Insights

Rho GTPases are crucial cell regulators. Their altered expression, particularly overexpression, is increasingly linked to human cancer development and progression, highlighting their oncogenic potential.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Oncology

Background:

  • Rho proteins, small GTPases, act as molecular switches controlling cellular processes.
  • Early research underestimated their role in cancer due to a lack of identified genetic mutations in tumors.

Purpose of the Study:

  • To review the evidence linking dysregulated Rho GTPase signaling, specifically overexpression, to human tumorigenesis.
  • To highlight the oncogenic activity of certain Rho GTPase family members.

Main Methods:

  • Literature review of studies investigating Rho GTPase expression in human tumors.
  • Analysis of evidence for Rho GTPase involvement in carcinogenic processes.

Main Results:

  • Alterations in Rho GTPase expression levels are detected across various human tumors.
  • Overexpression of specific Rho GTPases contributes to cancer development.

Conclusions:

  • Rho GTPases are implicated in cancer through overexpression, downmodulation, or alterations in their regulatory pathways.
  • Dysregulation of Rho signaling, particularly via overexpression, is a significant factor in human tumors.

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:
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...
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...
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...
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.
