Fig. 5. The interplay of miRNAs and transcription factors (TFs) in regulating autophagy in the fatty liver.

Fig. 5

miR-30b-5p and miR-34a downregulate autophagy-related gene expression by directly inhibiting TFs, such as transcription factor EB (TFEB), Hnf4α, peroxisome proliferator-activated receptor alpha (PPARα), and NAD-dependent protein deacetylase sirtuin 1 (SIRT1). Liver X receptor-α (LXRα) transcriptionally activates miR-34a and let7a, which directly target the 3’UTR of Atg4B and Rab8b. miR-214-3p and HNF4α reciprocally regulate Ulk1 expression.
