Eliciting The Low-Activity Aldehyde Dehydrogenase Asian Phenotype By An Antisense Mechanism Results In An Aversion To Ethanol., E Garver, Tu Gc, Q N Cao, M Aini, F Zhou, Y Israel

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

A mutation in the gene encoding for the liver mitochondrial aldehyde dehydrogenase (ALDH2-2), present in some Asian populations, lowers or abolishes the activity of this enzyme and results in elevations in blood acetaldehyde upon ethanol consumption, a phenotype that greatly protects against alcohol abuse and alcoholism. We have determined whether the administration of antisense phosphorothioate oligonucleotides (ASOs) can mimic the low-activity ALDH2-2 Asian phenotype. Rat hepatoma cells incubated for 24 h with an antisense oligonucleotide (ASO-9) showed reductions in ALDH2 mRNA levels of 85% and ALDH2 (half-life of 22 h) activity of 55% equivalent to a >90% inhibition in ALDH2 …

Acidification-Induced Sensitization To Thermoradiotherapy In Breast Cancer, Dennis B. Leeper, L T. Komarnicky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Hyperthermia is an extensively studied cytotoxic agent, with strong radio- and chemosensitizing potential. Recent positive clinical trials combining superficial or deep heating techniques with radiation therapy strongly support a role for hyperthermia as an adjuvant to radiation. Many in vitro and in vivo studies have shown that acute extracellular acidification will compromise fundamental protective cellular responses and enhance tumor response to hyperthermia and chemotherapy.

Breast cancers, like most other tumors, exhibit elevated levels of lactate production that provides a basis for selective acidification. A phase I/II clinical trial is underway to test the hypothesis that hyperglycemia-induced acute acidification will sensitize …

Interaction Between Fgf And Bmp Signaling Pathways Regulates Development Of Metanephric Mesenchyme., Andrew T. Dudley, R. E. Godin, E. J. Robertson

Journal Articles: Genetics, Cell Biology & Anatomy

Nephrogenesis in the mouse kidney begins at embryonic day 11 and ends approximately 10 days postpartum. During this period, new nephrons are continually being generated from a stem-cell population-the nephrogenic mesenchyme-in response to signals emanating from the tips of the branching ureter. Relatively little is known about the mechanism by which the nephrogenic mesenchyme cell population is maintained at the tips of the ureter in the presence of signals promoting tubulogenesis. Previous studies have shown that a loss of Bmp7 function leads to kidney defects that are a likely result of progressive loss of nephrogenic mesenchyme by apoptosis. The studies …

Transgenic Mice Which Overexpress Neurotrophin-3 (Nt-3) And Method Of Use, Kathryn M. Albers, Brian M. Davis

Neuroscience Faculty Patents

Transgenic mice express increased levels of neurotrophin-3 (NT-3) in epithelium when their ancestors are microinjected with the NT-3 gene. The NT-3 growth factor expressing transgenic mice are useful in the study of neurodegenerative disorders of the brain such as Parkinson's syndrome and Alzheimer's disease, of the spinal cord motor neurons such as amyotrophic lateral sclerosis, and for testing drug candidates for the treatment of these diseases.

Transgenic Mice Which Overexpress Nerve Growth Factor, Kathryn M. Albers, Brian M. Davis

Neuroscience Faculty Patents

Transgenic mice that express increased levels of nerve growth factor (NGF) in the epidermis and other stratified, keratinized epithelium. The nerve growth factor expressing transgenic mice are useful in the study of neurodegenerative disorders of the brain such as Parkinson's syndrome and Alzheimer's disease and for testing for drug candidates for the treatment of these diseases.

A Requirement For Bone Morphogenetic Protein-7 During Development Of The Mammalian Kidney And Eye., Andrew T. Dudley, K. M. Lyons, E. J. Robertson

Journal Articles: Genetics, Cell Biology & Anatomy

BMP-7/OP-1, a member of the transforming growth factor-beta (TGF-beta) family of secreted growth factors, is expressed during mouse embryogenesis in a pattern suggesting potential roles in a variety of inductive tissue interactions. The present study demonstrates that mice lacking BMP-7 display severe defects confined to the developing kidney and eye. Surprisingly, the early inductive tissue interactions responsible for establishing both organs appear largely unaffected. However, the absence of BMP-7 disrupts the subsequent cellular interactions required for their continued growth and development. Consequently, homozygous mutant animals exhibit renal dysplasia and anophthalmia at birth. Overall, these findings identify BMP-7 as an essential …

Activation Of Long Descending Propriospinal Neurons In Cat Spinal Cord, Robert J. Adams, Robert D. Skinner, Ronald S. Remmel

Journal of the Arkansas Academy of Science

Isolated mammalian spinal cord has been shown capable of generating locomotor activity. Propriospinal systems assumed to coordinate fore- and hindlimb activity are poorly understood. This study characterizes the long descending propriospinal (LDP) neurons in terms of the location of the somas and their peripheral inputs by direct neuronal recording. Anatomical studies using axonal retrograde transport of horseradish peroxidase from the lumbar to the cervical spinal cord as a tracer first described these neurons. Two hundred and thirty-one LDP neurons were identified in electrophysiological experiments. Of these, 123 responded to natural stimulation, and about 50% of the others were activated only …

Connections Of The Mesencephalic Locomotor Region (Mlr) In The Cat, E. Garcia-Rill, Robert D. Skinner, S. A. Gilmore

Journal of the Arkansas Academy of Science

The cat entopeduncular nucleus (EN), which is the main output of the basal ganglia, is known to project to the mesencephalic tegmentum. We have been able to elicit antidromic responses in single EN neurons from the region of the mesencephalic locomotor region (MLR), then transect (precollicular-postmamillary) the brainstem and elicit rhythmic movements of the limbs by stimulation of the same site in the same animal. Injections of the fluorescent dye 2,4 diamidino phenylindole 2 HCL (DAPI) into this area induces retrograde labeling of cell bodies in EN and motor cortex. Injections of a tritiated amino acid (leucine) into the motor …

The primary objectives of this study were to determine: 1) the pathway of the superior alveolar nerves and their relation to the maxillary molar tooth buds in the fetal and neonatal specimens and in the child, and 2) whether nerve fibers entered any microscopically-observed tooth buds.

Anatomical Texts

A paper affixed to the rear free endpaper of the item states that is edition contains “fine reproductions of the Gemini plates.”

“Thomas Geminus was a a pseudonym for Thomas Lambrit, an engraver and printer…shown as active from about 1540; he died in May 1562.” http://www.arsanatomica.lib.ed.ac.uk/geminus.html accessed 11/20/2012. Geminus (Lambrit) printed Compendiosa totius anatomiae delineation aere exarata in 1545 copied from Vesalius’ 1543, De humani corporis fabrica . (Wellcome Library catalog, accessed 11/20/2012.)

This book is a 1617 reproduction of the engraved copperplates which Lambrit himself copied from the original woodblock prints of the Vesalius’ book.
