PAX7 and neoplasm: Although no studies have yet proven the effect of PAX7 on the metastasis ability of tumour cells, we found that the functional enrichment of DEGs obtained by high‐throughput sequencing after PAX7 knockout showed that these DEGs mainly enriched biological processes and molecular functions related to tumour metastasis ability, such as negative regulation of cell adhesion, cell–cell junction, and actin cytoskeleton.
