GenomicsChIP-seq study using a cell line model of ER_ AR+ molecular apocrine tumours (AR_FoxA1_molecular_apocrine)
Breast cancer is a heterogeneous disease and several distinct subtypes exist based on differential gene expression patterns. Molecular apocrine tumours were recently identified as an additional subgroup, characterised as oestrogen receptor negative and androgen receptor positive (ER_ AR+), but with ...

TranscriptomicsHistone H3 lysine 4 acetylation-methylation dynamics define breast cancer subtypes [RNA-seq]
The onset and progression of breast cancer are linked to genetic and epigenetic changes that alter the normal programming of cells. Epigenetic modifications of DNA and histones contribute to chromatin structure that results in the activation or repression of gene expression. Several epigenetic pathw...

GenomicsExploration of the redundancy between FOXA1 and AP2alpha in androgen receptor transcription complex
We performed a comparision of AR binding sites as well as the histone modifications H3K27 acetylation and H3K4 monomethylation in the presence and absence of FoxA1 in the molecular apocrine breast cancer cell line, MDA-MB-453. We also probed AP2alpha binding in asynchronous MDA-MB-453 cells.

GenomicsHistone H3 Lysine4 Acetylation-Methylation Dynamics Define Breast Cancer Subtypes [ChIP-seq]
The molecular signature at histone H3K4 involved in epigenetic regulation of normal (MCF10A) and transformed (MCF7, MDA-MB-231) breast cells using ChIP-Seq technology. This study examines the dynamic distribution of H3K4me3 and H3K4ac histone modification associated with active chromatin to provide...

ProteomicsEffect of Rosuvastatin on the Lipoprotein Proteome
Statins lower plasma cholesterol by as much as 50%, thus reducing future cardiovascular events. However, the physiological effects of statins are diverse and not all are related to LDL-C lowering. We performed a small clinical pilot study to assess the impact of statins on lipoprotein-associated pro...

GenomicsEffect of FOXA1 over-expression upon AR binding in AR-driven cancers
We performed androgen receptor (AR) ChIP-seq after GFP control or FOXA1 over-expression in two AR driven cancer models; LNCaP prostate cancer cell line and MDA-MB-453 molecular apocrine breast cancer cell line.

TranscriptomicsDeep Sequencing of the Small RNA Transcriptome of Normal and Malignant Human B cells Identifies Hundreds of Novel MicroRNAs: microarray analysis
A role for microRNAs has been recognized in nearly every biological system examined thus far. A complete delineation of their role must be preceded by the identification of all microRNAs present in any system. We elucidated the complete small RNA transcriptome of normal and malignant B cells through...

GenomicsGenetic and Functional Drivers of Diffuse Large B Cell Lymphoma
Diffuse large B cell lymphoma (DLBCL) is the most common hematologic malignancy and is characterized by a striking degree of heterogeneity. We enrolled a total of 1001 DLBCL patients and comprehensively defined the landscape of genetic mutations, copy number alterations and expression through whole-...
