The polyamine spermine induces the unfolded protein response via the MAPK cascade in Arabidopsis
In Arabidopsis three basic region leucine zipper (bZIP) transcription factor genes, bZIP17, bZIP28 and bZIP60, play crucial roles in the unfolded protein response (UPR). Previously we found that bZIP60 is one of the spermine-induces genes.

Mitogen-activated Protein Kinase Phosphorylates and Regulates the HIV-1 Vif Protein [PDF]
The human immunodeficiency virus type 1 (HIV-1) Vif protein plays a critical role in virus replication and infectivity. Here we show that Vif is phosphorylated and regulated by p44/42 mitogen-activated protein kinase (MAPK). Vif phosphorylation by MAPK was demonstrated in vitro as well as in vivo and was shown to occur on serine and threonine residues.

Reciprocal control of viral infection and phosphoinositide dynamics
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The role of p38 MAPK and its substrates in neuronal plasticity and neurodegenerative disease [PDF]
A significant amount of evidence suggests that the p38-mitogen-activated protein kinase (MAPK) signalling cascade plays a crucial role in synaptic plasticity and in neurodegenerative diseases.

ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Although spleen tyrosine kinase (Syk) has crucial roles in various cells, its function on vascular smooth muscle contraction has not been determined. In the present study, we performed experiments to determine if Syk contributes to the endothelin-1 (ET-1)

Chronic GLP-1 receptor activation by exendin-4 induces expansion of pancreatic duct glands in rats and accelerates formation of dysplastic lesions and chronic pancreatitis in the Kras(G12D) mouse model. [PDF]
Pancreatic duct glands (PDGs) have been hypothesized to give rise to pancreatic intraepithelial neoplasia (PanIN). Treatment with the glucagon-like peptide (GLP)-1 analog, exendin-4, for 12 weeks induced the expansion of PDGs with mucinous metaplasia and

Mitogen regulation of c-Raf-1 protein kinase activity toward mitogen-activated protein kinase-kinase
The c-raf-1 protooncogene encodes a Ser/Thr protein kinase. A mitogen-activated protein kinase-kinase (MAPKK) purified from bovine brain is phosphorylated and activated 4-9-fold in vitro by c-Raf-1 from mitogen-treated cells. c-Raf-1 protein kinase activity, measured by the phosphorylation of brain MAPKK substrate, is detectably activated within 1 min ...
