G1 Cell Cycle Arrest

Saccharomyces cerevisiae Ste5 is a scaffold protein that recruits many pheromone signaling molecules to sequester the pheromone pathway from other homologous mitogen-activated protein kinase pathways. G1 cell cycle arrest and mating are two different physiological consequences of pheromone signal transduction and Ste5 is required for both processes. However, the roles of Ste5 in G1 arrest and mating are not fully understood. To understand the roles of Ste5 better, we isolated 150 G1 cell cycle arrest defective STE5 mutants by chemical mutagenesis of the gene. Here, we found that two G1 cell cycle arrest defective STE5 mutants (ste5MD248V and ste5delta-776) retained mating capacity. When overproduced in a wild-type strain, several ste5 mutants also showed different dominant phenotypes for G1 arrest and mating. Isolation and characterization of the mutants suggested separable roles of Ste5 in G1 arrest and mating of S. cerevisiae. In addition, the roles of Asp-248 and Tyr-421, which are important for pheromone signal transduction were further characterized by site-directed mutagenesis studies.Key words: Ste5, Saccharomyces cerevisiae, signal transduction, mating, G1 cell cycle arrest.

Barringtonia asiatica, is traditionally used as a medicinal plant in the Philippines; unfortunately, there is limited evidence supporting its anticancer capability. Thus, our study investigated the cytotoxic effect of B. asiatica seed extract against ovarian carcinoma A2780 (ECACC 93112519) and Saccharomyces cerevisiae as a cancer model organism. Seeds of B. asiatica were freeze-dried and extracted with methanol. The seed extract was investigated for its effect on the cell cycle in S. cerevisiae by utilizing yeast budding experiment and imaging flow cytometry. Its cytotoxicity activity was also tested as well as a live/dead assay was conducted against ovarian cancer cells. Findings revealed the anticancer activity of B. asiatica and its capability to induce G1 cell cycle arrest in S. cerevisiae. Thus, B. asiatica seeds may serve as a potential source of natural compounds towards anticancer drug discovery.
