Berberine enhances autophagic flux to alleviate ischemic neuronal injury by facilitating N-ethylmaleimide-sensitive factor-mediated fusion of autophagosomes with lysosomes.

Our previous study demonstrated that Berberine (BBR) significantly enhances autophagic flux, alleviating ischemic neuronal injury by restoring autolysosomal function, but how BBR augmented autolysosomal functions remained elusive. N-ethyl-maleimide sensitive factor (NSF) is considered as a major ATPase to reactivate soluble NSF attachment protein receptors (SNAREs), which directly mediate autophagosome-lysosome fusion. However, NSF was dramatically inactivated by ischemia to hamper membrane-membrane fusion, leading to autophagic/lysosomal dysfunction in neurons.

Current trends of high-risk gene Cul3 in neurodevelopmental disorders.

Cul3 encodes Cullin-3, a core component of the ubiquitin E3 ligase that is involved in protein ubiquitination. Recent studies have identified Cul3 as a high-confidence risk gene in neurodevelopmental disorders (NDDs), especially autism spectrum disorder (ASD). Different strategies have been used to generate animal models with Cul3 deficiency in the central nervous system, including whole-brain knockout (KO), cell-type specific conditional KO (cKO), and brain region-specific knockdown.

CTNNB1 in neurodevelopmental disorders.

CTNNB1 is the gene that encodes β-catenin which acts as a key player in the Wnt signaling pathway and regulates cellular homeostasis. Most CTNNB1-related studies have been mainly focused on its role in cancer. Recently, CTNNB1 has also been found involved in neurodevelopmental disorders (NDDs), such as intellectual disability, autism, and schizophrenia.

miR-92a-2-5p Regulates the Proliferation and Differentiation of ASD-Derived Neural Progenitor Cells.

Autism spectrum disorder (ASD) is a group of complex neurodevelopmental disorders with abnormal behavior. However, the pathogenesis of ASD remains to be clarified. It has been demonstrated that miRNAs are essential regulators of ASD.
