- Description:
- Cell-based therapies are an exciting frontier in medicine. This field is built on a simple premise—cells can be engineered to recognize and treat various human diseases. The paradigm of cell-based therapy uses biosensors to interrogate a cell’s environment and distinguish disease from health, intracellular signaling pathways and genetic circuitry to...

Role of Plasminogen Activator Inhibitor-1 (PAI-1) in Endothelial Senescence and Cardiovascular Aging
- Description:
- Plasminogen activator inhibitor-1 (PAI-1) is an essential mediator of senescence and a potential therapeutic target for preventing aging-related pathologies. Cellular Senescence is associated with organismal aging and related pathologies. In our study, we investigate the efficacies of PAI-1 inhibitors in both in vitro and in vivo models of homocysteine...

- Description:
- The formation of neuronal inclusions is one of the hallmarks of neurodegenerative diseases. These structures are composed of aggregated proteins, molecular chaperones, and components of the ubiquitin-proteasome system (UPS). Co-localization of aggregated proteins with cell-homeostasis maintaining machinery indicates that the cell may be failing in an attempt to clear these...

- Some of the oldest drugs targeting metabolism are the antifolates such as aminopterin and methotrexate (MTX). MTX started being used in the 1950s to treat rheumatoid arthritis. Aminopterin and MTX both target one carbon metabolism and inhibit proliferation of cells. MTX was a potent inhibitor of inflammation, because it prevented...

- Description:
- Eukaryotic genomes are organized into chromatin, which acts to regulate access to the organism’s genetic material. A large and diverse class of proteins, known as chromatin modifiers and remodelers, are responsible for regulating the composition and structure of chromatin by monitoring nucleosomes. Chromatin remodelers are involved in multiple cellular processes,...

- Gold nanoparticles (AuNPs) display unique characteristics compared to their macro-counterparts that are dependent on shape, size, and attached surface molecules. Methods have been developed to precisely control both size and shape of AuNPs for specific applications. The biocompatibility, plasmonic properties, and ease of functionalization with thiolated molecules, make gold nanoparticles...

- Description:
- The product of hexokinase (HK) enzymes, glucose-6-phosphate, can be metabolized through glycolysis or directed to alternative pathways, such as the pentose phosphate pathway (PPP) to generate anabolic intermediates. HK1 contains an N-terminal domain that permits mitochondrial binding, but its physiologic significance remains unclear. We generated mice lacking the HK1 mitochondrial-binding...

- Regulatory T (Treg) cells are required to control immune responses and maintain homeostasis, but are a significant barrier to antitumor immunity. Conversely, Treg instability, characterized by loss of the master transcription factor Foxp3 and acquisition of proinflammatory properties, can promote autoimmunity and/or facilitate more effective tumor immunity. A comprehensive understanding...

- Androgen receptor pathway inhibitors are the mainstay treatment for advanced prostate cancer, but resistance is common. Here, we used a CRISPR activation screen to identify genes that promote enzalutamide resistance in the metastatic castration-sensitive prostate cancer cell line LNCaP. We found that activation of the TGF-β target gene, PRRX2, promoted...
