Standard-of-care treatment for malignant mesothelioma could change significantly, depending upon the results of an upcoming clinical trial of two immunotherapy agents used in combination with chemotherapy. The mesothelioma clinical trial will involve pembrolizumab, also known by the brand name Keytruda, and its synergy with ONCOS-102, a lesser-known, genetically modified adenovirus. Individually, both have shown modest efficacy for mesothelioma patients when used with chemotherapy. Together, there is potential for a much greater impact in significantly extending patient survival. The clinical trial is a partnership between...

Authors: Eremina NV, Kazey VI, Mishugin SV, Leonenkov RV, Pushkar DY, Mett VL, Gudkov AV Abstract Toll-like receptor 5 (TLR5) controls endogenous immune responses to pathogens and is a promising target for pharmacological stimulation of anti-tumor immunity. Mobilan is an innovative gene therapy agent consisting of a non-replicating bicistronic adenovirus directing constitutive expression of human Toll-like receptor 5 (TLR5) and the secreted flagellin-based TLR5 agonist, 502s. In mice, Mobilan injection into prostate tumors resulted in autocrine TLR5 signaling, immune system activation, and suppression of tumor grow...

Authors: Xu SG, Yu JJ, Shi Q, Niu Q, Guo Z, Guo BY, Zhou GC, Gu X, Wu YX Abstract The present study aimed to construct conditionally replicative adenovirus (CRAds) carrying small hairpin (sh)RNA targeting enhancer of zeste homolog 2 (EZH2), in order to study its effect on inhibiting prostate cancer (PCa) cell growth and invasion. Immunohistochemical analyses of EZH2 was performed in tumor tissue samples from PCa and benign prostate hyperplasia (BPH). The human telomerase reverse transcriptase (hTERT) promoter was chosen to transcriptionally control EZH2 gene expression to obtain adenoviral replication (Ad‑hTERTâ€...

Herein we demonstrate that ultraviolet light–inactivated Herpes Simplex Virus-1 (UV-HSV-1) stimulates peripheral blood mononuclear cells (PBMCs) to lyse both androgen-sensitive and androgen-independent prostate cancer (PrCA) cell lines, but not the benign prostatic hyperplastic epithelial cell line, BPH-1, and is 1000–10,000-fold more potent at stimulating this killing than ultraviolet light-inactivated Vesicular Stomatitis Virus, adenovirus, reovirus or cytomegalovirus. Among PBMCs, natural killer (NK) cells appear to be a major cell type involved in this killing and UV-HSV-1 appears to directly and potently s...

Conclusion and Future Perspectives This review illustrates our current knowledge of USP7, including its source and characterization, structure, binding partners and substrates in various biological processes. Besides, how USP7 regulates various aspects of a cell under both normal and pathological states are elaborated in detail. As the processes of ubiquitination and deubiquitination are extremely dynamic and context-specific, a series of studies have linked USP7 to different cancers. The biology, particularly the immune oncology mechanisms, reveal that USP7 inhibitors would be useful drugs, thus it is vital to develop hi...

Ott Research Institute of Obstetrics, Gynecology and Reproductology, Saint Petersburg, Russia 2Department of Genetics and Biotechnology, Saint Petersburg State University, Saint Petersburg, Russia In the present review, we focus on the phenomenon of chromothripsis, a new type of complex chromosomal rearrangements. We discuss the challenges of chromothripsis detection and its distinction from other chromoanagenesis events. Along with already known causes and mechanisms, we introdu...
