1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundRoyal Jelly (RJ) is widely used in cosmetics for its beneficial skin effects, but its impact on cellular senescence remains unclear. Senomorphic agents that suppress the senescence-associated secretory phenotype (SASP) offer safe therapeutic strategies for skin aging. This study investigates the senomorphic effects of RJ on epidermal senescence. METHODS AND

resultsWe utilized an in vitro replicative senescence model of normal human epidermal keratinocytes, validating our findings with cells from chronologically aged adult donors, including a 75-year-old. Results demonstrated that RJ significantly suppresses multiple SASP factors, including interleukin (IL)-6 and C-X-C motif ligand (CXCL) family members, in both models without inducing cytotoxicity. Mechanistically, RNA-sequencing revealed that senescence upregulated pro-inflammatory factors via TNF-α and NF-κB signaling pathways. RJ acts as a multitarget senomorphic agent, inhibiting these senescence-activated pathways and reducing oxidative stress.

conclusionsRJ is a potent natural senomorphic agent capable of modulating complex SASP networks. It provides valuable insights into potential strategies for mitigating skin inflammation and preserving youthfulness.
