Ischemia/reperfusion is a major cause of acute kidney injury and can induce apoptosis in renal epithelial tubule (HK-2) cells. Accumulating evidence indicates that endoplasmic reticulum (ER) stress is a major contributor to apoptosis in acute kidney injury. We previously reported that augmenter of liver regeneration (ALR) functions as an anti-apoptotic factor in H2O2-treated HK-2 cells although the...
CCAAT enhancer binding protein-α (C/EBP-α) is a transcript factor that regulates adipocyte differentiation and induces apoptosis in hepatic stellate cells (HSCs) in vivo and in vitro. However, the effect of C/EBP-α on hepatocytes in vivo remains unknown. This study investigated whether C/EBP-α exerts different apoptotic effects on hepatocytes and HSCs in vitro and in vivo. An adenovirus vector-expressing...
Human papillomavirus (HPV) E2 gene disruption is one of the key features of HPV-induced cervical malignant transformation. Though it is thought to prevent progression of carcinogenesis, the pro-apoptotic function of E2 protein remains poorly understood. This study shows that expression of HPV16 E2 induces apoptosis both in HPV-positive and -negative cervical cancer cell lines and leads to hyperactivation...
Excess apoptosis of endothelial cells (EC) plays crucial roles in the onset and progression of vasculopathy in diabetes mellitus. Anion exchanger-2 (AE2) might be involved in the vasculopathy. However, little is known about the molecular mechanisms that AE2 mediated the apoptosis of EC. The purpose of this study was to explore the role of AE2 in the apoptosis of HUVECs induced by high glucose (HG)...
Paclitaxel (Taxol™) is a microtubule-interfering agent that induced persistent and transient G2/M arrest before apoptosis in human nasopharyngeal carcinoma (NPC) cells at high and low concentrations, respectively. In this study, we intended to explore the underlying molecular events and found that cellular cyclin B1/CDC 2 kinase activity was increased and persisted for >6 h upon paclitaxel treatment...
