Sepsis represents uncontrolled inflammation due to an infection. Cold-inducible RNA-binding protein (CIRP) is a stress-induced damage-associated molecular pattern (DAMP). A subset of neutrophils expressing ICAM-1+ neutrophils was previously shown to produce high levels of reactive oxygen species. The role of CIRP for the development and function of ICAM-1+ neutrophils during sepsis is unknown. We hypothesize that CIRP induces ICAM-1 expression in neutrophils causing injury to the lungs during sepsis. Using a mouse model of cecal ligation and puncture (CLP)-induced sepsis, we found increased expression of CIRP and higher frequencies and numbers of ICAM-1+ neutrophils in the lungs...

Organisms living in extremely cold environments possess mechanisms to survive low temperatures. Among the known cold-induced genes, cold-shock proteins (Csps) are the most prominent. A csp-homologous gene, cspBPi, has been cloned from the Arctic bacterium Polaribacter irgensii KOPRI 22228, and overexpression of this gene greatly increased the freezing tolerance of its host. This protein consists of a unique N-terminal domain and a well conserved C-terminal cold shock domain. To elucidate the detailed mechanisms involved in the extraordinary freeze-tolerance conferred by CspBPi, we identified the responsible domain by mutational analysis...

RNA binding proteins (RBPs) play key roles in RNA dynamics, including subcellular localization, translational efficiency and metabolism. Cold-inducible RNA binding protein (CIRP) is a stress-induced protein that was initially described as a DNA damage-induced transcript (A18 hnRNP), as well as a cold-shock domain containing cold-stress response protein (CIRBP) that alters the translational efficiency of its target messenger RNAs (mRNAs). This review summarizes recent work on the roles of CIRP in the context of inflammation and cancer...

Cold-inducible RNA-binding protein (CIRP), RNA-binding motif protein 3 (RBM3) and serine and arginine rich splicing factor 5 (SRSF5) are RNA-binding proteins that are transcriptionally upregulated in response to moderately low temperatures and a variety of cellular stresses in mammalian cells. Induction of these cold-inducible proteins (CIPs) is dependent on transient receptor potential (TRP) V4 channel protein, but seems independent of its ion channel activity. We herein report that in addition to TRPV4, TRPV3 and TRPM8 are necessary for the induction of CIPs...

DEAD-box RNA helicases (DBRHs) modulate RNA secondary structure, allowing RNA molecules to adopt the conformations required for interaction with their target proteins. RH50 is a chloroplast-located DBRH that co-localizes and is co-expressed with GUN1, a central factor in chloroplast-to-nucleus signaling. When combined with mutations that impair plastid gene expression (prors1-1, prpl11-1, prps1-1, prps21-1, prps17-1 and prpl24-1), rh50 and gun1 mutations evoke similar patterns of epistatic effects. These observations, together with the synergistic growth phenotype of the double mutant rh50-1 gun1-102, suggest that RH50 and GUN1 are functionally related and that this function is associated with plastid gene expression, in particular ribosome functioning...

Cold-inducible RNA-binding protein (CIRP) is a cold-shock protein which can be induced after exposure to a moderate cold-shock in different species ranging from amphibians to humans. Expression of CIRP can also be regulated by hypoxia, UV radiation, glucose deprivation, heat stress and H2O2, suggesting that CIRP is a general stress-response protein. In response to stress, CIRP can migrate from the nucleus to the cytoplasm and regulate mRNA stability through its binding site on the 3'-UTR of its targeted mRNAs...

The causal agent of pine wilt disease, pine wood nematode (PWN) (Bursaphelenchus xylophilus), revealed extended lifespan at low temperature. To discover the molecular mechanism of this phenomenon, we attempted to study the molecular characterization, transcript abundance, and functions of three genes of the cyclic guanosine monophosphate (cGMP) pathway from B. xylophilus. Three cGMP pathway genes were identified from B. xylophilus. Bioinformatic software was utilized to analyze the characteristics of the three putative proteins...

OBJECTIVES: Cold-inducible ribonucleic acid-binding protein (CIRP) has been identified to play a role in the antiapoptotic effect of hypothermia. We sought to investigate the renoprotection of CIRP in a rat model of deep hypothermic circulatory arrest. METHODS: Overexpression and knockdown of CIRP were achieved in vivo by directly injecting lentivirus vectors containing packaging lentivirus (pL)/internal ribosome entry site (IRES)/green fluorescent protein (GFP)-CIRP or pL/short hairpin RNA (shRNA)/F-cold inducible RNA binding protein (F-CIRP)-A into the renal parenchyma of rats 7 days before deep hypothermic circulatory arrest under the ultrasound guidance...

Recent years have seen an upsurge of interest on brown adipose tissue (BAT) to combat the epidemic of obesity and diabetes. How its development and activation are regulated at the post-transcriptional level, however, has yet to be fully understood. RNA binding proteins (RBPs) lie in the center of post-transcriptional regulation. To systemically study the role of RBPs in BAT, we profiled >400 RBPs in different adipose depots and identified Y-box binding protein 2 (Ybx2) as a novel regulator in BAT activation...

BACKGROUND: Hemorrhagic shock (HS) is an important cause of mortality. HS is associated with an elevated incidence of acute lung injury and acute respiratory distress syndrome, significantly contributing to HS morbidity and mortality. Cold-inducible RNA-binding protein (CIRP) is released into the circulation during HS and can cause lung injury. C23 is a CIRP-derived oligopeptide that binds with high affinity to the CIRP receptor and inhibits CIRP-induced phagocyte secretion of TNF-α...

Extracellular cold-inducible RNA-binding protein (CIRP) functions as damage-associated molecular pattern (DAMP) and has been demonstrated to be responsible in part for the damage occurring after renal ischemia-reperfusion (I/R). A short peptide derived from CIRP, named C23, binds to myeloid differentiation factor 2 (MD2), a Toll-like receptor 4 (TLR4) co-receptor. We hypothesize that C23 reduces renal ischemia-reperfusion (RIR) injury by blocking CIRP. We observed that pre-treatment with C23 significantly decreased the levels of recombinant mouse CIRP-induced TNF-α in a dose-dependent fashion in cultured macrophages...

Cold shock proteins (Csps) enable organisms to acclimate to and survive in cold environments and the bacterial CspA family exerts the cold protection via its RNA chaperone activity. However, most Archaea do not contain orthologs to the bacterial csp. TRAM, a conserved domain among RNA modification proteins ubiquitously distributed in organisms, occurs as an individual protein in most archaeal phyla and has a structural similarity to Csp proteins, yet its biological functions remain unknown. Through physiological and biochemical studies on four TRAM proteins from a cold adaptive archaeon Methanolobus psychrophilus R15, this work demonstrated that TRAM is an archaeal Csp and exhibits RNA chaperone activity...

Induced by hypothermia, cold-inducible protein RBM3 (RNA-binding protein motif 3), has been implicated in neuroprotection against various toxic insults such as hypoxia and ischemia. However, whether mild hypothermia and RBM3 prevent neural cells from UV irradiation-elicited apoptosis is unclear. In the present study, human neuroblastoma cell line SH-SY5Y was used as a cell model for neural cell death, and it was demonstrated that mild hypothermia protects SH-SY5Y cells from UV irradiation-induced apoptosis...

Freezing temperatures are a major challenge for life at the poles. Decreased membrane fluidity, uninvited secondary structure formation in nucleic acids, and protein cold-denaturation all occur at cold temperatures. Organisms adapted to polar regions possess distinct mechanisms that enable them to survive in extremely cold environments. Among the cold-induced proteins, cold shock protein (Csp) family proteins are the most prominent. A gene coding for a Csp-family protein, cspB, was cloned from an arctic bacterium, Polaribacter irgensii KOPRI 22228, and overexpression of cspB greatly increased the freeze-survival rates of Escherichia coli hosts, to a greater level than any previously reported Csp...

BACKGROUND: Intestinal ischemia-reperfusion can occur in shock and mesenteric occlusive diseases, causing significant morbidity and mortality. Aside from local injury, intestinal ischemia-reperfusion can result in remote organ damage, particularly in the lungs. Cold-inducible RNA-binding protein (CIRP) was identified as a novel inflammatory mediator. We hypothesized that a deficiency in CIRP would protect the lungs during intestinal ischemia-reperfusion injury. METHODS: Intestinal ischemia was induced in adult male C57BL/6 wild-type and CIRP knock-out (CIRP(-/-)) mice via clamping of the superior mesenteric artery for 60 minutes...

Rhinoviruses (RVs) are the major causes of common colds in humans. They have a nonenveloped, icosahedral capsid surrounding a positive-strand RNA genome. Here we report that the antigen-binding (Fab) fragment of a neutralizing antibody (C5) can trigger genome release from RV-B14 to form emptied particles and neutralize virus infection. Using cryo-electron microscopy, structures of the C5 Fab in complex with the full and emptied particles have been determined at 2.3 Å and 3.0 Å resolution, respectively. Each of the 60 Fab molecules binds primarily to a region on viral protein 3 (VP3)...

The functions of many bacterial RNA-binding proteins remain obscure because of a lack of knowledge of their cellular ligands. Although well-studied cold-shock protein A (CspA) family members are induced and function at low temperature, others are highly expressed in infection-relevant conditions. Here, we have profiled transcripts bound in vivo by the CspA family members of Salmonella enterica serovar Typhimurium to link the constitutively expressed CspC and CspE proteins with virulence pathways. Phenotypic assays in vitro demonstrated a crucial role for these proteins in membrane stress, motility, and biofilm formation...

Cold-inducible RNA binding protein (CIRP) was discovered after the cells were exposed to a moderate cold shock because its production was induced. Other cellular stresses such as ultraviolet light radiation and hypoxia also could increase its expression. Under stress conditions, CIRP could up regulate its own expression by self-transcriptional activation of alternative promoters. After relocating into cytoplasm from nucleus, CIRP assists cells in adapting to novel environmental conditions via stabilizing specific mRNAs and facilitating their translation...
