Insights

This study reveals a new pathway involving Zinc finger protein 146 (ZNF146), Transcription factor Dp-1 (TFDP1), and DEP domain-containing protein 1B (DEPDC1B) that regulates the cell cycle in ovarian cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Ovarian cancer (OC) is a lethal gynecological malignancy.
  • Aberrant cell cycle progression is a hallmark of tumorigenesis.
  • The role of Transcription factor Dp-1 (TFDP1) in OC requires further elucidation.

Purpose of the Study:

  • To investigate the regulatory role and mechanism of TFDP1 in ovarian cancer.
  • To identify novel regulators of the cell cycle in OC.

Main Methods:

  • Analysis of TFDP1 expression in OC tissues and cells.
  • Gene silencing experiments (ZNF146 knockdown, TFDP1 silencing).
  • Assessment of cell cycle progression and tumor growth in vivo.

Main Results:

  • TFDP1 expression is elevated in OC and promotes cell proliferation and cell cycle entry.
  • ZNF146 knockdown inhibits OC cell growth by suppressing TFDP1 transcription.
  • TFDP1 activates DEP domain-containing protein 1B (DEPDC1B) expression, promoting G2/M phase transition and tumor progression.

Conclusions:

  • The ZNF146/TFDP1/DEPDC1B axis is a critical regulator of the cell cycle in ovarian cancer.
  • Targeting this axis may offer novel therapeutic strategies for OC.

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Molecular Factors Affecting Cell Division01:27

Molecular Factors Affecting Cell Division

Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...

The Cell Cycle Control System01:28

The Cell Cycle Control System

The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.
Cyclins and cyclin-dependent kinases (Cdks) are the primary cell cycle regulators and...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
