Spontaneous cell competition in U2OS human osteosarcoma cells.

ABSTRACT: The study compares the transcriptional profiles of U2OS human osteosarcoma cells and those of two single-cell derived sub-lines carrying a stably integrated H2BmCherry (U2OS-R1) or H2B-YFP (U2OS-YFP) expression cassette. U2OS-R1 and U2OS-YFP cell spontaneously undergo apoptosis upon co-culture with the parental (Wt) U2OS cell population. Furthermore, YFP cells also undergo apoptosis upon co-culture with R1 cells. This behavior is similar to the \cell competition\ phenomenon described in the Drosophila imaginal disc and the mouse epiblast (for review, see , where fast-growing \fit\ cells induce apoptosis in slow-growing, less \fit\ neighbors. The mRNA expression profiles of Wt, R1 and YFP cells cultured alone or in pairwise combinations for 48h were analyzed after cell sorting by RNA microarray hybridization using Affymetrix Human Gene ST 1.0 chips.

Gene expression profile of cells with unfit Wnt morphogen gradient during cell competition

Project description:Morphogen signalling forms an activity gradient and instructs cell identities in a signalling strength-dependent manner to pattern developing tissues. However, developing tissues also undergo dynamic morphogenesis, which may produce cells with unfit morphogen signalling and consequent noisy morphogen gradient. Here we show that a cell competition-related system corrects such noisy morphogen gradients. Zebrafish imaging analyses of the Wnt/β-catenin signalling gradient, which acts as a morphogen to establish embryonic anterior-posterior patterning, revealed that unfit cells with abnormal Wnt/β-catenin activity spontaneously appear and produce noise in the gradient. Communication between unfit and neighbouring fit cells via cadherin proteins stimulates apoptosis of the unfit cells by activating Smad signalling and reactive oxygen species production. This unfit cell elimination is required for proper Wnt/β-catenin gradient formation and consequent anterior-posterior patterning. Because this gradient controls patterning not only in the embryo but also in adult tissues, this system may support tissue robustness and disease prevention.

Transcription profiling by array of human osteosarcoma U2OS cell line conditionally expressing HA-tagged PRDM5

Project description:PRDM5 is a recently identified member of the PRDM family of proteins, which functions as a transcriptional repressor by recruiting histone methyltransferase G9A to DNA, and behaves as a putative tumor suppressor in different types of cancer. We investigated PRDM5 function by identifying its target genes in U2OS cells at different time points after expression of PRDM5 protein. Experiment Overall Design: We analyzed gene expression profiles of a U2OS cell line conditionally expressing HA-tagged PRDM5 (U2OS-PRDM5), where PRDM5 is under the transcriptional control of a doxycycline-inducible promoter. Expression of PRDM5 protein is detectable after 8 hours of induction with 2ug/ml doxycycline, and increases steadily up to 48 hours, after which cells begin to undergo apoptosis. U2OS cells containing the empty cloning vector (U2OS-pSG213) were used as controls for each condition.

Identification of GmMYB176 interactome in soybean by Co-immunoprecipitation and LC-MS/MS

Project description:GmMYB176 is an R1 MYB transcription factor that regulates multiple genes in the isoflavonoid biosynthetic pathway thereby affecting isoflavonoid level in soybean roots. While GmMYB176 is important for isoflavonoid synthesis, it is not sufficient for the function and requires additional cofactor (s). The aim of this study was to identify GmMYB176 interactome for the regulation of isoflavonoid biosynthesis in soybean. GmMYB176 interactome was identified by Co-Immunoprecipitation using two YFP-tagged proteins baits, N’-GmMYB176-YFP-C’ and N’-YFP-GmMYB176-C’. GmMYB176 interacting proteins were identified by LC-MS/MS.

gene profiling changes induced by regulation of Brachyury expression

Project description:Chordoma is a rare malignant bone tumor on axial skeleton, locally invasive and has a high rate of recurrence. Despite extensive studies, the mechanisms of tumor recurrence after surgical intervention, as well as resistance to radiation and chemotherapy, remain elusive. In this study, cell lines PCH1 and PCH2 were established and characterized by chordoma specific markers. We found that the embryonic transcription factor brachyury inhibits taxol induced apoptosis in different cells, including PCH1 and U2OS cells. Brachyury regulated genes were identified in PCH1 and U2OS using microarray. Brachyury is an embryonic transcription factor involved in embryo development. We emplored the downstream genes related to apoptosis of Brachyury by microarray in different cell lines: U2OS, PCH1 and H460.

Project description:Chromatin immuno-precipitation using anti-Flag (Sigma) or control IgG (Millipore) antibodies in a U2OS stable cell line. ZMYM2 has the synonym ZNF198. Note: paired-end sequencing libraires were created in this experiment but only the forward (R1) reads are available in this submission. The 'LIBRARY_LAYOUT' attribute is therefore set to be 'SINGLE' ather than 'PAIRED'.
