Description
Total RNA-sequencing on 150-200 ICOS+CD38+ cTfh cells per person prior to vaccination (day 0), and seven (day 63) and 28 (day 84) days after the third vaccination. Overall design: Blood samples were taken from healthy volunteers taking part in a Phase 1b clinical trial. mRNA was isolated from flow sorted circulating Tfh cells (CD4+CD45RA-CXCR5+PD1+ICOS+CD38+ cells) and RNA-sequencing performed on cTfh from days 0, 7 and 28 reletive to vaccination

Description
Total mRNA-sequencing on memory T helper cell populations from human blood and lymph nodes. Overall design: Paired blood and lymph node samples were taken from patients recruited from the renal transplant live donor program at Cambridge University Hospitals NHS Foundation Trust, and who provided informed consent. All patients were either receiving or within 6 months of requiring renal replacement therapy. Patients taking immunosuppressive medication prior to transplant were excluded. mRNA was isolated from flow sorted CD4+ T cell populations and RNA-sequencing performed.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The LEF/TCF family of transcription factors are downstream effectors of the WNT signaling pathway, which drives colon tumorigenesis. LEF/TCFs have a DNA sequence-specific HMG box that binds Wnt Response Elements (WREs). The E tail isoforms of TCFs are alternatively spliced to include a second DNA binding domain called the C-clamp. We show that induction of a dominant negative C-clamp version of TCF1 (dnTCF1E) induces a p21-dependent stall in the growth of DLD1 colon cancer cells. Induction of a C-clamp mutant did not induce p21 or stall cell growth. Microarray analysis revealed that induction of p21 by dnTCF1EWT correlated with a decrease in expression of p21 suppressors that act at multiple levels from transcription (SP5, YAP1, RUNX1), to RNA stability (MSI2), and protein stability (CUL4A). We show that the C-clamp is a sequence specific DNA binding domain that can make contacts with 5-RCCG-3 elements upstream or downstream of WREs. The C-clamp-RCCG interaction was critical for TCF1E mediated transcriptional control of p21-connected target gene promoters. Our results indicate that a WNT/p21 circuit is driven by C-clamp target gene selection.

Description
Autism is a common neurodevelopmental syndrome. Numerous rare genetic etiologies are reported; most cases are idiopathic. To uncover important gene dysregulation in autism we analyzed carefully selected idiopathic autistic and control cerebellar and BA19 (occipital) brain tissues using high resolution whole genome gene expression and DNA methylation microarrays. No changes in DNA methylation were identified in autistic brain but gene expression abnormalities in two areas of metabolism were apparent: down-regulation of genes of mitochondrial oxidative phosphorylation and of protein translation. We also found associations between specific behavioral domains of autism and specific brain gene expression modules related to myelin/myelination, inflammation/immune response and purinergic signaling. This work highlights two largely unrecognized molecular pathophysiological themes in autism and suggests differing molecular bases for autism behavioral endophenotypes.

Description
We hypothesized that preterm spontaneous labor involves aberrant changes in mRNA expression in the placenta. To test this hypothesis, we interrogated the mRNA levels of >50,000 genes and transcript variants using gene expression microarray (Human Genome U133 Plus 2.0 Array, Affymetrix) on 5 placentas collected from preterm spontaneous delivery (<34 weeks of gestation) and another 5 placentas collected from term spontaneous delivery (38-39 weeks).

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
This study examined the small antral follicles (SAFs) in ovaries of young adult rhesus monkeys following consumption of a western-style diet (WSD), with or without chronically elevated androgen levels since before puberty. Cholesterol or testosterone (T; n=6/group) implants were placed subcutaneously beginning at 1 yr of age, with addition of a WSD (high fat/fructose) at 5.5 yrs. Ovaries from treated females and age-matched controls were collected at 7 yrs of age. Compared to controls, consumption of a WSD, with and without T treatment, increased the numbers of SAFs per ovary (P<0.001), due to the presence of more atretic follicles (P<0.01). Immunostaining for the cellular proliferation markers (pRb and pH3) was greater in granulosa cells of healthy SAFs (P<0.01), while staining for the cell cycle inhibitor (p21) was higher in atretic SAFs (P<0.01). Intense CYP17A1 staining was observed on the theca of SAFs from WSD+/- T groups, compared to controls. Microarray analyses of the transcriptome in SAFs isolated from a subgroup (n=3/grp) of WSD and WSD+T treated females and controls consuming a standard diet, identified mRNA levels for 1944 genes changed >2-fold (p<0.05) among the three groups. Pathway analyses identified several gene pathways altered by WSD and/or WSD+T associated with lipid, carbohydrate and lipid metabolism, plus ovarian processes. Alterations of several SAF mRNAs are similar to those observed in follicular cells from women with PCOS. These data indicate chronic exposure to a WSD in the presence and absence of chronically elevated T alters structure and function of SAFs within primate ovaries.
