ABSTRACT
OBJECTIVE:
To explore ANGPTL4 expressions in patients with gestational diabetes mellitus (GDM) and its underlying mechanism. PATIENTS ANDMETHODS:
We first detected serum expressions of ANGPTL4 in GDM patients and healthy pregnancies. Subsequently, effects of ANGPTL4 knockdown on apoptosis, proliferation, and cell cycle in 3T3-L1 cells were determined, respectively. Effects of ANGPTL4 on glucose uptake and adipocyte differentiation were also evaluated, respectively. The cytokine secretion in adipocytes transfected with sh-ANGPTL4 was detected by quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Furthermore, effects of ANGPTL4 knockdown on NF-kB and Akt pathway were detected by Western blot.RESULTS:
ANGPTL4 was down-regulated in serum of GDM patients. In vitro experiments suggested that down-regulated ANGPTL4 inhibited apoptosis and promoted proliferation of 3T3-L1 cells. Meanwhile, down-regulated ANGPTL4 significantly inhibited glucose uptake and Akt pathway. However, ANGPTL4 expression did not affect cell cycle and adipocyte differentiation. Detection of inflammatory cytokines suggested that down-regulated ANGPTL4 resulted in increased expressions of inflammatory cytokines and activation of NF-kB pathway.CONCLUSIONS:
ANGPTL4 is down-regulated in GDM and may participate in the GDM development by promoting insulin resistance and secretion of inflammatory cytokines.
