"Tribbles" Protein Implicated in Leukemia

... several groups shows that Tribbles functions as a scaffold to bring together a complex that mediates protein degradation. Protein degradation is required for normal cellular function; however, data from the Pear lab suggests that mistakes in the expression of the Tribbles gene may lead to degradation of prot...

Stem cells in regeneration of breast tissue in Cancer patients
