Transcription and regulation of rDNA in cell development

doi:10.16098/j.issn.0529-1356.2018.05.023

Abstract

Abstract:

The growth and development of cells are regulated by ribosome DNA(rDNA) and protein gene. Eighty-five percent of the total RNA is the transcription product of rDNA. Changes in rDNA transcription may lead to ribosomal biosynthesis stress, which affects cells growth, proliferation and differentiation, and further leads to the occurrence of diseases. Revealing the mechanism of rDNA transcriptional regulation is helpful to further elucidate the mechanism of cell development and find a new target for the treatment of diseases. In this paper, we describe the structure of rDNA and its transcriptional regulation,and discuss the roles of rDNA on the stem cells and occurring, treatment of disease, which provides a theoretical basis for rDNA in clinical research.

Key words: rDNA, Cell development, Regulation
