According to a popular old wives’ tale, you should starve a cold and feed a fever. Scientists working on immunotherapy for cancer are taking that advice a step further as they develop a new treatment that “starves” tumors to death.

Cutting Off Cancer’s Fuel Source

Glutamine is an amino acid found throughout the body, with the largest concentrations in blood and bone. While glutamine plays a major role in cellular synthesis of proteins, it also provides fuel for the rapid cell division of many types of cancer.

A research team at Vanderbilt University in Nashville began exploring the idea of blocking glutamine from cancer cells as a possible form of treatment. They focused on ASCT2, a protein that transports glutamine to cancer cells as well as other parts of the body.

The scientists created an ASCT2 inhibitor called V-9302. In testing on both mice and cancer cells developed in vitro, V-9302 was able to stop tumor growth by increasing oxidative stress on cancer cells, leaving them to eventually die off.

Using PET Imaging to Trace Tumors

As the team noted in their report, the next step is to find a way to determine how effective the inhibitors are in restricting glutamine access. The researchers suggested using positron emission tomagraphy (PET) scans to spot increases in glutamine metabolic rates.

Will CRISPR Gene Editing Play a New Role in Cancer Treatment?

New Research Is Unlocking the Mystery of Cancer
New Research Is Unlocking the Mystery of Cancer

As science makes connections between DNA mutations and cancer, gene-targeted therapies have become a valuable way to make cancer treatment more effective. Now researchers are pondering how advanced genome editing technology might impact the future of cancer research and treatment.

Solving the Puzzle of DNA

All biological lifeforms are composed of three primary substances. DNA, the building block of genes, uses RNA as a messenger to control proteins, which are the cellular “worker bees.” RNA and proteins can be targeted with drugs, medicines and other treatments, but DNA is more complicated.

CRISPR is a process that lets scientists actually manipulate and make changes to genetic material in cells. In theory, CRISPR could be used to “edit” diseases such as cancer right out of patients.

Can Genetic Editing Improve Cancer Treatment?

Finding the precise genes that drive cancer development can be like looking for a needle in a haystack. With the help of CRISPR, researchers can replace normal genes with cancer-causing ones to get a better picture of how the mutations work and thereby create more effective treatment solutions.

According to Dr. Irene Chong, a clinical scientist at the Institute of Cancer Research in London, the precision of CRISPR holds possible ramifications for future cancer treatment. Doctors may eventually be able to target and correct genetic mutations that cause a predisposition to cancer.

Personalized Dendritic Cell Vaccines As Effective Immunotherapy Make the News

One of the benefits of immunotherapy for cancer is that treatments can often be tailored to address a patient’s individual needs. Scientists in Switzerland have now developed a method of modifying dendritic cell vaccines that makes them easier to personalize.

Aiding the Body’s Own Immune Response

Dendritic cell vaccines are normally created by force-feeding dendritic cells with tumor antigens. Scientists at the Swiss Institute for Experimental Cancer Research have developed a modification that allows dendritic cells to acquire antigens from a patient’s tumor.

Prof. Michele De Palma, winner of the 2017 Swiss Cancer League award, led the team of researchers in creating an extracellular vesicle (EV)-internalizing receptor, referred to as EVIR. The EVIR has been optimized to enhance dendritic cells and their ability to selectively uptake cancer cell-derived EVs.

Antigen-laden exosomes and other extracellular vesicles are released by tumors in sizable quantities. The EVIR helps dendritic cells target the exosomes more precisely and present them to killer T-cells for a more efficient immune response.

Streamlining the Job of Dendritic Cells

De Palma explained the phenomenon of cross-dressing, in which dendritic cells display the acquired antigens directly on their surface. The process simplifies the immune response by eliminating the need for more complex interactions within the dendritic cell itself.

Properties of Breast Tissue May Play a Role in Cancer Progression

There is New Hope for Breast Cancer Treatment
There is New Hope for Breast Cancer Treatment

Doctors have found some success with immunotherapy for cancer during the late stages of the disease, but the mystery of what causes certain tumors to spread has remained unsolved. Scientists are now turning to a surprising source for information about breast cancer progression.

A Matter of Engineering?

Ovijit Chaudhuri, an assistant professor of mechanical engineering, has been working with researchers across campus exploring the mechanical properties of breast tissue and their role in cancer progression. According to Chaudhuri, evidence supporting this relationship has been accumulating over the last 20 years.

Questions being studied by the teams include:

– How does stiffness of breast tissue encourage the growth and spread of tumors? Chaudhuri’s group is culturing mammary cells inside a hydrogel and tuning its stiffness to determine how it affects the development of cancer cells.

– How do cancer cells find their way past the membrane surrounding breast tissue that is seemingly too dense to allow passage? Currently, the scientists theorize that the cells use a combination of enzymes and force to “cut” their way through.

– As surrounding tissue grows in stiffness over time, how do tumors find space to expand?

Mechanobiology: A Complementary Approach

This isn’t the first time that scientists have sought biological information from the field of engineering. The result is the hybrid science of mechanobiology, which studies the interactions of mechanical properties and biological processes.

One Important Step to Improving Treatment for Therapy-Resistant Cancers

Cancer Therapies at the Molecular Level in Intracellular Proteins
Cancer Therapies at the Molecular Level in Experimental Antibodies

The use of immunotherapy for cancer has helped many patients with cancers that are difficult to treat or cancers that have spread. However, there have been certain limits on how this treatment works. In some cases, tumors have become resistant to this form of treatment. Researchers have been working on a combination therapeutic approach that shows more promise in effectively fighting cancer.

Experimental Antibody

Researchers at Stanford and Yale developed an experimental antibody that is able to target more immune cells that are involved with the growth of tumors. Current immunotherapy approaches focus on a smaller number of these immune cells, which limits their ability to eliminate cancerous tumors. While these approaches have stopped cancer from spreading in some cases, they have been unable to successfully deal with tumor growth in other cases.

The experimental antibody is able to prevent another type of immune cell, known as a myeloid cell, from contributing to tumor growth and immunotherapy drug resistance.

Combination Immunotherapy

The use of this experimental antibody along with immunotherapy drugs is showing the potential for effectively fighting cancer. Researchers have used it on cell culture models and mouse models that contain human cell membrane proteins. This combination immunotherapy approach limits the growth of tumor cells, making it harder for them to thrive and spread. Researchers still need to do more studies on this experimental antibody in order to determine if it can be used to treat cancer cases that are metastatic or more advanced.

One of the benefits of immunotherapy for cancer is that these treatments often have positive results where others have failed. Results of two recent studies show that immunotherapy has real possibilities for treating multiple myeloma.

What Is Multiple Myeloma?

Multiple myeloma is the second-most diagnosed form of blood cancer, just behind non-Hodgkin’s lymphoma. In patients with multiple myeloma, infection-fighting plasma cells grow out of control, causing bone tumors and chronic infections.

Immunotherapy for Cancer: A Promising Treatment for Multiple Myeloma?

In 2017, a research team from Abramson Cancer Center at the University of Pennsylvania conducted two separate studies involving patients with multiple myeloma that had proven resistant to other therapies.

Patients in the first study received a single dose of chemotherapy before being infused with CART-BCMA, a specific form of chimeric antigen receptor (CAR) T-cell therapy developed by Penn researchers in collaboration with Novartis. Results indicated that 64 percent of the group had a positive response.

In the second study, sponsored by GlaxoSmithKline, patients received an experimental monoclonal antibody known as GSK2857916. The drug specifically targets delivery of a chemotherapy drug directly to cancer cells. Overall response rate was 60 percent, with more than half the responding patients experiencing a greater than 90 percent reduction in myeloma protein levels.

Both treatments target BCMA, which is a protein expressed by multiple myeloma cells.
