BMI and insulin levels impact serum sOb-R.
摘要
Abstract and Introduction:
- sOb-R may protect against diabetes.
- Study combines various designs.
- sOb-R inversely related to BMI, body fat, and fasting C-peptide.
- Response to insulin, exercise, and food intake.
- Mendelian randomization shows causal links.
- Hyperglycemia's effect on sOb-R inconsistent.
Introduction:
- Leptin's role in various bodily functions.
- sOb-R reflects membrane-bound Ob-Rs.
- sOb-R levels inversely related to adiposity.
- High sOb-R linked to lower diabetes risk.
- Regulation of sOb-R remains unclear.
統計資料
In pooled data, sOb-R inversely associated with BMI, body fat, and fasting C-peptide.
sOb-R decreased in response to hyperinsulinemia and increased with exercise and food intake.
Higher fasting insulin and BMI causally linked to lower sOb-R levels.
引述
"BMI and insulin both causally decreased serum sOb-R levels."
"Our results suggest that sOb-R is involved in short-term regulation of leptin signaling."
"Leptin levels are severely increased in obesity, but appetite inhibition fails, probably due to leptin resistance."
