TranscriptomicsLymphoid Priming in Human Bone Marrow Begins Prior to CD10 Expression with Up-Regulation of L-selectin
Studies of adult human hematopoiesis have until now relied on the expression of CD10 to define lymphoid commitment. We report a novel lymphoid-primed population in human bone marrow that is generated from hematopoietic stem cells (HSC) prior to the onset of CD10 expression and B cell commitment, and...

TranscriptomicsComparative analysis of transcripts associated with all-stage resistance to stripe rust in wheat
Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a destructive disease of wheat worldwide. Genetic resistance is the preferred method for controlling stripe rust, of which two major types are race-specific and race non-specific resistance. Race-specific resistance includes the qualitat...

TranscriptomicsDiscovery of novel imprinted genes by transcriptional analysis of parthenogenetic embryonic stem cells
Parthenogenetic embryonic stem cells (PESCs) may have future utility in cell replacement therapies. We examined genome-wide mRNA expression profiles of monkey PESCs relative to ESCs derived from fertilized embryos. Several known paternally-imprinted genes were in the highly down-regulated group in P...

MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

ProteomicsTargeted inhibition of human breast cancer cell lines selected as model systems of ERBB2-positive/EGFR high breast cancer [RPPA-SKBR3]
EGFR-inhibition is required for targeted therapies of ERBB2-positive/EGFR high breast cancer. Approximately 30% of human ERBB2-positive breast tumors also express EGFR. Three targeted therapeutics (erlotinib, pertuzumab, trastuzumab) and two ligands (EGF, HRG) were analyzed in all possible combinati...

MetabolomicsCell overgrowth potentiates osmotic and replication stresses to promote p38/p53/p21-dependent senescence
Abnormal increases in cell size are associated with senescence and cell cycle exit. The mechanisms by which overgrowth primes cells to withdraw from the cell cycle remain unknown. We address this question using CDK4/6 inhibitors, which arrest cells in G0/G1 and are licensed to treat advanced HR+/HER...

TranscriptomicsSolar simulated ultraviolet radiation induces histone 3 methylation changes in the gene promoters of matrix metalloproteinases 1 and 3 in primary human dermal fibroblasts [II]
Skin damage from solar ultraviolet radiation (UVR) accumulates in the dermal extracellular matrix (ECM) and contributes to photoaging. Following UVR exposure, matrix metalloproteinases (MMPs) are secreted by dermal fibroblasts to repair and remodel the ECM. Molecular signaling pathways delineating t...

TranscriptomicsTranscription profiling of human platelets from patients with essential thrombocythemia
Human blood platelets have important, regulatory functions in diverse hemostatic and pathological disorders, including vascular remodeling, inflammation, and wound repair. Microarray analysis was used to study the molecular basis of essential thrombocythemia, a myeloproliferative disorder with quant...

TranscriptomicsTranscription profiling of rat mast cells from diabetic prone and diabetic resistant strains
Abstract; Human type 1 diabetes mellitus (T1DM) arises through autoimmune destruction of pancreatic β cells and is modeled in many respects by the lymphopenic and spontaneously diabetic BioBreeding (BB) DRlyp/lyp rat. Previously, pre-onset expression profiling of whole DRlyp/lyp pancreatic lymph...

TranscriptomicsExpression profiling of skeletal muscle in beef cattle treated with steroidal growth promoters
In the present study, a oligonucleotide microarray platform is used to compare expression profiles of beef cattle muscle in animals treated with either Dexamethazone (Dex) or Dexamethazone plus 17?-estradiol (Estr) administered at sub-therapeutic dosage, against untreated controls. Seventeen male be...
