Insights

Rho GTPases regulate cell functions and actin dynamics. Their dysregulation, particularly RhoA, Rac1, and CDC42 overexpression, drives cancer progression through increased cell migration and metastasis.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Biochemistry

Background:

  • Rho GTPases are conserved proteins regulating actin dynamics and intracellular signaling.
  • Key members RhoA, Rac1, and CDC42 are crucial for cell proliferation, gene expression, and apoptosis.
  • Signaling pathways involving RhoGDIs, RhoGEFs, RhoGAPs, and cell surface receptors modulate Rho GTPase activity.

Purpose of the Study:

  • To review the roles of Rho GTPases and their signaling pathways in various cancers.
  • To explore the link between Rho GTPase abnormalities and cancer progression.

Main Methods:

  • Literature review of Rho GTPase function and cancer biology.
  • Analysis of signaling pathways associated with Rho GTPases.
  • Examination of Rho GTPase involvement in cancer hallmarks like migration and metastasis.

Main Results:

  • Rho GTPase overexpression leads to actin cytoskeleton reorganization.
  • Increased Rho GTPase activity correlates with enhanced cell migration, invasion, and metastasis.
  • Aberrant Rho GTPase signaling is implicated in the progression of diverse cancer types.

Conclusions:

  • Rho GTPases are critical regulators of cellular processes relevant to cancer.
  • Understanding Rho GTPase signaling pathways offers potential therapeutic targets for cancer treatment.

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...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins, also known...
