Abstract

Lycopene, a potent antioxidant predominantly found in red-hued fruits and vegetables such as tomatoes, has been incorporated into embryonic maturation media in vitro, demonstrating enhancements in embryo quality. Despite these advancements, the specific effects of lycopene on Zebrafish embryo quality remain unexplored. This study aims to investigate the impact of lycopene (0.65 ppm) on the development of Zebrafish embryos, focusing on hatchability (HA), and heart rate (HR) under conditions of heat stress (HS). Fertile Zebrafish embryos at the gastrula stage were induced HS (30oC; 1 hour). The embryos will be segregated into two groups: those exposed to HS and nonHS (28oC). Each group will receive one of three treatments (four replicates): control / without lycopene (P1), 2μL lycopene (P2), and 4μL lycopene (P3). Observations using an inverted microscope was done every three up to 48 hours post-fertilization (hpf), and subsequently every five hours up to 96 hpf. Quantitative data obtained for HA and HR were analyzed with SPSS, One-Way ANNOVA (p<0.05). The antioxidants contained in lycopene can influence the speed and success of Zebrafish embryo development and HA exposed to HS. In addition, the antioxidant in lycopene can also suppress the HR frequency of Zebrafish embryos exposed to HS. However, more studies about the optimum dose, purity, and stability of the lycopene extract should be done to make a definitive conclusion.
Effects of Acetone Extract of Green Tea (Camellia sinensis) on Diameter, Viability, and Germinal Vesicle Breakdown Rate of Zebrafish Oocytes (Danio rerio) Exposed to Heat Stress as an Animal Model Tuska, Habib Syaiful Arif; Hidayah, Aaliyah Nurul; Lonameo, Bonick Kartini; Bello, Umar; Budiono

Abstract

Global warming is characterized by increasing temperatures of the earth's atmosphere, ocean and land, resulting in extreme climate change. The effects of climate change will affect animal health through increased ambient temperature (heat stress). This study using Zebrafish as animal model like our previuous study because Zebrafish, have 70% identical genetic similarity to humans. In addition, Zebrafish have specific approval from the U.S. Food and Drug Administration for new drug discovery research. Heat stress negatively affects animal health through an increase in Reactive Oxygen Species (ROS), especially in the reproductive system because it causes a decrease in reproductive efficiency, such as follicular development, oocyte quality, and oocyte maturation. Antioxidant supplementation, namely green tea extract, is needed to reduce the negative effects of heat stress. The purpose of this study was to analyze the difference of 4 µl dose of green tea extract (Camellia sinensis) on the diameter, viability, and Germinal Vesicle Breakdown (GVBD) rate of Zebrafish oocytes at normal temperature (28℃) and with exposure to heat stress (32℃; 34℃). Zebrafish oocytes were collected and grouped into 2 (two) treatment groups including, non-heat stress group (28℃) and heat stress group (32℃; 34℃) with 6 repetitions.  Quantitative data were processed using SPSS software with Two Way ANOVA analysis.  The results of Two Way ANOVA showed that green tea extract supplementation had a positive effect on the diameter, viability, and GVBD of Zebrafish oocytes. This is indicated by the significance of the percentage of diameter (P=0.002), viability (P=0.003), and GVBD rate (P=0.000).
