Project description:High-density neutrophils (HDNs), mature low-density neutrophils (M-LDN), and immature low-density neutrophils (IM-LDN) were isolated from peripheral blood of nine treatment-naïve colorectal cancer (CRC) patients with histologically confirmed diagnoses, followed by gene expression profiling of these neutrophil subsets using Digital RNA with pertUrbation of Genes (DRUG) sequencing.

Project description:ATAC sequencing of primary human monocytes cultured at low and high density. Monocytes isolated from PBMCs of 3 healthy donors were cultured at low density (1 x 10^6 cells/mL) or at high density (1 x10^7 cells/mL) for 24hrs and harvested for ATAC sequencing. Protein expression of FcgR2b is higher on monocytes in high density conditions compared to low density conditions, where expression is negligble. This study provides information on genome-wide chromatin accessibility changes that occur in high density culture in order to study associations with FcgR2b expression.
Project description:Previous studies have suggested an erasure of DNA methylation is required to develop the stem cells in the morula embryo. An exception involves imprinted genes that escape this DNA methylation erasure. Transgenerational differential DNA methylation regions (DMRs) have been speculated to also escape this erasure. The current study was designed to assess if morula embryos escape erasure of DDT (dichloro-diphenyl-trichloroethane)-induced transgenerational sperm DMRs. Observations demonstrate that the transgenerational sperm DMR sites are not erased, so are imprinted-like DMR sites. Interestingly, we also found that the majority of low-density CpG genomic sites had a significant increase in DNA methylation in the morula embryo compared to sperm. The general erasure of DNA methylation during embryogenesis appears applicable for high-density CpG islands, but not low-density CpG deserts.

Project description:Lymphomas are classified according to the World Health Organization (WHO) classification which defines subtypes on the basis of clinical, morphological, immunophenotypic, molecular and cytogenetic criteria. Using this model, 8 of 9 of the validation samples were classified successfully. This pilot study demonstrates that such a microarray tool may be a promising diagnostic approach for small B-cell non-Hodgkin’s lymphoma.
