Consistent with our previous study performed with CRISPR/Cas9, a "core" sequence region that is highly sensitive to target mutation was characterized. The region is of 4-nucleotide long, located from +4 to +7 position of the target site, and positioned within a positively charged central channel when assembled into Cpf1 endonuclease. Single-nucleotide mutation at the core sequence could abolish gene editing mediated by a however active sgRNA. With a great majority of the target sites, a kind of 'super' off-target gene editing was observed with both CRISPR/Cpf1 and CRISPR/Cas9. For a given target site, mutation at certain positions led to greatly enhanced off-target gene editing efficacy, even up to 10-fold of that of the fully-matched target. Study further found that these effects were determined by the identity of target nucleotide, rather than the nucleotide of crRNA. This likely suggests that the interactions between target nucleotide and the endonuclease are involved in this process.Autophagy is essential for cellular survival and energy homeostasis under nutrient deprivation. Despite the emerging importance of nuclear events in autophagy regulation, epigenetic control of autophagy gene transcription remains unclear. Here, we report fasting-induced Fibroblast Growth Factor-21 (FGF21) signaling activates hepatic autophagy and lipid degradation via Jumonji-D3 (JMJD3/KDM6B) histone demethylase. Upon FGF21 signaling, JMJD3 epigenetically upregulates global autophagy-network genes, including Tfeb, Atg7, Atgl, and Fgf21, through
