TranscriptomicsCathepsin K Contributes to Cavitation and Collagen Turnover in Pulmonary Tuberculosis
Cavitation in tuberculosis (TB) enables highly efficient person-to-person aerosol transmission. Currently, a number of hypotheses exist regarding the mechanisms underlying this process. To explore this process, we undertook an unbiased next-generation transcriptional analysis of samples from cavity ...

TranscriptomicsChromatin immunoprecipitation of human erythroleukemia cell line K-562 with H3K4me2, H3K4me3, H3ac, H4ac, Histone H2B and Histone H3 antibodies using an ENCODE array
ENCODE ChIP-chip study using human myelogenous leukemia cell line K-562 and anti histone H3K4me2 (Abcam; ab7766); H3K4me3 (Abcam; ab8580); H3ac (Upstate; 06-599); H4ac (Upstate; 06-866); Histone H2B (Abcam: ab1790) and Histone H3 (Abcam: ab1791) antibodies. Each antibody experiment was conducted in ...

TranscriptomicsMacrophages recognize the Helicobacter pylori type IV secretion system in the absence of TLR signaling
Helicobacter pylori conquered the world by colonizing the human stomach. There are two major groups of strains, one with and one without a cag pathogenicity island (cagPAI), which result in different clinical outcomes with increased severity in cagPAI+ H. pylori infections such as higher inflammatio...

TranscriptomicsDNA microarray analysis of genes positively regulated by HapR
Vibrio cholerae strains A1552 and ATN140 (A1552-delta-hapR) were diluted 1:100 from over night cultures and grown aerobically (at 250 rpm) in M9 minimal medium supplemented with vitamins (MEM vitamin solution, BRL) and 0.5% lactate. At OD600 ~ 0.3 2 mM (GlcNAc)6 (Seikagaku America, East Falmouth, MA...

TranscriptomicsCaste-specific expression patterns of olfactory related genes in the leaf-cutting ant, Atta vollenweideri
To allow estimation of the complexity and gene expression differences of the antennal transcriptome between sexes as well as between castes, microarrays were designed based on an assembly of A. vollenweideri antennal sequence data from all sexes and castes. The microarrays were hybridized with sampl...

TranscriptomicsNID2 and HOXA9 promoter hypermethylation as biomarkers to prevent and detect Oral Cavity Squamous Cell Carcinoma
Differentially methylated oral squamous cell carcinoma (OSCC) biomarkers, identified in-vitro and validated in well-characterized surgical specimens, have shown poor clinical correlation in cohorts with different risk profiles. To overcome this lack of relevance we used the HumanMethylation27 BeadCh...

GenomicsThe PhoP-dependent ncRNA Mcr7 modulates the TAT secretion system in Mycobacterium tuberculosis [ChIP-Seq]
The PhoPR two-component system is essential for virulence in Mycobacterium tuberculosis where it controls expression of approximately 2% of the genes, including those for the ESX-1 secretion apparatus, a major virulence determinant. Mutations in phoP lead to compromised production of pathogen-specif...

TranscriptomicsPlag1 overexpression cooperates with Evi1 overexpression and Gata1s mutation in leading to M7 leukemia
The goal of this study is to develop a Plag1 signature and determine how its overexpression contributes to leukemogenesis. To study this, we transduced an immortalized (but not transformed) cell line (derived from Gata1s mutant fetal liver progenitor through insertional mutagenesis) by Plag1-expres...

GenomicsChronic growth factor signaling in Acute Myeloid Leukemia is connected to a specific chromatin signature [ChIP-Seq]
We performed genome-wide DNaseI hypersensitive site in FLT3-ITD and WT patient samples. We report corresponding gene expression, promoter methylation patterns of differential DHSs as well as differentially occupied TF binding motifs using surrounding DNAseI cut profiles. We examined association patt...
