Proof for the generalizability in the bifurcation in CDK2 activity, Rb phosphorylation, and p21 expression. (A) Single-cell traces of CDK2 activity for CDK2inc cells (blue) and CDK2low cells (red). For clarity, 250 manually verified traces are plotted for every single cell line of thousands analyzed; the numbers of CDK2inc and CDK2low traces plotted right here are BRD9185 web proportional towards the fractions of each and every at the population level. CDK2low : MCF10A, 26 ; RPE-hTERT, 31 ; HLF, 23 ; MCF7, 18 ; U2OS, 17 ; and HCT116, 1 . (B) Single-cell measurement of phospho-Rb (S807/811) as a function of time-since-anaphase for all cells analyzed. Cells were imaged for 24 h, fixed, and stained for phospho-Rb, along with the immunofluorescence image was registered to the final frame from the film. MCF10A, n = 15,446 cells; RPE-hTERT, n = 11,936 cells; HLF, n = 547 cells; MCF7, n = 7,659 cells; U2OS, n = 5,348 cells; and HCT116, n = eight,157 cells. (C) Single-cell measurement of p21 as a function of time-since-anaphase as in B. MCF10A, n = 19,052 cells; RPE-hTERT, n = 2,809 cells; HLF, n = 1,019 cells; MCF7, n = 1,929 cells; U2OS, n = 4,958 cells; and HCT116, n = 825 cells.Moser et al. PNAS | vol. 115 | no. 35 | ECELL BIOLOGYCDK2low , whereas MCF7 and U2OS cells have been intermediate with 18 and 17 CDK2low , respectively. HLF cells had been comparable with these, with 23 of cells getting into the CDK2low state, whereas RPE-hTERT cells had been the least probably to promptly enter an additional cell cycle, with 31 getting into the CDK2low state after mitosis under optimal growth circumstances. We next examined the phosphorylation state of Rb in these six cell sorts. Not only is Rb a canonical CDK2 substrate, but the phosphorylation status of this protein is deemed an indicator of a cell’s position relative towards the Restriction Point (18, 24, 25). Right after 24 h of time-lapse imaging, we fixed and stained cells for phospho-Rb at Serine 807/811. Phospho-Rb is bimodally distributed (SI Appendix, Fig. S1), and we take into consideration the high mode to represent hyperphosphorylated Rb as was accomplished previously (14, 23, 26). Through image registration, we linked th.
