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

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.

Common Acid Reflux Drug May Increase Stomach Cancer Risks

Acid reflux is a relatively common condition that affects a number of people worldwide. Evidence from recent studies suggests that one of the more widely-used acid reflux treatments may increase the risk of stomach cancer.

H. Pylori and Stomach Cancer

Around the globe, stomach cancer is the fifth most common cancer causing the third highest number of cancer-related deaths. H. pylori, a bacterium found in two-thirds of the world’s population, is a major cause of ulcers and a significant risk for stomach cancer.

A 2016 review revealed an association between long-term use of proton pump inhibitors (PPI), a frequently prescribed treatment for acid reflux, and increased risk of cancer. Scientists remained uncertain because the review failed to distinguish between H. pylori and H. pylori-negative participants.

Can Acid Reflux Treatment Increase Stomach Cancer Risk?

In 2017, researchers at the University of Hong Kong set out to find some clarity on the issue. The team separated the study group into PPI users and those using another acid reflux drug known as H2 blockers.

Nearly 64,000 participants began with a seven-day course of triple therapy, which involves use of a PPI with two antibiotics to eradicate H. pylori. Results showed that, even in the absence of H. pylori, PPI usage more than doubled risk of stomach cancer while usage of H2 blockers demonstrated no increased risk.

MSK1 Protein Research May Answer Why Some Breast Cancer Stays Dormant

Scientists have long been puzzled by the process of metastasis in breast cancer and what causes the cells to lie dormant. A recent study revealed valuable information that can pay off with more effective breast cancer treatment.

Understanding Latency in Breast Cancer Metastases

Researchers at the Institute for Research in Biomedicine (IRB) in Barcelona set out to study estrogen-positive (ER+) breast tumors that feature long periods of asymptomatic latency. This type accounts for 80 percent of breast cancer cases.

The Barcelona team identified a protein kinase called MSK1 as the primary regulator of dormant metastases. After examining clinical samples from patients, the researchers determined that ER+ breast cancer tumors that don’t express MSK1 tend to suffer earlier relapse, while those that do express MSK1 experience later metastases.

Breakthrough in Breast Cancer Treatment

Head researcher Roger Gormis explained that little was previously known about why breast cancer metastasis time varies from one patient to another. Study results also showed that suppressing MSK1 causes faster-growing cancer cells that have a greater chance of metastasizing.

Benefits of the study are two-fold:

– Doctors may be better able to identify patients who are more likely to relapse and adjust treatment protocol.

– Scientists may be able to develop a treatment that mimics the role of MSK1, thereby keeping metastasis dormant for as long as possible.

Early detection often makes the difference in successful cancer treatment. Thanks to a newly developed blood test, doctors will soon be able to screen for eight of the more common types of cancer.

Focusing on Early Stage Cancer Detection

CancerSEEK was developed by a team of scientists at Johns Hopkins Kimmel Cancer Center. It screens for cancers of the ovaries, liver, stomach, pancreas, colorectum, lung and breast. Collectively, these types are responsible for more than 60 percent of cancer deaths in the United States.

Based on the idea that circulating tumor DNA mutations can be specific cancer markers, the researchers set out to study several hundred genes and 40 protein markers. They finally ended up with segments of 16 genes and eight proteins, with the small mutation panel minimizing the possibility of false-positive results.

According to Nickolas Papadopoulos, senior author of the study, the team was inspired by the concept of using combinations of drugs for cancer treatment. When the test was administered to 1,005 patients with non-metastatic cancer, its median overall sensitivity to cancer was 70 percent with only seven false-positives.

The Future of CancerSEEK

Researchers are proceeding to larger studies of CancerSEEK. They project that once the test is approved for use the cost will be less than $500, and primary care providers will be able to administer the test with other routine blood work.

What options does a patient have when traditional forms of cancer treatment fail? In the case of testicular cancer, scientists found a new combination of treatments that may provide added hope.

Overcoming Resistance to Cancer Treatment

Testicular germ cell tumors are a form of cancer found most commonly in younger men. A research team at the Institute of Cancer Research in London, encouraged by earlier work at the facility, examined the function of a certain type of protein in the development of testicular cancer.

The team focused specifically on insulin growth factor receptor-1. They discovered that IGF1R, as the protein is also called, was more active in some testicular cancer cells as opposed to normal tissue. Using chemical inhibitors, the researchers were able to deplete the supply of IGF1R or curtail its activity, thereby reducing cell growth.

In addition, blocking IGF1R activity in previously drug-resistant cells made them more receptive to platinum-based chemotherapy. The team is hopeful that the two treatments, used in tandem, will be more successful in killing testicular cancer cells.

What Does the Future Hold?

Receptor tyrosine kinases, the class of proteins that includes IGF1R, are linked to cell growth and division in several other types of cancer. Clinical trials have tested the use of IGF1R in hopes that they may have positive results in other applications.
