Description
To reveal distinct transcriptomes associated with spermatogonial stem cell renewal vs. initiation of differentiation, single-cell transcriptomes from Adult Human spermatogonia were subdivided into subpopulations based on the levels of ID4 mRNA (determined in this experiment). This correlates with distinct fates of corresponding mouse spermatogonia when assayed by transplantation, with ID4-EGFPbright cells highly enriched for SSCs, and ID4-EGFPdim cells enriched for progenitors. We used the Fluidigm C1 instrument to capture individual spermatogonia for SMART-Seq2 single-cell RNA-seq. Overall design: Nine replicate preparations of Adult Human spermatogonia were used for this study. Data are from a total of 635 cells. Cells were binned into quartiles according to ID4 mRNA levels (Q1 = ID4-high, Q4=ID4-low, Q2 and Q3 have intermediate ID4 mRNA levels) to facilitate comparisons.

Description
To reveal distinct transcriptomes associated with spermatogonial stem cell renewal vs. initiation of differentiation, single-cell transcriptomes from Adult ID4-EGFP+ spermatogonia were subdivided into subpopulations that displayed distinct fates when assayed by transplantation, with ID4-EGFPbright cells highly enriched for SSCs, and ID4-EGFPdim cells enriched for progenitors. We used the Fluidigm C1 instrument to capture individual spermatogonia for SMART-Seq2 single-cell RNA-seq. Overall design: Four replicate preparations of Adult mouse ID4-EGFP+ spermatogonia were used for this study. Data are from a total of 300 cells. Cells were binned into quartiles according to EGFP epifluorescence intensity (Q1 = EGFP-bright, Q4=EGFP-dim, Q2 and Q3 have intermediate EGFP fluorescence) to facilitate comparisons.

Description
To reveal distinct transcriptomes associated with spermatogonial stem cell renewal vs. initiation of differentiation, single-cell transcriptomes from P6 ID4-EGFP+ spermatogonia were subdivided into subpopulations that displayed distinct fates when assayed by transplantation, with ID4-EGFPbright cells highly enriched for SSCs, and ID4-EGFPdim cells enriched for progenitors. We used the Fluidigm C1 instrument to capture individual spermatogonia for SMART-Seq2 single-cell RNA-seq. Overall design: Five replicate preparations of mouse P6 ID4-EGFP+ spermatogonia were used for this study. Data are from a total of 278 cells. Cells were binned into quartiles according to EGFP epifluorescence intensity (Q1 = EGFP-bright, Q4=EGFP-dim, Q2 and Q3 have intermediate EGFP fluorescence) to facilitate comparisons.

Description
CD20 is a clinically validated target for Non-Hodgkins lymphomas and autoimmune diseases. Interactions of CD20 with the B cell receptor (BCR) and components of the BCR signaling cascade have been reported. In this study we show that antibodies against CD20 or activation of the BCR by specific antibodies induce very similar expression patterns of up- or down-regulated genes in NHL cell lines indicating that CD20 may play a role in BCR signaling and vice versa.

Description
Background: Several genetic defects of the nucleotide excision repair (NER) pathway, including deficiency of the Excision Repair Cross-Complementing rodent repair deficiency, complementation group 1 (ERCC1), result in pre-mature aging, impaired growth, microcephaly and delayed development of the cerebellum. Such a phenotype also occurs in ERCC1-knockout mice which survive for up to 4 weeks after birth. Therefore, we analyzed cerebellar and hippocamapal transcriptomes of these animals at 3 weeks of age to identify the candidate mechanisms underlying brain consequences of reduced ERCC1 activity.

Description
Retinoic acid (RA), an active derivative of the liposoluble vitamin A (retinol), acts as an important signaling molecule during embryonic development, regulating phenomenons as diverse as anterior-posterior axial patterning, forebrain and optic vesicle development, specification of hindbrain rhombomeres, pharyngeal arches and second heart field, somitogenesis, and differentiation of spinal cord neurons. This small molecule directly triggers gene activation by binding to nuclear receptors (RARs), switching them from potential repressors to transcriptional activators. The repertoire of RA-regulated genes in embryonic tissues is poorly characterized. We performed a comparative analysis of the transcriptomes of murine wild-type and Retinaldehyde Dehydrogenase 2 null-mutant (Raldh2-/-) embryos - unable to synthesize RA from maternally-derived retinol - using Affymetrix DNA microarrays. Transcriptomic changes were analyzed in two embryonic regions: anterior tissues including forebrain and optic vesicle, and posterior (trunk) tissues, at early stages preceding the appearance of overt phenotypic abnormalities. Several genes expected to be downregulated under RA deficiency appeared in the transcriptome data (e.g. Emx2, Foxg1 anteriorly, Cdx1, Hoxa1, Rarb posteriorly), whereas reverse-transcriptase-PCR and in situ hybridization performed for additional selected genes validated the changes identified through microarray analysis. Altogether, the affected genes belonged to numerous molecular pathways and cellular/organismal functions, demonstrating the pleiotropic nature of RA-dependent events. In both tissue samples, genes upregulated were more numerous than those downregulated, probably due to feedback regulatory loops. Bioinformatic clustering analysis allowed us to extract groups of genes displaying similar behaviors in mutant tissue samples. These data give an overview of the gene expression changes occurring under a state of embryonic RA deficiency, and provide new candidate genes and pathways for a better understanding of retinoid-dependent molecular events.

Description
Cells were grown to saturation in YPD (YEP + 2% glucose) for 24 hours, diluted into YPA (YEP + 2% potassium acetate) at OD600= 0.3 and grown over night at 30C. Cells were washed with sterilized water the next day and re-suspended in SPII medium (0.3% potassium acetate, pH = 7.0) at OD600= 1.9 to induce sporulation. Cells were sporulated at room temperature or 30C as indicated. Sporulation medium containing benomyl was always prepared freshly on the day of the experiment following the directions in {Shonn, 2000 #90}. Briefly, DMSO (dimethyl sulfoxide, Sigma-Aldrich) or benomyl [Methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate, Sigma-Aldrich; 30 mg/ml stock in DMSO] was dissolved in near-boiling SPII medium to avoid precipitation. The medium was then allowed to slowly cool to 30C or room temperature. At the time of drug treatment, cells were filtered and immediately re-suspended in the medium containing benomyl or DMSO.
