Cyclins and histones
WebJun 1, 2003 · Histone deacetylase (HDAC) inhibitors are known to induce expression of genes such as p21(WAF1), thereby, leading to cell cycle arrest. In this work, we show that p21(WAF1) induction by HDAC inhibitors (depsipeptide and trichostatin A) is defective in Ataxia telangiectasia (AT) cells but normal in matched wild-type (WT) cells (human … WebStudy with Quizlet and memorize flashcards containing terms like In vertebrates, differentiation of cells is influenced by Select one: a. variations in the organism's DNA. b. where the cells migrate. c. whether the cell is apical or basal. d. how rapid the first divisions are., In a single-celled organism, mitosis is used for Select one: a. development. b. epair. …
