microRNA簇miR-17-92的过表达与实体瘤和血液恶性肿瘤的发展有关。miR-17-92在淋巴瘤发生中的作用已被广泛研究;然而,由于miR-17-92失调引起的发育缺陷,其驱动肿瘤发生的能力直到最近才被确定。在这里,我们证明了miR-17-92在有限数量的造血细胞中的过表达足以引起B细胞恶性肿瘤。总之,我们的研究提供了一种新的和生理相关的模型,揭示了miR-17-92作为肿瘤发生驱动因素的强大能力。
The overexpression of microRNA cluster miR-17-92 has been implicated in development of solid tumors and hematological malignancies. The role of miR-17-92 in lymphomagenesis has been extensively investigated; however, because of the developmental defects caused by miR-17-92 dysregulation, its ability to drive tumorigenesis has remained undetermined until recently. Here we demonstrate that overexpression of miR-17-92 in a limited number of hematopoietic cells is sufficient to cause B cell malignancies. In sum, our study provides a novel and physiologically relevant model that exposes the potent ability of miR-17-92 to act as a driver of tumourigenesis.
