The prognosis of pancreatic cancer is still very poor, how to detect pancreatic cancer from high-risk group in an early stage is essential for improving its long-time survival. Therefore, the purpose of this study was to explore specific biomarkers that can differentiate pancreatic cancer-associated diabetes from type-2 diabetes for the early detection of pancreatic cancer. In the current study, we used global gene transcription analysis with affymetrix gene chip to identify genes specifically expressed in pancreatic cancer-associated diabetes mellitus from peripheral blood samples in stead of from tissue samples.

View SamplesHeat shock proteins are highly conserved proteins that, when produced intracellularly, protect stress exposed cells. It has been suggested that extracellular Hsp70 has both protective and deleterious effects. Our study showed eHSP70 increased the ALP activity, promoted mineralization and up-regulated osteogenesis-related markers.
Extracellular heat shock protein 70 promotes osteogenesis of human mesenchymal stem cells through activation of the ERK signaling pathway.

View SamplesVia aerobic glycolysis-Warnburg effect, cancer cells can convert 85-90% of glucose they acquire to lactic acid, which is thus ubiquitously abundant in solid tumor environment. We also observed that lactic acid effectively rescues cancer cells from glucose staration.

View SamplesIt has been demonstrated that Ring finger protein 43 (RNF43) is overexpressed in colorectal cancer and mediates cancer cell proliferation. We found that RNF43 was frequently overexpressed in HCC, and knockdown of RNF43 could induce apoptosis and inhibit proliferation, invasion, colony formation and xenograft growth of HCC cells. Suggesting that RNF43 is involved in tumorigenesis and progression of HCC.

View SamplesThe widely used white light-emitting diodes (LED) deliver higher levels of blue light than do conventional domestic light sources. The high intensity of blue component is the main source of concern about the health risks of LED with respect to their light-toxicity to the retina. White LED light with higher correlated color temperature (CCT) is more likely to cause retinal injury in mice, significantly reducing the number of ONL nuclei, however apoptosis pathway may not be the only mechanism.

View SamplesThe environmental carcinogen, ()-anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE), causes bulky-adduct DNA damages, triggers certain signaling pathways, and elicits gene expression changes. Here, we focused on the temporal gene expression changes induced by a low concentration (0.05 M) BPDE in human amnion epithelial FL cells. Differential gene expression profiles at 1, 10 and 22 h post BPDE treatment were obtained using Affymetrix HG-U133 Plus 2.0 oligonucleotide microarrays.

View SamplesGenotoxic agents cause cellular DNA damage and stress responses, including transcriptional changes. Here we focused on the early transcriptional responses of human cells to benzo(a)pyrene diol epoxide (BPDE), which causes bulky DNA adduct damage. Human amnion epithelial FL cells were exposed to three doses of BPDE (5, 50, and 500 nM) and the vehicle control DMSO, and differential gene expression profiles were obtained 4 h after exposure using oligonucleotide microarrays followed by validation with quantitative real-time RT-PCR.

View SamplesThe alkylating agent N-methyl-N-nitro-N-nitrosoguanidine (MNNG) induces cellular DNA damages and other comprehensive alterations that lead to chromosomal aberrations, mutations, tumor initiations, and cell death. However, the molecular mechanism of MNNG-induced cellular stress remains unclear.We have genome-wide analyzed early transcriptional responses of human FL amnion epithelial cells after exposure to three relatively low doses of MNNG (0.2, 1.0, and 10.0M),and differential gene expression profiles were obtained 4 h after exposure using oligonucleotide microarrays followed by validation with quantitative real-time RT-PCR.

View SamplesThere is still a big debate about the correlation between melanosis coli (MC) and carcinoma. We used HTA2.0 to investigate the expression changes of lncRNAs and mRNAs in human colonic mucosa with or without MC and try to investigate MC from gene aspect, eventually to demonstrate whether theres a certain correlation between MC and carcinoma.
