Project description:We characterized the mouse trophoblast giant cell epigenome and gene expression profiles. We then compared these data to our data on underrepresentation in the polyploid trophoblast giant cells. We profiled 5 histone modifications (+ chromatin input) using ChIP-Seq, and digital expression profiles (3' RNA-Seq) for trophoblast giant cells derived from mouse. Furthermore, we profiled digital expression profiles (3' RNA-Seq) for in vivo trophoblast giant cells samples from e9.5 wildtype mouse trophoblast giant cells. We found that underrepresented domains in trophoblast giant cells are enriched for repressive marks and anti-correlate with active marks and transcription.

Project description:We present a draft genome assembly that includes 200 Gb of Illumina reads, 4 Gb of Moleculo synthetic long-reads and 108 Gb of Chicago libraries, with a final size matching the estimated genome size of 2.7 Gb, and a scaffold N50 of 4.8 Mb. We also present an alternative assembly including 27 Gb raw reads generated using the Pacific Biosciences platform. In addition, we sequenced the proteome of the same individual and RNA from three different tissue types from three other species of squid species (Onychoteuthis banksii, Dosidicus gigas, and Sthenoteuthis oualaniensis) to assist genome annotation. We annotated 33,406 protein coding genes supported by evidence and the genome completeness estimated by BUSCO reached 92%. Repetitive regions cover 49.17% of the genome.

Project description:Giant cell granulomas of the jaws often occur sporadically as single central or peripheral lesions. They are characterized by KRAS, FGFR1, or TRPV4 somatic mutations, the latter occurring exclusively in the central form. Less commonly, multiple giant cell lesions can develop in the context of syndromes such as cherubism, which is an autosomal dominant bone disease. Morphologically, giant cell granulomas can closely resemble other giant cell-rich lesions such as non-ossifying fibroma and aneurysmal bone cyst, and to a minor extent giant cell tumour of bone and chondroblastoma. The epigenetic basis of these giant cell-rich tumours is unclear and, recently, DNA methylation profile has been shown to be clinically useful for the diagnosis of other tumour types, including brain tumours as well as bone and soft tissue sarcomas. Therefore, we aimed to assess the DNA methylation profile of central and peripheral sporadic giant cell granulomas of the jaws and cherubism to test whether DNA methylation patterns can help to distinguish these entities. Additionally, we further compared the DNA methylation profile of these lesions with those of other giant cell-rich mimics to investigate if the microscopic similarities extend to the epigenetic level. Our results showed that central and peripheral sporadic giant cell granulomas of the jaws and cherubism share a related DNA methylation pattern with that of peripheral sporadic giant cell granulomas and cherubism appearing slightly distinct, while central sporadic giant cell granulomas show overlap with both of the former. Non-ossifying fibroma, aneurysmal bone cyst, giant cell tumour of bone, and chondroblastoma, on the other hand, have distinct methylation patterns. Therefore, DNA methylation profiling is currently not capable of clearly distinguishing sporadic and cherubism-associated giant cell lesions of the jaws. Conversely, it could discriminate sporadic giant cell granulomas from their giant cell-rich mimics.
