Objective To study the expressions of Cycteine aspartate-specific protease-3(Caspase-3) and human telomerase reverse transcriptase(hTERT) in Barrett\'s esophagus(BE) and esophagitis with cardiac gland or fundus gland metaplasia,and to investigate their roles on pathogenesis of Barrett\'s esophagus.

Spectrophotometric method was selected to explore the activity of caspase-3.

Objective: Investigating the expression of Caspase-3 mRNA by reverse transcription polymerasechain reaction(RT-PCR) in the normal and preeclampsia placentas in order to evaluate the role of Caspase-3 in preeclampsia.

Eventually resistant tumor cells manifest as inhibition of the activation of Caspase-3,and reduction of apoptosis.

To investigate the effect of hydrogen peroxide(H2O2)on the expression of caspase-3 and the changes of ultra-structures in protoscolex cells of Echinococcus granulosus in vitro,the protoscolex cells were cultured in vitro with special RMPI-1640 medium in which glutamine was added.

Caspase-3 Expression in T-24 Bladder Carcinoma Cell after Irradiation by Holmium Laser;

Objective:To observe the changes in caspase3 expression and apoptosis after liver ischemia/reperfusion(I/R),and to clarify whether propofol has a liver protection effect and the possible mechanism.

Objective To study whether apoptin gene induces apoptosis in human melanoma cells A 375 via the activation caspase-8 and caspase-3.

Methods Cell viability was assessed by MTT assay;cell cycle distribution,apoptosis and mitochondrial membrane potential were measured by flow cytometry;the protein expressions of P-gp,caspase-3,caspase-8,caspase-9,p53,Bcl-xL and cytochrome c in the K562/DOX cells were evaluated by Western blot.
