MAPK phosphatase-1 (MKP-1) is an archetypical member of the dual-specificity phosphatase family that deactivates MAPKs. Induction of MKP-1 has been implicated in attenuating the LPS- or peptidoglycan-induced biosynthesis of proinflammatory cytokines, but the role of noncoding RNA in the expression of the MKP-1 is still poorly understood. In this study, we(More)
Kaposi's sarcoma-associated herpesvirus (KSHV) is the major biological cofactor contributing to development of Kaposi's sarcoma. KSHV establishes a latent infection in human B cells expressing the latency-associated nuclear antigen (LANA), a critical factor in the regulation of viral latency. LANA controls KSHV latent infection through repression of RTA, an(More)
Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiological agent contributing to development of Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman desease. Following primary infection, latency is typically established. However, the mechanism by which KSHV establishes latency is not understood. We have reported that the(More)
Cytoskeleton rearrangement is necessary for tumor invasion and metastasis. Cellular molecules whose role is to regulate components of the cytoskeletal structure can dictate changes in cellular morphology. One of these molecules is the suppressor of tumor metastasis Nm23-H1. The level of Nm23-H1 expression has been linked to the invasiveness and metastatic(More)
Tumor invasion and metastasis is regulated by a number of cellular molecules known to be involved in signaling and cytoskeletal rearrangement. One of these molecules is the suppressor of tumor metastasis Nm23-H1 which linked to invasiveness and metastatic potential of human cancers. Nm23-H1 expression is down-regulated in human melanoma and invasive breast(More)
Epstein-Barr virus (EBV) nuclear antigen 3C (EBNA3C) is a known regulatory transcription factor that has been shown to interact with histone deacetylase 1 (HDAC1) when cotransfected in human cell lines and by in vitro binding experiments. Previous studies have shown that EBNA3C interacts with p300 and prothymosin alpha (ProTalpha) in EBV-infected cells and(More)
Seventeen miRNAs encoded by Kaposi's sarcoma-associated herpesvirus (KSHV) have been identified and their functions have begun to be characterized. Among these miRNAs, we report here that miR-K12-7 directly targets the replication and transcription activator (RTA) encoded by open reading frame 50. We found that miR-K12-7 targeted the RTA 3' untranslated(More)
Kaposi's sarcoma-associated herpesvirus (KSHV/HHV8) displays two life modes, latency and lytic reactivation in the infected host cells which are equally important for virus mediated pathogenesis. During latency only a small number of genes are expressed. Under specific conditions, KSHV can undergo lytic replication with the production of viral progeny. One(More)
Human respiratory syncytial virus (HRSV) of genus Pneumovirus is one of the most common pathogens causing severe acute lower respiratory tract infection in infants and children. No information on the genotype distribution of HRSV is available in East China (e.g. Shanghai). From August 2009 to December 2012, 2407 nasopharyngeal swabs were collected from(More)
Pim kinases are proto-oncogenes that are upregulated in a number of B cell cancers, including Epstein-Barr Virus (EBV) associated Burkitt's lymphoma. They have also been shown to be upregulated in Kaposi sarcoma-associated herpes virus (KSHV) infected primary B cells. Most cells in KSHV-associated tumors are latently infected and express only a small subset(More)
