Medical researchers from MSU suggested a new approach of targeted cancer therapy

(Lomonosov Moscow State University) A team from the Faculty of Medicine, MSU has analysed a link between the p53 protein, tumor dissemination and 'cell suicide' and discussed possible approaches to predict metastases development and their treatment. They also discussed new chemical compounds that might influence the process of metastasis. The study was supported by a grant from Russian Science Foundation (RSF). The results were published in the Cancers journal.

Oisin Biotechnologies developers a programmable suicide gene therapy platform, initially used to clear senescent cells from old tissues and thereby produce rejuvenation. Since this approach can also be directed to kill cancerous cells, and with little alteration to the original details of senescent cell targeting, a spinoff company OncoSenX was formed to undertake that line of development. This class of therapy should be broadly applicable to many types of cancer, with little customization required: it currently targets a common mechanism that appears near universally across cancer types. OncoSenX is a late stage ...

In this study, we used a directed evolution process, pooling different strains of VACV, including Copenhagen, Western Reserve and Wyeth strains and the attenuated modified vaccinia virus Ankara (MVA), to generate a new recombinant poxvirus with increased oncolytic properties. Through selective pressure, a chimeric VACV, deVV5, with increased cancer cell killing capacity and tumor selectivity in vitro was derived. The chimeric viral genome contains sequences of all parental strains. To further improve the tumor selectivity and anti-tumor activity of deVV5, we generated a thymidine kinase (TK)-deleted chimeric virus armed wi...

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 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...

This recent interview with Gary Hudson of Oisin Biotechnologies covers a range of topics; there is a lot more to it than is quoted here. The company is working on the application of a programmable gene therapy to the targeted destruction of senescent and cancerous cells. Since the approach can be adjusted to kill cells that express significant amounts of any arbitrarily selected target protein, it can in principle be adapted to destroy other types of unwanted cell. The immune system in older individuals or patients with autoimmune diseases, for example, contains any number of problem cells that it would be beneficial to re...

In this study, we did not observe significant age-dependent upregulation of the prominent SASP cytokine Il6 in any tissue, although an upward trend was observed that was consistent in magnitude with previous observations in the heart and kidney. This modest age-related upward trend could be explained by a previous report which demonstrated that senescent cell-secreted IL-6 acts in an autocrine manner, reinforcing the senescent state, rather than inducing senescence or promoting dysfunction in neighboring cells. The decreased expression of Il6 with age we observed in the hypothalamus could be indicative of a lack or ...

The Undoing Aging conference in Berlin is presently underway, a gathering of everyone who is anyone in the rejuvenation research community. It is hosted jointly by the SENS Research Foundation and the Forever Healthy Foundation, and is a unification of the varied themes of the past fifteen years of SENS conferences: the science of aging and its treatment from the earlier SENS conference series mixed with the industry, startup, and commercial development focus of the Rejuvenation Biotechnology series of recent years. The first rejuvenation therapies to be implemented and shown to work, those based on clearance of sen...

Prabhakar Aim Deformity in the cellular homeostatic event associated with cell survival and apoptosis are committing factors for carcinogenesis. Interventions of these events by pharmacologically active agent gain predominance in cancer treatment. In current investigation Solanidine, a steroidal alkaloid was evaluated on tumorigenesis by targeting death signal using multiple tumor cells and model systems. Main methods Anti-proliferative effect was evaluated using cytoto...

Discussion of advocacy for the cause is a usual feature of our community, as we try things and attempt to make progress in persuading the world that rejuvenation research is plausible, practical, and necessary. There are more people engaged in advocacy now than at any time in the past decade, and so discussions of strategy come up often. New ventures kicked off in 2017 include the Geroscience online magazine, and among the existing ventures the LEAF / Lifespan.io volunteers seem to be hitting their stride. The mainstream media continues to be as much a hindrance as a help, and where it is a help you will usually find Aubre...
