Glioblastoma (GBM) is the most common and mortal primary brain tumor in human. After standard therapies, that include surgical resection followed by radiotherapy and chemotherapy, it is difficult to completely remove the tumor and the development of relapses and resistance is almost inevitable. The chemotherapy now available also show important side effects, to overcame those limitation, new platinum-based drugs are being synthetized, Pt(IV)Ac-POA, (OC-6–44)-acetate-diamine-chloride(2-(2-propynyl)octanoato)platinum(IV), a prodrug having an Histone-3-DeAcetylase-Inhibitor as axial ligands, is one of them. Moreover, new compounds of plant origin are increasingly seen as potential sources of benefits in oncological treatments. The aim of the study is to investigate the possible contribution of micotherapy in the fight against GBM, its role in the metabolism of reactive oxygen species (ROS) and its synergic effect with a new platinum-based compound, Pt(IV)Ac-POA, on human glioblastoma U251 cells. Through cytofluorimetric and immunofluorescence analysis, the ability of the micotherapy in study to regulate the cell cycle was assessed, and its importance in controlling the cellular redox state was also revealed, opening to the possibility of a new therapy in which micotherapy can support the activity of new chemotherapy while reducing its side effects controlling inflammatory conditions in the microenvironment. Additionally, the combined therapy appeared able to induce regulated form of necrosis, such as ferroptosis, and to hinder the establishment of resistance mechanisms.

新型联合抗癌疗法的力量:微创治疗多形性胶质母细胞瘤的挑战与机遇

胶质母细胞瘤 (GBM) 是人类最常见和致命的原发性脑肿瘤。在标准治疗后,包括手术切除,然后是放疗和化疗,很难完全切除肿瘤,复发和耐药性的发展几乎是不可避免的。现在可用的化学疗法也显示出重要的副作用,为了克服这些限制,正在合成新的铂类药物,Pt(IV)Ac-POA, (OC-6-44)-acetate-diamine-chloride(2-(2 -propynyl)octanoato)platinum(IV) 是一种前药,具有组蛋白-3-去乙酰化酶抑制剂作为轴向配体,是其中之一。此外,植物来源的新化合物越来越被视为肿瘤治疗的潜在益处来源。该研究的目的是调查微疗法在对抗 GBM 中的可能贡献,它在活性氧 (ROS) 代谢中的作用及其与新的铂基化合物 Pt(IV)Ac-POA 对人胶质母细胞瘤 U251 细胞的协同作用。通过细胞荧光和免疫荧光分析,评估了研究中的微疗法调节细胞周期的能力,并揭示了其在控制细胞氧化还原状态中的重要性,为新疗法提供了可能,其中微疗法可以支持微疗法的活性。新的化学疗法,同时减少其控制微环境中炎症状况的副作用。此外,联合疗法似乎能够诱导调节形式的坏死,例如铁死亡,并阻碍耐药机制的建立。Pt(IV)Ac-POA,在人胶质母细胞瘤 U251 细胞上。通过细胞荧光和免疫荧光分析,评估了研究中的微疗法调节细胞周期的能力,并揭示了其在控制细胞氧化还原状态中的重要性,为新疗法提供了可能,其中微疗法可以支持微疗法的活性。新的化学疗法,同时减少其控制微环境中炎症状况的副作用。此外,联合疗法似乎能够诱导调节形式的坏死,例如铁死亡,并阻碍耐药机制的建立。Pt(IV)Ac-POA,在人胶质母细胞瘤 U251 细胞上。通过细胞荧光和免疫荧光分析,评估了研究中的微疗法调节细胞周期的能力,并揭示了其在控制细胞氧化还原状态中的重要性,为新疗法提供了可能,其中微疗法可以支持微疗法的活性。新的化学疗法,同时减少其控制微环境中炎症状况的副作用。此外,联合疗法似乎能够诱导调节形式的坏死,例如铁死亡,并阻碍耐药机制的建立。并且还揭示了它在控制细胞氧化还原状态中的重要性,从而开启了一种新疗法的可能性,其中微疗法可以支持新化学疗法的活性,同时减少其控制微环境中炎症状况的副作用。此外,联合疗法似乎能够诱导调节形式的坏死,例如铁死亡,并阻碍耐药机制的建立。并且还揭示了它在控制细胞氧化还原状态中的重要性,从而开启了一种新疗法的可能性,其中微疗法可以支持新化学疗法的活性,同时减少其控制微环境中炎症状况的副作用。此外,联合疗法似乎能够诱导调节形式的坏死,例如铁死亡,并阻碍耐药机制的建立。
