BACKGROUND
Oral cancer is considered as the sixth-most common malignant neoplasm in the world and the most common type is squamous cell carcinoma (SCC). Akt is a serine/threonine-protein kinase, that acts in the regulation of different signaling downstream pathways, including; proliferation, growth, cell metabolism, angiogenesis and survival. The objective of the present study was to show the expression of p-Akt and its prognostic effect in oral SCC (OSCC).
MATERIALS AND METHODS
A total of 72 cases of OSCC were included in this study; the expression of the Akt gene was done on 4 μm tumor sections using immunohistochemical staining of Akt antibody.
RESULTS
Histopathological examination showed that: (43) were GIII, (13) cases were GII, and (16) cases were GI. The positivity of immunohistochemical staining were appear as brown stain. Results showed increase expression of p-Akt in most cases of oral SCC and mean expression about (54.86 ± 31.58), and the expression of p-Akt was increased with the progression of the histological grade of the tumor.
CONCLUSION
High expression of p-Akt and its relation with the progression of tumor grade and invasion of tumor may indicate the relationship between p-Akt expression and aggressiveness and progression of the tumor.
背景
口腔癌被认为是世界上第六大常见恶性肿瘤,最常见的类型是鳞状细胞癌(SCC)。Akt是一种丝氨酸/苏氨酸蛋白激酶,作用于不同信号下游通路的调节,包括增殖、生长、细胞代谢、血管生成和存活。本研究的目的是显示p-Akt在口腔鳞状细胞癌(OSCC)中的表达及其预后作用。
材料与方法
本研究共纳入72例OSCC病例;使用Akt抗体免疫组织化学染色在4μm肿瘤切片上检测Akt基因的表达。
结果
组织病理学检查显示:43例为GIII级,13例为GII级,16例为GI级。免疫组织化学染色阳性表现为棕色染色。结果显示大多数口腔SCC病例中p-Akt表达增加,平均表达约为(54.86±31.58),并且p-Akt的表达随着肿瘤组织学分级的进展而增加。
结论
p-Akt的高表达及其与肿瘤分级进展和肿瘤侵袭的关系可能表明p-Akt表达与肿瘤侵袭性和进展之间的关系。
