Genome-wide analysis of HOXC4 and HOXC6 regulated genes and binding sites in prostate cancer cells

Project description:Aberrant expression of HOXC6 and HOXC4 is commonly detected in prostate cancer. The high expression of these transcription factors is associated with aggressive prostate cancer and can predict cancer recurrence after treatment. Thus, HOXC4 and HOXC6 are clinically relevant biomarkers of aggressive prostate cancer. However, the molecular mechanisms by which these HOXC genes contribute to prostate cancer is not yet understood. To begin to address the role of HOXC4 and HOXC6 in prostate cancer, we performed RNA-seq analyses before and after siRNA-mediated knockdown of HOXC4 and/or HOXC6 and also performed ChIP-seq to identify genomic binding sites for both of these transcription factors. Our studies demonstrate that HOXC4 and HOXC6 co-localize with HOXB13, FOXA1 and AR, three transcription factors previously shown to contribute to the development of prostate cancer. We suggest that the aberrantly upregulated HOXC4 and HOXC6 proteins may compete with HOXB13 for binding sites, thus altering the prostate transcriptome. This competition model may be applicable to many different human cancers that display increased expression of a HOX transcription factor.

siRNA profiling of human LNCaP cells overexpressing/knockdown of HOXC6

Project description:The transcription factor HOXC6 is upregulated in human prostate cancer. SiRNA knockdown of HOXC6 induces apoptosis in LNCaP cells while upregulation rescued LNCaP cells from siRNA-induced apoptosis. We used microarrays to identify the genes whose expression underly the anti-apoptotic and proliferative effects of HOXC6 in LNCaP cells. Experiment Overall Design: LNCaP cells were transiently transfected with a cocktail of 5 siRNAs to HOXC6 to a final concentration of 100nM, with a HOXC6 gene expression vector, or control siRNA and vector. Cells were collected a 48hours post-transfection

HOXC6 affects the malignant phenotype of esophageal squamous cell carcinoma cells

Project description:HOXC6 is a member of the HOX family, and its aberrant expression has been verified in a variety of cancers, such as prostate, breast,nasopharyngeal carcinoma,gastric, and ovarian cancers.Some studies suggest that HOXC6 might be involved in tumor initiation and progression.However, the role of HOXC6 in esophageal squamous cell carcinoma cells has not been fully investigated.Here we study how HOXC6 affects the malignant phenotype of esophageal squamous cell carcinoma cells

Chromatin Immunoprecipitation microarray data from antiHA IP in stable LNCaP cells expressing either YFP or HOXC6-HA/YFP

Project description:The transcription factor HOXC6 is upregulated in human prostate cancer. SiRNA knockdown of HOXC6 induces apoptosis in LNCaP cells while upregulation rescued LNCaP cells from siRNA-induced apoptosis. We used chromatin immunoprecipitaiton followed by microarray to identify the gene promoters that are bound by HOXC6 in LNCaP cells. Keywords: Stable expression and chromatin immunoprecipitation

Evidence for HOXC6 as a potential molecular marker for non-small cell lung cancer

Project description:HOXC6 is a transcription factor that regulates cell differentiation during embryonic development which is highly expressed in NSCLC, and it may enhance lung cancer progression by regulating the expression of pro-tumorigenic genes involved in proliferation, migration, and invasion. Our study highlighted the oncogenic potential of HOXC6, and suggests that it may be a novel biomarker for the diagnosis and treatment of NSCLC.

HOXC6 drives a therapeutically targetable pancreatic cancer growth and metastasis pathway via stimulating MSK1 kinase and suppressing PPP2R2B protein

Project description:Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers, which lacks effective therapies. Here, we demonstrate that the transcription factor, HOXC6, is overexpressed in most PDACs, and its inhibition blocks PDAC tumor growth and metastasis. HOXC6 transcriptionally activates tumor-promoting kinase MSK1 and suppresses tumor-inhibitory protein PPP2R2B in PDAC. HOXC6-induced PPP2R2B suppression causes mTOR pathway activation, which facilitates PDAC growth. Also, MSK1 upregulation by HOXC6 is necessary for PDAC growth due to its ability to suppress apoptosis via its substrate DDX17. Combinatorial pharmacological inhibition of MSK1 and mTOR potently suppressed PDAC tumor growth and metastasis in PDAC mouse models. PDAC cells with acquired resistance to MSK1/mTOR-inhibitors displayed activated IGF1R signaling and were successfully eradicated by IGF1R inhibitor. Furthermore, MEK inhibitor trametinib enhanced the efficacy of dual MSK1 and mTOR inhibition. Collectively, these results identify therapeutic vulnerabilities of PDAC and an approach to overcome acquired drug resistance to prolong therapeutic benefit.
