原始摘要

Uterine cervical carcinoma (CACX) is one of the leading causes of deaths in Indian women. Chromosomal alterations including 11p15.5 locus were reported in CACX. Consequently, we strived for the first time to understand the molecular status of the candidate gene Insulin-like growth factor 2, IGF2 (11p15.5) in Indian CACX patients (n = 128). DNA copy number (CN) analysis using CGH-SNP analysis showed no genetic alteration and it was further validated by comparison with publicly available CN datasets. But promoter hypo-methylation during the progression of CACX was observed and also found to be concordant with publicly available DNA methylation datasets. Interestingly, we found diverse expression of IGF2 transcript in both normal cervical epithelium (NCE) and CACX tumors. Similar heterogeneous expression pattern was seen in publicly available expression datasets as well. Finally, protein expression analysis in NCE showed concordance with transcript expression but tumors showed frequent low expression. Log-rank test showed a difference (p-value = 0.057) in overall survival between cases with and without alteration for IGF2 in Indian CACX patients. Collectively, our study proposes that regulation of IGF2 expression in NCE appeared to be multifaceted and deregulation during the development of CACX resulted in the differential expression.
