Method Abstract: "Current physiologically based pharmacokinetic (PBPK) models consider enzyme and enterocyte recovery as a lumped first-order rate. An assessment of enterocyte turnover would enable enzyme and enterocyte renewal to be modeled more mechanistically. A literature review together with statistical analysis was employed to establish enterocyte turnover in human and preclinical species." See "Method" column in table
Comments P.2019 left column 2nd paragraph: "The literature search for human enterocyte turnover data identified 17 studies, with a total sample size of 265 individuals (Supplemental Table 3), reporting the turnover of human GI [gastrointestinal] epithelial cells in the form of mean and S.D. (n = 86), mean only (n = 153), and ranges (n = 26). The majority of turnover values were from colonic, rectal (n = 157), duodenal (n = 60), and gastric epithelial cells (n = 36), whereas jejunum and ileum were limited to sample sizes of 3 and 9, respectively."
