This is very focused and updated review on a topic that is capturing increasing interest in the scientific community. The manuscript is written in a clear and readable manner.
There is only a minor typing error to be corrected at page 4, right column: "metabolic stresses and thereof sensitized sensitizes hepatocellular".
The literature cited covers the most relevant papers, though the authors have failed to cite some review-papers on this same subject. Also, the implications in the biology and therapy of diseases (Conclusion, page 5), and in particular of cancer could be expanded. In this respect, I would recommend the authors to refer to the papers listed below. The readers would appreciate to read more about the role of miRNAs in the cross-talk between apoptosis and autophagy and the implications in cancer development and chemoresistance. I am in favor of the publication of this article provided that the authors address the above issues.
