Oxidative stress markers have been firmly established as elevated in oral squamous cell carcinomas (OSCCs). These markers play a crucial role in the pathogenic mechanism underlying the accumulation of advanced glycation end products (AGEs) and their respective receptors. The primary objective of this study is to discern and compare the levels of receptors of AGEs (RAGEs) within tissue samples from patients diagnosed with oral submucous fibrosis (OSMF) at varying stages, oral leukoplakia at various stages, and OSCC.
A cross-sectional investigation was conducted, enrolling a total of 49 patients, distributed across three distinct groups. Tissue samples were meticulously collected from the aforementioned patient groups. Subsequently, these samples underwent a process of homogenization and centrifugation. The supernatant obtained was subjected to enzyme-linked immunosorbent assay analysis to precisely determine the concentration of RAGE.
The concentration of RAGEs was found to be significantly higher at various stages of OSMF when compared to the reference group of OSCC ( < 0.05). This difference was statistically significant, indicating a substantial association. In contrast, the levels of RAGE in patients with hyperkeratosis accompanied by epithelial dysplasia at various stages were observed to be lower than those in the OSCC group, with the difference in concentration being statistically insignificant ( > 0.05).
This comprehensive study has provided compelling evidence demonstrating the heightened levels of RAGE in OSMF when compared to OSCC. These findings collectively suggest the potential utility of anti-RAGE interventions as a promising avenue for novel therapeutic strategies in potentially malignant disorders such as OSMF.
氧化应激标志物在口腔鳞状细胞癌(OSCC)中升高已得到确凿证实。这些标志物在晚期糖基化终产物(AGEs)及其各自受体积累的致病机制中起着关键作用。本研究的主要目的是识别和比较不同阶段诊断为口腔黏膜下纤维化(OSMF)、不同阶段口腔白斑和OSCC的患者组织样本中AGEs受体(RAGEs)的水平。
进行了一项横断面研究,共纳入49名患者,分布在三个不同组中。从上述患者组中精心收集组织样本。随后,这些样本经过匀浆和离心过程。获得的上清液进行酶联免疫吸附测定分析,以精确测定RAGE的浓度。
与OSCC参考组相比,OSMF不同阶段的RAGEs浓度显著更高(<0.05)。这种差异具有统计学意义,表明存在显著关联。相比之下,不同阶段伴有上皮发育异常的角化过度患者的RAGE水平低于OSCC组,浓度差异无统计学意义(>0.05)。
这项综合研究提供了有力证据,表明与OSCC相比,OSMF中RAGE水平升高。这些发现共同表明,抗RAGE干预作为一种有前景的新治疗策略,在OSMF等潜在恶性疾病中具有潜在应用价值。
