Abstract

Triple-negative breast cancer (TNBC) poses significant challenges as it lacks specific treatment approaches. In this study, we synthesized niobium-nitrogen-doped titanium dioxide (Nb-NTO) nanoparticles (NPs) functionalized with Mentha arvensis ethanolic and Mucuna pruriens methanolic extracts and evaluated their anti-cancer potential against MDA-MB-231 TNBC cells. The functionalization of doped Nb-NTO NPs with Mentha arvensis and Mucuna pruriens extract exhibited significant synergistic effects, reducing cell viability in a dose-dependent manner with enhanced cytotoxicity at lower concentrations compared to individual treatments. Microscopic analysis revealed morphological changes indicative of apoptosis and necrosis, while flow cytometry demonstrated increased apoptotic and necrotic cell populations in the combination-treated groups. These treatments also significantly reduced the secretion of pro-inflammatory cytokines IL-6 and IL-8, suggesting modulation of the inflammatory tumor microenvironment. Furthermore, the functionalized Nb-NTO NPs effectively targeted cancer stem cell (CSC) properties, inhibiting mammosphere formation and clonogenic survival and downregulating critical CSC markers, including c-Myc, OCT4, and NANOG. This study highlights the potential of Nb-NTO NPs functionalized with Mentha arvensis and Mucuna pruriens as a novel therapeutic strategy for TNBC, addressing key hallmarks of cancer, including apoptosis, inflammation, and CSC targeting. While these findings demonstrate promising in vitro anti-cancer efficacy, further in vivo validation and mechanistic studies are necessary to advance these treatments toward clinical anti-cancer applications.

薄荷和麝香草提取物功能化掺杂Nb-NTO纳米颗粒对MDA-MB-231乳腺癌细胞的细胞毒性和细胞反应
三阴性乳腺癌(TNBC)由于缺乏特定的治疗方法而面临重大挑战。在这项研究中,我们合成了以薄荷乙醇和麻豆甲醇提取物为功能化的铌氮掺杂二氧化钛纳米粒子(Nb-NTO),并评估了它们对MDA-MB-231 TNBC细胞的抗癌潜力。与单独处理相比,薄荷和麻豆提取物对掺杂Nb-NTO NPs的功能化表现出显著的协同效应,在较低浓度下以剂量依赖的方式降低细胞活力,增强细胞毒性。显微镜分析显示凋亡和坏死的形态学变化,而流式细胞术显示联合治疗组凋亡和坏死细胞数量增加。这些治疗还显著降低促炎细胞因子IL-6和IL-8的分泌,提示炎症性肿瘤微环境的调节。此外,功能化的Nb-NTO NPs有效靶向癌症干细胞(CSC)特性,抑制乳腺球形成和克隆存活,下调关键的CSC标志物,包括c-Myc、OCT4和NANOG。这项研究强调了与薄荷和绒毛一起功能化的Nb-NTO NPs作为TNBC的新治疗策略的潜力,解决了癌症的关键特征,包括细胞凋亡、炎症和CSC靶向。虽然这些发现显示出有希望的体外抗癌效果,但为了将这些治疗推向临床抗癌应用,还需要进一步的体内验证和机制研究。

期刊介绍: This journal is devoted to publishing the highest quality innovative papers in the fields of biochemistry and biotechnology. The typical focus of the journal is to report applications of novel scientific and technological breakthroughs, as well as technological subjects that are still in the proof-of-concept stage. Applied Biochemistry and Biotechnology provides a forum for case studies and practical concepts of biotechnology, utilization, including controls, statistical data analysis, problem descriptions unique to a particular application, and bioprocess economic analyses. The journal publishes reviews deemed of interest to readers, as well as book reviews, meeting and symposia notices, and news items relating to biotechnology in both the industrial and academic communities. In addition, Applied Biochemistry and Biotechnology often publishes lists of patents and publications of special interest to readers.
