When human histiocytic lymphoma cell line, U937 cells, was treated with cadmium for 12 hours, evidence of apoptotic features, including change in nuclear morphology, DNA fragmentation, formation of DNA ladder in agarose gel electrophoresis, and phosphatidylserine externalization, were obtained.

人淋巴瘤细胞株（U937）暴露于镉12小时后，细胞呈现典型的凋亡特征，包括细胞核形态学改变、DNA梯形条带的形成、及细胞膜磷脂酰丝氨酸外翻转。

The term"homeodomain"has evolved to define a class of protein domains that has recognizable similarity to a 60 amino acid motif (encoded by 180 bp homeobox sequences) originally recognized in three Drosophila homeotic and segmentation proteins. The homeodomains that have been tested contain sequence-specific DNA binding activities and are part of larger proteins that function as transcriptional regulators.

其中一类转录因子通过同源域结合特定的DNA序列，这种特殊的转录因子都包含一个同源盒，它有180bp序列可以编码DNA结合同源域，称同源盒基因（Homeobox gene，Hox gene），带有同源框的基因经过转录产生带有同源域的蛋白质。
