Project description:This is the first genome-scale model of G. dulcis, an extremely desiccation-tolerant cyanobacterium isolated from the Atacama desert by Azua-Bustos et al. (2014). We sequenced, closed, and annotated the G. dulcis genome, and created the model using KBase, and COBRApy. We included cyanobacterium-based photosynthesis reactions based on Toyoshima et al. (2020).
Project description:Bryophytes comprise mosses, liverworts and hornworts. The chromatin landscapes of mosses and liverworts are different, leaving open the question regarding the identity of the chromatin landscape of all bryophytes. To address this question we obtained a genome wide profile of 5-methylated cytosine from a model hornwort, Anthoceros agrestis.
Project description:Previous molecular and mechanistic studies have identified several principles of prokaryotic transcription, but less is known about the global transcriptional architecture of bacterial genomes. Here we perform a comprehensive study of a cyanobacterial transcriptome, that of Synechococcus elongatus PCC 7942, generated by combining three high-resolution data sets: RNA sequencing, tiling expression microarrays, and RNA polymerase chromatin immunoprecipitation (ChIP) sequencing. We report absolute transcript levels, operon identification, and high-resolution mapping of 5' and 3' ends of transcripts. We identify several interesting features at promoters, within transcripts and in terminators relating to transcription initiation, elongation, and termination. Furthermore, we identify many putative non-coding transcripts. We provide a global analysis of a cyanobacterial transcriptome. Our results uncover insights that reinforce and extend the current views of bacterial transcription.

Project description:Ganoderma colossum (Fr.) Baker, a white rot fungus distributed in tropical and subtropical forests, is a rare Ganoderma mushroom belonging to the family Ganodermataceae. In Asia, the fruiting body of G. colossum has been used as tonics or as folk medicine for a variety of illnesses, including malignant diseases. Colossolactone H (colo H) as a new compound was isolated and studied for its anticancer mechanism in human lung cancer H1650 cells. We used microarrays to analyze the gene expression changes upon colo H treatment that helped underlying the molecular mechanism of colo H in H1650 lung cancer cells.
Project description:Comprehensive proteomic dataset of cerebrospinal fluid (CSF) microvesicles. The aim of this study is to deeply characterize the protein content of microvesicles (MVs) isolated from human cerebrospinal fluid. MVs were isolated from Two CSF pools and their proteome was studied with high sensitivity mass spectrometry, electron microscopy and western blot.
