Description
The juvenile onset of spermatogenesis in mice is analyzed by combining cytological and transcriptomic data in a novel computational analysis, resulting in meiotic substage-specific transcriptomes and the discovery of a transcription factor network that regulates the substages of meiosis. Overall design: Germ cells from testes of individual mice were obtained at two-day intervals from 8 to 18 days post-partum (dpp), with five biological replicates at each age (samples 8_1 through 18_5). Eight stages were discriminated cytologically by combinatorial antibody labeling, and RNA-seq was performed on the same samples. A novel permutation-based maximum covariance analysis (PMCA) method was developed to deconvolve genes into meiotic substages. To verify PMCA derived pachytene/diplotene substage-specific genes, we isolated enriched populations of adult pachytene germ cells (samples rep1 through rep4), followed the same RNA-seq protocol, and compared the PMCA derived substage-specific gene lists to the genes expressed in the pachytene/diplotene enriched germ cells.

Description
Marf1 (MUT) female mice are infertile and the meiosis of the oocytes are arrest at prophase I. We thought to identify the potential causes of the meiotic arrest phenotype in the mutant oocytes by comparing the transcriptomes of the WT and mutant fully-grown oocytes (from 23-d old mice) that are transcriptional silent.

Description
Repro9 in an allele of Mybl1 (A-Myb) transcription factor obtained in ENU screen to identify alleles causing mouse infertility. Repro9/repro9 mutant males are infertile due to meiotic arrest at pachytene stage. Mutants show wide range of abnormalities including inefficient chromosome synapsis, sex body formation and progression through meiotic cycle. Females are unaffected. To determine genes transcriptionally regulated by MYBL1 we analyzed gene expression profiles of wild type and repro9/repro9 mutant testis at 14 and 17 days postpartum. Analysis revealed many misregulated genes, in majority downregulated, at day 14 pp and even more at day 17 pp, probably due to secondary effects of meiotic arrest. Significantly misregulated genes were characterized by Gene Ontology. Comparative gene expression analysis uncovered potential targets of MYBL1 regulation that play roles in regulation of transcription, cell cycle, apoptosis, protein phosphorylation and ubiquitination, chromosome organization and others.

Description
Human alveolar macrophages (HAM) are primary bacterial niche and immune response cells during Mycobacterium tuberculosis (M.tb) infection, and human blood monocyte-derived macrophages (MDM) are a model for investigating M.tb-macrophage interactions. Here, we use a targeted RNA-Seq method to measure transcriptome-wide changes in RNA expression patterns of freshly obtained HAM (used within 6 h) and 6 day cultured MDM upon M.tb infection over time (2, 24 and 72 h), in both uninfected and infected cells from three donors each. The Ion AmpliSeqâ„¢ Transcriptome Human Gene Expression Kit (AmpliSeq) uses primers targeting 18,574 mRNAs and 2,228 non-coding RNAs (ncRNAs) for a total of 20,802 transcripts. AmpliSeqTM yields highly precise and reproducible gene expression profiles (R2 >0.99). Taking advantage of AmpliSeq's reproducibility, we establish well-defined quantitative RNA expression patterns of HAM versus MDM, including significant M.tb-inducible genes, in networks and pathways that differ in part between MDM and HAM. A similar number of expressed genes are detected at all time-points between uninfected MDM and HAM, in common pathways including inflammatory and immune functions, but canonical pathway differences also exist. In particular, at 2 h, multiple genes relevant to the immune response are preferentially expressed in either uninfected HAM or MDM, while the HAM RNA profiles approximate MDM profiles over time in culture, highlighting the unique RNA expression profile of freshly obtained HAM. MDM demonstrate a greater transcriptional response than HAM upon M.tb infection, with 2 to >10 times more genes up- or down-regulated. The results identify key genes involved in cellular responses to M.tb in two different human macrophage types. Follow-up bioinformatics analysis indicates that approximately 30% of response genes have expression quantitative trait loci (eQTLs in GTEx), common DNA variants that can influence host gene expression susceptibility or resistance to M.tb, illustrated with the TREM1 gene cluster and IL-10. Overall design: Assessment of transcriptome profiles from cells infected with Mycobacterium tuberculosis using AmpliSeq.

Description
One of the long-standing goals in the field has been to establish a culture system that would allow maintenance of HSC properties ex vivo. In the absence of such system, the ability to model human hematopoiesis in vitro has been limited, and there has been little progress in the expansion of human HSCs for clinical application. To that end, we defined a mesenchyml stem cell co-culture system for expansion of clonally multipotent human HSPCs that are protected from apoptosis and immediate differentiation, and retain the HSPC phenotype. By performing a genome-wide gene expression analysis of purified HSPCs isolated at different stages of co-culture, we asked at the molecular level, to what degree hematopetic stem cell properties can be preserved during culture. This temporal gene expression data from in vivo derived- and ex vivo expanded human HSPCs will serve as a resource to identify novel regulatory pathways that control HSC properties, and to develop clinically applicable protocols for HSC expansion.
