TranscriptomicsA large intergenic non-coding RNA induced by p53 mediates global gene repression in the p53 transcriptional response
Recently, more than a thousand large intergenic non-coding RNAs (lincRNAs) have been reported. These RNAs are evolutionarily conserved in mammalian genomes and thus presumably function in diverse biological processes. Here, we report the identification of lincRNAs that are regulated by p53. One of ...

TranscriptomicsStage-specific sensitivity to p53 restoration in lung cancer: tumor data
Tumorigenesis is a multistep process that results from the sequential accumulation of mutations in key oncogene and tumor-suppressor pathways. The quest to personalize cancer medicine based on targeting these underlying genetic abnormalities presupposes that sustained inactivation of tumor suppresso...

GenomicsTo examine the role of p300 in the SMARCA4–p53 regulatory axis, we performed ChIP-seq to assess p300, p53, H3K27ac, HDAC1, HDAC2 occupancy in BIN-67 cells
ChIP-seq was performed in BIN-67, BIN-67 p53ko, BIN-67 with SMARCA4 restoration and BIN-67 p53ko cells with SMARCA4 restoration to assess the impact of SMARCA4 and p53 on the pull downs of p300, H3K27ac, p53, HDAC1 and HDAC2.

TranscriptomicsPINT lincRNA connects the p53 pathway with epigenetic silencing by the Polycomb Repressive Complex 2 (MEF cells)
It has been recently shown that the transcription factor p53 induces the expression of multiple lincRNAs. However, relatively little is known about the role that lincRNAs play in this pathway. Here we characterize a lincRNA named PINT (p53 Induced Noncoding Transcript). We show that PINT is a ubiqui...

TranscriptomicsRestoration of miR-214 expression reduces cell growth of myeloma cells through a positive regulation of P53 and inhibition of DNA replication
MicroRNAs have been demonstrated to be deregulated in multiple myeloma (MM). We have previously reported the downregulation of miR-214 in MM compared to normal plasma cells. In the present study, we have explored the functional role of miR-214 in myeloma pathogenesis. Ectopic expression of miR-214 r...

TranscriptomicsExamining the effect of SMARCA4–p53 regulatory axis on SCCOHT cells transcription
To examine the role SMARCA4-p53 regulatory axis in SCCOHT cells we performed RNA-seq in BIN-67 cells with SMARCA4 restoration, p53ko alone or combined with SMARCA4 and idasanutlin treatment (0.5μM, 24h) which increase the stability of p53 and its protein levels in SCCOHT.

TranscriptomicsTargeting MDM4/MDM2 binding interface for reactivation of p53 in cancer therapy
The aim of this experiment has been to investigate the transcriptional profile of HCT116 cells treated with Peptide-3 (Pep3) compared to untreated (NT), treated with solvent (DMSO) or with a mutated peptide (Pep3M) cells. Peptide-3 is a dodecapeptide able to interact with MDM2 at the levels of the i...
