A research team led by Professor Matthew D. Shoulders investigated the role of the proteostasis network—a system of cellular chaperone proteins that assist proper protein folding—in enabling cancer cells to persist despite aggressive mutations. Their findings, published in Molecular Cell in January 2026, focus on mutations in the tumor suppressor gene TP53 (p53), known as the guardian of the genome.
The study suggests cancer cells upregulate chaperone activity, allowing even dominant-negative p53 mutants, which interfere with healthy p53, to survive by maintaining correct folding. This effectively dismantles the cell’s primary defense against uncontrolled growth and provides an environment that tolerates dangerous mutations, deepening understanding of cancer evolution and resistance.
