The Complex Relationship between Hypoxia Signaling, Mitochondrial Dysfunction and Inflammation in Calcific Aortic Valve Disease: Insights from the Molecular Mechanisms to Therapeutic Approaches

Round 1

Reviewer 1 Report

I have read with great attention and interest the review paper entitled "The Complex Relationship between Hypoxia Signaling, Mitochondrial Dysfunction and Inflammation in Calcific Aortic Valve Disease: Insights from the Molecular Mechanisms to Therapeutic Approaches"

The authors have carried out an elegant, accurate and very well organized narrative review.

I have only one minor suggestion for the Authors: the paper is very long and verbose, it should be shortened, especially introduction and discussion.

The abstract, on the other hand, is overall unclear: I would suggest the Authors to rewrite it, briefly explain the reason for this review paper, its findings, and possible future developments

Reviewer 2 Report

With  great  pleasure I would  address several comments  about the  paper The Complex Relationship between Hypoxia Signaling, Mitochondrial Dysfunction and Inflammation in Calcific Aortic Valve Disease: Insights from the Molecular Mechanisms to Therapeutic Approaches.

The  main question of  the  paper is the  impact of tissue  hypoxia on degenerative  aortic  stenosis formation. The  topic is original and  relevant. The  paper is  the most essential and  updated review on the  topic  to the   date.

Conclusions are consistent with the  review body. Notably, authors  include  the  Table  1  with  current  data  on available treatment approaches.   References are  updated , but  have  to be  formatted in the  text  body (numbers).   Central illustration is good.  References in the  Table 1 have  to be  corrected   I highly recommend this  paper for  publication.

 

English is acceptable.

Reviewer 3 Report

The present review aims to cover the most recent understanding of the impact of the complex interplay effect of hypoxia signaling pathways, mitochondrial dysfunction, and inflammation on a key condition of cardiovascular disease, which is "calcific aortic valve stenosis”.

1.     The article is novel and interesting and addresses an hot topic in the current literature.

2.     The Introduction is well written and with good references.

3.     Although this is a general review a short paragraph at the end of introduction can be placed in order to give some information on methodology used to search articles (i.e., inclusion and exclusion criteria, time frame, databases used, type of articles included, etc).

4.     All the sections of the article are well written, but the last (5. Conclusion and Future Perspective) that is too short in the current format and needs to be expanded with more critical insight.

5.     English should be improved for style.
