ABSTRACT We have identified Math5, a mouse basic helix-loop-helix (bHLH) gene that is closely related to Drosophila atonal and Xenopus Xath5 largely restricted the developing eye. Math5 retinal expression precedes differentiation of first neurons persists within progenitor cells until after birth. To position in hierarchy development, we compared Hes1 wild-type Pax6-deficient (Sey) embryos. downregulated Sey/+ eyes abolished Sey/Sey eye rudiments, whereas bHLH upregulated similar...
Abstract Summary: The eyeless inbred mouse strain ZRDCT has long served as a spontaneous model for human anophthalmia and the evolutionary reduction of eyes that occurred in some naturally blind mammals. mice have orbits but lack optic tracts hypothalamic abnormalities. Segregation data suggest small number interacting genes are responsible, including at least one major recessive locus, ey1 . Although predicted since 1940s, these loci were never identified. We mapped to chromosome 18 using...
Kanekar, Shami, Olena V. Bogdanova, Paul R. Olson, Young-Hoon Sung, Kristen E. D'Anci, and Perry F. Renshaw. Hypobaric hypoxia induces depression-like behavior in female Sprague-Dawley rats, but not males. High Alt Med Biol 16:52–60, 2015—Rates of depression suicide are higher people living at altitude, those with chronic hypoxic disorders like asthma, obstructive pulmonary disorder (COPD), smoking. Living altitude exposes to hypobaric hypoxia, which can lower rat brain serotonin levels,...
Sheth, Chandni, Hendrik Ombach, Paul Olson, Perry F. Renshaw, and Shami Kanekar. Increased anxiety anhedonia in female rats following exposure to altitude. High Alt Med Biol. 19:81-90, 2018.-Anxiety disorders are chronic, highly prevalent conditions, often comorbid with depression. Both depression form major risk factors for suicide. Living at altitude is associated higher rates of suicide, leading us address whether may also be amplified Using a novel translational animal model, we...
Abstract One premise regarding the mechanism of injury‐evoked neuroregeneration is that injured cells induce release neurotrophic factors to trigger neurogenesis. Extracellular purine nucleotides exert multiple actions in central nervous system mediated via activation purinergic receptors. However, whether purinergics have a role olfactory neuroepithelium has not been investigated. Thus, we monitored ATP‐induced neuropeptide Y (NPY), increases neuroproliferation epithelium. To visualize NPY...
Background: Rates of major depressive disorder (MDD) increase with living at altitude. In our model, rats housed moderate altitude (in hypobaric hypoxia) exhibit increased depression-like behavior, altered brain serotonin and a lack antidepressant response to most selective reuptake inhibitors (SSRIs). A forebrain deficit in the bioenergetic marker creatine is noted people or MDD. Methods: Rats 4500 ft were given dietary monohydrate (CRMH, 4% w/w, 5 weeks) vs. un-supplemented diet, impact on...
Summary Insect and vertebrate eyes differ in their formation, cellular composition, neural connectivity, visual function. Despite this diversity, Drosophila atonal its Ortholog the eye, Ath5 , each regulate determination of first retinal neuron class—R8 photo‐receptors ganglion cells (RGCs)—in respective organisms. We have performed a cross‐species functional comparison these genes. In ato 1 mutant ectopic Xenopus ( Xath5 ) rescues photoreceptor cell development comparably with . contrast,...
Prescription opioid misuse and fatal overdoses have increased significantly over the last two decades. Living at altitude has been linked to greater reward benefits of other drugs abuse, living may also exacerbate respiratory depression use. Therefore, we examined relationships between altitude, prescription overdoses.
The signals for injury-evoked neuroregeneration are unknown; however previous studies implied that injured cells secrete neurotrophic factors which trigger neurogenesis. Extracellular purine nucleotides exert multiple actions in the CNS mediated via activation of purinergic (P2) receptors. Our work demonstrated ATP acts as a neuromodulator and stress signal olfactory epithelium (OE). To determine whether P2 receptor evokes factor secretion OE, we monitored release NPY, neuroproliferative...
Abstract In the adult spinal cord, immunocytochemical staining for NT75 is concentrated in nerve terminals superficial laminae of dorsal horn. Deeper horn contain moderate labeling, but ventral only sparsely stained. The origin containing was investigated with lesion techniques, colchicine treatment, and retrograde tracing combination staining. Primary afferent neurons express immunoreactivity account most dense part labeling deeper laminae. It found that corticospinal virtually all...
