Abstract:
Cancer survival is largely impacted by the dissemination of cancer cells from the original tumor site to secondary tissues or organs through metastasis. Targets for antimetastatic therapies have recently become a focus of research, but progress will require a better understanding of the molecular mechanisms driving metastasis. Selenoproteins play important roles in many of the cellular activities underlying metastasis including cell adhesion, matrix degradation and migration, invasion into the blood and extravasation into secondary tissues, and subsequent proliferation into metastatic tumors along with the angiogenesis required for growth. In this review the roles identified for different selenoproteins in these steps and how they may promote or inhibit metastatic cancers is discussed. These roles include selenoenzyme modulation of redox tone and detoxification of reactive oxygen species, calcium homeostasis and unfolded protein responses regulated by endoplasmic reticulum selenoproteins, and the multiple physiological responses influenced by other selenoproteins.
Insights
Selenoproteins are crucial in cancer metastasis, influencing cell movement, invasion, and growth. Understanding their roles offers new targets for antimetastatic therapies to improve cancer survival.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Metastasis, the spread of cancer cells, significantly impacts patient survival.
- Antimetastatic therapies are a research focus, necessitating deeper understanding of metastasis mechanisms.
- Selenoproteins are implicated in key cellular processes driving metastasis.
Purpose of the Study:
- To review the multifaceted roles of selenoproteins in cancer metastasis.
- To explore how different selenoproteins may promote or inhibit metastatic progression.
- To highlight selenoproteins as potential therapeutic targets.
Main Methods:
- Literature review of studies on selenoproteins and metastasis.
- Analysis of selenoprotein functions in cellular adhesion, migration, invasion, and angiogenesis.
- Discussion of redox modulation, calcium homeostasis, and unfolded protein responses.
Main Results:
- Selenoproteins are involved in cell adhesion, matrix degradation, migration, and invasion.
- Endoplasmic reticulum selenoproteins regulate calcium homeostasis and unfolded protein responses.

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...
