Our previous studies have demonstrated that bone morphogenetic protein 9 (BMP-9) is one of the most efficacious BMPs to induce osteoblast differentiation of mesenchymal stem cells (MSCs). However, the molecular mechanism underlying the BMP-9-induced osteogenic differentiation of MSCs remains to be fully elucidated. In this study, dominant negative (DN) type(More)
RNase E functions as the rate-limiting enzyme in the global mRNA metabolism as well as in the maturation of functional RNAs. The endoribonuclease, binding to the PNPase trimer, the RhlB monomer, and the enolase dimer, assembles into an RNA degradosome necessary for effective RNA metabolism. The RNase E processing is found to be negatively regulated by the(More)
Progranulin (PGRN) is a multi-functional protein known to be involved in inflammation. Recent studies have found that PGRN has dual roles in inflammation and exerts anti-inflammatory and pro-inflammatory function in different diseases. However, the role of PGRN in psoriasis has not been fully elucidated. Here, we detected preferential expression of PGRN in(More)
Pneumococcal polysaccharide-based vaccines are effective in preventing pneumococcus infection; however, some drawbacks preclude their widespread use in developing and undeveloped countries. Here, we evaluated the protective effects of ATP-dependent caseinolytic protease (ClpP), pneumolysin mutant (DeltaA146 Ply), putative lipoate-protein ligase (Lpl), or(More)
Interleukin (IL)-27 is a member of IL-6/IL-12 family cytokines produced by antigen-presenting cells in immune responses. IL-27 can drive the commitment of naive T cells to a T helper type 1 (Th1) phenotype and inhibit inflammation in later phases of infection. Human bronchial epithelial cells have been shown to express IL-27 receptor complex. In this study,(More)
Pneumolysin (Ply) and its variants are protective against pneumococcal infections in animal models, and as a Toll-like receptor 4 agonist, pneumolysin has been reported to be a mucosal adjuvant. DnaJ has been approved as a useful candidate vaccine protein; we therefore designed novel fusion proteins of DnaJ with a form of Ply that has a deletion of A146(More)
Heat shock proteins (HSPs) play important roles in the pathogenesis of pneumococcal infection, and they are considered as potential protein vaccine antigens. In this study, we investigated the efficacy of immunization with pneumococcal HSPs, including ClpP (hsp100/Clp peptidase subunit), DnaJ (hsp40) and GroEL (hsp60), to protect against pneumococcal(More)
Increasing mortality, morbidity and economic costs have been paid to pneumococcal diseases every year. Currently, vaccination is the most promising strategy to reduce the occurrence of pneumococcal infection. In this study, we investigated the protective efficacy of immunization with recombinant DnaJ (hsp40) protein against infections of different serotypes(More)
Prostate cancer (PCa) is the second most common cancer in men, and its incidence is still increasing. PCA3 is the most prostate cancer specific biomarker. Here we confirmed that both exon 3 and exon 4 are in the prostate-specific region of the PCA3 gene, and established the methodology of real-time fluorescent quantitative RT-PCR (FQ-RT-PCR) detecting PCA3(More)
Zinc metalloprotease B (ZmpB) is present in all isolated pneumococcal strains and contributes to the pathogenesis of pneumococcal infection. In this study, recombinant ZmpB was cloned and expressed in Escherichia coli. The expression of ZmpB by different pneumococcal strains was detectable by Western blotting with antisera raised to recombinant ZmpB. Flow(More)
