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.

Sleep duration and genetics interact to affect functional health

Lifestyle-behavioral factors and socioeconomic status play an important role in shaping healthy aging, but their effects may differ depending on your DNA, according to a new international study led by Adelaide University researchers.

Polygenic embryo testing raises ethical concerns beyond disease prevention

For more than four decades, in vitro fertilization (IVF) has helped families have children. Scientists estimate that more than 10 million people worldwide have been born through IVF and related assisted reproductive technologies, according to the International Committee for Monitoring Assisted Reproductive Technologies.

How could bisphenol A raise depression risk? Study identifies six key molecular targets

An integrative Translational Psychiatry study linked BPA exposure to major depressive disorder by identifying 571 shared targets and six core genes, with genetic, transcriptomic, docking, and mouse-model data supporting plausible mechanistic pathways. The strongest signals pointed to AKT1, SRC, PLCG2, and JAK3 as potential contributors, while EGFR appeared protective.

How vitamin D in the first 1,000 days may shape lifelong health

This narrative review argues that vitamin D is clearly important for skeletal health during the first 1,000 days of life and may also shape immune, metabolic, and selected neurodevelopmental pathways during early development. However, the authors stress that human evidence for most non-skeletal outcomes remains heterogeneous, with benefits appearing most consistent in populations with baseline deficiency.

Innate immunity genes may influence earlier breast cancer onset in BRCA1 carriers

Damaging variants in genes involved in a rapid immune response (innate immunity) are significantly linked to earlier breast cancer onset in carriers of the harmful BRCA1 genetic mutation, reveal preliminary findings published online in the Journal of Medical Genetics.

Lipid nanoparticles help CAR T cells melt pancreatic cancer barriers

Often diagnosed when surgery is no longer an option, pancreatic cancer is one of the most difficult cancers to treat and has one of the lowest rates of survival among major malignancies.

Gene signature maps cholangiocarcinoma subtypes for precision treatment

Intrahepatic cholangiocarcinoma (iCCA), the second most common primary liver cancer after hepatocellular carcinoma, remains one of the most challenging malignancies to treat due to its highly concealed and heterogeneous nature.

Excessive RNA editing enzyme alters brain circuit formation in Down syndrome

A collaborative research study co-led by scientists at the Icahn School of Medicine at Mount Sinai and the Liber Institute for Brain Development has for the first time identified a biological process that may help explain how the brain develops differently in people with Down syndrome.

DNASE1L2 identified as a dynamic biomarker for TB progression

Tuberculosis (TB) remains one of the world's most serious public health threats, with approximately one-quarter of the global population infected with Mycobacterium tuberculosis. While most infections remain latent (LTBI), individuals with LTBI are at risk of progressing to active TB and potentially becoming new sources of transmission.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

Study proposes genetic basis for autism’s strong sex bias

Autism has a significant and enduring sex bias, with roughly four boys diagnosed for every girl. For many years, experts have believed this disparity arises primarily from diagnostic inequities because much of autism research - and the screening tools that grew out of it - has historically focused on boys, effectively setting a male standard for what autism "looks like."

Alcohol impacts gene expression differently across brain regions

Erica Periandri and Gabor Egervari, from Washington University in St. Louis, led a study to explore how alcohol exposure in male mice influences gene expression and mechanisms that regulate gene function-or epigenetics.

Artemin identified as marker and target in feline osteoarthritis

By comparing osteoarthritis pain pathways known to be active in dogs and humans to those in cats with degenerative joint disease (DJD), researchers found that elevation of a particular molecule, artemin, could serve as a marker of disease (and possibly pain) as well as a potential therapeutic target.
