Little is known about the role of protein dynamics in directing protein unfolding along a specific pathway and about the role played by chemical denaturants in modulating the dynamics and the initiation of unfolding. In this study, deuterium-hydrogen exchange (HX) detected by electrospray ionization mass spectrometry (ESI-MS) was used to study the unfolding of the SH3 domain of the PI3 kinase. ...

Carlsson, Linda, Daniel Lindén, Masoumeh Jalouli, and Jan Oscarsson. Effects of fatty acids and growth hormone on liver fatty acid binding protein and PPARa in rat liver. Am J Physiol Endocrinol Metab 281: E772–E781, 2001.—The aim of this study was to investigate the interaction between long-chain fatty acids (LCFA) and growth hormone (GH) in the regulation of liver fatty acid binding protein (...

Hox transcription factors control a number of developmental processes with the help of the PBC class proteins. In vitro analyses have established that the formation of Hox/PBC complexes relies on a short conserved Hox protein motif called the hexapeptide (HX). This paradigm is at the basis of the vast majority of experimental approaches dedicated to the study of Hox protein function. Here we qu...

The counter-regulatory effects of beta-adrenergic stimulation and cyclic AMP on the insulin-like action of growth hormone (GH) on the subcellular distribution of insulin-like growth factor II (IGF-II) receptors were studied in fat cells from hypophysectomized (Hx) and sham-operated rats. For comparison, the effect of insulin on this process was also studied. Basal IGF-II binding was increased b...

Present work reports the biological activities of P. hysterophorus leaf, stem, flower, and root. Dried samples were sequentially extracted with many solvents. Hexane (HX), benzene (BZ), and chloroform (CH) extracts of leaf showed considerable antibacterial activity against Streptococcus mutans (MTCC 497), Proteus vulgaris (MTCC 7299), and Salmonella typhi (MTCC 3917). Flower extracts exhibited ...

The data presented in this article are related to the research article entitled Hemopexin counteracts systolic dysfunction induced by heme-driven oxidative stress (G. Ingoglia, C. M. Sag, N. Rex, L. De Franceschi, F. Vinchi, J. Cimino, S. Petrillo, S. Wagner, K. Kreitmeier, L. Silengo, F. Altruda, L. S. Maier, E. Hirsch, A. Ghigo and E. Tolosano, 2017) [1]. Data show that heme induces reactive ...

The efficacy of hexanoic acid (Hx) as an inducer of resistance in tomato plants against Pseudomonas syringae pv. tomato DC3000 was previously demonstrated, and the plant response was characterized. Because little is known about the reaction of the pathogen to this effect, the goal of the present work was to determine whether the changes in the plant defence system affect the pathogen behaviour....

Previously, we reported a pronounced reduction in transmission through surviving axons contralateral to chronic hemisection (HX) of adult rat spinal cord. To examine the cellular and molecular mechanisms responsible for this diminished transmission, we recorded intracellularly from lumbar lateral white matter axons in deeply anesthetized adult rats in vivo and measured the propagation of action...

The effects of ovine prolactin (oPRL) and striped bass prolactin (sbPRL; Morone saxatilis) on plasma osmolality, electrolyte balance, and gill Na(+),K(+)-ATPase activity were investigated in hypophysectomized (Hx), freshwater (FW)-acclimated, hybrid striped bass (M. saxatilisxMorone chrysops). They were kept in dilute (isoosmotic) seawater for about 10 days after surgery. Seven days after trans...
