Effect of Genetic and Epigenetic Factors on the Clinical Response and Toxicity to Doxorubicin Among Egyptian Breast Cancer Patients

Ain Shams University200 enrolled

Overview

Recent advances in technologies, such as microarray and high-throughput sequencing, represented a deeper understanding of molecular biology, especially noncoding RNA (ncRNA). It was found that there are only \<2 % of the total genome sequence as protein-coding genes while at least 98 % of the genome are transcribed into ncRNA. In the past, non-protein-coding RNAs were known as "transcription noise," but now it is obvious that ncRNAs play a crucial regulatory role in cell differentiation and organism growth and metabolism.
