Abstract
Background
Shisa3 is a novel tumor suppressor identified in lung cancer. However, its antitumor activity in other human cancers and the mechanism of gene inactivation remain unknown.
Methods
SHISA3 expression was measured by reverse transcription-PCR (RT-PCR) and quantitative RT-PCR (RT-qPCR). DNA methylation was determined by bisulfite sequencing and pyrosequencing.
Results
Down-regulation of SHISA3 expression was observed in all of 11 colorectal cancer (CRC) cell lines and was further confirmed in 34 (65.4 %) of 52 colorectal carcinomas by RT-qPCR. Four of six CRC cell lines could restore SHISA3 expression after treatment with 5-aza-2′-deoxycytidine. Tumor-specific methylation of five CpG sites in the first intron of SHISA3 was identified by bisulfite sequencing, and their methylation levels were quantified in 127 pairs of primary CRC tissues by bisulfite pyrosequencing. The methylation levels of SHISA3 in tumors were noticeably higher than that in their matched normal mucosae. In addition, SHISA3 hypermethylation was significantly associated with an increased risk of disease recurrence in patients with stage II and III disease (P = 0.007) and was an independent predictor of poor overall survival [hazard ratio (HR) 2.9, 95 % confidence interval (CI) 1.5–5.8; P = 0.002] and disease-free survival (HR 4.0, 95 % CI 1.6–10.2; P = 0.003) of CRC patients.
Conclusions
SHISA3 gene is epigenetically inactivated in a substantial fraction of CRC, and its hypermethylation is of prognostic significance in predicting clinical outcome. The quantitative bisulfite pyrosequencing assay established could be a cost-effective tool for providing a potential biomarker of adverse prognosis in CRC.
