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

Polydeoxyribonucleotide (PDRN) is a low molecular weight linear polyribonucleotide fragment derived from salmon sperm, known for its potential in tissue regeneration and anti-inflammatory applications. However, its specific function in cellular senescence is yet to be fully understood. Silent information regulator 1 (SIRT1), an NAD + -dependent deacetylase, plays a crucial role in regulating cellular aging and tumorigenesis. Notably, SIRT1 levels decrease with age in both mice and during cellular senescence, highlighting its significance in anti-aging processes. This study assessed the effects of PDRN on cellular aging induced by ultraviolet B (UVB) or hydrogen peroxide (H2O2) and investigated the mechanisms of its protective effects against aging at the cellular level. Our data demonstrated that PDRN treatment mitigated the decline in cell viability and inhibited cell aging when exposed to UVB or H2O2. Furthermore, PDRN ameliorated UVB-induced epidermal thickening in mouse skin. Mechanically, we found that PDRN treatment led to a reduction in nuclear autophagy and the formation of cytoplasmic stress granules by preventing the accumulation of damaged LC3 in the nuclear and inhibiting the degradation of SIRT1 and p62 in the cytoplasm during cellular senescence. In conclusion, PDRN exhibits antioxidant and anti-aging properties by diminishing autophagy and enhancing SIRT1 expression. These results suggest that PDRN has potential as a therapeutic compound for reducing skin aging induced by UVB or H2O2 through the modulation of SIRT1 levels.
