Differences in gene expression between multicellular spheres and adherent cell of tongue cancer cell lines CAL27 and HSC3
Ontology highlight
ABSTRACT: To investigate the differences in gene expression between multicellular spheres and adherent cell of tongue cancer cell, We compared the difference in gene expression between CAL27 and HSC3 cultured in suspension culture and adherent culture.
Project description:Transcriptional profile of LNCaP spheres in SCM-1% KO (stem-like cells) vs adherent cultures in RPMI-1640-10% FBS (differentiated-like cells)
Project description:Transcriptional profile of PCSC spheres in SCM-1% KO (stem-like cells) vs adherent cultures in PCSC-Celprogen medium (differentiated-like cells) Two-condition experiment: Sphere vs. Parental/adherent cells. Biological replicates: 2 sphere replicates , 2 adherent replicates.

Biological replicates: 2 sphere replicates , 2 adherent replicates. Early passaged tumor cells were expanded in adherent conditions and then plated in sphere forming conditions (SCM-1KO% medium at low density) to isolate sphere growing cells.

Project description:We have recently demonstrated that human paediatric mesenchymal stem cells can be reprogrammed toward a Ewing’s sarcoma family tumor (ESFT) cancer stem cell (CSC) phenotype by mechanisms that implicate microRNAs (miRNAs). Here, we show that the miRNA profile of ESFT CSC is shared by embryonic stem cells and CSC from divergent tumor types. We also provide evidence that the miRNA profile of ESFT CSC is the result of reversible disruption of TARBP2-dependent miRNA maturation. Restoration of TARBP2 activity and systemic delivery of synthetic forms of either of two of its targets, miRNA-143 or miRNA-145, inhibited ESFT CSC clonogenicity and tumor growth in vivo. Our observations suggest that CSC self-renewal and tumor initiation may depend on deregulation of TARBP2-dependent miRNA expression. 2 Ewing sarcoma primary samples: comparison between spheres and derived adherent cells.
Project description:We cultured adherent primary cell lines from NB tumor samples. Adherent primary cell lines from NB tumor samples have a subpopulation of neural crest progenitors that grow as spheres when cultured in low-binding conditions.
Project description:Rhabomyosarcoma cells can be cultured in stem cell medium over several passages and form spheres being enriched in putative cancer stem cell markers and expressing high levels of stem cell genes. In this dataset, we include RNA samples from 2 rhabdomyosarcoma cell lines and 3 different sphere passages of each cell line. 16 samples were analyzed and all sphere passages were compared to the expression level of their corresponding adherent cell line. We wanted to see an up- or downregulation of genes in the spheres to identify new potential cancer stem cell marker.
Project description:Metastatic prostate cancer is a leading cause of cancer-related death in men. Cancer stem cells (CSCs) are involved in tumor progression and metastasis, including in prostate cancer. There is an obvious and urgent need for effective cancer stem cells specific therapies in metastatic prostate cancer. MicroRNAs (miRNAs) are an important class of pervasive genes that are involved in a variety of biological functions, especially in cancer. The goal of this study was to identify miRNAs involved in prostate cancer metastasis and cancer stem cells. Several published reports have demonstrated that non-adherent spheres culture is increasingly used as an effective method to enrich and identify stem cells or putative CSCs.In our previous study, we enriched prostate cancer stem cells from PC-3 sphere cells in serum-free suspension culture and characterized their CSCs properties.Thus, we used spheres as a prostate cancer stem cells model to elucidate its metastatic mechanisms. We examined the miRNA expression profiles of PC-3 sphere cells of prostate cancer compared with PC-3 adherent cells by miRNA microarray.
