Cancer-fighting T cells are smarter, stronger than experts thought

(Vanderbilt University) It takes a minuscule amount of force to make T cells behave in the lab as they behave in the body. That finding is a leap forward in cancer therapy research.

Ectopic expression of E3 ubiquitin-protein ligase 2 in glioma and enhances resistance to apoptosis through activating nuclear factor κ-light-chain-enhancer of B cells. Oncol Lett. 2018 Oct;16(4):4391-4399 Authors: Bai J, Xiao L, Tao Z, Cao B, Han Y, Fan W, Kong X, Ma X, Gao Y, Bi L, Chen W, Shi B, Liu X Abstract Nuclear factor κ-light-chain-enhancer of B cells (NF-κB) is one of the most important tumorigenic factors. Although it has been established that NF-κB is overly activated in human glioma cells, the molecular mechanisms that lead to the signal transduction to NF-κB ...

Authors: Yu Y, Cui J Abstract Modulation of the tumor microenvironment is becoming an increasingly popular research topic in the field of immunotherapy, and studies regarding immune checkpoint blockades and cancer immunotherapy have pushed cancer immunotherapy to a climax. Simultaneously, the manipulation of the immune regulatory pathway can create an effective immunotherapy strategy; however, the tumor microenvironment serves an important role in suppressing the antitumor immunity by its significant heterogeneity. A number of patients with cancer do not have a good response to monotherapy approaches; therefore, co...

This study manipulated a chrysin loaded bovine serum albumin nanoparticles (BSA NPs), which could solubilize the poorly water-soluble drug and increase the therapeutic efficacy of the drug. Chrysin (5, 7-dihydroxyflavone) is a natural flavonoid which have some significant biological effects on the processes of chemical defense. Chrysin loaded bovine serum albumin nanoparticles (Chrysin-BSA NPs) were synthesized by a simple desolvation procedure. The resultant Chrysin-BSA NPs showed a spherical shape, with a diameter of 97.5 ± 5.75 nm (mean ± SD) nm and a ζ-potential of - 11 mV. The in vitro d...

However, high concentration of reductive glutathione (GSH) in tumor site is an enemy, which can decrease the PDT efficacy due to ROS consumption property of reductive GSH. To overcome the problem, here we design an innovative nanoplatform, which could integrate PDT, chemo...

We report the case of an acute coronary syndrome presumably induced by 5-FU in a patient with previously unknown and asymptomatic corotabelnary artery disease and with an estimated intermediate risk for cardiovascular events. Pre-chemotherapy risk assessment and optimal patient care are still not standardized in this clinical scenario.ResumoO 5-flurouracilo é um agente de primeira linha no tratamento de várias neoplasias. Associa-se frequentemente a toxicidade cardíaca, particularmente em doentes com doença coronária. O caso apresentado ilustra uma síndrome coronária aguda p...

Reasoning that glutathione (GSH) and reactive oxygen species (ROS) are highly upgraded in tumor tissues which makes them attractive targets for drug delivery system, we designed and synthetized a novel prodrug which utilized mono thioether bond as a linker to bridge ...

PEG-POEU-PEG could further self-assemble into nano-scaled micelles. Ortho ester degradation in these micelles was significantly accelerated at pH 5.0...
