. The public's health has been seriously threatened by cervical cancer during recent times. In terms of newly diagnosed cases worldwide, it ranks as the ninth most prevalent malignancy. Multiple investigations have proven that nanoparticles can effectively combat cancer due to their small dimensions and extensive surface area. In the meantime, bioactive compounds which are biocompatible are being loaded onto nanoparticles to promote cancer therapy. The current study investigates the anticancerous potential of Brucine-entrapped titanium oxide nanoparticles (TiO NPs) in cervical cancer cell line (HeLa). . The physiochemical, structural, and morphological aspects of Brucine-entrapped TiO NPs were evaluated by UV-visible spectrophotometer, Fourier transform-infrared spectroscopy (FT-IR), dynamic light scattering (DLS), scanning electron microscopy (SEM), and energy dispersive X-ray (EDAX). The cytotoxic effect against the HeLa cell line was assessed using a tetrazolium-based colorimetric assay (MTT), a trypan blue exclusion (TBE) assay, phase contrast microscopic analysis, and a fluorescence assay including ROS and DAPI staining. Furthermore, estimation of antioxidant markers includes catalase (CAT), glutathione (GSH), and superoxide dismutase (SOD). . The UV spectrum at 266 nm revealed the formation of TiO NPs. The FT-IR peaks confirmed the effective entrapment of brucine with TiO NPs. The average size (100.0 nm) of Brucine-entrapped TiO NPs was revealed in DLS analysis. The micrograph of the SEM revealed the formation of ellipsoidal to tetragonal-shaped NPs. The Ti, O, and C signals were observed in EDAX. In MTT assay, Brucine-entrapped TiO NPs showed inhibition of cell proliferation in a dose-wise manner and IC was noticed at the concentration of 30 g/mL. The percentage of viable cells gradually reduced in the trypan blue exclusion assay. The phase contrast microscopic analysis of Brucine-entrapped TiO NP-treated cells showed cell shrinkage, cell wall deterioration, and cell blebbing. The intracellular ROS level was increased in a dose-wise manner when compared to control cells in ROS staining. The condensed nuclei and apoptotic cells were increased in treated cells, as noted in DAPI staining. In treated cells, the antioxidant markers such as CAT, GSH, and SOD levels were substantially lower compared to the control cells. . The synthesized Brucine entrapped TiO NPs exhibited remarkable anticancer activity against the HeLa cell line.
近年来,宫颈癌严重威胁着公众健康。就全球新诊断病例而言,它是第九大最常见的恶性肿瘤。多项研究证明,纳米颗粒因其尺寸小和表面积大而能有效对抗癌症。与此同时,具有生物相容性的生物活性化合物正被负载到纳米颗粒上以促进癌症治疗。当前研究调查了载有马钱子碱的二氧化钛纳米颗粒(TiO NPs)对宫颈癌细胞系(HeLa)的抗癌潜力。通过紫外可见分光光度计、傅里叶变换红外光谱(FT-IR)、动态光散射(DLS)、扫描电子显微镜(SEM)和能量色散X射线(EDAX)对载有马钱子碱的TiO NPs的物理化学、结构和形态方面进行了评估。使用基于四唑的比色法(MTT)、台盼蓝排斥法(TBE)、相差显微镜分析以及包括活性氧(ROS)和4',6-二脒基-2-苯基吲哚(DAPI)染色的荧光测定法评估了对HeLa细胞系的细胞毒性作用。此外,对抗氧化标志物的评估包括过氧化氢酶(CAT)、谷胱甘肽(GSH)和超氧化物歧化酶(SOD)。266nm处的紫外光谱显示了TiO NPs的形成。FT-IR峰证实了马钱子碱与TiO NPs的有效包封。DLS分析显示载有马钱子碱的TiO NPs的平均尺寸为100.0nm。SEM显微照片显示形成了椭圆形至四边形的纳米颗粒。在EDAX中观察到了Ti、O和C信号。在MTT试验中,载有马钱子碱的TiO NPs呈剂量依赖性抑制细胞增殖,在浓度为30μg/mL时观察到半数抑制浓度(IC)。在台盼蓝排斥试验中,活细胞百分比逐渐降低。载有马钱子碱的TiO NP处理细胞的相差显微镜分析显示细胞收缩、细胞壁恶化和细胞起泡。与对照细胞相比,在ROS染色中细胞内ROS水平呈剂量依赖性增加。如DAPI染色所示,处理细胞中的浓缩细胞核和凋亡细胞增加。在处理细胞中,与对照细胞相比,CAT、GSH和SOD等抗氧化标志物水平显著降低。合成的载有马钱子碱的TiO NPs对HeLa细胞系表现出显著的抗癌活性。
