Genetic association of long-chain acyl-CoA synthetase 1 variants with fasting glucose, diabetes, and subclinical atherosclerosis

Genetic association of long-chain acyl-CoA synthetase 1 variants with fasting glucose, diabetes, and subclinical atherosclerosis.

Long-chain acyl-CoA synthetase 1 (ACSL1) converts free fatty acids into acyl-CoAs. Mouse studies have revealed that ACSL1 channels acyl-CoAs to β-oxidation, thereby reducing glucose utilization, and is required for diabetes-accelerated atherosclerosis. The role of ACSL1 in humans is unknown. We therefore examined common variants in the human ACSL1 locus by genetic association studies for fastin...

Structure and regulation of rat long-chain acyl-CoA synthetase.

Complementary DNAs encoding rat long-chain acyl-CoA synthetase have been isolated. The cDNAs were identified using synthetic oligonucleotide probes based on partial amino acid sequences of lysyl endopeptidase peptides of the purified enzyme. Rat long-chain acyl-CoA synthetase is predicted to contain 699 amino acid residues and to have a calculated molecular weight of 78,177. Significant sequenc...

Association of a Fasting Glucose Genetic Risk Score With Subclinical Atherosclerosis

OBJECTIVE Elevated fasting glucose level is associated with increased carotid intima-media thickness (IMT), a measure of subclinical atherosclerosis. It is unclear if this association is causal. Using the principle of Mendelian randomization, we sought to explore the causal association between circulating glucose and IMT by examining the association of a genetic risk score with IMT. RESEARCH ...

Functional analysis of long-chain acyl-CoA synthetase 1 in 3T3-L1 adipocytes.

ACSL1 (acyl-CoA synthetase 1), the major acyl-CoA synthetase of adipocytes, has been proposed to function in adipocytes as mediating free fatty acid influx, esterification, and storage as triglyceride. To test this hypothesis, ACSL1 was stably silenced (knockdown (kd)) in 3T3-L1 cells, differentiated into adipocytes, and evaluated for changes in lipid metabolism. Surprisingly, ACSL1-silenced ad...
