Project description:Cardiac aging is a major risk factor for cardiovascular diseases, yet the underlying molecular mechanisms remain poorly understood. In this study, we employed a multi-omics approach combining single-nucleus RNA-seq, ATAC-seq, and reduced representation bisulfite sequencing (RRBS) to comprehensively characterize the cellular and molecular landscape of cardiomyocyte (CM) aging in mice.

Project description:Mitochondria are paramount to the metabolism and survival of cardiomyocytes. Here we show that Mitochondrial Fission Process 1 (MTFP1) is essential for cardiac structure and function. Constitutive knockout of cardiomyocyte MTFP1 in mice resulted in adult-onset dilated cardiomyopathy (DCM) characterized by sterile inflammation and cardiac fibrosis that progressed to heart failure and middle-aged death. Failing hearts from cardiomyocyte-restricted knockout mice displayed a general decline in mitochondrial gene expression and oxidative phosphorylation (OXPHOS) activity. Pre-DCM, we observed no defects in mitochondrial morphology, content, gene expression, OXPHOS assembly nor phosphorylation dependent respiration. However, knockout cardiac mitochondria displayed reduced membrane potential and increased non-phosphorylation dependent respiration, which could be rescued by pharmacological inhibition of the adenine nucleotide translocase ANT. Primary cardiomyocytes from pre-symptomatic knockout mice exhibited normal excitation-contraction coupling but increased sensitivity to programmed cell death (PCD), which was accompanied by an opening of the mitochondrial permeability transition pore (mPTP). Intriguingly, mouse embryonic fibroblasts deleted for Mtfp1 recapitulated PCD sensitivity and mPTP opening, both of which could be rescued by pharmacological or genetic inhibition of the mPTP regulator Cyclophilin D. Collectively, our data demonstrate that contrary to previous in vitro studies, the loss of the MTFP1 promotes mitochondrial uncoupling and increases cell death sensitivity, causally mediating pathogenic cardiac remodeling.

Project description:We report here the deep sequencing of the mRNA from peritoneal exudate cells (macrophages) purified from wildtype or Ptpn1 (PTP1B) knockout mice, either treated or untreated with IL-10. In periotenal macrophages IL-10 activates the transcription factor STAT3 to execute and anti-inflammatory gene expression programme. The tyrosine phosphatase PTPN1 targets STAT3 for dephosphorylation and leads to the deactivation of STAT3. In this study we examined the role of PTP1B in controlling the normal homeostatic level phosphorylation of STAT3 by comparing the IL-10/STAT3-mediated anti-inflammatory gene expression programme. We find that loss of PTP1B leads to an up-regulation of the activity of STAT3, both at the level of phosphorylation and also in enhanced expression of anti-inflammatory gene products.

Project description:In these experiments, we aimed to investigate the role of cardiomyocyte-specific deletion of the G-quadruplex resolvase Dhx36 in heart development and cardiomyocyte differentiation. To achieve this, we conducted multi-omics analysis using single-nuclei RNA sequencing (RNA-seq) and ATAC sequencing (ATAC-seq) on hearts from postnatal day 7 (PD7) wild-type (WT) and Dhx36 conditional knockout (cKO) mice. Our findings reveal that Dhx36 plays a critical role in the development of the cardiac conduction system (CCS) and in the differentiation of both CCS and working cardiomyocytes

Project description:Many patients have cancers that have increased activity of a protein called STAT3 that contributes critically to the development and growth of their cancer. Despite our knowledge of STAT3’s importance to cancer, scientists and doctors have not developed a drug that targets it and that patients can take to treat their cancer more effectively than treatments that are now available. Tvardi Therapeutics, Incorporated has developed a compound, TTI-101, which can be given by mouth and acts as a direct inhibitor of STAT3. Administration of TTI-101 to mice demonstrated that it blocked growth of cancers of the breast, head and neck, lung, and liver and it was safe when administered at high doses to mice, rats, and dogs. In this application, Tvardi is proposing to further develop TTI-101 for treatment of solid tumors for which the prognosis is dismal. The investigators will determine how safe it is when administered to patients with cancer, determine whether an adequate dose can be administered to patients with cancer that will block STAT3 in their cancer, and determine whether treatment with TTI-101 leads to reduced growth of their cancer.
