Hearing loss is a serious burden to physical and mental health worldwide. Aberrant development and damage of hearing organs are recognized as the causes of hearing loss, the molecular mechanisms underlining these pathological processes remain elusive. Investigation of new molecular mechanisms involved in proliferation, differentiation, migration and(More)
Diazoxide (DZ), a highly selective opener of the mitochondrial ATP-sensitive potassium (mitoK(ATP)) channel, has neuroprotective effects. However, the mechanism of DZ protecting hippocampal neurons against cell death in pilocarpine-induced seizures is unknown. In this study, we investigated DZ attenuating neuronal loss caused by pilocarpine-induced seizures(More)
In this study, we demonstrated a decreased level of mitochondrial DNA (mtDNA) with a large number of oxidized bases in hippocampi of rats with epilepsy induced by pilocarpine. In order to verify the underlying mechanism of mtDNA impairment, we detected the response of antioxidant defense system and mitochondrial base excision repair (mtBER) pathway.(More)
Status epilepticus (SE) can cause severe neuronal loss and oxidative damage. Peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α) can be neuroprotective by inducing the antioxidant system, so we evaluated the role of PGC-1α in SE. The expression of PGC-1α and one of its target genes, uncoupling protein 2 (UCP2), was upregulated after SE,(More)
Correct specification of the left-right (L-R) axis is important for organ morphogenesis. Conserved mechanisms involving cilia rotation inside node-like structures and asymmetric Nodal signaling in the lateral plate mesoderm (LPM), which are important symmetry-breaking events, have been intensively studied. In zebrafish, the clustering and migration of(More)
Oxidative damage to mitochondrial DNA (mtDNA) has been implicated as an important mechanism underlying mitochondrial deficiency in epileptic seizures. In focusing on the role of the DNA repair pathway, we determined the response of the mitochondrial base excision repair (mtBER) pathway in pilocarpine-induced status epilepticus (SE) in hippocampi of male(More)
Parkinson's disease (PD) is characterized by the loss of neuromelanin (NM)-containing neurons in the substantia nigra pars compacta (SNc), and it is divided into two motor subtypes: the postural instability gait difficulty (PIGD) and the tremor dominant (TD) subtypes. With NM-sensitive Magnetic Resonance Imaging (NM-MRI), investigators have been able to(More)
The type II CRISPR/Cas9 system has been used widely for genome editing in zebrafish. However, the requirement for the 5'-NGG-3' protospacer-adjacent motif (PAM) of Cas9 from Streptococcus pyogenes (SpCas9) limits its targeting sequences. Here, we report that a Cas9 ortholog from Staphylococcus aureus (SaCas9), and its KKH variant, successfully induced(More)
Natural products are a rich resource for the discovery of therapeutic substances. By directly using 504 fine fractions from isolated traditional Chinese medicine plants, we performed a transgenic zebrafish based screen for anti-angiogenesis substances. One fraction, DYVE-D3, was found to inhibit the growth of intersegmental vessels in the zebrafish(More)
