Project description:We analyze and report the differences in gene expression between de novo NEPC and ARPC using spatial gene expression analysis techniques (Visium CytAssist, 10x genomics).
Project description:These data were used in the spatial transcriptomics analysis of the article titled \\"Single-Cell and Spatial Transcriptomics Analysis of Human Adrenal Aging\\".
Project description:To investigate spatial heterogeneities in the axolotl forebrain, a coronal section of it was obtained for spatial transcriptomics using Visium V1.
Project description:Spatial organization of different cell types within prenatal skin across various anatomical sites is not well understood. To address this, here we have generated spatial transcriptomics data from prenatal facial and abdominal skin obtained from a donor at 10 post conception weeks. This in combination with our prenatal skin scRNA-seq dataset has helped us map the location of various identified cell types.
Project description:In plants, maintenance-methylation mediated by METHYLTRANSFERASE-1 (MET1), siRNA-directed de-novo methylation, and chromatin remodeling by DECREASE IN DNA METHYLATION -1 (DDM1) promote transcriptional gene-silencing of transposable elements (TEs). This process is mostly investigated at steady states reflecting how long-established silent conditions are maintained, faithfully re-iterated or temporarily modified during growth, stress and over generations. How invasive TEs are detected and silenced de novo, however, remains largely unknown. Using inbred lineages of hybrid Arabidopsis epigenomes combining wild-type and met1 or ddm1 chromosomes, we have deciphered the timing, spatial distribution and mechanisms underpinning the proliferation and eventual demise of the endogenous retrotransposon évadé (EVD). Both developmental and molecular features of EVD biology, including a remarkable ability to evade RNA interference, ultimately contribute to its silencing over multiple generations. The underlying processes are accompanied by widespread diversification of the Arabidopsis genome and de-novo epiallelism creating an extensive reservoir of selectable and potentially adaptive traits.
