The Role of Exosome RNA in Cancer
The Relationship Between Exosomes and Cancer Exosomes are nanoscale vesicles derived from intracellular lysosomes that shuttle a variety of biomolecules, such as nucleic acids, proteins, lipids, amino acids and metabolites, and play a key role in regulating intercellular communication. Exosomes can be secreted by almost all types of cells, including immune cells, blood cells, neuronal cells, ...

A microRNA signature of hypoxia
Recent research has identified critical roles for microRNAs in a large number of cellular processes, including tumorigenic transformation. While significant progress has been made towards understanding the mechanisms of gene regulation by microRNAs, much less is known about factors affecting the expression of these noncoding transcripts. Here, we demonstrate for the first time a functional link ...

ADCs Customized Linkers
Antibody Drug Conjugates (ADCs) use targeting ability of monoclonal antibodies to deliver potent cytototoxic payloads to their intended target. The linker encompasses a conjugating functionality suitable for attachment to the antibody, a spacer unit that typically incorporates a hydrophilic element and a trigger which releases the potent cytototoxic warhead. The properties that an optimal linker ...

A "miracle" fruit that can enhance the immune response to tumors
The advent of immune checkpoint inhibitors (ICI) has improved the overall survival of patients with a variety of malignancies. However, the problem of drug resistance to ICI therapy remains a major obstacle limiting its clinical application. The development of drug resistance is associated with multiple factors, including the level of PD-L1 expression in tumor cells, the tumor microenvironment, ...

How Hyaluronic Acid Promotes Pancreatic Cancer Cell Growth Revealed
Hyaluronic acid is known to be present in pancreatic tumors. However, in a new study, researchers from the University of Michigan Roger Cancer Center and the University of Pennsylvania found that hyaluronic acid also acts as a food for cancer cells. The results provide new insights into how pancreatic cancer cells grow and point to new possibilities for the treatment of this cancer. The relevant ...

Modified bacteria produce tetanus toxin, which is utilized to treat fatal pancreatic cancer
Pancreatic cancer is a highly malignant tumor of the digestive tract that is difficult to diagnose and treat, and the morbidity and mortality rates have risen dramatically in recent years. Pancreatic cancer is at an advanced stage when diagnosed when cancer cells have spread and are hard to control. The most frequent pancreatic cancer is pancreatic ductal adenocarcinoma (PDAC), accounting for ...

Ozette’s computationally-driven analysis aids advancement of cancer drug development - Case study
Summary Inflammation is a hallmark of the tumor microenvironment and an area of active investigation. To better understand how tumor inflammation differs from general inflammation, such as in gum disease, Drs. Prilic, Mair, and Erikson employed novel methods, which included high parameter flow cytometry and Ozette’s foundational technology–full annotation using ...

Celdara Medical Receives National Institutes of Health Funding to develop a new CAR T cell platform to treat solid tumors
Celdara Medical, LLC today announced that the National Cancer Institute of the National Institutes of Health (NIH) has awarded a Small Business Innovation Research (SBIR) Phase I award to fund the company’s proof of concept studies on a new platform to improve chimeric antigen receptor (CAR) T cells efficacy to treat solid tumors. Dr. Joana Murad-Mabaera, who leads this effort, stated, ...

Gamma delta T cells in tumor immunotherapy
Immunotherapy, in addition to surgery, chemotherapy, and radiotherapy, has now become the fourth pillar of anticancer treatment, with T cell-based immunotherapy being a successful cancer treatment technique. T cells can be separated into two subpopulations based on the expression of T-cell receptors (TCRs). αβ T cells, expressing expressing αβ TCR, recognize peptide antigens, such as those ...

The Emergence of a New Force: Circular RNA
Circular RNAs are closed-loop single-stranded RNA (ssRNA) that are structurally specific, and produced by the back-splicing process. CircRNAs can exist independently of proteins and are unaffected by exonucleases, and are widely found in plant and animal cells to regulate gene expression. Circular RNAs were first discovered by Sanger studying virus-like RNAs. And in 1991, Nigro stumbled upon an ...

CADM: A New Generation of Tumor Suppressor Genes
About Tumor Suppressor Genes A tumor suppressor gene, also known as anti-onco gene, is an essential component of the body's defense against cancer. It usually facilitates apoptosis. With its absence, the human body will be functioning without its “brake” of cell proliferation. Cells are potent to go under abnormal growth processes and finally lead to tumor/cancer. Here are some key ...

Three generations of ADC: Nearly a decade of development-PII
Kadcyla and second-generation non-cleavable linkers Alternative linker design methodologies are still under development. Immunogen discovered a very powerful ADC by an accidental discovery. The lysine residue of trastuzumab is linked to DM1 via a non-cleavable linker containing N-succinimidyl-4-(N-maleimidomethyl)cyclohexane-1-carboxylate (SMCC), an ADC (T-DM1, Kadcyla) authorized by the FDA in ...

Mesothelin: A New Target for Cancer Therapy
Structure and function of mesothelin The MSLN gene is located in chromosome 16p13. It contains 17 exons, with a cDNA length of about 2138bp, has a 1884-bp open reading frame, and encodes the precursor protein of 628 amino acids (69 kDa). This precursor protein can be hydrolyzed by furin protease into two parts: mesothelin in the size of 40 kDa fragments and 31 kDa secreted fragments called ...

Targeting Interleukin-6 Helps to Mitigate the Side Effects of Immunotherapy
Researchers at The University of Texas MD Anderson Cancer Center have identified a new strategy to reduce immune-related adverse events by targeting immunotherapy with the cytokine interleukin-6 (IL-6). The study, published in Cancer Cell, provides evidence for the concept of combining immune checkpoint blockers and cytokine blockers to selectively inhibit inflammatory autoimmune responses. ...

Science: Knockout of this epigenetic gene gives CAR-T cells the ability to continuously attack cancer cells
Simply put, CAR-T is to transform the patient's immune T cells in vitro by biotechnology, so that they recognize antigens on the surface of tumor cells, and then inject these cells back into the patient to achieve the therapeutic effect of recognizing and killing cancer cells. In 2017, CAR-T therapy was first approved by the FDA for the treatment of blood cancers such as leukemia and lymphoma. ...

Cancer Target: Mesothelin
Mesothelin is a glycosylphosphatidylinositol (GPI)-anchored cell surface glycoprotein. Its biological function has not yet been clarified, but due to its limited distribution in normal tissues and high expression in some tumor tissues, it is expected to be used in tumor-specific treatment. In existing studies of human epidermoid carcinoma cell lines expressing mesothelin, biodistribution analysis ...

Antibody Drug Conjugates: "Biological Missiles" For Targeting Cancer Therapy
Antibody-drug conjugates (ADCs) usually consist of monoclonal antibodies (mAbs) covalently linked to cytotoxic drugs via chemical linkers. With high specific targeting ability and strong killing effect, it has achieved precise and efficient removal of cancer cells, and has become one of the hot spots in the development of anticancer drugs. In 2000, the FDA first approved the ADC drug Mylotarg ...

How to activate the "first responders" of the immune system - NK cells
About NK Cells Natural Killer (NK) cells play a critical role in the innate immune surveillance against cancer and viral infections. They are the "first responders" capable of spontaneously recognizing abnormal cells in the body, swiftly eliminating them through targeted cytotoxic mechanisms, and effectively producing pro-inflammatory cytokines and chemokines to recruit and activate other immune ...

CAR-T Cell Anti-Cancer Therapy Ushered in A Revolutionary Breakthrough!
Chimeric antigen receptor T cells (CAR-T) and T cell antigen receptor chimeric T cells (TCR-T) are currently the "top stream" in adoptive T cell tumor immunotherapy. In particular, CAR-T therapy, which has been approved by the FDA, is rewriting the treatment paradigm of some hematological tumors. However, adoptive T cell therapy remains of little success in solid tumors. The main reason is that ...
