Tracing PAKs from GI inflammation to cancer
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This review discusses p-21-activated kinases (PAKs) as effectors of Rac1/Cdc42 that relay signals from the cell membrane to the nucleus, driving pathways including mitogen-activated protein kinase, PI3K/AKT, NF-kB and Wnt/beta-catenin. The abstract states intestinal PAK1 expression increases with inflammation and malignant transformation, though the biological relevance of PAKs in GI disease development is incompletely understood. It highlights altered PAK activation in GI inflammation, its effect on oncogenic signalling, and discusses PAKs as targets of chemoprevention.
Abstract
P-21 activated kinases (PAKs) are effectors of Rac1/Cdc42 which coordinate signals from the cell membrane to the nucleus. Activation of PAKs drive important signalling pathways including mitogen activated protein kinase, phospoinositide 3-kinase (PI3K/AKT), NF-κB and Wnt/β-catenin. Intestinal PAK1 expression increases with inflammation and malignant transformation, although the biological relevance of PAKs in the development and progression of GI disease is only incompletely understood. This review highlights the importance of altered PAK activation within GI inflammation, emphasises its effect on oncogenic signalling and discusses PAKs as therapeutic targets of chemoprevention.
