Post-Translational Modification Regulates Heterogeneous Nuclear Ribonucleoprotein K Function During Axon Outgrowth In Xenopus Laevis, Erica J. Hutchins
Post-Translational Modification Regulates Heterogeneous Nuclear Ribonucleoprotein K Function During Axon Outgrowth In Xenopus Laevis, Erica J. Hutchins

The RNA-binding protein, heterogeneous nuclear ribonucleoprotein K (hnRNP K), is required for axon outgrowth. Its suppression in Xenopus embryos causes defects in the translation of mRNAs of multiple cytoskeletal genes. Studies in cell lines have established that hnRNP K shuttles between the nucleus and the cytoplasm to bind and regulate the fates of its target RNAs, from splicing to export and translation. At each step, hnRNP K is regulated through post-translational modifications that alter its nucleic acid and protein interactions, and subcellular localization. Precisely how this happens in developing neurons to coordinate cytoskeletal gene expression with the extracellular signals directing …

Translational biomedical research holds potential for the development of novel therapeutics for the treatment of injury, illness or disability. To better understand intrinsic cellular and molecular biology, human embryonic stem cells (hESCs) can be used as a tool. hESCs are pluripotent with the abilities to be held in a self-renewal state or become induced to a desired germ layer then to be later directed through differentiation.

Coordinated synthesis and assembly of the cytoskeletal network contribute significantly to morphological changes during axon outgrowth. Previous studies demonstrated that heterogeneous ribonucleoprotein K (hnRNP K), an RNA binding protein, binds to the 3'-untranslated regions of all neurofilament triplet subunits, the most abundant components of the axonal cytoskeleton. These findings raised the hypothesis that hnRNP K post-transcriptionally mediates the coordinated expression of axonal cytoskeletal components. In my thesis, I test this hypothesis during both axonal development and regeneration.
Rho Kinase Regulates Basement Membrane Dynamics To Coordinate Salivary Gland Branching Morphogenesis And Tissue Organization, William Patrick Daley
Rho Kinase Regulates Basement Membrane Dynamics To Coordinate Salivary Gland Branching Morphogenesis And Tissue Organization, William Patrick Daley

Branching morphogenesis is a developmental mechanism utilized by many organs, including the salivary gland, lung, kidney, and mammary gland, to increase the epithelial surface area for secretion or absorption. The embryonic submandibular salivary gland (SMG) is a classic model for studying tissue morphogenesis in three dimensions ex vivo. Salivary gland development requires distinct but overlapping processes: morphogenesis, the actual physical rearrangement of cells into complex three dimensional structures, and cytodifferentiation, the process by which these cells begin to take on their own specialized function. Polarization, or the organization of cells into a cohesive tissue structure, also occurs concurrently during organ …

Breast tumors arise from preinvasive lesions consisting of abnormal epithelial cells that accumulate within the mammary duct. However, the initiating steps and underlying pathways leading to the formation of these early stages of breast carcinoma, such as ductal carcinoma in situ (DCIS), is not fully understood.
