疾病背景介紹
BCL6(B細胞淋巴瘤6)正在成為關(guān)鍵的蛋白和治療目標。BCL6首先被確定為受擴散性大B細胞淋巴瘤(DLBLs)中染色體轉(zhuǎn)移影響的部位(1)。然而,現(xiàn)在已知它被廣泛表達在許多淋巴瘤,無論遺傳病變。它在淋巴瘤生成中的作用源于它在幽默免疫系統(tǒng)中的功能,在幽默免疫反應(yīng)(2-4)期間,需要對BCL6進行調(diào)節(jié),以形成細菌中心(GC)。GC 是響應(yīng)抗原刺激而形成的瞬態(tài)結(jié)構(gòu)。
探針描述
BCL6是一種雙色斷裂探針,由兩個直接標記再3q27處的探針構(gòu)成,其中紅色熒光直接標記的探針于BCL6 5’端進行雜交,綠色熒光標記的探針于BCL6 3’端進行雜交。
臨床意義
B細胞淋巴瘤是一種臨床上異質(zhì)和病理上多樣化的疾病組,具有很強的表觀遺傳成分。B細胞淋巴瘤6(BCL6)基因編碼一個轉(zhuǎn)錄因子,通過保持表觀遺傳和轉(zhuǎn)錄狀態(tài),對細胞增殖和DNA損傷至關(guān)重要。BCL6的活動可以通過各種機制解除管制,并有助于B細胞淋巴瘤的發(fā)展。
