Stromal cells are essential for tumor growth. Stromal cells interact with cancer cells during tumor growth and progression. We report here the development of a tri-color imageable mouse model to visualize the interaction between host cells and cancer cells. To observe subcellular cancer cell dynamics in vivo, HT-1080 human fibrosarcoma cells were labeled in the nucleus with histone H2B-green fl...

Numerous applications of conventional and biogenic magnetic nanoparticles (MNPs), such as in diagnostics, immunomagnetic separations, and magnetic cell labeling, require the immobilization of antibodies. This is usually accomplished by chemical conjugation, which, however, has several disadvantages, such as poor efficiency and the need for coupling chemistry. Here, we describe a novel strategy ...

Background: It is known that antituberculosis drugs initially induce liver injury, and then the liver progressively adapts to the drug and mitigates the drug-induced liver injury. This study aimed to explore the molecular mechanisms responsible for liver adaptation to Rifampicin (RFP). Methods: RFP was administered at a dose of 100 mg/kg·d to rats for 7 weeks. On days 0, 7, 14, 21, 28, 35, 42, ...

Efficient delivery of tumor-specific antigens (TSAs) to lymph nodes (LNs) is essential to eliciting robust immune response for cancer immunotherapy but still remains unsolved. Herein, we evaluated the direct LN-targeting performance of four different protein nanoparticles with different size, shape, and origin [Escherichia coli DNA binding protein (DPS), Thermoplasma acidophilum proteasome (PTS...

In this study we demonstrate the ability of a novel, p.o.-administered cytosine analogue, CS-682, to effectively prolong survival and inhibit metastatic growth in an imageable orthotopic mouse model of pancreatic cancer. MIA-PaCa-2-RFP pancreatic cancer cells were transduced with the Discosoma red fluorescent protein (RFP) and orthotopically implanted onto the pancreas of nude mice. Tumor RFP f...

Anti-cytokine therapies have substantially improved the treatment of inflammatory and autoimmune diseases. Cytokine-targeting drugs are usually biologics such as antibodies or other engineered proteins. Production of biologics, however, is complex and intricate and therefore expensive which might limit therapeutic application. To overcome this limitation we developed a strategy that involves th...

BACKGROUND Diabetes mellitus is associated with an increased risk of breast cancer, but studies of the effects of diabetes on the prognosis of women with breast cancer have yielded inconsistent findings. The present meta-analysis aimed to investigate the impact of preexisting diabetes on the prognosis in terms of overall survival (OS), disease-free survival (DFS), and relapse-free period (RFP) ...

Optimal feedback control of resistive-wall modes (RWM) is of common interest for toroidal fusion concepts that use conducting walls for stabilization of ideal MHD modes. From the RWM control point of view, the RFP situation is in many respects similar to the advanced tokamak situation in the presence of very low plasma rotation, where the most effective stabilizing mechanism is the feedback act...

AMPA receptors lacking the GluA2 subunit allow a significant influx of Ca(2+) ions. Although Ca(2+)-permeable AMPA receptors are a familiar feature at early stages of development, the functional significance of these receptors during the maturation of the nervous system remains to be established. Chicken lumbar motoneurons express Ca(2+)-permeable AMPA receptors at E6 but the Ca(2+) permeabilit...

Taste buds, the sensory organs for taste, have been described as arising solely from the surrounding epithelium, which is in distinction from other sensory receptors that are known to originate from neural precursors, i.e., neural ectoderm that includes neural crest (NC). Our previous study suggested a potential contribution of NC derived cells to early immature fungiform taste buds in late emb...
