Study of Epigenomic Changes (Noncoding -Tag. Oncogene) In Primary Cells of Cancer Patients than Biopsy Cells from Normal Tissue

Abstract

Saeed Soroush

The epigenetic is a set of controlled reversible processes which causes inherited changes in the expression of genes Independent of the change in the nucleotide sequence of DNA. Changes in heterochromatin to yochromatin and vice versa. In DNA Methylation, Histone Modifications are considered as epigenetic mechanisms which regulates target genes in the transcription machine and On the other hand, the interaction of non-coding RNAs like Micro RNAs With target gene has identified their roles in the growth of differentiation and cell death. Therefore, epigenetic factors directly or indirectly change the expression of Micro RNAs in the cell. Certainly failure in these mechanisms leads to activating or inhibiting different messaging pathways and causing diseases such as cancer. As you know, the differentiation and survival of cells occur due to constant gene control patterns that also cancer is created as a result of a change in expression of the activity of carcinogenic genes or tumor suppressor genes. The expression of genes at the DNA and chromatin levels is regulated through epigenetic mechanisms. Of these, some small molecules and drugs that interact with specific sequences of DNA can be modified locally and allow the transcriptional machine to reach the target genes and, ultimately, to change the heterochromatin to the cochromatin, can be mentioned.
