Hypoxia during pregnancy generates oxidative stress that alters the growth and development of the human fetus. Insulin-like growth factor-I (IGF-1) receptors are essential for normal fetal growth. Asiatic acid in Centella asiatica (CA) has antioxidant properties to prevent growth impairment in hypoxia.
This study aimed to investigate the effect of asiatic acid on the morphological development of an intermittent hypoxia zebrafish embryo model and analyse molecular docking prediction in insulin-like growth factor-1 receptor (IGF-1R) signalling.
Embryos of zebrafish at 2 hours postfertilization (hpf) were assigned to control negative (C), intermittent hypoxia (IH), and combination IH and CA extract groups consisting of 1.25 (IHCA1), 2.5 (IHCA2), and 5 (IHCA3) µg/ml. Hypoxia treatment (conducted 4 hours/day) and CA extract were administered for 3 days (2 - 72 hpf). The parameters of body length and head length were evaluated at 3, 6, and 9 days postfertilization (dpf). The data were analysed by a two-way ANOVA (P
