miRNAs inherently alter the cellular environment by regulating target genes. miRNAs may also regulate other miRNAs, with far-reaching influence on miRNA and mRNA expression. We explore this realm of small RNA regulation with a focus on the role of the oncogenic miR-21 and its impact on other miRNA species.

全球 miRNA 与 miRNA 的相互作用：对 miR-21 的影响

miRNA 通过调节靶基因来固有地改变细胞环境。miRNAs 还可以调节其他 miRNAs，对 miRNA 和 mRNA 的表达产生深远的影响。我们探索了小 RNA 调控的这一领域，重点是致癌 miR-21 的作用及其对其他 miRNA 物种的影响。
