Abstract

We investigated gender difference in the effects of chronic exposure to human growth hormone (hGH) on cardiac risk biomarkers using transgenic mice with non-pulsatile circulating hGH. Blood plasma was obtained from transgenic and control mice at 8, 12, and 16 weeks of age, and was used for the measurement of hGH and the following cardiac risk biomarkers: total cholesterol (CHO), triglyceride (TG), HDL cholesterol (HDL), LDL cholesterol (LDL), non esterified free fatty acids (NEFA), and lipid peroxides (LPO). The hearts and the livers of transgenic mice were weighed and histopathologically examined, and the results were compared with those of control mice. Transgenic males exhibited higher levels of LDL at 8 and 12 weeks of age and higher levels of LPO at every week of age examined, as compared to those of the control males, while transgenic females exhibited somewhat lower levels of LDL and LPO from 8 to 16 weeks of age, as compared to the control females. The relative heart weight in males increased with aging and was significantly higher in the 16-week-old transgenic males compared to those of the control mice. The present results demonstrate that transgenic males had cardiac risk potential caused by chronic-exposure to hGH a...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
