Objective: To study the effect of grape procyanidins (GPC) on the expressions of Caspase-3 and Bax in the liver of mice with ethanol-induced liver injury.
Method: The mice were orally given at the different doses of GPC (50,100 and 200 mg/kg) and 4 g/kg ethanol, and killed after 4 weeks. The proliferation activity of the hepatic cells was determined by MTT assay,the levels of Caspase-3 and Bax protein expression in the cells were measured by immunohistochemistry method.
Results: The expression level of Caspase-3 and Bax protein in high dose group were 19.08% and 14.06%, respectively, and those of the ethanol-injured group were 51.78% and 58.08%. The differences between the two groups were significant (P < 0.05). The cell proliferation activity of high dose and medium dose group was higher than the cell proliferation activity of ethanol-injured group (P < 0.05).
Conclusion: GPC could suppressing the expression of Caspase-3 and Bax in the liver of mice with ethanol-induced liver injury.

Ischemia-reperfusion injury (IRI) is a common pathogenic situation that arises throughout all liver surgeries, including liver transplants. We aimed to compare the preventive effects of valsartan (VST) against valsartan + sacubitril (LCZ696) on hepatic injury caused by IRI. A total of thirty-six male Westar albino rats were split into six groups randomly: sham, IRI, VST + IRI, LCZ696 + IRI, VST, and LCZ696.

Objective: Polycystic ovary syndrome (PCOS) is a diverse condition with an unknown cause. The precise mechanism underlying ovulatory abnormalities in PCOS remains unclear. It is widely believed that malfunction of granulosa cells is the primary factor contributing to aberrant follicular formation in PCOS.

The vascular endothelial growth factor receptor is essential for the angiogenesis of cancer. Tumor propagation was effectively suppressed by inhibiting VEGFR-2 activity. As a result, the target quinoxaline-pyrazole hybrids were created in a way that closely resembled the structural characteristics of VEGFR-2 inhibitors.

Callistephus chinensis Nees is an herbaceous plant in the Asteraceae family that has various traditional effects, especially in preventing liver disease. Callistephus A (CA) is a sesquiterpene compound with a rare 6/7 ring skeleton, which has been isolated only from the Callistephus chinensis Nees, but whether CA protects the liver is unknown. Immunological liver injury (ILI) is a common liver disease mediated by the immune system.

Cardiotoxic effect of Doxorubicin (Dox) limits its clinical application. Previously, we reported that Dox induces phosphorylation of lamin A/C (pS22 lamin A/C), increased nuclear size, damage to the nuclear membrane, and cell death. However, the activation of signalling pathway during this event remains elusive, and it is unclear whether increased phospho-lamin A/C activates the cell death pathway in heart.
