Nature:早期肺癌会诱导周围成纤维细胞打造支持性的“癌前生态位”

当我们谈起癌症,往往首先想到的是基因突变。即,某个关键基因出了差错,细胞开始不受控制地增殖。但越来越多的研究表明,仅凭一些突变远不足以让一个细胞成为恶性肿瘤。细胞的命运,同样取决于它所处的微环境。微环境中的成纤维细胞、免疫细胞和细胞外基质,会深刻影响突变细胞能否存活、扩张乃至最终恶变。问题在于,这个微环境是怎么被改造成肿瘤友好型的?是肿瘤成形之后才开始重塑,还是更早?如果能够找到这个时间窗口,理论

NEJM:新型药物setidegrasib直接降解KRAS G12D蛋白,为肺癌和胰腺癌带来早期希望

KRAS是人类癌症中最常见的突变致癌基因之一,被称为“死星”(Death Star)因其蛋白结构光滑、缺乏传统药物结合口袋,长期以来被认为是“不可成药”的。KRAS G12D是KRAS突变中最常见的一种亚型,在胰腺癌中发生率高达40%,在非小细胞肺癌中约5%。近年来针对KRAS G12C突变的药物(如sotorasib、adagrasib)已获批,但G12D突变由于化学结构差异,一直缺乏有效靶向药

PNAS:给肿瘤“关灯”,香港大学戴宏杰团队设计“章鱼”探针,让癌细胞在特殊光线下无处遁形,精准指导手术切除

在肿瘤外科手术中,如何精确地术中描绘恶性肿瘤以实现完全切除且避免过度切除,一直是一项挑战。近红外二区(NIR-II,1,000至3,000 nm)成像能够实现深层组织的高对比度可视化,但其临床转化因缺乏稳健的探针而受限。Cytalux作为首个获批用于临床的靶向叶酸受体(FR)阳性癌症的近红外一区(NIR-I,700至1,000 nm)探针,其成像深度浅且肿瘤与正常组织对比度低。 2026年4月28
