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 with the indicated concentrations of -factor for 90 min, and after that -galactosidase activity was measured. Data are signifies SEM from three experiments, every performed in quadruplicate. Information are expressed as a percentage of the -galactosidase activity of WT cells at the maximum concentration of pheromone.

Crosstalk amongst mating and glucose-sensing pathways(A to C) Evaluation on the effects of higher and low glucose on the abundance and phosphorylation of Fus3. (A) WT cells, (B) elm1sak1tos3 cells, and (C) reg1 cells were cultured in medium containing 2 or 0.05 glucose for five min before being left untreated or treated with three -factor (-F) for the indicated occasions just before they had been harvested for evaluation. Leading: Samples were analyzed by Western blotting with antibody against phosphorylated p4442 MAPK (to detect IL-8 Compound p-Fus3 and p-Kss1), at the same time as with antibodies certain for total Fus3, Gpa1, phosphorylated Snf1 (p-Snf1), and G6PDH, which was utilised as a loading handle. Middle: MCT4 list Densitometric analysis on the abundance of p-Fus3. Bottom: Densitometric evaluation of the abundance of total Fus3. For densitometric analysis, one of the most intense band on every blot was set at 100 , along with the intensities of the other bands were expressed as percentages on the maximum. Outcomes are signifies SEM from three independent experiments.

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

Separate cultures of WT mating-type a cells (BY4741) and WT mating-type cells (BY4742) had been grown in medium containing two glucose. Cells (1 107) f.
