The expression of hypoxia-inducible factor-1 (HIF-1) correlates with poor clinical outcomes and confers resistance to the apoptosis of the tumor cells that are exposed to hypoxia. Presently, the mechanism underlying this phenomenon is poorly understood. In this study we provide evidence that transglutaminase 2 (TG2), an enzyme that catalyses protein(More)
In order to achieve highly mineralized tooth enamel, enamel proteinases serve the important function of removing the remaining organic matrix in the mineralization and maturation of the enamel matrix. Mutations in the kallikrein 4 (KLK4), enamelysin (MMP20), and WDR72 genes have been identified as causing hypomaturation enamel defects in an(More)
Microglial responses to endotoxin, including the synthesis of inflammatory factors, contribute to gliosis and neuron degeneration in cultured brain tissue. We have previously shown that Gö6976, a protein kinase C (PKC) inhibitor, suppressed the lipopolysaccharide (LPS)-induced production of inflammatory factors in microglia and afforded marked protection of(More)
For the production of α-D-glucose-1-phosphate (G-1-P), α-1,4-D-glucan phosphorylase from Thermus caldophilus GK24 was partially purified to a specific activity of 13 U mg−1 and an enzyme recovery of 15%. The amount of G-1-P reached maximum (18%) when soluble starch was used as substrate, and the smallest substrate for G-1-P formation was maltotriose. The(More)
The current study was carried out to define the involvement of Peroxiredoxin (Prx) II in progression of hepatocellular carcinoma (HCC) and the underlying molecular mechanism(s). Expression and function of Prx II in HCC was determined using H-ras(G12V)-transformed HCC cells (H-ras(G12V)-HCC cells) and the tumor livers from H-ras(G12V)-transgenic (Tg) mice(More)
BACKGROUND Werner protein (WRN) has DNA helicase activity and participates in recombination, replication and repair of DNA. Loss-of-function mutations in WRN gives rise to genetic instability and diseases such as premature ageing and cancer. Upregulation of WRN promotes proliferation and survival of cancer cells. AIM To evaluate the expression pattern of(More)
BACKGROUND AND OBJECTIVE The predictability of conventional periodontal treatments for damaged periodontal tissue is limited, particularly on the regeneration of new cementum. As signaling molecules, a range of growth factors has been used to promote periodontal regeneration on periodontal ligament (PDL) and cementum defects. A preameloblast-conditioned(More)
