Project description:To characterize the genetic basis of hybrid male sterility in detail, we used a systems genetics approach, integrating mapping of gene expression traits with sterility phenotypes and QTL. We measured genome-wide testis expression in 305 male F2s from a cross between wild-derived inbred strains of M. musculus musculus and M. m. domesticus. We identified several thousand cis- and trans-acting QTL contributing to expression variation (eQTL). Many trans eQTL cluster into eleven ‘hotspots,’ seven of which co-localize with QTL for sterility phenotypes identified in the cross. The number and clustering of trans eQTL - but not cis eQTL - were substantially lower when mapping was restricted to a ‘fertile’ subset of mice, providing evidence that trans eQTL hotspots are related to sterility. Functional annotation of transcripts with eQTL provides insights into the biological processes disrupted by sterility loci and guides prioritization of candidate genes. Using a conditional mapping approach, we identified eQTL dependent on interactions between loci, revealing a complex system of epistasis. Our results illuminate established patterns, including the role of the X chromosome in hybrid sterility.

Project description:We have identified GATA-3 as a critical regulator of luminal cell differentiation in the mammary gland. Acute loss of GATA-3 in the adult mammary gland leads to an expansion of an undifferentiated luminal epithelium and the formation of a multi-layered epithelium. Here we report microarray analysis of mammary glands that have undergone acute loss of GATA-3 Adult GATA-3flox/flox; WAP-rtTA-Cre and GATA-flox/+; WAP-rtTA-Cre mice were administered doxyxcline for 5 days and their mammary glands harvested. Total RNA was extracted by the Trizol method. Het mammary gland total RNA was labeled with Cy5 while Null mammary gland total RNA was labeled with Cy3. Microarray hybridization was performed on spotted oligonucleotide microarrays with 38,000 features. Lowess print-tip normalization and analysis was performed on the Acuity software package (V 4.0)

Our results illuminate established patterns, including the role of the X chromosome in hybrid sterility. Gene expression was measured in whole testis in males aged 70(M-BM-15) days. Samples include 294 WSB/EiJ x PWD/PhJ F2s, 11 PWD/PhJ x WSB/EiJ F2s, 8 WSB/EiJ, 8 PWD/PhJ, 6 PWD/PhJ x WSB/EiJ F1s and 4 WSB/EiJ x PWD/PhJ F1s.
