By targeting BRAF V600E a human-relevant mutation known to potently activate MAP kinase to the mouse prostate epithelium, we show here that MAP kinase activation can drive aberration proliferation and basaloid hyperplasia, leading to emergence of invasive adenocarcinoma of the prostate gland with short latency and high penetrance without evidence of AKT activation.
The early to intermediate stages of the majority of colorectal tumours are thought to be driven by aberrations in the Wnt (APC, CTNNB1) and Ras (K-ras) pathways.
Some background: The last time the prices of oil and other commodities were this high, two and a half years ago, many commentators dismissed the price spike as an aberration driven by speculators.
The reported association modules indicated that gene/microRNA expressions in cancer were driven by diverse aberration mechanisms including copy number variations, mutations, DNA methylations, microRNA and transcription factor expressions.
This transition involves enormous remodeling of the cell and is likely driven by genetic aberrations, extracellular signals, and the activation of differentiation programs in the cancer cells.
During these events, a series of genetic and epigenetic aberrations driven by inflammation and oxidative stress contributes to the carcinogenesis.
During these events, the accumulation of genetic and epigenetic aberrations driven by inflammation, as well as acid and bile salt stimulation, contributes to the carcinogenesis.
These survival mechanisms include a reduced propensity for certain tumour cells to die under conditions of stress and may be driven by genetic aberrations such as loss of p53 function [ 164, 165].
These survival mechanisms include a reduced propensity for tumour cells to die under conditions of stress and may be driven by genetic aberrations such as the loss of p53 function (Yu et al, 2001, 2002).
Inherent in the development of target-based therapeutics is also the notion that this anticancer activity may be maximized by selectively treating patients whose tumors are particularly driven by the target aberration and would therefore be expected to respond most profoundly.
