    CDK5 plays an important role in neurotransmission in the normal function of the adult brain, and dysregulation can lead to Tau hyperphosphorylation and cognitive impairment. Our findings suggest that p35/Rac1 signaling is critical in the CDK5 shRNAmiR-induced neuroprotection against glutamate neurotoxicity and is also correlated with the recovery of cognitive function in 3xTg-AD mice. CDK5 shRNAmiR blocks calpain activation, and the cleavage of p35 to p25 produced by glutamate, which generates neuroprotection in a p35 up-regulation dependent mode and its down-stream control of Rho GTPases, such as Rac1 and RhoA.

  3. Nidogen-1 is a common target of microRNAs MiR-192/215 in the pathogenesis of Hirschsprung's disease

    We proposed the following cascade for the proposed mechanism of miR-192/215 in the pathogenesis of Hirschsprung disease (HSCR) by targeting Nidogen 1 (NID1). Aberrant expression of miR-192/215 inhibits cell migration and cell proliferation via NID1. We think the miR-192/miR-215/NID1 signaling pathway may play an important role in the pathogenesis of HSCR.

  4. Postnatal ethanol exposure alters levels of 2-arachidonylglycerol-metabolizing enzymes and pharmacological inhibition of monoacylglycerol lipase does not cause neurodegeneration in neonatal mice

    The consumption of ethanol by pregnant women may cause neurological abnormalities, affecting learning and memory processes in children, and are collectively described as fetal alcohol spectrum disorders (FASDs). In our study, ethanol treatment of postnatal day 7 (P7) mice significantly enhanced the levels of the developmentally relevant endocannabinoids anandamide (AEA) but not 2-arachidonylglycerol (2-AG), and induced widespread neurodegeneration, yet the reason for the lack of effects of ethanol on the 2-AG level is unknown. Here, the ethanol treatment of P7 mice causes the specific up-regulation of AEA-CB1R signaling over the 2-AG-CB1R pathway by the specific reorganization of the enzymes that synthesize (DAGL-α/β) and degrade (MAGL) 2-AG. This study demonstrates the neuro-regulatory role of 2-AG metabolizing enzymes in ethanol-induced neurodegeneration in neonatal mice.
