Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

Novel model system helps studying human ovarian biology

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

Study reveals how chloroplast ATP synthase regulates ATP production in organisms

ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called "chloroplast ATP synthase" (CFoCF1).

Scientists accelerate the development of pure genetic lines by inducing mutation

Iowa State University researchers may have solved a long-standing challenge associated with accelerated development of pure genetic lines.

Locating genes involved in the metabolism and distribution of human fat

Researchers from the University of Minnesota Medical School and the University of Chicago discovered data identifying “jumping genes”—associated with the distribution of fat in the abdomen—that are connected to a higher risk for health problems from obesity in women.

High diversity in T-cell receptor genes explains diverse response to infections

Researchers from Karolinska Institutet have demonstrated that the genes that encode the T cell receptors change significantly between individuals and communities, which could help explain why people react differently to certain diseases.

New insights into genetics of sexually dimorphic fat distribution in humans

Obesity causes many health problems and worsens several chronic illnesses, including type 2 diabetes and cardiovascular disease, however, some obese people are more susceptible to complications than others.

New approach to better target cellular proteins

By studying how enzymes move from one membrane compartment to another inside a cell, scientists at the University of Illinois Chicago have figured out a way to better target cellular proteins, which play a role in many diseases.

Novel approach removes the barriers of lifesaving cancer genetic services

Genetic counseling and genetic testing for mutations in certain genes such as BRCA1 and BRCA2 genes -; can help people understand their risk of certain types of cancer that can run in families, and improve outcomes through prevention, early detection, and targeted treatments.

New method triggers and analyzes the dynamics of brain protein linked to Alzheimer’s

Scientists are not yet clear on how the tau protein changes from a benign protein essential for normal function in our brains into the toxic neurofibrillary tangles that are a signature of Alzheimer's and other neurodegenerative diseases.

Versatile molecular toolbox expands the scope of gene regulation

Rice University scientists have enlisted widely used cancer therapy systems to control gene expression in mammalian cells, a feat of synthetic biology that could change how diseases are treated.

Research provides insight into the regulation of heartbeats

UT Southwestern Medical Center researchers have mapped gene control elements in specialized cardiac cells responsible for coordinating heartbeats. The findings of the genome exploration study, published in The Journal of Clinical Investigation, provide insight into how heartbeats are regulated and could impact diagnosis and risk prediction for a variety of common arrhythmias.
