    • In some aspects, described herein is a DNA methylation reporter. In some aspects, the DNA methylation reporter comprises a promoter whose activity can be affected by exogenous methylation changes without being independently regulated by the DNA methylation machinery, operably linked to a DNA sequence that encodes a reporter molecule. In some embodiments the DNA methylation reporter comprises (i) a promoter derived from a mammalian imprinted gene promoter; and (ii) a sequence that encodes a reporter molecule that is detectable in individual mammalian cells, wherein the promoter is operably linked to the sequence that encodes the reporter molecule. Also described are nucleic acids that comprise the DNA methylation reporter, cells that have the DNA methylation reporter integrated into their genome, and non-human mammals comprising cells that have the DNA methylation reporter integrated into their genome.
    • 在一些方面,本文描述的是DNA甲基化报告物。 在一些方面,DNA甲基化报告基因包含启动子,该启动子的活性可受外源甲基化改变的影响,而不受DNA甲基化机制的独立调节,可操作地连接于编码报告分子的DNA序列。 在一些实施方案中,DNA甲基化报告物包含(i)源自哺乳动物印记基因启动子的启动子; 和(ii)编码在各个哺乳动物细胞中可检测的报道分子的序列,其中该启动子与编码报道分子的序列有效连接。 还描述了包含DNA甲基化报告物的核酸,将DNA甲基化报告基团整合到其基因组中的细胞,以及包含将DNA甲基化报告基因整合到其基因组中的细胞的非人哺乳动物。
