MIRO2 promotes cancer invasion and metastasis via MYO9B suppression of RhoA activity.

Metastasis to vital organs remains the leading cause of cancer-related deaths, emphasizing an urgent need for actionable targets in advanced-stage cancer. The role of mitochondrial Rho GTPase 2 (MIRO2) in prostate cancer growth was recently reported; however, whether MIRO2 is important for additional steps in the metastatic cascade is unknown. Here, we show that knockdown of MIRO2 ubiquitously reduces tumor cell invasion in vitro and suppresses metastatic burden in prostate and breast cancer mouse models.

Breaking down barriers: A qualitative study of the influence of clinical space design on teamwork.

Background: Delivery of safe maternity care requires not only individual competence but collective team work, influenced by knowledge, team culture and physical working spaces. The ideal layout for a birthing unit is not known, but deliberate changes to the built environment can influence patient care.

Aims: To explore the impact of creation of an open 'hub' on maternity team culture in a tertiary birthing unit and how physical changes to the environment shape values and practice.

Dependence of PAX3-FOXO1 chromatin occupancy on ETS1 at important disease-promoting genes exposes new targetable vulnerability in Fusion-Positive Rhabdomyosarcoma.

Rhabdomyosarcoma (RMS), a malignancy of impaired myogenic differentiation, is the most common soft tissue pediatric cancer. PAX3-FOXO1 oncofusions drive the majority of the clinically more aggressive fusion-positive rhabdomyosarcoma (FP-RMS). Recent studies have established an epigenetic basis for PAX3-FOXO1-driven oncogenic processes.

Remembering Hypoxia: Uncovering the Long-Term Effects of Transient Oxygen Deprivation on IFN Signaling and Progression of Breast Cancer.

Hypoxia occurs in 90% of solid tumors and is strongly associated with an increased propensity for metastasis. Hypoxia induces tumor progression largely through inducing HIF-mediated transcription, resulting in alterations to tumor cell metabolism, as well as increases in migration and invasion. Hypoxia also results in a myriad of changes to the tumor microenvironment (TME).

An EYA3/NF-κB/CCL2 signaling axis suppresses cytotoxic NK cells in the pre-metastatic niche to promote triple negative breast cancer metastasis.

Unlabelled: Patients with Triple Negative Breast Cancer (TNBC) exhibit high rates of metastases and poor prognoses. The Eyes absent (EYA) family of proteins are developmental transcriptional cofactors/phosphatases that are re-expressed and/or upregulated in numerous cancers. Herein, we demonstrate that EYA3 correlates with decreased survival in breast cancer, and that it strongly, and specifically, regulates metastasis via a novel mechanism that involves NF-kB signaling and an altered innate immune profile at the pre-metastatic niche (PMN).
