Identifying A Glucocorticoid-Activated Gpcr That Rapidly And Non-Genomically Increases Camp Levels In Mammalian Cells, Francisco Nunez

Glucocorticoids (GCs) are steroid hormones that regulate diverse physiological processes. Synthetic versions of GCs are commonly used to treat inflammatory diseases such as asthma by modulating gene expression to suppressing several inflammatory activities. However, it is estimated that 5-10% of asthmatics are unresponsive to GCs, which may be explained by receptor desensitization and/or the presence of a neutrophilic endotype. One understudied phenomenon of GCs is their ability to induce rapid, non-genomic actions. For example, GCs can acutely modulate calcium concentrations levels, induce smooth muscle relaxation and modulate nitric oxide synthase activity, within minutes and sometimes seconds, which is too rapid …

Retinal fibrosis is detrimental to vision. Retinal pigment epithelial (RPE) cells contribute to several retinal fibrotic diseases. Upon exposure to TGF-β, a key fibrotic cytokine, RPE cells trans-differentiate to myofibroblasts marked by the integration of α-SMA fibers into F-actin stress fibers, which confer strong contractility. Myofibroblasts produce and contract the collagen-rich fibrotic scar and disrupt retinal architecture. In this study, we investigated the in vitro effects of the putative endocannabinoid compound N-oleoyl dopamine (OLDA) on TGF-β2 induced porcine RPE cell contraction and α-SMA expression. Using an in vitro collagen matrix contraction assay, we found that OLDA inhibited TGF-β2 induced contraction …
Efforts To Increase The Ketamine-Like Activity Of The Rapid-Acting Antidepressant Ro-25-6981 (Mi-4) By Increasing Ampa Potentiation, Nathan Heger
Annual Research Symposium
The small molecule ketamine has generated much interest due to its rapid antidepressant effects. Despite having a rapid onset, ketamine has poor bioavailability, short duration of action, toxicities with long-term use, and a high potential for abuse. The molecule MI-4 (RO 25-6981) has also been shown to have both a rapid and sustained antidepressant effect. Most of the research into the mechanism of the rapid onset of MI-4 and ketamine has focused on their interaction with the NMDA receptor in addition to some monoamine transporters. Some recent publications have shown a significant role of AMPA receptors in the ketamine antidepressant …
Effect Of Rehmannia Glutinosa Libosch Extract On Proliferation And Cardiogenic Pre-Differentiation Of Human Mesenchymal Stem Cells, Huu Dat Nguyen, Len Ho Thi, Xuan Bach Ho, Van Anh Cao, Duy Minh Le Hoang
Effect Of Rehmannia Glutinosa Libosch Extract On Proliferation And Cardiogenic Pre-Differentiation Of Human Mesenchymal Stem Cells, Huu Dat Nguyen, Len Ho Thi, Xuan Bach Ho, Van Anh Cao, Duy Minh Le Hoang
BioMedicine
Background: Vietnamese medicine tried and tested certain bioactive compounds from plants to increase the rate of tissue immunomodulation, regeneration, and differentiation. Although there are many research papers discovered about phytochemicals of Rehmannia glutinosa Libosch and differentiation induction potential of some substances purified from this herbal, it finds difficult to seek research that investigated the effect of Rehmannia glutinosa Libosch extract on proliferation and cardiogenic differentiation of mesenchymal stem cells, even though it has commonly been used for a long time because of its function as a restorative and as a critical role in cardiovascular treatment in traditional.

Repurposing Metformin And Antifolates For The Treatment Of Hepatocellular Carcinoma, Sherouk Mohamed Tawfik
Repurposing Metformin And Antifolates For The Treatment Of Hepatocellular Carcinoma, Sherouk Mohamed Tawfik
Theses and Dissertations
Hepatocellular carcinoma (HCC), one of the most prevalent types of cancers worldwide, continues to maintain high levels of resistance to standard therapy. As clinical data revealed poor response rates, the need for developing new methods has increased to improve the overall wellbeing of patients with HCC. Due to its safety, wide availability and previously reported anti-cancer effects, metformin (MET) serves to be a possible therapeutic agent when combined with other well-known anti-cancer agents. The aim of this study was to investigate the potential anti-cancer effects of MET, an anti-diabetic agent, when combined with two antifolate drugs: trimethoprim (TMP) or methotrexate …

Thyroid Hormone Receptor Beta Inhibits Pi3k Signaling And Glycogen Metabolism In Anaplastic Thyroid Cancer, Cole Davidson
Graduate College Dissertations and Theses
Thyroid cancer is the most common endocrine malignancy, and the global incidence has increased rapidly over the past few decades. While differentiated thyroid cancers often respond to standard therapies, there are no durable long-term treatment options for anaplastic thyroid cancer (ATC). The limited treatment options highlight a need for a deeper understanding of the molecular signaling in these aggressive tumors for development of more effective therapies.Non-steroidal nuclear receptors, such as thyroid hormone receptors (TRs), are an emerging class of therapeutic targets and tumor suppressors in thyroid and other cancers.Loss of expression of the tumor suppressor thyroid hormone receptor beta (TRβ) …
