Gene

A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

What are Genes?

Deoxyribonucleic acid (DNA) is the chemical information database that carries the complete set of instructions for the cell as to the nature of the proteins produced by it, its life span, maturity, function and death. Genes are the working subunits of DNA. Each gene contains a particular set of instructions, usually coding for a particular protein or for a particular function.

Dual-targeted therapy shows promise against metastatic triple-negative breast cancer

A new preclinical study suggests that attacking triple-negative breast cancer (TNBC) in two ways at once can kill cancer cells, slow tumor growth and limit the cancer's spread. Researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) developed the approach.

Scientists studied one million immune cells and found clues to future disease risk

Researchers developed a single-cell atlas of one million human neutrophils, identifying distinct immune cell populations and gene-expression patterns across tissues, infections, cancer, and other health conditions. Certain neutrophil signatures were associated with metabolic dysfunction, cancer outcomes, and mortality, while higher routine neutrophil counts, even within the normal range, were linked to an increased risk of chronic disease.

Unstable immune cells linked to severe cancer immunotherapy side effects

Scientists at the University of Pittsburgh uncovered the unstable immune cells that can cause up to 40% of immunotherapy patients to experience serious side effects and showed that diet and microbiome composition influence the side effect's severity.

Study identifies blood proteins associated with aggressive prostate cancer risk

Proteins linked to the immune system, cell adhesion, blood vessel formation and known prostate cancer genes, were associated with the future risk of developing prostate cancer, including aggressive disease, in a new study led by researchers at Oxford Population Health.

Semaglutide and teduglutide reduce immune-driven gut injury in mice

Researchers found that gut-derived GLP-1 and GLP-2 signaling helped protect mice against T cell-induced intestinal injury, with GLP-1R primarily regulating inflammation and GLP-2R supporting intestinal repair. Semaglutide and teduglutide, administered separately or together, reduced acute intestinal damage in mice lacking intestinal proglucagon, suggesting potential avenues for investigating treatments for immune-mediated gut injury.

Penn State study identifies new regulator of jumping genes

As much as half of the human genome is composed of so-called "jumping genes." These DNA sequences can make copies of themselves that are inserted back into the genome at another location, playing a significant functional role in creating the diversity that drives evolution and in regulating how other genes are turned on or off.
