**********

In the revised version of the manuscript "NF-Y Dependent Epigenetic Events Discriminate Between Mitotic and Postmitotic Status" Gurtner and coworkers have addressed suggestions and criticisms to an almost satisfactory extend. However a number of issues are still pending and some new arose:
Fig.1 NF-YA immunostaining is different between panels A and B, in the former NF-YA is present in the nucleolus whereas in the latter is not despite the same protocol was used. Same in Fig.4.
Fig.2 Panel B could benefit from the substitution of numbers with the names of the promoters.
Fig.4 (Old Fig.5) panel D still supports the recruitment of HP1α to Cyclin B2 promoter. Authors should comment.
The manuscript still contains a huge number of typos, grammar and syntax errors. Even if I do not strongly support the manuscript publication; it is however acceptable, in the spirit of the journal, for publication on Plos One after a careful language editing.
