Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We compared splenic Va14i NKT cells from C57BL/6 control mice and from mice injected 4 weeks earlier intravenously with 4ug/mouse of the iNKT cell antigen alpha-galactosylceramide (aGalCer). These mice were either left unstimulated or were stimulated with 1ug/mouse aGalCer i.v.. All mice were female and 8 weeks of age at the beginning of the experiment. Va14i NKT cells were enriched via magnetic selection and cell sorted for TCRb+ CD1d/aGalCer-tetramer+. Total RNA were prepared using a Qiagen RNeasy mini kit. IVT probe generation and hybridization to Affymetrix Mouse Genome 430 2.0 arrays was carried out by the Veterans Medical Research Foundation GeneChipTM Microarray located at UCSD.

Description
The development of the epidermis, a stratified squamous epithelium, is dependent on the regulated differentiation of keratinocytes. Differentiation begins with the initiation of stratification, a process tightly controlled through proper gene expression. AP-2 is expressed in skin and previous research suggested a pathway where p63 gene induction results in increased expression of AP-2 which in turn is responsible for induction of K14. This study uses a conditional gene ablation model to further explore the role of AP-2 in skin development. Mice deficient for AP-2 exhibited delayed expression of p63, K14, and K1, key genes required for development and differentiation of the epidermis. In addition, microarray analysis of E16.5 skin revealed delayed expression of additional late epidermal differentiation genes: filaggrin, repetin and secreted Ly6/Plaur domain containing 1, in mutant mice. The genetic delay in skin development was further confirmed by a functional delay in the formation of an epidermal barrier. These results document an important role for AP-2 in skin development, and reveal the existence of regulatory factors that can compensate for AP-2 in its absence.

Description
In humans, the most common sex chromosomal disorder is Klinefelter syndrome (KS), caused by the presence of one or more extra X-chromosomes. The KS patients display a diverse adult phenotype with increased height, gynaecomastia, and hypergonadotropic hypogonadism as the most common symptoms. Men with KS are almost always infertile due to testicular degeneration, which accelerates during puberty. Very few studies investigated when the germ cell loss begins and whether it is caused by dysgenetic fetal development of the testes. We investigated a series of fetal KS testis tissue samples and found a marked reduction in MAGE-A4-positive pre-spermatogonia in the developing KS gonads compared to controls, indicating a failure of the gonocytes to differentiate into pre-spermatogonia. Transcriptome analysis by RNA sequencing of formalin-fixed and paraffin embedded gonads originating from 4 fetal KS samples and 5 age- and cellularity-matched controls revealed 211 differentially expressed transcripts in the fetal KS testis. We found a significant enrichment of upregulated X-chromosomal transcripts and validated the expression of the pseudoautosomal region 1 (PAR1) gene, AKAP17A. Moreover, we found enrichment of long non-coding RNAs in the KS testes (e.g. LINC01569 and RP11-485F13.1). In conclusion, our data indicates that the testicular phenotype observed among adult men with KS is initiated already in fetal life by failure of the gonocyte differentiation into pre-spermatogonia, which could be due to aberrant expression of long non-coding RNAs. Overall design: Includes a total of 9 samples. 4 fetal Klinefelter and 5 age-matched controls testis samples

The samples include RNA from scalp biopsies before treatment and at 8 weeks of treatment with Tofacitinib Citrate 5 mg BID in patients with Alopecia Areata. 32% had a SALT score of 50% or higher and 47% had clinically significant response. Overall design: Open label trial of patients with Alopecia Areata of more than 6 months in duration refractory to standard therapy. Each patient took tofacitinib citrate 5mg BID for 3 months and then stopped. Biopsies were taken pretreatment and then at 8 weeks from the scalp and submitted for RNA sequencing.

In humans, the most common sex chromosomal disorder is Klinefelter syndrome (KS), caused by the presence of one or more extra X-chromosomes. The KS patients display a diverse adult phenotype with increased height, gynaecomastia, and hypergonadotropic hypogonadism as the most common symptoms. Men with KS are almost always infertile due to testicular degeneration, which accelerates during puberty. Very few studies investigated the global gene expression analysis of adult KS testes and, more importantly, which cell types the differentially expressed transcripts originate from. Transcriptome analysis by RNA sequencing of fixed and paraffin embedded testes originating from 3 adult KS samples and 3 adult cellularity-matched controls revealed 236 differentially expressed transcripts in the adult KS testis. To examine the cellular origin of the differentially expressed transcripts, transcriptome profiling was also carried out on 4 testes with Sertoli Cell-Only and 4 testes with full spermatogenesis. Also, pre-pubertal KS and controls were RNA-sequenced. Overall design: Includes a total of 22 testis samples. 3 adult Klinefelter, 3 Klinefelter-like, 4 Sertoli Cell-Only, 4 with full spermatogenesi, 4 pre-pubertal Klinefelter and 4 pre-pubertal controls

Description
To uncover the gene expression alterations that occur during lung cancer progression, we interrogated the gene expression state of neoplastic cells at different stages of malignant progression. We initiated tumors in KrasLSL-G12D/+;p53flox/flox;R26LSL-tdTomato (KPT) mice with a pool of barcoded lentiviral-Cre vectors and purified Tomatopositive cancer cells away from the diverse and variable stromal cell populations. Five to nine months after tumor initiation, cancer cells were isolated from individual primary tumors and metastases using fluorescence-activated cell sorting. Sequencing of the barcode region of the integrated lentiviral vectors established primary tumor-metastasis and metastasis-metastasis relationships. Tumor barcoding allowed us to unequivocally distinguish non-metastatic primary tumors (TnonMet) from those primary tumors that had seeded metastases (TMet). We profiled 10 TnonMet samples as well as TMet and metastasis (Met) samples representing 12 metastatic events. To examine additional earlier stages of lung cancer development, we also analyzed premalignant cells from hyperplasias that develop in KPT mice shortly after tumor initiation (KPT-Early; KPT-E), as well as tumors from KrasG12D;R26LSL-tdTomato (KT) mice which rarely gain metastatic ability Overall design: This study includes 52 samples: 3 KP late samples, 3KPT early samples,10 non-metastatic primary tumors, 9 metastatic primary tumors, and 27 metastasis in different organs. total RNA was isolated and prepared for sequencing using the Ovation® RNA-Seq system and Illumina TruSeq DNA kit (v2) to generate 100bp paired end reads. Reads were aligned to mm10.
