We have cloned Pfnek-1, a gene encoding a novel protein kinase from the human malaria parasite Plasmodium falciparum. This enzyme displays maximal homology to the never-in-mitosis/Aspergillus (NIMA)/NIMA-like kinase (Nek) family of protein kinases, whose m ...
Cytokines can be produced within the nervous system by various cell types, including astrocytes, which secrete them in response to pathological processes such as viral infections. Astrocytes are known to play an important role in the homeostasis of the ner ...
Transcription factor AP-1 is constituted by the various products of the fos and jun proto-oncogene family members, which associate as dimers to bind with variable efficiency to 12-O-tetradecanoyl phorbol 13-acetate (TPA)-responsive promoter elements (TREs) ...
The Nef protein is important in HIV replication and in AIDS pathogenesis. The finding that Nef activates a member of the PAK family of protein kinases provides new insights into the mechanisms of action of this critical virulence factor. ...
The surge of interest in protein kinases as targets for chemotherapeutic intervention in a number of diseases such as cancer and neurodegenerative disorders has stimulated research aimed at determining whether enzymes of this class might also be considered ...
OBJECTIVE: Oxidized low-density lipoproteins (ox-LDL) or their components suppress macrophage inflammatory response by down-regulating cytokine synthesis, nitric oxide synthase and inducible cyclooxygenase (Cox-2). This event is crucial for the pathophysio ...

The three peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors of the nuclear hormone receptor superfamily. They share a high degree of structural homology with all members of the superfamily, particularly in the D ...

Granulocyte-colony-stimulating factor (G-CSF) stimulates the proliferation and differentiation of cells of the neutrophil lineage by interaction with a specific receptor. Early signal transduction events following G-CSF receptor activation were studied. We ...
The receptor-like protein kinase PknB from Mycobacterium tuberculosis is encoded by the distal gene in a highly conserved operon, present in all actinobacteria, that may control cell shape and cell division. Genes coding for a PknB-like protein kinase are ...
Recently, it was shown that lipoprotein lipase (LPL) was produced in neonatal but not in adult rat liver. In an attempt to further define the mechanism involved in liver LPL expression, we identified a neonatal mouse hepatoma cell line, BWTG3, capable of p ...
