Long-range epigenetic silencing of chromosome 5q31 protocadherins is involved in early and late stages of colorectal tumorigenesis through modulation of oncogenic pathways (2012)
Journal Article

Loss of tumor suppressor gene function can occur as a result of epigenetic silencing of large chromosomal regions, referred to as long-range epigenetic silencing (LRES) and genome-wide analyses have revealed that LRES is present in many cancer types....

β-catenin represses expression of the tumour suppressor 15-prostaglandin dehydrogenase in the normal intestinal epithelium and colorectal tumour cells (2011)
Journal Article

Background: Cyclooxygenase-2 (COX-2) overexpression in colorectal cancer increases levels of its protumorigenic product prostaglandin E2 (PGE2). The recently identified colorectal tumour suppressor 15-prostaglandin dehydrogenase (15-PGDH) catalyses p...

Colon tumour cells increase PGE 2 by regulating COX-2 and 15-PGDH to promote survival during the microenvironmental stress of glucose deprivation (2011)
Journal Article

Due to poor tumour-associated vasculature, tumour cells are subjected to a fluctuating microenvironment with periods of limited oxygen and glucose availability. Adaptive mechanisms to adverse microenvironments are important for tumour cell survival....

The endogenous cannabinoid, anandamide, induces COX-2-dependent cell death in apoptosis-resistant colon cancer cells (2010)
Journal Article

Despite recent advances in understanding colorectal tumour biology, there is still a need to improve the 5-year survival rate of patients with colorectal cancer as approximately 40% of patients presenting with advanced disease will remain resistant t...

The proapoptotic BH3-only protein Bim is downregulated in a subset of colorectal cancers and is repressed by antiapoptotic COX-2/PGE2 signalling in colorectal adenoma cells (2010)
Journal Article

Overexpression of cyclooxygenase-2 (COX-2) and elevated levels of its enzymatic product prostaglandin E2 (PGE 2) occur in the majority of colorectal cancers and have important roles in colorectal tumorigenesis. However, despite the established prosur...
