Ysis of pheromone-dependent gene transcription in WT and reg1 cells. Cells
Ysis of pheromone-dependent gene transcription in WT and reg1 cells. Cells expressing a FUS1-lacZ reporter were treated using the indicated concentrations of -factor for 90 min, after which -galactosidase activity was measured. Data are means SEM from three experiments, each and every performed in quadruplicate. Data are expressed as a percentage in the -galactosidase activity of WT cells at the maximum concentration of pheromone.

Crosstalk involving mating and glucose-sensing pathways(A to C) Evaluation of your effects of higher and low glucose around the abundance and phosphorylation of Fus3. (A) WT cells, (B) elm1sak1tos3 cells, and (C) reg1 cells had been cultured in medium containing two or 0.05 glucose for 5 min just before becoming left untreated or treated with three -factor (-F) for the indicated instances ahead of they have been harvested for analysis. Prime: Samples had been analyzed by Western blotting with antibody against phosphorylated p4442 MAPK (to detect p-Fus3 and p-Kss1), as well as with antibodies distinct for total Fus3, Gpa1, phosphorylated Snf1 (p-Snf1), and G6PDH, which was applied as a loading control. Middle: Densitometric evaluation of your abundance of p-Fus3. Bottom: Densitometric analysis from the abundance of total Fus3. For densitometric evaluation, by far the most intense band on each and every blot was set at 100 , plus the intensities in the other bands had been expressed as percentages of your maximum. Final results are suggests SEM from 3 independent experiments.

Information are expressed as percentages from the -galactosidase activity of pheromone-treated WT cells cultured in 2 glucose, which was set at one hundred . Information are implies SEM from three independent experiments, each performed in quadruplicate. P 0.05. (E) WT cells had been transformed with empty plasmid or with plasmid encoding STE11-4, a constitutively active mutant with the MAPKKK Ste11. Early og phase cells were resuspended in medium containing either 2 or 0.05 glucose. Cells transformed with empty plasmid were treated with 3 -factor for five min, whereas cells expressing STE11-4 have been collected 5 min right after resuspension in fresh medium. Samples were analyzed by Western blotting with antibodies against phosphorylated p4442 MAPK and total Fus3. Bar graphs represent densitometric analysis in the intensities of bands GLUT3 list corresponding to p-Fus3, normalized to these corresponding to total Fus3. For every set of cells, the abundance of p-Fus3 in 2 glucose was set at 100 . Data are indicates SEM from three independent experiments.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptSci Signal.
