Via the miR-34a-5p/sirtuin 1 (SIRT1)/HIF-1α pathway, long intergenic noncoding RNA (lincRNA) 1700020I14Rik suppresses expression of renal fibrosis biomarkers, inhibits mesangial cell proliferation under diabetic conditions, and is involved in progression of DN [49]. Here, HIF1A is linked to renal fibrosis.
