Cytoplasmic MTDH associates with mRNAs

ABSTRACT: To examine whether MTDH is a novel RNA binding protein and regulates either metabolism or translation of various mRNAs, we performed a RNA-binding protein immunoprecipitation (RIP) with MTDH and IgG antibodies, and the resulting immunoprecipitated RNA was subjected to a microarray to identify transcripts associating with MTDH. In addition we tested the effect of PI3K inhibition using BEZ235 (a dual PI3K/mTOR inhibitor) on the association of MTDH with target mRNAs.

Cytoplasmic MTDH associates with mRNAs

Project description:To examine whether MTDH is a novel RNA binding protein and regulates either metabolism or translation of various mRNAs, we performed a RNA-binding protein immunoprecipitation (RIP) with MTDH and IgG antibodies, and the resulting immunoprecipitated RNA was subjected to a microarray to identify transcripts associating with MTDH. In addition we tested the effect of PI3K inhibition using BEZ235 (a dual PI3K/mTOR inhibitor) on the association of MTDH with target mRNAs. The microarray was performed on three biological triplicates as well as three experimental triplicates of immunoprecipitated MTDH and IgG in Hec50co endometrial cancer cells. Magna RIP (RNA-binding protein immunoprecipitation, Millipore) Kit and microarray were used to immunoprecipitate MTDH associated RNAs and to identify mRNAs that associate with MTDH in the absence or presence of 100nM BEZ235 (LC Labs). Fold changes represent immunoprecipitated MTDH RNA compared to IgG immunoprecipitated RNA. Representative mRNAs associated with MTDH and the effect of BEZ235 on the association of MTDH with mRNAs are shown.

The effect of estradiol and MTDH on gene expression

Project description:During TCGA data analysis, we found that expression of many genes was correlated with the expression of MTDH in estrogen receptor (ESR) positive cancers. The effect of estradiol and MTDH on gene expression in endometrial cancer cells was further analyzed.

Expression data from MTDH knockdown in the Hec50co endometrial cancer cell line

Project description:Understanding the molecular underpinnings of chemoresistance is vital to design therapies to restore chemosensitivity. In particular, metadherin (MTDH) has been demonstrated to have a critical role in chemoresistance. Over-expression of MTDH has recently been implicated in poor clinical outcome in breast cancer, neroblastoma, hepatocellular carcinoma and prostate cancer. In this present study, we focused on the therapeutic benefit of MTDH depletion to restore sensitivity to cell death mediated by a combinatorial therapy of tumor necrosis factor-alpha-related apoptosis-inducing ligand (TRAIL), which promotes death of cancerous cells of the human reproductive tract, and histone deacetylase (HDAC) inhibitors, which have been shown to increase sensitivity of cancer cells to TRAIL-induced apoptosis. Our data indicate that depletion of MTDH in endometrial cancer cells results in sensitization of cells that were previously resistant to cell death mediated by combinatorial treatment with TRAIL and HDAC inhibitor LBH589. MTDH was found to be involved in G2/M checkpoint regulation in response to LBH589 alone or LBH589 in combination with TRAIL, suggesting that MTDH functions at the cell cycle checkpoint to accomplish resistance.Using microarray technology, we identified 57 downstream target genes of MTDH, including Calbindin 1 and Galectin 1, which may contribute to MTDH-mediated resistance to combinatorial TRAIL and HDAC inhibitor targeted therapy. Inhibition of PDK1,AKT phosphorylation and increase Bim expression and XIAP degradation may result in sensitivity to cell death induction in MTDH depleted Hec50co cells by TRAIL and LBH 589 combination treatment. These findings indicate that depletion of MTDH is a potentially novel avenue for effective cancer therapy.

Small Molecule Inhibitors that Disrupt the MTDH-SND1 Complex Suppress Breast Cancer Progression and Metastasis

Project description:Previous studies discovered that MTDH frequently amplifies and overexpresses in breast cancer in human patients and is strongly associated with higher metastasis and treatment failure and thereby leads to poor prognosis. In mouse mammary tumor models, knockout of Mtdh substantially reduces tumor incidence and suppresess metastasis. Furthermore, Mtdh interact with Snd1 and the interaction appears essential for its tumor promoting function. To develop novel therapeutics targeting Mtdh function, small molecular compound to disrupt the Mtdh-Snd1 interaction was identified by high throughput screen. To further elucidate the mechanism of MTDH targeting caused anti-tumor activity and to confirm the action mode of the small molecular compound C26A6 as a Mtdh-Snd1 disruptor, transcriptome changes in mouse mammary tumors following treatments of C26A6 and acute induction of Mtdh knockout by Tamoxifen treatment were investigated using next generation sequencing.

Snd1-Mtdh interaction regulates cell survival under camptothecin-induced replication stress

Project description:PyMT tumor cells with indicated status of Mtdh and Snd1 were treated with camptothecin (CPT) and the transcirptome profiles were determined and compared two sets of experiments: (1) vector control vs Snd1-KD under CPT treament (2) PyMT/Mtdh-KO cells reconstituted with either WT or Snd1-binding deficient mutant Mtdh (W391D) under CPT treatment
