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.

New study reveals CRISPR enzyme that responds to human DNA methylation

Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells. Now, a team of scientists from Wageningen University & Research and Van Andel Institute has identified a way to exploit this distinction. Using a variant of CRISPR, a modern tool for editing DNA, they distinguished tumor DNA from healthy DNA and selectively cut only the former. The study, published today in Nature, is an early but promising step toward a cancer therapy that targets and destroys tumor cells with high precision.

Synthetic biology approach boosts growth of implanted liver tissue

In patients developing end-stage liver disease, the damage has become too severe for the liver's normally extraordinary regenerative capacity to repair or compensate for it. Once this "point of no return" has been reached, the only option is an organ transplant.

High-resolution study maps molecular differences across six human cortical regions

A new analysis of individual brain cells across several human brain regions reveals subtle but widespread differences in gene activity between male and female brains. This may help explain why some psychiatric and neurological disorders appear to affect the biological sexes differently, researchers report.

Scientists discover BRCA links to head and neck cancer risks

An international group led by researchers from the RIKEN Center for Integrative Medical Sciences (IMS) in Japan have discovered associations between pathogenic variants of the BRCA 1 and 2 genes and four types of cancer. Published in ESMO Open, the findings expand the potential for personalized medicine to several cancer types that currently have limited treatment options and poor prognoses.

How the immune system may influence Alzheimer’s, Parkinson’s, and related diseases

This review argues that neurodegeneration is shaped not only by toxic protein buildup but also by immune signaling, with microglia and T cells able to either protect the brain or worsen damage depending on context. It also highlights aging, head injury, and viral infection as major forces that reshape CNS immunity and may influence disease progression and future treatment strategies.

New research reveals how bacteria "selflessly" share DNA through GTAs

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).

Epigenetic changes allow cancer cells to shift identity and survive drugs

Cancer drugs are designed to shut tumors down. But sometimes, in the very act of attacking a tumor, treatment can also help a small fraction of cancer cells become harder to kill. A new study from researchers at the Institute for Systems Biology (ISB) shows that cancer cells may begin escaping therapy much earlier - as the therapy itself triggers a stress response that drives some cancer cells into a temporary drug-tolerant state.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

Migraine genes linked to worse headaches after concussion in children

A University of Calgary-led study has found evidence that children with genes predisposing to migraine might have an increased risk of having more headaches after a concussion, which are known to be linked to prolonged symptoms up to six-months after the injury.

Mitochondrial activity keeps dendritic cells ready to fight disease

Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) show that active mitochondria maintain dendritic cells, the immune system's sentinels, in a "ready-to-respond" state, linking cellular metabolism to gene regulation and T-cell activation.

Semaglutide improves liver function independently of weight loss

Researchers at Toronto's Sinai Health have found that semaglutide – the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1 – acts directly on a subset of liver cells to improve organ function and does so independently of weight loss.
