Description
Purpose: Lithium salts, used for treatment of bipolar disorder, frequently induce nephrogenic diabetes insipidus (NDI), limiting therapeutic success. NDI is associated with loss of expression of the molecular water channel, aquaporin-2, in the renal collecting duct (CD). Here, we use the methods of systems biology in a well-established rat model of lithium-induced NDI to identify signaling pathways activated at the onset of polyuria. Methods: We carried out RNA-sequencing in cortical CDs microdissected from rats treated with lithium for 12-72 hours (vs. time controls). Administration of anti-inflammatory doses of dexamethasone to lithium-treated rats countered the loss of aquaporin-2 protein. Protein mass spectrometry in microdissected cortical CDs provided corroborative evidence, but also identified decreased abundance of several anti-oxidant proteins. Cortical thick ascending limbs of Henle were also microdissected for RNA-Seq at 72 hrs. We carried out RNA-Seq for 2-3 CCD sample per rat (1 lithium-treated rat versus 1 control at 12, 24, 36 hrs). Results and conclusion: Integration of new data with prior data about lithium effects at a molecular level leads to a signaling model in which lithium increases ERK activation leading to induction of NF-?B signaling and an inflammatory-like response that represses Aqp2 gene transcription. Overall design: We carried out RNA-sequencing and protein mass spectrometry in cortical CDs microdissected from rats treated with lithium. We identified signaling pathways that initiate Lithium-induced NDI using systems biology approaches.

Description
Here we show that hematopoietic transcription factors Scl, Lmo2, Runx1 and Bmi1 can convert a developmentally-distant lineage (fibroblasts) into induced hematopoietic progenitors (iHPs). We analyzed transcriptomic data for cell undergoing the transdifferentiation process at several time-points of the process.

Description
The EMT program allows epithelial cells to become endowed with motility, invasiveness and stem cell traits. We investigated difference in signaling networks that are differentially utilized in EMTed and non-EMTed cells, thereby identifying therapeutic targets that are unique to EMT/cancer stem cells.

Description
Circulating tumor cells (CTCs) are the subject of several translational studies and clinical trials because their examination could offer an insight into tumor progression and clinical outcomes. Circulating tumor microemboli (CTM) are clusters of CTCs that have been described as malignant entities for over 50 years, although a comprehensive characterization of these cells is still lacking. Contrary to current consensus, we demonstrate that CTM isolated from colorectal cancer patients are not cancerous, but represent a discrete population of tumor-derived endothelial cells. CTM express epithelial and mesenchymal markers that are consistent with previous reports on circulating tumor cell phenotyping. However, they do not mirror the genetic variations of matching tumors. Transcriptome analysis of single-CTM reveals that these structures exhibit an endothelial phenotype, with further results supporting a tumor-derived endothelial lineage. CTM are widespread in blood sampled from preoperative cancer patients but not in healthy donors, suggesting CTM count as a potential biomarker of interest for colorectal cancer. CTM should not be confused with bona fide circulating epithelial tumor cells. The characterization of tumor derived endothelial cell clusters (TECCs) is likely of high diagnostic value, and may provide direct information about the underlying tumor vasculature at the time of diagnosis, during treatment and the course of the disease. Overall design: Profiling of 18 TECCs/CTM from 8 colorectal cancer patients. In addition profiling of matched 7 normal colonic mucosa, 9 primary colorectal tumor samples (of which three from the same patient), one colorectal cancer metastatis. Additionally, 14 laser-capture-dissected endothelia from the same patients and tissues, and 3 commercially available normal endothelial cell lines
