中文简介: | 黑色素瘤抗原(MAGE)蛋白在所有真核生物中都是保守的,在哺乳动物中已经从单个基因扩展到40多个基因。虽然一些MAGE普遍表达,但大多数仅限于生殖细胞,并且在多种癌症类型中经常异常地重新激活。许多关于MAGE的初步研究集中在利用它们的抗原性,用癌症免疫疗法靶向它们,而这些蛋白质的生理功能仍然被掩盖。我们的发现首次揭示了MAGE的生理作用,并提供了一个概念突破,表明MAGE进化来保护生殖细胞免受压力,当被癌症劫持时,会促进致癌活性。这为表征新的压力保护途径、了解它们在治疗耐药性中的作用以及改进针对癌症的治疗方法打开了闸门。总之,我们利用MAGE蛋白在癌症和精子发生交叉点的独特位置,揭示了保护哺乳动物生殖系免受压力的新机制,发现了它们在癌症中的共存方式和原因。最终,我们希望将所学到的见解应用于癌症治疗和保持生育能力的进步,以造福人类和动物患者。 |
课程简介: | The melanoma antigen (MAGE) proteins are conserved in all eukaryotes and have expanded from a single gene to more than 40 genes in mammals. While some MAGEs are ubiquitously expressed, the majority are restricted to germ cells and often aberrantly re-activated in multiple cancer types. Much of the initial research on MAGEs focused on exploiting their antigenicity to target them with cancer immunotherapy, while the physiological function of these proteins remained overshadowed. Our discoveries shed the first insights into their physiological role and provided a conceptual breakthrough by showing that MAGEs evolved to protect germ cells against stress and when hijacked by cancer promote oncogenic activity. This opened floodgates in terms of characterizing novel stress-protective pathways, understanding their role in therapy resistance, and improving therapeutic approaches to target them in cancer. In all, we leverage the unique position of MAGE proteins at the intersection of cancer and spermatogenesis to uncover novel mechanisms that evolved to protect mammalian germline against stress, discover how and why they were co-opted in cancer. Ultimately, we want to apply the insights learned for the advancement of cancer treatment and fertility preservation to benefit human and animal patients. |
