Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Understanding how maternal age impacts offspring health across different species

In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation.

Sprint exercise sends a very different molecular signal through the body

Sprint-interval exercise triggers a much larger and faster shift in circulating proteins and metabolites than moderate-intensity exercise, revealing distinct patterns of predicted communication between organs. The findings suggest that exercise intensity shapes systemic molecular signaling, with skeletal muscle and adipose tissue emerging as potential source and target tissues linked to cardiometabolic health.

Youth-associated protein reverses age-related microglial changes in mice

Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells.

PolyU develops AI Virtual Patient Simulation System for precision cancer care

A research team at The Hong Kong Polytechnic University (PolyU) has developed a patient-centric "Artificial Intelligence (AI) Virtual Patient Simulation System", overcoming the limitations of conventional static diagnosis.

AI-based "tissue clocks" measure the biological age of human organs

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

Opening the black box of biological aging clocks

What do "epigenetic clocks" actually measure? These lab tests have become popular tools for studying biological aging, or how the body's cellular function changes at a faster or slower rate than expected.

Salk scientists use DNA origami to track molecular movements

Scientists often describe life as a series of chemical reactions. Pallav Kosuri, PhD, describes life as movement. Chemical reactions are how you drive the movement of atoms, proteins, cells, and bodies-without movement, there is no life.

Aging clock analysis identifies key genes in opioid dependence

A new research paper was published in Volume 18 of Aging on July 27, 2026, titled "Transcriptomic aging clock analysis identifies key genes in opioid dependence."

Molecular mapping reveals hidden cellular programs in heart transplant rejection

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

New computational tool identifies hidden genes driving asthma

Researchers at Columbia University Mailman School of Public Health, in collaboration with investigators at the University of Chicago, have developed a new computational framework that helps scientists identify genes that play central roles in diseases such as asthma but are often overlooked by existing genetic analysis methods.

Scientists identify parasite-specific protein linked to chronic Toxoplasma infections

Toxoplasma gondii, or Toxoplasma, is a parasite that infects hundreds of millions of people around the world.

Early-life stress rewires brain epigenetics to heighten sensitivity to future stress

. Early-life stress increased SETD7 and H3K4me1 in the ventral tegmental area of mice, creating an epigenetically primed state that heightened later transcriptional, neuronal, and behavioral responses to stress. Reducing Setd7 during development lowered H3K4me1 and weakened these stress-sensitizing effects, identifying a mechanism that may help explain how early adversity leaves lasting biological effects.

Scientists create single-cell atlas of spinal neurons involved in motor coordination

Scientists at St. Jude Children's Research Hospital created a single-cell atlas of a key class of spinal neurons involved in motor coordination. From that resource, they identified a small subgroup of interneurons associated with the speed of rhythmic movements such as walking.
