Genomics provides a deeper understanding of the cause of hydrocephalus

The cerebral ventricles—four linked cavities of the brain that are packed with cerebrospinal fluid—become enlarged in hydrocephalus, or “water on the brain;” however, the cause is unknown in many instances.

Study identifies new targets for treating sorafenib-resistant hepatocellular carcinoma using CRISPR-Cas9 screening

This study is led by Xiujun Cai (Department of General Surgery, Sir Run-Run Shaw Hospital, Zhejiang University School of Medicine). Professor Xiujun Cai's research team screened the whole genome of hepatocellular carcinoma cells (HepG2) through CRISPR / cas9 system under sorafenib treatment, and screened the dominant gene in sorafenib resistance.

Study shows how innate lymphoid cells may help to treat inflammatory bowel disease

A team of researchers at Sweden’s Karolinska Institutet studied how specific immune cells known as innate lymphoid cells (ILCs), which play a role in inflammatory bowel disease (IBD), evolve into mature cells.

Spatial maps offer insights into the battle between melanoma cells and immune cells

Melanoma is a somewhat unusual cancer-;one that blooms before our very eyes, often on sun-exposed skin, and can quickly become deadly as it turns our own skin against us and spreads to other organs.

Study reveals key characteristics of immune cells in ovarian cancer

Ovarian cancer is a difficult to diagnose malignancy that is often caught at a more advanced stage. Treatments for this cancer have changed little over the past few decades, with surgery and chemotherapy being the most common therapeutic approaches.

Bioprinting bone along with two growth factor encoding genes improves bone repair

Given enough time and energy, the body will heal, but when doctors or engineers intervene, the processes do not always proceed as planned because chemicals that control and facilitate the healing process are missing.

Study shows how biodegradable gel helps immune system to keep cancer away

After tumors are surgically removed, a novel biodegradable gel increases the immune system’s capacity to keep cancer away.

New scalable method to advance maturation of human pluripotent stem cell-derived cardiomyocytes

A Mount Sinai-led team has developed a reproducible and scalable method to advance maturation of human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs)-;cells that support heart muscle contraction, generated in the lab from human stem cell lines-;which researchers say will improve approaches for disease modeling, regenerative therapies, and drug testing.

Newborn cells in patients with epilepsy, likely to provide a potential treatment

According to a study headed by researchers from USC Stem Cell and the USC Neurorestoration Center, adults may recover at least some of what they have lost by producing new brain cells, and this process is profoundly modified in patients with long-term epilepsy.

Experimental "gene silencing" therapy reduces a important driver of heart disease risk by up to 98%

Findings from a new Cleveland Clinic-led phase 1 trial show that an experimental "gene silencing" therapy reduced blood levels of lipoprotein(a), a key driver of heart disease risk, by up to 98%.

Researchers identify a set of sporadic genetic mutations behind rare brain malformations

A rare type of brain blood vessel malformation known as a cavernous angioma affects more than one million Americans and carries a lifetime risk of stroke and seizures.

HIF-1alpha inhibitor preserves the activity of insulin-producing beta cells in diabetic mice

High blood glucose is responsible for several complications in type 1 and type 2 diabetes. Researchers at Karolinska Institutet in Sweden have identified a new antidiabetic substance that preserves the activity of insulin-producing beta cells and prevents high blood glucose in mice.

Specific gene variant linked with poor response to sublingual immunotherapy for allergies

Although sublingual immunotherapy (SLIT) has become an effective treatment option for many allergies, about 20-30% of patients don’t respond to SLIT for Japanese cedar pollinosis–a highly common disease.

Study shows how the release of T-cell cytokine combined with fatty acid leads to ferroptosis

Researchers at the University of Michigan Rogel Cancer Center found that a cytokine, a category of protein that acts as messengers in the body, and a fatty acid can work together to trigger a type of cell death previously defined by studies with synthetic molecules.

Attacking a protein in prostate cancer cells stops the disease spread, research finds

Cedars-Sinai scientists discovered that attacking a protein present in prostate cancer cells could stop the disease from further spreading to various other parts of the body.

Ether anesthetics can prevent touch-induced trigger in the carnivorous Venus flytrap

Medicine has a broad repertoire of anesthetics at its medication allows patients to better endure painful treatments or even sleep through them.

Experts identify critical genes that cause coronary heart disease and trigger heart attacks

Recent research identified the major genes involved in coronary heart disease and cardiac arrest.

MIT researchers create a new cerebrovasculature atlas

While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain.

Mortality of newborns on ECMO linked with red blood cell transfusion volume

Newborns in respiratory failure who require the life-sustaining support of ECMO also require transfusion of red blood cells. But a new study indicates that the higher volume of these oxygen-carrying blood cells the babies receive, the higher their mortality rate.

New method helps distinguish bacterial DNA from human and other non-bacterial cells

For decades, a small group of cutting-edge medical researchers have been studying a biochemical, DNA tagging system, which switches genes on or off. Many have studied it in bacteria and now some have seen signs of it in, plants, flies, and even human brain tumors.
