'Role of fibronectin in the biogenesis and function of microfibrils in vivo' - ANAT 396 Undergraduate Research Project Application Form

INSTRUCTIONS - PROFESSORS: Please print and review this form. Complete or correct the sections, as applicable, from "Supervisor's Name" to "Ethics, safety, and training". Please sign and date near the bottom ("Supervisor's signature").

INSTRUCTIONS - STUDENTS: You may receive this form by email, or you may download it after it has been posted here. Either way, print and review this form. Complete or correct the sections, from "Student's Name" to "Student's Level", and sign ("Student signature"). Ask your supervisor to sign her/his section near the bottom. Take it to the department* corresponding to the course number in Section A; this may or may not be your own department. (* EXCEPTIONS: For NSCI 396 and COGS 396, please bring it to the Interdisciplinary Programs Adviser in Dawson Hall.) Do not register for a '396' course on Minerva until you receive departmental permission. Have a discussion with your supervisor about time/work expectations, keeping in mind that this is a 3-credit course (roughly, 10 hours per week for 12 weeks). Remember that a '396' course is an elective.

INSTRUCTIONS - DEPARTMENTS: After the unit chair/director/designate approves (or not) this project, please notify student. If approved, please give student permission to register on Minerva, and send a copy of this form (with signatures) to the Office for Undergraduate Research in Science (either fax, or internal mail to Dawson Hall 408-A, or PDF scan + email).

Project title: Role of fibronectin in the biogenesis and function of microfibrils in vivo

Project description (50-100 words suggested): Fibrillins are protein components of connective tissue fibers called microfibrils, which are ubiquitously distributed in most tissues including cardiovascular and pulmonary tissues. Mutations in fibrillins give rise to a number of heritable connective tissue disorders summarized as fibrillinopathies. These include Marfan syndrome, acromelic dysplasias, dominant Weill-Marchesani syndrome, stiff skin syndrome and others, with a combined prevalence of ~1 in 3,000. Immense inter- and intra-familial variability is a common feature of all fibrillinopathies, suggesting that other gene products play modifying roles in the disease pathogenesis. Full appreciation of pathogenetic mechanisms resulting in fibrillinopathies requires detailed understanding of fibrillin and microfibril biogenesis and function. We have demonstrated in published cell culture studies that another extracellular protein, fibronectin (FN), acts as an organizer of microfibril formation and function. Based on this finding, modified interactions between FN and mutant fibrillin in patients could be associated with disease pathogenesis. In this project, we aim to determine the role of FN on the formation, homeostasis and function of microfibrils in vivo. Since FN null mice are early embryonic lethal, we generated a conditional and tamoxifen-inducible FN knockout mouse model. In this model, FN can be deleted in smooth muscle cells at any given time point by injection of tamoxifen. Preliminary results demonstrate disorganized blood vessel walls, and enlarged airspaces in the lung after tamoxifen-induced FN deletion. The student will work on the analysis of the phenotype of this mouse model. The student will inject mice with tamoxifen, perform genotyping using various PCR techniques, prepare tissues, perform histological and immunohistological analyses, extract proteins from tissues and quantify them by Western blotting. The student will further work on data analysis and interpretation.
