However, it remains unclear which specific genes are involved in the pathogenesis of HFM. By identifying differentially expressed genes (DEGs) in deficient facial adipose tissue from HFM patients, we hope to provide a new insight into disease mechanisms from the transcriptome perspective. RNA sequencing (RNA-Seq) was performed with 10 facial adipose tissues from patients of HFM and healthy controls. Differentially expressed genes in HFM were validated by quantitative real-time PCR (qPCR). Functional annotations of the DEGs were analyzed with DESeq2 R package (1.20.0). A total of 1,244 genes were identified as DEGs between HFM patients and matched controls. Bioinformatic analysis predicted that the increased expression of <jats:italic>HOXB2<\/jats:italic> and <jats:italic>HAND2<\/jats:italic> were associated with facial deformity of HFM. Knockdown and overexpression of <jats:italic>HOXB2<\/jats:italic> were achieved with lentiviral vectors. Cell proliferation, migration, and invasion assay was performed with adipose-derived stem cells (ADSC) to confirm the phenotype of <jats:italic>HOXB2<\/jats:italic>. We also found that PI3K\u2212Akt signaling pathway and human papillomavirus infection were activated in HFM. In conclusion, we discovered potential genes, pathways and networks in HFM facial adipose tissue, which contributes to a better understanding of the pathogenesis of HFM.<\/jats:p>","DOI":"10.3389\/fped.2023.1099841","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T06:48:13Z","timestamp":1676270893000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Transcriptome
