Anti-Malaria Drugs Have Shown Promise in Treating Cancer, and Now Researchers Know Why

Anti-malaria drugs known as chloroquines have been repurposed to treat cancer for decades, but until now no one knew exactly what the chloroquines were targeting when they attack a tumor. Now, researchers from the Abramson Cancer Center of the University of Pennsylvania say they have identified that target – an enzyme called […]

A Lung Cancer Diagnosis and Treatment Revolution

Over the past 30 years, interventional cardiology has transformed heart care — replacing many interventions that used to require open-heart surgery with less invasive procedures. Today, that same revolution has arrived for pulmonary medicine with interventional pulmonology, or IP. The subspecialty offers a variety of minimally invasive procedures to diagnose […]

Cells beneath the skin explain differences in healing

Differences in the cells that give skin its resilience and strength during wound repair may explain why individuals heal differently, according to a new Yale study published in the journal Science. Fibroblasts, the cells that form the protein structure beneath the surface of the skin, were once thought to be […]

Early gut bacteria shape intestinal ecosystem

The study suggests that the order in which bacterial species stake out unclaimed territory in the gut can shape an intestinal ecosystem for a lifetime, potentially shifting the odds of certain health outcomes in the process. Though timing wasn’t everything, multiple experiments showed that species given early access to the […]

Researchers stop ‘sneaky’ cancer cells in their tracks

A new study by University of Minnesota biomedical engineers shows how they stopped cancer cells from moving and spreading, even when the cells changed their movements. The discovery could have a major impact on millions of people undergoing therapies to prevent the spread of cancer within the body. The research […]

Dementia Study First in a Series on Health Needs and Challenges of LGBTQ Seniors

In the first paper to emerge from a series of research projects aimed at understanding the health needs of older adults who identify as lesbian, gay, bisexual, transgender and queer (LGBTQ), Jason Flatt of the Institute for Health & Aging at the UC San Francisco School of Nursing found that nearly 25 percent of the LGBT adults aged […]

Fish genes hold key to repairing damaged hearts

The Mexican tetra fish can repair its heart after damage — something researchers have been striving to achieve in humans for years. Now, new research funded by the British Heart Foundation (BHF) published in Cell Reports suggests that a gene called lrrc10 may hold the key to this fish’s remarkable ability. Around 1.5 million […]

Cutting the legs off cancer

Melanoma skin cancer tumors grow larger and are more likely to metastasize due to interactions between a pair of molecules, according to experiments in mice and human cells. The results may restore the potential for a type of cancer therapy previously abandoned in clinical trials. The results also implicate one […]

Modeling the most common form of vision loss in older adults

Age-related macular degeneration (AMD) affects roughly 200,000 individuals in the United States each year. In most, it comes on slowly, gradually blurring the central field of vision used for activities like reading and driving. While treatments exist to slow its progression, there is no cure. A team led by Kathleen Boesze-Battaglia of […]

First mapping of cells in the early human placenta to advance research on problem pregnancies

To treat and prevent pregnancy-related disorders, researchers must understand not only what can go wrong, but when. Complications, such as preeclampsia and pre-term birth, often occur in the second or third trimester, and most research to date has focused on those later stages of pregnancy. But the biological events that […]

New method for studying gene expression could improve understanding of brain disease

It takes a lot of cells to make a human brain. The organ houses not only an enormous quantity of neurons (tens of billions), but also an impressive diversity of neuron types. In recent years, scientists have been developing inventories of these cell classes—information that will be essential for understanding […]
