Plant derived products have steadily gained momentum in treatment of cancer over the past decades. Curcuma and its derivatives, in particular, have diverse medicinal properties including anticancer potential with proven safety as supported by numerous in vivo and in vitro studies. A defective Mis-Match Repair (MMR) is implicated in solid tumors but its role in haematologic malignancies is not keenly studied and the current literature suggests that it is limited. Nonetheless, there are multiple pathways interjecting the mismatch repair proteins in haematologic cancers that may have a direct or indirect implication in progression of the disease. Here, through computational analysis, we target proteins that are involved in rewiring of multiple signaling cascades via altered expression in cancer using various curcuma derivatives (Curcuma longa L. and Curcuma caesia Roxb.) which in turn, profoundly controls MMR protein function. These biomolecules were screened to identify their efficacy on selected targets (in blood-related cancers); aberrations of which adversely impacted mismatch repair machinery. The study revealed that of the 536 compounds screened, six of them may have the potential to regulate the expression of identified targets and thus revive the MMR function preventing genomic instability. These results reveal that there may be potential plant derived biomolecules that may have anticancer properties against the tumors driven by deregulated MMR-pathways.
在过去几十年中,植物衍生产品在癌症治疗方面稳步发展。特别是姜黄及其衍生物具有多种药用特性,包括已被大量体内和体外研究证实的抗癌潜力和安全性。缺陷错配修复(MMR)与实体瘤有关,但在血液恶性肿瘤中的作用尚未得到深入研究,目前的文献表明其作用有限。尽管如此,在血液癌症中,有多个途径介入错配修复蛋白,这些途径可能直接或间接影响疾病的进展。在这里,我们通过计算分析,针对使用各种姜黄衍生物(姜黄和莪术)在癌症中通过改变表达而参与多条信号通路重布线的蛋白质,这些衍生物反过来又能深刻控制 MMR 蛋白功能。筛选这些生物分子以确定它们在选定靶点(血液相关癌症)上的疗效;这些靶点的异常会对错配修复机制产生不利影响。研究表明,在筛选的 536 种化合物中,有 6 种可能具有调节已鉴定靶点表达的潜力,从而恢复 MMR 功能,防止基因组不稳定性。这些结果表明,可能存在具有抗癌特性的植物衍生生物分子,可以针对由 MMR 途径失调驱动的肿瘤。
