... with small effects. This is true for many of the QTLs identified for autoimmune phenotypes. Therefore, we developed two novel strategies to dissect a complex locus; The partial advanced intercross (PAI) strategy, with which we recently found the Cia5 region to consist of three loci, Cia5, Cia21 and ...

Article On the Complexity of Chloroplast RNA

... There may be multiple reasons for the remarkable complexity of chloroplast RNA metabolism. One is the need for regulation in response to developmental or environmental changes, in coordination with nuclear gene expression. An example is provided in Chlamydomonas by two proteins required for petA exp ...

However, in the rat and mouse the expression of the HRK transcript is much more restricted and HRK is detected in the brain but not the spleen, thymus, ...
The importance of having two X chromosomes - Neuroscience
The importance of having two X chromosomes - Neuroscience

... Because X inactivation is a random process in somatic tissues derived from the embryonic epiblast, each XX cell expresses most gene variants and parental imprints from only one of the two X chromosomes. Adult XX tissues and individuals are therefore mosaics of cells that exhibit the effects of eithe ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
