Potentialagents for the treatment of IPF may be non-coding RNAs.It was found that lncRNA PCAT29 (prostate cancer-associatedtranscript 29), which activates miRNA-221 and suppressesTGF-β, can be used to treat patients with IPF (Liu X. et al.,2018). The gene discussed is PPIB; the disease is idiopathic pulmonary fibrosis.
