Glucocorticoids are effective in inducing apoptosis via the uncharacterized mechanisms in many hematological malignancies. GC-induced apoptosis is initiated by, and strictly dependent upon, the interaction of GC with its receptor, the GR.

糖皮质激素(glucocorticoid，GC)通过与其特异性受体-糖皮质激素受体(glucocorticoid receptor，GR)结合，不仅可诱导未成熟胸腺细胞凋亡，而且对急性白血病细胞、淋巴瘤细胞、骨髓瘤细胞等均有促凋亡作用，诱发凋亡正是应用糖皮质激素治疗白血病的分子生物学基础。

Methods: On the basis of cloning the M-TNF c D NA encoding region,the authors constructed mTNFm,which could potentially expre ss on the c ell surface with a uncleavable type of TNF resulting in deletion of the sequence encoding enzymatic cleavage site of TNF-α-converting enzyme.

PNA hybridizes with DNA or RNA by means of Waston Cricks base pairs complementary with high stability, affinity and selectivity. PNA not only regulates DNA replication, but also adjusts DNA transcription and translation. Many applications have been explored as a new kind of molecular biological tool and a gene targeting strategy.

肽核酸是一类人工合成的核酸类似物，PNA与核酸链以 Waston- Crick碱基配对方式稳定互补结合，具有高度的亲合性、稳定性、特异性特征，PNA能调节基因的表达作用，包括调节基因的复制、转录、翻译过程，因此 PNA有着广泛的分子生物学效应，显示出作为基因调节药物的应用潜力
