Protein tyrosine phosphorylation and protein tyrosine nitration in redox signaling
(Mary Ann Liebert Inc, 2008-05-01)
Reversible phosphorylation of protein tyrosine residues by polypeptide growth factor-receptor protein tyrosine kinases is implicated in the control of fundamental cellular processes including the cell cycle, cell adhesion, ...
The multitude of targets for the immune system and drug therapy in the fungal cell wall
(Elsevier B.V., 2005-04-01)
Recent studies on fungi revealed that several cytosolic and membrane components migrate to the cell wall together with secreted proteins and biosynthetic polysaccharides to build a dynamic immunoreactive structure. New ...

Cyclopalladated compounds as chemotherapeutic agents: Antitumor activity against a murine melanoma cell line
(Wiley-Blackwell, 2003-11-10)
Palladacycle compounds obtained from N, N-dimethyl- I phenethylamine (dmpa), phenyl-2-pyridinyl-acetylene and 1-phenyl-3-N, N-dimethylamine-propine, respectively, were complexed to 1, 2 ethanebis (diphenylphosphine) (dppe) ...
Detection of the basement membrane-degrading proteolytic activity of Paracoccidioides brasiliensis after SDS-PAGE using agarose overlays containing Abz-MKALTLQ-EDDnp
(Associação Brasileira de Divulgação Científica, 1999-05-01)
We have characterized, in the Paracoccidioides brasiliensis yeast phase, an exocellular SH-dependent serine proteinase activity against Abz-MKRLTL-EDDnp and analogous fluorescent-quenched peptides, and showed that it is ...
P16INK4a expression as a potential prognostic marker in cervical pre-neoplastic and neoplastic lesions
(2006)
An immunohistochemical analysis with monoclonal antibody p16INK4a was performed in formalin-fixed, paraffin-embedded samples of 60 cases. The aim was to investigate in biopsies the expression of p16INK4a of normal uterine ...
