关键词: Deoxyshikonin Rotavirus Autophagy Oxidative stress SIRT1/FoxO1/Rab7

摘要:
Rotavirus (RV) is a double-stranded RNA virus. RV prevention and treatment remain a major public health problem due to the lack of clinically specific drugs. Deoxyshikonin is a natural compound isolated from the root of Lithospermum erythrorhizon and one of the shikonin derivatives which owns remarkable therapeutic effects on multiple diseases. The purpose of this research was to inquire Deoxyshikonin's role and mechanism in RV infection.Deoxyshikonin's function in RV was estimated using Cell Counting Kit-8 analysis, cytopathic effect inhibition assay, virus titer determination, quantitative real-time PCR, enzyme linked-immunosorbent assay, Western blot, immunofluorescence, and glutathione levels detection. Also, Deoxyshikonin's mechanism in RV was appraised with Western blot, virus titer determination, and glutathione levels detection. Moreover, Deoxyshikonin's function in RV in vivo was determined using animal models, and diarrhea score analysis.Deoxyshikonin owned anti-RV activity and repressed RV replication in Caco-2 cells. Furthermore, Deoxyshikonin reduced autophagy and oxidative stress caused by RV. Mechanistically, Deoxyshikonin induced low protein levels of SIRT1, ac-Foxo1, Rab7, VP6, low levels of RV titers, low autophagy and oxidative stress. SIRT1 overexpression abolished the effects of Deoxyshikonin on RV-treated Caco-2 cells. Meanwhile, in vivo research affirmed that Deoxyshikonin also possessed anti-RV function, and this was reflected in increased survival rate, body weight, GSH levels, and decreased diarrhea score, RV virus antigen, LC-3II/LC3-I.Deoxyshikonin reduced RV replication through mediating autophagy and oxidative stress via SIRT1/FoxO1/Rab7 pathway.Copyright © 2023 Elsevier Ltd.
