Thyrotropin receptor (TSH-R) has been thought to be thyroid-specific, but, by Northern blot analysis, we found that rat adipose tissue expressed TSH-R mRNAs in amounts approaching those in the thyroid. To investigate the function of TSH-R from adipose tissue, we screened a rat fat cell lambda gt11 cDNA library for ... More

'Paneth cells in small intestinal crypts secrete microbicidal alpha-defensins in response to bacteria and bacterial antigens (Ayabe, T., Satchell, D. P., Wilson, C. L., Parks, W. C., Selsted, M. E., and Ouellette, A. J. (2000) Nat. Immunol. 1, 113- 38). We now report that the Ca(2+)-activated K(+) channel mIKCa1 modulates ... More
Variant forms of alpha-fetoprotein transcripts expressed in human hematopoietic progenitors. Implications for their developmental potential towards endoderm.
Authors: Kubota Hiroshi; Storms Robert W; Reid Lola M;
Journal:J Biol Chem
PubMed ID:12006569
'Hematopoietic stem cells have been identified as multipotent cells that give rise to all adult hematopoietic lineages. Although the hematopoietic lineage is derived from the mesodermal germ layer in the embryo, recent data suggest that bone marrow cells with an antigenic profile consistent with that of hematopoietic stem cells can ...

Mutation of the matrix metalloproteinase At2-MMP inhibits growth and causes late flowering and early senescence in Arabidopsis.
Authors: Golldack Dortje; Popova Olga V; Dietz Karl-Josef;
Journal:J Biol Chem
PubMed ID:11726650
'This study characterizes the expression and functional significance of the member of the matrix metalloproteinase (MMP) family At2-MMP from Arabidopsis. By transcript analysis, expression of At2-MMP was found in leaves and roots of juvenile Arabidopsis and leaves, roots, and inflorescences of mature flowering plants showing strong increase of transcript abundance ...

Phosphorylation of the Carboxyl Terminus of Inner Centromere Protein (INCENP) by the Aurora B Kinase Stimulates Aurora B Kinase Activity.
Authors: Bishop John D; Schumacher Jill M;
Journal:J Biol Chem
PubMed ID:12048181
'How the events of mitosis are coordinated is not well understood. Intriguing mitotic regulators include the chromosomal passenger proteins. Loss of either of the passengers inner centromere protein (INCENP) or the Aurora B kinase results in chromosome segregation defects and failures in cytokinesis. Furthermore, INCENP and Aurora B have identical ... More
