Dimethylsulfoxide and conjugated linoleic acids affect bovine embryo development in vitro


Stinshoff, H; Wilkening, S; Hanstedt, A; Bollwein, H; Wrenzycki, C (2013). Dimethylsulfoxide and conjugated linoleic acids affect bovine embryo development in vitro. Reproduction, Fertility and Development, 59(3):296-301.

Abstract

Conjugated linoleic acids (CLA) are employed to overcome the bovine periparturitional negative energy balance. Especially of interest are trans10,cis12 -linoleic acid (t10c12-CLA) and cis9,trans11-linoleic acid (c9t11-CLA). Their impact on embryonic development, though, is not clear. Here, effects of both above-mentioned CLA on bovine in vitro-produced embryos were assessed. Zygotes (n = 2098) were allocated to one of seven groups: cultured with 50 or 100 µM of either c9t11-CLA or t10c12-CLA, with 14 or 28 mM DMSO or without supplement (control). Messenger RNA analysis of target gene transcripts (IGF1R, IGFBP2, IGFBP4, CPT2, ACAA1, ACAA2, FASN, SCD) via RT-qPCR was performed in single blastocysts. Cleavage rates did not differ, whereas development rates were decreased in both t10c12-supplemented groups in comparison to the unsupplemented group (31.7% ± 2.2 control vs 20.2% ± 2.0 50 µM t10c12 vs 21.0% ± 2.8 100 µM t10c12). Compared with the unsupplemented group, SCD was expressed at a lower level in embryos cultured with 50 µM c9t11-CLA. The relative amount of several transcripts was increased in embryos cultured with 14 mM DMSO in comparison to those that developed in the presence of 50 µM t10c12-CLA (IGFBP2, ACAA1, CPT2, FASN, SCD) or 50 µM c9t11-CLA (IGF1R, IGFBP2, ACAA1, CPT2, FASN, SCD). The molecular analyses show that CLA influence embryonic fat metabolism.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
