Abstract
The transcriptional coactivators YAP (Yes-associated protein) and TAZ (transcriptional coactivator with PDZ-binding motif) are the main downstream effectors of the evolutionary conserved Hippo signaling pathway. YAP/TAZ is implicated in the transcriptional regulation of target genes that are involved in a wide range of key biological processes affecting tissue homeostasis and play dual roles in the aging process depending on cellular and tissue context. The aim of the present study was to investigate whether pharmacological inhibitors of Yap/Taz may increase the lifespan of Drosophila melanogaster. qRT-PCR was performed to measure the changes in the expression level of Yki (Yorkie, the Drosophila homolog of YAP/TAZ) target genes. We have revealed a lifespan increasing effect of YAP/TAZ inhibitors that was mostly associated with decreased expression level of wg and E2f1 genes. However further analysis is required to understand how YAP/TAZ pathway is linked with aging.
