Abstract

MiRNAs play crucial roles in a broad spectrum of biological processes, both physiological and pathological. Different reports implicate miR-205 in the control of breast stem cell properties. Differential miR-205 expression has been observed in different stages of mammary gland development and maturation. However, a functional role in this process has not been clearly demonstrated. We generated an miR-205 knockout in the FVB/N mouse strain, which is viable and characterized by enhanced mammary gland development. Indeed, mammary glands of miR-205 −/− female mice at different ages (1.5 and 5.5 months) show increased outgrowth and branching. This evidence is consistent with our previously reported data demonstrating the direct miR-205-mediated targeting of HER3, a master regulator of mammary gland development, and the oncosuppressive activity of this microRNA in different types of breast cancer.

基因缺失 miR-205 会导致乳腺发育加快

MiRNA 在生理和病理等广泛的生物过程中发挥着至关重要的作用。不同的报告显示，miR-205 与乳腺干细胞特性的控制有关。在乳腺发育和成熟的不同阶段，已观察到不同的 miR-205 表达。然而，miR-205在这一过程中的功能性作用尚未得到明确证实。我们在 FVB/N 小鼠品系中产生了一种 miR-205 基因敲除小鼠，这种小鼠存活率高，乳腺发育增强。事实上，miR-205 -/-雌性小鼠在不同年龄段（1.5 个月和 5.5 个月）的乳腺显示出更多的外生和分支。这一证据与我们之前报道的数据一致，即 miR-205 介导的直接靶向 HER3（乳腺发育的主调控因子）以及该 microRNA 在不同类型乳腺癌中的抑制活性。
