TNF and COVID-19: The GSEA results suggested that chondrocyte precursor, adipocyte precursor and osteoblast precursor were co-enriched in pathways related to “ribosome”, “coronavirus disease-COVID-19”, chondrocyte precursor and osteoblast precursor showed co-enrichment in “MAPK signaling pathway”, “TNF signaling pathway” and “osteoclast differentiation”, adipocyte precursor and osteoblast precursor exhibited co-enrichment in “oxidative phosphorylation”, “parkinson disease”, “huntington disease”, “thermogenesis”, and “cardiac muscle contraction” (Figures 7D–F).
