Project description:There is a lack of systematic investigations of large-scale transcriptome patterns associated with normal breast development. Herein, we profiled whole-transcriptome (by microarrays) of normal mammary glands in female Sprague-Dawley rats, an animal model widely used in breast cancer research, across six distinctive developmental stages – pre-pubertal, peri-pubertal, pubertal, lactation, and adult parous and age-matched nulliparous.

Project description:MicroRNAs (miRNAs) are small noncoding RNAs that participate in regulation of gene expression. Their role during mammary gland development is still largely unknown. In the present study, we performed a microarray analysis to identify miRNAs associated with high mammogenic potential of bovine mammary gland. We identified 54 miRNAs differing significantly between mammary tissue of dairy (Holstein-Friesian, HF) and beef (Limousine, LM) post-pubertal heifers. Fifty two miRNAs had higher expression in the mammary tissue of LM heifers. Enrichment analyses for targeted genes revealed that the major differences between miRNA expression in the mammary gland of HF vs. LM were associated with regulation of signalling pathways crucial for mammary gland development, such as: TGF-beta, insulin, WNT and inflammatory pathways. Moreover, a number of genes potentially targeted by differentially expressed miRNAs was associated with mammary stem cells’ activity. These data indicate that in dairy cattle high developmental potential of the mammary gland, leading to high milk productivity, not only depends on central neuro-endocrine regulation but also on specific miRNA expression pattern. miRNA profiling of Holstein Freisian (dairy breed) and Limousne heifers (beef breed) mammay glands. Two-condition experiment, LM (test) vs. HF (reference). Total RNA was isolated from quarters of 4 LM and 4 HFmammary glands.

Project description:Puberty is a complex physiological event measured by various indicator traits in genetic improvement programs of beef cattle; thus, developing a more complete understanding of the genes and regulatory pathways and networks involved in puberty will provide knowledge to help improve genetic selection strategies. Herein, we characterized the transcriptome of five reproductive tissues (i.e. hypothalamus, pituitary gland, ovary, uterus, and endometrium) as well as tissues known to be relevant to growth and metabolism needed for cattle to achieve puberty (i.e., longissimus dorsi muscle, fat, and liver). These tissues were collected from pre (PRE)- and post (POST)-pubertal Brangus (3/8 Brahman; Bos indicus x 5/8 Angus; Bos taurus) heifers derived from a population of cattle used to identify QTL associated with fertility traits. In order to exploit the power of complementary omics analyses, PRE and POST puberty co-expression gene networks were constructed by combining the results from RNA-Seq, GWAS, and bovine transcription factors. RNA-Seq of 8 tissues among PRE and POST Brangus heifers revealed 1515 differentiallyexpressed and 943 tissue-specific genes within the 17,832 genes confirmed by metrics of RNA-Seq analysis. Combining the results from RNA-Seq and GWAS indentified a total of 25 QTL associated to heifer fertility. The hypothalamus experienced the most notable up-regulation of genes via puberty. Complementary omics procedures revealed 2,450 co-expressed genes across the 8 tissues relative to puberty. The PRE network had 372,861 connections whereas the POST network had 328,357 connections. A sub-network from this process revealed key transcriptional regulators (i.e., PITX2, FOXA1, TSG1D1, DACH2, LHX4, PROP1 and SIX6). Results from multiples sources of omics data will facilitate the design of breeding strategies to improve fertility in Bos indicus-influenced composite cattle. Sixty-one samples from PRE and POST pubertal composite beef heifers were analyzed with RNA-Seq. The transcriptome of five reproductive tissues (i.e. hypothalamus, pituitary gland, ovary, uterus, and endometrium) as well as tissues known to be relevant to metabolism andbody morphometrics needed for cattle to achieve puberty (i.e.,) was characterized. These tissues were collected from pre (PRE)- and post (POST)-pubertal Brangus (3/8 Brahman x 5/8 Angus) heifers derived from a population of cattle used to identify QTL associated with fertility. Total RNA was purified using a Trizol protocol (Invitrogen, Carlsbad, CA). Sequencing libraries were made using TruSeq RNA Sample Preparation kit of Illumina (San Diego, CA).

Project description:Wagyu cattle are renowned for their premium beef characterized by abundant intramuscular fat (IMF). In contrast, Brahman, a popular breed in the southern coastal area of the US, generally produces tough meat with scarce IMF. However, the mechanisms underlying the differential meat quality between the two breeds are still largely unknown. Using single-cell RNAseq (scRNAseq), we identified many tissue-resident and immune cell types in Wagyu, Brahman, and Wagyu/Brahman crossbred cattle muscle. Multiple fibro/adipogenic progenitor (FAP) subpopulations were identified, including an endomysial adipogenic subpopulation and a perimysial fibrogenic subpopulation. Further analysis comparing individual FAP subpopulations between Wagyu and Brahman identified stronger pro-adipogenic gene expression in Wagyu adipogenic FAP subpopulation and higher pro-fibrogenic gene expression in Brahman fibrogenic FAP subpopulation. Overexpression of CFD, a gene upregulated in Wagyu adipogenic FAPs, enhanced the adipogenic efficiency of FAPs. Moreover, the expression of CFD in FAPs was positively correlated with the IMF content. Interestingly, the expression of CFD was identified in human FAPs but not FAPs of mouse models of intramuscular adipogenesis, suggesting that CFD is a species-specific regulator of IMF formation. Using a mouse line that allows lineage-tracing of FAPs expressing Postn, a gene upregulated in Brahman FAPs, we found that Postn expression was specifically activated during fibrogenic but not adipogenic programming. Cell-cell communication analysis revealed robust interactions between FAPs and other cell types, further suggesting the critical role of FAPs in bovine skeletal muscle growth, development, and homeostasis.

Project description:Androgen-signaling is essential for prostate development. However, how androgen action facilitates prostatic stem/progenitor initiated pubertal prostatic growth remains unclear. Here, we demonstrate that androgens regulate Shh-signaling to control the cellular niche in prostatic epithelial development. Selective deletion of androgen receptor (AR) in stromal Shh-responsive cells significantly impedes pubertal prostatic epithelial morphogenesis and growth. Dysregulation of developmental signaling networks revealed in both prostatic stromal and epithelial cells of AR-deficient mice. Specifically, deletion of AR yielded increased Gli1 expression in prostatic stromal cells, elevated Shh expression in adjacent epithelial cells and stark inhibition of prostate cell growth. Trajectory analysis revealed AR deletion induces abnormal differentiation patterns of prostatic epithelia. Recombination of prostatic epithelial cells with AR-deficient stromal Gli1-expressing cells fails to develop normal prostatic epithelia. These data demonstrate the decisive role of stromal AR in interacting with Shh-signaling in the cellular niche to control pubertal prostatic morphogenesis and growth.
