In vivo targeted and deterministic single-cell malignant transformation
Abstract
This important study employs an optogenetics approach aimed at activating oncogene (KRASG12V) expression in a single somatic cell, with a focus on following the progression of activated cell to examine tumourigenesis probabilities under altered tissue environments. Although the description of the methodologies applied is incomplete, the authors propose a mechanism whereby reactivation of re-programming factors correlates with the increased likelihood of a mutant cell undergoing malignant transformation. This work will be of interest to developmental and cancer biologists, especially in relation to the genetic tools described.
