Core Tip

Core tip: The roles of the E2F transcription factors can vary significantly in malignancies of the digestive system, often dictating different outcomes in separate compartments of the gastrointestinal tract. Knowledge of the molecular status of the regulatory networks that E2Fs participate in is imperative to define their role. Therefore the use of proper molecular analysis to investigate these networks, complemented also by functional analysis in cellular and animal models, is essential. All in all, such an approach can define chronologically and provide a wider and more accurate view on the exact roles that E2Fs may exhibit in the development of specific digestive system malignancies.
