RESUMO

Objective To Analyze the expression profiles of LncRNAs and mRNAs in ovarian epithelial cancer cell lines by gene mi-croarray, and then provide experimental evidences for investigating the function of LncRNAs associated with ovarian cancer. Methods The differentially expressed LncRNAs and mRNAs in ovarian epithelial cancer cell lines, such as A2780, HO8910 and SKOV3, and ovarian epithelial cell line HOSEpiC were analyzed by gene microarray. The differentially expressed mRNAs were further performed the KEGG pathway enrichment analysis. The expression levels of six candidate LncRNAs, which had significant difference between the o-varian epithelial cancer cell line and the ovarian epithelial cell line, were further verified by qRT-PCR. Results There were 227 up-regulated LncRNAs and 483 down-regulated LncRNAs in A2780, HO8910 and SKOV3 cell lines. The differentially expressed mRNAs in A2780, HO8910 and SKOV3 cell lines were mainly enriched in the tumor-related pathways such as PI3K-AKT, mTOR and TNF-α( P<0.05) . The expression levels of PTPRG-AS1, CCNT2-AS1, XLOC 009869 and LINC01138 in ovarian epithelial cancer A2780, SKOV3 and OVCR3 cell lines were up-regulated (P<0.05), while those of RP11-252P19.2 and RP11-744I24.2 in ovarian epithelial cancer A2780, SKOV3, OVCR3 and 3AO cell lines were down-regulated ( P<0.05) . Conclusion The differentially expressed LncR-NAs and mRNAs in ovarian epithelial cancer cell lines may be obtained by gene microarray, and the differentially expressed mRNAs are associated with the tumor-related pathways such as PI3K-AKT, mTOR and TNF-α, which may provide new targets for the diagnosis and treatment of ovarian cancer.

RESUMO

Objective To detect the levels of Th17 and regulatory T(Tr)cells in Imripheral blood mononuclear and tumor tissue from patients with cervical cancer and analyze the relationship hetween Th17 and Tr cells in cervical cancer progression.In addition.the significance of the Th17/Tr cells ratio in cervical cancer pathogenesis was discussed.Methods The expression levels of Th17 and Tr cells were determined by flow cytometry from 32 patients with cervical cancer and 15 health people.The mechanism of involvement of Th17 and Tr cells proportionality in cervical cancer pathogenesis and the correlation between Th17 and Trwas assessed by bivariate correlation analysis.Results The expression levels of both Th17 and Tr in patients were higher than control groups,especially in late stage patients Th17 and Tr proportionality lower than early group,and there was a negative correlation between them.Conclusion Th17 and Tr cells proportionality may be involve in the development of cervical cancer so as to provide novel strategies for tumor immunotherapy.
