Adipose tissue triacylglycerols are the quantitatively most important source of stored energy in animals. Hormone-sensitive lipase encoded by hormone-sensitive lipase gene (Hsl) is a multifunctional enzyme that catalyzes the hydrolysis of triacylglycerol stored in adipose tissue and cholesterol esters in the adrenals, ovaries, testes and macrophages. Using pig Hsl gene inserted into pBS labeled by the radioactive isotope and the digoxigenin as the probes respectively one band, 11.5kb, has been shown to hybridized with total DNA of rice field eel digested with Pst I by Southern blotting and Hsl gene has been assigned to metaphase chromosome 5, at the position of 78.35+/-1.26 from the centromere in rice field eel by fluorescent in situ hybridization (FISH). The mapping results are corresponding to that of "specific-chromosomal DNA pool" obtained by chromosome microisolation used to map gene and the mapping result is more accurate. The results of the study further illustrate the importance of the presence of Hsl gene in rice field eel genome and provide the first FISH mapping data for rice field eel chromosome 5. The current studies would advance the addition of known genetic markers and the construction of high resolution genetic map in rice field eel genome. |
