The nucleotide sequence of the lspA gene coding for lipoprotein signal peptidase of Escherichia coli was determined and the amino acid sequence of the peptidase was deduced from it. The molecular mass and amino acid composition of the predicted lipoprotein signal peptidase were consistent with those of the signal peptidase purified from cells harboring the lspA gene-carrying plasmid. The peptid...

The present study was carried out to investigate the association of C/T single nucleotide polymorphism(SNP)in exon 5 of stearoyl-CoA desaturase 1 (SCD1) gene and A/C SNP in the 3' untranslated region of oxidized low density lipoprotein receptor 1 (OLR1)gene with milk production traits in Iranian Holstein dairy Cattle. The blood samples of 153 (for OLR1) and 308 (for SCD1) dairy cattle from thre...

background: metabolic syndrome (mets) is a prevalent disorder in pediatric age groups, described by a combination of genetic and environmental factors. sterol regulatory element‑binding transcription factor 1 (srebf‑1) induces the expression of a family of genes involved in fatty acid synthesis. moreover, dysregulation of mir‑33b, which is located within the intron 17 of the srebf‑1 gene, disru...

Outer membrane lipoproteins of Escherichia coli are released from the inner membrane upon the formation of a complex with a periplasmic chaperone, LolA, followed by localization to the outer membrane. In vitro biochemical analyses revealed that the localization of lipoproteins to the outer membrane generally requires an outer membrane lipoprotein, LolB, and occurs via transient formation of a L...

Micro-vascular complications such as diabetic nephropathy (DN) develop in patients with uncontrolled T1DM. Low density lipoprotein receptor-related protein 5 (LRP5) is the co-receptor ligand of Wnt signaling pathway. Many single nucleotide variants have been identified human LRP5 gene and were reported to be associated metabolic disorders. The Wnt/β-catenin pathway has proposed play an importan...

OBJECTIVES The PCSK9 gene, encoding a pro-protein convertase involved in posttranslational degradation of low-density lipoprotein receptor, has emerged as a key regulator of plasma low-density lipoprotein cholesterol. In African-Americans two nonsense mutations resulting in loss of function of PCSK9 are associated with a 30% to 40% reduction of plasma low-density lipoprotein cholesterol. The ai...
