The Role of HDACs in the Response of Cancer Cells to Cellular Stress and the Potential for Therapeutic Intervention
Round 1
Reviewer 1 Report
This review covers a great deal of territory regarding an important cluster of bioactive agents.
In general the text flows well and is clear but there is certainly room for improvement as the following comments reveal.
1. The wording of the bottom line of the Abstract is indistinct. Similarly at the bottom of Figure 1.
2. There are inappropriate choice of words on occasions such as "wretched' (line 69), "outrageous" (157), inconsistent (158, 167), sighted (169), add 'up" to give "to sum up" (436), "the" to be inserted before tumor (484), "of" to be removed (501, 709), spelling of mitochondria is spelled incorrectly (Figure 5), above mentioned (581), "grant" should be replaced by "allow" (651) and lines 691 / line 692 needs rephrasing.
Apart from these considerations, this review is recommended for publication.

Reviewer 2 Report
The manuscript is well structured and contains a good overview of the field of HDAC inhibitors and their molecular mechanisms especially regarding cellular stress. In some places the authors could add more recent references and important results. Especially in paragraph 4 where immunotherapies are described. Here an entry on the interaction of the PDL1 system with different HDAC subtypes would be appropriate.
