Nguyen N, Fernando S, Biette K, Hammer J, Capocelli K, Kitzenberg D, et al.
Mucosal Immunol . 2017 Aug; 11(2):415-426. PMID: 28832026
Barrier dysfunction has been implicated in the pathophysiology of eosinophilic esophagitis (EoE). Transforming growth factor-β1 (TGF-β1), a potent pleiotropic molecule, is increased in EoE; however, no study has evaluated its...

Weyrauch T, Vorontsov M, Bifano T, Hammer J, Cohen M, Cauwenberghs G
Appl Opt . 2008 Mar; 40(24):4243-53. PMID: 18360462
The performance of adaptive systems that consist of microscale on-chip elements [microelectromechanical mirror (mu-mirror) arrays and a VLSI stochastic gradient descent microelectronic control system] is analyzed. The mu-mirror arrays with...

Madhavarao C, Hammer J, Quarles R, Namboodiri M
Anal Biochem . 2002 Nov; 308(2):314-9. PMID: 12419345
Recent studies have shown that aspartoacylase (ASPA), the defective enzyme in Canavan disease, is detectable in the brain only in the oligodendrocytes. Studying the regulation of ASPA is central to...

Franzen R, Tanner S, Dashiell S, Rottkamp C, Hammer J, Quarles R
J Cell Biol . 2001 Dec; 155(6):893-8. PMID: 11733546
Myelin-associated glycoprotein (MAG) is expressed in periaxonal membranes of myelinating glia where it is believed to function in glia-axon interactions by binding to a component of the axolemma. Experiments involving...

Gillespie P, Albanesi J, Bahler M, Bement W, Berg J, Burgess D, et al.
J Cell Biol . 2001 Nov; 155(5):703-4. PMID: 11724811
We suggest that the vertebrate myosin-I field adopt a common nomenclature system based on the names adopted by the Human Genome Organization (HUGO). At present, the myosin-I nomenclature is very...

Yim S, Hammer J, Quarles R
J Neurochem . 2001 Mar; 76(6):1925-34. PMID: 11259511
Treatment of cultured rat oligodendroglial progenitors with either platelet-derived growth factor (PDGF) or fibroblast growth factor-2 (FGF-2) activated extracellular signal regulated kinase 2 (ERK2). Activation was transient in response to...

Yim S, Farrer R, Hammer J, Yavin E, Quarles R
J Neurosci Res . 1994 Jun; 38(3):268-81. PMID: 7523687
Cultures consisting primarily of O-2A progenitor cells and immature oligodendrocytes with a few microglia and astrocytes were obtained by shaking primary cultures from neonatal rat brain after 12-14 days in...

Hammer J, OShannessy D, De Leon M, Gould R, Zand D, Daune G, et al.
J Neurosci Res . 1993 Aug; 35(5):546-58. PMID: 7690857
Mammalian peripheral nervous system (PNS) myelin contains several glycoproteins with molecular weights of 19 to 28 kDa, including the major 28 kDa P0 glycoprotein and a recently cloned protein called...

Yim S, Yavin E, Hammer J, Quarles R
J Neurochem . 1991 Dec; 57(6):2144-7. PMID: 1940921
Isolated adult bovine oligodendrocytes maintained in vitro for 10 days were treated for 1 day with 50 micrograms/ml of GM3 ganglioside (NeuNac alpha 2-3Gal beta 1-4Glc beta 1-1'ceramide) in serum-free...

Hammer J
Trends Cell Biol . 1991 Aug; 1(2-3):50-6. PMID: 14731566
The traditional view of myosin, drawn from studies of myosins from striated muscles, is that of an elongated two-headed molecule that assembles into filaments. However, biochemical, molecular genetic and genetic...
