Project description:CD44+/CD24- subpopulation of normal and cancerous breast epithelial cells are suggested to have stem cell properties. The goal of this study was to identify gene expression differences between CD44+/CD24- and CD44-/CD24+ subpopulation of cells from a same cell lines. We selected MCF-10A cells, which are immortalized derived from a fibrocystic breast disease. These cells are immortalized but not transformed and express basal cell markers. Cells were from a single sort but plated into four 100 mm plates. RNA was prepared from each plate separately for the analysis. Comparison of gene expression between 2 groups ( CD44+/CD24- and CD44-/CD24+) 4 replicates each.

Project description:Being involved in adhesion, migration, and invasion, the highly glycosylated signal transducer CD24 (cluster of differentiation 24) has been implicated to play an essential role during carcinogenesis. Previously, the molecular and (epi)genetic regulation of CD24 has been characterized in testicular germ cell tumors (GCT). Here, CD24 was exclusively found in embryonal carcinoma (EC), which represents the stem cell like population of GCT (see project PXD025110). For a better understanding of the molecular function of CD24, this study aimed at the identification of the direct interaction partners of CD24 not only in GCTs, but also in other urologic malignancies, such as urothelial- (UC), prostate- (PC), and renal cell carcinoma (RCC). For this purpose, co-immunoprecipitations of CD24 were performed in GCT, UC, PC, and RCC cell lines, while CD24-deficient EC cells as well as IgG2a controls were included for high validity. Extracted proteome was measured by liquid-chromatography coupled with mass spectrometry (LS-MS).

Project description:To understand the role of p53 in regulating stem cell population (CD24-CD44+) and stemness-associated miRNAs, we first compared miRNA expression profiles between human mammary epithelical cells knocked-down p53 and control cells. We then cross-referenced p53-regulated miRNAs with stemness-associated miRNAs analyzed from expression profiling of sorted CD24-CD44+ and non-CD24-CD44+ cell populations. Further biological experiments were performed with the miRNAs that are altered in CD24-CD44+ stem cell populations and also regulated by p53. Total RNAs, including miRNAs, extracted from CD24-CD44+ cells (labeled in Hy3) and non-CD24-CD44+ cells (labeled in Hy5) were hybridized on Exiqon miRCURY LNA arrays according to the manufacturer's protocol.

Project description:Analysis of stage-specific gene expression in Zbtb46GFP/+ pre-CD8 DCs, pre-CD4 DCs, CD24 cDCs and CD172a cDCs Bone Marrow and Splenocytes were harvested from 8-10 littermate Zbtb46GFP/+ mice and sorted to >95% purity on the FACS AriaFusion.

Project description:Our aim is to identify genes that play important role to cell proliferation in PDAC. Lentivirus shRNA library was transduced to CAPAN2 cells. The cells were orthotopically injected into nude the pancreas of the mice. Tumors were allowed to grow and subsequently total RNA was extracted from the tumor tissues. The differential level of shRNA between tumor cells and uninjected cells were compared.

Project description:KPR tumors were subcutaneously implanted in Lrrc15DTRGFPwt/wt (DTR–) or Lrrc15DTRGFPwt/ki (DTR+) mice and DT treatment was initiated in both DTR– and DTR+ mice when tumors reached a mean volume of 100-200mm3. scRNAseq of CD24-CD45- stromal cells from a total of 40 tumor-bearing animals across both DTR– and DTR+ genotypes was carried out at four different time points including 10 days post tumor implantation and immediately prior to initiation of DT treatment (IOT) (referred to as day 0) and on days 7, 14, and 21 post IOT.

Project description:CD24 is the one of cell surface protein that anchored via glycosyl phosphatidylinositol that links to cell surface and modulates growth and differentiation signal many of cell types. A small population of cells, namely M-bM-^@M-^XCancer Stem Cells (CSCs)M-bM-^@M-^Y, charges highly aggressive and metastatic character of cancer cells and shows conformational change of M-bM-^@M-^Xepithelial to mesenchymal transition (EMT). To understand the role of CD24 in CSC and EMT, CD24 was knocked down using siRNA in the MCF7 cell line (MCF-7 hCD24 KD) and analyzed transcriptome profiles by mRNA-sequencing. Corresponding author: Chul Geun Kim, Department of Life Science, Hanyang University, Seoul 133-791, Korea (e-mail, cgkim@hanyang.ac.kr). mRNA profiles of MCF-7 hCD24 KD cells [M-bM-^@M-^Xmonolayer (m) cultured MCF7 wild type (WT) and mMCF7 CD24KDM-bM-^@M-^Y and M-bM-^@M-^Xsphere-forming (s) MCF7 WT and sMCF7 CD24KDM-bM-^@M-^Y] were generated by deep sequencing using Illumina GAIIx.

Project description:CD24, or heat stable antigen, is a cell surface sialoglycoprotein expressed on immature cells that disappears after the cells have reached their final differentiation stage. CD24 may be important in human embryonic kidney epithelial cell differentiation. In mice, CD24 expression is up-regulated in the early metanephros and localized to developing epithelial structures but the role and expression of CD24 in the developing human kidney has not been well described. In normal human fetal kidneys from 8 to 38 weeks gestation, CD24 expression was up-regulated and restricted to the early epithelial aggregates of the metanephric blastema and to the committed proliferating tubular epithelia of the S-shape nephron; however individual CD24+ cells were identified in the interstitium of later gestation and postnatal kidneys. In freshly isolated cells, FACS analysis demonstrated distinct CD24+ and CD24+133+ cell populations, constituting up to 16% and 14% respectively of the total cells analyzed. Isolated and expanded CD24+ clones displayed features of an epithelial progenitor cell line. Early fetal urinary tract obstruction resulted in an upregulation of CD24 expression, both in developing epithelial structures of early gestation kidneys and in the cells of the injured tubular epithelium of the later gestation kidneys. These results highlight the cell specific expression of CD24 in the developing human kidney and dysregulation in fetal urinary tract obstruction. We used microarrays to define the differences in global gene expression between obstructed and normal human fetal kidneys. We analyzed RNA extracted from human fetal kidneys between the gestational ages 8 and 18 weeks gestation. This dataset is part of the TransQST collection.

Project description:The adult nucleus pulposus originates from the embryonic notochord, but loss of notochordal cells with skeletal maturity in humans is believed to initiate intervertebral disc degeneration. Thus, defining the phenotype of human embryonic/fetal notochordal cells is essential for understanding their roles and for development of novel therapies. However, a detailed transcriptomic profiling of human notochordal cells has never been achieved. In this study, the notochord-specific marker CD24 was used to specifically label and isolate (using FACS) notochordal cells from human embryonic and fetal spines (7.5-14 weeks post-conception), which were studied by microarray analysis.
