The Macrophage Activator GcMAF-RF Enhances the Antitumor Effect of Karanahan Technology through Induction of M2-M1 Macrophage Reprogramming.

Macrophages are the immune cells of high-immunological plasticity, which can exert both pro- and anti-inflammatory activity, as well as repolarize their phenotype to the opposite or neutral one. In this regard, M2 macrophages of the tumor-associated stroma (TAS) are a promising therapeutic target in treating malignant neoplasms. Using FACS assay, we have estimated the CD11b+/Ly-6G+/Ly-6C+ fraction of macrophages from the peritoneum and TAS in intact healthy mice and those with developed Lewis carcinoma, both untreated and treated according to Karanahan technology in combination with group-specific macrophage activator (GcMAF-RF).

Efficacy of the new therapeutic approach in curing malignant neoplasms on the model of human glioblastoma.

Objective: Glioma is a highly invasive tumor, frequently disposed in essential areas of the brain, which makes its surgical excision extremely difficult; meanwhile adjuvant therapy remains quite ineffective.

Methods: In the current report, a new therapeutic approach in curing malignant neoplasms has been performed on the U87 human glioblastoma model. This approach, termed "Karanahan", is aimed at the eradication of cancer stem cells (CSCs), which were recently shown to be capable of internalizing fragments of extracellular double-stranded DNA.

[Characteristic of the active substance of the Saccharomyces cerevisiae preparation having radioprotective properties].

The paper describes some biological features of the radioprotective effect of double-stranded RNA preparation. It was found that yeast RNA preparation has a prolonged radioprotective effect after irradiation by a lethal dose of 9.4 Gy.

Characterization of biological peculiarities of the radioprotective activity of double-stranded RNA isolated from .

The Purpose Of The Article: Protection from ionizing radiation is the most important component in the curing malignant neoplasms, servicing atomic reactors, and resolving the situations associated with uncontrolled radioactive pollutions. In this regard, discovering new effective radioprotectors as well as novel principles of protecting living organisms from high-dose radiation is the most important factor, determining the new approaches in medical and technical usage of radiation.

Materials And Methods: Experimental animals were irradiated on the γ-emitter (Cs) with a dose of 9.

Approbation of the Cancer Treatment Approach Based on the Eradication of TAMRA+ Cancer Stem Cells in a Model of Murine Cyclophosphamide Resistant Lymphosarcoma.

Background/aim: We previously have described the "3+1" tumors cure approach consisting of individual time schedule of cyclophosphamide and dsDNA preparation administrations. The aim of the study was to adapt the "3+1" approach based on eradication of cancer stem cells to the model of murine ascitic cyclophosphamide-resistant lymphosarcoma (RLS).

Materials And Methods: Adaptation of the "3+1" approach includes the identification of the timing to disrupt the tumorigenic potential of a certain tumor.
