MetabolomicsSpatially-guided metabolomics profiling of heterogeneous human tumor tissues

Bulk high-resolution mass spectrometry can provide sensitive and global snapshots of metabolites involved in cancer metabolism. However, intra-tumor heterogeneity (IntraTH) convolutes the cellular origins and tumor pathologies associated with the detected metabolites, thus making the elucidation ...

MetabolomicsHERPES SIMPLEX VIRUS TYPE 1 IMPAIRS DENDRITIC CELL FUNCTION BY REMODELLING NEUTRAL LIPID METABOLISM AND INDUCING LIPID DROPLET ACCUMULATION
Herpes simplex virus type 1 (HSV-1) infects dendritic cells (DCs), professional antigen-presenting cells that initiate and regulate host antiviral responses. HSV-1 infects DCs limiting their maturation, migration to draining lymph nodes and T cell activation capacity, ultimately promotes their apopt...

TranscriptomicsCommon and overlapping oncogenic pathways contribute to the evolution of acute myeloid leukemias
Recently, it has been demonstrated that transcriptionally active leukemia-associated fusion oncogenes alter self-renewal in and generate acute myeloid leukemia (AML) from committed progenitors, linking transformation and self-renewal pathways. AML is a heterogeneous disease, both genetically and bio...

TranscriptomicsChIP-chip with antibodies for histone 3 lysine 4 trimethylation, histone 3, and PolII in Mll1+/+ and Mll1-/- MEFs
Global analysis of H3K4 methylation defines MLL family member targets and points to a role for MLL1-mediated H3K4 methylation in the regulation of transcriptional initiation by RNA polymerase II A common landmark of activated genes is the presence of trimethylation on lysine 4 of histone H3 (H3K4) ...

TranscriptomicsBase and acid resistance of B. subtilis associated with transcriptomic responses
Gene expression profiles of Bacillus subtilis strain AG174 were compared as a function of steady-state external pH during growth with aeration. Aerated overnight cultures were diluted 1:500 and incubated in 250 mL baffled flasks containing potassium-modified Luria-Bertani medium (LBK) buffered with ...

TranscriptomicsThe global gene expression profile of gain of function miR34c in osteoblast
To examine the unbiased global gene expression of gain of miR34c in committed osteoblast in mouse we have performed expression microarray. This approach will allow us to define the novel targets that are negatively regulated by over-expression of miR34c in osteoblast. Total RNA was isolated from pri...

TranscriptomicsmiR-122 as a Regulator of Mitochondrial Metabolic Gene Network in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths worldwide, reflecting the need for a better understanding of hepatocarcinogenesis. In this study, we examined the genome-wide expression profiles of both miRNAs and mRNAs from paired tumor and adjacent non-tumor tissues fro...

TranscriptomicsBenzoate induced transcriptomic response in Bacillus subtilis
Bacillus subtilis strain AG174 was grown in the presence and absence of benzoate (30 mM). Benzoate was used in order to equalize the external and internal pH. The cultures were grown at external pH 7.0, and the addition of benzoate did not change the external pH. Microarray analysis was performed o...

TranscriptomicsHuman epidermal keratinocytes treated with retinoic acid or thyroid hormone
Targets of Retinoic Acid (RA) were identified in primary human epidermal keratinocytes grown in the presence or absence of all-trans retinoic acid for 1, 4, 24, 48 and 72 hours. Targets of Thyroid Hormone (T3) were identified in primary human epidermal keratinocytes grown in the presence or absenc...
