Abstract:
Objective To investigate the expression profile of cancer-related genes in human bone marrow-derived neural stem cells (Md-NSCs) to determine whether there are any characteristics that could help the evaluation of their tumorigenic potentials.Methods Md-NSCs were cultured in vitro and identified (experimental group);fresh human adult bone marrow cells were used as control group (sifting erythrocytes).The expression profiles of 440 cancer-related genes in cells from the two groups were analyzed by Oligo GEArray Human Cancer Microarray OHS-802;real-time quantitative PCR was performed to detect the expressions of oncogene MYC,matrix metalloproteinase 2 (MMP2),Notch congener 2 (Notch2),stanniocalcin 1 (STC1),integrin α3 (ITGA 3),signal transduction and transcriptional activation factor 5b (STA T5b),Ras congene gene family C (RhoC),and wingless-type MMTV integration site family member 1 (Wnt1).Results As compared with those in the control group,the Md-NSCs from experimental group had 66 tumor-related genes with high expressions (＞3 folds).MYC,MMP2,Notch2,STCI,ITGA3,STA T5b,RhoC and Wnt1 expressions in the Md-NSCs from experimental group were significantly higher than those in the control group (P＜0.05),whose results were accorded with genechip detection results,enjoying the folds of 4.35×100,2.84×100,2.87×100,3.41 ×102,2.22×102,6.99× 100,4.92 × 100 and 3.64 ×100,respectively.Conclusion A number of cancer-related genes are over-expressed in Md-NSCs,and the activations of some of these important oncogenes have been proved to promote human tumorigenesis.
