Abstract:
The Transforming Growth Factor-β (TGF-β) mediates embryonic development, maintains cellular homeostasis, regulates immune function, and is involved in a wide range of other biological processes. TGF-β superfamily signaling pathways play an important role in cancer development and can promote or inhibit tumorigenesis. Type III TGF-β receptor (TGFBR3) is a co-receptor in the TGF-β signaling pathway, which often occurs with reduced or complete loss of expression in many cancer patients and can act as a tumor suppressor gene. The reduction or deletion of TGFBR3 is more pronounced compared to other elements in the TGF-β signaling pathway. In recent years, lung cancer is one of the major malignant tumors that endanger human health, and its prognosis is poor. Recent studies have reported that TGFBR3 expression decreases to varying degrees in different types of lung cancer, both at the tissue level and at the cellular level. The invasion, metastasis, angiogenesis, and apoptosis of lung cancer cells are closely related to the expression of TGFBR3, which strengthens the inhibitory function of TGFBR3 in the evolution of lung cancer. This article reviews the mechanism of TGFBR3 in lung cancer and the influencing factors associated with TGFBR3. Clarifying the physiological function of TGFBR3 and its molecular mechanism in lung cancer is conducive to the diagnosis and treatment of lung cancer.
Insights
The Type III TGF-β receptor (TGFBR3) acts as a tumor suppressor in lung cancer. Reduced TGFBR3 expression correlates with increased invasion, metastasis, and poor prognosis, highlighting its inhibitory role.
Area of Science:
- Molecular Biology
- Oncology
- Cell Signaling
Background:
- Transforming Growth Factor-β (TGF-β) signaling is crucial for development and homeostasis.
- TGF-β pathways can either promote or inhibit cancer progression.
- Type III TGF-β receptor (TGFBR3) acts as a co-receptor and often shows reduced expression in cancers, suggesting a tumor suppressor role.
Purpose of the Study:
- To review the mechanism of TGFBR3 in lung cancer.
- To explore factors influencing TGFBR3 expression in lung cancer.
- To elucidate the role of TGFBR3 in lung cancer diagnosis and treatment.
Main Methods:
- Literature review of studies on TGFBR3 and lung cancer.
- Analysis of TGFBR3 expression patterns in lung cancer tissues and cells.
- Examination of the relationship between TGFBR3 expression and lung cancer hallmarks.
Main Results:
- TGFBR3 expression is frequently decreased in various lung cancer types.
- Reduced TGFBR3 expression is linked to increased lung cancer cell invasion, metastasis, and angiogenesis.
- TGFBR3's function is strengthened in inhibiting lung cancer evolution.
Conclusions:
- TGFBR3 plays a significant inhibitory role in lung cancer progression.
- Understanding TGFBR3's function and molecular mechanisms can aid lung cancer diagnosis and treatment.
- Further research into TGFBR3 is warranted for therapeutic strategies.
