中文摘要
SMARCA1在RMS组织中高表达,但在肌肉组织中不表达。此外,我们还发现在横纹肌肉瘤细胞中SMARCA1与HDAC2相互作用。在肌源性分化过程中,SMARCA1的表达增加。用CRISPR/Cas9基因敲除RH30细胞中SMARCA1的表达。我们正在制造SMARCA1 KO RD细胞。我们将使用ATAC-seq来研究SMARCA1 KO引起的染色质可及性的变化。此外,我们还将检测SMARCA1 KO对这些PAX融合阳性(RH30)和阴性(RD)细胞分化的表型影响。该项目是与朱迪·戴维合作的。
英文摘要
SMARCA1 is expressed highly in RMS tissues but not in muscle tissues. In addition, we show that SMARCA1 interacts with HDAC2 in rhabdomyosarcoma cells. SMARCA1 expression increases during myogenic differentiation. CRISPR/Cas9 was used to knock out SMARCA1 expression in RH30 cells. We are in the process of making SMARCA1 KO RD cells. We will use ATAC-seq to investigate changes in chromatin accessibility as a result of SMARCA1 KO. In addition, we will examine the phenotypic impact of SMARCA1 KO on the differentiation of these PAX-fusion positive (RH30) and negative (RD) cells. The project is in collaboration with Judy Davie.
