REG Iα gene expression is linked with the poor prognosis of lung adenocarcinoma and squamous cell carcinoma patients via discrete mechanisms.

The aim of the present study was to evaluate the effects of the REG Iα and REG Iβ genes on lung cancer cell lines, and thereafter, the expression of REG family genes (REG Iα, REG Iβ, REG III, HIP/PAP and REG IV) in lung cancer in relation to patient prognosis was evaluated. Lung adenocarcinoma (AD) and squamous cell carcinoma (SCC) cell lines expressing REG Iα or REG Iβ (HLC-1 REG Iα/Iβ and EBC-1 REG Iα/Iβ) were established, and cell number, cell invasive activity, and anchorage-independent cell growth were compared with these variables in the control cells. The expression levels of REG family genes were evaluated by real-time RT-PCR in surgically resected lung cancers, and disease-specific survival (DSS) curves were generated.

Pancreatic β cell proliferation by intermittent hypoxia via up-regulation of Reg family genes and HGF gene.

Aims: Although accumulating evidence suggests the associations between sleep apnea syndrome (SAS) and type 2 diabetes, the direct effect of intermittent hypoxia (IH) on pancreatic β cell proliferation remains a missing piece of the puzzle.

Main Methods: Rat RINm5F β cells, hamster HIT-T15 β cells, and human 1.1B4 β cells were exposed to normoxia (21% O2, 5% CO2, and balance N2), to sustained hypoxia (SH: 1% O2, 5% CO2, and balance N2), or to intermittent hypoxia (IH: 64 cycles of 5 min SH and 10 min normoxia) for 24 h.

Genomic organization, chromosomal localization, and promoter of human gene for FK506-binding protein 12.6.

Cyclic ADP-ribose (cADPR) induces the release of Ca2+ from microsomes of pancreatic islets for insulin secretion. It has been demonstrated that cADPR binds to FK506-binding protein 12.6 (FKBP 12.

Up-regulation of cyr61 in vascular smooth muscle cells of spontaneously hypertensive rats.

In the present study, we applied a fluorescent differential display method to mRNAs from aortae of spontaneously hypertensive rats (SHRs), stroke-prone spontaneously hypertensive rats (SPSHRs), and their parental strain, Wistar Kyoto rats (WKYRs), to identify the genes involved in the development of hypertension. Through this screen we came across a gene that is consistently up-regulated in hypertensive rats. Nucleotide sequence determination of the corresponding cDNA revealed that the gene is the rat orthologue of cyr61.
