KRAS and cancer: Since KRAS mutations play a key role in tumorigenesis and cancer progression by altering cell signaling, leading to uncontrolled proliferation and resistance to standard therapies, and they can be found in as much as 20–25% of all human tumors [5], our simple in silico model was built, containing the main elements of the regulatory network to provide a detailed qualitative description of the control network in KRAS mutant cancer cells.
