Jargon: Tumour Suppressor (A gene whose underexpression can help drive cancer)

Tumour suppressor: a gene whose regular function is to inhibit the division of a cell. When the expression of this gene is blocked, the cell divides much more than it should, which can lead to cancer.

A useful analogy is that of a car. When the expression of a tumour suppressor is disrupted, it can be like removing your foot from the brake pedal when parked on a downward slope.
