Rapid induction of type I interferon expression, a central event in establishing the innate antiviral response, requires cooperative activation of numerous transcription factors. Although signaling pathways that activate the transcription factors nuclear factor kappaB and ATF-2/c-Jun have been well characterized, activation of the interferon regulatory(More)
BACKGROUND Studies have shown that lipoxin A(4) (LXA(4)) and its analogues inhibited proliferation of glomerular mesangial cells induced by leukotriene D(4) (LTD(4)) or platelet-derived growth factor (PDGF), reduced the production of proinflammatory cytokines such as interleukin (IL)-1beta and IL-6 in renal tissue of ischemic injury. In the present studies,(More)
Interferon regulatory factor 3 (IRF-3), an essential transcriptional regulator of the interferon genes, plays an important role in host defense against viral and microbial infection as well as in cell growth regulation. Promoter plays a crucial role in gene transcription. We have reported the characterization of the wide type of human IRF-3 promoter, but(More)
The human CD2-associated protein (CD2AP) is involved in several molecular signaling pathways and is an important factor responsible for nephrotic syndrome. Here we report the identification of the transcription start point and promoter region of the human CD2AP gene in renal tubular epithelial cells. With luciferase assays and deletion analysis, we found(More)
Interferon regulatory factor 3 (IRF-3) plays an important role in virus and double-stranded RNA-mediated induction of type I interferon and RANTES, DNA damage signaling, tumor suppression, and virus-induced apoptosis. However, cis elements or trans factors responsible for regulating IRF-3 expression remain largely unknown. Here we report that the(More)
OBJECTIVES Bladder cancer is the most common type of urologic cancer in Chinese males. The 5-year survival rate of advanced bladder cancer is approximately 20%-40%. There is an obvious urgent need for novel and effective therapies against bladder cancer. MicroRNAs (miRNAs) are a recently discovered class of noncoding RNAs; suppressing miRNA-221 might prove(More)
RhoBTB2, or Deleted in Breast Cancer 2 (DBC2), identified as a candidate tumor suppressor gene for breast cancer and other human malignancies, is an atypical member of a novel gene family encoding small GTPases. In this study, we found that ectopic expression of RhoBTB2 inhibits the migration and invasion of the human metastatic breast cancer cell lines(More)
The CD2 associated protein (CD2AP) is characterized as a T-lymphocyte CD2 adapter protein and is found to be related to glomerulosclerosis, and CD2AP knockout mice develop a rapid onset nephrotic syndrome and die of renal failure. Here we report that the transcription factor Sp1 and Sp3 up-regulate the basal transcriptional activity of CD2AP and increase(More)
BACKGROUND Oxidative stress is an important inducer of cell apoptosis and plays a key role in the development of renal inflammation. The prostate apoptosis response factor-4 (Par-4) gene was originally identified in prostate cells undergoing apoptosis. Subsequently, Par-4 was found to possess potent pro-apoptotic activity in various cellular systems.(More)
OBJECTIVE The KCl cotransporter (KCC) plays an important role in cellular cation and volume regulation and contributes to the process of volume reduction that accompanies reticulocyte maturation. In human red cells containing sickle hemoglobin, KCl cotransporter activity is high compared to normal cells, and contributes to the deleterious dehydration of(More)
