Rabinovich et al. find that the expression of three genes serine/threonine kinase 17b (STK17B), serine/threonine kinase 3 (STK3), and histone cluster 1 H2ah (HIST1H2AH) with hypomethylated promoters is increased in IPF lungs (Lee et al., 2019). This evidence concerns the gene STK17B and idiopathic pulmonary fibrosis.
