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 have been treated together with the indicated concentrations of -factor for 90 min, and then -galactosidase activity was measured. Information are suggests SEM from 3 experiments, every performed in quadruplicate. Information are expressed as a percentage from the -galactosidase activity of WT cells in the maximum concentration of pheromone.

Crosstalk amongst mating and glucose-sensing pathways(A to C) Analysis on the effects of high and low glucose around the abundance and phosphorylation of Fus3. (A) WT cells, (B) elm1sak1tos3 cells, and (C) reg1 cells have been cultured in medium containing two or 0.05 glucose for 5 min ahead of becoming left IL-2, Human untreated or treated with three -factor (-F) for the indicated times prior to they were harvested for evaluation. Prime: Samples have been analyzed by Western IL-10 Protein medchemexpress blotting with antibody against phosphorylated p4442 MAPK (to detect p-Fus3 and p-Kss1), also as with antibodies particular for total Fus3, Gpa1, phosphorylated Snf1 (p-Snf1), and G6PDH, which was utilised as a loading handle. Middle: Densitometric evaluation from the abundance of p-Fus3. Bottom: Densitometric analysis of your abundance of total Fus3. For densitometric analysis, essentially the most intense band on every blot was set at 100 , plus the intensities of the other bands were expressed as percentages of the maximum. Results are suggests SEM from 3 independent experiments.

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