The Effects Of 7,8-Dihydroxyflavone On Hippocampal Neurogenesis Following Traumatic Brain Injury, Mary K. Wurzelmann

Theses and Dissertations

Following traumatic brain injury (TBI), the hippocampus is particularly vulnerable to damage, and BDNF, an endogenous neurotrophin that activates the TrkB receptor, has been shown to play a key role in the brain’s neuroprotective response. Activation of the TrkB signaling pathway by BDNF in the CNS promotes cell survival and aids in cell growth. However, due to its inability to cross the blood brain barrier (BBB), the therapeutic advantages of BDNF treatment following TBI are limited. 7,8-Dihydroxyflavone (7,8-DHF) is a flavonoid that mimics the effects of BDNF, is a potent TrkB receptor agonist, and can successfully cross the BBB. Our …

Molecular Mechanisms Of Suberoylanilide Hydroxamic Acid In The Inhibition Of Tgf-Β1-Mediated Canine Corneal Fibrosis, Kristina M. Gronkiewicz, Elizabeth A. Giuliano, Ajay Sharma, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Objective—To investigate molecular mechanisms mediating anti-fibrotic effect of SAHA in the canine cornea using an in vitro model. We hypothesized that SAHA attenuates corneal fibrosis by modulating Smad-dependent and, to a lesser extent, Smad-independent signaling pathways activated by TGF-β1, as well as matrix metalloproteinase (MMP) activity.

Methods—Cultured canine corneal fibroblasts (CCF) were incubated in the presence/absence of TGF-β1 (5ng/ml) and SAHA (2.5μM) for 24hrs. Western blot analysis was used to quantify non-phosphorylated and phosphorylated isoforms of Smad2/3, p38 MAP kinase (MAPK), ERK1/2 and JNK1. Real-time PCR and zymography were utilized to quantify MMP1, MMP2, MMP8 and MMP9 mRNA expression and …

Pcsk9 Inhibitors: A Review Of The Efficacy, Safety And Current Literature Recommendations, Lacey L. Jandrin

Physician Assistant Scholarly Project Posters

Atherosclerotic cardiovascular disease is the leading cause of morbidity and mortality in developed counties. It is estimated that 60 million Americans have LDL-C levels > 160 mg/dl. Only about 1/3 of these patients meet treated LDL cholesterol goals of < 70 mg/dl indicating a need for greater control. High dose statins have been the mainstay in treatment of dyslipidemia, however, up to 20% of patients are statin intolerant indicating a need for secondary treatment strategies. This lead to the development of monoclonal antibodies to proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors. PCSK9 inhibitors result in decreased destruction of the low-density lipoprotein receptor (LDL-R) which leads to an increase in the transport of LDL-C to its destruction effectively reducing LDL-C levels in the blood. The purpose of this study is to analyze the literature available on the efficacy and safety of new PCSK9 inhibitors. The results of this literature review indicated that PCSK9 inhibitors effectively lowered LDL-C by an average of approximately 50%. The evidence reviewed by this analysis indicate that 70% of patients treated with PCSK9 inhibitors met LDL-C goals. The findings also indicate that the side effects associated with this new class of medications are comparable to current side effects seen with traditional cholesterol lowering agents. The largest side effect seen in up to 10% of patients were injection site reactions and did not require discontinuation of the medication. The results of this analysis indicate that PCSK9 inhibitors may be of benefit in patients who are statin intolerant, do not meet LDL-C goals on traditional statin therapy or have familial hypercholesterolemia. Education in use of injectables, cost and insurance coverage and dosing schedule are likely to be areas of continued research and may affect use of this new class of cholesterol lowering agents.

Role Of Sulfiredoxin Interacting Proteins In Lung Cancer Development, Hedy Chawsheen

Theses and Dissertations--Toxicology and Cancer Biology

Sulfiredoxin (Srx) is an antioxidant enzyme that can be induced by oxidative stress. It promotes oncogenic phenotypes of cell proliferation, colony formation, migration, and metastasis in lung, skin and colon cancers. Srx reduces the overoxidation of 2-cysteine peroxiredoxins in cells, in addition to its role of removing glutathione modification from several proteins. In this study, I explored additional physiological functions of Srx in lung cancer through studying its interacting proteins. Protein disulfide isomerase (PDI) family members, thioredoxin domain containing protein 5 (TXNDC5) and protein disulfide isomerase family A member 6 (PDIA6), were detected to interact with Srx. Therefore, I proposed …

The Effect Of Proanthocyanidin On Formaldehyde-Induced Toxicity In Rat Testes, Eni̇s Uluçam, Elvan Bakar

Turkish Journal of Medical Sciences

Background/aim: This study investigated the effect of proanthocyanidin (PA) against formaldehyde (FA)-induced lipid peroxidation damage and morphological changes in rat testes. Materials and methods: Twenty-one Wistar albino rats were randomized into 3 groups: control, FA, and FA + PA groups. Plasma and tissue malondialdehyde (MDA) and total sialic acid (TSA) levels were measured. Testes tissues were observed by light and electron microscopy. Results: TSA (plasma and tissue) levels decreased and MDA (plasma) significantly increased (P < 0.05) in rats treated with FA compared to the controls. Tissue MDA levels were not significantly different. Several necrotic changes were observed in testes tissues by light and electron microscopy. Disordering in epithelia of seminiferous tubules, vacuolization between germinal epithelium cells, and separated basement membranes were observed by light microscope. Immunopositivity in Leydig cells decreased in the FA group (P < 0.05). In the FA + PA group there were more immune Leydig cells reacting immune-positively than in the FA group (P < 0.05). Ultrastructurally, FA also caused disorganization and loss of mitochondrial cristae, and dilatation in endoplasmic reticulum in testes. Conclusion: The results suggest that PA has a protective effect on FA toxicity in testes.

Ilp-2 Modeling And Virtual Screening Of An Fda-Approved Library:A Possible Anticancer Therapy, Saeed Khalili, Hemn Mohammadpour, Mahideh Shokrollahi Barough, Parviz Kokhaei

Turkish Journal of Medical Sciences

Background/aim: The members of the inhibitors of apoptosis protein (IAP) family inhibit diverse components of the caspase signaling pathway, notably caspase 3, 7, and 9. ILP-2 (BIRC-8) is the most recently identified member of the IAPs, mainly interacting with caspase 9. This interaction would eventually lead to death resistance in the case of cancerous cells. Therefore, structural modeling of ILP-2 and finding applicable inhibitors of its interaction with caspase 9 are a compelling challenge. Materials and methods: Three main protein modeling approaches along with various model refinement measures were harnessed to achieve a reliable 3D model, using state-of-the-art software. Thereafter, …
