UNLABELLED Retroviral vectors have been used in successful gene therapies. However, in some patients, insertional mutagenesis led to leukemia or myelodysplasia. Both the strong promoter/enhancer elements in the long terminal repeats (LTRs) of murine leukemia virus (MLV)-based vectors and the vector-specific integration site preferences played an important(More)
p190RhoGAP (p190), a Rho family GTPase-activating protein, regulates actin stress fiber dynamics via hydrolysis of Rho-GTP. Recent data suggest that p190 also regulates cell proliferation. To gain insights into the cellular process(es) affected by p190, we altered its levels by conditional or transient overexpression. Overexpression of p190 resulted in a(More)
Salinomycin is perhaps the first promising compound that was discovered through high throughput screening in cancer stem cells. This novel agent can selectively eliminate breast and other cancer stem cells, though the mechanism of action remains unclear. In this study, we found that salinomycin induced autophagy in human non-small cell lung cancer (NSCLC)(More)
The plant-specific LBD (LATERAL ORGAN BOUNDARIES domain) genes belong to a major family of transcription factor that encode a zinc finger-like domain. It has been shown that LBD genes play crucial roles in the growth and development of Arabidopsis and other plant species. However, no detailed information concerning this family is available for apple. In the(More)
Metastasis of squamous cell carcinoma of the head and neck (SCCHN) is a significant health-care problem worldwide. The 5-year survival rate is less than 50% for patients with lymph node metastases. Understanding the molecular basis of SCCHN metastasis would facilitate the development of new therapeutic approaches to the disease. To identify proteins that(More)
Sirtuins (a class III histone deacetylase) have emerged as novel targets for cancer therapy. Salermide, a reverse amide compound that inhibits Sirtuin 1 (Sirt1) and Sirtuin 2 (Sirt2), has been shown to induce apoptosis in human cancer cells. The mechanism underlying cellular apoptotic signalling by salermide remains unclear. In this study, we show that(More)
BACKGROUND Several members of the zinc finger protein family have been recently shown to have a role in cancer initiation and progression. Zinc finger protein 367 (ZNF367) is a member of the zinc finger protein family and is expressed in embryonic or fetal erythroid tissue but is absent in normal adult tissue. METHODOLOGY/PRINCIPAL FINDINGS We show that(More)
In recent years, the men who have sex with men (MSM) population has seen the fastest growing prevalence of HIV transmission in China. In addition, coinfection through sex and intravenous drug use is a major problem in HIV prevention and control. Recent studies have also revealed that three major viral strains (CRF07_BC, CRF01_AE, and subtype B) have been(More)
PS-341 (bortezomib), a proteasome inhibitor, has been approved for the treatment ofmultiplemyeloma.Our previous work has shown that PS-341 induces death receptor 5 (DR5)–dependent apoptosis and enhances the TNF-related apoptosis-inducing ligand–induced apoptosis in human non–small cell lung cancer cells. However, the definite mechanism remains undefined. In(More)
TNFRSF10A and TNFRSF10B are cell surface receptors that bind to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and mediate the extrinsic pathway of apoptosis. However, the mechanisms of transcriptional regulation of TNFRSF10A and TNFRSF10B remain largely uncharacterized. In this study, two putative DDIT3 binding sites (-1636/-1625;(More)
