Explore the molecular profile and properties of quiescent (P27+) and mitotic (P27-) glioma cell in diffuse low grade astrocytoma cell lines LGG275

ABSTRACT: Astrocytomas are known to present a cellular heterogeneity consisting of three identified subpopulations: "astrocyte-like", "oligodendrocyte-like" and "NPC-like" cells. It has also been shown that they contain a subpopulations of quiescent, or neural G0 cells, representing more than 90% of the tumor cells. The properties of this cell remain unclear due to the fact that it is difficult to isolate them. We used mVenus/P27 vector expression, constructed by Oki et al (2014), where P27 is fused to mVenus to highlight quiescent cells in LGG275 cell lines, a slow-growing astrocytoma. Then we used this reporter system to sort the mVenus/P27 expressing cells (quiescent) and the negative cells (mitotic) in aims to explore the properties of these two populations and validate the mVenus/P27 tool.

p27 binds to promoters of multiple genes leading to their repression

Project description:The role of the cyclin-cdk inhibitor p27 in tumorigenesis is still a controversial matter. We demonstrate here that p27 negatively regulates transcription of a number of genes (p27-target genes) involved in key cellular functions as RNA processing, translation, respiration and cell proliferation. Crosslinked chromatin from quiescent NIH3T3 cells was sonicated, incubated overnight with the rabbit anti-p27 and IgG antibodies as control

ChIP-seq analysis identifies p27(Kip1)-target genes involved in cell adhesion and cell signalling in mouse embryonic fibroblasts

Project description:The protein p27(Kip1), a member of the Cip-Kip family of cyclin-dependent kinase inhibitors, has been recently identified as a transcriptional regulator. However, the transcriptional programs regulated by this protein, still remain mostly unknown. The aim of this study has been to define the transcriptional programs regulated by p27 by first identifying the p27-binding sites on the whole chromatin of quiescent mouse embryonic fibroblasts by Chromatin Immunoprecipitation Sequencing (ChIP-seq). Results revealed that most of the p27 binding sites were in distal intergenic regions and introns whereas, in contrast, its association with promoter regions was very low. Gene ontology analysis of the protein coding genes revealed a number of relevant transcriptional programs regulated by p27 as cell adhesion, intracellular signalling and neuron differentiation among others. We validated the interaction of p27 with different chromatin regions by ChIP followed by qPCR and demonstrated that the expressions of several genes belonging to these programs are actually regulated by p27.

Cisplatin induces the rearrangement of RBPs on CDKN1B/p27 mRNA

Project description:Cisplatin (CP) is a chemotherapeutic drug that is used to cure different types of cancer. CP induces DNA damage and leads to cell cycle arrest. The cyclin-dependent kinase inhibitor 1B (CDKN1B), also termed p27, plays an important role in the drug response ; and increased levels of p27 correlated with CP resistance. In HEK293 cells, we observed that p27 mRNAs levels increased whereas protein level drastically decreased in cells treated with CP; suggesting post-transcriptional regulatory events. To further understand the underlying mechanisms, we applied a biochemical approach combined with mass-spectrometry to systematically identify the RNA-binding proteins (RBPs) that are bound to the 3’UTR of p27 mRNAs in CP-treated versus non-treated cells in vivo. We found that 24 proteins, most of them known RBPs such HuR, hNRNPD, changed their association with p27 mRNA upon CP treatement. Furthermore, knock-down of a subset of the identified RBPs led to the inhibition of the CP-induced increase of p27 mRNA levels. In conclusion, these results highlight substantial rearrangement between RBPs and p27 mRNA upon CP treatment and corroborate the importance of post-transcriptional control in cellular drug response.

Expression data of NIH3T3 in G0 and G1 phases

Project description:NIH3T3 in the middle of G0 to G1 transion consists of the cells which is still staying G0 phase and the cells which enters G1. Monitoring the expressions of p27 and Cdt1 enables to distinguish these two; p27+/Cdt1+ cells as the cells in G0 phase and p27-Cdt1+ cells as G1 phase We sorted p27+Cdt1+ (G0) NIH3T3 cells and p27-Cdt1+ (G1) NIH3T3 cells in the middle of G0-G1 transition, 5 hours after serum addition following the serum addition using mVenus-p27K- and mCherry-hCdt1(30/120) . We compared the expression profiles of these NIH3T3 cells in G0 and G1 phases and identified the genes upregulated in G0 or G1 phases. The p27+Cdt1+ (G0) NIH3T3 cells and p27-Cdt1+ (G1) NIH3T3 cells were sorted by FACS for RNA extraction and hybridization on Affymetrix microarrays.

The Transcriptomic Landscape of Pediatric Astrocytoma

Project description:Tumors of the central nervous system are the most common solid neoplasia during human childhood, representing one of the leading causes of cancer-related mortality. Tumors that originate from astrocyte cells (astrocytoma) in the brain are the most frequently found. According to their histological and pathological features, these tumors are classified into four categories. However, recently an extra layer of molecular classification of the tumorigenesis-associated genes IDH1/2 and H3F3A has been incorporated into the classification guidelines. While mutations in H3F3A are exclusively found in a subtype of pediatric astrocytoma grade IV, mutations in IDH1/2 are very rare in children younger than 14 years old. The transcriptomic profiles of astrocytoma in adults and children have been extensively studied however focusing on the study of the transcriptomic profile of the different grades of astrocytoma (including the additional layer of molecular classification) in pediatric populations are scarce. Therefore, we have profiled the transcriptomic landscape of the four grades of pediatric astrocytoma by RNA sequencing.

Genome-wide profile of cJun and p27 in breast cancer cells

Project description:We report the genome-wide profile of cJun and p27 in _231 (a line selected for low metastatic ability), _231-1833 (its bone-tropic metastatic derivative line), _231p27CK-DD (a phosphomimetic cell line), and _231-1833shp27 (p27 knockdown cell line). It shows that cJun and p27 broadly binds to genomic DNA and their bindings are regulated by p27 phosphorylation-dependent patterns.
