Project description:We have studied different subspecies of the house mouse (M. m. musculus, M. m. domesticus and M. m. castaneus) and their reciprocal F1 hybrids to estimate the within-locus mode of inheritance for subspecies differences in gene expression in three tissues (brain, liver, testis) of male mice. This study investigates mode of inheritance in crosses at a larger taxonomic distance than have been previously systematically investigated. We found the vast majority of transcripts to be additively expressed with only a few transcripts showing dominance or overdominance in expression, except for one direction of one cross, which showed large mis-expression in the testis. Experiment Overall Design: Wild-derived inbred lines of M. m. musculus, M. m. domesticus and M. m. castaneus were used to generate reciprocal crosses of M. m. musculus x M. m. domesticus and M. m. musculus x M. m. castaeneus. The gene expression profile of 2 males each of the hybrids and the pure parental subspecies were analyzed by using the Affymetrix GeneChip 430 2.0 to obtain evidence about the within-locus mode of inheritance of genes. First, we studied all transcripts that are differentially expressed between the parental subspecies and assessed additivity vs. nonadditivity of expression of these transcripts in the F1 hybrids. Second, we investigated those transcripts which do not differ in expression between the parental lines, but which are expressed differently in the F1 hybrids relative to both of their parents.

Project description:In eutherian mammals, dosage compensation of X-linked genes is achieved by X chromosome inactivation. X inactivation is random in embryonic and adult tissues, but imprinted X inactivation (paternal X silencing) has been identified in the extraembryonic membranes of the mouse, rat, and cow. Few other species have been studied for this trait, and the data from studies of the human placenta have been discordant or inconclusive. Here, we quantify X inactivation using RNA sequencing of placental tissue from reciprocal hybrids of horse and donkey (mule and hinny). In placental tissue from the equid hybrids and the horse parent the allelic expression pattern was consistent with random X inactivation, and imprinted X inactivation can clearly be excluded. We characterized horse and donkey XIST gene, and demonstrated that XIST allelic expression in female hybrid placental and fetal tissues is negatively correlated with the other X-linked genes chromosome-wide, which is consistent with the XIST-mediated mechanism of X inactivation discovered previously in mice. As the most structurally and morphologically diverse organ in mammals, the placenta also appears to show diverse mechanisms for dosage compensation that may result in differences in conceptus development across species. Examine allelic expression from individual samples of invasive trophoblast tissue of the chorionic girdle from gestation day 33-34 conceptuses of 5 horses, 3 donkeys, 6 mules, and 1 hinny.
