Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Experimental drug prolongs survival, improves muscle function in mice severe Duchenne muscular dystrophy

Researchers at Johns Hopkins Medicine report that an experimental drug first developed to treat kidney disease prolongs survival and improves muscle function in mice genetically engineered to develop a severe form of Duchenne muscular dystrophy (DMD).

In vitro skeletal muscle models could lead to personalized medicine for type 2 diabetes

Abnormally high blood sugar (glucose) levels can result in Type 2 diabetes when things go awry with the body's skeletal muscle, which plays a key role in regulating glucose.

Study shows vaccine-derived poliovirus in infant with severe immunodeficiency

Researchers identified type 3 vaccine-derived poliovirus (VDPV) in an infant.

Researchers join forces to 'map' specific variations in more than 25 key cardiac disease genes

One in 100 people have genetic variations that can cause potentially life-threatening heart conditions, including high cholesterol (lipid disorders), heart muscle disease (cardiomyopathies), and abnormal heart rhythms (arrhythmias).

Brain organoids shed light into the evolution of the human brain

Animal studies on great apes have long been banned in Europe for ethical reasons. For the question pursued here, so-called organoids, i.e. three-dimensional cell structures a few millimeters in size that are grown in the laboratory, are an alternative to animal experiments.

Molecular explanation for the contribution of autophagy to BAT energy metabolism

Obesity is a growing global health problem and its prevalence has tripled since 1975. More than 650 million people are affected by this condition worldwide, and 28% of people in Spain over 18 years of age have this complex pathology. Obesity is linked to conditions such as type II diabetes, cardiovascular disease, osteoarthritis, and certain forms of cancer.

Forecasting COVID-19 surges based on SARS-CoV-2 mutation surveillance

Researchers predicted surges in SARS-CoV-2 infections based on alterations in SARS-CoV-2 mutations.

Study investigates the efficacy and safety of selpercatinib in a diverse group of patients

The highly selective RET inhibitor selpercatinib was well-tolerated and achieved durable objective responses across multiple tumor types in the Phase I/II LIBRETTO-001 trial, according to researchers from The University of Texas MD Anderson Cancer Center.

Treg transplantation improves bone remodeling, study says

The building blocks of a structure consist of load-bearing elements that rarely change despite renovations or repairs. They remain intact and consistent over time, but in the human body, our building blocks do just the opposite.

The impact of the infant gut microbiome on vaccine efficacy

A new study reports the effect of the infant gut microbiome on vaccine efficacy.

Is there a right time for eating?

In a recent study published in the journal Cell Metabolism, researchers assessed how calorie or energy intake (EI) time influences calorie distribution and all energy expenditure (EE) components, which, in turn, impact energy balance and weight loss in healthy obese people.

First report of a SARS-CoV-2 variant with an ORF7a deletion that dominated an outbreak

In a recent study posted to the medRxiv* preprint server, researchers in Australia determined whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta-ORF7aΔ17del [open reading frame 7a protein with 17-nucleotide (nt) frameshift-inducing deletion] variant has a fitness advantage over the Delta variant lacking the ORF7aΔ17del deletion (Delta-ORF7aintact) and/or the SARS-CoV-2 lineage (A.2.2).

SARS-CoV-2 breakthrough infection in vaccinated individuals induces virus-specific nasal T cells of broad specificity

Long-lasting immune cells that specifically recognize the SARS-CoV-2 virus were found in the noses of people who were infected following vaccination.

LJI scientists uncover major clue toward developing new antiviral therapies against flaviviruses

Zika virus has a trick up its sleeve. Once inside the body, the virus likes to make a bee line for dendritic cells, the cells we rely on to launch an effective immune response.

Mucosal vaccination triggers superior T cell response against SARS-CoV-2 variants

In a recent study posted to the bioRxiv* server, researchers in Singapore and the United States demonstrated that intranasal (I.N.) delivery of a mucosal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination triggered a superior T cell response compared to an equivalent dose of antigen delivered by the subcutaneous (S.C.) route.

Antibiotics accelerate metastatic bone growth in mice with melanoma by depleting intestinal flora

The use of broad-spectrum antibiotics in mice with malignant melanoma, an aggressive form of skin cancer, accelerated their metastatic bone growth, likely because the drugs depleted the mice's intestinal flora and weakened their immune response, according to a new study by researchers at Emory University in Atlanta.

Blocking FNDC5 prevents cancer-induced cachexia in mice

The severe muscle atrophy and weakness commonly associated with cancer growth (i.e., cachexia) can be prevented simply by being deprived of FNDC5, the precursor of the exercise hormone irisin, researchers from the Indiana University School of Medicine have found.
