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.

KIF13B protects heart function during sepsis by regulating lipid metabolism

Sepsis, a life-threatening condition caused by dysregulated host response to infection, remains a major cause of global mortality.

Study reveals epigenetic adaptation of beta cells across lifespan and disease

As people age, most maintain normal blood sugar even as insulin resistance tends to rise. New research suggests that pancreatic beta cells help meet this demand through gradual epigenetic changes in regulatory regions of the genome that support beta-cell identity and function.

GADD45B promotes apoptosis in intestinal injury through DNA demethylation

Intestinal ischemia/reperfusion (I/R) injury is a common pathophysiological phenomenon that is widely present in various primary intestinal diseases and systemic critical illnesses, potentially leading to multiple organ dysfunction and failure, with high morbidity and mortality.

AI-driven model predicts type 1 diabetes risk with greater accuracy

Researchers use machine learning and genetic analysis to uncover type 1 diabetes risk factors, improving prediction accuracy and identifying patient subtypes.

Protective brain pathway may slow Parkinson’s progression in females

Scientists have identified a protective brain pathway that may help slow the progression of Parkinson's disease by strengthening the brain's own dopamine‑producing neurons, but the positive effect was only observed in females.

AI model reads genetic code to trace evolutionary history

Researchers at the University of Oregon have developed an artificial intelligence tool that can read genetic code the way large language models like ChatGPT read text. Scanning the genome for biological mutation patterns, the computer model traces pairs of genes back in time to their last common ancestor.

New genomic study tracks rare blood disease in children

Aplastic anemia is a rare, life-threatening blood disorder where patients are unable to make enough blood cells due to the immune system's attack on blood stem cells. The condition can progress to myelodysplastic syndrome (MDS) and leukemia. A study led by scientists at St. Jude Children's Research Hospital, with multiple collaborating institutions, used state-of-the-art genomic techniques to profile 619 children and adults with aplastic anemia.

Food timing may shape how T cells respond to infection and therapy

Short-term nutritional state can reshape T cell metabolism, with post-meal lipid metabolism enhancing T cell metabolic capacity, cytokine production, and persistence after activation. The study identifies triglyceride-rich chylomicrons as key drivers of this effect, suggesting nutritional timing may matter for immune monitoring, vaccination research, and cell-therapy manufacturing.

Five-target drug beats GLP-1/GIP therapy in obese diabetic mice

A Nature study reports a single-molecule GLP-1–GIP–lanifibranor quintuple agonist that targets incretin receptor-expressing cells while activating PPARα/γ/δ pathways. In obese and insulin-resistant mice, the compound reduced body weight, food intake, and hyperglycaemia more effectively than semaglutide or GLP-1R–GIPR co-agonism, while remaining a preclinical finding.

New genetic risk report reveals hidden heart disease risk before symptoms appear

Researchers developed and externally validated integrated polygenic risk scores for eight cardiovascular conditions using large U.S.-based biobank data. The clinically orderable report may help identify inherited cardiovascular risk that traditional clinical markers can miss, although broader prospective validation is still needed.

T1GRS model enhances prediction of genetic risk for Type 1 diabetes

In people with Type 1 diabetes (T1D), the immune system shuts down the body's ability to make the hormone insulin, responsible for regulating blood sugar and providing cells with glucose to produce energy.

Molecular switch protein Ten4 guides neuron migration in the developing brain

During brain development, neurons can regulate their movement until they reach their final destination thanks to a "molecular switch" involving the protein Teneurin 4 (Ten4).

Dangerous water bead ingestions increase among young children

A new study reveals that ingestions of water beads by young children have surged in recent years. Researchers at the Center for Injury Research and Policy of the Abigail Wexner Research Institute at Nationwide Children's Hospital and the Central Ohio Poison Center analyzed calls to U.S. poison centers and found an alarming 6,532% increase in the rate of reported water bead ingestions among children younger than 6 years from 2019 to 2023, followed by a 24% decrease from 2023 to 2024.
