Junction opening protein boosts cancer-killing effect of oncolytic virus

(Mary Ann Liebert, Inc./Genetic Engineering News) A new study shows that the anti-tumor effect of oncolytic virus therapy is significantly greater in mice when the virus is genetically modified to express a junction opening (JO) protein, which helps the cancer-killing agent better penetrate solid tumors. The potential for JO to improve cancer therapy with various types of oncolytic viruses is described in Human Gene Therapy.

Background: Chimeric antigen receptor T cell (CART) therapy is revolutionizing modern cancer therapy, with two anti-CD19 CARTs FDA-approved for relapsed/refractory B cell lymphoma/leukemia and many other CARTs for solid and liquid tumors currently undergoing clinical trials. Our group recently demonstrated multiplexed CRISPR/Cas9 gene-editing of anti-CD7 CARTs to produce CD7 and T cell receptor alpha constant (TRAC)-deleted "off-the-shelf" universal (U)CART7s that effectively kill CD7+ T cell lymphoma in vivo without causing GVHD or fratricide (Cooper et al, Leukemia, 2018). However, in current clinical practice,...

Authors: Assani G, Xiong Y, Zhou F, Zhou Y Abstract Cancer is one of the leading causes of death in the world. Many strategies of cancer treatment such as radiotherapy which plays a key role in cancer treatment are developed and used nowadays. However, the side effects post-cancer radiotherapy and cancer radioresistance are two major causes of the limitation of cancer radiotherapy effectiveness in the cancer patients. Moreover, reduction of the limitation of cancer radiotherapy effectiveness by reducing the side effects post-cancer radiotherapy and cancer radioresistance is the aim of several radiotherapy-oncologic...

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.

Abstract Exosomes play a critical role in intercellular communication between cancer cells and their environments. These secreted nanovesicles can transfer different cargos such as mRNAs, proteins and microRNA (miRNA) to recipient cells. Exosomal miRNAs (exomiRs) derived from tumor cells have emerged as key players in cancer promotion via impairment of the immune system response, tumor growth, metastasis, angiogenesis, and chemotherapeutic drug resistance. Moreover, since dysregulation of miRNA expression in tumor cells can be reflected by distinct profiles of exomiRs extracted from the bodily fluids of cancer pat...

acute;rrez L, de la Fuente JM Abstract Magnetic nanoparticles (MNPs) are promising tools for a wide array of biomedical applications. One of their most outstanding properties is the ability to generate heat when exposed to alternating magnetic fields, usually exploited in magnetic hyperthermia therapy of cancer. In this contribution, we provide a critical review of the use of MNPs and magnetic hyperthermia as drug release and gene expression triggers for cancer therapy. Several strategies for the release of chemotherapeutic drugs from thermo-responsive matrices are discussed, providing representative examples of t...

Development of T-cell based immunotherapies for the treatment of various cancers has been challenged for decades by the lack of target antigens that are only expressed by cancer cells and not normal tissues. KK-LC-1 belongs to a family of tumor antigens known as cancer-testis antigens, which have restricted expression in immune-privileged germ cells and various cancers, and not in normal life-essential tissues. This makes KK-LC-1 an attractive target for T-cell based anti-cancer therapies.Inventors from the National Cancer Institute ’sExperimental Transplantation and Immunology Branch (NCI ETIB) have discovered two n...

Abstract Biomedical engineering seeks to enhance the quality of life by developing advanced materials and technologies. Chitosan-based biomaterials have attracted significant attention because of having unique chemical structures with desired biocompatibility and biodegradability, which play different roles in membranes, sponges and scaffolds, along with bring about promising biological properties such as biocompatibility, biodegradability and non-toxicity. Therefore, chitosan derivatives have been widely used in a vast variety of uses, chiefly pharmaceuticals and biomedical engineering. It is attempted here to dr...

In this study has been focused on genetically modified MSCs for use in RM with an emphasis on CTSs. We highlight the basic concept of genetic modifications and also discuss recent clinical studies aspects. Recently reviewed studies show that MSC therapy with assistant gene therapy can be used in cancer therapy, heart diseases, Fanconi anemia and several other diseases.
