Insights

Steroid 17α-hydroxylase/17,20-lyase (CYP17) inhibition treats hormone-dependent cancers. This review analyzes CYP17 genetics, structure, specificity, and inhibitors for cancer therapy.

Area of Science:

  • Biochemistry
  • Endocrinology
  • Oncology

Background:

  • Prostate and breast cancers are often hormone-dependent.
  • Inhibiting steroid 17α-hydroxylase/17,20-lyase (CYP17) is a key treatment for androgen-dependent prostate cancer.
  • CYP17 is essential for steroid hormone biosynthesis, directing pathways towards corticosteroids or sex hormones.

Purpose of the Study:

  • To review current knowledge on CYP17.
  • To analyze the genetics, molecular structure, substrate specificity, and inhibitors of CYP17.

Main Methods:

  • Literature review of scientific articles on CYP17.
  • Analysis of existing data on CYP17 genetics and structure.
  • Discussion of substrate specificity and known inhibitors.

Main Results:

  • CYP17 possesses dual enzymatic activities: 17alpha-hydroxylase and 17,20-lyase.
  • The enzyme's activity dictates the production of either corticosteroids or sex hormones.
  • Information on CYP17 genetics, structure, substrate interactions, and inhibition is synthesized.

Conclusions:

  • Understanding CYP17's role and characteristics is vital for developing targeted cancer therapies.
  • Further research into CYP17 inhibitors could lead to improved treatments for hormone-dependent cancers.

Cancer-Critical Genes I: Proto-oncogenes

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.

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.

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...
