Gene therapy doubles survival in recurrent glioblastoma

(University of Texas Health Science Center at San Antonio) An experimental gene therapy essentially doubled the overall survival of patients with recurrent glioblastoma compared to the current standard of care, a researcher said Oct. 1 at the Cancer Therapy &Research Center at The University of Texas Health Science Center at San Antonio.

Abstract Gene therapy has emerged as an alternative in the treatment of cancer, particularly in cases of resistance to chemo and radiotherapy. Different approaches to deliver genetic material to tumor tissues have been proposed, including the use of small non-coding RNAs due to their multiple mechanisms of action. However, such promise has shown limits in in vivo application related to RNA's biological instability and stimulation of immunity, urging the development of systems able to overcome those barriers. In this review, we discuss the use of RNA interference in cancer therapy with special attention to the role...

Abstract  Theranostics is a term used to describe the combination of diagnostic and therapeutic functions in a single agent. Ultrasound, for example, is a good tool for theranostics due to its multi-potency as both a diagnostic tool using sonography, and as a therapeutic, i.e., by high intensity focused ultrasound (HIFU). Likewise, microbubbles and nanobubbles are not only used as contrast imaging agents, but also as enhancers of drug delivery. Recently, the combination of these bubbles with low intensity ultrasound has been utilized as an effective drug delivery system. We have implemented a similar technique b...

In this study, we investigate mitochondrial energetics and mtDNA methylation in senescent cells, and evaluate the potential of humanin and MOTS-c as novel senolytics or SASP modulators that can alleviate symptoms of frailty and extend health span by targeting mitochondrial bioenergetics. Exercise versus the Hallmarks of Aging https://www.fightaging.org/archives/2018/06/exercise-versus-the-hallmarks-of-aging/ The paper I'll point out today walks through the ways in which exercise is known to beneficially affect the Hallmarks of Aging. The Hallmarks are a list of the significant causes of aging that I dis...

Abstract Cisplatin (CisPt) is one of the most effective antitumor drugs against a wide range of solid cancers, and recent studies have indicated that combination of CisPt and RNA interference (RNAi) agents would effectively enhance therapeutic index, while the development of simple yet robust dual-delivery systems still remains a challenge. Here, we demonstrated that platinated graphene oxide is an excellent platform to achieve such goal. Nano-Graphene oxide (NGO) was easily platinated by CisPt, and the resulting CisPt/NGO was characterized by several aspects. As a proof-of-concept, an antisense MicroRNA-21 (Anti-...

Publication date: 30 July 2018 Source:International Journal of Pharmaceutics, Volume 546, Issues 1–2 Author(s): Jun Li, Huamin Liang, Jing Liu, Ziyuan Wang Poly (amidoamine) (PAMAM) dendrimers are well-defined, highly branched macromolecules with numerous active amine groups on the surface. Because of their unique properties, PAMAM dendrimers have steadily grown in popularity in drug delivery, gene therapy, medical imaging and diagnostic application. This review focuses on the recent developments on the application in PAMAM dendrimers as effective carriers for drug and gene (pDNA, siRNA) delivery in cancer therapy, ...

Authors: Liu X, Hu J, Li Y, Cao W, Wang Y, Ma Z, Li F Abstract Development of an improved breast cancer therapy has been an elusive goal of cancer gene therapy for a long period of time. Human mesenchymal stem cells derived from umbilical cord (hUMSCs) genetically modified with the interleukin (IL)-18 gene (hUMSCs/IL-18) were previously demonstrated to be able to suppress the proliferation, migration and invasion of breast cancer cells in vitro. In the present study, the effect of hUMSCs/IL-18 on breast cancer in a mouse model was investigated. A total of 128 mice were divided into 2 studies (the early-effect study...

Abstract Gene therapy has demonstrated effectiveness in many genetic diseases as evidenced by recent clinical applications. Viral vectors have been extensively tested in clinical gene-therapy trials, but nonviral vectors such as cationic polymers or lipids are much less used due to their lower gene-transfection efficiencies. However, the advantages of nonviral vectors, such as easily tailored structures, nonimmunogenetics, and relatively low cost, still drive great efforts to improve their transfection efficiencies. A reverse question asks if nonviral vectors with current gene transfection efficiency can find appl...
