摘要:

B细胞慢性淋巴细胞白血病/淋巴瘤6成员B(BCL6B)基因是B细胞/淋巴瘤6(BCL6)的同族体,属于含锌指BTB结构域蛋白(ZBTB)家族,在调控基因表达和细胞增殖中发挥重要作用。BCL6B在多种细胞过程中的功能和潜在的临床应用引起了广泛关注。BCL6B蛋白参与形成转录抑制复合物,并调控Notch和p53等多条关键信号通路。BCL6B在肝细胞癌、胃癌、结直肠癌和乳腺癌等多种实体肿瘤中常因启动子高甲基化而表达下调,发挥抑癌基因功能,参与抑制细胞增殖、迁移和侵袭,并诱导细胞凋亡和周期停滞;BCL6B在分化型甲状腺癌等少数肿瘤中的高表达也提示了其功能的复杂性。鉴于BCL6B表达与肿瘤进展及患者预后的密切关联,BCL6B被视为极具潜力的预后生物标志物和表观遗传治疗靶点。现围绕BCL6B的基因与蛋白结构及其生物学功能进行系统综述,重点阐述其在各类肿瘤发生发展中的作用及相关分子机制的最新研究进展,以期为肿瘤的精准诊疗提供新思路。

Abstract:

B-cell chronic lymphocytic leukemia/lymphoma 6 member B (BCL6B) gene is a homolog of B-cell/lymphoma 6 (BCL6) and belongs to the zinc finger and BTB domain-containing protein (ZBTB) family, playing an important role in regulating gene expression and cell proliferation. The function of BCL6B in various cellular processes and its potential clinical applications have attracted widespread attention. The BCL6B protein participates in the formation of transcriptional repression complexes and regulates multiple key signaling pathways including Notch and p53. In various solid tumors including hepatocellular carcinoma, gastric cancer, colorectal cancer, and breast cancer, BCL6B expression is frequently downregulated due to promoter hypermethylation, functioning as a tumor suppressor gene involved in inhibiting cell proliferation, migration, and invasion, and inducing apoptosis and cell cycle arrest; its high expression in a few tumors such as differentiated thyroid carcinoma also suggests the complexity of its function. Given the close association between BCL6B expression and tumor progression as well as patient prognosis, BCL6B is considered a promising prognostic biomarker and epigenetic therapeutic target. This article systematically reviewed the gene and protein structures and biological functions of BCL6B, with a focus on its role in the occurrence and development of various tumors and the latest research progress on the related molecular mechanisms, aiming to provide new insights for the precision diagnosis and treatment of tumors.
