New pancreatic cancer treatment proves effective in shrinking, clearing tumors
August 28, 2024 by University of Massachusetts Amherst Researchers at the University of Massachusetts Amherst and UMass Chan Medical School have demonstrated in mice a new method to combat pancreatic cancer. The study, published in Science Translational Medicine, outlines the synergistic effects of a novel nanoparticle drug-delivery system to activate an immune pathway in combination...
Lung cancer treatment shows promise in tumor models

DOI: 10.1038/s41467-024-44861-8A molecule has demonstrated its ability to kill tumor cells and incite an immune response in preclinical models of small cell lung cancer (SCLC), according to UT Southwestern Medical Center researchers. The findings, published in...
Magnetic Bacteria Target Tumors
CONN HASTINGS MEDICINE, NANOMEDICINE, ONCOLOGY Scientists at ETH Zurich in Switzerland have unveiled a technique that weaponizes bacterial cells against tumors. The approach involves using bacteria called Magnetospirillum that are naturally magnetic by virtue of the iron oxide particles they contain. The researchers use a rotating magnetic field applied at the tumor location from outside...
Making Tumors Tastier for the Immune System
CONN HASTINGS MEDICINE, NANOMEDICINE, ONCOLOGY Researchers at The University of Texas MD Anderson Cancer Center have developed a nanotechnology platform that can make cancer cells more vulnerable to immune attack in the body. The researchers call their system the bispecific tumor-transforming nanoconjugate (BiTN) platform. The idea is to make solid tumors more appealing for the...
Scientists identify cancer kill ‘switch’ that destroys tumours from the inside out
US researchers spotted a ‘switch’ that causes cancer cells to self-destructThe team now hopes to develop a treatment that targets this part of the cellBy EMILY CRAIG DEPUTY HEALTH EDITOR FOR MAILONLINE PUBLISHED: 05:45 EDT, 25 October 2023 | UPDATED: 05:45 EDT, 25 October 2023 A kill ‘switch’ which triggers the death of cancer cells...
Blood test detects tumors early in families with Li-Fraumeni syndrome
by The Hospital for Sick Children Credit: CC0 Public DomainResearchers from The Hospital for Sick Children (SickKids), the Ontario Institute for Cancer Research (OICR) and University Health Network (UHN) have demonstrated that by analyzing patients’ blood samples, they are able to detect cancer earlier in individuals with Li-Fraumeni syndrome, an inherited condition with an almost 100%...

Microbubble macrophages track tumors
by Acoustical Society of America Attaching microbubbles to macrophages can create high-resolution and sensitive tracking images useful for disease diagnosis. Credit: Ashley Alva Macrophages, a type of white blood cell, defend the body by engulfing and digesting foreign particles, such as bacteria, viruses, and dead cells. The immune cells also tend to accumulate in solid...
