The intestinal epithelium is highly proliferative and consists of crypt invaginations that house
stem cells and villus projections with differentiated cells. There exists a dynamic equilibrium
between proliferation, migration, differentiation, and senescence that is regulated by several
factors. Among these are RNA binding proteins (RBPs) that bind their targets in a both
context dependent and independent manner. RBP–RNA complexes act as rheostats by
regulating expression of RNAs both co-and post-transcriptionally. This is important …
The intestinal epithelium is highly proliferative and consists of crypt invaginations that house stem cells and villus projections with differentiated cells. There exists a dynamic equilibrium between proliferation, migration, differentiation, and senescence that is regulated by several factors. Among these are RNA binding proteins (RBPs) that bind their targets in a both context dependent and independent manner. RBP–RNA complexes act as rheostats by regulating expression of RNAs both co- and post-transcriptionally. This is important, especially in response to intestinal injury, to fuel regeneration. The manner in which these RBPs function in the intestine and their interactions with other pivotal pathways in colorectal cancer may provide a framework for new insights and potential therapeutic applications.
