Abstract

Mesenchymal stem cells ( MSC s) represent an attractive source for stem cell‐based regenerative therapy, but they are vulnerable to oxidative stress‐induced premature senescence in pathological conditions. We previously reported antioxidant and antiarthritic effects of melatonin on MSC s against proinflammatory cytokines. In this study, we hypothesized that melatonin could protect MSC s from premature senescence induced by hydrogen peroxide (H 2 O 2 ) via the silent information regulator type 1 ( SIRT 1)‐dependent pathway. In response to H 2 O 2 at a sublethal concentration of 200 μ m , human bone marrow‐derived MSC s ( BM ‐ MSC s) underwent growth arrest and cellular senescence. Treatment with melatonin before H 2 O 2 exposure cannot significantly prevent premature senescence; however, treatment with melatonin subsequent to H 2 O 2 exposure successfully reversed the senescent phenotypes of BM ‐ MSC s in a dose‐dependent manner. This result was made evident by improved cell proliferation, decreased senescence‐associated β ‐galactosidase activity, and the improved entry of proliferating cells into the S phase. In addition, treatment with 100 μ m melatonin restored the osteogenic differentiation potential of BM ‐ MSC s that was inhibited by H 2 O 2 ‐induced premature senescence. We also found that melatonin attenuated the H 2 O 2 ‐stimulated phosphorylation of p38 mitogen‐activated protein kinase, decreased expression of the senescence‐associated protein p16 INK 4 α , and increased SIRT 1. Further molecular experiments revealed that luzindole, a nonselective antagonist of melatonin receptors, blocked melatonin‐mediated antisenescence effects. Inhibition of SIRT 1 by sirtinol counteracted the protective effects of melatonin, suggesting that melatonin reversed the senescence in cells through the SIRT 1‐dependent pathway. Together, these findings lay new ground for understanding oxidative stress‐induced premature senescence and open perspectives for therapeutic applications of melatonin in stem cell‐based regenerative medicine.

  • 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.
