Redox Biology 2014 - Inflammation, Epidemiology

Redox Biology Recent advances in the biochemistry of redox-active species and radicals are beginning to be translated into improvements in prevention and treatment of cancer. Traditionally, reactive species such as superoxide, hydrogen peroxide and nitric oxide (NO) are associated with toxicity; however, NO is useful in the treatment of angina and cardiovascular disease. Also, NO is involved in cancer tumor angiogenesis and apoptosis of cancer cells. This course is an overview presenting how redox-active species and radicals are generated; their effects on the cellular and physiological level, how they alter carcinogenesis, angiogenesis and proliferation in animal models of cancer, and how NO alters patient imaging profiles and response to cancer therapy. It consists of two 1-hour lectures with ample time for discussion and analysis. The participation of postdoctoral and clinical fellows interested in redox biology is encouraged.

Authors: Di C, Zhang Q, Wang Y, Wang F, Chen Y, Gan L, Zhou R, Sun C, Li H, Zhang X, Yang H, Zhang H Abstract Exosomes are nanoscale vesicles shed from all cell types and play a major role in communication and transportation of materials between cells due to their ability to transfer proteins and nucleic acids from one cell to another. Analogous in size and function to synthetic nanoparticles, exosomes offer many advantages, rendering them the most promising candidates for targeted drug or gene delivery vehicles. Exosomes can also induce chemoresistance or radioresistance of tumor cells. Studies about the related m...

Publication date: Available online 15 November 2018Source: Saudi Journal of Biological SciencesAuthor(s): Yong Cao, Fei Dai, Yanmei Li, Lu Jia, Yunpeng Luan, Youjie ZhaoAbstractThe roots of Codonopis bulleynana Forest ex diels (cbFed), locally known as Tsoong, have been used as a tonic food. Tsoong has wide range of pharmacological effects, including anticancer effects. In the present study, the anticancer activity of Tsoong and its potential molecular mechanisms were investigated. Using high throughput sequencing the apoptotic pathway was ranked as one of the most important pathways and the differential expressions of apo...

Multifunctional nanoparticles in particular have been designed for targeted cancer therapy by modulating their physicochemical properties to be delivered to the target and activated by internal and/or external stimuli. This review will focus on the fundamental “chemical” design considerations of stimuli-responsive nanosystems to achieve favorable tumor targeting beyond biolog...

Abstract Self-hardening calcium phosphate cements present ideal bone tissue substitutes from the standpoints of bioactivity and biocompatibility, yet they suffer from (a) weak mechanical properties, (b) negligible osteoinduction without the use of exogenous growth factors, and (c) a lack of intrinsic antibacterial activity. Here we attempt to improve on these deficiencies by studying the properties of self-setting Fe-doped bone-integrative cements containing two different concentrations of the dopant: 0.49 and 1.09 wt% Fe. The hardening process, which involved the transformation of Fe-doped β-tricalcium pho...

In this study, immunohistochemistry was performed to examine the expression of GARP and Foxp3 in 19 human PTC tissues (including 10 cases with and 9 cases without lymph node metastasis) and 20 benign thyroid diseases (including 10 cases with nodular goiter and 10 cases with adenoma). Compared with benign thyroid diseases, we found a significant increase in the expression of GARP in PTC. Increased GARP expression in PTC was positively correlated with increased expression of Foxp3, which is very important for development of Tregs. But, there is no significant association of elevated expression of GARP with lymph node metasta...

Authors: Shen T, Guo Q Abstract Proline-rich tyrosine kinase 2 (Pyk2) plays essential roles in tumorigenesis and tumor progression. Pyk2 serves as a non-receptor tyrosine kinase regulating tumor cell survival, proliferation, migration, invasion, metastasis, and chemo-resistance, and is associated with poor prognosis and shortened survival in various cancer types. Thus, Pyk2 has been traditionally regarded as an oncogene and potential therapeutic target for cancers. However, a few studies have also demonstrated that Pyk2 exerts tumor-suppressive effects in some cancers, and anti-cancer treatment of Pyk2 inhibitors m...
