Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
It is widely believed that the molecular and cellular features of a tumor reflect its cell-of-origin and can thus provide clues about treatment targets. The retinoblastoma cell-of-origin has been debated for over a century. Here we report that human and mouse retinoblastomas have molecular, cellular, and neurochemical features of multiple cell classes, principally amacrine/horizontal interneurons, retinal progenitor cells, and photoreceptors. Importantly, single-cell gene expression array analysis showed that these multiple cell typespecific developmental programs are coexpressed in individual retinoblastoma cells, which creates a progenitor/neuronal hybrid cell. Importantly, neurotransmitter receptors, transporters, and biosynthetic enzymes are expressed in human retinoblastoma, and targeted disruption of these pathways reduces retinoblastoma growth in vivo and in vitro. Our finding that retinoblastoma tumor cells express multiple neuronal differentiation programs that are normally incompatible in development suggests that the pathways that control retinal development and establish distinct cell types are perturbed during tumorigenesis. Therefore, the cell-of-origin for retinoblastoma cannot be inferred from the features of the tumor cells themselves. However, we now have a detailed understanding of the neuronal pathways that are deregulated in retinoblastoma and targeting the catecholamine and indolamine receptors or downstream components could provide useful therapeutic approaches in future studies. This example highlights the importance of comprehensive molecular, cellular and physiological characterization of human cancers with single cell resolution as we incorporate molecular targeted therapy into treatment regimens.

Description
Trans fatty acids (tFAs) may have deleterious, long-term transcriptional effects. To explore that issue, we assessed the effects of the tFA elaidic acid and its cis isomer oleic acid on transcription and, in parallel, on DNA methylation.

Description
Reverse genetics has been widely used to investigate function of viral genes. In the present study we investigated the gene expression profile of a primary ovine cell (OFTu) in response to infection with the wild type (OV-IA82) and deletion mutant virus (OV-IA82024) aiming to determine possible functions for ORFV024 during ORFV infection.

Description
We present ScarTrace, a single-cell sequencing strategy that allows us to simultaneously quantify information on clonal history and cell type for thousands of single cells obtained from different organs from adult zebrafish. Using this approach we show that all blood cells types in the kidney marrow arise from a small set of multipotent embryonic. In contrast, we find that cells in the eyes, brain, and caudal tail fin arise from many embryonic progenitors, which are more restricted and produce specific cell types in the adult tissue. Next we use ScarTrace to explore when embryonic cells commit to forming either left or right organs using the eyes and brain as a model system. Lastly we monitor regeneration of the caudal tail fin and identify a subpopulation of resident macrophages that have a clonal origin that is distinct from other blood cell types. Overall design: Single cell sequencing data from cells isolated from zebrafish organs (whole kidney marrow, forebrain, hindbrain, left eye, right eye, left midbrain, right midbrain, and regenerated fin). For each cell, we provide libraries with transcritpome and with clonal information, respectively.

Description
Expansion for hematopoietic cells from umbilical cord blood is a strategy for use this cell source in clinic transplants, however, it is important to know about the genomic changes that can occur in expanded cells. In order to detect global expression profiles changes in hematopoietic stem and progenitors cells generated in vitro, we analyzed hematopoietics populations obtained by FACS in fresh from umbilical cord blood. HSC (fHSC) was defined as CD34+ CD38- CD71- CD45RA- Lin- and were cocultured with stromal cell line OP-9 plus FL, SCF, IL3, IL6, TPO, GMCSF and G-CSF by 7 days, after time we repurified HSC population by FACS using same immunophenotype (ivHSC). In other hand, fresh erythroid progenitors cells (fEPC) were identified as CD34+CD38+CD71+CD45RA- Lin- and fresh myeloid progenitors cells (fMPC) were identified as CD34+CD38+CD71-CD45RA+Lin-. In vitro progenitors cells (ivEPC and ivMPC) were obtained by culturing fHSC in Stemspan serum-free media plus SCF, TPO, IL6, FL and IL3 by 10 days, after time cells were repurified by FACS using same immunophenotype for fresh progenitors. In vitro generated cells were compared with their corresponding fresh population cells.

Description
We generated and characterized an androgen-independent LNCaP-AI cell line by long-term culture of androgen-dependent LNCaP cells in RPMI-1640 medium containing charcoal-stripped serum. This approach used to generate the line mimics the castration resistant condition for treating prostate cancer, supporting the relevance of the LNCAP-AI cell line to Castration Resistant Prostate Cancer. Overall design: LNCaP-AI cells transfected with lncRNA PCAT1 shRNA and the scramble shRNA were used for the RNA-seq.
