Abstract

To explore the possible mechanism of placental dysfunction in patients with intrahepatic cholestasis of pregnancy (ICP). Serum level of cholylglycine (CG) in 30 cases with ICP (ICP group) and 27 normal pregnant women (control group) was examined by radio-immunoassay before delivery. bax and bcl-2 level in placenta was detected by immunohistochemistry method. (1) Serum CG level in ICP group was (51.8 +/- 5.9) micro mol/L, and in control group it was (9.4 +/- 5.6) micro mol/L. The difference between the two groups was significant (P < 0.05). (2) bax expression level in syncytiotrophoblast of ICP group was: 2(-), 9(+), 11 (++), 8(+++), and bcl-2 expression level was: 12(+), 12(++), 6(+++); bax expression level in control group was: 9 (-), 13(+), 4(++), 1(+++) and bcl-2 expression level was: 3(+), 4(++), 20(+++). bax expression level in syncytiotrophoblast of ICP group was higher than that of the control (P < 0.0005), and bcl-2 expression level was lower than in the control (P < 0.0005), both significantly. A significant positive correlation between CG level and bax expression level and a negative correlation between CG and bcl-2 were found in ICP group (P < 0.005, P < 0.005). One of the possible mechanisms involved in placental dy...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.
