Regulation of the master regulator FOXM1 in cancer.

ABSTRACT: FOXM1 (forkhead box protein M1) is a critical proliferation-associated transcription factor that is widely spatiotemporally expressed during the cell cycle. It is closely involved with the processes of cell proliferation, self-renewal, and tumorigenesis. In most human cancers, FOXM1 is overexpressed, and this indicates a poor prognosis for cancer patients. FOXM1 maintains cancer hallmarks by regulating the expression of target genes at the transcriptional level. Due to its potential role as molecular target in cancer therapy, FOXM1 was named the Molecule of the Year in 2010. However, the mechanism of FOXM1 dysregulation remains indistinct. A comprehensive understanding of FOXM1 regulation will provide novel insight for cancer and other diseases in which FOXM1 plays a major role. Here, we summarize the transcriptional regulation, post-transcriptional regulation and post-translational modifications of FOXM1, which will provide extremely important implications for novel strategies targeting FOXM1.

Project description:The FUSCA3 (FUS3) transcription factor is considered to be a master regulator of seed maturation because a wide range of seed maturation events are impaired in its defective mutant. To comprehensively identify genes under the control of FUS3, two types of microarray experiments were performed. First, transgenic plants in which FUS3 expression could be induced by the application of estrogen (ESTR) were used to identify the genes up-regulated in young seedlings of Arabidopsis in response to ectopic expression of FUS3. Second, transcriptomes were compared between fus3 mutant and wild type developing seeds. Combining the results of these experiments identified genes under relatively immediate and robust control of FUS3 during seed development. The analyses expanded the range of types of genes under the control of FUS3. The genes positively controlled by FUS3 are not confined to previously known seed maturation-related genes and include those for production of secondary metabolites such as glucosinolates, phenylpropanoids and falvonoids, and primary metabolism such as photosynthesis and fatty acid biosynthesis. Furthermore, several different patterns were identified in the manner of ectopic activation by FUS3 including the kinetics and abscisic acid (ABA) requirement of downstream genes depending on their natures of developmental regulation, suggesting mechanistic diversity of gene regulation by FUS3. This Series contains two different types of microarray experiments. First, seven-day-old seedlings of the ESTR-inducible FUS3 transgenic plants (ER-FUS3) were cultured for 3, 6, 12, 24, 36 or 48 h in a standard liquid medium or in that containing ESTR, ABA or both. RNA was prepared from each time point sample of each treatment and used to prepare Cy5-labeled cRNA, which was subsequently probed by DNA array with the reference Cy3-labeled cRNA prepared from the time zero untreated seedlings. Two biological replicates per treatment. Second, transcriptomes were compared between developing seeds of the wild-type (Col-0) and the fus3-3 mutant. This experiment contains two seed developmental stages, 8 days after flowering (DAF; bent cotyledon stage) and at 12 DAF (green cotyledon stage). Sample pairs in three biological replicates were analyzed by the two-color method. Dye-swapped hybridizations were performed in every replicate.
