The National Cancer Institute

Area of Science:

  • Oncology
  • Genomics
  • Molecular Biology

Background:

  • The National Cancer Institute's 60 human cancer cell lines (NCI-60) are a vital resource for anticancer drug discovery.
  • Extensive pharmacological and molecular characterization exists for the NCI-60, but systematic mutation analysis of oncogenic genes was lacking.

Purpose of the Study:

  • To perform a systematic mutation analysis of 24 known cancer genes within the NCI-60 cell line panel.
  • To assess homozygous deletions in 4 of these 24 cancer genes.
  • To enhance the utility of the NCI-60 for drug screening and targeted therapy research.

Main Methods:

  • Sequencing analysis of 24 cancer-related genes across the NCI-60 cell lines.
  • Assessment for homozygous deletions in a subset of 4 genes.

Main Results:

  • Identified 137 oncogenic mutations in 14 of the 24 genes analyzed.
  • Mutations were found in APC, BRAF, CDKN2, CTNNB1, HRAS, KRAS, NRAS, SMAD4, PIK3CA, PTEN, RB1, STK11, TP53, and VHL.
  • Every cell line exhibited at least one mutation, with 73% showing multiple mutations in the examined cancer genes.

Conclusions:

  • This comprehensive mutation profile provides critical insights into the genetic landscape of the NCI-60.
  • The identified mutations facilitate a more informed interpretation of drug screening results.
  • This genomic data enhances the NCI-60's value for developing and testing molecularly targeted anticancer agents.

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

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.
