Abstract

Melatonin, a hormone secreted by the pineal gland, possesses multiple biological activities such as antitumor, antioxidant, and anti‐ischemia. C‐kit+ cardiac progenitor cells (CPC s) have emerged as a promising tool for the treatment of heart diseases. However, the senescence of CPC s due to pathological stimuli leads to the decline of CPC s' functions and regenerative potential. This study was conducted to demonstrate whether melatonin antagonizes the senescence of CPC s in response to oxidative stress. Here, we found that the melatonin treatment markedly inhibited the senescent characteristics of CPC s after exposed to sublethal concentration of H 2 O 2, including the increase in senescence‐associated β‐galactosidase (SA‐β‐gal)‐positive CPC s, senescence‐associated heterochromatin loci (SAHF), secretory IL‐6 level, and the upregulation of p53 and p21 proteins. Senescence‐associated proliferation reduction was also attenuated by melatonin in CPC s. Luzindole, the melatonin membrane receptor blocker, may block the melatonin‐mediated suppression of premature senescence in CPC s. Interestingly, we found that long noncoding RNA H19 and its derived miR‐675 were downregulated by H 2 O 2 in CPC s, but melatonin treatment could counter this alteration. Furthermore, knockdown of H19 or miR‐675 blocked antisenescence actions of melatonin on H 2 O 2‐treated CPC s. It was further verified that H19‐derived miR‐675 targeted at the 3′UTR of USP 10, which resulted in the downregulation of p53 and p21 proteins. In summary, melatonin antagonized premature senescence of CPC s via H19/miR‐675/USP 10 pathway, which provides new insights into pharmacological actions and potential applications of melatonin on the senescence of CPC s.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Melatonin decreases p53, p21, and p16 proteins and enhances SIRT1 activity in H2O2-induced senescence.

    “Melatonin-induced decrease in p53, p21 and p16 proteins, together with enhanced SIRT1 activity, have also been reported in the context of H2O2-induced senescence [458,459].”

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.
