Recurrent Co-Option and Recombination of Cytokine and Three Finger Proteins in Multiple Reproductive Tissues Throughout Salamander Evolution

Autor: Damien B. Wilburn, Christy L. Kunkel, Richard C. Feldhoff, Pamela W. Feldhoff, Brian C. Searle

Publikováno v: Frontiers in Cell and Developmental Biology, Vol 10 (2022)

Reproductive proteins evolve at unparalleled rates, resulting in tremendous diversity of both molecular composition and biochemical function between gametes of different taxonomic clades. To date, the proteomic composition of amphibian gametes is lar

Structural insights into the evolution of a sexy protein: novel topology and restricted backbone flexibility in a hypervariable pheromone from the red-legged salamander, Plethodon shermani.

Autor: Damien B Wilburn, Kathleen E Bowen, Kari A Doty, Sengodagounder Arumugam, Andrew N Lane, Pamela W Feldhoff, Richard C Feldhoff

Publikováno v: PLoS ONE, Vol 9, Iss 5, p e96975 (2014)

In response to pervasive sexual selection, protein sex pheromones often display rapid mutation and accelerated evolution of corresponding gene sequences. For proteins, the general dogma is that structure is maintained even as sequence or function may

Gonadotropin-Releasing Hormone Modulates Vomeronasal Neuron Response to Male Salamander Pheromone

Autor: Celeste R. Wirsig-Wiechmann, Justin Colvard, Christopher E. Aston, Radhika Dighe, Lynne D. Houck, Pamela W. Feldhoff, Richard C. Feldhoff

Publikováno v: Journal of Experimental Neuroscience, Vol 6 (2012)

Electrophysiological studies have shown that gonadotropin-releasing hormone (GnRH) modifies chemosensory neurons responses to odors. We have previously demonstrated that male Plethodon shermani pheromone stimulates vomeronasal neurons in the female c

Effect of surface-attached heparin on the response of potassium-selective electrodes

Autor: K A, Brooks, J R, Allen, P W, Feldhoff, L G, Bachas

Publikováno v: Analytical chemistry. 68(8)

Heparin (or hydrolyzed heparin) was covalently attached on the surface of derivatized cellulose triacetate membranes, which were subsequently impregnated with the potassium-selective ionophore valinomycin. The resulting ion-selective electrodes prese

Alterations in the topoisomerase II alpha gene, messenger RNA, and subcellular protein distribution as well as reduced expression of the DNA topoisomerase II beta enzyme in a mitoxantrone-resistant HL-60 human leukemia cell line

Autor: W G, Harker, D L, Slade, R L, Parr, P W, Feldhoff, D M, Sullivan, M H, Holguin

Publikováno v: Cancer research. 55(8)

A human HL-60 leukemia cell line selected for resistance to mitoxantrone, HL-60/MX2, displays cross-resistance only to agents whose cytotoxicities result from interaction with the nuclear enzyme DNA topoisomerase II (topo II). The topo II catalytic a

Altered subcellular distribution of topoisomerase II alpha in a drug-resistant human small cell lung cancer cell line

Autor: P W, Feldhoff, S E, Mirski, S P, Cole, D M, Sullivan

Publikováno v: Cancer research. 54(3)

A drug-resistant human small cell lung cancer cell line, H209/V6, selected in the presence of increasing concentrations of 9-(4,6-O-ethylidene-beta-D-glucopyranosyl)-4'-demethylepipodophylloto xin (VP-16) from parental H209 cells, is 22-, 9-, and 4-f

Development of Affinity Membranes

Autor: P. W. Feldhoff

Publikováno v: Immobilised Macromolecules: Application Potentials ISBN: 9781447134817

In the development of affinity membrane technology, several areas of expertise come together and each has a basis of knowledge that contributes to the goal of affinity membrane separation (Fig. 5.1).

14C-labeled proteins as markers for gradient analysis of steroid-hormone receptors

Autor: R C Feldhoff, James L. Wittliff, D J Ledden, P W Feldhoff, P H Heidemann

Publikováno v: Clinical Chemistry. 27:1357-1361

Two useful [14C]marker proteins--[14C]human serum albumin (4.6S) and [14C]glucose oxidase (7.9S)--can be simply prepared. Both may be used as molecular-mass standards in polyacrylamide gel electrophoresis as sucrose density-gradient centrifugation. T
