Astrocytes are the most numerous cells in the brain and play a critical role in maintaining homeostatic extracellular potassium ([K+]e). This process is mediated, in part, by a glial-specific, inwardly rectifying potassium channel, Kir4.1. Pharmacological inhibition, knock down, or complete knock out of this channel results in astrocytes with increased membrane resistance, depolarized resting membrane potential, and altered extracellular potassium dynamics. Subsequent to the dysregulation of [K+]e, Kir4.1 knockout (KO) animals suffer from ataxia, seizures, and early postnatal death. Interestingly, Kir4.1 has long been characterized as a seizure susceptibility gene. The importance of Kir4.1 is further underscored by recent studies …

New Mouse Models To Aid Studies Of The Role Of Primary Cilia In Limb Patterning And Bone Development, Amber Kathleen O'Connor

All ETDs from UAB

Hedgehog (Hh) signaling is required for many developmental processes, and causes several diseases and cancers. Described in chapter one below, vertebrate Hh sig-naling is dependent on the primary cilium (PC), a small organelle that extends from the surface of most mammalian cell types. A better understanding of how the PC modulates Hh signaling is important, as defects in the structure or function of PC result in severe human disorders termed the ciliopathies. For example, patients with Meckel-Gruber Syndrome have extra digits and neural tube defects, which are Hh both related pheno-types. In chapter two we sought to further understand the …

Phospho-Erk And Amyloid Beta: Targets Of Estrogen In The Brain, Thomas Reed Peavy

All ETDs from UAB

Estrogen replacement therapy (ERT) has been shown to improve memory function in menopausal women, but increases hormone sensitive cancers, prompting a more targeted investigation of estrogen's action in learning and memory to develop more targeted therapeutics. Estrogen improves performance on the novel object recognition task by increasing phosphorylation of extracellular signal-regulated kinase (pERK) within minutes in the hippocampus. Dr. Lori McMahon's lab showed that the improvement in novel object recognition can be seen 24 hours after subcutaneous injection of proestrous levels of estrogen (referred to as E24). Whether a corresponding increase in pERK occurs at the E24 time point had …

Characterization Of The Retina In The Alpha 7 Nicotinic Acetylcholine Receptor Knockout Mouse, Marci Lynn Smith

All ETDs from UAB

Acetylcholine receptors (AChRs) are involved in visual processing and are expressed by inner retinal neurons in all species studied to date (Keyser et al., 2000; Dmitrieva et al., 2007; Liu et al., 2009), but their distribution in the mouse retina remains unknown. Reductions in alpha 7 nicotinic AChRs (nAChRs) are thought to contribute to memory and visual deficits observed in Alzheimer's and schizophrenia (Coyle et al., 1983; Nordberg et al., 1999; Leonard et al., 2006). However, the alpha 7 nAChR knockout (KO) mouse has a mild phenotype (Paylor et al., 1998; Fernandes et al., 2006; Young et al., 2007; Origlia …

Effects Of Light Spectra And Uv Radiation In Relation To Dietary Carotenoids On The Sea Urchin Lytechinus Variegatus, James Christopher Taylor Jan 2013

Effects Of Light Spectra And Uv Radiation In Relation To Dietary Carotenoids On The Sea Urchin Lytechinus Variegatus, James Christopher Taylor

All ETDs from UAB

An important factor in the marketability of sea urchin gonad is color. A marketable color is suggested to be dependent upon the in vivo accumulation of red and yellow carotenoid pigments within the gonad. Carotenoids obtained through the diet can be modified in sea urchins, but the function of these carotenoids is unknown. We hypothesize that differential light exposure can affect carotenoid deposition and, as a consequence, gonad color in sea urchins. We performed two experiments to determine if light spectra affect gonad color of Lytechinus variegatus. In the first experiment, urchins were fed a formulated feed supplemented with or …

The Origin, Regulation, And Function Of Tbet In Effector Cd4 T Cells During Chronic Autoimmune Disease, Wen-I Yeh Jan 2013

The Origin, Regulation, And Function Of Tbet In Effector Cd4 T Cells During Chronic Autoimmune Disease, Wen-I Yeh

All ETDs from UAB

Multiple Sclerosis (MS) is an autoimmune disease resulting from aberrant immune cells causing demyelination. We utilize the well-studied mouse model, experimental autoimmune encephalomyelitis (EAE), to decipher the underlying pathogenesis of MS. Effector CD4 T-cells play a critical role during EAE because the disease is induced by adoptively transferring myelin-specific CD4 T-cells into naïve mice. Classically, effector CD4 T-cells have been divided into distinct subsets based on their functional properties: Th1 cells produce IFNγ, Th2 cells secrete IL-4, IL-5, and IL-13, Th17 cells make IL-17A, IL-17F, IL-21, and IL-22, and regulatory T cells produce IL-10. Th1 cells were originally identified as …

Regulation Of Stim1 By O-Glcnacylation In Cardiomyocytes, Xiaoyuan Zhu-Mauldin Jan 2013

Regulation Of Stim1 By O-Glcnacylation In Cardiomyocytes, Xiaoyuan Zhu-Mauldin

All ETDs from UAB

In non-excitable cells, STIM1 and Orai1 are the primary mediators of store-operated Ca2+ entry (SOCE); however little is known about their roles in cardiomyocyte Ca2+ handling. We have previously shown that acute increases in the levels of O-GlcNAcylation (the attachment of O-linked N- acetylglucosamine (O-GlcNAc) to target proteins) are cardioprotective through attenuating Ca2+-mediated injury and increased O-GlcNAcylation blunts SOCE in cardiomyocytes. Therefore, the goals here were to determine the regulation of STIM1 and STIM1-mediated SOCE by O-GlcNAcylation in cardiomyocytes. Immunohistochemical analysis demonstrated the co-localization of STIM1 with SERCA and RyR in adult cardiomyocytes. NRVMs were transfected with the eYFP-tagged STIM1 …

The Role Of Nr4a3 And Its Agonists In Skeletal Muscle Glucose Transport And Insulin Sensitivity, Qinglan Liu Jan 2013

The Role Of Nr4a3 And Its Agonists In Skeletal Muscle Glucose Transport And Insulin Sensitivity, Qinglan Liu

All ETDs from UAB

Insulin resistance plays a central role in the pathogenesis of Type 2 Diabetes (T2DM) and involves diminished stimulation of glucose transport in skeletal muscle. Improvements in insulin sensitivity are essential for both prevention and treatment of T2DM. However, the limitation of current medications highlights the need for alternative molecular regulators of insulin action and developing new insulin sensitizers. Our laboratory has initially identified roles for the orphan nuclear receptor NR4A3 in insulin-sensitization and stimulation of glucose transport. However, the cellular effect and downstream mechanisms of NR4A3 and its agonists (e.g. 6-mercaptopurine/6-MP) on insulin effector system in skeletal muscle remain unknown. …

Investigation Of Death Receptor-5 Mediated Apoptosis And Inhibition Of Wnt/Ss-Catenin Signaling In Basal-Like Breast Cancer Stem Cells, Angelina Ix-Ik' Londono-Joshi

All ETDs from UAB

Basal-like breast cancers (BLBC) display aggressive clinical behavior attributed to the presence of cancer stem cells (CSCs). TRA-8, a monoclonal antibody that binds specifically to TRAIL death receptor 5, preferentially induces apoptosis in BLBC subtype cells; however it is unknown if TRA-8 is also cytotoxic to the CSC population. Moreover, some BLBC cell lines are resistant to TRA-8, and overcoming resistance is critical for clinical translation of this therapy. One potential approach to overcome TRA- 8 resistance is to target the Wnt/ß-catenin pathway. LRP6 is a cell surface receptor that is an indispensable element of the Wnt/ß-catenin signaling pathway that …

Blood Pressure And Tobacco Exposure Among Rural Adolescents Ages 15-18, Luz Huntington-Moskos

All ETDs from UAB

High blood pressure is a prevalent precursor to cardiovascular disease. An estimated 3% of US adolescents have hypertension. In addition, prehypertension is predictive of hypertension in adolescents, with progression between these stages at approximately 7% per year. Tobacco use/exposure is strongly linked to cardiovascular risk and disease in adults. Further, rural communities have higher tobacco use prevalence and fewer community policies restricting tobacco use. Little is known about the effects of tobacco exposure on blood pressure and the mediating effects of inflammation (salivary C-reactive protein (CRP)) in rural adolescents. The purpose of this study is to determine the relationships between …

Universal Reading Processes Are Modulated By Language And Writing System, Charles A. Perfetti, Lindsay N. Harris Jan 2013

Universal Reading Processes Are Modulated By Language And Writing System, Charles A. Perfetti, Lindsay N. Harris

Faculty Articles, Papers, and Other Scholarship

The connections among language, writing system, and reading are part of what confronts a child in learning to read. We examine these connections in addressing how reading processes adapt to the variety of written language and how writing adapts to language. The first adaptation (reading to writing), as evidenced in behavioral and neuroscience data, is achieved through a universal constraint that language places on writing and through the tuning of reading procedures imposed by specific features of writing systems. Children acquire skill in reading through increasing specialization of procedures tuned to their writing system, while also acquiring more general (universal) …

Civil Non-State Actors In Peacekeeping And Peacebuilding In West Africa, Abu Bakarr Bah Jan 2013

Civil Non-State Actors In Peacekeeping And Peacebuilding In West Africa, Abu Bakarr Bah

Faculty Articles, Papers, and Other Scholarship

This paper advances the notion of civil non-state actors in peacekeeping and peacebuilding. Using Sierra Leone, Liberia, and Côte d’Ivoire as cases studies, the paper identifies three kinds of civil non-state actors in war-torn countries: international non-governmental organizations (NGOs), community-based NGOs, and ad hoc community organizations. In addition, it argues that civil non-state actors play a critical problem-solving role in peacekeeping and peacebuilding and complement the role of state actors. The paper examines the role of civil non-state actors through their dialectical affinity with state actors in the peacekeeping and peacebuilding processes. It further expands the notion of non-state actors …

Parentage Law (R)Evolution: The Key Questions, Jeffrey A. Parness Jan 2013

Parentage Law (R)Evolution: The Key Questions, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

American state parentage laws have evolved significantly in the past half century in response to changes in both reproductive technologies and human conduct. Yet further evolution, if not a revolution, seems inevitable. In particular, American state laws increasingly recognize parenthood by consent for a nonbiological and nonadoptive parent-like figure in an intimate or familial relationship with a child’s biological or adoptive parent. Lawmakers, especially state legislators, will need to consider who may be granted standing as parents to seek court-ordered childcare, including former stepparents, former boyfriends and girlfriends, and present and former grandparents. As well, they must ponder whether standing …
