Abstract

Enzymatic hydrolysates from Oysters (OAH) display multiple biological activities. Previously, a 3~5 KDa oyster ultrafiltration component (OUP) showed a high property of preventing skin oxidation. Subsequently, we identified specific peptides with such activity. OUP was fractionated stepwise by Sephadex-G25 and RP-HPLC, and active fractions were screened using UV-irradiated HaCaT cells. The most active fractions (OP5-3) were analyzed by LC-MS/MS and a total of 17 peptides were identified. Results from mass spectrometry showed that OP5-3 consisted of peptides with a molecular weight range of 841.51–1786.92 Da. Six of these peptides were synthesized for validating the activity of resisting skin oxidation in the same cell model. All six peptides showed varying degrees of antioxidant activity, while pretreatment of HaCaT cells with AIVAEVNEAAK alleviated UV cytotoxicity, inhibited metalloproteinase 1 (MMP-1) expression, and showed the highest activity to resist UV-induced skin photo-oxidation among these peptides. In addition, results from molecular docking analysis of MMP-1 with AIVAEVNEAAK showed that AIVAEVNEAAK suppresses its enzymatic activity by directly interacting with MMP-1 and thus exhibit anti-photoaging activity.

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

  • Zhang et al. found that peptides derived from Crassostrea Hongkongensis improved cell viability and reduced oxidative stress markers in UV-exposed HaCaT cells.

    “The researchers found that these novel antioxidant peptides were able to improve cell viability and reduce oxidative stress markers in UV‐exposed cells, indicating their potential as protective agents against photodamage.”

    From Cosmeceuticals in photoaging: A review. (2024) · cites this paper as [55]

  • Zhang et al.'s study has relatively low level of evidence because it is an in vitro study on HaCaT cells.

    “However, the level of evidence for this study is relatively low according to the Oxford Centre for Evidence‐Based Medicine's hierarchy of evidence, as it is an in vitro study conducted on HaCaT cells.”

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.
