基于斑马鱼模型的鹿胶益气补血相关功效研究

Study on the Efficacy of Cervi Colla in Yiqi Buxue Based on the Zebrafish Model

目的通过斑马鱼模型快速观察鹿胶补血、健骨、抗衰老等补益作用。方法利用草甘膦(Gly)构建斑马鱼成鱼红细胞损伤模型,通过甲氨蝶呤(MTX)构建斑马鱼幼鱼造血功能损伤模型。通过泼尼松龙(Pred)构建斑马鱼幼鱼骨形成抑制模型。通过邻苯二甲酸二丁酯(DBP)构建斑马鱼幼鱼眼部细胞凋亡模型。结果鹿胶可改善Gly诱导的斑马鱼成鱼红细胞核异常,促进造血因子SCL、GATA1的表达;改善Pred诱导的斑马鱼幼鱼骨形成抑制,促进成骨相关ALP、Runx2a的表达;减少DBP引起的斑马鱼幼鱼眼部细胞凋亡数,促进抗凋亡因子Bcl-2的表达。结论鹿胶具有较好的保护红细胞、促进造血、促进骨形成、抗凋亡等作用,这些作用可能与其补血、抗骨质疏松、抗衰老等功效有关,该研究为鹿胶的临床应用提供科学依据,为进一步开发应用奠定基础。

Objective To quickly observe the tonic effects of Cervi Colla on enriching blood,strengthening bones and anti-aging in zebrafish model.Methods Glyphosate(Gly)was used to construct the erythrocyte injury model in adult zebrafish,and methotrexate(MTX)was used to construct the hematopoietic function injury model of juvenile zebrafish.Prednisolone(Pred)was used to establish the inhibition model of bone formation in zebrafish larvae.The ocular cell apoptosis model of zebrafish larvae was established by dibutyl phthalate(DBP).Results Cervi Colla could improve the Gly-induced abnormal erythrocyte nucleus in adult zebrafish and promote the expression of hematopoietic factors SCL and GATA1.Cervi Colla improved Pred-induced inhibition of bone formation in juvenile zebrafish,and promoted the expression of osteoblast-related gene ALP and Runx2a.The number of ocular cell apoptosis induced by DBP was decreased,and the expression of anti-apoptotic factor Bcl-2 was promoted.Conclusion Cervi Colla has significant effects on protecting erythrocyte,protecting hematopoiesis,protecting bone formation and anti-apoptosis.These effects may be related to replenish blood,anti-osteoporosis,and anti-aging.This study provides a scientific basis for the clinical application of Cervi Colla,and lays a foundation for further development and application.
