Cryptic transcription in mammalian stem cells linked to aging

Although visible signs of aging are usually unmistakable, unraveling what triggers them has been quite a challenge. Researchers at Baylor College of Medicine and collaborating institutions have discovered that a cellular ...

Gene expression mechanism may have immunity, cancer implications

Alternative polyadenylation (APA) is an RNA processing mechanism that regulates gene expression by generating different ends on RNA transcripts of the same gene. Though it affects more than half of human genes, the significance ...

Missed signals? A new way we vary from each other biologically

Genetics has made huge strides over the past 20 years, from the sequencing of the human genome to a growing understanding of factors that turn genes on and off, namely transcription factors and the DNA "enhancer" sequences ...

Scientists map genes controlling immune system 'brakes'

Unlike most T cells, which launch immune responses against foreign molecules, regulatory T cells are the peacekeepers of the human immune system, damping down inflammatory reactions when they're not needed. Now, researchers ...

A master regulator of kidney health?

End-stage kidney disease often begins with injury to podocytes. These highly specialized cells are a critical part of the glomeruli, clusters of capillaries that serve as the filtration units in our kidneys' tightly-packed ...
