Cancer therapy: Driving cancer cells to suicide

(Ludwig-Maximilians-Universität München) Researchers of Ludwig-Maximilians-Universitaet in Munich report that a new class of chemical compounds makes cancer cells more sensitive to chemotherapeutic drugs. They have also pinpointed the relevant target enzyme, thus identifying a new target for anti-tumor agents.

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Authors: Eckel HE, Bradley PJ Abstract Recent advances in minimal access surgery have shown promise in the treatment of limited hypopharyngeal lesions. In spite of their functionally excellent results in individual patients, it currently remains unlikely that these approaches will gain a more major universal impact on hypopharyngeal cancer care. In advanced stage hypopharyngeal cancer, the use of the traditional radical surgery, such as laryngo-pharyngectomy, is no longer accepted by many patients. In recent years, most would rather opt for less mutilating treatment, preferring a non-surgical option. Patients, fami...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...

Immortalization of plasma cells leads to Multiple Myeloma (MM). Signaling Lymphocyte Activation Molecule F7 (SLAMF7) is highly expressed on the malignant plasma cells that constitute Multiple Myeloma. The expression of SLAMF7 by MM cells and lack of expression on nonhematologic cells makes SLAMF7 a promising target for chimeric antigen receptor (CAR) T cell therapies for the treatment of MM.  In addition to expression on normal and malignant plasma cells, SLAMF7 is also known to be expressed on a variety of other leukocytes including most natural killer (NK) cells, some CD8+ T cells, a small fraction of CD4+ T cells, ...

(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 ...
