摘要：

Zebrafish is an emerging animal model for studies on auditory system. This model presents high comparability with humans, good accessibility to the hearing organ, and high throughput capacity. To better utilize this animal model, methodologies need to be used to quantify the hearing function of the zebrafish. Zebrafish displays a series of innate and robust behavior related to its auditory function. Here, we reviewed the advantage of using zebrafish in auditory research and then introduced three behavioral tests, as follows: the startle response, the vestibular-ocular reflex, and rheotaxis. These tests are discussed in terms of their physiological characteristics, up-to-date technical development, and apparatus description. Test limitation and areas to improve are also introduced. Finally, we revealed the feasibility of these applications in zebrafish behavioral assessment and their potential in the high-throughput screening on hearing-related genes and drugs.

Novel lysosome-targeted anticancer fluorescent agents used in zebrafish and nude mouse tumour imaging

《化学科学与工程前沿（英文）》 2022年第16卷第1期页码 112-120 doi: 10.1007/s11705-021-2075-5

摘要： The design of three novel fatty nitrogen mustard-based anticancer agents with fluorophores incorporated into the alkene structure (CXL 118, CXL121, and CXL122) is described in this report. The results indicated that these compounds are selectively located in lysosomes and exhibit effective antitumour activity. Notably, these compounds can directly serve as both reporting and imaging agents in vitro and in vivo without the need to add other fluorescent tagging agents.

Single and joint effects of HHCB and cadmium on zebrafish (

Lei ZHANG, Jing AN, Qixing ZHOU

《环境科学与工程前沿（英文）》 2012年第6卷第3期页码 360-372 doi: 10.1007/s11783-011-0353-z

摘要： As an important type of emerging pollutants, ecological toxicity and risk of artificial musks are increasingly concerned. Thus, single and joint toxic effects of 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8- hexamethylcyclopenta-gamma-2-benzopyran (HHCB) as one of the most widely applied artificial musks and cadmium (Cd) as an toxic metal on zebrafish ( ) were investigated by the exposure of zebrafish to various concentrations of HHCB or/and Cd in feculent water containing bedloads. The results indicated that the joint effect of HHCB and Cd changed during different exposure times within 120 h. The index of the antioxidant enzyme system including superoxide dismutase (SOD) and peroxidase (POD), and malondialdehyde (MDA) were sensitive and induced in the zebrafish stressed by Cd, and content of soluble protein (SP) was sensitive to HHCB and could be used as a biomarker for HHCB. Joint effects on antioxidant enzymes depended more on the effect of single Cd in the first one or two days. However, in the rest exposure days, the effect of HHCB began to dominate in the joint effect during the exposure process.

In vivo imaging of hematopoietic stem cell development in the zebrafish

摘要： imaging is crucial for developmental biology and can further help to follow cell development/differentiation in normal and pathological conditions. Recent advances in optical imaging techniques has facilitated tracing of the developmental dynamics of a specific organ, tissue, or even a single cell. The zebrafish is an excellent model for imaging of hematopoiesis due to its transparent embryo at early stage; moreover, different zebrafish hematopoietic stem cells (HSCs) transgenic lines have been demonstrated as very useful tools for illustrating the details of the HSC developmental process. In this review, we summarize recent studies related to the non-invasive imaging of HSC transgenics, to show that zebrafish transgenic lines are powerful tools for developmental biology and disease. At the end of the review, the perspective and some open questions in this field will be discussed.
