A functional biologically active particle conjugate useful for diagnosis and treating cancer as a bioportal comprises a nanoscale particle having associated therewith an intracellular targeting ligand comprising a PNA, or another nuclease resistant oligonucleotide analog such as MOE-mRNA (2′-methoxyethyl mRNA) or LNA (locked nucleic acid), having a sequence that binds selectively to an uniquely expressed or overexpressed mRNA specific to the cancer or disease state in a living mammal. In one aspect the uniquely overexpressed target specific to the cancer or disease state is the unr mRNA which can be targeted by the antisense sequence PNA50.
一种功能性生物活性颗粒共轭物,用于诊断和治疗癌症,作为生物门户,包括与之相关联的细胞内靶向配体,包括PNA或其他核酸酶抵抗性寡核苷酸类似物,如MOE-mRNA(2'-甲氧基乙基mRNA)或LNA(锁定核酸),具有选择性结合于哺乳动物体内癌症或疾病状态特异性表达或过表达的mRNA序列。在一个方面,特异性过表达的靶点是unr mRNA,可以通过反义序列PNA50进行靶向。
