Further investigations into FYB2’s specific molecular interactions could therefore offer new insights into its role in modulating tumor–immune cell interplay and ultimately in determining disease outcome.\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Peng Wang, Zengfeng Sun, Zhen Zhang, et al.
