The Vulpes vulpes montana genome provides insights into high-altitude adaptation mechanisms of the Vulpes species.

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
Vulpes vulpes montana (V. v. montana) and Vulpes ferrilata (V. ferrilata) are the only two Vulpes species known to inhabit the Qinghai-Xizang Plateau. Exploring the high-altitude (HA) adaptation mechanisms in Vulpes species may broaden our understanding of the genetic adaptability of species to HA environments. In this study, we constructed a high-quality chromosome-level genome for V. v. montana. The assembled genome was ~2.34 Gb and N50 length of 139.03 Mb, and 99.51% (~2.33 Gb) of the assembly was anchored into 17 pseudo-chromosomes. A total of 20,056 protein-coding genes were predicted in the assembled genome, 93.06% of which were functionally annotated. Comparative genomics analysis reveals unique and shared HA adaptation mechanisms in HA Vulpes species. Further, we identified a parallel amino acid site substitution (Serine to Phenylalanine) at position 132 in the IGSF22 gene that is present in HA Vulpes species. This mutation significantly enhances the expression of this immune-related gene under hypoxic conditions and also markedly up-regulates the expression of genes associated with angiogenesis (AKT1, ABCG2 and VEGFA). Our study reveals the molecular mechanism of HA adaptation in Vulpes species and provides a high-quality genomic resource for future research.
