Scientists find sea corals are source of sought-after "anti-cancer" compound

23 hours 59 minutes ago
The bottom of the ocean is full of mysteries but scientists have recently uncovered one of its best-kept secrets. For 25 years, drug hunters have been searching for the source of a natural chemical that had shown promise in initial studies for treating cancer. Now, researchers at University of Utah Health report that easy-to-find soft corals - flexible corals that resemble underwater plants - make the elusive compound.

Study identifies new molecular target for cancer therapy

3 days 23 hours ago
Researchers with The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) have identified a new molecular drug target that could result in new cancer drugs with fewer side effects.

Previous studies have shown that vascular endothelial growth factor-A (VEGF-A) ­- a potent cytokine (signaling protein) - and dopamine (a neurotransmitter/neurohormone) ­­play essential roles in many physiological and pathological functions.

FDA urges drug manufacturers to develop risk management plans to promote a dtronger, resilient drug supply chain

4 days 23 hours ago
Drug shortages pose a significant public health threat as they can delay, and in some cases, even deny critically needed care for patients. Over the past decade, the FDA’s efforts have contributed to fewer new drug shortages and reduced the time to resolve existing drug shortages. This is due, in part, to authorities the agency now has, including those added by the Food and Drug Administration Safety and Innovation Act.

"Natural immunity" from omicron is weak and limited, study finds

5 days 23 hours ago
In unvaccinated people, infection with the Omicron variant of SARS-CoV-2 provides little long-term immunity against other variants, according to a new study by researchers at Gladstone Institutes and UC San Francisco (UCSF), published today in the journal Nature.

In experiments using mice and blood samples from donors who were infected with Omicron, the team found that the Omicron variant induces only a weak immune response.

Nearly 700,000 US hospitalizations and 110,000 deaths prevented from the Pfizer-BioNTech COVID-19 vaccine

Blocking spike captors to counter COVID

1 week 5 days ago
Despite the effectiveness of vaccination campaigns worldwide, the threat posed by COVID-19 still exists. First of all, a new SARS-CoV-2 variant could very well emerge that may not respond to current vaccines. Secondly, the efficacy of the vaccines in the long term remains unknown. Lastly, cases of acute infection are continuing to be reported. And yet, there is no effective treatment to date.

1 week 6 days ago
Pfizer Inc. (NYSE: PFE) and Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN) have entered into a definitive agreement under which Pfizer will acquire Biohaven, the maker of NURTEC® ODT, an innovative dual-acting migraine therapy approved for both acute treatment and episodic prevention of migraine in adults.

Recurring brain tumor growth is halted with new drug

2 weeks ago
When a non-metastatic brain tumor - a meningioma - recurs after surgery and radiation treatment, a patient is out of options. No drugs are approved for these aggressive tumors, which occur in up to 20% of cases and can lead to patient disability or even death.

But now Northwestern Medicine scientists, in an international collaboration with scientists at the University of California, San Francisco and the University of Hong Kong, have identified a drug that inhibits growth of the most aggressive meningiomas and how to most accurately identify which meningiomas will respond to the drug.

FDA limits use of Janssen COVID-19 vaccine to certain individuals

2 weeks 3 days ago
The U.S. Food and Drug Administration has limited the authorized use of the Janssen COVID-19 Vaccine to individuals 18 years of age and older for whom other authorized or approved COVID-19 vaccines are not accessible or clinically appropriate, and to individuals 18 years of age and older who elect to receive the Janssen COVID-19 Vaccine because they would otherwise not receive a COVID-19 vaccine.

Investigational COVID mucosal vaccine protects against disease and transmission

2 weeks 4 days ago
In animal studies that mimic human exposures, an investigational COVID vaccine designed to be taken orally not only protects the host, but also decreases the airborne spread of the virus to other close contacts.

The study, led by Duke researcher Stephanie N. Langel, Ph.D., demonstrated the potential of a COVID vaccine that works through the mucosal tissue to neutralize the SARS-CoV-2 virus, limiting infections and the spread of active virus in airborne particles.

Using AI to analyze large amounts of biological data

2 weeks 4 days ago
Researchers at the University of Missouri are applying a form of artificial intelligence (AI) - previously used to analyze how National Basketball Association (NBA) players move their bodies - to now help scientists develop new drug therapies for medical treatments targeting cancers and other diseases.
