After therapeutic hormone deprivation, prostate cancer (CaP) cells often develop androgen-independent growth through not-well-defined mechanisms. The presence of neuroendocrine (NE) cells is often greater in prostate carcinoma than in normal prostate, and the frequency of NE cells correlates with tumor malignancy, loss of androgen sensitivity, increase of autocrine-paracrine activity, and poor ...

Almost all large-scale projects in mass spectrometry-based proteomics use trypsin to convert protein mixtures into more readily analyzable peptide populations. When searching peptide fragmentation spectra against sequence databases, potentially matching peptide sequences can be required to conform to tryptic specificity, namely, cleavage exclusively C-terminal to arginine or lysine. In many pub...
Rheumatoid arthritis (RA) is an autoimmune disease of complex etiology. A characteristic feature of a subset of RA is the presence of anti-citrullinated protein antibodies (ACPA), which correlate with a progressive disease course. In this study, we employed streptavidin capture enzyme-linked immunosorbent assay to analyze ACPA reactivity. Using the pro-filaggrin peptide HQCHQEST-Cit-GRSRGRCGRSG...
Sex peptide (SP) and Ductus ejaculatorius peptide (Dup) 99B are synthesized in the retrogonadal complex of adult male Drosophila melanogaster, and are transferred in the male seminal fluid to the female genital tract during mating. They have been sequenced and shown to exhibit a high degree of homology in the C-terminal region. Both affect subsequent mating and oviposition by female D. melanoga...
Ligand-activated and tyrosine-phosphorylated ErbB3 receptor binds to the SH2 domain of the p85 subunit of phosphatidylinositol 3-kinase and initiates intracellular signaling. Here, we studied the interactions between the N- (N-SH2) and C- (C-SH2) terminal SH2 domains of the p85 subunit of the phosphatidylinositol 3-kinase and eight ErbB3 receptor-derived phosphotyrosyl peptides (P-peptides) by ...
Tachykinin-like peptides, such as substance P, neurokinin A, and B, are among the earliest discovered best-studied neuropeptide families, research on them has contributed greatly to our understanding of endocrine control many physiological processes. However, there still orphan tachykinin receptor homologs for which cognate ligands have not yet been identified, especially in small invertebrates...
Pep M5, the pepsin-derived N-terminal half of the group A streptococcal type 5 M protein exhibits immunologic crossreaction with type 6 M protein, localizing some of the M6-crossreactive epitope(s) within this segment of the M5 protein. Based on the amino acid sequence of the Pep M5 protein, two structurally distinct domains have been recognized within its coiled-coil structure. We have now fou...
Peptide synthesis is widely used for the production of small proteins and peptides, but producing uniformly isotopically labelled peptides for NMR and other biophysical studies could be limited for economic reasons. Here, we propose a use of a modified pGEV-1 plasmid to express neurotensin (NT(1-13)), pGlu(1)-Leu(2)-Tyr(3)-Glu(4)-Asn(5)-Lys(6)-Pro(7)-Arg(8)-Arg(9)-Pro(10)-Tyr(11)-Ile(12)-Leu(13...
