View SamplesRNA-Seq profiling of MCF-7 and MDA-MB-231. We profiled RNA expression in the estrogen-receptor-positive (ER+) MCF-7 and the triple-negative MDA-MB-231 breast cancer cells. The objective was to find genes differentially expressed between these cell lines as potential drivers of invasiveness of the triple-negative MDA-MB-231. We further utilized the identified differential genes to validate expression-responsive module of non-canonical Wnt signaling pathway. Overall design: 2 biological replicates of MCF-7 and 3 biological replicates of MDA-MB-231

View SamplesCircadian clocks are cell-autonomous oscillators regulating daily rhythms in a wide range of physiological, metabolic and behavioral processes. Conversely, metabolic signals such as redox state, NAD+/NADH and AMP/ADP ratios or heme feed back to and modulate circadian mechanisms to optimize energy utilization across the 24-hour cycle. We show that the signaling molecule carbon monoxide (CO) generated by rhythmic heme degradation is required for normal circadian rhythms as well as circadian metabolic outputs.

View SamplesRNA-Seq profiling of estrogen-receptor-positive MCF-7 cell lines with different perturbations of non-canonical WNT signaling . The MCF-7 cells were either transfected with an empty vector (pcDNA) or with a ROR2 overexpression construct, in parallel with or without stimulation with recombinant WNT5A. The objective was to find expression-responsive targets of these perturbations as potential drivers of increased cell invasiveness. Overall design: Four conditions of MCF-7 cells each in 3 replicates: 1. empty vector (pcDNA), 2. empty vector (pcDNA) with WNT5A stimulation, 3. ROR2 overexpression construct, 4. ROR2 overexpression construct with WNT5A stimulation

View SamplesFormation of organ-specific vasculatures requires cross-talk between developing tissue and specialized endothelial cells. Here we show how developing zebrafish spinal cord neurons coordinate vessel growth through balancing of neuron-derived Vegfaa, with neuronal sFlt1 restricting Vegfaa-Kdrl mediated angiogenesis at the neurovascular interface. Neuron-specific loss of flt1 or increased neuronal vegfaa expression promotes angiogenesis and peri-neural tube vascular network formation. Combining loss of neuronal flt1 with gain of vegfaa promotes sprout invasion into the neural tube. Upon loss of neuronal flt1, ectopic sprouts emanate from veins involving special angiogenic cell behaviors including nuclear positioning and a molecular signature distinct from primary artery or secondary venous sprouting. Manipulation of AV identity or Notch signaling established that ectopic sprouting in flt1 mutants requires venous endothelium. Conceptually our data suggest that spinal cord vascularization proceeds from veins involving two-tiered regulation of neuronal sFlt1 and Vegfaa via a novel sprouting mode. Overall design: Examination of wildtype (3 biological replicates, with two technical replicates each) and flt1ka601 homozygous mutants (3 biological replicates, with two technical replicates each)
Neuronal sFlt1 and Vegfaa determine venous sprouting and spinal cord vascularization.

View SamplesRecent efforts have uncovered immense transcriptional and ontogenetic diversity among tissue-resident macrophages, each with their own transcriptional profile endowing the cell with its tissue-specific functions. However, it is currently unknown whether the origins of different macrophage populations may affect their roles in malignancy. Given potential artifacts associated with irradiation-based lineage tracing, it remains unclear if bone marrow-derived macrophages (BMDM) are even present in tumors of the brain, a tissue where there is no homeostatic involvement of peripherally-derived myeloid cells. Here, we employed multiple models of murine brain malignancy and genetic lineage tracing models to demonstrate that BMDM are indeed abundant in primary and metastatic brain tumors. Transcriptional profiling of tumor-associated BMDM and resident microglia showed that these cells acquire substantially different gene expression profiles. Our data suggest that transcriptional networks in each cell population are associated with tumor-mediated education, yet are also influenced by chromatin landscapes established before tumor initiation. Furthermore, we demonstrate that microglia specifically repress Itga4 (CD49D), enabling its utility as a discriminatory marker between brain-resident microglia and peripherally-derived macrophages in both primary and metastatic disease in mouse and human. Overall design: Tumor associated microglia and macrophages were isolated from mouse glioma tumors. Samples are provided as matched microglia and macrophages from 3 tumors.
