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: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.

Project description:Durable remissions following anti-B cell maturation antigen (BCMA)-specific chimeric antigen receptor (CAR) T-cell treatment of multiple myeloma (MM) are rare. Relapses occur when a small subset of MM tumor-initiating cells (TICs) survive treatment. MM cells expressing CD24 exhibit features of TICs. We developed CD24-CAR-T cells and tested their ability to eliminate MM TICs in vitro and in vivo.

Project description:8 pairs of myeloma cell lines were sorted by MACS CD138-microbead, and the each cell lines were divided into two fraction CD138+ and CD138-. We used microarrays to detail the global programme of gene expression in these 8 pairs of CD138+/- myeloma cell lines CD138- fraction in myeloma are thought to be myeloma stem cells fraction, and we compared the gene expression profile between CD138- and CD138+ fraction.

Project description:Type II germ cell tumors (GCTs) are with more than 90% the most common neoplasia in young men of age 14 - 45 years. It is generally accepted that GCTs arise from a common precursor lesion, called germ cell neoplasia in situ (GCNIS), eventually developing into seminomas or non-seminomas. The non-seminomatous stem-cell like embryonal carcinomas (EC) can further differentiate into teratomas (TE), yolk sac tumors (YST), or choriocarcinomas (CC). Orchiectomy followed by chemo- or radiotherapy is a widely used procedure in the treatment of type II GCTs, leading to high cure rates of up to 90%. Nevertheless, about 10 - 15% of patients with progressive disease relapse as a result of drug resistance and are condemned for a poor prognosis and a short survival of only a few months. Cluster of differentiation 24 (CD24) is a small, mucin-like glycosylphosphatidylinositol (GPI) anchored membrane molecule that functions both, in signal transduction and as an adhesion molecule. This glycoprotein is mainly expressed on the surface of hematopoietic, neural, muscular, and epithelial cells. Moreover, CD24 has been implicated in tumor metastasis, as fucosylated CD24 interacts with P- and E-selectin, allowing invasion of tumor cells to distal sites. High expression or amplifications of CD24 has been described in a variety of solid malignancies, such as non-small cell lung carcinoma, gliomas, breast cancer, retinoblastoma, hepatocellular carcinoma, renal cell carcinoma, cervical carcinoma, prostate cancer, urothelial carcinoma, pineal parenchymal tumors, and ovarian cancer. In this study, we investigated the putative function of CD24 and its interaction partners in (cisplatin-resistant) GCT cell lines by generating CD24-deficient EC cells by CRISPR/Cas9-mediated gene editing. Changes in the proteome between CD24-deficient cells and parental cells were measured by liquid-chromatography coupled with mass spectrometry (LS-MS).

Project description:We found that a small molecule inhibitor of PRMT4 inhibited cell growth of a subset of multiple myeloma cell lines. To identify biomarkers that predict the sensitivity of myeloma cells to PRMT4 inhibition, we performed transcriptomic analysis of multiple myeloma cell lines.

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.
