Expression data from the reproductive tracts of WT, Hoxa9,10,11, and Hoxd9,10,11 mutant mice

ABSTRACT: Hox genes are key regulators of development. In mammals, the study of these genes is greatly confounded by their large number, overlapping functions, and their interspersed shared enhancers. In this report, we describe a novel recombineering strategy that was used to introduce simultaneous frameshift mutations into the flanking Hoxa9, Hoxa10, and Hoxa11 genes, as well as their paralogs on the HoxD cluster. The resulting mutant mice displayed dramatic homeotic transformations of the reproductive tracts, with uterus anteriorized towards oviduct and the vas deferens anteriorized towards epididymis. The Hoxa9,10,11 mutant mice provided a sensitized genetic background that allowed the discovery of Hoxd9,10,11 reproductive tract patterning function. Both shared and distinct Hox functions were defined. The HoxD genes played a crucial role in the regulation of the uterine immune function. Non-coding nonpolyadenylated RNAs were among the key Hox targets. In addition, we observed a surprising anti-dogmatic posteriorization of the uterine epithelium.

Reproductive tracts were collected from WT and Hox mutant mice (n=3/genotype) aged 3-7 months in order to characterize the molecular changes caused by mutation of Hoxa9,10,11 and Hoxd9,10,11. Female mice were staged and collected in diestrus.

Hox Abdominal-B Genes in the Developing Kidney

Project description:The Hox complex consists of 39 genes arranged in 4 clusters of flanking genes and 13 paralogous groups in mammals. To assess the functional redundancy of Hox abdominal-B genes during renal development, we used a modified recombineering strategy to simultaneous introduce frameshift mutations into the Hox9, Hox10, and Hox11 flanking genes of the HoxA, HoxC, and HoxD paralogous groups. We performed RNA seq on whole kidneys at E18.5 in triplicates for representative genotypes including: wild type; Hoxa9,10,11-/- HoxC9,10,11+/-, Hoxa9,10,11+/- HoxC9,10,11-/-, Hoxa9,10,11-/- HoxC9,10,11-/-. Our results suggest that the loss of Hox function results in a partial metanephric to mesonephric transformation, with tubules co-expressing markers of both proximal tubules and collecting ducts, as well as markers of mesonephric-derived epididymis tubules.

Anatomical transcriptome atlas of the male mouse reproductive system during aging

Project description:The testis, efferent ductules, epididymis, and vas deferens, constituting the majority of male reproductive tract, are the regions for testosterone production, spermatogenesis, and sperm maturation, storage and discharge, but whether these regions change during aging is unknown. Here, we addressed this by investigating the adult (3-month) and aged (18-month) transcriptomes from seven regions of male mouse reproductive tract：the testis, efferent ductules, initial segment, caput, corpus and cauda epididymis, and vas deferens. We identified various of region-specific genes across different regions of male mouse reproductive tract. Moreover, we identified region-dependent changes of transcripts at an anatomic resolution. This study provides a framework for futher studies on male reproducitve aging.

Gene expression in the Efferent duct, Epididymis, and Vas deferens during Embryonic Development

Project description:The tissues of the male reproductive tract are characterized by distinct morphologies, ranging from highly coiled to un-coiled. Global gene expression profiles of the efferent ducts, epididymis, and vas deferens were generated from embryonic day 14.5 to postnatal day 1, the period when gross morphological changes are initiated and tissue-specific morphologies emerge. Expression profiles of homeobox genes, as potential regionalization factors, were examined. Tissue transcriptome comparison identified two expression profiles of interest: genes similar between the epididymis and vas deferens early in development but dissimilar later and genes dissimilar between the epididymis and efferent duct early but similar later. Ontology analysis demonstrated cell adhesion-associated genes to be highly enriched in both comparisons. This work identified several potential regulators of cell adhesion along the tract and indicates cell adhesion may be modulated in a tissue-specific manner, playing an important role in the establishment of each tissueâs final morphology.

Transcriptomic analysis of polychaete-enhanced testicular maturation in male broodstock of the black tiger shrimp (Penaeus monodon)

Project description:The study aimed to determine effect of polychaetes as a shrimp feed on male reproductive maturation at transcriptional level through a cDNA microarray in the black tiger shrimp (Penaeus monodon). Thus, the experiment was to compare transcriptomic profiles of two different parts of reproductive organs, namely testes (TT) and vas deferens (VD), of domesticated 17-month-old between two different feeds, namely commercial pellet and polychaetes after feeding for one month. Differentially expressed genes were identified through the microarray analysis, and the microarray results were confirmed by real-time PCR. Selected genes were further characterized.

Cytosine methylation dynamics during spermatogenesis and post-testicular sperm maturation

Project description:We carried out whole genome bisulfite sequencing in seven purified sperm populations, including primary spermatocytes, early and late round spermatids, and mature sperm isolated from the caput, corpus, and cauda epididiymis, and from the vas deferens.

Laser capture microdissection/RNA-Seq analyses of Hoxa9,10,11/Hoxd9,10,11 mutant limb development

Project description:We used a novel recombineering method to introduce frameshift mutations into the first exons of the flanking Hoxa9,10,11 and Hoxd9,10,11 genes. By interbreeding it was possibleto make mice homozygous mutant for all six genes. These mice showed an extreme shortening of the zeugopod, with only tiny cartilaginous remnants of the ulna and radius made.We used laser capture microdissection to isolate the cells of the developing mutant zeugopods. Mutant and wild type samples were compared by RNA-seq. The results define the many downstream functional pathways perturbed by the Hox mutations, including the upregulation of many genes known to inhibit chondrocyte and osteoblast differentiation, BMP signalin, and growth arrest and apoptosis. In addition we observed the downregulation of genes required for WNT signaling and chonrdocyte maturation.
