Potential Role Of The Large Protein Titin In The Development Of Heart Failure, Mary M. Prickett
Potential Role Of The Large Protein Titin In The Development Of Heart Failure, Mary M. Prickett
Senior Theses
I will be exploring the impact of the large protein Titin on heart failure with a preserved ejection fraction (HFpEF). It was hypothesized that myocardial Titin plays a significant role in the progression of HFpEF through isoform, N2BA and N2B, changes. It was hypothesized that an increase in the quantity of N2B Titin, less compliant, and a decrease in N2BA Titin, more compliant, will be observed as HF progresses, contributing to an increase in passive stiffness involved in heart contraction. I will cover a detailed report on the role of Titin in HFpEF and propose research methods to explore further.

BACKGROUND: Glucagon-like peptide-1 (GLP-1) induces diuresis and natriuresis. Previously we have shown that GLP-1 activates afferent renal nerve to increase efferent renal sympathetic nerve activity that negates the diuresis and natriuresis as a negative feedback mechanism in normal rats. However, renal effects of GLP-1 in heart failure (HF) has not been elucidated. The present study was designed to assess GLP-1-induced diuresis and natriuresis in rats with HF and its interactions with renal nerve activity.
METHODS: HF was induced in rats by coronary artery ligation. The direct recording of afferent renal nerve activity (ARNA) with intrapelvic injection of GLP-1 and total …
