摘要: 【目的】研究HMGCS1基因对猪骨骼肌生长发育的影响及其靶标的验证。【方法】采用real-time PCR对通城猪不同组织以及背最长肌不同发育时间点的HMGCS1基因的表达变化进行检测。【结果】①HMGCS1基因在成年猪肺组织中的表达量最高;②在背最长肌发育中,该基因分别在胚胎期33 和65 d高表达,出生后20、30、40和60 d低表达;③双荧光素酶试验显示,转染miR-18a/b minics组荧光素酶活性低于对照组。【结论】HMGCS1参与了猪骨骼肌生长发育过程,并受miR-18a/b的调控,是猪的产肉性状的潜在候选基因。

Abstract: 【Objective】The purpose of the present research was to explore whether HMGCS1 impacts the skeletal muscle growth and development of pig and validate its target gene.【Method】In this study,the expression of HMGCS1 in different tissues and the expression change during Longissimus dorsi muscle development (28 stages) was investigated by real-time qPCR.【Result】The result showed that the HMGCS1 gene was strongly expressed in lung of adult pig, and the expression level of HMGCS1 gene in embryonic period 33 d and 65 d were higher than those in other periods in Tongcheng pigs, and lower expression at postnatal 20 d, 30 d, 40 d and 60 d. The luciferase activity was lower in miR-18a/b minics than in the control.【Conclusion】The results of study indicated that HMGCS1 regulates skeletal muscle growth and development by miR-18a/b, and is a potential candidate target gene of meat production traits.
