Novel expression patterns of phosphatidylinositol 3-hydroxy kinase in nodulated Medicago spp. plants

Novel expression patterns of phosphatidylinositol 3-hydroxy kinase in nodulated Medicago spp. plants.

A cDNA clone encoding a phosphatidylinositol 3-kinase (PtdIns 3-kinase) has been characterized from Medicago truncatula, Mtpi3k, that is highly homologous to their counterparts from soybean (over 84%). The results suggest the presence of at least two genes coding PtdIns 3-kinases in M. truncatula. Mtpi3k transcript levels increased in nodules, compared with non-infected roots. Strikingly, Mtpi3...

Phosphatidylinositol 3-kinase: a novel effector.

A number of years ago, when the raison d’#{234}tre for tyrosine kinase activity was completely unclear, one of the tantalizing leads was the apparent coincidence of inositol lipid kinase activity with certain tyrosine kinases (see, for example Refs. 1 and 2); the exciting prospect implied was a link to a well defined signal transduction pathway (for a review of inositol lipid kinases, see Ref. ...

Involvement of Phosphatidylinositol 3-Kinase

Phosphatidylinositol 3 kinase pathway and 4-hydroxy-2-nonenal-induced oxidative injury in the RPE.

PURPOSE 4-Hydroxy-2-nonenal (4-HNE) is a major lipid peroxidation product in the retina and the retinal pigment epithelium. The purpose of the present study was to investigate how NF-E2-related factor-2 (Nrf2) and phosphatidylinositol 3 (PI3K) pathways affect the responses of cultured human retinal pigment epithelial (RPE) cells to 4-HNE. METHODS Cultured ARPE-19 cells were treated with diffe...
