Abstract
Abstract Cervical carcinoma is one of the most common cancers in females. This cancer begins with precancerous stages and can evolves to carcinoma over 10 years or more. Cervical cancer is a multistep process with accumulation of genetic and epigenetic alterations in regulatory genes, leading to activation of oncogenes and inactivation or loss of tumor suppressor genes. We aimed to identify genetic alterations associated with pre-cancerous stage and also with cervical cancer. For this purpose, microarray comparative genomic hybridization(Illumina 450K and Illumina Expression HT12 Human CGH Whole-Genome Arrays) was performed with 16 cases of cervical intraepithelial neoplasia(CIN) of different stages and 3 cases of carcinoma. We identified epigenetic inactivation of TSGs by hyper- or hypo-methylation which has been recognized as an important and alternative mechanism in tumorigenesis. Here we discuss these epigenetic alterations in cervical intrapeithelial neoplasia and cervical cancer focusing on DNA methylation. Citation Format: Kwon Yongil, Nakwoo Lee, Sungjong Lee.
