EPRS1 and focal segmental glomerulosclerosis: Compared with those in normal controls (Controls), the levels of EPRS1 expression were significantly increased in the kidneys of patients with focal segmental glomerulosclerosis (fibrosis, Fig. 1a, b) accompanied by atrophic tubules (Fig. 1a, c), interstitial fibrosis (Fig. 1a, d), and a decreased estimated glomerular filtration rate (eGFR, Fig. 1e).
