JHDM2A plays a key role in the occurrence and development of a variety of tumors. However, the molecular mechanism of JHDM2A to promote glycolysis in melanoma is still unclear. We found that JHDM2A expression was increased in melanoma and JHDM2A promoted glycolysis in melanoma cells. MALAT1 were up-regulated when JHDM2A overexpressed while down-regulated when JHDM2A knockdown in melanoma cells. We also found the key miRNA-miR-34a which MALAT1 fuction as ceRNA to modulate. Thus, we hypothesized that JHDM2A promote glycolysis through MALAT1/miR-34a in melanoma. In this study, molecular biology and cell biology methods will be used to investigate the effect and mechanism of JHDM2A to promote glycolysis through MALAT1/miR-34a in melanoma. Clinical melanoma samples and xenograft tumor samples will be used to verify the mechanism. This project will provide new strategies and ideas for JHDM2A based melanoma treatment.
JHDM2A在多种肿瘤的发生、发展中起着关键的作用,但是其在黑色素瘤糖酵解中的作用机制还不清楚。课题组前期研究发现,JHDM2A在黑色素瘤中表达增加,并且在黑色素瘤细胞中可以促进糖酵解,进而发现在黑色素瘤中JHDM2A可以上调MALAT1的表达,并且筛选到MALAT1作为ceRNA调节的关键miRNA-miR-34a。因此,课题组提出JHDM2A通过MALAT1/miR-34a促进黑色素瘤糖酵解的科学假说。课题组拟通过分子生物学和细胞生物学的方法确认JHDM2A通过MALAT1/miR-34a促进黑色素瘤糖酵解,并在人黑色素瘤标本和黑色素瘤小鼠模型中验证该机制。本研究将为基于JHDM2A的黑色素瘤治疗提供新的理论支持和实验基础。
