Objective To investigate the clinical significance and abnormal expression of the CREB in different grade gliomas. Methods The expression of CREB was examined by using immunohistochemistry in brain tissues from the brain injury (5 cases) and different grade gliomas (55 cases).The mRNA and protein levels of CREB were further as?sessed using Western blot and RT-PCR in brain tissues from the patients with brain injury (10 cases) and those with dif?ferent grade gliomas (30 cases). Results The positive rates of CREB immunohistochemistry were 2/5 in control, 10/15 inⅠ-,Ⅱ11/12 in Ⅲ, 28/28 in Ⅳ. The positive rates of CREB were significantly different among different groups (H=28.183,P<0.05).The mRNA levels of CREB were 1.00 ± 0.000 in control, 1.35 ± 0.068 inⅠ-Ⅱ, 2.88 ± 0.111 in Ⅲand 3.75 ± 0.196 in Ⅳ. The expression of CREB was higher in the glioma than in control group, and the mRNA levels of CREB were significantly different among different groups(F=1.208,P<0.05). The protein levels of CREB were 0.311 ± 0.014 in control, 0.469±0.026 inⅠ-Ⅱ, 0.641±0.028 inⅢand 0.896±0.024 inⅣ. The protein levels of CREB were sig?nificantly different among different groups(F=1.123,P<0.05). Conclusion The expression of CREB is elevated in glio?mas with different differentiation degrees. The expression of CREB was positively correlated with the degree of differentia?tion, indicating that CREB may have an important regulatory role in the progress of gliomas.

Objective To construct a T-bet response reporter gene, for the detection of T-bet tran-scriptional activity and application in high-throughput screening for the functional genomies. Methods The cis-acting DNA element, ThRE, based on CNS-22 T box site of IFN-γ gene, was recombined into a reporter vector pLUC-MCS. The reporter gene was transfected into HEK 293T cells to detect its response to T-bet. And the binding of T-bot to TbRE was identified with electrophoretic mobility shift assay(EMSA). Results ThBE was successfully cloned into pLUC-MCS, named as TbRE-LUC. Using a luciferase assay, expression of the reporter gene is found to be induced by T-bet in a dose dependent manner and correlate with T-bet ex-pression positively with activation up to 20 folds. Moreover, the binding specificity of T-bet to TbRE is vali-dated by EMSA. Conclusion We successfully constructed a T-bet response reporter gene, ThRE-LUC, which responds to T-bet keenly and specifically. TbRE-LUC will be a useful tool in high-throughput screen-ing for human genes associated with transcription activity of T-bet.
