Background: Despite the growing advances in molecular research and therapeutics, glioblastomas are still considered highly invasive aggressive tumors with a median survival of 15 months. Genetic alterations have been studied in detail; however, additionally, there is now growing evidence on the role of epigenetic alterations in glioblastoma. Recently, histone modification patterns have been found to have a significant part in gene expression and prognosis. However, further research in this field is warranted to establish its role for the betterment of these patients with the deadly disease.

Aims: To determine the immunohistochemical expression of histone modifications like histone-3-lysine-18 acetylation (H3K18Ac) and histone-4-lysine 20 trimethylation (H4K20triMe) in glioblastoma patients.

Materials and methods: This is a retrospective study of 48 glioblastoma patients who underwent surgery. Immunohistochemistry (IHC) for tri-methyl-histone-H4 (Lys20) (H4K20triMe) and acetyl-histone-H3 (Lys18) (H3K18Ac) was performed in paraffin-embedded tissues manually, and the expression was noted. Data on the mitotic index and overall survival was collected and statistically analyzed.

Results: The mean age was 50 years with a M: F ratio of 1.6:1. Out of 48 cases, 60% (28 cases) demonstrated positivity for H3K18Ac and 98% (46 cases) for H4K20triMe. The pattern of expression was nuclear with increased expression adjacent to necrosis and at the invasive front. The overall median Q score for H3K18Ac was 1/12 and for H4K20triMe was 6/12. No significant statistical significance was observed between histone expression, Ki67%, and overall survival.

Conclusion: Histone modification patterns are being explored in detail in an array of tumors. They also have a potential role in glioblastoma for risk stratification and instituting appropriate treatment based on the prognosis. Epigenetic changes like histone modification patterns, in addition to genetics, can pave the way for a better molecular understanding of glioblastomas and provide hope in the future to improve the survival of these patients with deadly diseases.

背景:尽管分子研究和治疗方法不断进步,胶质母细胞瘤仍被认为是侵袭性极强的肿瘤,中位生存期仅为 15 个月。基因改变已被详细研究过,然而,现在有越来越多的证据表明表观遗传改变在胶质母细胞瘤中的作用。最近,人们发现组蛋白修饰模式在基因表达和预后中起着重要作用。目的:确定胶质母细胞瘤患者组蛋白修饰的免疫组化表达,如组蛋白-3-赖氨酸-18乙酰化(H3K18Ac)和组蛋白-4-赖氨酸20三甲基化(H4K20triMe):这是一项回顾性研究,研究对象为接受手术的48例胶质母细胞瘤患者。人工对石蜡包埋组织进行三甲基组蛋白-H4(Lys20)(H4K20triMe)和乙酰组蛋白-H3(Lys18)(H3K18Ac)的免疫组化(IHC),并记录其表达情况。收集有丝分裂指数和总生存率数据并进行统计分析:平均年龄为 50 岁,男女比例为 1.6:1。在 48 个病例中,60%(28 例)显示 H3K18Ac 阳性,98%(46 例)显示 H4K20triMe 阳性。H3K18Ac和H4K20triMe的表达模式为核型,在坏死附近和侵袭前沿表达增多。H3K18Ac 的总体 Q 评分中位数为 1/12,H4K20triMe 为 6/12。组蛋白表达、Ki67%和总生存率之间没有明显的统计学意义:结论:组蛋白修饰模式正在一系列肿瘤中被详细探索。它们在胶质母细胞瘤中也有潜在的作用,可用于风险分层,并根据预后情况进行适当的治疗。除遗传学外,组蛋白修饰模式等表观遗传学变化可为更好地从分子角度了解胶质母细胞瘤铺平道路,并为改善这些致命疾病患者的生存状况带来希望。
