Description
The majority of babies in the US are formula-fed instead of breast fed. There are major differences in the composition of formulas and breast milk and yet little is known about metabolic differences in babies as the result of feeding these very different diets and how that might affect development or disease risk in later life. One concern is that soy-based formulas might have adverse health effects in babies as a result of the presence of low levels of estrogenic phytochemicals genistein and daidzein which are normally present in soy beans. In the current study, we used a piglet model to look at this question. Piglets were either fed breast milk from the sow or were fed two different infant formulas (cows milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food. Blood glucose and lipids were measured. Formula-fed pigs were found to have lower cholesterol than breast fed piglets and in addition had larger stores of iron in their liver.Microarray analysis was carried out to see if changes in liver gene expression could explain these effects of formula feeding. It was found that overall gene expression profiles were influenced by formula feeding compared to breast fed neonates. Gender-independent and unique effects of formula influenced cholesterol and iron metabolism. Further, soy formula feeding in comparison to milk-based formula failed to reveal any estrogenic actions on hepatic gene expression in either male or female pigs.

Illumina HiSeq 2000
Description
We conducted RNA-Seq (using Direct Ligation of Adapters to first strand cDNA) in neurons from E16.5 mouse embryonic cortices from WT and SMCX KO mice and harvested after 10 days in vitro culture. Overall design: We sequenced RNA samples after 10 days in vitro cultures in biological and technical duplicates. 4 RNA samples from WT and SMCX KO neurons. We also sequenced RNA samples from same neurons after stimulation with KCl for 60 mins. So a total of 8 RNA-Seq samples.

Description
We sequenced RNA from Pre-frontal cortex (PFC) and Amygdala from 3-6 month old adult mice. Overall design: The amygdala and the frontal cortex were dissected from three adult mice for each genotype (WT and SMCX KO) and homogenized in trizol. RNA was purified using Qiagen RNEasy kit and ribosomal RNA was depleted using Ribominus Eukaryote v2 kit from Life Technologies. RNA-Seq libraries were prepared using Direct Ligation of Adapters to first strand cDNA (DLAF) and subjected to 50 base sequencing on Illumina HiSeq2000.

Description
Background: Central nervous system (CNS) metastases represent a major problem in the treatment of HER2-positive breast cancer due to the disappointing efficacy of HER2-targeted therapies in the brain microenvironment. The antibody-drug conjugate ado-trastuzumab emtansine (T-DM1) has shown efficacy in trastuzumab-resistant systemic breast cancer. Here, we tested the hypothesis that T-DM1 could overcome trastuzumab resistance in preclinical models of brain metastases.

Description
Prostate organogenesis involves epithelial growth in response to inductive signalling from specialised subsets of mesenchyme. To identify regulators and morphogens active in mesenchyme, we performed transcriptomic analysis using Tag-seq, RNA-seq, and single cell RNA-seq and defined new mesenchymal subsets and markers. We documented transcript expression using Tag-seq and RNA-seq in female rat Ventral Mesenchymal Pad (VMP) as well as adjacent urethra comprised of smooth muscle and peri-urethral mesenchyme. Transcripts enriched in VMP were identified in Tag-seq data from microdissected tissue, and RNA-seq data derived from cell populations and single cells. We identified 400 transcripts as enriched or specific to the VMP using bio-informatic comparisons of Tag-seq and RNA-seq data. Comparison with single cell RNA-seq identified transcripts yielded 45 transcriptscommon to both approaches. Cell subset analysis showed that VMP and adjacent mesenchyme were composed of distinct cell types and that each tissue was comprised of two subgroups. Markers for these subgroups were highly subset specific. Thirteen transcripts were validated by qPCR to confirm cell specific expression in microdissected tissues, as well as expression in neonatal prostate. Immunohistochemical staining demonstrated that Ebf3 and Meis2 showed a restricted expression pattern in VMP condensed mesenchyme. Taken together, we demonstrate that the VMP shows limited cellular heterogeneity and that our high-resolution transcriptomic analysis identified new mesenchymal subset markers associated with prostate organogenesis. Overall design: Tag-sequencing, RNA-sequencing and single-cell RNA-sequencing on 2 female inductive mesenchymal tissues of the developing prostate/urogenital tract.

Description
We studied the synaptic activity-regulated gene expression response in the human genetic background using cultured human iPSC-derived (hiPSCd) neuronal networks and networks of hiPSCd neurons mixed with mouse primary neurons. Our results confirm that genetic changes affect the synaptic activity-regulated gene program, proposing a functional mechanism how they have driven evolution of human cognitive abilities. Overall design: We compared RNA profiles of untreated hiPSCd neurons and hiPSCd neurons treated with bicuculline and 4-aminopyridine for 1 or 4 hours. Samples were collected from hiPSCd neuron-only cultures and from co-cultures of hiPSCd neurons and mouse primary hippocampal neurons.
