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.

New antibody "cocktail" may help counter the Lassa virus

The finding, made with the use of the Advanced Photon Source, shows a new way to exploit monoclonal antibodies to subvert the "shield" of the virus, potentially paving the way for new therapies.

Genomic study helps to better understand the origins, history of Tibetan and Sherpa ethnic groups

The Tibetan Plateau, the highest and largest plateau above sea level, is one of the harshest environments settled by humans.

Study suggests new strategy for treating arrhythmogenic cardiomyopathy

University of Utah Health scientists have corrected abnormal heart rhythms in mice by restoring healthy levels of a protein that heart cells need to establish connections with one another.

Cancer cells use new DNA repair mechanism to recover from next-generation cancer radiation therapy

A team of scientists led by Dr. Kei-ichi TAKATA from the Center for Genomic Integrity within the Institute for Basic Science (IBS), has discovered a new type of DNA repair mechanism that cancer cells use to recover from next-generation cancer radiation therapy.

Delaying paralysis in ALS by using designer DNA drug

In virtually all persons with amyotrophic lateral sclerosis (ALS) and in up to half of all cases of Alzheimer's disease (AD) and frontotemporal dementia, a protein called TDP-43 is lost from its normal location in the nucleus of the cell.

Using a programmable control switch to deliver therapeutic RNA molecules to target cells

Using an RNA sensor, MIT engineers have designed a new way to trigger cells to turn on a synthetic gene.

Losing a productive type of beta cell may contribute to the development of diabetes

Multiple types of beta cells produce insulin in the pancreas, helping to balance blood sugar levels. Losing a particularly productive type of beta cell may contribute to the development of diabetes, according to a new study by Weill Cornell Medicine investigators.

Common commensal gut bacterium uses phase separation of Rho factor to thrive in the mammalian gut

The common commensal gut bacterium Bacteroides thetaiotaomicron uses phase separation of the transcription termination factor Rho to colonize and thrive in the mammalian gut, according to a new study in mice.

The impact of genome doubling on the development of cancer

Since a single cell has 2–3 m of DNA, the only method to store it is in tight coils. The answer is chromatin, a DNA-protein complex that is wrapped around histone proteins.

Highly sensitive bioluminescent platform for nucleic acid detection

Despite significant advances, numerous highly sensitive viral disease diagnostic tests even now require complex techniques to prepare a sample or decipher a result, making them inconvenient for point-of-care settings or areas with limited resources.

Highlighting a potential sex‐specific precision immunotherapy strategy

Immunotherapy is an effective form of treatment for various types of cancer. However, its effect on pancreatic cancer is restricted and varies between men and women. Karolinska Institutet scientists have observed a possible explanation for this gender difference.

First molecular images of olfaction sets the stage to create novel smells

Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.

Gene that regulates cadmium distribution between leaf and grain in rice

Due to its accumulation in crops, specifically rice, cadmium (Cd), a hazardous heavy metal contaminant of cultivated land, poses a threat to human health. Thus, it is vital to develop methods to prevent Cd from accumulating in rice grains.

TurboID-based proximity labeling in meiotic cells of Arabidopsis thaliana

During meiosis, reshuffling of genetic information between homologous chromosomes through meiotic recombination creates variable gametes and hence genetic variation in offsprings.

Effective backup mechanism ensures efficient antimicrobial responses in humans

In the human body, virus particles are identified by pattern recognition receptors (PRRs) either within or on the cell surface. When a receptor is activated, a signaling cascade is initiated, which results in the production and release of signaling molecules like interferons and cytokines.

Experts unravel a vast network that shows how cells adjust in real-time to withstand stresses

Every minute of every day, our body adapts to meet the needs of each moment. When we binge on carbs, exercise, or become sick, chemical reactions inside our cells switch on, slow down, or shift strategy so that we have the energy and strength we need.

Study investigates schizophrenia risk across African ancestry

Researchers have identified two previously unknown genes linked to schizophrenia and newly implicated a third gene as carrying risk for both schizophrenia and autism. Led by the Icahn School of Medicine at Mount Sinai, the multi-center study further demonstrated that the schizophrenia risk conferred by these rare damaging variants is conserved across ethnicities. The study may also point to new therapeutics.

Bacteriophages might hold the key to fighting antibiotic resistance

As conventional antibiotics continue to lose effectiveness against evolving pathogens, scientists are keen to employ the bacteria-killing techniques perfected by bacteriophages, the viruses that infect bacteria.

Neural-network-based image recognition models for examining SCC defects

Scientists from Tokyo Metropolitan University have used machine learning to automate the identification of defects in sister chromatid cohesion. They trained a convolutional neural network (CNN) with microscopy images of individual stained chromosomes, identified by researchers as having or not having cohesion defects. After training, it was able to successfully classify 73.1% of new images. Automation promises better statistics, and more insight into the wide range of disorders which cause cohesion defects.

New class of oral drugs inhibits a diverse range of SARS-CoV-2 strains

The constant evolution of new COVID-19 variants makes it critical for clinicians to have multiple therapies in their arsenal for treating drug-resistant infections. Researchers have now discovered that a new class of oral drugs that acts directly on human cells can inhibit a diverse range of pathogenic SARS-CoV-2 strains.
