Original Description (Extracted from the article) ... Using the human breast cancer cell line SKBR3 as a model for ERBB2 and ERBB3 dependence, infection of these cells with retroviral constructs expressing either miR-125a or miR-125b resulted in suppression of ERBB2 and ERBB3 at both the transcript and protein level. Luciferase constructs containing the 3' 3'-untranslated regions of ERBB2 and ERBB3 demonstrated 35% less activity in miR-125a- and miR-125b-expressing cells relative to controls. ...

Deregulation of micro-RNAs (miRNAs) is emerging as a major aspect of cancer etiology because their capacity to direct the translation and stability of targeted transcripts can dramatically influence cellular physiology. To explore the potential of exogenously applied miRNAs to suppress oncogenic proteins, the ERBB oncogene family was chosen with a bioinformatics search identifying targeting seed sequences for miR-125a and miR-125b within the 3'-untranslated regions of both ERBB2 and ERBB3. Using the human breast cancer cell line SKBR3 as a model for ERBB2 and ERBB3 dependence, infection of these cells with retroviral constructs expressing either miR-125a or miR-125b resulted in suppression of ERBB2 and ERBB3 at both the transcript and protein level. Luciferase constructs containing the 3' 3'-untranslated regions of ERBB2 and ERBB3 demonstrated approximately 35% less activity in miR-125a- and miR-125b-expressing cells relative to controls. Additionally, phosphorylation of ERK1/2 and AKT was suppressed in SKBR3 cells overexpressing either miR-125a or miR-125b. Consistent with suppression of both ERBB2 and ERBB3 signaling, miR-125a-or miR-125b-overexpressing SKBR3 cells were impaired in their anchorage-dependent growth and exhibited reduced migration and invasion capacities. Parallel studies performed on MCF10A cells demonstrated that miR-125a or miR-125b overexpression produced only marginal influences on the growth and migration of these non-transformed human mammary epithelial cells. These results illustrate the feasibility of using miRNAs as a therapeutic strategy to suppress oncogene expression and function.

Original Description (Extracted from the article) ... The importance of miRNAs not only as regulators but also as effectors of ErbB signalling is emphasized by miR-21, a key mediator of cancer cell growth and invasion whose expression is stimulated by EGFR/ErbB2. Studies are underway to modulate miRNA expression and activity in vivo with a view to developing therapeutics that can effectively block signalling pathways critical to tumour development and progression, although technical hurdles relating to delivery and tissue specificity are still to be overcome. As high-throughput miRNA profiling becomes feasible, a major goal is the identification of miRNA signatures that are predictive of treatment response, clinical outcome, or that can stratify tumour phenotypes. Should recent advances in understanding the basic science of miRNAs in cancer be translated to the clinic then there is the potential that they will transform cancer diagnosis and treatment. ...

Recent years have seen a massive expansion in our understanding of the biology of microRNAs (miRNAs) in cancer, through the identification of miRNAs with aberrant expression in specific cancers and the functional validation of their critical target molecules and cellular effects. In parallel, targeted therapeutic agents to block signalling pathways critical to tumour growth and progression have been developed but have yielded disappointing clinical results. The discovery of miRNAs that regulate ErbB signalling in cancer cells brings new hope that in the future these oncogenic pathways can be more effectively inhibited to improve patient outcomes.

MicroRNAs regulate networks of genes to orchestrate cellular functions. MiR-125b, the vertebrate homologue of the Caenorhabditis elegans microRNA lin-4, has been implicated in the regulation of neural and hematopoietic stem cell homeostasis, analogous to how lin-4 regulates stem cells in C. elegans. Depending on the cell context, miR-125b has been proposed to regulate both apoptosis and proliferation. Because the p53 network is a central regulator of both apoptosis and proliferation, the dual roles of miR-125b raise the question of what genes in the p53 network might be regulated by miR-125b. By using a gain- and loss-of-function screen for miR-125b targets in humans, mice, and zebrafish and by validating these targets with the luciferase assay and a novel miRNA pull-down assay, we demonstrate that miR-125b directly represses 20 novel targets in the p53 network. These targets include both apoptosis regulators like Bak1, Igfbp3, Itch, Puma, Prkra, Tp53inp1, Tp53, Zac1, and also cell-cycle regulators like cyclin C, Cdc25c, Cdkn2c, Edn1, Ppp1ca, Sel1l, in the p53 network. We found that, although each miRNA-target pair was seldom conserved, miR-125b regulation of the p53 pathway is conserved at the network level. Our results lead us to propose that miR-125b buffers and fine-tunes p53 network activity by regulating the dose of both proliferative and apoptotic regulators, with implications for tissue stem cell homeostasis and oncogenesis.
