Effects Of Nnos Inhibitors On Melanoma-Induced Immunosuppression, Kate Alison Lozada

Pharmaceutical Sciences (MS) Theses

The incidence of cutaneous melanoma (CM) rises despite advances in immunotherapy and targeted therapy. Studies have shown that interferon-gamma (IFN-γ), a pro-tumorigenic cytokine in CM, induces the expression of programmed death-ligand 1 (PD-L1), leading to the escape of melanoma cells from immunosurveillance. Our previous study suggests that neuronal nitric oxide synthase (nNOS)-mediated nitric oxide (NO) signaling is crucial for melanoma progression and forms a mechanistic rationale behind nNOS inhibition as a novel treatment strategy for CM. An additional study demonstrated that IFN-γ interacts with nNOS signaling in melanoma and novel nNOS inhibitors (nNOSi) effectively diminished the induction of PD-L1 post …

Cyclic And Linear Cell-Penetarating Peptides Composed Of Tryptophan (Ww) And Arginine (Rr) Residues As Molecular Transporters, Lois Kim

Pharmaceutical Sciences (MS) Theses

The cell membrane has polar and negative charged characteristics and separates the inside of cells from the outside environment, and only allows small molecules to go into the cell to protect them from toxic substances. However, cell membrane characteristics make it difficult for polar and negatively-charged molecules to interact and penetrate the membrane. The delivery of cell impermeable compounds, such as phosphopeptides and siRNA, across the cell membrane remains a challenge. Previous studies in Dr. Parang’s laboratory have shown that cyclic peptides composed of tryptophan (W) and arginine (R) amino acids [WR]₅ have higher cellular uptake than the corresponding …

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

Pharmaceutical Sciences (PhD) Dissertations

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 …

Channelopathy Of Small- And Intermediate-Conductance Ca2+-Activated K+ Channels, Young-Woo Nam, Miles Downey, Mohammad Asikur Rahman, Meng Cui, Miao Zhang

Pharmacy Faculty Articles and Research

Small- and intermediate-conductance Ca²⁺-activated K⁺ (K_Ca2.x/K_Ca3.1 also called SK/IK) channels are gated exclusively by intracellular Ca²⁺. The Ca²⁺ binding protein calmodulin confers sub-micromolar Ca²⁺ sensitivity to the channel-calmodulin complex. The calmodulin C-lobe is constitutively associated with the proximal C-terminus of the channel. Interactions between calmodulin N-lobe and the channel S4-S5 linker are Ca²⁺-dependent, which subsequently trigger conformational changes in the channel pore and open the gate. KCNN genes encode four subtypes, including KCNN1 for K_Ca2.1 (SK1), KCNN2 for K_Ca2.2 (SK2), KCNN3 for K …

Rarick, Surya M. Nauli, Sean P. Palacek, Ramani Ramchandran

Pharmacy Faculty Articles and Research

In the developing vasculature, cilia, microtubule-based organelles that project from the apical surface of endothelial cells (ECs), have been identified to function cell autonomously to promote vascular integrity and prevent hemorrhage. To date, the underlying mechanisms of endothelial cilia formation (ciliogenesis) are not fully understood. Understanding these mechanisms is likely to open new avenues for targeting EC-cilia to promote vascular stability. Here, we hypothesized that brain ECs ciliogenesis and the underlying mechanisms that control this process are critical for brain vascular stability. To investigate this hypothesis, we utilized multiple approaches including developmental zebrafish model system and primary cell culture systems. …

Pharmacy Faculty Articles and Research

Brain microvascular endothelial cells, forming the anatomical site of the blood-brain barrier (BBB), are widely used as in vitro complements to in vivo BBB studies. Among the immortalized cells used as in vitro BBB models, the murine-derived bEnd.3 cells offer culturing consistency and low cost and are well characterized for functional and transport assays, but result in low transendothelial electrical resistance (TEER). Human-induced pluripotent stem cells differentiated into brain microvascular endothelial cells (ihBMECs) have superior barrier properties, but the process of differentiation is time-consuming and can result in mixed endothelial-epithelial gene expression. Here we performed a side-by-side comparison of the …
