N2 - Activity of nonsense-mediated mRNA degradation (NMD) was studied in several mammalian cell cultures using recently developed genetically encoded fluorescence sensor [Pereverzev et al., Sci. Rep., 2015, vol. 5, p. 7729]. This NMD reporter enables measurement of NMD activity in single live cells using ratio of green and red fluorescent proteins signals. The following cell lines were analyzed: mouse colon carcinoma CT26, mouse Lewis lung carcinoma LLC, human T-cell leukemia Jurkat, and spontaneously immortalized human keratinocytes HaCaT. These cell lines demonstrated very different NMD activities. In CT26, NMD activity was low, whereas in LLC it was high (8.5-fold higher than in CT26). Jurkat and HaCaT cells possessed strong heterogeneity and consisted of two cell subpopulations with high and low NMD activities. In addition, we detected high NMD activity in primary culture of mouse embryonic hippocampal neurons.
