Early Skin Cancer More Accurately Diagnosed by Dermatologist Than Other Providers

Physician assistants (PAs) are increasingly used in dermatology practices to cut costs and improve access to care, but are more likely than dermatologists to perform unnecessary skin biopsies to check for cancer, while being less likely to accurately diagnose early stage skin cancers, according to new research conducted by the University of Pittsburgh School of Medicine.

Largest-Ever Genetic Study of Stroke Provides New Insight Into the Disease

An international research group, including scientists at the University of Maryland School of Medicine, studying 520,000 people from around the world has identified 22 new genetic risk factors for stroke, tripling the number of gene regions known to affect stroke risk. The results show that stroke shares genetic influences with other vascular conditions, especially blood […]

Stem Cell Therapy May Help Reverse Effects of Premature Menopause, Restore Fertility

Young women with premature ovarian insufficiency (POI) may be able to use their own bone marrow stem cells to rejuvenate their ovaries and avoid the effects of premature menopause, new research suggests. The preliminary results from the ongoing ROSE clinical trial will be presented Tuesday at ENDO 2018, the 100th annual meeting of the Endocrine Society, in […]

Improved Capture of Cancer Cells Could Aid in Disease Tracking

Researchers at the University of North Carolina Lineberger Comprehensive Cancer Center and University of Wisconsin-Madison have demonstrated improved methods of capturing free-floating cancer cells that are cast-off from tumors, and circulating in the blood. If these cast-off cells can be accurately counted, they could provide an additional way to track treatment or screen for disease. […]

Potential new approach to the treatment of multiple sclerosis

A prospective new method of treating patients with multiple sclerosis has been proposed by researchers of the Mainz University Medical Center working in cooperation with researchers of the University of Montreal. In model trials and experiments employing human endothelial cells, they discovered that the EGFL7 protein hinders the migration of immune cells into the central […]

Researchers Move Closer to Improved Method of Detecting Breast Cancer

Engineering researchers at the University of Arkansas have moved closer to developing an alternative method of detecting and possibly treating breast cancer. The researchers, led by Magda El-Shenawee, professor of electrical engineering, work with pulsed, terahertz imaging, a type of electromagnetic radiation technology previously used to find land mines. They adapted the technology to detect […]

Researchers Successfully Reverse Alzheimer’s Disease in Mouse Model

A team of researchers from the Cleveland Clinic Lerner Research Institute have found that gradually depleting an enzyme called BACE1 completely reverses the formation of amyloid plaques in the brains of mice with Alzheimer’s disease, thereby improving the animals’ cognitive function. The study, which will be published February 14 in the Journal of Experimental Medicine, raises […]

New explanation for why airways close in asthma holds promise for future class of drugs

 Houston Methodist researchers have a new explanation for what causes the lungs’ airways to close during asthma attacks that could change the lives of the 300 million people worldwide who suffer from asthma. The discovery holds promise for developing a new class of drugs that is radically different from the steroids currently used to treat […]

Enzyme Inhibitor Combined with Chemotherapy Delays Glioblastoma Growth

 In animal experiments, a human-derived glioblastoma significantly regressed when treated with the combination of an experimental enzyme inhibitor and the standard glioblastoma chemotherapy drug, temozolomide. The regression seen in this combination therapy of temozolomide and the inhibitor SLC-0111 — which targets the enzyme carbonic anhydrase 9, or CA9 — was greater than that seen with […]

Texas A&M Research Shows Biological Clocks Could Improve Brain Cancer Treatment

Biological clocks throughout the body play a major role in human health and performance, from sleep and energy use to how food is metabolized and even stroke severity. Now, Texas A&M University researchers found that circadian rhythms could hold the key to novel therapies for glioblastoma, the most prevalent type of brain cancer in adults—and one with a grim prognosis.

Immune Cells Play Key Role in Early Breast Cancer Metastasis Even Before a Tumor Develops

Mount Sinai researchers have discovered that normal immune cells called macrophages, which reside in healthy breast tissue surrounding milk ducts, play a major role in helping early breast cancer cells leave the breast for other parts of the body, potentially creating metastasis before a tumor has even developed, according to a study published in Nature Communications.

Researchers Map Molecular Interaction That Prevents Aggressive Breast Cancer

Researchers in Italy have discovered how specific versions of a protein called Numb protect the key tumor suppressor p53 from destruction. The study, which will be published December 21 in the Journal of Cell Biology, suggests that the loss of these particular Numb proteins makes breast cancers more aggressive and resistant to chemotherapy, but points the […]

Harnessing Sperm to Treat Gynecological Diseases

Delivering drugs specifically to cancer cells is one approach researchers are taking to minimize treatment side effects. Stem cells, bacteria and other carriers have been tested as tiny delivery vehicles. Now a new potential drug carrier to treat gynecological conditions has joined the fleet: sperm. Scientistsreport in the journal ACS Nano that they have exploited the swimming […]

Researchers Identify Epigenetic Orchestrator of Pancreatic Cancer Cells

Genentech researchers have identified an enzyme that shifts pancreatic cancer cells to a more aggressive, drug-resistant state by epigenetically modifying the cells’ chromatin. The study, which will be published December 11 in the Journal of Cell Biology, suggests that targeting this enzyme could make pancreatic cancer cells more vulnerable to existing therapies that currently have only […]

Mitochondrial Protein in Cardiac Muscle Cells Linked to Heart Failure, Study Finds

Reducing a protein found in the mitochondria of cardiac muscle cells initiates cardiac dysfunction and heart failure, a finding that could provide insight for new treatments for cardiovascular diseases, a study led by Georgia State University has shown. The researchers discovered that reducing an outer mitochondrial membrane protein, FUN14 domain containing 1 (FUNDC1), in cardiac […]
