Introduction Manual interpretation of immunohistochemistry (IHC) is a subjective, time-consuming and variable process, with an inherent intra-observer and inter-observer variability. Automated image analysis approaches offer the possibility of developing rapid, uniform indicators of IHC staining. In the present article we describe the development of a novel approach for automatically quantifying oestrogen...
The Wilms' tumor suppressor gene (WT1), a nuclear transcription factor, regulates the expression of the insulin-like growth factor (IGF) and transforming growth factor (TGF) systems, both of which are implicated in breast tumorigenesis. WT1 allelic integrity was examined by loss of heterozygosity (LOH) studies in formalin-fixed, paraffin-embedded (FFPE) ductal carcinoma in situ (DCIS, n = 20) and...
The humanMASproto-oncogene is situated at 6q25.3–q26, a region that is homologous to mouse chromosome 17 where two parentally imprinted genes (MasandIgf2r) have previously been identified. We investigated the imprinting status ofMASin adult lesions to establish the imprinting status of this gene in humans, as certain imprinted genes are known to have altered imprinting phenotypes in cancer. Of 14...
