Insights

The RhoA/ROCK2 pathway drives cancer progression, metastasis, and therapy resistance by promoting cell division defects. Inhibiting RhoA/ROCK2 may offer new cancer treatment strategies.

Area of Science:

  • Cell Biology
  • Molecular Oncology
  • Cancer Therapeutics

Background:

  • The Rho GTPase signaling pathway regulates fundamental cellular processes like actin organization, motility, and gene transcription.
  • RhoA and its effector ROCK2 are implicated in cancer progression, including epithelial-mesenchymal transition, invasion, and therapy resistance in cancer stem cells.

Purpose of the Study:

  • To review the role of RhoA/ROCK2 signaling in cancer progression mechanisms.
  • To summarize RhoA/ROCK2 inhibitors as potential therapeutic strategies against cancer recurrence and metastasis.

Main Methods:

  • Literature review focusing on RhoA/ROCK2 signaling in cancer.
  • Analysis of studies investigating the link between Rho signaling, cell division, and cancer stem cell properties.
  • Compilation of data on existing and potential RhoA/ROCK2 inhibitors.

Main Results:

  • RhoA/ROCK2 signaling is crucial for cancer cell migration, invasion, and the development of therapy resistance.
  • Mitotic defects and cytokinesis failure mediated by Rho signaling contribute to polyploidization, promoting tumor recurrence and metastasis.
  • Targeting RhoA/ROCK2 signaling presents a promising avenue for overcoming treatment resistance.

Conclusions:

  • RhoA/ROCK2 signaling plays a significant role in driving cancer progression and therapeutic challenges.
  • Inhibitors targeting the RhoA/ROCK2 pathway hold potential for improving cancer treatment strategies and preventing relapse.

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.

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:

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...

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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
