Distribution of H-FABP mRNA in Hybrids of Songliao Black Pig×Sus scrofa

[ Objective] This study was to investigate the distribution of H-FABP mRNA in hybrids of Songliao black pig x Sus scrofa, so as to provide references for revealing the physiological functions of this gene. [Method] With the mRNA from different tissues as template, RT-PCR amplification was carried out for cloning cDNA of hybrid pig, which was then used for PCR reaction using specific primers; the amplification products were separated by gel electrophoresis and analyzed by sequencing for detecting the distribution pattern of H-FABP mRNA in hybrids of Songliao black pig x Sus scrofa. [ Result] H-FABP expressed in all the twelve tissues including subcutaneous fat, abdominal fat, mammary gland, Iongissimus dorsi muscle, dorsal deltoid muscle, heart, liver, spleen, lung, kidney, ileum and duodenum. [ Conclusion] The wide distribution of H-FABP gene suggests that its functions are important and multiple.

松辽黑猪×野猪杂交猪H-FABP mRNA基因的组织分布研究

[目的]研究松辽黑猪×野猪杂交猪H-FABP mRNA基因的组织分布,为探明该基因的生理功能提供依据。[方法]采用RT-PCR技术获得松野杂交猪的cDNA,经PCR扩增后对目的片段进行电泳鉴定和测序,检测H-FABP mRNA在松辽黑猪×野猪杂交猪组织中的分布情况。[结果]在选取的皮下脂肪、腹脂、乳腺、背最长肌、臂三头肌、心脏、肝脏、脾脏、肺脏、肾脏、回肠、十二指肠共12种组织中,H-FABP mRNA均有表达。[结论]H-FABP基因在组织中广泛分布说明了其功能的重要性及多重性。
