Abstract
BACKGROUND Here, we explored the genetic interactions between diabetes and oncogenic single-nucleotide polymorphisms (SNPs) that determine colorectal cancer (CRC) morbidity. METHODS 8q24 rs6983267 polymorphism analysis and cDNA microarray were performed in 107 CRCs to identify the genes associated with diabetes and the oncogenic SNP. Then clinical significance of the gene was validated in 132 CRCs. Meta-analysis of microarray data and diabetic comorbidity was performed. RESULTS Of genes associated with a minor SNP allele at 8q24, diabetes, and MYC overexpression, apolipoprotein A-IV (ApoA-IV) was associated with oncogenesis and poor prognosis in CRC patients. Patients with high ApoA-IV expression showed significantly poorer prognosis by univariate and multivariate analysis. Meta-analysis revealed lipid metabolism was associated with ApoA-IV-related oncogenesis in diabetic patients. CONCLUSIONS Changes in lipid metabolism associated with aberrant expression of ApoA-IV were risks for CRC oncogenesis.

Abstract
BACKGROUND The rs6983267 at 8q24.21 has been established as a significant cancer-related single nucleotide polymorphism (SNP). The risk allele showed similarity to the binding site of transcription factor TCF4/LEF1 that activates transcription of MYC. However, little is known about the role of this SNP in increasing MYC activity in colorectal cancers (CRCs). METHODS The genotypes of rs6983267 in peripheral blood and primary cancers, MYC activity and copy number (CN) alteration were examined in 107 CRCs. Next, we plotted the number of cancers cell lines exhibiting specific G/T genotypes in 746 cancer cell lines of the Sanger Institute database. Then we validated the relationship between the 8q24 SNP status and clinicopathologic parameters in 68 CRCs with loss of heterozygosity (LOH). RESULTS The MYC module activity was activated by either transcription in the risk allele (G) or by amplification in the non-risk allele (T). Then, we confirmed that the CN amplification dominantly occurred in the non-risk allele, whereas CN neutral LOH, which indicated uniparental disomy (UPD) was more frequently observed for the risk allele. Finally, we confirmed that risk allele dominant cases, either by amplification or by UPD, indicated a more malignant clinical phenotype than non-risk allele dominant cases. CONCLUSIONS The development of CRC requires MYC activation through retention of the risk allele, or amplification of the non-risk allele at the oncogenic SNP in the site of primary tumor.
