Insights

Tumor cells alter protein production rates for growth advantages. This study reviews how disruptions in DNA, RNA, and protein regulation impact these crucial molecular mechanisms.

Area of Science:

  • Molecular biology
  • Cancer biology
  • Biochemistry

Background:

  • Tumor cells develop growth advantages by varying pro- and anti-tumoral protein synthesis rates.
  • Regulation of protein levels is critical for cellular function and survival.

Purpose of the Study:

  • To provide an overview of molecular mechanisms controlling protein synthesis, maturation, and stability.
  • To identify key events that disrupt these regulatory processes in cancer.

Main Methods:

  • Review of existing literature on gene expression and protein regulation.
  • Analysis of molecular pathways involved in DNA, RNA, and protein control.
  • Identification of common disruptions in cancer cells.

Main Results:

  • Protein production rates are differentially regulated at DNA, RNA, and protein levels.
  • The structural properties of DNA, RNA, and proteins are integral to regulatory mechanisms.
  • Disruptions in synthesis, maturation, and stability control can occur at multiple stages.

Conclusions:

  • Aberrant regulation of protein synthesis contributes to tumor cell proliferation.
  • Understanding these molecular disruptions is key to developing targeted cancer therapies.
  • Interference with DNA, RNA, and protein regulation offers potential therapeutic targets.

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...

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

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.

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.
Such genes that act...
