Abstract:
OBJECTIVETo construct differential expression profiles of adenoid cystic carcinoma cell lines for screening candidate genes related to metastasis and to verify some candidate genes in adenoid cystic carcinoma.
METHODSRestriction fragments differential display PCR (RFDD-PCR) was used to set up gene expression profiles of adenoid cystic carcinoma cell lines-ACC-M and ACC-2, with high and low metastasis potential respectively. Candidate genes were screened through bioinformatics analysis. Then, a gene family of these candidate genes was checked using semi-quantitative reverse transcription-PCR(RT-PCR).
RESULTSTwo gene expression profiles including 5420 gene fragments were constructed, 12 genes of a family called matrix metalloproteinase genes (MMPs) were observed obvious differentially expressed between two cell lines. Results of semi-quantitative RT-PCR also identified this different expression of MMP2,MMP7,MMP9,MMP14,MMP15 and MMP24.
CONCLUSIONThe construction of gene expression profiles of ACC-M and ACC-2 cell lines makes the foundation for seeking the target genes of adenoid cystic carcinoma. MMP2,MMP7,MMP9 and MMP15 may be relevant with carcinogenesis, development and metastasis of adenoid cystic carcinoma, and different metastasis potential may result from different subtype of MMPs gene family.
