Abstract
Responses of the PPARγ2 (an adipogenic lineage determinant) over-expressed immortalized bovine embryonic fibroblast cell line (BEFS-PPARγ2 cells) to trans-11 C18:1 (TVA) incubation were evaluated. BEFS-PPARγ2 cells were well differentiated. Stearoyl-CoA desaturase 1, an endoplasmic reticulum enzyme that can catalyze conversion of TVA into cis-9, trans-11 CLA, exhibited a significantly (p<0.05) higher mRNA expression after 4 h, compared with controls. Enzyme activity peaked, and was significantly (p<0.05) higher after 6 h, compared with controls. With extension of the incubation time, TVA absorption into cells was significantly (p<0.05) higher with significantly (p<0.05) more conversion into cis-9, trans-11 CLA, compared with shorter incubation times. TVA incubated cells exhibited significantly (p<0.05) higher levels of arachidonic, eicosapentaenoic, and docosahexaenoic acids than controls. BEFS-PPARγ2 cells can be used as a model system and TVA incubation is a good approach for research into cis-9, trans-11 CLA-fortified beef production.
