An 'eye catching' vision discovery

Researchers at Johns Hopkins Medicine have identified a new type of light-sensitive cell in the retina of fish, which challenges current knowledge about retinal function and image vision. This discovery reveals that horizontal cells, previously thought to be only responsive to neighboring nerve cells, can also sense light.

Hepatitis C infection: treatment options equally effective, likelihood of success known early on

A landmark study finds that treatment with either of two standard antiviral drug therapies is safe and offers the best way for people infected with hepatitis C to prevent liver scarring, organ failure and death. The study showed that treating patients in early or less advanced stages of the disease leads to higher success rates.

Johns Hopkins scientists out a gene for gout

Researchers found the malfunctioning ABCG2 gene can lead to high urate levels, causing inflammation and pain. The gene is responsible for transporting urate out of the kidney and into urine, and its mutation may be linked to 10% of gout cases in Caucasians.

Johns Hopkins researchers edit genes in human stem cells

Johns Hopkins researchers have made a breakthrough in editing human stem cells, enabling the development of patient-specific therapies for rare blood diseases like paroxysmal nocturnal hemoglobinuria (PNH). The team successfully targeted and edited a gene responsible for causing PNH, improving on standard gene targeting technology.

New lead on malaria treatment

Researchers at Johns Hopkins University School of Medicine have discovered a natural compound that can stop malaria parasite growth, interacting with the parasite's MetAP2 protein. The compound, fumarranol, was found to be less toxic than existing medications and showed promise in treating malaria in mice.

New evidence ties gene to Alzheimer's

Researchers at Johns Hopkins University found a link between genetic variations in the neuroglobin gene and an increased risk of Alzheimer's disease. The study, published in Neurobiology of Aging, suggests that lower levels of neuroglobin may contribute to the development of Alzheimer's.

When cells reach out and touch

Scientists at Johns Hopkins discovered that cell-to-cell contact revs up microRNA production, a key regulator of gene expression. The study found that physical contact is the critical factor influencing microRNA abundance, with increasing cell density leading to increased microRNA production in all tested cell lines.

Gutsy germs succumb to baby broccoli

Eating two and a half ounces of baby broccoli sprouts daily for two months reduced HpSA levels by over 40% in infected individuals, suggesting potential protection against gastritis, ulcers, and stomach cancer. However, the study did not cure infection or eradicate H. pylori colonization.

Starve a yeast, sweeten its lifespan

Researchers found that acetylation affects yeast lifespan through the NuA4 enzyme complex, which also controls sugar production in cells. This discovery may have implications for understanding aging and human diseases, as the mechanisms identified are conserved across species.

6.5 million more patients might benefit from statins to prevent heart attacks, strokes

Researchers estimate that around 6.5 million older adults with low cholesterol and high C-reactive protein levels might benefit from statin therapy to prevent cardiovascular events. Expanding prescribing criteria to include CRP levels could potentially prevent thousands of heart attacks, strokes, and deaths each year.

What's feeding cancer cells?

Scientists at Johns Hopkins University have discovered how the Myc cancer-promoting gene uses microRNAs to control glutamine, a major energy source for cancer cells. This finding may lead to identifying new pathways to target for designing drugs with fewer side effects.
