Differences in the fatty-acid composition of rodent spermatozoa are associated to levels of sperm competition.

delBarco-Trillo J, Mateo R, Roldan ER - Biol Open (2015)

Bottom Line: To test these predictions, we quantified the fatty-acid composition of sperm, testis and liver cells in four mouse species (genus Mus) that differ in their levels of sperm competition.Fatty-acid composition in testis and liver cells was not associated to sperm competition levels.Two particular fatty acids were most responsible for this pattern (arachidonic acid and palmitic acid).

Representation of fatty-acid composition by tissue type and by species.Non-metric multidimensional scaling analysis of fatty-acid composition showing separation of samples by tissue type and partly separation by species within liver samples and sperm samples (n = 5 for each species, except n = 4 in the case of sperm data for M. spretus). Closer distances between any two samples reflect greater similarity in their fatty-acid composition.

Closer distances between any two samples reflect greater similarity in their fatty-acid composition.

Mentions: The non-metric multidimensional scaling (NMDS) analysis showed a separation of samples by tissue type, i.e. the fatty-acid composition was more similar within samples of one tissue type than between tissue types (Fig. 1). No clear separation by species was observed for testis samples. A separation by species was observed for liver samples, with a clear distinction between samples from M. pahari and samples from the other three species. Similarly, a clear separation was observed between sperm samples from M. pahari and M. musculus, whereas sperm samples from M. spretus and M. spicilegus were not clearly separated from each other.
