Summary
The cell division cycle-associated 7-like protein (CDCA7L) promotes hepatocellular carcinoma (HCC) growth by activating the ERK1/2 pathway. CDCA7L upregulation in HCC suggests it is a potential therapeutic target for liver cancer.
Area of Science:
- Oncology
- Molecular Biology
- Cell Biology
Background:
- The cell division cycle-associated 7-like protein (CDCA7L) is a c-Myc target gene implicated in various tumors.
- Its specific role in hepatocellular carcinoma (HCC) progression is not well understood.
Purpose of the Study:
- To investigate the expression and function of CDCA7L in hepatocellular carcinoma (HCC).
- To elucidate the underlying molecular mechanisms by which CDCA7L influences HCC development.
Main Methods:
- Quantitative analysis of CDCA7L expression in human HCC tissues.
- In vitro studies involving ectopic overexpression and knockdown of CDCA7L in HCC cell lines.
- In vivo tumor xenograft models in nude mice.
- Mechanistic studies focusing on the extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway and cell cycle regulation.
Main Results:
- CDCA7L is significantly upregulated in human HCC tissues.
- Overexpression of CDCA7L enhances HCC cell proliferation and colony formation in vitro.
- CDCA7L knockdown inhibits HCC cell malignant phenotypes.
- In vivo studies demonstrate that CDCA7L overexpression accelerates tumor growth.
- Mechanistic analyses reveal CDCA7L activates the ERK1/2 pathway and regulates the cell cycle.
Conclusions:
- CDCA7L plays a crucial role in promoting hepatocellular carcinoma (HCC) development and progression.
- CDCA7L-mediated activation of the ERK1/2 pathway and cell cycle regulation are key mechanisms.
- CDCA7L represents a potential therapeutic target for HCC treatment.

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...

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.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

7.4K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
