Insights

The deleted in liver cancer 1 (DLC-1) gene acts as a tumor suppressor. Loss of DLC-1 expression promotes cancer development, while restoring it inhibits tumor growth, highlighting its therapeutic potential.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • The deleted in liver cancer 1 (DLC-1) gene encodes a GTPase activating protein regulating Rho GTPases.
  • Aberrant Rho protein signaling is implicated in cancer development and metastasis.
  • DLC-1 is recognized as a tumor suppressor gene in various human cancers.

Purpose of the Study:

  • To review the biological functions of DLC-1 and its related genes (DLC-2, DLC-3).
  • To summarize the evidence supporting DLC-1's role as a tumor suppressor.
  • To discuss the involvement of DLC-1 and its relatives in neoplasia.

Main Methods:

  • Literature review of studies on DLC-1, DLC-2, and DLC-3.
  • Analysis of genetic and epigenetic mechanisms affecting DLC-1 expression.
  • Evaluation of in vitro and in vivo studies on DLC-1 function.

Main Results:

  • Loss of DLC-1 expression is linked to human cancer development.
  • Restoration of DLC-1 expression inhibits tumor cell growth.
  • DLC-1, DLC-2, and DLC-3 show potential as tumor suppressors.

Conclusions:

  • DLC-1 plays a critical role in suppressing tumor formation.
  • Understanding DLC-1's function is crucial for cancer research and therapy.
  • Related genes DLC-2 and DLC-3 may also possess tumor-suppressive properties.

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:
The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a superfamily...
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...
Activation and Inactivation of G Proteins01:22

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...
Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
