Targets And Functions Of The Microrna-200 Family In The Developing Skin And Hair Follicle, Jaimee Elizabeth Hoefert Jan 2018

Targets And Functions Of The Microrna-200 Family In The Developing Skin And Hair Follicle, Jaimee Elizabeth Hoefert

Molecular, Cellular, and Developmental Biology Graduate Theses & Dissertations

The microRNA-200 (miR-200) family is well known for preventing epithelial-to-mesenchymal transition in cancer. However, the targets and functions of this family in normal epithelial tissues remain unclear. This five-member microRNA (miRNA) family also presents a unique platform for studying miRNA-mediated regulation, as they share two nearly-identical seed sequences. The results presented within this dissertation establish a role for these miRNAs in governing hair follicle morphogenesis and fine-tuning cell specification by regulating cell adhesion, polarity, and signaling pathways. By directly ligating miRNAs to their targeted mRNA regions, numerous miR-200 family targets are identified, many of which are involved ...
