Identification of mRNAs modulated by the HOXB7-MEK signaling cascade

ABSTRACT: Transcripts upregulated or downregulated by HOXB7-MEK signaling were identified for use on the microarray using the Affymetrix GeneChip WT PLUS Reagent Kit in comparison with HOXB7-knockdown S2-013 cells that were transfected with rescue-HOXB7 plasmid and treated with MEK inhibitor, and HOXB7-knockdown S2-013 cells that were transfected with rescue-HOXB7 plasmid but not treated with MEK inhibitor.

Identification of several potential chromatin binding sites of HOXB7 and its downstream target genes in breast cancer

Project description:We report the chromatin binding sites of HOXB7 transcription factor in BT-474 breast cancer cell line using ChIP-sequencing. We validated the chromatin binding sites in BT-474, MDA-MB-361, MCF7 and T-47D breast cancer cell lines using ChIP-qPCR. The ChIP experiments have been performed using HOXB7 antibody and IgG non-specific antibody as a negative control. The direct downstream target genes of HOXB7 were identified by analyzing the expression of genes located nearby HOXB7 binding sites in HOXB7 knockdown versus control cells using qRT-PCR. Examination of chromatin binding sites of HOXB7 in BT-474 breast cancer cell line using ChIP-seq. Four parallel IgG samples were sequenced, merged together and used as a control data set. Two parallel HOXB7 ChIP samples were sequenced and merged for each replicate, AF1 and AF2. Both HOXB7 ChIP replicates (AF1 and AF2) contained approximately the same amount of reads as the merged IgG control data set.

human HCC cell MHCCLM3: HOXB7-siRNA transfected vs. control

Project description:We found that HOXB7 promotes HCC cell proliferation, migration, and invasion. To further explore the mechanism, we performed a cDNA microarray assay to compare the differential gene expression profiles of HOXB7 depletion (HOXB7-siRNA-treated) and negative control siRNA-treated in MHCCLM3 cells.

Identification of mRNAs modulated by knockdown of CD24

Project description:We endeavored to identify factors and pathways regulated by CD24 and to obtain leads regarding the mechanism by which CD24 inhibited the invasiveness and metastasis of pancreatic cancer cells by performing cDNA microarray analysis on S2-013 CD24 RNAi clones and control clones. The group of genes showing increased expression was mainly comprised of genes for molecules with functions related to RNA metabolism, transcription factors, proteases, and molecules involved in embryonic development and cell growth. The set of genes downregulated by knockdown of CD24 included the target mRNAs of a phosphorylation-dependent endoribonuclease G3BP that interacted with CD24. The target mRNAs of G3BP were identified in GSE17056. These results suggested that CD24 inhibited the RNase activity of G3BP, and that a function of CD24 was to inhibit the degradation of specific mRNAs. Transcripts upregulated or downregulated by knockdown of CD24 were identified through expression profiling of a total of 12,135 genes in S2-013 CD24 RNAi clones compared to control clones. Before labeling with Cy5 or Cy3, total RNA from two S2-013 CD24 RNAi clones were mixed and total RNA from two control clones were mixed. The supplementary files 'GSE17055_higher_siCD24.txt' and 'GSE17055_higher_control.txt' list the differentially expressed genes.

RNA immunoprecipitation (RIP) of KHSRP from pancreatic cancer cell extracts cultured on fibronectin

Project description:KHSRP-bound transcripts were identified by RNA immunoprecipitation and sequencing (RIP-Seq) and bioinformatics analysis. A pancreatic cancer cell line S2-013 was cultured on fibronectin. We performed RIP of KHSRP using anti-KHSRP antibody from the fibronectin-stimulated S2-013 extracts, and identified the associated RNAs using a next generation sequencer.

HOXB7 is an ERÎ± cofactor in the activation of HER2 and multiple ER target genes leading to endocrine resistance

Project description:Why breast cancers become resistant to tamoxifen despite continued expression of the estrogen receptor alpha (ERÎ±) and what factors are responsible for high HER2 expression in these tumors remains an enigma. HOXB7 ChIP analysis followed by validation showed that HOXB7 physically interacts with ERÎ±, and that the HOXB7-ERÎ± complex enhances transcription of many ERÎ± target genes including HER2. Investigating strategies for controlling HOXB7, our studies revealed that MYC, stabilized via phosphorylation mediated by EGFR-HER2 signaling, inhibits transcription of miRNA-196a, a HOXB7 repressor. This leads to increased expression of HOXB7, ER-target genes and HER2. Repressing MYC using small molecule inhibitors reverses these events, and causes regression of breast cancer xenografts. The MYC-HOXB7-HER2 signaling pathway is eminently targetable in endocrine-resistant breast cancer. MCF7 cell lines stably transduced with either vector control of HOXB7. Array ran in duplicates.

HOXB7 mRNA is overexpressed in pancreatic ductal adenocarcinomas and its knockdown induces cell cycle arrest and apoptosis.

Project description:In order to determine the role of HOXB7 gene in cell lines derived from pancreatic ductal adenocarcinoma (MIA PaCa-2 e Capan-1), we performed its silencing utilizing the technique of RNA interference (RNAi). Total RNA derived from the inhibition as well as from parental cells was quantified in Bioanalyzer (Agilent,Santa Clara, CA, USA) and employed in the Agilent platform (4x44K). Proceeded with the guidelines of the One Color Microarray-Based Gene Expression Protocol (Agilent) and with the use of the Agilent Low Input Quick Amp Labeling Kit. HOXB7 knockdown elicited the modulation of several biological processes, especially in the MIA Paca-2 cell line, such as proteasomal ubiquitin-dependent catabolic process, synthesis of amines and cell cycle. Moreover, it showed induction of apoptosis and reduction in cell proliferation by flow cytometry and MTT assay, respectively. In this context, HOXB7 represents another component associated with the extensive network of molecules involved in the tumorigenesis of pancreatic cancer and could be a promising target for future biologic therapies. The procedure was performed in duplicate for both cell lines, which were sorted into treated and untreated with RNAi.
