mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

5.0K
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.
The mTOR pathway or the...

PI3K/mTOR/AKT Signaling Pathway

6.2K
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...

The Ras Gene

7.5K
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...

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

5.7K
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:

Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

20.6K
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Rho-associated coiled-coil containing protein kinases (ROCK) are known regulators of the actin cytoskeleton.
  • Dysregulation of ROCK signaling has been implicated in various diseases, including cancer.

Purpose of the Study:

  • To investigate the role of ROCK proteins in tumor formation and progression.
  • To determine the specific mechanisms by which ROCK proteins influence tumorigenesis.

Main Methods:

  • Utilized genetically engineered mouse models to study tumor development.
  • Employed molecular biology techniques, including Western blotting and immunohistochemistry, to analyze protein expression and activity.
  • Assessed tumor growth, metastasis, and overall survival in the mouse models.

Main Results:

  • ROCK proteins were found to be significantly upregulated in tumor tissues compared to normal tissues.
  • Inhibition of ROCK activity led to reduced tumor growth and decreased incidence of metastasis in mice.
  • ROCK signaling was shown to promote cancer cell proliferation, migration, and invasion.

Conclusions:

  • ROCK proteins are key drivers of tumor formation and progression in mice.
  • Targeting ROCK signaling pathways presents a potential therapeutic strategy for cancer treatment.
