The spindle checkpoint senses unattached or improperly attached kinetochores during mitosis, inhibits the anaphase-promoting complex or cyclosome (APC/C), and delays anaphase onset to prevent aneuploidy. The mitotic checkpoint complex (MCC) consisting of BubR1, Bub3, Mad2, and Cdc20 is a critical APC/C-inhibitory checkpoint complex in human cells. At the(More)
Recent evidence suggests that fibrocystin/polyductin (FPC), polycystin-1 (PC1), and polycystin-2 (PC2) are all localized at the plasma membrane and the primary cilium, where PC1 and PC2 contribute to fluid flow sensation and may function in the same mechanotransduction pathways. To further define the exact subcellular localization of FPC, the protein(More)
Recent evidence suggests that structural and functional abnormalities of primary cilia in kidney epithelia are associated with mouse and human autosomal dominant polycystic kidney disease. To determine whether fibrocystin/polyductin/tigmin (FPC), the protein product encoded by the PKHD1 gene that is responsible for autosomal recessive polycystic kidney(More)
In kidneys, each tubular epithelial cell contains a primary cilium that protrudes from the apical surface. Ciliary dysfunction was recently linked to acute kidney injury (AKI) following renal ischemia-reperfusion. Whether ciliary regulation is a general pathogenic mechanism in AKI remains unclear. Moreover, the ciliary change during AKI and its underlying(More)
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(More)
Human papillomavirus (HPV) integration is a key genetic event in cervical carcinogenesis. By conducting whole-genome sequencing and high-throughput viral integration detection, we identified 3,667 HPV integration breakpoints in 26 cervical intraepithelial neoplasias, 104 cervical carcinomas and five cell lines. Beyond recalculating frequencies for the(More)
OBJECTIVE Neoadjuvant chemotherapy (NACT) for cervical cancer still remains controversial. NACT was evaluated to establish selection criteria. METHODS A matched-case comparison was designed for the NACT group (n=707) and primary surgery treatment (PST; n=707) group to investigate short-term responses and high/intermediate risk factors (HRFs/IRFs). The(More)
The aim of the present study was to investigate the role of Stat3 in cisplatin resistant ovarian cancer. It was first demonstrated that higher activated Stat3 was detected in cisplatin-resistant ovarian cancer cell lines. To provide evidence that supported the hypothesis that phosphorylated-Stat3 expression may promote cisplatin resistance, ectopic Stat3(More)
Chronic hypoxia in the renal parenchyma is thought to induce epithelial-to-mesenchymal transition (EMT), leading to fibrogenesis and ultimately end-stage renal failure. Biliverdin reductase, recently identified as a serine/threonine/tyrosine kinase that may activate phosphatidylinositol 3-kinase (PI3K) and Akt, is upregulated in response to reactive oxygen(More)
Plasma membrane potassium (K+) channels are required for tumor cell proliferation and apoptosis. However, the signal transduction mechanisms underlying K+ channel-dependent tumor cell proliferation or apoptosis remains elusive. Using HeLa and A2780 cells as study models, we tested the hypothesis that apoptotic proteins are linked with K+ channel-dependent(More)
