Glucagon-like peptide-1 protects against cardiac microvascular endothelial cells injured by high glucose.

Objective: To investigate the protective effect of glucagon-like peptid-1 (GLP-1) against cardiac microvascular endothelial cell (CMECs) injured by high glucose.

Methods: CMECs were isolated and cultured. Superoxide assay kit and dihydroethidine (DHE) staining were used to assess oxidative stress.

The effects of subclinical hypothyroidism on serum lipid level and TLR4 expression of monocyte in peripheral blood of rats.

Objective: To observe effect of subclinical hypothyroidism (SCH) on serum lipid level and expression of toll-like receptor 4 (TLR4) in rats' peripheral blood mononuclear cells (PBMC).

Methods: Fifty Wistar female rats were divided into three groups: normal control (NC group; n=10), sham group (n=10), and L-T-4 (L-thyroxine) group (n=30, with thyroidectomy, fed with rich-calcium water after operation. 5 weeks later, abdominal subcutaneous injection of L-T-4: 0.

Atorvastatin decreases Toll-like receptor 4 expression and downstream signaling in human monocytic leukemia cells.

Purpose: We aim to evaluate the effects of atorvastatin on the expression of Toll-like receptor (TLR4) protein and mRNA, and to explore their effects on TLR4-dependent downstream signaling in human monocytic leukemia (THP-1) cells.

Methods: TLR4 protein and mRNA expression, levels of NF-κB protein, and expression of TNF-α, IL-6, and IL-1β in lipopolysaccharide-induced THP-1 cells after incubation with different concentrations of atorvastatin (0.1, 1, 10, 20μM) were quantified via flow-cytometry, quantitative RT-PCR, western blotting, and ELSIA kits.
