Effects of two chd2-knockout strains on the morphology and behavior in zebrafish.

The chromodomain helicase DNA binding domain 2 (CHD2) gene is an ATPase and a member of the SNF2-like family of helicase-related enzymes. CHD2 plays critical roles in human brain development and function, and homozygous mutation of Chd2 in mice results in perinatal lethality. To further elucidate the effects of chd2, we used CRISPR/Cas9 to create two chd2-knockout strains (fdu901, 11,979-11982delGGGT, and fdu902, 27350delG) in zebrafish.

Sound shock response in larval zebrafish: A convenient and high-throughput assessment of auditory function.

Given that hearing ability can be challenged in diverse ways, it is necessary to develop an easily conducted, high-throughput method for assessing potential auditory risks. Measuring the acoustic startle response (ASR) has become a critical behavioral method in hearing research using zebrafish (Danio rerio). In this study, changes in the activity of zebrafish larvae (10 days post fertilization (dpf)) due to exposure to a sudden easily-generated broad-band noise were automatically and objectively recorded and analyzed without building sophisticated equipments.

Behavioural responses of zebrafish larvae to acute ethosuximide exposure.

The anticonvulsant drug ethosuximide has shown diverse anxiety-related activity in rodents, but research in zebrafish is limited. To evaluate the effects of acute ethosuximide exposure on locomotor activity and anxiety-related thigmotaxis behaviours of zebrafish larvae, the activity of AB strain zebrafish larvae at 5 and 7 days postfertilization (dpf) was analysed under normal constant illumination and stressful light-dark transitions. Under constant illumination, ethosuximide at concentrations of 2, 5 and 10 mmol/l increased the distances travelled and intensified locomotor responses to a novel environment.

ARID1A gene silencing reduces the sensitivity of ovarian clear cell carcinoma to cisplatin.

In ovarian clear cell carcinoma (OCCC), the mutation rate of the AT-rich interaction domain 1A (ARID1A) gene is 46-57%. However, the effects of ARID1A gene silencing by small interfering RNA (siRNA) on the sensitivity of OCCC to cisplatin have not been investigated. Thus, this study aimed to elucidate the association between ARID1A gene silencing and drug resistance in OCCC.

Social Preference Deficits in Juvenile Zebrafish Induced by Early Chronic Exposure to Sodium Valproate.

Prenatal exposure to sodium valproate (VPA), a widely used anti-epileptic drug, is related to a series of dysfunctions, such as deficits in language and communication. Clinical and animal studies have indicated that the effects of VPA are related to the concentration and to the exposure window, while the neurobehavioral effects of VPA have received limited research attention. In the current study, to analyze the neurobehavioral effects of VPA, zebrafish at 24 h post-fertilization (hpf) were treated with early chronic exposure to 20 μM VPA for 7 h per day for 6 days or with early acute exposure to 100 μM VPA for 7 h.

Anxiety-related behavioral responses of pentylenetetrazole-treated zebrafish larvae to light-dark transitions.

Pentylenetetrazole (PTZ), γ-aminobutyrate (GABA) antagonist, is a convulsant drug, known to induce anxiety and seizures in zebrafish.
