Abstract

Amaç: Bu meta-analizde meme kanseri hastalarında östrojen reseptörü (ER) ile YAP protein ifadesi arasın-daki ilişkinin ortaya konulması amaçlanmıştır. YAP proteini, karsinogenez ile ilişkisi bilinen hippo sinyal yolunda efektör bir moleküldür. Mevcut kanıtlar meme kanserinde östrojen reseptörü ile YAP arasındaki ilişkiye dair çelişkiler içermektedir. Meme kanserinde östrojen reseptörü ile YAP ilişkisinin ortaya çıka-rılması YAP’ın rolünü ve terapötik hedef olma potansiyelini anlamaya katkı sağlayacaktır.
Yöntem: Bu çalışmada, birincil araştırmaların birlikte yorumlanmasına olanak veren meta-analiz yöntemi kullanıldı. Çalışmaya YAP ifadesinin immünohistokimyasal olarak belirlendiği dokuz tane birincil çalış-ma dâhil edildi.
Bulgular: Meme kanseri hastalarında yüksek YAP ifadesi ile ER negatifliği arasında anlamlı bir ilişkili olduğu belirlendi (OR=0,739, %95 CI=0,577-0,946, p=0,016). Alt grup analizleri ise, nüklear ve sitoplaz-mik YAP ifadesi ile ER arasında anlamlı bir ilişki olmadığını, hücre genelindeki yüksek YAP ifadesinin ise ER negatifliği ile anlamlı bir ilişkisi olduğunu gösterdi (OR=0,526, %95 CI=0,388-0,712, p=0,000).
Sonuç: YAP ile ER arasında belirlenen ilişki YAP’ın, ER+ tümörlerde daha düşük ifade ile tümör baskıla-yıcı rolünü, ER- tümörlerde ise yüksek ifade ile onkogenik rolünü destekler. Bizim verilerimiz ER- alt tiplerde YAP’ın terapötik potansiyeli olabileceğini destekler. Fakat bu meta-analizde, dahil edilen çalışma sayısının sınırlı olduğu, ağırlıklı olarak Güneydoğu Asya popülasyonuna ait verileri içerdiği ve çalışmala-rın metodolojik farklılıklarının önemli sınırlılığa neden olabileceği unutulmamalıdır.

The relationship between estrogen receptor and YAP expression in breast cancer patients: a meta-analysis study

Abstract

Objectives: This meta-analysis aimed to reveal the relationship between estrogen receptor (ER) and YAP protein expression in breast cancer patients. YAP protein is an effector molecule in the Hippo signaling pathway, which is known to be associated with carcinogenesis. Current evidence is conflicting regarding the relationship between estrogen receptor and YAP in breast cancer. Revealing the relationship between estrogen receptor and YAP expression in breast cancer will contribute to understanding the role of YAP and its potential as a therapeutic target.
Methods: In this study, the meta-analysis method was used, which allows primary studies to be interpre-ted together. Nine primary studies in which YAP expression was determined immunohistochemically were included in our study.
Results: A significant correlation was determined between high YAP expression and ER negativity in breast cancer patients (OR=0.739, 95% CI=0.577-0.946, p=0.016). Subgroup analyzes showed that there was no significant relationship between nuclear and cytoplasmic YAP expression and ER, while high YAP expression throughout the cell had a significant relationship with ER negativity (OR=0.526, 95% CI=0.388-0.712, p=0.000).
Conclusion: The determined relationship between YAP and ER supports the tumor suppressor role of YAP, with its lower expression in ER+ tumors, and its oncogenic role, with its high expression in ER- tumors. Our data support that YAP may have therapeutic potential in ER- subtypes. However, it should be noted that in this meta-analysis, the number of studies included was limited, mainly included data from the Southeast Asian population, and methodological differences of the studies may cause significant limitations.
