Fetal alcohol spectrum disorders (FASD) are a spectrum of developmental disorders caused by prenatal alcohol exposure. Neuronal loss or neurodegeneration in the central nervous system (CNS) is one of the most devastating features in FASD. It is imperative to delineate the underlying mechanisms to facilitate the treatment of FASD. Endoplasmic reticulum (ER) stress is a hallmark and an underlying mechanism of many neurodegenerative diseases, including ethanol-induced neurodegeneration. Mesencephalic astrocyte-derived neurotrophic factor (MANF) responds to ER stress and has been identified as a protein upregulated in response to ethanol exposure during the brain development. To investigate the role of MANF in …

Pharmacology and Toxicology Faculty Publications

Backgrounds/aims: Mesenchymal stromal cell-derived exosomes (MSC-EXs) could exert protective effects on recipient cells by transferring the contained microRNAs (miRs), and miR-132-3p is one of angiogenic miRs. However, whether the combination of MSC-EXs and miR-132-3p has better effects in ischemic cerebrovascular disease remains unknown. Methods: Mouse MSCs transfected with scrambler control or miR-132-3p mimics were used to generate MSC-EXs and miR-132-3p-overexpressed MSC-EXs (MSC-EXsmiR-132-3p). The effects of EXs on hypoxia/reoxygenation (H/R)-injured ECs in ROS generation, apoptosis, and barrier function were analyzed. The levels of RASA1, Ras, phosphorylations of PI3K, Akt and endothelial nitric oxide synthesis (eNOS), and tight junction proteins (Claudin-5 and …


Effects Of Alternative Chemotherapeutic Agents On Thyroid Cancer Cell Line Ml-1, Husref Rizvanovic May 2020

Effects Of Alternative Chemotherapeutic Agents On Thyroid Cancer Cell Line Ml-1, Husref Rizvanovic

MSU Graduate Theses

Though differentiated thyroid carcinomas have decent prognosis when detected early, radioactive iodine (RAI) resistant and advanced thyroid cancers are still difficult to treat with existing therapies. Better therapeutic agents are needed. Studies have shown that aggressive thyroid cancers (ML-1) express the extracellular matrix protein, matrix metalloproteinase (MMP-2). MMP-2 has been linked to metastasis and aggressiveness of several cancers and has been shown to play a crucial role in tumor invasion. Chlorotoxin is a selective MMP-2 receptor agonist, and Saporin is a well-known ribosome-inactivating protein used for anti-cancer treatment; however, these two agents have never been studied when conjugated together. I …


Cell-Free Dna Release During Programmed Cell Death In Kidney Ischemia Reperfusion Injury, Alexander Dionne Feb 2020

Cell-Free Dna Release During Programmed Cell Death In Kidney Ischemia Reperfusion Injury, Alexander Dionne

Electronic Thesis and Dissertation Repository

Transplantation is invariably associated with ischemia reperfusion injury (IRI) which causes organ dysfunction. IRI is also directly linked to several forms of programmed cell death including apoptosis and necroptosis, which increase kidney dysfunction, promote inflammation and may contribute to premature graft failure. The contribution of necroptosis and apoptosis following kidney IRI to cell-free DNA (cfDNA) generation and the potential of cfDNA to activate effectors such as NK cells involved in kidney IRI have not been defined. Our data indicate that necroptotic microvascular endothelial cells (MVECs) release considerably more cfDNA than apoptotic MVECs or untreated controls (p


The Effect Of The Senolytic Abt-263 On Androgen Deprivation-Induced Senescent Prostate Tumor Cells, So Min Lee Jan 2020

The Effect Of The Senolytic Abt-263 On Androgen Deprivation-Induced Senescent Prostate Tumor Cells, So Min Lee

Theses and Dissertations

Prostate cancer (PCa) is one of the leading causes of cancer-related deaths in men. Although standard treatments such as androgen deprivation therapies (ADT) and antiandrogens have increased survival for many patients, most men placed on these therapies will develop castration-resistant disease (CRPC). Previous studies have shown that these treatments have limited cytotoxicity and instead promote cell growth arrest. Our current work demonstrates that prostate tumor cells grown in the absence of androgens by using charcoal-stripped serum undergo senescence-mediated or senescent-like growth arrest, based on the cellular expression of senescence-associated-beta-galactosidase (SA-β-Gal). Our studies further suggest that this senescence is transient and …

Nebraska Center for Virology: Faculty Publications

We previously showed that rhesus macaques neonatally infected with simian immunodeficiency virus (SIV) do not develop SIV encephalitis (SIVE) and maintain low brain viral loads despite having similar plasma viral loads compared to SIV-infected adults. We hypothesize that differences in myeloid cell populations that are the known target of SIV and HIV in the brain contribute to the lack of neonatal susceptibility to lentivirus-induced encephalitis. Using immunohistochemistry and immunofluorescence microscopy, we examined the frontal cortices from uninfected and SIV-infected infant and adult macaques (n = 8/ea) as well as adults with SIVE (n = 4) to determine differences in myeloid …

Turkish Journal of Medical Sciences

The aim of this review is to summarize current studies on the relationship between melatonin and aging. Nowadays, age-related diseases come into prominence, and identifying age-related changes and developing proper therapeutic approaches are counted as some of the major issues regarding community health. Melatonin is the main hormone of the pineal gland. Melatonin is known to influence many biological processes in the body, including circadian rhythms, the immune system, and neuroendocrine and cardiovascular functions. Melatonin rhythms also reflect the biological process of aging. Aging is an extremely complex and multifactorial process. Melatonin levels decline considerably with aging and its decline …

Physiological And Pharmacological Roles Of Melatonin In The Pathophysiologicalcomponents Of Cellular Injury After Ischemic Stroke, Ertuğrul Kiliç, Berrak Çağlayan, Mustafa Caglar Beker Jan 2020

Physiological And Pharmacological Roles Of Melatonin In The Pathophysiologicalcomponents Of Cellular Injury After Ischemic Stroke, Ertuğrul Kiliç, Berrak Çağlayan, Mustafa Caglar Beker

Turkish Journal of Medical Sciences

Apart from its metabolic or physiological functions, melatonin has a potent cytoprotective activity in the physiological and pathological conditions. It is synthetized by the pineal gland and released into the blood circulation but particularly cerebrospinal fluid in a circadian manner. It can also easily diffuse through cellular membranes due its small size and lipophilic structure. Its cytoprotective activity has been linked to its potent free radical scavenger activity with the desirable characteristics of a clinically- reliable antioxidant. Melatonin detoxifies oxygen and nitrogen-based free radicals and oxidizing agents, including the highly toxic hydroxyl-and peroxynitrite radicals, initiating cellular damage. However, the cytoprotective …
