Objective To explore the influence of mild hypothermia therapy on expression of heat shock protein(HSP)60,HSP70,HSP90 in lymphocyte in patients with severe craniacerebral injury.Methods 23 patients with severe craniacerebral injury were randomly divided into the mild hypothermia group (12 cases) and the normothermia group(11 cases).At the base of routine therapy,the mild hypothermia group received mild hypothermia therapy by the temperature control blanket to keep the body temperature among 32～34℃ for 4～6 d.The expression of HSP60,HSP70,HSP90 in lymphocyte were measured by Western Blot at the 1st d,4th d and 8th d after treatment.The infection incidence was observed at 7 d after treatment.And the expression of HSPs in lymphocyte at 32℃ and 37℃ in normal control group were measured respectively.Results Compared with normothermia group,the expression of HSP60 in mild hypothermia group was significantly lower at each time point(all P

Objective To clarify the relationship between CT120,a novel human plasma membrane-associated gene,and the proliferation of lung adenocarcinoma cell line A549.Methods Expression vector(pcDNA3.1)containing antisense oligonucleotides of CT120 was constructed and transfected into the adenocarcinoma cell line A549.RT-PCR and Western blot detected the expression of CT120.Meantime,flow cytometry and soft agarose colony formation were applied for cell proliferation,and P53,CyclinD1 and CDK4 were detected by RT-PCR.ResultspcDNA3.1 containing antisense oligonucleotides of CT120 was successfully constructed and inhibited the expression of CT120 effectively by RT-PCR and Western blot.The expression of P53 was up-regulated and the expression of CyclinD1 and CDK4 were down-regulated.Conclusion The down-regulation of CT120 expression by antisense oligonucleotides technique may be a potential drug target for treatment of lung cancer.
