells were treated with 10 nM insulin (Sigma Aldrich) or vehicle for 24 h in serum starvation condition. Total RNA was extracted. For each of the 4 conditions, 3 biological replicates were included.

Project description:To explore the effect of POX03070 on transcription levels of plant-biomass-degrading enzyme-encoding genes in Penicillium oxalicum,and the interaction between POX03070 and PoxCxrA in transcriptional level.
Project description:Transcriptomic profiling and real-time quantitative reverse transcription-PCR analyses revealed that TP05746 dynamically regulated the expression of genes encoding major PBDEs. Furthermore, in vitro binding experiments confirmed that TP05746 directly bound to the promoter regions of these major enzyme genes. Transcription factors mediated the regulation of plant-biomass-degrading enzyme (PBDE) gene expression in Talaromyces pinophilus.
Project description:The sequence-specific transcription factors Ume6, Nrg1, Cin5, and Sok2 and the general transcription factor TFIIB mediate the genome-wide targeting of the ATP-dependent chromatin remodeling enzyme Isw2.
Project description:Although aging is a physiological process to which all organisms are subject, the presence of obesity and type 2 diabetes accelerates biological aging. Recent studies have demonstrated the causal relationships between dietary interventions suppressing obesity and type 2 diabetes and delaying the onset of age-related endocrine changes. Curcumin, a natural antioxidant, has putative therapeutic properties such as reinstating insulin sensitivity in obese mice. However, how curcumin contributes to maintaining insulin homeostasis in aged organisms largely remains unclear. Thus, the objective of this study is to examine the pleiotropic effect of dietary curcumin on insulin homeostasis in a diet-induced obese (DIO) aged mouse model. Aged (18-20 months old) male mice given a high-fat high-sugar diet supplemented with curcumin displayed a different metabolic phenotype compared to mice given a high-fat high-sugar diet alone. Furthermore, curcumin supplementation altered hepatic gene expression profiling, especially insulin signaling and senescence pathways. We then mechanistically investigated how curcumin functions to fine-tune insulin sensitivity. We found that curcumin supplementation increased hepatic insulin degrading enzyme (IDE) expression levels and preserved islet integrity, both of which are beneficial during aging. Our findings suggest that the multifaceted therapeutic potential of curcumin can be used as a protective agent for age-induced metabolic diseases.
