“We suggest that future therapeutic strategies targeting the oncogenic network of CDK4/6, MEK, PD-L1, and FOXM1 represent exciting future treatment options for MPNST patients.”
BUFFALO, NY- October 1, 2024 – A new mini review was published in Oncotarget's Volume 15 on September 30, 2024, entitled, “Linking FOXM1 and PD-L1 to CDK4/6-MEK targeted therapy resistance in malignant peripheral nerve sheath tumors.”
As highlighted in the abstract of this paper, malignant peripheral nerve sheath tumors (MPNSTs) are aggressive, Ras-driven sarcomas characterized by the loss of the NF1 tumor suppressor gene and the hyperactivation of MEK and CDK4/6 kinases. Currently, MPNSTs lack effective therapies. Recently, the authors demonstrated the remarkable efficacy of dual CDK4/6-MEK inhibition in mice with de novo MPNSTs, which was further enhanced by targeting the immune checkpoint protein PD-L1. This triple combination therapy, targeting CDK4/6, MEK, and PD-L1, resulted in prolonged MPNST regression and improved survival, although most tumors eventually developed drug resistance.
In their latest mini review, researchers Joshua J. Lingo, Ellen Voigt, and Dawn E. Quelle from the University of Iowa’s Cancer Biology Graduate Program, Holden Comprehensive Cancer Center, Medical Scientist Training Program, Department of Neuroscience and Pharmacology, and Department of Pathology, explore the immune activation phenotype caused by CDK4/6-MEK inhibition in MPNSTs, emphasizing the unique involvement of intratumoral plasma cell accumulation. They also discuss how PD-L1 and FOXM1, a tumor-promoting transcription factor, are functionally linked and may serve as key mediators of resistance to CDK4/6-MEK targeted therapies.
“We suggest that future therapeutic strategies targeting the oncogenic network of CDK4/6, MEK, PD-L1, and FOXM1 represent exciting future treatment options for MPNST patients.”

Researchers at McMaster University have identified a new therapeutic approach to preventing cancer from spreading to the brain.
In a new study, published recently in the journal Cell Reports Medicine, researchers Sheila Singh and Jakob Magolan discovered a critical vulnerability in metastatic brain cancer, which they say can be exploited with new drugs to prevent spread.
Singh, a professor in McMaster’s Department of Surgery and director of the Centre for Discovery in Cancer Research, says brain metastases are becoming increasingly prevalent and are extremely fatal, with 90 per cent of patients dying within one ...

WASHINGTON, October 1, 2024 – Too warm with a jacket on but too cold without it? Athletic apparel brands boast temperature-controlling fabrics that adapt to every climate with lightweight but warm products. Yet, consider a fabric that you can adjust to fit your specific temperature needs.
Inspired by the dynamic color-changing properties of squid skin, researchers from the University of California, Irvine developed a method to manufacture a heat-adjusting material that is breathable and washable and can be integrated into flexible fabric. They published their ...

WASHINGTON, Oct. 1, 2024 – Nuclear fission reactors act as a key power source for many parts of the world and worldwide power capacity is expected to nearly double by 2050. One issue, however, is the difficulty of discerning whether a nuclear reactor is being used to also create material for nuclear weapons. Capturing and analyzing antimatter particles has shown promise for monitoring what specific reactor operations are occurring, even from hundreds of miles away.
In AIP Advances, by AIP Publishing, researchers from the University of Sheffield and the University of Hawaii developed ...

In neuroscience and biomedical engineering, accurately modeling the complex movements of the human hand has long been a significant challenge. Current models often struggle to capture the intricate interplay between the brain's motor commands and the physical actions of muscles and tendons. This gap not only hinders scientific progress but also limits the development of effective neuroprosthetics aimed at restoring hand function for those with limb loss or paralysis.
EPFL professor Alexander Mathis and his team have developed an AI-driven approach that ...

Patients who receive umbilical cord blood transplants for blood cancers now live equally long regardless of their race, new research from UVA Cancer Center shows.
The findings, from UVA Health’s Karen Ballen, MD, and collaborators, suggests that a previously identified survival gap for Black recipients has closed and that overall survival for all recipients has increased.
The retrospective analysis looked at more than 2,600 adults and children with blood cancers who received cord blood between 2007 and 2017 ...

DALLAS, Oct. 1, 2024 – Strokes can strike at any age, challenging survivors to overcome physical, emotional and cognitive changes. Nominations are open now for the 2025 Stroke Hero Awards from the American Stroke Association, a division of the American Heart Association, which is celebrating a century of lifesaving impact this year. The awards recognize stroke survivors, caregivers, advocates and experts making a difference in the stroke community.
Every 40 seconds someone in the U.S. has a stroke[1], according to the American Heart Association’s 2024 Heart Disease and Stroke Statistical Update. Nearly 1 in 4 stroke survivors face the ...

Seven years after actor Alyssa Milano’s tweet launched the #MeToo movement into the global consciousness, attitudes towards sexual harassment and assault have shifted in many countries. A new study shows that the movement’s impact doesn’t stop there.
INSEAD professors Frédéric Godart and David Dubois, alongside Clément Bellet of Erasmus University Rotterdam, found that #MeToo triggered far-reaching changes in consumer behaviour. Sales of stereotypically feminine shoes like high heels dropped significantly weeks after the #MeToo movement swept the media ...

INDIANAPOLIS – The pandemic has highlighted the acute shortage of nurses and nursing assistants needed to care for the growing number of older adults in long-term care facilities. Yet getting nursing students excited, engaged and feeling competent to take on the challenges of caring for nursing home patients has proved elusive.
To address this critical workforce gap, researchers from Regenstrief Institute and the Indiana University School of Medicine have developed and tested an innovative curriculum for nursing students, exposing ...

The first-ever nationwide study into how Australians use and dispose of clothing has revealed people are buying too many clothes and are unsure how to discard them responsibly.
Conducted by RMIT University and commissioned by the Kmart Group and the Queensland Government, a study of 3,080 Australians explored how they acquired, used and disposed of their clothing.
Australians are among the world’s biggest clothing consumers, importing 1.4 billion units or over 383,000 tonnes annually.
But each year, more than 200,000 tonnes of clothing is sent to landfill.
The authors recommend establishing a national textile collection program for unwearable clothing that ...

Scientists need fine spatial and temporal resolution land surface temperature (LST) data for many types of research and applications. Spatio-temporal fusion, a technique that combines data from multiple sources to create high-resolution images with both spatial (space) and temporal (time) details, is an important solution for researchers needing fine spatio-temporal resolution LST data. A team of researchers propose a new spatio-temporal fusion method based on Restormer (RES-STF).
Their work is published in the Journal of Remote Sensing on August 21, 2024.
LST data, the measurement ...
