Molecular 'self-destruct' switch discovered: How stressed cells decide between survival and death
A new study from Ben-Gurion University of the Negev (BGU) has identified a molecular switch that controls whether stressed human cells activate a survival mechanism or trigger programmed cell death (apoptosis). The findings, published in Redox Biology, provide insights that could help overcome chemotherapy resistance in aggressive tumors.
A groundbreaking study from Ben-Gurion University of the Negev has unveiled a molecular switch that determines whether stressed human cells opt for survival or undergo programmed cell death (apoptosis). Led by Dr. Aeid Igbaria, the research team identified that the cell's chemical redox balance plays a crucial role in this decision-making process.
Under moderate stress, the cell safeguards itself with molecular chaperones, while extreme stress disrupts these protectors, triggering apoptosis. The findings, published in Redox Biology, could potentially overcome chemotherapy resistance in aggressive tumors. The study also revealed that cancer cells exploit this pathway to resist drug treatments, making it a promising therapeutic target.
