Project description:While the unique symbiotic relationship between anemonefish and sea anemones is iconic, it is still not fully understood how anemonefish withstand and thrive within this venomous host environment. In this study we used a proteotranscriptomics approach to elucidate the proteinaceous toxin repertoire from the most popular host sea anemone Entacmaea quadricolor. Although 1251 different toxin or toxin-like RNA transcripts were expressed in E.quadricolor tentacles and 2736 proteins were detected in milked venom, only 135 (approx. 10%) of proteins in venom were classified as putative toxins. This work raises the perils of defining a dominant venom type based on transcriptomics data alone in sea anemones, as we found that the dominant venom type differed between the transcriptome and proteome data. Moreover, anemonefishes interact with sea anemone proteins, so it is important when determining the dominant toxin type to examine the peptides and proteins that are present in host sea anemone venom and mucus which anemonefishes are known to interact.

Project description:marine invertebrate-associated microbiomes are rich resources for prospecting novel genes and bioactive compounds. In a previous study, we isolated Streptomyces sp. SCSIO 001680, coded as strain 63, from the Red Sea nudibranch Chromodoris quadricolor, exhibits antimicrobial and antitumor activity.
Project description:Single cell Methylome and Transcriptome Sequencing (scM&T-Seq) was performed on index-sorted single CD48- CD135- Lin- Sca-1+ c-Kit+ cells from Scl-tTA; H2B-GFP mouse bone marrow after 100 days of chase. Methylation data is uploaded here.
Project description:C8orf33-proficient and deficient DIvA cells were treated with 4-hydroxy tamoxifen (4OHT) to induce DNA double strand breaks (DSB) at several loci within the human genome. following 4OHT treatment cells were subject to ChIP-seq analysis for KAT8 acetyltransferase to map its enrichment at DSB sites in C8orf33 proficient deficient cells.
