Cold-inducible RNA-binding protein (CIRP), released into the circulation during sepsis, causes lung injury via an as yet unknown mechanism. Since endoplasmic reticulum (ER) stress is associated with acute lung injury (ALI), we hypothesized that CIRP causes ALI via induction of ER stress. To test this hypothesis, we studied the lungs of wild-type (WT) and CIRP knockout (KO) mice at 20 h after in...

Embryonic stem cells are immortalized cells whose proliferation rate is comparable to that of carcinogenic cells. To study the expression of embryonic stem cell genes in primary cells, genetic screening was performed by infecting mouse embryonic fibroblasts (MEFs) with a cDNA library from embryonic stem cells. Cold-inducible RNA-binding protein (CIRP) was identified due to its ability to bypass...

The telomerase is responsible for adding telomeric repeats to chromosomal ends and consists of the reverse transcriptase TERT and the RNA subunit TERC. The expression and activity of the telomerase are tightly regulated, and aberrant activation of the telomerase has been observed in >85% of human cancers. To better understand telomerase regulation, we performed immunoprecipitations coupled with...

• A Multi-Vehicle Cyclic Inventory Routing Problem (MV-CIRP) is studied. MV-CIRP the extension of Single-Vehicle CIRP (SV-CIRP). mixed integer nonlinear programming model formulated. Simulated Annealing algorithm proposed to solve both SV-CIRP and MV-CIRP. This paper presents a new variant which aims determine subset customers be visited, appropriate number vehicles used, corresponding cycle ti...

Most hepatocellular carcinomas (HCCs) develop in the context of chronic liver inflammation. Oxidative stress is thought to play a major role in the pathogenesis of HCC development. In this study, we examined whether cold-inducible RNA-binding protein (Cirp) controls reactive oxygen species (ROS) accumulation and development of HCC by using murine models of hepatocarcinogenesis and human liver s...

In response to low ambient temperature, mammalian cells as well as microorganisms change various physiological functions, but the molecular mechanisms underlying these adaptations are just beginning to be understood. We report here the isolation of a mouse cold-inducible RNA-binding protein (cirp) cDNA and investigation of its role in cold-stress response of mammalian cells. The cirp cDNA encod...

PURPOSE To investigate the protective effect of overexpression of cold-inducible RNA-binding protein (CIRP) on testicular damage induced by cryptorchidism. METHODS Male BALB/c mice were made surgically cryptorchid and CIRP gene was transferred into the cryptorchid testis by in vivo electroporation. Seven or ten days after electroporation, the expression of CIRP, p53 and Fas mRNA and protein w...

The transcriptional regulation of several dozen genes in response to low oxygen tension is mediated by hypoxia-inducible factor 1 (HIF-1), a heterodimeric protein composed of two subunits, HIF-1alpha and HIF-1beta. In the HIF-1alpha-deficient human leukemic cell line, Z-33, exposed to mild (8% O(2)) or severe (1% O(2)) hypoxia, we found significant upregulation of two related heterogenous nucle...

Chronic or non-healing wounds are a major concern in clinical practice and these wounds are mostly associated with diabetes, and venous and pressure ulcers. Wound healing is a complex process involving overlapping phases and the primary phase in this complex cascade is the inflammatory state. While inflammation is necessary for wound healing, a prolonged inflammatory phase leads to impaired hea...

Cold-inducible RNA-binding protein (CIRP) is a damage-associated molecular pattern (DAMP) molecule which stimulates proinflammatory cytokine release in hemorrhage and sepsis. Under these medical conditions, disruption of endothelial homeostasis and barrier integrity, typically induced by proinflammatory cytokines, is an important factor contributing to morbidity and mortality. However, the role...
