Currently, researchers are exploring the conversion of astrocytes into functional mature neurons and gradually exploring the conversion of glioma into neurons. We report that SLCDS (SB431542, LDN193189, CHIR99021, DAPT, and SKL2001) has been shown to convert human glioma cells into mature neuron-like cells. The converted cells exhibited upregulation of DCX, TuJ1, MAP2, NeuN, and GAD67, while the expressions of EGFR, PDGFR, Ki67, and vimentin were inhibited. The nTFs, such as NeuroD1 and Sox2, were upregulated, along with TF genes associated with neurogenesis and tumor suppression. We have finally confirmed that overexpressing nTFs can induce the conversion of glioma cells into neuronal cells. This study demonstrates that SLCDS can activate the expression of nTFs in human glioma cells and induce the conversion of human glioma cells into neuron-like cells. Additionally, SLCDS inhibits the expressions of EGFR, PDGFR, Ki67, and Vimentin in gliomas. Our findings offer a potential approach for treating glioma.
目前，研究人员正在探索将星形胶质细胞转化为功能性成熟神经元，并逐步探索将胶质瘤转化为神经元。我们报告称，SLCDS（SB431542、LDN193189、CHIR99021、DAPT和SKL2001）已被证明可将人胶质瘤细胞转化为成熟的神经元样细胞。转化后的细胞表现出双皮质素（DCX）、微管相关蛋白2（MAP2）、神经元核抗原（NeuN）和谷氨酸脱羧酶67（GAD67）表达上调，而表皮生长因子受体（EGFR）、血小板衍生生长因子受体（PDGFR）、增殖细胞核抗原（Ki67）和波形蛋白的表达受到抑制。神经分化因子1（NeuroD1）和性别决定区Y框蛋白2（Sox2）等神经转录因子（nTFs）上调，同时与神经发生和肿瘤抑制相关的转录因子基因也上调。我们最终证实，过表达nTFs可诱导胶质瘤细胞转化为神经细胞。本研究表明，SLCDS可激活人胶质瘤细胞中nTFs的表达，并诱导人胶质瘤细胞转化为神经元样细胞。此外，SLCDS可抑制胶质瘤中EGFR、PDGFR、Ki67和波形蛋白的表达。我们的研究结果为治疗胶质瘤提供了一种潜在的方法。
