Неисправный ген репарации ДНК обнажил уязвимость рака

Ученые обнаружили, что ген, который обычно считается «хорошим парнем», защищающим ДНК, может стать опасным, когда клетки производят его в избытке. Ген EXO1 действует как молекулярные ножницы, помогающие восстанавливать ДНК, но при чрезмерном производстве он начинает разрезать ДНК, которую не должен, вызывая повреждения, связанные с раком.


Rogue DNA Repair Gene Exposes Cancer Weakness

Scientists have uncovered that a gene typically viewed as a beneficial DNA protector can turn hazardous when cells produce it excessively. The gene, known as EXO1, functions like molecular scissors that aid in DNA repair. However, when overproduced, it begins to indiscriminately cut DNA, leading to damage associated with cancer development.
