Deactivating cancer cell gene boosts immunotherapy for head and neck cancers
By targeting an enzyme that plays a key role in head and neck cancer cells, researchers from theUCLA School of Dentistry were able to significantly slow the growth and spread of tumors in mice and enhance the effectiveness of an immunotherapy to which these types of cancers often become resistant.Their findings,  published online in the journal Molecular Cell, could help researchers develop more refined approaches to combatting highly invasive head and neck squamous cell cancers, which primarily affect the mouth, nose and throat.Immunotherapy, which is used as a clinical treatment for various cancers, harnesses t...

New insight into how cancer spreads
(University of Colorado Anschutz Medical Campus) The transformation Ford and her team are studying happens when cells called epithelial cells, which are more adherent to one another and less likely to spread to other parts of the body, start to take on the characteristics of mesenchymal cells, which are more migratory and more likely to invade other parts of the body. This transformation is referred to as the epithelial-to-mesenchymal transition. (Source: EurekAlert! - Cancer)

Sporadic activation of an oxidative stress-dependent NRF2-p53 signaling network in breast epithelial spheroids and premalignancies
Breast and mammary epithelial cells experience different local environments during tissue development and tumorigenesis. Microenvironmental heterogeneity gives rise to distinct cell regulatory states whose identity and importance are just beginning to be appreciated. Cellular states diversify when clonal three-dimensional (3D) spheroids are cultured in basement membrane, and one such state is associated with stress tolerance and poor response to anticancer therapeutics. Here, we found that this state was jointly coordinated by the NRF2 and p53 pathways, which were costabilized by spontaneous oxidative stress within 3D cult...

Deregulation of ribosomal protein expression and translation promotes breast cancer metastasis
Circulating tumor cells (CTCs) are shed into the bloodstream from primary tumors, but only a small subset of these cells generates metastases.

Genes coding for ribosomal proteins and regulators of translation were enriched in this screen. Overexpression of RPL15, which encodes a component of the large ribosomal subunit, increased metastatic growth in multiple organs and selectively enhanced translation of other ribosomal proteins and cell cycle regulators.

Researchers create accurate model of organ scarring using stem cells in a lab
Every organ in the body is capable, to some extent, of repairing itself after an injury. As part of this process, scar tissue forms and then recedes to make room for normal tissue when healing is complete.However, when healing is disrupted — whether by chronic injury or disease — the cells that make up scar tissue can go rogue, continuously dividing and spreading until the scar eventually strangles the organ it was intended to help heal, which can lead to organ failure.That progressive, out-of-control scarring is called fibrosis, and it can occur in any organ in the body.

Reverse signaling by semaphorin 4C elicits SMAD1/5- and ID1/3-dependent invasive reprogramming in cancer cells
Semaphorins are a family of molecular signals that guide cell migration and are implicated in the regulation of cancer cells. In particular, transmembrane semaphorins are postulated to act as both ligands ("forward" mode) and signaling receptors ("reverse" mode); however, reverse semaphorin signaling in cancer is relatively less understood. Here, we identified a previously unknown function of transmembrane semaphorin 4C (Sema4C), acting in reverse mode, to elicit nonconventional TGF-β/BMP receptor activation and selective SMAD1/5 phosphorylation.
