The Study of Myo-Inositol's Anxiolytic Activity on Zebrafish ().

Introduction: Myo-inositol (MI) is the most abundant inositol found in nature. To date MI supplementation is reported to be effective in the treatment of polycystic ovary syndrome, it is also suggested to alleviate the symptoms of diabetes and neurodegenerative disorders, but to date no statistically significant effects of inositol on depressive and anxiety symptoms were proven. In the study of anxiolytic effects in zebrafish, we often use the thigmotaxis index measuring the ratio of the amount of time the animal spends near the walls compared to the entire arena.

Simple Coumarins from Fruits: Evaluation of Anxiolytic Activity and Influence on Gene Expression Related to Anxiety in Zebrafish Model.

Anxiety is one of the most common central nervous system disorders, affecting at least one-quarter of the worldwide population. The medications routinely used for the treatment of anxiety (mainly benzodiazepines) are a cause of addiction and are characterized by many undesirable side effects. Thus, there is an important and urgent need for screening and finding novel drug candidates that can be used in the prevention or treatment of anxiety.

Antiepileptic Properties of Scyllo-Inositol on Pentylenetetrazol-Induced Seizures.

Epilepsy, with about 70 million affected people worldwide, is one of the biggest challenges of medicine today. It is estimated that about one-third of epileptic patients receive inadequate treatment. Inositols have proved effective in many disorders; hence, in the current study, we tested potential antiepileptic properties of scyllo-inositol (SCI)-one of the most common commercially available inositols-in zebrafish larvae with pentylenetetrazol-induced seizures.

Evaluation of the Antiseizure Activity of Endemic Plant Guillaumin and Its Main Constituent, Halfordin, on a Zebrafish Pentylenetetrazole (PTZ)-Induced Seizure Model.

Epilepsy is a neurological disease that burdens over 50 million people worldwide. Despite the considerable number of available antiseizure medications, it is estimated that around 30% of patients still do not respond to available treatment. Herbal medicines represent a promising source of new antiseizure drugs.

MiR92b-3p synthetic analogue impairs zebrafish embryonic development, leading to ocular defects, decreased movement and hatching rate, and increased mortality.

The aim of this study was to examine the effect of microRNA 92b-3p (MiR92b-3p) overexpression on the embryonic development of zebrafish. A synthetic MiR92b-3p analogue (mirVana™ mimic, in vivo-ready) was injected at doses up to 5 ng/embryo into the yolk sac of embryos (2-16 cell stage). At 24 h post fertilization (hpf), the locomotor activity of the embryos was measured, and after hatching (72 hpf), the rates of malformation occurrence, hatching, and mortality were determined.
