Insights

Researchers identified key genes involved in skin cancer development. Ten of 14 investigated genes showed altered expression in actinic keratosis and cutaneous squamous cell carcinoma, offering insights into skin carcinogenesis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Dermatology

Background:

  • Carcinogenesis involves genetic mutations and gene dysregulation.
  • The specific genes involved in cutaneous squamous cell carcinoma (SCC) development are not fully understood.

Purpose of the Study:

  • To identify differentially expressed genes in cutaneous SCC and its precursor, actinic keratosis (AK), compared to normal skin.
  • To understand the molecular basis of skin carcinogenesis.

Main Methods:

  • Quantitative real-time reverse transcription PCR was used to analyze mRNA expression.
  • Gene expression was compared between normal skin, AK, and SCC samples (n=20, 10, 10).
  • RNA was extracted from snap-frozen biopsies, and 14 specific genes were investigated.

Main Results:

  • Ten out of 14 genes were significantly dysregulated in AK and/or SCC.
  • Increased expression was observed for CNN2, COX4I1, COX5B, COX7C, CRLF3, CTSC, NDRG1, and LMNA.
  • Down-regulation was noted for RPL15 and LGTN.

Conclusions:

  • Several genes are differentially expressed during skin carcinogenesis.
  • These identified genes may aid in understanding SCC origin and progression.
  • The findings could contribute to developing new diagnostic approaches for skin cancer.

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...

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...
