Pseudogenization of the Hair-Related Genes PADI3 and S100A3 in Cetaceans and Hippopotamus amphibius.

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.
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
Hair-related genes in mammals play important roles in the development and maintenance of hair and other keratinous structures in mammals. The peptidyl arginine deiminase 3 (PADI3) gene encodes an enzyme that catalyzes the conversion of arginine residues to citrulline. The S100 calcium binding protein A3 (S100A3) gene encodes a protein that is highly expressed in the hair cuticle and contains arginine residues that are converted to citrullines by PADI enzymes. In this study, we investigated the pseudogenization events of PADI3 and S100A3 in cetaceans and Hippopotamus amphibius. We found that PADI3 underwent three independent pseudogenization events during cetacean evolution, in baleen whales, toothed cetaceans other than Physeter catodon, and P. catodon. Notably, the entire PADI3 gene is absent in the baleen whales. Pseudogenization of S100A3 occurred independently in cetaceans and H. amphibius. Interestingly, we found that in cetaceans S100A3 underwent pseudogenization before PADI3, suggesting that differential selection pressures were acting on the two genes. Our findings provide valuable insights into the molecular evolution of these genes in cetaceans and hippopotamuses, highlighting their importance for understanding the evolution of hair-related genes.
