Insights

Reduced expression of the NPRL2 gene was observed in nearly half of colon cancer patients. Lower NPRL2 levels correlated with more aggressive tumors, suggesting its role in colon cancer progression.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Genetic and epigenetic alterations, including DNA methylation and gene expression changes, are implicated in colon cancer development.
  • Key genes driving colorectal cancer pathogenesis are not fully elucidated.
  • NPRL2, a candidate tumor suppressor gene, is located on human chromosome 3p21.3.

Purpose of the Study:

  • To investigate the role of the NPRL2 gene in colorectal cancer pathogenesis.
  • To evaluate NPRL2 mRNA expression levels in matched normal and tumor colon tissues.

Main Methods:

  • Quantitative reverse transcription polymerase chain reaction (RT-PCR) was employed.
  • Analysis was performed on 55 pairs of matched normal and tumor colon tissue samples.

Main Results:

  • Significantly decreased NPRL2 mRNA expression was detected in 45% of the colorectal cancer patients studied.
  • Lower NPRL2 expression was significantly more frequent in poorly differentiated tumors compared to moderately or highly differentiated tumors.
  • These findings indicate a correlation between reduced NPRL2 expression and tumor aggressiveness.

Conclusions:

  • The study suggests that NPRL2 plays a role in the progression of colon cancer.
  • Decreased NPRL2 expression may serve as a potential biomarker for more aggressive colorectal tumors.

Tumor Progression02:07

Tumor Progression

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...
Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

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.
Such genes that act...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
