UCHC Articles - Research

Identification of a reliable marker of skeletal precursor cells within calcified and soft tissues remains a major challenge for the field. To address this, we used a transgenic model in which osteoblasts can be eliminated by pharmacological treatment. Following osteoblast ablation a dramatic increase in a population of α-smooth muscle actin (α-SMA) positive cells was observed. During early recovery phase from ablation we have detected cells with the simultaneous expression of SMAA and a preosteoblastic 3.6GFP marker, indicating the potential for transition of α-SMA+ cells towards osteoprogenitor lineage. Utilizing α-SMAGFP transgene, α-SMAGFP+ positive cells were detected in the …

Teriparatide (1-34 Human Pth) Regulation Of Osterix During Fracture Repair, Do Y. Soung, Graziello Geneau, Hicham Drissi

UCHC Articles - Research

Based on remarkable success of PTH as an anabolic drug for osteoporosis, case reports of off-label use of teriparatide (1-34 PTH) in patients with complicated fractures and non-unions are emerging. We investigated the mechanisms underlying PTH accelerated fracture repair. Bone marrow cells from 7 days 40cg/kg of teriparatide treated or saline control mice were cultured and Osx and osteoblast phenotypic gene expression assessed by real time RT-PCR in these cells. Fractured animals injected daily with either saline or 40cg/kg of teriparatide for up to 21 days were X-rayed and histological assessment performed, as well as immunohistochemical analyses of the Osx …


Amino(Oligo)Thiophene-Based Environmentally Sensitive Biomembrane Chromophores, Ping Yan, Aifang Xie, Meide Wei, Leslie M. Loew Sep 2008

Amino(Oligo)Thiophene-Based Environmentally Sensitive Biomembrane Chromophores, Ping Yan, Aifang Xie, Meide Wei, Leslie M. Loew

UCHC Articles - Research

There is a growing need for cellular imaging with fluorescent probes that emit at longer wavelengths to minimize the effects of absorption, autofluorescence and scattering from biological tissue. In this paper a series of new environmentally-sensitive hemicyanine dyes featuring amino(oligo)thiophene donors have been synthesized via aldol condensation between a 4-methylpyridinium salt and various amino(oligo)thiophene carboxaldehydes, which were, in turn, obtained from amination of bromo (oligo)thiophene carboxaldehyde. Side chains on these fluorophores impart a strong affinity for biological membranes. Compared with benzene analogues, these thiophene fluorophores show significant red shift in the absorption and emission spectra, offering compact red and near-infrared …


Actin Bundling: Initiation Mechanisms And Kinetics, Pavel Kraikivski, Boris M. Slepchenko, Igor Igor L. Novak Sep 2008

Actin Bundling: Initiation Mechanisms And Kinetics, Pavel Kraikivski, Boris M. Slepchenko, Igor Igor L. Novak

UCHC Articles - Research

Bundling of rapidly polymerizing actin filaments underlies dynamics of filopodial protrusions that play an important role in cell migration and cell-cell interaction. Recently, formation of actin bundles has been reconstituted in vitro and two scenarios of bundle initiation, involving binding of two filament tips and, alternatively, linking of the tip of one filament to the side of the other, -have been discussed. A first theoretical analysis is presented indicating that the two mechanisms can be distinguished experimentally. While both of them result counter-intuitively in comparable numbers of bundles, these numbers scale differently with the average bundle length. We propose an …


A Crucial Role In Cell Spreading For The Interaction Of Abl Pxxp Motifs With Crk And Nck Adaptors, Susumu Antoku, Gonzalo M. Rivera, Bruce J. Mayer Sep 2008

A Crucial Role In Cell Spreading For The Interaction Of Abl Pxxp Motifs With Crk And Nck Adaptors, Susumu Antoku, Gonzalo M. Rivera, Bruce J. Mayer

UCHC Articles - Research

The dynamic reorganization of actin structures helps to mediate the interaction of cells with their environment. The Abl non-receptor tyrosine kinase can modulate actin rearrangement during cell attachment. Here we report that the Abl PxxP motifs, which bind Src homology 3 (SH3) domains, are indispensable for the coordinated regulation of filopodium and focal adhesion formation and cell-spreading dynamics during attachment. Candidate Abl PxxP-motif-binding partners were identified by screening a comprehensive SH3-domain phage-display library. A combination of protein overexpression, silencing, pharmacological manipulation and mutational analysis demonstrated that the PxxP motifs of Abl exert their effects on actin organization by two distinct …

Population Structure Of Coyote (Canis Latrans) In The Urban Landscape Of The Cleveland, Ohio Area, Rebecca M. Rashleigh, Robert A. Krebs, Harry Van Keulen

Biological, Geological, and Environmental Faculty Publications

To obtain information on the population structure of coyote (Canis latrans) in an urban setting, a non-invasive genetic sampling technique was applied that consisted of DNA isolation from scat collected around the Cleveland metropolitan area. Muscle tissue was provided from two other coyotes. Amplifying the mitochondrial D-loop or control region produced 33 haplotypes from just 57 coyote sequences and two additional dog sequences from putative coyote-dog hybrids. The mitochondrial DNA genetic diversity in the Cleveland area was high, π 0.02, and composed of six distinct haplotype lineages. In addition, Fst values ranged from 0.07 between collections east and west of …

Peterson, Susan Pourciau, Min Du, Rachel Lacasse, Melissa Pathmajeyan, David J. Poulsen, Mavis Agbandje-Mckenna, Kathy Wehrly, Bruce Chesebro

Biomedical and Pharmaceutical Sciences Faculty Publications

Changes in the envelope proteins of retroviruses can alter the ability of these viruses to infect the central nervous system (CNS) and induce neurological disease. In the present study, nine envelope residues were found to influence neurovirulence of the Friend murine polytropic retrovirus Fr98. When projected on a three-dimensional model, these residues were clustered in two spatially separated groups, one in variable region B of the receptor binding site and the other on the opposite side of the envelope. Further studies indicated a role for these residues in virus replication in the CNS, although the residues did not affect viral …
