Transcriptome analysis of Wild Type and ΔfadR in Shewanella oneidensis MR-1

ABSTRACT: Purpose: The goals of this study are to find out the differential expression genes in the fadR mutant strain(ΔfadR) compared with wild-type (WT) and to further explore the regulation mechanisms of fadR. Methods: Shewanella oneidensis MR-1 WT and ΔfadR were collected in log phage(OD~0.6). RNA extraction was performed using the RNeasy minikit (Qiagen) and the RNA was quantified by using a NanoVue spectrophotometer (GE Healthcare). RNA seq was performed using Illumina NextSeq 500, 2×150 bp. Results: Our study represents that the expression of 146 genes were decreased and 94 genes were increased inΔfadR compared with WT. Branched-chain keto acid dehydrogenase (BKD) produces corresponding branched-chain acyl coenzyme A which further participating branchend-chain fatty acids synthesis. The expression of bkdA2 was also promoted in △fadR compared with WT. Conclusions: Combined with our expression results, it declared that FadR can suppress bkd operon in some degree,which further increase the synthesis of branched-chain fatty acids in ΔfadR.

Gene expression profiles in cardiac specific overexpression of Glut1 transgenic mice

Project description:Cardiac-specific Glut1 transgenic (Glut1-TG) mice exhibited higher glucose uptake and utilization compared with wild type mice. Cardiac pathological hypertrophy is accompanied by a switch of substrate metabolism from fatty acid oxidation to glucose use, resulting in a fetal like metabolic profile. However, the role of increasing glucose utilization in regulating cardiomyocyte growth is poorly understood. In order to identify novel pathways that is regulated by glucose, we performed microarray analyses using hearts from Glut1-TG and WT mice. The microarray analyses revealed that many genes that are involved in branched-chain amino acids (BCAAs) were downregulated in Glut1-TG mice.

Impact of Preoperative Oral Branched-chain Amino Acids on Reducing Postoperative Insulin Resistance.

Project description:Postoperative insulin resistance refers to the phenomenon that the body’s glucose uptake stimulated by insulin is reduced due to stress effects such as trauma or the inhibitory effect of insulin on liver glucose output is weakened after surgery. There is a clear link between postoperative insulin resistance and poor perioperative prognosis. Therefore, exploring interventions to reduce postoperative stress insulin resistance, stabilize postoperative blood glucose, and reduce postoperative complications are clinical problems that need to be solved urgently. In recent years, research on branched-chain amino acids and metabolic diseases has become a hot spot. Studies have found that in the rat model, preoperatively given a high branched-chain amino acid diet can inhibit postoperative insulin resistance and stabilize blood glucose levels. This research plan is to try to add branched-chain amino acids before surgery to observe the occurrence of postoperative insulin resistance in patients.

Effect of embryo lysates treatment on gene expression.

Project description:To systematically evaluate the effect of embryo lysates feeding, we conducted RNA sequencing (RNA-seq) on day 7 N2 worms treated with embryo lysates. Our findings revealed that embryo lysates affected the expression of genes related to fatty acid metabolism, degradation of branched-chain amino acids, and lysosome functions. Notably, worms treated with embryo lysates showed increased fatty acid degradation gene expression and decreased fatty acid elongation gene expression.

Kidney of MFP2-/-

Project description:The MFP2-/- (multifunctional protein 2) is a multifunctional enzyme with discovery in connection with different metabolic pathways. It is involved in beta-oxidation of branched fatty acids and long chain fatty acids in peroxisomes and in sythesis of bile fatty acids. MFP2 knock out mouse was made with a phenotype only visible in homozygotes (severe growth retardation, 40% mortality during the first week after birht, reduction of fertility in males, less activity). The studies have been performed to identify changes in gene expression levels in kidney due to clinical chemical changes in the phenotype of this mutant mouse line during a screening in the German Mouse Clinic. Keywords: dual colour hybridisation on cDNA microarrays, MFP2, Hsd17b4, kidney DNA chip technology has been exploited for RNA expression profiling analyses. Close to genomewide microarrays were used for identification of changes in gene expression levels in kidney of 4 MFP2-/- mice. Individual mutant mice were hybridised in repetitions against a pool of 5 reference animals. In total 16 chip hybridisations were performed including 50% dye swap experiments.

Mutations in BCKD-kinase lead to a potentially treatable form of autism with epilepsy

Project description:Autism is present in 1% of the population, yet treatments are extremely limited. We identified homozygous inactivating mutations in the BCKDK gene in families presenting with autism and epilepsy. The encoded branched chain ketoacid dehydrogenase kinase protein is responsible for phosphorylation-mediated inactivation of the E1-alpha subunit of branched chain ketoacid dehydrogenase, itself mutated in Maple Syrup Urine Disease (MSUD). Patients with homozygous BCKDK mutations display reductions in BCKDK mRNA and protein, E1-alpha phosphorylation and serum branched chain amino acids (BCAAs). Bckdk knockout mice show abnormal brain amino acids profiles and neurobehavioral defects, which are largely corrected by dietary BCAA supplementation. Thus autism presenting with epilepsy due to BCKDK mutations represent a new and potentially treatable disease.

Effect of FadR overexpression in an engineered fatty acid overproducer

Project description:Transcriptome analysis of strains LT-ΔfadE (control) and FRT-ΔfadE (FadR overexpressor) after 12h of fatty acid production. The strains used are described in detail in Zhang F, M Ouellet, TS Batth, CJ Petzold, A Mukhopadhyay and JD Keasling. Enhancing fatty acid production by the expression of the regulatory transcription factor FadR. (In preparation) Three independent cultures of control strain LT-ΔfadE and four independent cultures of FadR overexpressor strain FRT-ΔfadE were induced. One sample derived from each culture was hybridized.
