FIT Links c-Myc and P53 Acetylation by Recruiting RBBP7 During Carcinogenesis of Colorectal Cancer

ABSTRACT: Colorectal cancer (CRC) poses one of the most serious threat against human health worldwide, and abnormally expressed c-Myc and p53 are deemed the pivotal driving forces of CRC progression. Here we discovered a lncRNA FIT, which was down-regulated in CRC clinical samples, was transcriptionally suppressed by c-Myc and promoted CRC cells apoptosis by inducing FAS expression. FAS is a p53 target gene, and we found that FIT formed a trimer with RBBP7 and p53 which facilitated p53 acetylation and transcription. Moreover, FIT was capable of retarding CRC growth in mice xenograft model and positively relevant to FAS expression clinically. Thereby our study elucidated the role of lncRNA FIT in human colorectal cancer growth and provides a potential target for anti-CRC drugs.

Fe-FIT-Diff

Project description:au13-06_fit - Fe-FIT-Diff - FIT (FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR) is a regulator of Fe deficiency responses in the root. FIT is a basic helix-loop-helix protein. Here, we investigated the transcriptome changes in response to Fe deficiency (- Fe) versus the control condition (+ Fe) in wild type, the fit-3 loss of function mutant and in FIT overexpression plants.

A recurrently amplified long noncoding RNA in colorectal cancer regulates p53 protein stability through GRWD1/RPL11/MDM2 axis [RNA-seq]

Project description:By integrating genome-wide copy number alteration, RNA-seq and proteomics data from 589 colorectal cancer (CRC) patients, we revealed that chromosome 8q24.21 amplification is negatively correlated with p53 protein stability. Using siRNA and CRISPR activation screening, we pinpointed a novel long noncoding gene (PiHL, P53 inHibiting LncRNA) from 8q24.21 as a p53 negative regulator. PiHL is drastically upregulated in CRC and is an independent predictor of CRC poor prognosis. Further In vitro and In vivo models demonstrate that PiHL is crucial in maintaining cell proliferation and inhibiting cell apoptosis through a p53-depedent manner. Mechanistically, PiHL acts to promote p53 ubiquitination by sequestering RPL11 from MDM2, through enhancing GRWD1 and RPL11 complex formation. We further show that p53 can form a feedback loop with PiHL by directly binding to PiHL promoter and regulating its expression. Our study successfully illustrates how cancer cells hijack the PiHL-p53 axis to promote CRC progression and suggests PiHL as a potential therapeutic target in human CRCs.

lncRNA and mRNA expression profile in colorectal adenoma and cancer

Project description:We evaluated the profile of lncRNA and mRNA expression in 6 colorectal adenoma (CRA), 6 colorectal adenoma (CRC) and 6 matched normal mucosa (NOR) using the Exiqon miRCURY lncRNA and mRNA array,7th generation. We found that global dysregulated lncRNA and mRNAs between colorectal lesions and normal mucosa. Our findings implicates that dysregulation of lncRNA and mRNAs may play important role in the carcinogenesis and present therapeutic targets for CRC.

Prosurvival long noncoding RNA PINCR regulates a subset of p53 targets in colorectal cancer cells by binding to Matrin 3 [Affymetrix Human Gene 2.0 ST]

Project description:Thousands of long noncoding RNAs (lncRNAs) have been discovered, yet the function of the vast majority remains unclear. Here, we show that a p53-regulated lncRNA which we named PINCR (p53-induced noncoding RNA), is induced ~100-fold after DNA damage and exerts a critical prosurvival function in colorectal cancer cells (CRC) in vitro and tumor growth in vivo. Targeted deletion of PINCR in CRC cells significantly impaired G1 arrest and induced hypersensitivity to chemotherapeutic drugs. PINCR regulates the induction of a subset of p53 targets involved in G1 arrest and apoptosis, including BTG2, RRM2B and GPX1. Using a novel RNA pulldown approach that utilized endogenous S1-tagged PINCR, we show that PINCR associates with the promoters of these genes by binding to RNA-binding protein Matrin 3 that, in turn, associates with p53. Our findings uncover a critical prosurvival function of a p53/PINCR/Matrin 3 axis in response to DNA damage in CRC cells.

CRC cells_Aspirin treatment_48 hours_Rep8

Project description:To identify the lncRNA profiles of colorectal carcinoma cells treated with aspirin, we performed microarray analysis using primary cultured cancer cells obtained from 8 clinical CRC tissues. After the CRC cells were treated with aspirin for 48 hours, 28 lncRNAs were statistically up-regulated more than 2-fold. We treated the primary cultured cancer cells obtained from 8 clinical CRC tissues with DMSO (negative control group_Rep8) and aspirin (Experiment group_Rep8).

Long noncoding RNA (lncRNA) expression profiles in colorectal cancer tissues and paired adjacent normal tissues

Project description:Long noncoding RNAs (lncRNAs) play important roles in the tumorigenesis and metastasis of colorectal cancer (CRC). This study used a lncRNA microarray to analyze the aberrant lncRNA expression profiles in CRC tissues compared with paired adjacent normal tissues as well as CRC with regional lymph nodes metastasis compared with CRC without regional lymph nodes metastasis.
