The upregulation of heat shock protein 70 ( hsp70 ) gene under high temperature stress is a common phenomenon. Although protein-mediated responses play an important role in intertidal Neopyropia yezoensis , the detailed regulatory mechanism expression still unclear. Here, full-length sequence hsp70-2 was cloned and its’ regulation analyzed. There activating transcription factors element (ATFE) ...

the present study was aimed to construct a fusion plasmid harboring the extracellular domain of the influenza a m2-protein (m2e), which was fused to the n-terminus of the truncated hsp70 (hsp70359–610) molecule as a new approach for future vaccine research against influenza a. the amplified fragments, m2e and hsp70359-610 genes, were gel-purified. the products were then single digested with bam...

We have cloned a human gene encoding the 70,000-dalton heat shock protein (HSP70) from a human genomic library, using the Drosophila HSP70 gene as a heterologous hybridization probe. The human recombinant clone hybridized to a 2.6-kilobase polyadenylated mRNA from HeLa cells exposed to 43 degrees C for 2 h. The 2.6-kilobase mRNA was shown to direct the translation in vitro of a 70,000-dalton pr...

Heat shock protein 70 (HSP70) has been reported to be involved in the myocardial self-preservation system. To obtain the evidence that HSP70 plays a direct role in the protection from myocardial ischemia-reperfusion injury, rat hearts were transfected with human HSP70 gene by intracoronary infusion of hemagglutinating virus of Japan (HVJ)-liposome containing human HSP70 gene. The control hearts...

background permanent antigenic variation of influenza viruses causes a major concern to develop an effective human influenza vaccine. conserved antigens are new vaccine candidates because it is not necessary to match the prepared vaccine with circulating strains. ion channel m2 protein is conserved among all influenza a viruses, allowing the virus to enter host cells. objectives to prepare an e...

In this study we have examined the expression of a heat-shock protein (HSP) 70 gene in normal human peripheral blood leukocytes. Northern blot analysis showed that appreciable levels of hsp70 mRNA are present in monocytes and granulocytes, whereas transcript levels were barely detectable or absent in lymphocytes. Monocytes functionally activated by bacterial lipopolysaccharide (LPS) showed an e...

To determine how the modern copy number (5) of hsp70 genes in Drosophila melanogaster evolved, we localized the duplication events that created the genes in the phylogeny of the melanogaster group, examined D. melanogaster genomic sequence to investigate the mechanisms of duplication, and analyzed the hsp70 gene sequences of Drosophila orena and Drosophila mauritiana. The initial two-to-four hs...

Skin hyperpigmentation disorders due to abnormal melanin production induced by ultraviolet (UV) irradiation are both a clinical and cosmetic problem. UV irradiation stimulates melanin production in melanocytes by increasing intracellular cAMP. Expression of heat shock proteins (HSPs), especially HSP70, is induced by various stressors, including UV irradiation, to provide cellular resistance to ...
