||(for human cells, reference:) "To study the rates of mRNA degradation (“decay”) in human
cells, researchers measured changes in mRNA levels following application
of the RNA polymerase inhibitor Actinomycin D with Affymetrix
U95Av2 high-density oligonucleotide arrays."
||"[Investigators] thus believe that [their] 10-h median half-life figure is accurate to within 10%. Comparing this median half-life with the median half-lives of transcripts in yeast and bacteria, it appears that the half-life of the mRNA pool of a cell scales roughly in proportion to the length of the cell cycle: cell cycle lengths of 20, 90, and 3000 min correspond to median half-lives of 5, 21, and 600 min, respectively, for E. coli, S. cerevisiae, and human HepG2/Bud8 cells (primary sources)."
