Round 1
Reviewer 1 Report
Authors should consider the following comments to improve their manuscript:
1. References should be updated; all references cited in the manuscript are from 1985 to 2007.

Materials and Methods section need to be improved, showing more details about the experimental design.
We appreciate your review of our manuscript and valuable feedback regarding the Materials and Methods section. Based on your comments, we have revised this section to include more details about the experimental design.
We recognize the importance of providing a clear and comprehensive explanation of the methodology used in our research. We believe that these revisions have significantly improved the clarity and transparency of our Materials and Methods section. We hope these changes will help readers better understand the methodology used in our research and replicate our study if desired. Thank you for your guidance and feedback throughout this process. We appreciate your insights and suggestions, which have helped us improve our manuscript's quality.
Figures 1, 5 and 7 are too crowded.
We agree that the figures were too crowded and difficult to read. To address this issue, we have adjusted Figures 1, 5, and 7 to make them less cluttered and easier to understand. We have removed unnecessary elements and simplified the figures to highlight the most important information. We have also increased the font size and line thickness to improve readability.
We believe these changes have significantly improved the clarity and effectiveness of the figures. We hope that the revised figures will better convey our findings and help support our study's conclusions.
Results section must be improved; it is too hard to follow. Authors mentioned the use of an antibody to control tumor growth but the amount used in their experiments still unknown.
We agree that the Results section needed improvement, specifically in terms of clarity and ease of understanding. To address this, we have revised the section to make it more concise and easier to follow. We have reorganized the presentation of our results to highlight the main findings and their significance better.
Regarding the antibody used to control tumor growth, we apologize for not including the amount used in our experiments. We have updated our Results section to include this information, providing readers with a clearer understanding of our methodology.
We believe these changes have significantly improved the quality and readability of our manuscript. We hope that our revisions have addressed your concerns and that you find our manuscript's updated version satisfactory.
If two cancer cell lines are considered LMP1 active, then why to include other analysis that are unrelated to this study.
We included the other analyses better to understand the LMP1 activity in cancer cell lines. However, we understand your concern that these analyses may not be directly related to the main focus of our study. To address this, we have revised the manuscript to clarify that these additional analyses are not the primary focus of our research, and their inclusion is intended to provide additional context and support for our findings.
We have also revised the manuscript to highlight the main focus of our study, which is the characterization of LMP1 activity in two cancer cell lines. We have clarified that the additional analyses are included as supporting information, and we have provided more detailed explanations for why we chose to include them in our study.
We believe these changes have significantly improved the clarity and relevance of our manuscript. We hope that our revisions have addressed your concerns and that you find our manuscript's updated version satisfactory.
Thank you for your guidance and feedback throughout this process. We appreciate your insights and suggestions, which have helped us improve our research quality.

PMID: 24662828; PMCID: PMC4162459).
Regarding the work of Aga et al. (2014), we acknowledge the important contribution this study makes to our understanding of the invasive potential of LMP1-positive exosomes in nasopharyngeal carcinoma. Our study focused on the effects of LMP1 expression on tumor growth and metastasis in vitro and in vivo. Aga et al. (2014) investigated the role of exosomal HIF1α in supporting the invasive potential of LMP1-positive exosomes. However, our findings may have implications for the mechanism of exosome-mediated metastasis in nasopharyngeal carcinoma. Further investigation into the relationship between LMP1 expression and exosome-mediated invasion would be valuable.
- The authors should discuss the work of Verweij et al, regarding the fact that the LMP1 association with CD63 in endosomes and secretion via exosomes limits constitutive NF-κB activation (Verweij FJ, van Eijndhoven MA, Hopmans ES, Vendrig T, Wurdinger T, Cahir-McFarland E, Kieff E, Geerts D, van der Kant R, Neefjes J, Middeldorp JM, Pegtel DM.

PMID: 21527913; PMCID: PMC3117644).
Regarding the work of Verweij et al. (2011), we acknowledge that their study provides important insights into the molecular mechanism of LMP1 association with CD63 in endosomes and its secretion via exosomes, which leads to the limiting of constitutive NF-κB activation. Our study focused on the effects of LMP1 expression on tumor growth and metastasis and did not investigate the underlying molecular mechanism in detail. However, our findings may contribute to understanding the role of LMP1 in regulating the immune response and inflammation, which are closely related to NF-κB activation. Further research into the interaction between LMP1 and CD63 in exosomes may be warranted to understand better the mechanisms underlying exosome-mediated tumor growth and metastasis in nasopharyngeal carcinoma.
In summary, we appreciate the reviewer's suggestions to discuss the work of Aga et al. (2014) and Verweij et al. (2011) in our manuscript, and we believe that their contributions are valuable in enhancing our understanding of the role of LMP1 in nasopharyngeal carcinoma.
Reviewer 3 Report
This is very interesting paper, but need more results to support authors's claim as below.
1. A lot of typo errors (eg., NF-kB) have been found throughout the manuscritipn. Authors need to check. Also, some of gramatical errors are found. Please edit the manuscript by commercial English editing company.
2. Statistical significance should be included in all figures.
3. Legends of Figure 11 should be shorten.
4. Relative intensity figure should be required for Fig. 2. Also, authors should provide a blot showing clearer seperation between LAMP-1 and HC.
5. Authors should provide RT-PCR result to support Fig. 10 results.
6. Protein levels of active forms of NF-kB family observed by immunoblotting should be provided.

Dear Prof. Dr.
Thank you for taking the time to review our manuscript. We appreciate your feedback and would like to respond to each of your valuable comments point-by-point :
We apologize for the typos and grammatical errors in our manuscript. We have carefully reviewed the manuscript and corrected these errors. Additionally, we have consulted with professional English editing software to improve the language quality.
Thank you for your suggestion about statistics. As applicable, we have incorporated statistical significance in the figures and in the text relating to these figures when/where appropriate. In addition, a new section (Statistical analysis) was added to the methods section.
We agree that the legends of Figure 11 were too long and have now shortened them for better readability.
We appreciate your suggestion to include a relative intensity figure for Fig. 2 and to provide a blot showing a clearer separation between LAMP-1 and HC. We have followed your suggestion and updated Fig. 2 accordingly.
Thank you for your comment on Figure 10. The data are expressed as optical densities at 450 nm. The Relative quantification analysis is a method used to compare the ratios of two DNA sequences. The first ratio is the target DNA sequence to a reference DNA sequence in an unknown sample. The second ratio is the same two sequences in a standard sample called a “calibrator”. Additional information on the principle of this quantification is reported in the methods section.
We appreciate your recommendation to include the protein levels of active forms of the NF-kB family. We have now included these data in the revised manuscript.
Once again, thank you for your valuable feedback. We believe that the revisions we have made have significantly improved the quality of our manuscript.
