Background:

Yeast (Saccharomyces cerevisiae) is a key genetic model organism.
Previous research on yeast cell death primarily focused on survival outcomes, not mechanisms.
Mammalian cell death assays are not readily applicable to yeast.

Purpose of the Study:

To develop a novel cell death assay for Saccharomyces cerevisiae.
To identify genes regulating yeast cell death pathways.
To bridge the gap in understanding yeast cell death mechanisms.

Main Methods:

A precisely controlled heat ramp applied to yeast suspensions.
Quantification of cell death using high-throughput automated analyses.
Application to screen chemical libraries for effects on yeast genes.
