PIGOME: An Integrated and Comprehensive Multi-omics Database for Pig Functional Genomics Studies
biorxiv(2024)
Abstract
In addition to being a major source of animal protein, pigs are important model for the study of development and diseases in humans. During the past two decades, thousands of high-throughput sequencing studies in pigs have been performed using a variety of tissues from different breeds and developmental stages. However, the multi-omics database specifically used for pig functional genomic research is still limited. Here, we present a user-friendly database of pig multi-omics named PIGOME. PIGOME contains seven types of pig omics datasets, including whole-genome sequencing, RNA-seq, miRNA-seq, ChIP-seq, ATAC-seq, bisulfite-seq, and MeRIP-seq, from 6,901 samples and 392 projects with manually curated metadata, integrated gene annotation, and quantitative trait locus information. Furthermore, various ‘explore and browse’ functions have been established for user-friendly access to omics information. PIGOME implemented several tools to visualize genomic variants, gene expression, and epigenetic signals of a given gene in the pig genome, enabling efficient exploration of spatial-temporal expression/epigenetic pattern, function, regulatory mechanism, and associated economic traits. Collectively, PIGOME provides valuable resources for pig breeding and is helpful for human biomedical research. PIGOME is available at .
