What happens to your genes when you smoke a cigarette?

A groundbreaking study published in BMC Medical Genomics found significant changes in gene expression due to cigarette smoke exposure. The research, involving 1,240 individuals, identified over 323 unique genes whose expression levels were correlated with smoking behavior, revealing a sobering link between smoking and gene expression.

Even oysters pay taxes

A new study proposes that slow-growing animals waste energy in two ways, making too much protein and then discarding excess. Fast-growing oysters, on the other hand, are more efficient at protein production, according to USC marine biologists.

Gene discovered for newly recognized disease in Amish children

Researchers have discovered a gene linked to a newly recognized multisystem autoimmune disorder affecting Amish children, characterized by chronic diarrhea, enlarged organs, and developmental delays. The ITCH gene plays a crucial role in regulating the immune system, and identifying it may lead to effective treatment for these children.

There may be a 'party' in your genes

A recent study published in Political Research Quarterly found that genetics may contribute to an individual's political party identification, challenging the long-held assumption that it is solely shaped by socialization factors. The study used quantitative genetic models to examine the sources of party identification and intensity.

Plasma levels of GGT and ALB and their genetic correlations with cardiovascular risk factors

This study found that variations in plasma glutamyl transferase (GGT) and albumin (ALB) levels are genetically influenced and correlate with cardiovascular disease risk factors. The researchers identified chromosomal regions containing genes that affect GGT and ALB variation, which may also influence cardiovascular health.

A yeast cancer model for mapping cancer genes

Researchers have developed a yeast model to identify genes that contribute to cancer growth. The study found that point mutations in just a few genetic loci are responsible for the faster growth of cells, rather than aneuploidy. This discovery could help guide the search for new cancer genes in humans.

New breast cancer-promoting gene identified

A new gene, RCP, has been identified as a potential breast cancer-promoting gene, with overexpression causing tumor cell characteristics and metastasis. Targeting RCP may provide a way to inhibit the known tumor-promoting pathway through activation of the RAS signaling pathway.

Gene hunters target child kidney failure

Researchers have identified a potential genetic link to vesicoureteric reflux (VUR), a common cause of urinary tract infections and kidney failure in children. The study found that the VUR susceptibility gene is located on chromosome 12 and may be inherited in an autosomal recessive fashion.

Study identifies genes that protect against aging

Researchers at the University of Liverpool have developed a new method to identify genes that help protect the body from age-related changes. The study analyzed over five million gene measurements across multiple tissue types in animals and humans, highlighting key biological mechanisms that allow the body to adapt to aging.
