While many American adults are trying to reduce cholesterol levels, certain cancerous tumors have a relentless appetite for the metabolite. Some tumor cells use as much cholesterol as they can access to accelerate their growth beyond the capabilities of normal cells.

Turning tumors’ cholesterol cravings into weakness
Scientists at Sanford Burnham Prebys Medical Discovery Institute and their collaborators at the University of Illinois Chicago have published findings in Science Advances regarding a potential method for turning the tables on these tumors by subverting their cholesterol cravings. The researchers revealed new insights into enzymes that help move cholesterol around cells...

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.
