Insights

Cyclin-dependent kinase 1 (CDK1) and cell division cycle antigen 5 (CDCA5) are upregulated in gastric cancer (GC). Their co-expression promotes GC cell proliferation, migration, and invasion, suggesting potential therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Gastric cancer (GC) remains a significant global health challenge with incompletely understood molecular drivers.
  • Previous research indicated cell division cycle antigen 5 (CDCA5) influences GC cell proliferation, migration, and apoptosis.
  • The precise molecular mechanisms underlying GC development require further elucidation.

Purpose of the Study:

  • To investigate the potential association between cyclin-dependent kinase 1 (CDK1) and CDCA5 in gastric cancer.
  • To determine the expression levels and functional roles of CDK1 and CDCA5 in GC progression.
  • To explore the therapeutic implications of CDK1 and CDCA5 co-expression in gastric tumors.

Main Methods:

  • Bioinformatic analysis using STRING to predict CDK1-CDCA5 association.
  • Expression analysis of CDK1 and CDCA5 in GC tissues via Oncomine and TCGA databases.
  • In vitro functional assays including proliferation, colony formation, scratch, and Transwell migration/invasion assays in MGC-803 GC cells.

Main Results:

  • CDK1 and CDCA5 were found to be upregulated and co-expressed in GC tissues.
  • A positive correlation was observed between CDK1 and CDCA5 expression in MGC-803 cells.
  • Inhibition of either CDK1 or CDCA5 significantly suppressed GC cell proliferation, colony formation, migration, and invasion.

Conclusions:

  • Co-expression of CDK1 and CDCA5 is implicated in promoting the proliferation, migration, and invasion of gastric cancer cells.
  • The findings suggest that the CDK1-CDCA5 axis represents a potential therapeutic target for gastric tumors.
  • Further research into this pathway may offer novel treatment strategies for gastric cancer.

Positive Regulator Molecules02:39

Positive Regulator Molecules

Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.

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...

M-Cdk Drives Transition Into Mitosis02:15

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Anaphase Promoting Complex00:50

Anaphase Promoting Complex

The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
