ABSTRACT
OBJECTIVE:
To unravel the role of La ribonucleoprotein 7 (LARP7), a transcriptional regulator, in the progression of psoriasis and the underlying molecular mechanisms.METHODS:
The psoriasis-like mice model was created by daily administering of imiquimod on shaved skin. The histological analysis and skin damage were evaluated in each group. The inflammation and oxidative stress response were assessed by enzyme-linked-immunosorbent serologic and immunoblot assays. The involvement of silent information regulator 1 (member of the Sirtuin family; SIRT1/nuclear factor kappa B (NF-κB) signaling pathway in LARP7-mediated psoriasis progression was also detected by immunoblot assay.RESULTS:
LARP7 relieved psoriasis symptoms in the mice model. LARP7 inhibited the expression of inflammatory cytokines as well as chemokines in psoriasis-like skin tissues. Additionally, LARP7 suppressed oxidative stress in the psoriasis-like skin tissues of mice. LARP7 inhibited the activation of the SIRT1/NF-κB signaling pathway, and therefore affected the progression of psoriasis.CONCLUSION:
LARP7 relieved psoriasis symptoms in mice by regulating the SIRT1/NF-κB signaling pathway.Palavras-chave
