Our project goals include: validation of predicted upstream regulators of WWC1/ KIBRA expression and identification of novel regulators via Chip-Seq and ATAC-seq analyses, define the biomechanical sequelae of KIBRA-mediated podocyte structural disruption, investigate downstream KIBRA non-canonical regulation of TEAD 1-4 and the effects of LATS kinase depletion in vitro and in vivo, and test whether novel small molecule LATS inhibitors and TEAD agonists can reverse or mitigate hyperglycemia-mediated podocyte injury in vitro and diabetic kidney disease in BTBR ob/ob mice.Compensation StatementThe Mount Sinai Health System (MSHS) provides a salary range to comply with the New York City Law on Salary Transparency in Job Advertisements.

However, little is known about the regulation of WWC1 /KIBRA expression, and therapeutic implications for KIBRA upregulation in FSGS and diabetic nephropathy remain unclear. Additionally, our preliminary data support non-canonical direct KIBRA downstream regulation of transcription factors TEAD 1-4. The objectives of this project are to define the regulators of WWC1 /KIBRA expression and function in podocytes, test non-canonical KIBRA-TEAD signaling, and to target LATS and TEAD as novel therapeutic strategies for KIBRA-mediated and diabetic podocyte injury. Based on our preliminary RNAseq analysis, our central hypothesis is that in podocytes, WWC1/KIBRA function in podocytes is repressed by the micro-RNA 200 family and regulated by transcription factors such as SOX4. In addition to canonical KIBRA regulation of LATS/YAP, KIBRA non-canonically directly suppresses TEAD 1-4 expression. Together, these downstream signaling events disrupt podocyte structural integrity and podocyte-glomerular basement membrane (GBM) adhesion, thereby promoting glomerular disease progression. The rationale for the proposed research is that testing novel regulators of KIBRA, non-canonical KIBRA signaling, and both novel canonical and non-canonical therapeutic approaches will significantly increase understanding of the mechanisms underlying glomerular disease progression and advance the quest for new selective treatments.Technical Duties: (include any protocols)
