1.Question: What is the basic problem that your research focuses on and is done to solve?Please specify the main knowledge gap that your article has filled in the text.
Answer: We have rewritten the first sentence of the abstract, describing the problem that the experiment will solve.
2.Question: The conclusion is very wide and general.It is better to add a specific conclusion from your specific results.
Answer: Thank you for your suggestion. Glucose metabolism encompasses a wide range of processes, and we only tested GLUT4, it is insufficient to fully represent cellular glucose metabolism.. Therefore, we have revised the title, conclusion and removed the content related to glucose metabolism from the manuscript (in Line 30-32).
3.Question: It is better to explain about importance and application of animal breeding, especially cattle. For this you can use added sentences and references.
Answer: Thank you for providing the references, but we believe that the relevance between the references you provided and our research content is relatively low. Our research aims to address the mechanisms underlying postpartum reproductive dysfunction in dairy cows caused by energy metabolism disorders.
4.Question: Please specify in the objective whether your research is being conducted for the first time in the world or is it a continuation of another research?Please specify the main knowledge gap that your article has filled.
Answer: Thank you for your suggestion, it has been very helpful in improving the content of our manuscript. We have added a description of the purpose of this study in Line 96-99 & Line 101-104.
5.Question: please add full name for abbreviations in the first place of text.
Answer: Thank you, we have added the full name (Line 116).
6.Question: indices or indexes??? Please check.
Answer: We have changed indices to indices in Line 176.
7.Question: this sentence isn't complete and clear?! what do you mean? tablethis sentence isn't complete and clear?!?
Answer: We apologize for the writing error and have rewritten the sentence (in Line 237-240).
8.Question: identify quality and quantity of extracted RNA?
Answer: Dear reviewer, we measured the extracted RNA concentration (Line 233-237) using a NanoDrop 2000 spectrophotometer (Thermo Fisher Scientific, USA), and all RNA OD260/280 values were between 1.8 and 2.0, indicating that our RNA quality is suitable for subsequent experiments. The concentration of purified RNA was determined by UV spectrum at 260 nm.
9.Question: did you design primers or take from other references?
if you designed, please explain in the text how? and add your used software and ....
If you took from other references, please add reference in the text.
Answer: We designed our own genes, not based on references. We have added a description of the relevant methods for gene design in the manuscript (in Line 244-246).
10.Question: it is better to identify in the text reference genes, beta actin and GAPDH! and explain that did you use both reference genes for all genes or not??
Answer: All of our genetic experiments utilized two internal references, and we have added a description of this in the manuscript (in Line 243-244).
11.Question: please add accession number and Tm for used primers in the table!!
Answer: We have added accession number and Tm (Table 1).
12.Question: did you use animal statistical model? Please add your used model and its components in the text!
Answer: We did not employ animal statistical models. We randomly selected postpartum cows and divided them into experimental and control groups based on their serum BHBA and estrus status. On this basis, one-way ANOVA was applied to compare the levels of RBP4 and Glu in the serum of two groups of cows.
13.Question: Please compare your original result with the previous results and identify what interesting and new results you have added to the previous results.
Answer: We have rewritten this sentence based on your suggestion (Line 580-583).
14.Question: The conclusion is very wide and general. It is better to add a specific conclusion from your specific results.
Answer: Thank you for your suggestion. We have removed the relevant description of Glu metabolism from the conclusion.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe manuscript submitted for review examined whether elevated retinol binding protein4 (RBP4) in cows with subclinical ketosis affects granulosa cell viability and steroid function and interferes with glucose utilization by the cells. The authors compared subclinical ketosis cows in their second to third month after parturition to comparable cows without subclinical ketosis. Through a progressive set of in vivo and in vitro cell culture studies, they determined that elevated RBP4 inhibited cell mitosis, promoted apoptosis, and interfered with glucose metabolism by inhibiting GLUT4 transport of glucose. The authors determined that RBP4 acts through its receptor STRA6 and the PI3/AKT pathway to exert its effects. The study's major caveat is that by pooling tissues, they did not consider cow variability. Overall, well-designed and executed studies leading to sound conclusions.
