Abstract:
Regulated proteolysis of cellular factors is pivotal to tissue development and homeostasis, whereas uncontrolled proteolytic activity is linked to disease. Type II transmembrane serine proteases (TTSPs) are expressed at the cell surface and are thus ideally located to regulate cell-cell and cell-matrix interactions. Increasing evidence demonstrates that aberrant expression of TTSPs is a hallmark of several cancers and recent studies have defined molecular mechanisms underlying TTSP-promoted carcinogenesis. In addition, new findings suggest that influenza and other respiratory viruses could exploit TTSPs to promote their spread, making these proteases potential targets for intervention in cancer and viral infections. Here, we review the role of TTSPs in tumorigenesis and viral infection and discuss potential approaches to therapy.
Insights
Type II transmembrane serine proteases (TTSPs) regulate cell interactions. Aberrant TTSP activity drives cancer and aids viral spread, presenting therapeutic targets for both diseases.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Regulated proteolysis is crucial for tissue development and homeostasis.
- Uncontrolled proteolytic activity is associated with various diseases.
- Type II transmembrane serine proteases (TTSPs) are cell-surface enzymes regulating cell-cell and cell-matrix interactions.
Purpose of the Study:
- To review the role of TTSPs in tumorigenesis.
- To review the role of TTSPs in viral infections.
- To discuss potential therapeutic strategies targeting TTSPs.
Main Methods:
- Literature review of studies on TTSPs in cancer and viral infections.
- Analysis of molecular mechanisms underlying TTSP function.
- Synthesis of current research on TTSP-targeted therapies.
Main Results:
- Aberrant TTSP expression is a hallmark of several cancers.
- Specific molecular mechanisms link TTSPs to carcinogenesis.
- Respiratory viruses, including influenza, may utilize TTSPs for propagation.
Conclusions:
- TTSPs are implicated in both cancer development and viral pathogenesis.
- Targeting TTSPs offers potential therapeutic avenues for cancer and viral infections.
- Further research is warranted to develop effective TTSP-based interventions.
