Quantitative Phosphoproteomics of whole-body sponge collapse

Project description:Sponges (Porifera) are early-branching Metazoa who do not possess muscles or neurons, however are able to undergo a whole-body movement that involves the closure of their canal system and collapse of an epithelial tent. In this study we profile the proteomic responses of the freshwater sponge Spongilla lacustris during nitric oxide (NO) and agitation induced movements to elucidate the early evolution of coordination in animals. Specifically, we used tandem mass tag (TMT) labeling-based quantification of enriched phosphopeptides to systematically measure quantitative differences in protein phosphorylation. We identified and quantified 12165 unique phosphopeptides in the sponge. NO treatment resulted in quantitative changes of phosphorylation levels on 390 unique phosphopeptides mapping to 270 unique proteins. In turn, agitation led to quantitative changes of phosphorylation levels on 303 unique phosphopeptides (229 proteins).

The Role of Histone Modifications in Chromatin-Mediated Transcriptional Repression in the Protozoan Parasite Trichomonas vaginalis [ChIP-Seq]

Project description:Trichomonas vaginalis is an extracellular flagellated protozoan responsible for trichomoniasis, one of the most prevalent non-viral sexually transmitted infections. To persist in the host, T. vaginalis employs sophisticated gene regulation mechanisms to adapt to hostile environmental conditions. Although transcriptional regulation is crucial for this adaptation, the specific molecular mechanisms remain poorly understood. Epigenetic regulation, particularly through histone modifications, has emerged as a key modulator of gene expression. Our previous study demonstrated the role of histone modifications H3K4me3 and H3K27Ac in promoting active transcription. However, the full extent of epigenetic regulation in T. vaginalis remained unclear. In this study, we extend these findings by exploring the repressive role of two additional histone H3 modifications, H3K9me3 and H3K27me3. Genome-wide analysis reveals that these modifications are negatively correlated with gene expression, impacting not only protein-coding genes but also repeat genes and transposable elements. These findings offer new insights into the dual role of histone modifications in both activating and repressing gene expression, providing a more comprehensive understanding of epigenetic regulation in T. vaginalis. This expanded knowledge could inform the development of novel therapeutic strategies targeting the epigenetic machinery of this parasite.
