Objective To construct a cDNA subtractive library of genes transactivated by c-terminally truncated middle surface protein of hepatitis B virus(MHBs t) with suppression subtractive hybridization technique for cloning genes associated with transactivation. Methods The mRNA was isolated from HepG2 cells transfected with pcDNA3.1(-)-Mt167 and pcDNA3.1(-) empty vectors, respectively, then cDNA was synthesized. After restriction enzyme Rsa I digestion, small-size cDNAs were obtained. Then tester cDNA was divided into two groups and ligated to the specific adaptor 1 and adaptor 2, respectively. After tester cDNA was hybridized with driver cDNA twice and underwent two times of nested PCR and then was subcloned into T/A plasmid vectors to set up the subtractive library. Amplification of the library was carried out with E. coli strain JM109. The cDNA was sequenced and analyzed in GenBank with Blast search after PCR. Results The subtractive library of genes transactivated by MHBs t was constructed successfully. The amplified library contained 94 positive clones. Colony PCR showed that these clones contained 200-800bp inserts. Sequence analysis was performed in 50 clones,and the full length sequences were obtained with bioinformatics method. 23 coding sequences were obtained in total, which consisted of 19 known and 4 unknown ones.Conclusions The obtained sequences may be target genes transactivated by MHBs t, among which some genes coding proteins may involve in cell cycle regulation, immune response and tumour genesis.

BACKGROUND: Cardiac stem cells can differentiate into cardiomyocytes in vitro under induction of pilose antlerpolypeptides, which provides a new therapeutic idea for myocardial injury.OBJECTIVE: To explore the effect of pilose antler polypeptides on the apoptosis rate and membrane stability ofmitochondria in cardiac stem cells.METHODS: We chose healthy male Wistar rats born 2 days to extract cardiac stem cells. The culture dish was used asthe experimental unit, and extracted cells were divided into the following four groups (n=12). Blank control group: Thesame amount of buffer was added for induction; 5-azacytidine group: induced with 5-azacytidine (3 μmol/L); pilose antlerpolypeptides group: induced with pilose antler polypeptides (800 mg/L); combined group: induced with pilose antlerpolypeptides (800 mg/L) and 5-azacytidine (3 μmol/L). After 48 hours induction, apoptosis rate of cardiac stem cells ineach group was detected with flow cytometry. The membrane potential of mitochondria in cardiac stem cells wasdetected with immunofluorescence. The expression level of Nkx 2.5, GATA4, ATF-2, and MEF-2C in cardiac stem cellswas detected using western blot assay.RESULTS AND CONCLUSION: There were small, round and bright cells after 2 weeks culture, and cell colonies ofcardiac stem cells formed. The apoptosis rate of cardiac stem cells in the 5-azacytidine group increased significantly (P <0.05) and its membrane potential decreased significantly compared with the blank control group (P < 0.05). Theapoptosis rate of cardiac stem cells in the pilose antler polypeptides group and combined group decreased significantlycompared with the 5-azacytidine group (P < 0.05, P < 0.01), and their membrane potential increased significantly (P <0.05, P < 0.01). The results of western blot showed that the expression level of Nkx2.5 increased significantly in thepilose antler polypeptides group and combined group compared with the 5-azacytidine group (P < 0.05), while theexpression levels of GATA4 and ATF-2 in each group were low and there were no significant differences among groups(P > 0.05). The expression level of MEF-2C in each group was at a middle level, and there were no significantdifferences among groups (P > 0.05). To conclude, our experimental findings indicate that pilose antler polypeptidescould decrease the apoptosis rate and improve membrane stability of mitochondria in cardiac stem cells. Themechanism may be related to the increased expression of Nkx 2.5, but whether the mechanism is related to GATA4,ATF-2 and MEF-2C needs to be further studied.

Objective To screen stage\|specific expression genes of plerocercoid of Spirometra erinacei\|europaei. Methods RNA was extracted by the acid guanidinium thiocyanate\|phenol\|chloroform from plerocercoid and adult worm of Spirometra erinacei\|europaei. Contaminated DNA in the RNA was digested by RNase\|free DNase. cDNA was synthesized by using T\-\{12\}MA, T\-\{12\}MC, T\-\{12\}MG and T\-\{12\}MT primers, and PCR was then done using the same T\-\{12\}MN and one random primers. The PCR products were fractionated on 8% denatured polyacrylamide gel, differential bands of plerocercoid found in the gel were cut out, amplified by PCR and sequenced after the gel was dried out and autoradiographed. Northern hybridization was conducted to identify the stage\|specific expression genes. Results Eleven differential bands were selected from the gel and classified into 3 kinds of gene fragments by hybridization after they were amplified by PCR. The fragments 1 and 2 were confirmed to express specifically in plerocercoid by Northern hybridization, but the fragment 3 was expressed in both plerocercoid and adult worm. When the 3 gene fragments were homologically analyzed in GenBank, the sequence which was homologous with the fragments 1 and 2 was not found, but the fragment 3 had high homology with many kinds of 28S rRNA. Conclusion The gene expression of plerocercoid was different from that of adult worm probably because they live in different hosts. Two kinds of different gene fragments in plerocercoid were identified by mRNA differential display technique.
