The authors state:
> SPF grade male C57BL/6 rats with age of 7–8 weeks and weight of 23–25 g were purchased from Hubei Provincial Center for Disease Control and Prevention and kept in Experimental Animal Center, Zhongnan Hospital of Wuhan University (SPF grade).
Did the authors mean C57BL/6 mice? C57BL/6 rats do not exist.
We wish to inform the community that the previous comment regarding the mention of “C57BL/6 rats” was posted by an account that has since been permanently blocked from the ScienceGuardiansTM Post-Publication Peer Review Platform due to misuse of Northwestern University’s email system to create a deceptive alias for fraudulent purposes and identity misrepresentation, which constitutes a violation of our terms of conduct.
However, the scientific point raised remains valid. The term “C57BL/6 rats” is indeed incorrect, as C57BL/6 refers exclusively to an inbred mouse strain. This appears to be a genuine typographical or reporting error that warrants clarification.
We encourage the authors and readers to review this detail, and if appropriate, initiate the necessary corrections through the relevant journal channels.
ScienceGuardiansTM remains committed to scientific integrity, ensuring that while misconduct is addressed, valid concerns raised for the betterment of scientific literature are preserved.
Thank you for supporting the continued improvement of academic research.
