Honing in on shared network of cancer genes
24. Dezember 2021
Using network modeling, researchers have honed in on a set of gene interactions that are critical to malignancy and likely to be fertile ground for broad cancer therapies.
Pioneering new technique to barcode cells

Scientists have developed a pioneering new technique to barcode individual cells more accurately and efficiently – which could help pave the way for quicker disease diagnosis.
Research breakthrough could see HIV drugs used to treat low-grade brain tumors
20. Dezember 2021
Drugs developed to treat AIDS and HIV could offer hope to patients diagnosed with the most common form of primary brain tumor. The breakthrough is significant because, if further research is conclusive, the anti-retroviral drugs could be prescribed for patients diagnosed with meningioma and acoustic neuroma brain tumors (also known as schwannoma).
Nanoparticle therapeutic enhances cancer immunotherapy
20. Dezember 2021
Researchers have discovered that a nanoparticle therapeutic enhances cancer immunotherapy and is a possible new approach in treating malignant pleural effusion (MPE). MPE is the accumulation of fluid between the chest wall and lungs and is accompanied by malignant cells and/or tumors.
New potential treatment for graft-versus-host-disease and other inflammatory disorders
20. Dezember 2021
Researchers have shown that blocking IL-6 and TNF cytokines provides a more effective approach to preventing life-threatening graft-versus-host-disease, an inflammatory condition that develops in patients after their allogeneic hematopoietic stem cell transplantation.
Reducing copper in the body alters cancer metabolism to reduce risk of aggressive breast cancer
17. Dezember 2021
Depleting copper levels may reduce the production of energy that cancer cells need to travel and establish themselves in other parts of the body by a process referred to as metastasis, according to a new study. The discovery of the underlying mechanisms of how copper depletion may help reduce metastasis in breast cancer will help inform the design of future clinical trials.
Immune system responds to mRNA treatment for cancer, researchers find
17. Dezember 2021
Adding messenger RNA, or mRNA therapy improves the response to cancer immunotherapy in patients who weren’t responding to the treatment, new research shows. Immunotherapy uses the body’s immune system to prevent, control and eliminate cancer.
For children, young adults with recurrent AML, immunotherapy shows promise
15. Dezember 2021
Researchers have shown, in a small clinical trial, that an immunotherapy harnessing pre-activated natural killer cells can help some children and young adults with recurrent AML and few other treatment options.
Improving drug options for colorectal cancer patients
15. Dezember 2021
Patients with colorectal cancer were among the first to receive targeted therapies. These drugs aim to block the cancer-causing proteins that trigger out-of-control cell growth while sparing healthy tissues. But some patients are not eligible for these treatments because they have cancer-promoting mutations that are believed to cause resistance to these drugs. Now, physician-scientists have used computer modeling and cell studies to discover that more patients may be helped by a common class of targeted therapies than previously thought.
Boosting anti-cancer action by driving up immunity at tumor site
15. Dezember 2021
Driving up the immune response at the site of a cancer tumor with nanotechnology may help enhance immunotherapy treatments in advanced stages of the disease, new research in mice suggests.
Cancer-spotting AI and human experts can be fooled by image-tampering attacks
15. Dezember 2021
Artificial intelligence (AI) models that evaluate medical images have potential to speed up and improve accuracy of cancer diagnoses, but they may also be vulnerable to cyberattacks. Researchers simulated an attack that falsified mammogram images, fooling both an AI breast cancer diagnosis model and human breast imaging radiologist experts.
Gene Network changes associated with cancer onset and progression identify new candidates for targeted gene therapy
15. Dezember 2021
Researchers have identified novel changes in gene network interactions associated with cancer that may lead to new treatment targets for chemotherapy. Their work shows that more than 90% of changes in gene network interactions in nine types of cancer studied are not detectable by current tests focused on changes in gene expression.
‚Supermeres‘ may carry clues to cancer, Alzheimer’s disease and COVID-19
14. Dezember 2021
Researchers have discovered a nanoparticle released from cells, called a ’supermere,‘ which contains enzymes, proteins and RNA associated with multiple cancers, cardiovascular disease, Alzheimer’s disease and even COVID-19.
Research demonstrates that cells with cancer-associated mutations overtake human tissue with age
14. Dezember 2021
Recently published research has found that most cancer-free individuals over age 60 carry at least 100 billion cells harboring at least one oncogenic, or tumor-causing, mutation.
Cannabis use could cause harmful drug interactions
14. Dezember 2021
Using cannabis alongside other drugs may come with a significant risk of harmful drug-drug interactions, new research suggests. The researchers looked at cannabinoids–a group of substances found in the cannabis plant — and their major metabolites found in cannabis users‘ blood and found that they interfere with two families of enzymes that help metabolize a wide range of drugs prescribed for a variety of conditions. As a result, either the drugs‘ positive effects might decrease or their negative effects might increase with too much building up in the body, causing unintended side effects such as toxicity or accidental overdose. While more research needs to be done, the authors said one early takeaway from these studies is that it’s important to be careful when using cannabis with other prescription drugs.
Scientists identify malfunctioning brain cells as potential target for Alzheimer’s treatment
11. Dezember 2021

Research reveals how aging cells can be an underlying cause of kidney damage
9. Dezember 2021
A study in mice has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and permanently stops dividing but does not die. Importantly, when the researchers eliminated senescent cells from the mice, tissues returned to a normal state in spite of a continued infusion of angiotensin II.
