Characterizing Changes In The Colonic Epithelium Of Lrig3 Null Mice, Natalie Pedicino
Characterizing Changes In The Colonic Epithelium Of Lrig3 Null Mice, Natalie Pedicino
Scripps Senior Theses
The lining of the colon, or colonic epithelium, is a very dynamic and highly regulated tissue in the human body. Colonic stem cells are a key component of this tissue, and they make up the stem cell niche, which is found at the base of the colonic crypt. Regeneration of the colonic epithelium, which occurs on a weekly basis, is a complex process, and proteins responsible for directing regeneration are still being discovered. Two critical regulatory proteins, Lrig1 and Lrig3, have been shown to modulate the EGFR pathway, a key signaling pathway for growth, differentiation, and regeneration. Data from the …

Developing A Gene Editing System To Study Haplodiploidy In The Jewel Wasp, Nasonia Vitripennis, Emily A. Muller
Scripps Senior Theses
Hymenopteran insects, which include all ants, bees and wasps, reproduce through a poorly understood form of reproduction known as haplodiploidy. A promising experimental system for understanding this developmental process is the jewel wasp, Nasonia vitripennis. A critical aspect of using Nasonia as a model is establishing an effective means for editing specific genes of interest so that their functions can be studied through genetic means. For my thesis research, I performed a pilot study of the gene editing method known as CRISPR in Nasonia. I targeted the single heterochromatin protein 1 (HP1) gene present in the Nasonia genome …
