Abstract

Scope: S ‐Allylcysteine (SAC) is the most abundant organosulfur molecule derived from aged garlic. The effects ofSAC on improving Aging in naturally aged C57BL/6J male mice and mitochondrial dynamics in Caenorhabditis elegans and its underlying mechanisms is evaluated. Methods and Results: When mice have attained reproductive senescence at 60 weeks of age, SAC is supplemented to 0.05% and 0.2% into their normal diet for 12 weeks. The results show that SAC could significantly improve the level of hepatic optic atrophy 1 ( OPA1 ) mRNA, which is a key factor for mitochondrial fusion, and consequently elevated the mitochondrial biogenesis‐related proteins sirtuin 1 (SIRT1) and peroxisome proliferator‐activated receptor‐gamma coactivator‐1 alpha (PGC‐1α), thus ameliorating oxidative stress, such as malondialdehyde (MDA) in the liver and 8‐hydroxy‐2'‐deoxyguanosine (8‐OHdG) in urine. Among the biochemical markers of aging, SAC significantly reduces liver galactosidase β1 (GLB1) and senescence‐associated β‐galactosidase (SA‐βgal), which are induced by replicative senescence. The mitochondria with green fluorescent protein (GFP)‐tagged transgenic strain SJ4103 C. elegans is incubated with 5 or 50 µM SAC, and SAC treated groups maintain the linear morphology of mitochondria. Conclusion: SAC regulates mitochondrial dynamics and ameliorated aging to a significant degree. This study also confirms that mitochondrial dynamics are a promising target for screening materials to combat aging and as a direction for anti‐aging product development.

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.
