Global binding profiles of MYBL2 and FOXM1 in lung adenocarcinoma reveal that MYBL2 regulates FOXM1 to control cell-cycle genes including CENPA [ChIP-seq]

Project description:MYBL2 is a transcription factor that has either pro-survival or anti-survival functions in a cell-type specific manner. Overexpression of MYBL2 is associated with worse survival of lung adenocarcinoma, but the mechanism by which it regulates transcription has not yet been elucidated. In this study, we found that MYBL2 mainly binds to the promoters of highly expressed genes in lung adenocarcinoma cells using ChIP-seq. Using knock-down and RNA-seq approach, we identified over a thousand of genes deregulated by MYBL2. By integrating ChIP-seq and RNA-seq data, we identified target genes of MYBL2. We revealed that FOXM1 is regulated by MYBL2 in lung adenocarcinoma cells, and FOXM1 binding sites are largely shared with MYBL2 binding sites. We treated lung adenocarcinoma cells with FDI-6, a known FOXM1 inhibitor and investigated the effect of FDI-6 in transcriptional regulation of MYBL2 and FOXM1. We found that CENPA is one of the key genes regulated by MYBL2 and FOXM1, and that it can be inhibited by FDI-6. Our signaling pathway analysis results revealed that MYBL2 and FOXM1 activate cell-cycle genes, suggesting that MYBL2 and FOXM1 act as oncogenic transcription factors in lung adenocarcinoma cells and FDI-6 could be a potential treatment of the disease.

MYBL2 promotes proliferation and metastasis of bladder cancer through transactivation of CDCA3

Project description:The transcription factor MYB proto-oncogene like 2 (MYBL2) plays a critical role in the regulation of gene expression and tumorigenesis. However, the biological function of MYBL2 in bladder cancer (BLCA) remains to be elucidated. Here, we first revealed that MYBL2 was elevated in BLCA tissues and was significantly correlated with clinicopathological parameters and cancer-specific survival of BLCA patients. Phenotypic assays showed that MYBL2 deficiency suppressed the proliferation and migration of BLCA cells in vitro and in vivo, whereas overexpression of MYBL2 contributed to the opposite phenotype. Mechanistically, MYBL2 could bind to the promoter of its downstream target gene cell division cycle-associated protein 3 (CDCA3) and transactivate it, which in turn promoted the malignant phenotype of BLCA cells. Further investigations revealed that MYBL2 interacted with forkhead box M1 (FOXM1) to co-regulate the transcription of CDCA3. In addition, MYBL2 and CDCA3 may activate the Wnt/β-catenin signaling by inhibiting the suppressor dickkopf-1 (DKK1), thereby regulating the malignant phenotype of BLCA cells. In conclusion, the current study has identified MYBL2 as an oncogene in BLCA. MYBL2 can accelerate the proliferation and metastasis of BLCA through the transactivation of CDCA3.

Functional Taxonomy of CENPA-Bound Genes in Prostate Cancer

Project description:Overexpression of centromeric proteins has been identified in a number of human malignancies, though their functional and mechanistic contributions to disease progression have not been characterized. CENPA, the centromeric histone H3 variant, is the epigenetic mark that determines centromere identity. Here, we demonstrate that CENPA is highly overexpressed in prostate cancer in both tissue and cell lines, and the level of CENPA expression correlates with the stage of disease. Gain-of- and loss-of-function experimentation confirms that CENPA promotes prostate cancer cell line growth. Integrated sequencing studies further reveal a previously unidentified function of CENPA as a transcriptional regulator that modulates expression of critical proliferation, cell-cycle, and centromere/kinetochore genes. Our findings, therefore, suggest a previously undescribed biological function for CENPA, a protein normally thought to be solely and importantly involved in centromere identity.

Contribution of CENP-F to FOXM1-mediated discordant centromere and kinetochore transcriptional regulation. [RNAseq_KD]

Project description:Proper chromosome segregation is required to ensure genomic and chromosomal stability. The centromere is a unique chromatin domain present throughout the cell cycle on each chromosome defined by the CENP-A nucleosome. Centromeres (CEN) are responsible for recruiting the kinetochore (KT) during mitosis, ultimately regulating spindle attachment and mitotic checkpoint function. Upregulation of many genes that encode CEN/KT proteins is commonly observed in cancer. Here, we show although FOXM1 occupies the promoters of many CEN/KT genes with MYBL2, occupancy is insufficient alone to drive the FOXM1 correlated transcriptional program. We show that CENP-F, a component of the outer kinetochore, functions with FOXM1 to coregulate G2/M transcription and proper chromosome segregation. Loss of CENP-F results in alteration of chromatin accessibility at G2/M genes, including CENP-A, and leads to reduced FOXM1-MBB complex formation. The FOXM1-CENP-F transcriptional coordination is a cancer-specific function. We observed that a few CEN/KT genes escape FOXM1 regulation such as CENP-C which when upregulated with CENP-A, leads to increased chromosome misegregation and cell death. Together, we show that the FOXM1 and CENP-F coordinately regulate G2/M gene expression, and this coordination is specific to a subset of genes to allow for proliferation and maintenance of chromosome stability for cancer cell survival.
