Colorectal cancer (CRC) is one of the leading causes of cancer deaths in Western countries. A significant number of CRC patients undergoing curatively intended surgery subsequently develop recurrence and die from the disease. MicroRNAs (miRNAs) are aberrantly expressed in cancers and appear to have both diagnostic and prognostic significance. In ...

Liver transplantation (LT) provides optimal long-term disease-free survival for hepatocellular carcinoma (HCC). High pre-LT alpha-fetoprotein (AFP) has been associated with HCC recurrence, but it is unclear whether a drop in AFP or locoregional therapy impacts survival/recurrence after LT. LT-recipients transplanted for HCC in three centers (UNOS Region 6) were reviewed ...

Activated oncogenes restrict cell proliferation and transformation by triggering a DNA damage-dependent senescence checkpoint in response to DNA hyper-replication. Here we show that loss of the p16(INK) (4a) cyclin dependent kinase inhibitor and melanoma tumour suppressor facilitates a DNA damage response after a hyper-replicative phase in human melanocytes. Unlike cells ...

Vascular patterning involves sprouting of blood vessels, which is governed by orchestrated communication between cells in the surrounding tissue and endothelial cells (ECs) lining the blood vessels. Single ECs are selected for sprouting by hypoxia-induced stimuli and become the 'tip' or leader cell that guides new sprouts. The 'stalk' or ...
