Molecular ‘detector’ recognizes most frequent cancer-mutation in cells, TP53 gene, and initiates to kill them. The alert goes on if the TP53 gene is mutated in cells. The molecular smoke detector works like a TP53 sensor, which monitors the correct function of the gene. A non-functional TP53 gene is going to activate the sensor, which initiates cell death. Results from this study from the research team of Prof. Frank Buchholz are now published in the journal Nature Communications.

A Yale-led study describes how EGFR cancer gene silences genes that typically suppress tumors. The finding may lead to the development of more effective, individualized treatment for patients with lung cancer and other cancer types. Mutations in the EGFR gene are linked to multiple cancer types, including cancers of the lung, brain, and breast. Yet scientists did not know precisely how EGFR represses genes that prevent cancers. The Yale team conducted multiple experiments and found that EGFR silences tumor suppressor genes in lung cancer and glioblastoma, a type of brain cancer.
