Small-molecule antiviral drug targets ACE2 receptor to block coronaviruses from entering c
The ongoing evolution of SARS-CoV-2, particularly the rapid emergence of the omicron variant and its sublineages, has weakened the effectiveness of existing vaccines and antiviral drugs, underscoring the potential risk of future coronavirus pandemics. In response, a joint researc
Opposing protein pathways steer skin stem cells toward renewal or repair
Two proteins with opposing functions orchestrate the development and maintenance of healthy skin, Stanford Medicine researchers have found. Modulating their activity with topical drugs could reduce inflammation, aid wound healing and slow or halt the growth of skin cancer, the re

Nanotech platform combining paclitaxel with siRNA boosts immune response against lung canc
Researchers at the University of Arizona R. Ken Coit College of Pharmacy have developed a new strategy that helps the immune system recognize and attack lung cancer tumors more effectively. By packaging a chemotherapy drug and an RNA molecule in a tiny lipid carrier, the team boo
New drug candidate shows promise in overcoming chemotherapy resistance in small cell lung
A research team led by Prof. Liu Qingsong at the Institute of Health and Medical Technology, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has discovered a new drug candidate that may help overcome chemotherapy resistance in small cell lung cancer (S

Existing drugs could be repurposed for longevity by tapping network of aging-related genes
The quest to prolong life has gone on for as long as human existence itself, from the mythical Fountain of Youth to quick-fix fads like intermittent fasting, supplements and injections. But if you take a look in your medicine cabinet, you may unwittingly come across a drug that h

New Alzheimer's drugs offer hope for some, but good dementia care protects the humanity of
Disease-modifying drugs for Alzheimer's offer a meaningful glimpse of hope for many people who fear dementia. Alzheimer's disease is the most common cause of dementia, but dementia itself is an umbrella term for symptoms such as memory loss, confusion and changes in thinking.
Cancer drug shortage renews calls for federal action
Cancer drug shortage renews calls for federal action
Cancer doctors across the United States are running short of essential generic chemotherapy drugs, and some fear the squeeze could force widespread rationing, The New York Times reported.
Researchers discover a cause of neuron excitability in ALS, suggesting a new potential tre
Researchers discover a cause of neuron excitability in ALS, suggesting a new potential tre
Digging deep into the molecular mechanisms behind ALS, researchers at the Les Turner ALS Center at Northwestern Medicine have discovered why nerve cells overfire in the disease. Not only that—they have also designed a new drug to stop this overfiring, which could potentially slow
Scientists uncover how ovarian cancer resists chemotherapy—and how to reverse it
Scientists uncover how ovarian cancer resists chemotherapy—and how to reverse it
Michigan State University researchers have identified how ovarian cancer cells become resistant to chemotherapy and discovered a protein that, when blocked, can restore the drug's effectiveness.
Popular GLP-1 weight loss drugs are being misused by people struggling with eating disorde
Popular GLP-1 weight loss drugs are being misused by people struggling with eating disorde
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as Ozempic or Wegovy, have revolutionized type 2 diabetes and weight-loss management, but they have also led to some unfortunate outcomes. A recent study in JAMA Psychiatry has raised concerns that GLP-1 medications may
Scans reveal lithium distribution in bipolar disorder
A revolutionary scanning technique has revealed that lithium MRI is a powerful tool for studying how the drug interacts with the brain and could offer more personalized treatment for bipolar disorder.
Could one shot replace weekly GLP-1 drugs? DNA approach shows months-long effects in mice
Could one shot replace weekly GLP-1 drugs? DNA approach shows months-long effects in mice
Scientists at The Wistar Institute have shown that a single injection of a small, circular piece of genetic instruction can produce weight loss and blood glucose control in murine models that lasts up to 10 times as long as incretin-mimicking drugs like Ozempic and Wegovy. If sho
