Summary
Depleting Jumonji C domain-containing (JMJD) 5 significantly inhibits colon cancer cell proliferation, migration, and invasion. JMJD5 is upregulated in colon cancer tissues and linked to lower patient survival rates, suggesting it may be an oncogene.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Colon cancer (CC) remains a significant global health challenge.
- Understanding the molecular mechanisms driving CC progression is crucial for developing effective therapies.
Purpose of the Study:
- To investigate the role of Jumonji C domain-containing (JMJD) 5 in the development and progression of colon cancer.
- To evaluate the impact of JMJD5 depletion on colon cancer cell behavior in vitro and its expression in patient tissues.
Main Methods:
- JMJD5 was depleted in Caco-2 human colon cancer cells using lentiviral short-hairpin RNA (shRNA).
- Quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting assessed JMJD5 mRNA and protein levels.
- Cell proliferation, migration, and invasion were evaluated using MTT assays, soft agar colony formation assays, and Transwell assays, respectively.
- Immunohistochemical (IHC) staining analyzed JMJD5 expression in CC patient tissues and adjacent normal tissues.
Main Results:
- JMJD5 depletion significantly reduced JMJD5 mRNA and protein levels in Caco-2 cells.
- Inhibition of JMJD5 significantly suppressed colon cancer cell proliferation, migration, and invasion.
- JMJD5 was found to be significantly upregulated in colon cancer tissues compared to normal adjacent tissues.
- High JMJD5 expression in patients correlated with a significantly lower survival rate.
Conclusions:
- JMJD5 depletion effectively inhibits colon cancer cell proliferation, migration, and invasion.
- JMJD5 is upregulated in colon cancer and associated with poor patient prognosis.
- These findings suggest that JMJD5 acts as a potential oncogene in colon cancer and may represent a therapeutic target.

2.1K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

12.0K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
