Proteomic comparison study between female and male tendon

Project description:Tendons play fundamental role in the musculoskeletal system and locomotion by transferring forces generated by muscles to the skeleton. Chronic tendon injuries and diseases are among the leading causes of musculoskeletal disability. For many types of tendinopathies, women have worse clinical outcomes than men. It is possible that tendon sex-based differences in protein composition are related to an altered injury response. The aim of this study was to compare the proteome of male and female tendon using label-free protein quantification. These data could provide new insight into pathways which may beinvolved in tendinopathies, and potentially in the differential injury response of female tendon.

Comparison of gene expression in male and female blastocysts

Project description:It is basically understood that male and female development is initiated by gonad differentiation into either testis or ovary. However, male embryos are reported to develop faster than female during preimplantation, implying sex differences at this stage. To learn more about when sex differentiation begins, we compared the global gene expression pattern of male and female embryos at the blastocyst stage. First, Blastocyst samples were sexed, using a novel method for non-invasive sexing of preimplantation stage mouse embryos by tagging the X chromosome with an EGFP transgene, Next, gene expression patterns of the male and female were compared using DNA microarray.

RNA-Seq of the different life history stages in Bostrychia moritziana (male gametophyte, female gametophyte, tetrasporophyte)

Project description:Diverse sex determination mechanisms have been reported in eukaryotes, but little is known about the genetic pathways leading to sex determination in red algae. Sex-specific genes that could be involved in sex determination and sexual differentiation were investigated in a red alga Bostrychia moritziana by analyzing the transcriptomes of various phases including males, females and tetrasporophytes. Sex-dominantly-expressed genes which shows >10 fold difference between sexes were isolated using comparative RNA-seq analysis. We found 19 gene homologues, 10 from males and 9 from females, that were found only in one sex in genomic amplification. This suggests that these divergent homologues are on non-recombining, possibly different, chromosomes in their respective sexes. Most of the sex-specific genes are involved in important cellular processes including chromosome segregation, nucleo-cytoplasmic protein shuttling or tRNA modification. Quantitative PCR analysis also showed that some sex-specific genes were differently regulated during critical events of sexual reproduction like fertilization and carposporophyte development. We could also localize the expression of a male-specific gene in spermatia before and after gamete binding using RNA in situ hybridization. Another set of transcripts were found that were sex-dominantly-expressed, but not sex-specific. 19 out of 39 sex-dominantly-expressed transcripts were annotated to transposable elements, but none of them was sex-specific. Our results suggest that sexual differentiation in B. moritziana may be achieved by multi-level regulation of cellular processes, both from genes present only in one sex and differential expression of shared genes.

Gene expression profiling of the olfactory tissues from sex-separated and sex-combined female and male mice

Project description:We sought to investigate the scope of cellular and molecular changes within a mouse’s olfactory system as a function of its exposure to odors emitted from members of the opposite sex. To this end, we housed mice either separated from members of the opposite sex (sex-separated) or together with members of the opposite sex (sex-combined) until six months of age and then profiled transcript levels within the main olfactory epithelium (MOE), vomeronasal organ (VNO), and olfactory bulb (OB) of the mice via RNA-seq. For each tissue type, we then analyzed gene expression differences between sex-separated males and sex-separated females (SM v SF), sex-combined males and sex-combined females (CM v CF), sex-separated females and sex-combined females (SF v CF), and sex-separated males and sex-combined males (SM v CM). Within both the MOE and VNO, we observed significantly more numerous gene expression differences between males and females when mice were sex-separated as compared to sex-combined. Chemoreceptors were highly enriched among the genes differentially expressed between males and females in sex-separated conditions, and these expression differences were found to reflect differences in the abundance of the corresponding sensory neurons.

Comparison of gene expression between male and female blastocysts

Project description:Male embryos are reported to develop faster than female in the preimplantation stage. Therefore, male and female embryos can be considered phenotypically different as early as the preimplantation stage. Employing our sexing system of enhanced green fluorescent protein (EGFP) tagging X chromosomes, we compared the global gene expression pattern of male and female embryos at the blastocyst stage using DNA microarray.

Title Multi-generational mRNA sequence data of pooled Drosophila melanogaster male and female flies from populations selected for long or short night sleep

Project description:Our objective was to determine whether gene expression in Drosophila melanogaster selectively bred for long or short night sleep duration changes detectably across generations. To meet this objective, we performed transcriptional profiling of ten pooled whole adult individuals from four selected populations and two control populations across 13 generations. We quantified differential expression among selection scheme (long sleep, short sleep, or unselected control), generation (generation 0; then generations 2-13), and sex for each gene.

Comparison of male and female floral organs

Project description:We conducted micro-array analysis to quantify the global transcriptome variations in floral organs of a male and female tree allowing for identification of sex-linked transcripts. We used RNA samples from male floral buds in August and female floral buds in September. Bud scale were removed. While the sampling time differed, the developmental stage of the floral organs was similar between the male and female. Five independent samples of floral bud tissues with bud scales removes were collected from the upper crown of a sexually mature male tree and female tree. RNA was extracted from tissues and hybridized on Affymetrix Genechip Poplar Genome Array.
