Insights

Forkhead box protein M1 (FOXM1) transcriptionally activates the UBE2C gene, which is overexpressed in many cancers. This FOXM1-UBE2C pathway deregulation is a common event in human neoplasias.

Area of Science:

  • Oncology
  • Molecular Biology
  • Gene Regulation

Background:

  • FOXM1 is a key transcription factor regulating cell cycle and proliferation in tumor development.
  • UBE2C, involved in cell cycle progression, is overexpressed in various solid tumors.
  • Both FOXM1 and UBE2C are frequently overexpressed in human cancers.

Purpose of the Study:

  • To determine if UBE2C is a transcriptional target of FOXM1.
  • To investigate the FOXM1-UBE2C regulatory relationship in esophageal squamous cell carcinoma (ESCC) and other cancers.

Main Methods:

  • Correlation analysis of FOXM1 and UBE2C expression in normal and tumor tissues.
  • Chromatin immunoprecipitation (ChIP) assay to assess FOXM1 binding to the UBE2C promoter.
  • Analysis of gene expression data from multiple cancer types.

Main Results:

  • A positive correlation between FOXM1 and UBE2C expression was observed in normal tissues and 25 tumor types, including ESCC.
  • FOXM1 was found to bind to the UBE2C promoter region in an ESCC cell line.
  • FOXM1 transcriptionally activates UBE2C, leading to its upregulation.

Conclusions:

  • FOXM1 directly regulates UBE2C expression at the transcriptional level in ESCC.
  • The observed deregulation of FOXM1 and UBE2C is a widespread phenomenon in human neoplasias.
  • This regulatory axis represents a potential target for cancer therapy.

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Cooperative Binding of Transcription Regulators02:13

Cooperative Binding of Transcription Regulators

Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

Transcriptional Regulation: Riboswitches01:23

Transcriptional Regulation: Riboswitches

Riboswitches are RNA elements that regulate gene expression by altering their secondary structures in response to specific effector molecules. These elements, located in the leader regions of certain mRNAs, act as transcriptional regulators by toggling between alternative conformations to control downstream gene expression. Riboswitch-mediated regulation is a precise mechanism for modulating biosynthetic pathways, as exemplified by the riboflavin biosynthesis pathway in Bacillus...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
