Cancer cell migration and invasion are initial steps for tumor metastasis, which increases patient mortality. The tumor microenvironment is characterized as being hypoxic and nutrient deficient. Previous studies have suggested that hypoxia induces tumor metastasis, while the low nutrient content is not beneficial for tumor metastasis. Thus, it is necessary to develop a simple probe to study the changes in cancer migration and invasion. Herein, we designed a nanoprobe based on gold nanoparticles (Au NPs) to monitor the effect of different oxygen and nutrient conditions on the migration and invasion of breast cancer cells through detecting the changes in levels of RAB-22a and MMP-2 mRNA in living cells. After incubating MCF-7 and MDA-MB-231 cells with different concentrations of oxygen and nutrients, fluorescence imaging assays were used to evaluate migration and invasion. This work provides a new insight in the effect of different tumor microenvironments on cell migration and invasion.

Biomaterials Science

Biomaterials Science is an international high impact journal exploring the science of biomaterials and their translation towards clinical use. Its scope encompasses new concepts in biomaterials design, studies into the interaction of biomaterials with the body, and the use of materials to answer fundamental biological questions. Papers do not necessarily need to report a new biomaterial but should provide novel insight into the biological applications of the biomaterial. Articles that primarily focus on demonstrating novel materials chemistry and bring a molecular picture to bear on a given material’s suitability as a biomaterial are more suited to our companion journal, Journal of Materials Chemistry B. Biomaterials Science publishes primary research and review-type articles in the following areas: molecular design of biomaterials, including translation of emerging chemistries to biomaterials science of cells and materials at the nanoscale and microscale materials as model systems for stem cell and human biology materials for tissue engineering and regenerative medicine (Nano)materials and (nano)systems for therapeutic delivery interactions at the biointerface biologically inspired and biomimetic materials, including bio-inspired self-assembly systems and cell-inspired synthetic tools next-generation biomaterials tools and methods
