Transgenic Bovine Nuclear Transfer Embryos From Adult Somatic Cell Lines*, Sezen Arat, S. Jacek Rzucidlo, Steven L. Stice Jan 2003

Transgenic Bovine Nuclear Transfer Embryos From Adult Somatic Cell Lines*, Sezen Arat, S. Jacek Rzucidlo, Steven L. Stice

Turkish Journal of Veterinary & Animal Sciences

This study was performed to examine whether adult fibroblast cells can be manipulated genetically and whether clonal lines derived from those cells can support embryonic development. A primary adult cell line was established from the ear of an aged cow. Adult cells with a plasmid containing the enhancer green fluorescence protein (EGFP) gene, and non-transfected cells were used for cloning. Green fluorescence expression was observed in 35/49 (71.4%) adult clones. The developmental rates of embryos were significantly lower for cell lines expressing EGFP (11.4%) than for non-transfected cells (20.1%, P < 0.05). However, there was no decrease in nuclear transfer (NT) developmental rates (21.5%) when donor nuclei from EGFP transfected cell lines not expressing EGFP but retaining neomycin-resistance gene expression were used as donor nuclei. The NT embryos from transfected and non-transfected cell lines had similar morphology and cell numbers. The results indicated that adult cells can complete clonal propagation including transfection and selection and can be used to produce transgenic NT embryos.

Turkish Journal of Veterinary & Animal Sciences

The possible pharmacological and toxicological effects of Pistacia terebinthus L. in experimentally hypercholesterolemic rabbits were investigated in this study. A total of 28 rabbits were divided into four groups, and these groups were fed diets containing standard pellets (Group 1), cholesterol (2%) (Group II), P. terebinthus L. (1 g/kg body weight) and cholesterol (2%) (Group III) and P. terebinthus L. (1 g/kg body weight) (Group IV) for 14 weeks. When the data were statistically evaluated over the weeks, body weight gains, showed no marked difference among the groups although liver weight was 58% higher in the cholesterol control group (P < 0.01) and 20.3% higher in P. terebinthus L. and cholesterol group than in the control group. In the comparison of the cholesterol-fed groups, Group III exhibited a marked decrease (P < 0.01) in total cholesterol and triglyceride evels and very low density lipoprotein (VLDL) and low density lipoprotein (LDL) levels by the 14th week and a 1.3-times higher (P < 0.001) high density lipoprotein (HDL) value. In the group fed cholesterol and P. terebinthus L., clotting and bleeding times increased by 13% and 12%, respectively, compored to the cholesterol control group. On account of the histopathological findings, it was confirmed that P. terebinthus L. restrained the progression of the atherosclerotic lesions in the thoracic artery and of hydropic degeneration and fatty changes in the liver. No toxic effect could be attributed to P. terebinthus L. from an investigation of the biochemical data. The results of this study show that P. terebinthus L. has a hypolipidemic effect in hypercholesterolemic rabbits.
