Abstract

Insights

Deleted in liver cancer 1 (DLC-1) is a tumor suppressor gene often lost in cancers. Its RhoGAP activity is crucial, but the exact mechanisms driving DLC-1-related cancers require further investigation for therapeutic development.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Deleted in liver cancer 1 (DLC-1) was first identified in rats and is frequently deleted in human hepatocellular carcinoma (HCC).
  • DLC-1 is generally expressed in normal human and rat tissues.
  • Loss or inactivation of DLC-1 is observed in numerous human cancers, suggesting its role as a tumor suppressor.

Purpose of the Study:

  • To review the literature on Deleted in liver cancer 1 (DLC-1) in cancer.
  • To understand the role of DLC-1 and its associated signaling pathways in tumorigenesis.
  • To identify DLC-1 as a potential therapeutic target in various cancers.

Main Methods:

  • A structured literature search of bibliographic databases was performed.
  • Peer-reviewed research articles were selected based on inclusion/exclusion criteria.
  • The review focused on studies investigating DLC-1's role in cancer development and its mechanisms.

Main Results:

  • DLC-1 functions as a tumor suppressor, evidenced by its inactivation or loss in many human cancers.
  • The RhoGAP (Rho-GTPase activating proteins) activity of DLC-1 is critical for its tumor-suppressive function.
  • DLC-1 and its downstream signaling pathways are emerging as potential therapeutic targets for DLC-1-related cancers.

Conclusions:

  • While DLC-1 is recognized as a potential therapeutic target, the precise molecular mechanisms underlying DLC-1-related cancers remain largely undefined.
  • Further research is needed to elucidate these mechanisms for effective therapeutic strategies.
  • Understanding DLC-1's function is crucial for developing targeted cancer therapies.

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...

Loss of Tumor Suppressor Gene Functions01:12

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-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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
