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.

Robust method for induced pluripotent stem cell culture

Different types of cells, such as the heart, liver, blood, and sperm cells, have characteristics that help them perform their specific functions in the body. In general, those traits are hard-wired. A heart cell will not randomly transform into a liver cell if not stimulated.

Artificial intelligence creates proteins to hasten chemical reactions

Scientists have for the first time utilized machine learning to design whole new enzymes, which are proteins that quicken chemical reactions. In the realm of protein design, this is a crucial development since new enzymes can find several applications in both industrial manufacture and medicine.

New model describes the enormous range of DNA in nature

Why neutral sequences, frequently referred to as “junk DNA,” are not removed from the genomes of living things in nature and persist there even millions of years later is a scientific mystery that could have a possible answer according to a new model created at Tel Aviv University.

Study illuminates how lung cells protect themselves against RNA viral infection

A new University of California, Irvine-led study uncovers how a protein, APOBEC3B, could protect cells against many different types of RNA viruses like respiratory syncytial virus (RSV), SARS-CoV2, influenza virus, poliovirus and measles, helping to prevent disease.

Mount Sinai researchers illuminate the role of DNA methylation in Alzheimer's disease

Mount Sinai researchers have published a study in Alzheimer's & Dementia: The Journal of the Alzheimer's Association that sheds new light on the role of DNA methylation in Alzheimer's disease (AD).

Monitoring bovine meat and milk factor protein expression could enable colorectal cancer detection

Bovine meat and milk factors (BMMFs)-; initially identified by de Villiers et al. in 2014-; represent a class of infectious agents in beef and cow's milk that have been linked to the development of cancer.

Novel model system helps studying human ovarian biology

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

Study reveals how chloroplast ATP synthase regulates ATP production in organisms

ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called "chloroplast ATP synthase" (CFoCF1).

New host protease determinants facilitating the infection of SARS-CoV-2 identified

Researchers from Department of Microbiology, School of Clinical Medicine, LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has identified novel host protease determinants, that facilitate the infection of SARS-CoV-2, including the Omicron variant, which provided new targets for combating the pandemic.

New insights into the mechanism underlying the immunomodulatory effects of polyphenols

PCB2DG, a polyphenol with anti-inflammatory properties, works by targeting and directly interacting with the major glutamine transporter protein, alanine serine cysteine transporter 2 (ASCT2), to inhibit the uptake of glutamine, an important amino acid found in the blood.

ApoE4 from neurons plays a critical role in Alzheimer's disease

Of all the known genetic risk factors for late-onset Alzheimer's disease, the strongest is a gene for the protein called ApoE4.

New biomarker helps identify biological age

Once considered to be incompetent in encoding proteins due to their simple monotonous DNA repetitions, tiny telomeres at the tips of human chromosomes now appear to have a powerful biological function that could help better understand cancer and aging.

Analyzing the existence of unknown miniproteins

Evolutionarily young miniproteins are unique in humans, and scientists have recently found thousands of them.

Toxic protein likely to be the cause of two rare genetic disorders identified

Scientists at the National Institutes of Health and their co-workers reported that DUX4, a toxic protein produced by the body, might just be the reason for two completely different rare genetic disorders.

Accelerating the structure-guided discovery of chemogenetic tools

In order to more fully understand how diseases arise in the brain, scientists must unravel the intricate way neurons relay messages (either chemical or electrical) along a complex web of nerve cells. One way is by using a tool called DREADDs, which stands for Designer Receptors Activated by Designer Drugs.

Iron-dependent cell death can be used to improve immunotherapies against liver cancer

Iron-dependent cell death (ferroptosis) is a type of programmed cell death by means of which the body kills off diseased, defective or superfluous cells.

20 Feb 2023

Novel molecule prevents cells from infection with SARS-COV-2

The virus that causes COVID-19, called SARS-CoV-2, uses its spike protein in order to stick to and infect our cells. The final step for the virus to enter our cells is for part of its spike protein to act like a twist tie, forcing the host cell's outer membrane to fuse with the virus.
