GenomicsCUT&RUN chromatin profiling of H3K4me3, H3K27ac and H3K9me3 histone marks in spermatids and spermatocytes
Spermatogenesis is a recurring differentiation process that results in the production of male gametes within the testes. During this process, spermatogonial stem cells differentiate to form spermatocytes, which undergo two rounds of meiotic division to form haploid spermatids. Throughout spermiogene...

TranscriptomicsHistone H2A.Z and DNA methylation are mutually antagonistic chromatin marks
Eukaryotic chromatin is separated into functional domains differentiated by posttranslational histone modifications, histone variants, and DNA methylation. Methylation is associated with repression of transcriptional initiation in plants and animals, and is frequently found in transposable elements...

TranscriptomicsMicroRNAs mediate rapamycin resistance in a myogenic tumor cell line
The mammalian target of rapamycin (mTOR) is a central regulator of cell proliferation. Inhibitors of mTOR are being evaluated as anti-tumor agents. Given the emerging role of microRNAs (miRNAs) in tumorgenesis we hypothesized that miRNAs could play important roles in the response of tumors to mTOR i...

TranscriptomicsDCLK1 Marks a Morphologically Distinct Subpopulation of Cells with Stem Cell Properties in Pre-invasive Pancreatic Cancer
As in other tumor types, progression of pancreatic cancer may require a functionally unique population of cancer stem cells. Although such cells have been identified in many invasive cancers, is not clear whether they emerge during early or late stages of tumorigenesis. Using mouse models and human ...

GenomicsChIP-seq of CIC (Capicua) and histone marks (H3K9ac, H3K27ac and H3K4me1) in glioma neural stem cells (GNS) G144, human foetal neural stem cells (hNSC) and mouse embryonic stem cells (mESC),
We identified genome-wide binding patterns of CIC in several different cell types and find that CIC target genes are enriched for MAPK effector genes involved in cell cycle regulation and proliferation. CIC binding to its target genes is abolished by high MAPK activity, which leads to hyperacetylati...

TranscriptomicsVariation in DNA methylation patterns more common among maize inbreds than among tissues
Epigenetic marks such as DNA methylation can act as heritable marks on a genome leading to unique regulation of genomic sequences. As a transient mark, DNA methylation has been identified as a possible mechanism for reversible genetic regulation of cells derived through either mitotic or meiotic cel...

TranscriptomicsTranscriptome analysis of cuprizone mouse model following AAV-mediated delivery of A Proliferation Inducing Ligand
A Proliferation Inducing Ligand (APRIL) is a member of the tumour necrosis factor (TNF) superfamily and has recently been shown to modulate pro-inflammatory astrocyte responses, as well as to ameliorate disease outcome in the experimental autoimmune encephalomyelitis mouse model for multiple scleros...

TranscriptomicsSpreading of heterochromatin is limited to specific families of maize retrotransposons
Transposable elements have the potential to act as controlling elements to influence the expression of genes. The current paradigm suggests that heterochromatic silencing can spread beyond the borders of the transposable element and influence the chromatin state of neighboring low-copy sequences. ...
