본 연구에서는 미만형 위암조직에서의 임상병리학적 인자와 HSP70, BAG1, Raf-1의 발현간의 상관관계를 평가하고자 하였다. Hsp70은 열충격단백질(heat shock protein)의 환경적 스트레스로부터 세포를 보호하는 분자생물학적 chaperone으로 작용하는 것뿐 아니라 anti-apoptotic 작용을 통하여 암세포의 생존과 전이를 촉진시키는 것으로 알려져 있다. Proto-oncogene의 일종인 Raf는 사람을 포함한 진핵세포의 생장에 관여하는 중요한 신호전달경로인 mitogen-activated protein kinase (MAPK)경로의 중심인자로서 다양한 암에서 그 발현이 증가한다고 알려져 있다. Bcl-2에 결합하여 세포사멸을 저해하는 것으로 처음 보고된 Bcl-2-associated athanogene-1 (BAG-1)은 다양한 암에서 그 발현이 증가된다고 보고되었다. 또한 BAG-1은 HSP70과 상호작용하여 Raf-1-ERK signal pathway와 cell growth를 조절하는 것으로 보고되었다. Hsp70의 발현은 임파절 전이가 있는 경우 24례(64.9%)에서 양성, 13례(35.1%)에서 음성을 보였으며, 임파절 전이가 없는 경우 6례(26.1%)에서 양성, 17례(73.9%)에서 음성을 보여 임파절의 전이가 있는 경우가 임파절 전이가 없는 경우에 비해 유의하게 높은 발현율을 보였다(p=0.007). N-stage에 따른 발현은 N-stage가 증가함에 따라 발현율이 유의하게 증가하였다(p=0.006). BAG1의발현은 전체 대상 환자 중 43례(71.7%)에서 양성, 17례(28.3%)에서 음성소견을 보였으며, 65세 미만에서 65세 이상에 비해 유의하게 높은 발현율을 보였다(p=0.035). RAF1의 경우 전체 대상 환자 중 45례(75.0%)에서 양성, 15례(25.0%)에서 음성소견을 보였으며, BAG1 양성환자에서 RAF1의 발현이 유의하게 증가 하였다(p=0.021). 본연구 결과 Hsp70은 종양의 진행과 상관성이 있을 것으로 생각되어지며, BAG1과 Raf-1은 미만형위 암의 진단적 마커로 유용할 것으로 사료된다.

The aim of this study was to evaluate the relationships between the expression of Heat shock protein70(HSP70), Raf-1 and Bcl-2-associated athanogene-1 (BAG1) protein in diffuse type gastric carcinoma and examine association of HSP70, Raf-1 and BAG1 expression with various clinic-pathological factors and survival. Heat shock protein70 is induced in the cells in response to various stress conditions, including carcinogens. Overexpression of heat shock protein 70 has been observed in many types of cancer. The proto-oncoprotein Raf is pivotal for mitogen-activated protein kinase (MAPK) signaling, and its aberrant activation has been implicated in multiple human cancers. Overexpression of BAG1 protein has been documented in some type of human cancer. BAG1 has been reported to interact with protein involved with a variety of signal pathway, and regulation of cell differentiation, survival and apoptosis. These interaction partners include HSP70 and Raf-1. The percentage of tumors exhibiting HSP70 positivity was significantly in cases of positive lymph node metastasis (64.9%) compared to cases without lymph node metastasis (35.1%, p=0.007). HS70 expression was correlated with pathological N-stage (p=0.006). Expression of BAG1 was detected in the majority of diffuse type gastric carcinoma tissues (71.7%), especially in younger patients (80% vs 52.6%, p=0.035). Furthermore BAG1 expression was correlated with tumor size (p=0.020). Raf-1 expression was found to be significantly associated with tumor size (p=0.005). The result indicate that HSP70 was significantly correlated the progression of diffuse type gastric cancer. Expression of BAG1 and Raf-1 may be used as diagnostic markers for gastric carcinoma.
