Axin2-mTurquoise2: A novel reporter mouse model for the detection of canonical Wnt signalling.

The canonical Wnt signalling pathway has been implicated in organogenesis and self-renewal of essentially all stem cell systems. In vivo reporter systems are crucial to assess the role of Wnt signalling in the biology and pathology of stem cell systems. We set out to develop a Turquoise (TQ) fluorescent protein based Wnt reporter.

Sensitive and specific KRAS somatic mutation analysis on whole-genome amplified DNA from archival tissues.

Kirsten RAS (KRAS) is a small GTPase that plays a key role in Ras/mitogen-activated protein kinase signaling; somatic mutations in KRAS are frequently found in many cancers. The most common KRAS mutations result in a constitutively active protein. Accurate detection of KRAS mutations is pivotal to the molecular diagnosis of cancer and may guide proper treatment selection.
