Possible Explanation for Human Diseases Caused by Defective Ribosomes

Ribosomes are essential for life, generating all of the proteins required for cells to grow. Mutations in some of the proteins that make ribosomes cause disorders characterized by bone marrow failure and anemia early in life, followed by elevated cancer risk in middle age. These disorders are generally called “ribosomopathies.”

This Longhorn Has Been Brought to You by DNA

In a set of two recent papers, Andy Ellington and his lab show how DNA can make pictures, but more importantly, that DNA circuits could someday be used to manufacture drugs or grow organs, such as a new heart.

Mammalian Body Cells Lack Ancient Viral Defense Mechanism, Find UT Scientists

Mammalian Body Cells Lack Ancient Viral Defense Mechanism, Find UT Scientists

A team led by Chris Sullivan, a professor of molecular biosciences at The University of Texas at Austin, has provided the first positive evidence that RNA interference (RNAi), a biological process in which small RNA molecules prevent genes from being expressed, does not play a role as an antiviral in most body, or “somatic,” cells in mammals.
