Taranukha D, et al. (2012) Co-regulation of polar mRNA transport and lifespan in budding yeast Saccharomyces cerevisiae. Cell Cycle 11(22):4275-80
Abstract: Recent studies have uncovered the links between aging, rejuvenation and polar protein transport in the budding yeast Saccharomyces cerevisiae. Here, we examined a still unexplored possibility for co-regulation of polar mRNA transport and lifespan. To monitor the amount and distribution of mRNA-containing granules in mother and daughter cells, we used a fluorescent mRNA-labeling system, with MFA2 as a reporter gene. The results obtained showed that deletion of the selected longevity regulators in budding yeast had a significant impact on the polar mRNA transport. This included changes in the amount of mRNA-containing granules in cytoplasm, their aggregation and distribution between the mother and daughter cells. A significant negative correlation was found between strain-specific longevity, amount of granules and total fluorescent intensity both in mother and daughter cells. As indicated by the coefficient of determination, approximately 50-75% of variation in yeast lifespan could be attributed to the differences in polar mRNA transport.
