Genomics data do not intersect and are therefore not represented in the Table 4 . There are many types of non-coding RNAs while few related transcriptomic studies, the sequencing results cannot be intersected. C2ORF54, chromosome 2 open reading frame 54; TMEM161B, transmembrane protein 161B; TBX3, T-box transcription factor 3; SKI, v-ski avian sarcoma viral oncogene homolog; TAL1, T-cell acute lymphocytic leukemia 1; GPR137B, G protein-coupled receptor 137B; ITGA4, integrin subunit alpha 4; APC, adenomatosis polyposis coli; CDKN1C, cyclin dependent kinase inhibitor 1C; MEG3, maternally expressed 3; PLAGL1, pleiomorphic adenoma gene-like 1; IFI44L, interferon induced protein 44 like; IFIT1, interferon induced protein with tetratricopeptide repeats 1; TNFRSF21, TNF receptor superfamily member 21; MMP26, matrix metallopeptidase 26; ALB, albumin; NACA4P, putative nascent polypeptide-associated complex subunit alpha-like protein; KRT2, type II cytoskeletal 2 epidermal; FARSA, phenylalanine–tRNA ligase alpha subunit; CAT, catalase; TUBA8, tubulin alpha-8 chain; ITIH4, inter-alpha-inhibitor heavy chain 4; IGFBP4, insulin-like growth factor-binding protein 4.
