Abstract

Activation of quiescent hepatic stellate cells (HSCs) is the major event in liver fibrosis, along with enhancement of cell proliferation and overproduction of extracellular matrix. Recent findings suggest that senescence of activated HSCs might limit the development of liver fibrosis. The p53, a guardian of the genome is associated with liver fibrosis, has been shown to regulate HSCs senescence. In this study, we report that microRNA‐145 (miR‐145) and p53 were downregulated in vivo and in vitro, concomitant with the enhanced expression of zinc finger E‐box binding homeobox 2 (ZEB2). In addition, overexpression of miR‐145 and p53 led to upregulation of the number of senescence‐associated β‐galactosidase‐positive HSCs and the expression of senescence markers p16 and p21, along with the reduced abundance of HSC activation markers α‐smooth muscle actin and type I collagen in activated HSCs. Furthermore, silencing of ZEB2 promoted senescence of activated HSCs. Moreover, we also demonstrated that miR‐145 specifically targeted the 3′‐untranslated regions of ZEB2. In vitro promoter regulation studies show that ZEB2 could bind to the E‐box of the p53 promoter as well as inhibit its promoter activity and thus suppress the expression of p53, which in turn repressed activated HSCs senescence. Taken together, our results describe a novel miR‐145‐ZEB2‐p53 regulatory line might participate in the senescence of activated HSCs and might carry potential therapeutic targets for restraining liver fibrosis.

  • Downregulation of ZEB2 promotes cell senescence in hepatic stellate cells and dermal fibroblasts, limiting fibrosis.

    “In support of this concept, there is evidence that the downregulation of the Zn-finger protein ZEB2 significantly promotes cell senescence in hepatic stellate cells and dermal fibroblasts, limiting the development of fibrosis [435,436].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
