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

Skin photoaging results primarily from chronic ultraviolet (UV) exposure, which disrupts dermal homeostasis and promotes cellular senescence. Dermal papilla cell-conditioned medium (DPC-CM) has emerged as a promising cell-free approach for skin rejuvenation. This study aimed to explore the anti-photoaging effects of DPC-CM and its potential regulation of ferroptosis. Mouse dermal papilla cells and skin fibroblasts were isolated and characterized. A photoaging model was established using UVA-irradiated fibroblasts, followed by treatment with DPC-CM at two concentrations, the ferroptosis inhibitor ferrostatin-1 (FER-1), or retinoic acid. UVA exposure led to reduced cell viability, impaired migration, increased senescence, elevated iron and reactive oxygen species levels, decreased glutathione, and altered expression of ferroptosis-related markers including nuclear factor erythroid 2-related factor 2 (NRF2), glutathione peroxidase 4 (GPX4), and solute carrier family 7 member 11 (SLC7A11). These changes were partially reversed by DPC-CM and FER-1. Proteomic analysis revealed that proteins in both dermal papilla cells and DPC-CM are associated with ferroptosis pathways. In vivo, DPC-CM significantly attenuated UVA-induced dermal aging. Collectively, these findings demonstrate that DPC-CM protects against photoaging by modulating ferroptosis, supporting its therapeutic potential in oxidative stress-related skin disorders.
