Insights

Deregulation of translation, the process of protein synthesis, is a key factor in cancer cell transformation and metastasis. Understanding these translation changes offers new therapeutic targets for cancer treatment.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Cellular Biology

Background:

  • Translation deregulation is linked to cellular transformation and cancer.
  • Aberrant signaling pathways and translation initiation factors are observed in human cancers.
  • Recent studies highlight translation deregulation's role in cancer metastasis.

Purpose of the Study:

  • To present the latest findings on perturbed translational control in cancer metastasis.
  • To explore how translation deregulation contributes to the metastatic phenotype.

Main Methods:

  • Review of recent studies and findings.
  • Analysis of molecular mechanisms linking translation to metastasis.

Main Results:

  • Translation deregulation selectively affects mRNAs involved in metastasis.
  • Key metastatic steps influenced include migration, invasion, angiogenesis, and survival.

Conclusions:

  • Perturbed translational control is a significant contributor to the metastatic process.
  • Targeting translation offers potential therapeutic strategies for metastatic cancer.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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.

Translational Regulation01:29

Translational Regulation

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...
Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
