Celebrating James Marden: A Decade of Impact and a Lifetime of Achievement

New research shows how lung cancer cells can survive better and exhibit less cell damage when exposed to cigarette smoke in cell culture experiments compared to non-cancerous lung cells. Image shows non-cancerous lung cells (left) and lung cancer cells (right), subjected to the same concentration of cigarette smoke condensate. Non-cancerous cells have more pronounced protein aggregation granules (shown with an arrow), stained by Proteostat, a type of cell damage that can eventually lead to cell death.
