Antibody–drug conjugates (ADCs) are a new class of anticancer agents that combine cytotoxic attached by linker to monoclonal antibody. These engineered drugs can selectively deliver payload targeted cancer cells and the local microenvironment (bystander effect), thereby increasing activity reducing off-target toxicity. The association ADCs with other anti-cancer therapies is therefore promising...

For targets that are homogenously expressed, such as CD19 on cells of the B lymphocyte lineage, immunotherapies can be highly effective. Targeting CD19 with blinatumomab, a CD19/CD3 bispecific antibody construct (BiTE®), or with chimeric antigen receptor T cells (CAR-T) has shown great promise for treating certain CD19-positive hematological malignancies. In contrast, solid tumors with heteroge...

Many cancers arise at sites of infection and inflammation. Cellular senescence, a permanent state of cell cycle arrest that provides a barrier against tumorigenesis, is accompanied by elevated proinflammatory cytokines such as IL1, IL6, IL8 and TNFα. Here we demonstrate that media conditioned by cells undergoing any of the three main forms of senescence, i.e. replicative, oncogene- and drug-ind...

We report evidence for a mechanism for the maintenance of long-range conserved synteny across vertebrate genomes. We found the largest mammal-teleost conserved chromosomal segments to be spanned by highly conserved noncoding elements (HCNEs), their developmental regulatory target genes, and phylogenetically and functionally unrelated "bystander" genes. Bystander genes are not specifically under...

The understanding of complex radiation responses in biological systems, such as non-targeted effects as represented by the bystander response, can be enhanced by the use of genetically amenable model organisms. Almost all bystander studies to date have been carried out by using conventional single-cell in vitro systems, which are useful tools to characterize basic cellular and molecular respons...

OBJECTIVE The herpes simplex virus thymidine kinase (HSVtk)/ganciclovir suicide gene therapy system has been considered as one of the most promising therapeutic strategies for malignant gliomas. We have been using HSVtk gene-transduced neural stem cells (NSCtk) that possess an ability to migrate toward a tumor mass for the treatment of experimental brain tumors. In the present study, we evaluat...

The radiation-induced bystander effect (RIBE) is a phenomenon whereby unexposed cells exhibit molecular symptoms of stress exposure when adjacent or nearby cells are traversed by ionizing radiation (IR). Recent data suggest that RIBE may be epigenetically mediated by microRNAs (miRNAs), which are small regulatory molecules that target messenger RNA transcripts for translational inhibition. Here...
