Scientists have engineered small, targeted proteins that can penetrate brain cancer cells and prevent them from invading healthy tissue, offering a promising new approach to treating glioblastoma multiforme (GBM), one of the deadliest forms of brain cancer. This strategy was developed by researchers at the University of Nevada, Reno, and published recently in Oncotarget.

The Challenge of Treating Glioblastoma Multiforme

Glioblastoma is an aggressive and fast-growing brain tumor that infiltrates healthy brain tissue, making complete surgical removal nearly impossible. Standard treatments like chemotherapy and radiation can slow its growth but rarely prevent it from returning. One major reason for this invasiveness is a group of enzymes known as matrix metalloproteinases (MMPs), which break down surrounding tissue to allow cancer cells to spread. Among these, MMP-9 plays a particularly important role in driving tumor progression and resisting existing therapies.

Attempts to block MMPs using small-molecule drugs have failed in clinical trials due to problems like poor selectivity and harmful side effects. Researchers have been searching for safer, more targeted methods to interfere with these enzymes and limit glioblastoma’s spread.

The Study: Engineered Proteins to Inhibit Tumor Invasion

In the study called “Effect of TIMPs and their minimally engineered variants in blocking invasion and migration of brain cancer cells,” researchers Elham Taheri and Maryam Raeeszadeh-Sarmazdeh investigated tissue inhibitors of metalloproteinases (TIMPs), which are natural blockers of MMPs, and their engineered modified versions made to work better. Specifically, the team studied TIMP-1, TIMP-3, along with two engineered molecules, mTC1 and mTC3, in laboratory cell models of GBM.

Engineered Proteins Show Promise in Stopping Glioblastoma Invasion

BUFFALO, NY - May 23, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on May 19, 2025, titled “Immune-mediated adverse events following atezolizumab and bevacizumab in a multinational Latin American cohort of unresectable hepatocellular carcinoma."

The study, led by first authors Leonardo Gomes da Fonseca from Hospital das Clínicas, Universidade de São Paulo, Brazil, and Federico Piñero from Hospital Universitario Austral, Argentina, investigated how patients with advanced liver cancer in Latin America respond to a widely used immunotherapy combination. The researchers found that although a minority of patients developed immune-related side effects, these events did not significantly impact overall survival. Their findings highlight the importance of early recognition and careful management of such side effects in real-world clinical settings.

Liver cancer is a leading cause of cancer deaths worldwide, with limited treatment options for patients diagnosed at an advanced stage. Immunotherapy, particularly the combination of atezolizumab and bevacizumab, has become a standard approach. However, these treatments can sometimes trigger the body’s immune system to attack healthy organs, leading to what are called immune-related adverse events, or irAEs. Until now, little data existed on how frequently these events occur in Latin American patients and whether they impact treatment outcomes.

The researchers followed 99 patients from Argentina, Brazil, Chile, and Colombia, most of whom had cirrhosis or underlying liver disease. They received atezolizumab and bevacizumab for a median duration of six months. The researchers reported that only 18% of the patients experienced immune-related side effects, most commonly affecting the liver (hepatitis) and thyroid (thyroiditis). Most of these cases were mild or moderate, and half of them resolved completely within a month. Only eight patients needed treatment with steroids to control the immune response.

Importantly, the occurrence of immune-related side effects did not affect how long patients survived after starting treatment. The median survival was the same—18.5 months—for both those who experienced irAEs and those who did not. This result suggests that while irAEs require careful management, they may not reduce the overall benefits of immunotherapy.

Another significant finding was that patients with higher levels of alpha-fetoprotein (AFP), a protein often elevated in liver cancer, were more likely to experience these side effects. This information could help clinicians identify patients who need closer control during treatment.

“Notably, baseline alpha-fetoprotein (AFP) values ≥400 ng/ml were significantly associated with the development of irAEs.”

The study also points to key differences between clinical trial results and real-world experiences. While clinical trials report higher rates of side effects, this real-world data showed a lower incidence, possibly due to less intensive monitoring or differences in how side effects are documented in everyday practice.

In summary, this study highlights that patients require ongoing vigilance and individualized care when treating liver cancer with immunotherapy. It provides valuable information to healthcare providers in Latin America and other regions with similar patient populations, aiming to improve outcomes while minimizing risks.

Building Effective AI Foundation Models at Standard Model Biomedicine With Kevin Brown and Waqas Haque, MD, MPH

Researchers at Brown University have developed a combination treatment that significantly increases survival in mice with glioblastoma (GBM), a highly aggressive and treatment-resistant brain cancer. The approach uses a new class of drugs called imipridones along with radiation therapy and standard chemotherapy. This triple therapy, known as IRT, was recently detailed in a study published in Oncotarget.

Understanding Glioblastoma and the Need for Better Therapies

Glioblastoma is the most common and aggressive malignant brain tumor in adults. It grows quickly and is difficult to treat, often leading to poor outcomes. Most patients survive less than 15 months after diagnosis, even when treated with surgery, radiation, and the chemotherapy drug temozolomide (TMZ). This treatment may slow the disease, but it does not typically stop it.

Rising Cancer Rates in Younger Adults with Mohit Manrao from AstraZeneca

BUFFALO, NY – June 9, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on May 20, 2025, titled “Cigarette smoke and decreased DNA repair by Xeroderma Pigmentosum Group C use a double hit mechanism for epithelial cell lung carcinogenesis.”

In this study, led by first author Nawar Al Nasralla and corresponding author Catherine R. Sears, from the Division of Pulmonary, Critical Care, Sleep and Occupational Medicine, Indianapolis and the Richard L. Roudebush Veterans Affairs Medical Center, researchers investigated how cigarette smoke and reduced DNA repair capacity contribute together to the development of lung cancer. They found that when a critical DNA repair protein called XPC is decreased and lung cells are exposed to cigarette smoke, the combination causes extensive damage and significantly increases cancer risk.

Non-small cell lung cancer (NSCLC) develops through both genetic and environmental factors. This study focused on how cigarette smoke affects the body’s natural ability to repair DNA. The researchers studied the role of XPC, a protein essential for recognizing and repairing harmful DNA changes caused by tobacco smoke. They found that low levels of XPC — commonly seen in lung cancer patients — made lung cells less capable of repairing DNA. This made the cells unstable and more likely to become cancerous. These changes were most pronounced in normal lung cells, suggesting that the earliest stages of disease occur before cancer is even detected.

The findings support a “double hit” model, where both cigarette smoke and reduced DNA repair work together to drive cancer development. In laboratory experiments, normal lung cells with low XPC levels showed more damage and cell death after cigarette smoke exposure. By contrast, lung cancer cells were more resistant to smoke damage, even when XPC was low, indicating that critical changes had likely occurred earlier in the disease process.

“Our study suggests that cigarette smoke exposure leads to decreased XPC mRNA expression, exacerbates total and oxidative DNA damage, hinders NER, and may contribute to lung cancer development.”

The study also showed that DNA repair ability declined significantly in healthy cells after smoke exposure, but this effect was not seen in cancer cells. In addition, the researchers confirmed that XPC gene activity was lower in actual lung tumor tissue compared to nearby healthy lung tissue. This pattern was consistent across both adenocarcinoma and squamous cell carcinoma, the two main types of NSCLC.

These results add to our understanding of how lung cancer begins at the molecular level. By showing how cigarette smoke and reduced DNA repair combine to create genetic instability, the research points toward new strategies for prevention. A better understanding of XPC’s role could help identify high-risk individuals and inform future efforts to stop lung cancer before it begins.

Oncotarget Sponsors Open Access Team in 2025 Ride for Roswell

BUFFALO, NY - June 13, 2025 – A new #review was #published in Volume 16 of Oncotarget on June 4, 2025, titled “Applying the unattainable triangle in cardio-oncology care: Balancing cost, quality, and time.”

In this review, first author John Hoverson, corresponding author Stella Pak, and colleagues from the University of Texas Health Science Center at San Antonio explore how the “unattainable triangle”—a business concept describing the trade-offs between cost, quality, and time—can help improve healthcare delivery in cardio-oncology. As cancer treatments become more complex and often affect the heart, this model highlights the challenge of providing care that is fast, effective, and affordable.

Cardio-oncology is an emerging field focused on preventing and managing heart problems caused by cancer therapies. The review explains that high-quality cancer care often requires advanced diagnostics and close collaboration between oncologists and cardiologists, which can drive up costs and time demands. Understanding how to balance these pressures is essential for delivering better outcomes for patients.

Many cancer survivors face long-term cardiovascular complications due to their treatment. Early monitoring and intervention can reduce these risks. However, these improvements often come with financial burdens, especially when key tests are not covered by insurance. Meanwhile, both patients and clinicians must manage the burden of tight appointment schedules, long clinic visits, and increasing demands on their time.

To improve care quality, the authors emphasize the need for interdisciplinary teamwork and ongoing education. Surveys show that many clinicians are still unfamiliar with cardio-oncology guidelines, which can compromise care. The review also highlights the potential for artificial intelligence and digital tools to streamline care delivery, reduce wait times, and support both patients and providers.

Importantly, the authors point out that improving one area—such as quality—can come at the expense of others, like cost or time. They encourage healthcare systems to take a balanced approach, setting clear goals and using integrated care models that consider all three elements of the triangle together.

“While a perfect model for managing the unattainable triangle may be simply that, ‘unattainable’, investments in research, patient-centered care, data-driven decision-making, and financial alignment with payers will be crucial to the long-term success of both patient outcomes and the organization’s profitability.”

While achieving perfect balance may be difficult, the review suggests that using the unattainable triangle as a guiding framework can help hospitals and clinicians make smarter, more sustainable decisions. As cardio-oncology continues to expand in response to the growing number of cancer survivors with cardiovascular needs, this approach could help improve patient outcomes and strengthen healthcare systems.
