WebApr 9, 2024 · Regulation can be qualitative (i.e. gene expression is either “on” or “off”) or quantitative (i.e. expression levels can be modulated “up” or “down”). Fluctuations in the intensities of external stimuli coupled to changes that occur at the genomic level result in different developmental outcomes or physiological states. WebDec 5, 2010 · In this study we addressed the mechanisms involved in the protection of the p53 tumor suppressor gene against epigenetic silencing in human transformed cell lines. We characterized a binding site for the CCCTC-binding factor (CTCF) in the human p53 gene promoter that contributes to its transcriptional expression, and has the ability to …
