Insights

Aberrant expression of cancer-testis (C/T) genes in somatic cells can drive cancer development. These genes, normally restricted to male germ cells, offer potential as cancer biomarkers and therapeutic targets.

Area of Science:

  • Epigenetics
  • Cancer Biology
  • Genomics

Context:

  • Epigenetic mechanisms regulate genome organization and gene expression in healthy cells.
  • Cell transformation disrupts normal epigenetic organization, leading to aberrant gene activation or repression.
  • The role of illegitimate tissue-specific gene activation in cancer is not fully understood.

Purpose:

  • To review the oncogenic potential of illegitimate gene expression in somatic cells.
  • To highlight cancer-testis (C/T) genes and their role in epigenome reorganization.
  • To emphasize the value of C/T genes as cancer markers and therapeutic targets.

Summary:

  • This review focuses on cancer-testis (C/T) genes, normally expressed only in male germ cells.
  • Illegitimate expression of C/T genes in somatic cells, particularly those involved in epigenome modification, contributes to oncogenesis.
  • The review explores the implications of C/T gene expression in cancer development and progression.

Impact:

  • Demonstrates the oncogenic potential of aberrantly expressed C/T genes in cancer.
  • Highlights C/T genes as promising biomarkers for cancer detection and diagnosis.
  • Identifies C/T genes and their encoded factors as potential targets for novel cancer therapies.

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

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).
Somatic cells are...
Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
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...
