AI opens door to safe, effective new antibiotics to combat resistant bacteria
- Details
- Category: Research
In a hopeful sign for demand for more safe, effective antibiotics for humans, researchers at The University of Texas at Austin have leveraged artificial intelligence (AI) to develop a new drug that already is showing promise in animal trials.
Publishing their results in Nature Biomedical Engineering, the scientists describe using a large language model - an AI tool like the one that powers ChatGPT - to engineer a version of a bacteria-killing drug that was previously toxic in humans, so that it would be safe to use.
Drug-chemo combo increases cancer treatment efficacy
- Details
- Category: Research
A new study from the University of Michigan Health Rogel Cancer Center finds that giving a fatty acid inhibitor alongside chemotherapy could improve the treatment efficacy for patients with brain metastases from triple negative breast cancer. The findings appear in npj Breast Cancer.
Previous work has shown that the brain microenvironment has very limited lipids available for cancer cells, making it critical for cancer cells to generate their own lipids to survive.
New drug candidate blocks resistance to cancer therapies
- Details
- Category: Research
A team of researchers at the University of Michigan Health Rogel Cancer Center has designed a molecule that impairs signaling mediated by two key drivers of cancer therapy resistance. The design and preclinical evaluation of the inhibitor, MTX-531 was published in Nature Cancer.
Researchers, led by Judith Sebolt-Leopold, Ph.D., discovered MTX-531, a kinase inhibitor with the ability to selectively block both epidermal growth factor receptor (EGFR) and phosphatidylinositol 3-OH kinase (PI3K).
A new therapeutic target offers a promising pathway for multiple sclerosis treatment
- Details
- Category: Research
Researchers from Kyushu University have identified a potential therapeutic target for the treatment of advanced multiple sclerosis (MS), a potentially disabling condition associated with the central nervous system. In their latest study, conducted using an experimental mouse model of MS, they explored the role of connexin 43 (Cx43), a protein involved in cellular communication and cardiac function, and examined whether targeting this protein with specific blockers could improve MS symptoms.
Chinese medicinal fungus shows promise in treating idiopathic pulmonary fibrosis
- Details
- Category: Research
A recent study from China has reported that Cordyceps sinensis (CS), a traditional Chinese medicinal fungus, can ameliorate idiopathic pulmonary fibrosis (IPF) in mice by inhibiting mitochondrion-mediated oxidative stress. The research, conducted by a team led by Huan Tang and Jigang Wang from the Institute of Chinese Materia Medica at the China Academy of Chinese Medical Sciences, was published in Wiley's MedComm-Future Medicine.
Data from largest clinical trial of pre-symptomatic Alzheimer's disease now widely available
- Details
- Category: Research
Data from the Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) study, the first and largest clinical trial of pre-symptomatic Alzheimer's disease, is now widely available to researchers studying the condition. The comprehensive dataset has already yielded key insights about Alzheimer’s disease, which affects nearly seven million people in the United States, and sharing the data opens avenues for further progress.
Fighting antibiotic resistance with peptide cocktails
- Details
- Category: Research
Antibiotics are crucial in modern medicine, but their widespread use has led to antibiotic-resistant bacteria, posing a serious public health threat. A new study highlights the potential of random antimicrobial peptide mixtures to significantly reduce the risk of resistance evolution compared to single peptides. These findings support the development of new antimicrobial strategies, emphasizing the need for innovative solutions to outpace bacterial resistance and safeguard public health.
