Description
Hepatoblastoma (HB) is the most common liver cancer in children, but few pre-treatment tumors have been molecularly profiled. Consequently, there are no validated prognostic or therapeutic biomarkers for HB patients. We report on molecular analysis of 88 clinically-annotated HB tumors. This analysis pointed to three risk-stratifying molecular subtypeslow, intermediate and high riskthat are characterized by differential activation of hepatic progenitor cell markers and metabolic pathways. High-risk tumors are characterized by high NFE2L2 activity and LIN28B, HMGA2, SALL4 and AFP expression, low let-7 expression and HNF1A activity, and high coordinated expression of oncofetal proteins and stem cell markers. Tests on a 35 HB validation set supported these genes as prognostic biomarkers.

Illumina HiSeq 2000
Description
Precursor T-cell lymphoblastic neoplasms are aggressive haematological neoplasm that most often manifest with extensive marrow and blood affectation (T-cell acute lymphoblastic leukaemia or T-ALL) or less commonly as a thymic mass with limited bone marrow infiltration (T-cell lymphoblastic lymphoma or T-LBL). Here we show data from RNA-Seq in a sample series of T-LBL from Spanish patients.The goal was to determine the levels of expression of coding genes and microRNAs, and to identify all genetic variants including SNVs, indels, and fusion transcripts. Overall design: Expression data were determined by comparson of each tumour sample with two control thymuses (404 and 405). Genetic variants were determined by comparison of tumour sequences with canonical ENSEMBL normal-references of each gene.

Description
Trastuzumab improves survival outcomes in patients with HER2+ metastatic breast cancer. Some of these patients may become long-term survivors. The Long-Her study was designed to identify clinical and molecular markers that could differentiate long-term survivors from patients having early progression to trastuzumab.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Hutchinson-Gilford Progeria Syndrome (HGPS) is caused by a point mutation in the LMNA gene that activates a cryptic donor splice site and yields a truncated form of prelamin A called progerin. Small amounts of progerin are also produced during normal aging. Studies with mouse models of HGPS have allowed the recent development of the first therapeutic approaches for this disease. However, none of these earlier works have addressed the aberrant and pathogenic LMNA splicing observed in HGPS patients because of the lack of an appropriate mouse model. We report herein a genetically modified mouse strain that carries the HGPS mutation. These mice accumulate progerin, present histological and transcriptional alterations characteristic of progeroid models, and phenocopy the main clinical manifestations of human HGPS, including shortened life span and bone and cardiovascular aberrations. By using this animal model, we have developed an antisense morpholinobased therapy that prevents the pathogenic Lmna splicing, dramatically reducing the accumulation of progerin and its associated nuclear defects. Treatment of mutant mice with these morpholinos led to a marked amelioration of their progeroid phenotype and substantially extended their life span, supporting the effectiveness of antisense oligonucleotidebased therapies for treating human diseases of accelerated aging.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
The role of ERbeta2 in zebrafish larvae was investigated by injection of a Morpholino against ERbeta2. After 72hpf, the morphants showed a strong disruption in their sensory systems. ERbeta2 has been shown to be needed for the normal functioning of the sensory system organs, the neuromasts. The mechanisms involved in the neuromast disruption in ERbeta2 morphants was identified by microarrays gene screening. After comparison of two screening with low and hign concentration of Morpholinos, genes that were present in the two microarrays screening were selected. The genes were then chosen by relevance for the mechanisms involved in the role of ERbeta2 in neuromast development. The ngn1 transcription factor, Notch3 and Notch1a showed to be up-regulated, also confirmed by in situ hybridization. The Notch signaling is known to be involved in cell fate in developing neuromasts. The overall conclusion is that ERbeta2 by interacting with the notch signaling pathways is critical for normal development of the neuromast of the lateral line in zebrafish.

Description
Background: Transcriptome variability is due to genetic and environmental causes, much like any other complex phenotype. Ascertaining the transcriptome differences between individuals is an important step to understand how selection and genetic drift may affect gene expression. To that end, extant divergent livestock breeds offer an ideal genetic material.
