During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identify individuals and their parents. Genetic diagnostics generally include the analysis of related animals. In this work, the degree of information provided by SNPs for a consanguineous herd of cattle was compared with that provided by STRs. Thirty-six closely related Angus cattle were genotyped for 18 STRs and 116 SNPs. Cumulative SNPs exclusion power values (Q) for paternity and sample matching probability (MP) yielded values greater than 0.9998 and 4.32E(-42), respectively. Generally 2-3 SNPs per STR were needed to obtain an equivalent Q value. The MP showed that 24 SNPs were equivalent to the ISAG (International Society for Animal Genetics) minimal recommended set of 12 STRs (MP ∼ 10(-11)). These results provide valuable genetic data that support the consensus SNP panel for bovine genetic identification developed by the Parentage Recording Working Group of ICAR (International Committee for Animal Recording).

Identifying and quantifying the dominant factors influencing heavy metal (HM) pollution sources are essential for maintaining soil ecological health and implementing effective pollution control measures. This study analyzed soil HM samples from 53 different land use types in Jiaozuo City, Henan Province, China. Pollution sources were identified using Absolute Principal Component Score (APCS), with 8 anthropogenic factors, 9 natural factors, and 4 soil physicochemical properties mapped using Geographic Information System (GIS) kernel density estimation.

This study identifies microRNAs (miRNAs) with significant discriminatory power in distinguishing melanoma from nevus, notably hsa-miR-26a and hsa-miR-211, which have exhibited diagnostic potential with accuracy of 81% and 78% respectively. To enhance diagnostic accuracy, we integrated miRNAs into various machine-learning (ML) models. Incorporating miRNAs with AUC scores above 0.

In the past years, dogs have served as a convenient natural model organism for longevity due to their similarity with humans concerning not only their environment but also the diseases and complications occurring in older age. Since many dog breeds have significantly shorter lifespan than their closely related breeds, identification of genes associated with longevity may help to elucidate its background and serve as a possible tool for selective breeding of long-living dogs. This genome-wide association study (GWAS) was undertaken to identify the candidate genes associated with longevity in Cavalier King Charles Spaniel individuals that have reached the age of more than 13 years.

Background: Alagille syndrome (ALGS) is a rare disease. The variable clinical manifestations make the diagnosis of ALGS difficult. This study aimed to provide a basis for the early diagnosis of ALGS patients whose clinical identification is difficult and to enrich the spectrum of genetic variants implicated in Chinese children with ALGS.

Unlabelled: Orphan genes (OGs), also known as lineage-specific genes, are species-specific genes that play a crucial role in species-specific adaptations to various stresses. Although OGs have been identified in several plant species, there is no information on OGs in banana genomes. This study aimed to systematically identify OGs in twelve banana (sub)species using comparative genomics.
