Description
In order to find a relationship between gene expression of blood and brain in Rett Syndrome (RTT), we performed RNA sequencing on from cerebella and blood of 7 week-old male Mecp2-null mice (a model of RTT) and WT controls. Overall design: Transcriptional profiles were generated from cerebellum and blood of 3 Mecp2-null and 3 WT 7 week-old male mice, by RNAseq performed on an Illumina HiSeq 2000 System, generating approximately 60 million 2x75bp paired-end reads/sample. Blood and cerebellum samples originate from the same animal

Description
Zinc (Zn2+) is an integral component of many proteins and has been shown to act in a regulatory capacity in different mammalian systems, including as a neurotransmitter in neurons throughout the brain. While Zn2+ plays an important role in modulating neuronal potentiation and synaptic plasticity, little is known about the signaling mechanisms of this regulation. In dissociated rat hippocampal neuron cultures, we used fluorescent Zn2+ sensors to rigorously define resting Zn2+ levels and stimulation-dependent intracellular Zn2+ dynamics, and we performed RNA-Seq to characterize Zn2+-dependent transcriptional effects upon stimulation. We found that relatively small changes in cytosolic Zn2+ during stimulation altered expression levels of 931 genes, and these Zn2+ dynamics induced transcription of many genes implicated in neurite expansion and synaptic growth. Additionally, while we were unable to verify the presence of synaptic Zn2+ in these cultures, we did detect the synaptic vesicle Zn2+ transporter ZnT3 and found it to be substantially upregulated by cytosolic Zn2+ increases. These results provide the first global sequencing-based examination of Zn2+-dependent changes in transcription and identify genes that may mediate Zn2+-dependent processes and functions. Overall design: 3 replicates of each of 3 conditions (KCl treatment, KCl/Zn treatment, KCl/TPA treatment), none of which are control conditions. KCl treatment was used as the reference condition for all comparisons. TPA = tris(2-pyridylmethyl)amine, a Zn2+ chelator.

Description
In this study, we analyzed how non-coding double stranded RNA (dsRNAs) act as a damage associated molecular pattern (DAMP) in the skin, and how the human cathelicidin AMP LL-37 might influence growth factor production in response to this DAMP. Overall design: Each sample''s RNA was isolated form a single biological source of P6 NHEKs. In total there are 4 samples (non-replicates); Control (PBS treated), 1.75uM LL-37 treated, 0.1ug/ml Poly(I:C) treated, and co-treated with 1.75uM LL-37 and 0.1ug/ml Poly(I:C).

Previous studies have shown that ischemia alters gene expression in normal and malignant tissues. There are no studies that evaluated effects of ischemia in renal tumors. This study examines the impact of ischemia and tissue procurement conditions on RNA integrity and gene expression in renal cell carcinoma.

Description
FUS-CHOP and EWS-CHOP balanced translocations characterize myxoid liposarcoma which encompasses myxoid (ML) and round cell (RC) variants initially believed to be distinct diseases. Currently, myxoid and RC liposarcoma are regarded to represent the well differentiated and the poorly differentiated ends, respectively, within spectrum of myxoid liposarcoma where the fusion proteins blocking lipogenic differentiation play a role in tumor initiation while molecular determinants associated to progression to RC remain poorly understood. Activation of AKT pathway sustained by PIK3CA and PTEN mutations and growth factor receptor signalling such as RET and IGF1R have been recently correlated with the increasing of aggressiveness and RC. Aim of the present study is to elucidate molecular events involved in driving round cell progression analyzing two small series of MLS selected to be representative of the two end of the gamut: the pure myxoid (0% of RC component) and RC with high cellular component (80%).
