Identification of as a functional regulator of visceral fat deposition and distribution.

Ectopic deposition of visceral adipose tissue (VAT) in abdomen is usually accompanied with systematic chaos of energy metabolism, a higher risk of cardiovascular diseases and type II diabetes. Here, we identified a previously unexplored gene as a master regulator of fat distribution, which alone plays a significant role in determining the VAT accumulation. Firstly, zebrafish had the highest homology with human compared to other s in mouse and rat.

Efficacy and Safety of Tirofiban in Clinical Patients With Acute Ischemic Stroke.

Background: Intravenous thrombolysis and endovascular thrombectomy have been approved for acute ischemic stroke (AIS). However, only a minority of patients received these treatments in China. We aimed to evaluate the efficacy and safety of tirofiban in patients with AIS who were not undergoing early recanalization treatments.

Zonular defects in loxl1-deficient zebrafish.

Background: To investigate the roles of the lysyl oxidase-like 1 (loxl1) gene in zebrafish eye development and the potency of loxl1 deficiency in mimicking the ocular manifestations of exfoliation syndrome (XFS).

Methods: CRISPR/Cas9 technology was used to generate a frameshift coding deletion in zebrafish loxl1. Expression profiles and ocular manifestations of the wildtype, heterozygous mutant (loxl1 ) and homozygous mutant (loxl1 ) zebrafish were analysed in a range of developmental stages from zebrafish larvae to dissected adult zebrafish eyes.

Altered DNA methylation pattern reveals epigenetic regulation of Hox genes in thoracic aortic dissection and serves as a biomarker in disease diagnosis.

Acute exposure to N-Ethylpentylone induces developmental toxicity and dopaminergic receptor-regulated aberrances in zebrafish larvae.

N-Ethylpentylone (NEP) is one of the most recent novel stimulants, and there is limited understanding of its toxicity. Here we employed zebrafish model for analyzing the effects of NEP on early embryos and cardiovascular and nervous systems at late developmental stages. We first observed multi-malformations in early embryos and larvae after NEP administration, together with significant deregulations of brain and heart development-associated genes (neurog1, her6, elavl3, nkx2.

Manipulation of focal Wnt activity via synthetic cells in a double-humanized zebrafish model of tumorigenesis.

The canonical Wnt signaling pathway is activated in numerous contexts, including normal and cancerous tissues. Here, we describe a synthetic cell-based therapeutic strategy that inhibits aberrant Wnt activity in specific focuses without interfering with the normal tissues in vivo. As a proof of principle, we generated a triple transgenic zebrafish liver cancer model that conditionally expressed human MET and induced ectopic Wnt signaling in hepatocytes.

Combinatorial Normalization of Liver-Derived Cytokine Pathways Alleviates Hepatic Tumor-Associated Cachexia in Zebrafish.

The role and significance of liver-derived cytokines in cancer-associated cachexia syndrome remain elusive. Here we report that combinatorial counterbalances of the leptin and Igf1 signaling pathways in hepatocellular carcinoma (HCC) models significantly relieves cachexia. Double transgenic zebrafish models of HCC that stably displayed focal lesions, anorexia, and wasting of adipose and muscle tissues were first generated.
