Reciprocal Regulation of ASPM and FoxM1

Project description:Fork-head box protein M1 (FoxM1) is a transcription factor which plays critical roles in development and progression of multiple cancers, including human hepatocellular carcinoma (HCC). However, the regulatory mechanism of FoxM1 itself remains largely unclear. Here, we discovered a novel role of abnormal spindle-like microcephaly associated (ASPM) in HCC, which binds to FoxM1 protein and enhances its stability by preventing proteasome-mediated degradation. ChIP-sequencing data showed that ASPM and FoxM1 co-occupies on the promoter region of multiple genes to promote their transcriptions, leading to the enhancement of a FoxM1-driven oncogenic progression. Intriguingly, FoxM1 binds to the promoter region of ASPM and transcriptionally activates the ASPM expression. Furthermore, data from clinical samples showed that a higher co-expression of ASPM and FoxM1 significantly correlates with poor prognosis in HCC, indicating that a positive feedforward loop between ASPM and FoxM1 coordinately promotes the aggressive progression in HCC. Collectively, our study reveals that reciprocal regulation of ASPM and FoxM1 amplifies the oncogenic progression and emphasizes an ASPM-FoxM1 feedforward loop could be a potential biomarker and therapeutic target in HCC.

FOXM1-AKT positive regulation loop provides venetoclax resistance in AML

Project description:FOXM1 and AKT are crucial pro-oncogenic regulators of cancer therapy resistance. Due to reciprocal regulatory links they establish a positive feedback autoregulation loop in AML cells. Disruption of this loop via inhibition of either FOXM1 or AKT results in similar gene expression changes, drastic upregulation of HOXA genes and sensitization of AML cells to cytarabine and venetoclax treatment.

FOXM1 dependent regulation of retinal pigment epithelium cell fate

Project description:The integrity of the epithelium is maintained by a complex but regulated interplay of processes that allow seamless orchestration of a proliferative state into a stably differentiated state. In this study, using stem cell derived Retinal Pigment Epithelium (RPE) cells as a model; we have investigated the molecular mechanisms that affect attainment of the epithelial phenotype. We identify a novel role for the proto-oncogene FOXM1 in determining epithelial fate of RPE by directly regulating cell proliferation and by indirectly regulating expression of signalling factors BMP7 and Wnt5B; both of which are intimately required for eventual acquisition of the epithelial phenotype. This study uncovers the role of FOXM1 in a non-oncogenic, native-like setting and shows that human ES derived RPE can serve as a useful model system to address biological questions not restricted to visual function.

Single-cell RNA-seq of ASPM mutant ferret embryonic forebrain

Project description:As described in our paper "Aspm knockout ferret reveals an evolutionary mechanism governing cerebral cortical size" (Johnson et al., Nature 2018), we used the standard Drop-seq method and analysis of Macosko et al. (2015) to capture, sequence, and analyze mRNA from single cells from Aspm wild-type, heterozygous, and knock-out littermate ferrets at embryonic day 35. Bulk reference samples were processed using standard Illumina mRNA-seq library prep and sequencing protocols, and the samples were described previously (Johnson, Wang et al., Nature Neurosci 2015)

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

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.

FOXM1 Cistrome Predicts Breast Cancer Metastatic Outcome Better Than FOXM1 Expression Levels or Tumor Proliferation Index [ChIP-Seq]

Project description:FOXM1 is a key transcription factor regulating cell cycle progression, DNA damage response, and a host of other hallmark cancer features, but the role of the FOXM1 cistrome in driving estrogen receptor-positive (ER+) vs. ER- breast cancer clinical outcomes remains undefined. Chromatin immunoprecipitation sequencing (ChIP-Seq) coupled with RNA sequencing (RNA-Seq) analyses was used to identify FOXM1 target genes in breast cancer cells (MCF-7) where FOXM1 expression was either induced by cell proliferation or repressed by p53 upregulation.
