The susceptibility of German shepherds to chronic diarrhoea is not due to a failure of transcription of
key genes encoding molecules involved in mucosal IgA secretion In collaboration with scientists at the University of Bristol, UK, WALTHAM investigated a potential cause of the susceptibility of German shepherd dogs to chronic diarrhoea (Peters et al. 2005).
One
key gene encodes the making of a receptor called TREM2, a docking site for molecules on the surface of microglia and other innate immune cells.

Biologists now know that the genome sequence holds only a small part of the answer, and that
key elements of development and disease are controlled by the epigenome — a set of chemical modifications, not
encoded in DNA, that orchestrate how and when
genes are expressed.
The second
gene, TNFRSF6B,
encodes a receptor related to those that bind tumor necrosis factor (TNF)-- a
key chemical signal for triggering inflammation in IBD as well as in patients with other autoimmune disorders such as rheumatoid arthritis and psoriasis.
They found what they were looking for on the CNGA3
gene, which
encodes a cyclic nucleotide channel and plays a
key role in transducing visual signals.
But a new report published today in Current Biology reveals that

genes that we think of as being silent actually
encode very
key functional information.»
In rice, Oryza sativa HOMEOBOX1, a
key regulator of meristem maintenance similar to kn1 from maize, controls local BR accumulation by directly targeting and upregulating
genes encoding BR catabolism and conjugation enzymes (Tsuda et al., 2014).
HIBM is caused by mutations in the
gene encoding the
key enzyme in sialic acid synthesis, UDP - GlcNAc 2 - epimerase / ManNAc kinase, which in turn leads to sialic acid deficiency.
