  "textContent": "A research team has discovered a crucial mechanism that underlies chemotherapy resistance and metastasis in small cell lung cancer (SCLC). Their study shows that the silencing of the RASA4 gene through epigenetic mechanisms plays a crucial role in driving disease progression. The findings were published in Communications Biology on December 31.",
