The circadian rhythm of glucocorticoids is regulated by a gating mechanism residing in the adrenal cortical clock

In mammals, including humans, a master clock in the brain and subordinate clocks found in organs throughout the body coordinate daily, or circadian, rhythms of behavior and physiology.

Discovery of mechanism that may explain post-transplant lymphoproliferative disorder

A serious form of cancer that occurs in some transplant patients may arise because cells that normally serve as scouts for the immune system become weakened, a new study suggests.

Atp7a determines a hierarchy of copper metabolism essential for notochord development

A new study reveals the timing of developmental events that critically depend on copper. While copper deficiency is rare in humans, the findings suggest that suboptimal copper metabolism might contribute to birth defects, according to the researchers.

DNA overwinds when stretched

Most of us are familiar with the winding staircase image of DNA, the repository of a biological cell's genetic information. But few of us realize just how tightly that famous double helix is wound.

New tool to study protein kinase A - linked to heart failure

Scientists studying heart cells have devised a new way to visualize and quantify the rise and fall in the activity of a key enzyme linked to heart failure.

Exercise important in reducing size of abdominal fat cells

Reducing the size of abdominal fat cells - which are a risk factor for diabetes and heart disease - takes more than cutting calories, according to new research from Wake Forest University Baptist Medical Center.

Gene amplification links growth controlling pathway from Drosophila to human cancers

Researchers at Harvard Medical School (HMS) and Massachusetts General Hospital (MGH) have discovered a new cancer-promoting role for a gene potentially involved in breast, liver, and other kinds of cancers.

AIDS drugs still work but TB a deadly addition to the virus

According to a new report, ten years after they were introduced in Europe and North America, HIV/AIDS drugs remain effective but many patients are not being put on them soon enough.

Leukemia gene changes genetic packaging

A signaling system involved in many forms of leukemia and lymphoma is more powerful than scientists have thought, exerting control over our genes by affecting whole swaths of chromosomes in global fashion.

For the first time, scientists watch neurons change in response to experience

Thanks to a new imaging system, researchers at MIT's Picower Institute for Learning and Memory have gotten an unprecedented look into how genes shape the brain in response to the environment.

Minimally invasive robotic surgery used to inject stem cells into damaged hearts

Researchers at the University of Minnesota were successful in using robotic surgery to deliver stem cell treatment to damaged heart tissue in pigs.

New research may solve problem of vessels re-closing after angioplasty

Through studying pigeons with genetic heart disease, researchers at Wake Forest University School of Medicine have discovered a clue about why some patients' heart vessels are prone to close back up after angioplasty.

Aggressive melanoma cells secrete Nodal - protein critical to embryo formation

A Northwestern University research group has discovered that aggressive melanoma cells secrete Nodal, a protein that is critical to proper embryo formation.

HIV virus can survive efforts to destroy it by hiding in the mucosal tissues of the intestine

UC Davis researchers have discovered that the human immunodeficiency virus, the virus that causes AIDS, is able to survive efforts to destroy it by hiding out in the mucosal tissues of the intestine.

DNA of human embryonic stem cells is chemically modified in a characteristic, predictable pattern

Embryonic stem cells are derived from embryos that are undergoing a period of intense cellular activity, including the chemical addition of methyl groups to specific DNA sequences in a process known as DNA methylation.
