Abstract

. From previous research, asiaticoside possesses the potential capability to delay skin aging and reduce wrinkles clinically, but its underlying mechanism to regulate aging have not well-investigated. The present study found that asiaticoside could improve the viability and maintains a normal morphology in ultraviolet (UV)-exposure cells. In addition, β-galactosidase release was inhibited by treatment of asiaticoside in UV damaged cells was observed. The present study confirmed that UV-induced ROS generation and SOD reduction could be attenuated by incubation of asiaticoside. By using RNA sequencing technology, differential genes between UV and asiaticoside treatment were demonstrated and enriched genes suggested that asiaticoside is able to negatively regulate cell cycle and MAPK pathways. Western blotting was employed to clarify the variation of key proteins in TGF-β1/Smad pathway and cell cycle and the result implied that asiaticoside is capable of attenuating upregulation of TGF-β1, Smad2 and Smad3 to reverse cell senescence. The present study investigated regulation of asiaticoside to TGF-β1/Smad pathway in UV-induced HaCat cells, showing its potential to against photoaging.

  • Jiang et al. quantified asiaticoside and demonstrated its anti-photoaging potential through TGF-β1/Smad pathway modulation in UV-exposed cells.

    “Likewise, Jiang et al. [20], quantified asiaticoside and demonstrated its anti-photoaging potential through TGF-β1/Smad pathway modulation in UV-exposed cells.”

    The Discussion reports that asiaticoside reduced UV-induced TGF-β1, Smad2 and Smad3 upregulation and showed anti-photoaging effects in cells. The Materials and methods section specifies asiaticoside treatment concentrations, but does not report quantifying asiaticoside itself; that part of the claim is unsupported. (LLM, conf=0.86)

  • Jiang et al. showed that asiaticoside suppressed UV-induced expression of TNF-α and IL-6 in dermal fibroblasts via the TGF-β1/Smad pathway, thereby reducing oxidative and inflammatory stress.

    “Moreover, Jiang et al. [20] showed that asiaticoside suppressed UV-induced expression of TNF-α and IL-6 in dermal fibroblasts via the TGF-β1/Smad pathway, thereby reducing oxidative and inflammatory stress.”

    The Results (Regulation of Asiaticoside on cell signaling pathways) report reduced UV-induced ROS and TGF-β1/Smad2/3 signaling with asiaticoside, as well as reduced expression of the inflammatory protein MMP-9. The paper does not report suppression of TNF-α or IL-6. Its Materials and methods identify the experimental cells as HaCat cells, not dermal fibroblasts. (LLM, conf=0.90)

  • Antioxidant and cytoprotective benefits from C. asiatica are mediated through direct ROS scavenging and upregulation of endogenous antioxidant enzymes such as SOD and catalase.

    “Antioxidant and cytoprotective benefits from C. asiatica are mediated through direct ROS scavenging and upregulation of endogenous antioxidant enzymes such as superoxide dismutase (SOD) and catalase (Zhao et al. 2020; Mohapatra et al. 2021; Jiang et al. 2022).”

    From Centella asiatica (L.) Urb. in skin health and cosmeceuticals: mechanisms, clinical evidence, and advanced delivery systems (2025) · cites this paper as Jiang et al. 2022

    The Results sections on UV-induced ROS and SOD activity report that asiaticoside reduced intracellular ROS and restored SOD activity in UV-exposed cells; the Discussion describes this as scavenging excess ROS. The paper does not establish direct chemical scavenging or show that asiaticoside upregulates catalase: catalase appears only in a general explanation of how superoxide is broken down. Page numbers were not provided for these passages. (LLM, conf=0.88)

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.
