Purpose:
Evading apoptosis is one of the major hallmarks of cancer cells. Inhibitors of apoptosis (IAPs) proteins are considered as a most important gene families involved in apoptosis. BRUCE protein, a member of IAPs, is able to quench apoptosis as well as playing role in cell division. Our aim in this study was to analyze BRUCE protein expression in gastric carcinoma (GC) and its correlation with the clinicopathological features.
Methods:
Using immunohistochemistry, 52 GC specimens were studied for BRUCE protein expression. A validated scoring method was applied.
Results:
BRUCE protein expression was detected in majority of tumor tissues (98.07 %). A significant correlation between gender and BRUCE expression (p = 0.024) was detected. Indeed, females showed higher level of BRUCE expression than male patients.
Conclusion:
Since specific expression of BRUCE protein was revealed in majority of GC tissues, BRUCE protein may be a useful therapeutic target for cancer therapy. Furthermore, based on the native role of BRUCE protein in inhibition of apoptosis, using this protein in targeted therapy of tumor cells may help to inhibit tumor cells growth and survival leading to rapid elimination of tumor mass.
Insights
BRUCE protein, a key inhibitor of apoptosis, is highly expressed in most gastric cancer tissues, particularly in females. This suggests BRUCE may be a promising therapeutic target for gastric cancer treatment.
Area of Science:
- Oncology
- Molecular Biology
- Cellular Biology
Background:
- Cancer cells evade apoptosis, a programmed cell death process.
- Inhibitors of Apoptosis (IAPs) proteins are crucial in regulating apoptosis.
- BRUCE is an IAP family member involved in apoptosis inhibition and cell division.
Purpose of the Study:
- To investigate BRUCE protein expression in gastric carcinoma (GC).
- To correlate BRUCE expression with clinicopathological features of GC.
Main Methods:
- Immunohistochemistry was used to detect BRUCE protein.
- 52 gastric carcinoma specimens were analyzed.
- A validated scoring method was applied for quantification.
Main Results:
- BRUCE protein was expressed in 98.07% of tumor tissues.
- A significant correlation was found between BRUCE expression and gender (p=0.024).
- Female patients exhibited higher BRUCE protein levels compared to male patients.
Conclusions:
- BRUCE protein's specific expression in GC suggests its potential as a therapeutic target.
- Targeting BRUCE may inhibit tumor cell growth and survival, aiding in tumor mass elimination.
- BRUCE's role in apoptosis inhibition makes it a candidate for novel cancer therapies.
