    • Compositions and methods relating to small interfering RNA (siRNA) polynucleotides are provided as pertains to modulation of biological signal transduction. Shown are siRNA polynucleotides that interfere with expression of members of the protein tyrosine phosphatase (PTP) class of enzymes that mediate signal transduction, and with certain MAP kinase kinases (MKK). In certain preferred embodiments siRNA modulate signal transduction pathways comprising SHP2, cdc14a/b, cdc25A/B/C, KAP, PTP-ε, PRL-3, CD45, dual specificity phosphatase-3 (DSP-3), MKK-4, and/or MKK-7. Modulation of PTP-mediated biological signal transduction has uses in diseases associated with defects in cell proliferation, cell differentiation and/or cell survival, such as metabolic disorders (including diabetes and obesity), cancer, autoimmune disease, infectious and inflammatory disorders and other conditions. The invention also provides siRNA polynucleotides that interfere with expression of chemotherapeutic target polypeptides, such as DHFR, thymidylate synthetase, and topoisomerase I.

    • The present invention describes recombinant adenoviral vectors modified by incorporating targeting ligands or label into viral capsid or structural proteins. In one embodiment, single-chain antibody was introduced into the minor capsid proteins pIIIa or pIX so that the adenoviral vector can be targeted to a particular cell type. In another embodiment, there is provided a noninvasive imaging strategy useful for monitoring the replication and spread of conditionally replicative adenoviral vectors. Viral structural proteins such as pIX capsid protein, core proteins mu, V and VII were expressed as fusion protein with a fluorescent label. Once incorporated into the virions, detection of the structural fusion protein label would indicate the localization of the disseminated viral progeny. The detected fluorescent signals also closely correlate with the level of viral replication and progeny production.
    • 本发明描述了通过将靶向配体或标记掺入病毒衣壳或结构蛋白而修饰的重组腺病毒载体。 在一个实施方案中,将单链抗体引入次要衣壳蛋白pIIIa或pIX中,使得腺病毒载体可靶向特定细胞类型。 在另一个实施方案中,提供了可用于监测条件复制型腺病毒载体的复制和扩散的非侵入性成像策略。 病毒结构蛋白如pIX衣壳蛋白,核心蛋白mu,V和VII被表达为具有荧光标记的融合蛋白。 一旦结合到病毒粒子中,结构融合蛋白标签的检测将指示传播的病毒后代的定位。 检测到的荧光信号也与病毒复制和后代生产水平密切相关。
