OBJECTIVETo investigate the inhibition effect of curcumin on the proliferation of the human esophageal carcinoma cell line Ec109 and its impact on PEN/PI3K/Akt signaling pathway.
METHODSEsophageal carcinoma Ec109 cells were cultured in vitro conventionally and were treated with curcumin at different concentrations. The cell proliferation level was examined by MIT colorimetry, the ultrastructure of curcumin-treated Ec109 cells were detected with transmission electron microscope (TEM) and cell apoptosis was observed by FCM with AnnexinV-FITC/PI double staining. The protein levels of PTEN, Akt, GSK3P and Caspase 3 of curcumin-treated Ec109 cells were detected by Western blot.
RESULTSMTT test showed that curcumin could inhibit the proliferation of Ec109 cells in a time and concentration-dependent manner. TEM examination indicated that curcumin could induce Ec109 cell apoptosis. FCM detection showed that Ec109 cell apoptotic rate increased significantly with the increase of drug concentration. On the other hand, curcumin could promote the expression of PTEN, GSK3beta and Caspase 3 yet reduce the expression of Akt.
CONCLUSIONCurcumin could obviously up-regulate the expression of PTEN, GSK3beta and Caspase 3, surpress PI3K/Akt signaling pathway and hence inhibit the proliferation of Ec109 cells.

OBJECTIVETo investigate the molecular subtypes of 73 strains of Yersinia enterocolitica biotype 1A isolated in Shandong province by PFGE, and thereby to analyze the relationship between PFGE typing and biological characteristics.
METHODSSeventy-three strains of Yersinia enterocolitica biotype 1A were isolated from animal feces and meat products in Gaomi city and Wulian county in Shandong province from 2008 to 2009. Motility test, serum agglutination and virulent genes detection by PCR were used to learn the biological characteristics of the isolated strains. The molecular subtypes were determined by PFGE, whose relationships with motility, serotypes and virulent genotypes were also analyzed.
RESULTSOut of the 73 strains of Yersinia enterocolitica, 5 showed medium-active motility while the other 68 showed well-active motility. The dominated serotypes were O:5(17/73) and O:8(14/73), followed by O:9(5/73) and O:7, 8(1/73), and there was no O:3 serotype found. Meanwhile, 36 strains couldn't be serotyped. All the strains were negative with the gene ail, ystA, yadA and virF, yet the positive rate of ystB gene was 72.6% (53/73). The 73 strains of Yersinia enterocolitica isolated could be subtyped into 54 PFGE patterns (K6GN11SD0001-K6GN11SD0054), most of which only had 1 or 2 isolated strains, and no pattern was dominant. The strains in the same or similar cluster were from different hosts; each serotype and toxic genotype scattered in the clustering trees, without specific correlation with PFGE subtypes. 4 out of 5 strains, which showed medium-active motility, belonged to one branch, with the similarity coefficient at 80.9% - 100.0%; while all the toxic genotype belonged to type B.
CONCLUSIONBiotype 1A Yersinia enterocolitica has many clones, whose PFGE types had relations with motility, but no relations with virulent genotype and host.
