This $142,902 Project Grant award from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), under the Diabetes, Digestive, and Kidney Diseases Extramural Research program (CFDA 93.847), aims to uncover the mechanism by which the regulatory GTPase ARL13B drives polycystic kidney disease (PKD) pathogenesis. The research, led by Dr. Van Sciver at Emory University, will biochemically and genetically dissect ARL13B's interaction with three effector proteins - CDK1, ARL3,...

The University of Pittsburgh received a $198,750 Project Grant from the National Institute of Diabetes and Digestive and Kidney Diseases (CFDA 93.847) to develop a rapid, quantitative platform using yeast to classify how approximately 70 identified mutations in the polycystin-1 (PC1) protein disrupt channel activity with PC2. This research aims to provide new reagents and assays to the scientific and PKD (polycystic kidney disease) community to study the molecular defects of PC1 mutants. The...
This federal Project Grant award of $640,001.00 was provided by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) under the Diabetes, Digestive, and Kidney Diseases Extramural Research program (CFDA 93.847). The award, which runs from January 1, 2025 to November 30, 2028, supports research conducted by Yale University to explore the mechanisms by which the protein polycystin-1 (PC1) and its C-terminal fragments affect mitochondrial function and cellular energy...
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) awarded a $135,582 Project Grant (CFDA 93.847 - Diabetes, Digestive, and Kidney Diseases Extramural Research) to the University of Oklahoma Health Sciences Center to construct a single-cell atlas of mouse and human cells in autosomal dominant polycystic kidney disease (ADPKD). The project aims to understand how molecular and cellular pathways found in ADPKD patients correlate to mouse models, and to identify inter-...

This Project Grant award from the National Institute of Diabetes and Digestive and Kidney Diseases (CFDA 93.847 Diabetes, Digestive, and Kidney Diseases Extramural Research) provides $504,621 to The University of Texas Southwestern Medical Center to investigate intracellular cholesterol biosynthesis as a regulator of polycystic kidney disease (PKD) progression. The research aims to: 1) determine if reducing intracellular cholesterol by inhibiting de novo synthesis or uptake aggravates...

This Project Grant award from the National Institute of Diabetes and Digestive and Kidney Diseases (CFDA 93.847 - Diabetes, Digestive, and Kidney Diseases Extramural Research) aims to investigate the role of the CDKN1A (P21) protein in regulating cyst growth and development in polycystic kidney disease (PKD). The $587,212 award to the University of Alabama at Birmingham will fund a 4-year research project to determine how abnormal P21 expression contributes to cyst initiation and expansion in PKD1 and PKD2 genetic mutations. The project will utilize innovative mouse models to trace the fate of P21-expressing cells and directly test the importance of P21 regulation in the cystic disease process. The findings are expected to provide critical insights that could lead to new strategies for more effective management of PKD.
