Similarly, other studies have explored the functions of five lncRNAs (ZFAS1, GAS5, LINC00941, MEG3, and ATB) in the occurrence and development of PF (Liu et al., 2020; Yang et al., 2020; Xu et al., 2021; Gao et al., 2022; Zhang et al., 2022) and found that their expression levels were highly correlated with the differentiation of PF fibroblasts and epithelial-mesenchymal transition. The gene discussed is MEG3; the disease is pemphigus foliaceus.
