ENCODE Project: Junking the Idea of Junk
DNA
by Jeremy Cherfas
The pilot study for the ENCODE Project, an encyclopedic study of
variation in the human genome, has already produced evidence that
supposedly non-coding regions of genetic material, previously
dubbed ‘junk DNA,’ actually possess complex properties
whose role in gene function and evolutionary conservation remains
to be elucidated.

In MicroRNA Research, Silence is Looking
Golden
by Jeremy Cherfas
Research into the strands of microRNA (miRNA) has clarified the
role that these molecules play in gene expression and other aspects
of cellular function. In particular, miRNA has been implicated in
diseases such as cancer, hepatitis, and diabetes. A research team
developed so-called ‘antagomirs’ to silence miRNA,
helping to elucidate miRNA’s role in cell differentiation and
other processes.

Tireless
Research Hints at Boost for Tuckered T Cells
by Jeremy Cherfas
A study of CD8 T cells of the immune system during infection has
indicated that blocking the action of certain proteins may prevent the
T cells from becoming exhausted and ineffective, raising hope for
treatment of such chronic infections as HIV and hepatitis.
