    • The present disclosure encompasses embodiments of a novel near-infrared-emitting molecular fluorophore and probes incorporating said fluorophore advantageous for in vitro and in vivo research studies. The fluorophore is robust, photostable, and possesses functionalities for easy bioorthogonal conjugation (e.g., click chemistry, hydrazone formation, Diels Alder, Staudinger ligation, etc.). It is biocompatible and emits at 711 nm in aqueous conditions. These fluorophores may be used to fluorescently tag biological molecules or structures of interest, or used as optical reporters (i.e., activatable molecular probes, fluorescent dyes) for specific biomarkers/analytes as they can be switched from "off" to "on." This fluorophore is useful for cellular assays and preclinical small animal imaging as the near-infrared emission is highly penetrating, and the photophysical properties are outstanding. As such, the properties of this class of fluorophores could easily be translated for use in clinical applications.
    • 本公开涵盖了新型近红外发射分子荧光团和掺入所述荧光团的探针的实施方案,其有利于体外和体内研究研究。 荧光团是稳定的,光稳定的,并且具有容易的生物正交结合的功能(例如,点击化学,腙形成,狄尔斯·阿德尔,施陶丁格结扎等)。 它是生物相容的,在水性条件下以711nm发射。 这些荧光团可用于荧光标记感兴趣的生物分子或结构,或用作特定生物标志物/分析物的光学记录器(即可激活的分子探针,荧光染料),因为它们可以从“关闭”切换到“开”。 该荧光团对于细胞测定和临床前小动物成像是有用的,因为近红外发射是高度穿透的,并且光物理性质是突出的。 因此,这种类型的荧光团的性质可以容易地被翻译用于临床应用。

    • Glucagon-like peptide-1 (GLP-1 ) is a member of a large family of incretin hormones secreted in nutrient-dependent response. GLP-1 acts on GLP-1 receptor (GLP-1 R) that is highly expressed on pancreatic β-cells. The peptide has great potential for development of diabetes treatment and diagnosis. However, the pharmaceutical effects of the peptide suffer from in vivo instability and short life due to degradation by Dipeptidylpeptidase-1 (DPP-4). The 30 amino acid peptide GLP-1 has been integrated into a stable host protein human calbindin D9k. The fusion protein binds to GLP-1 R as demonstrated by immunostaining analyses of GLP-1 R expressing cells. The fusion protein agents can be useful for both diabetes treatment and GLP-1 R receptor targeting MR imaging. The fusion protein has a size about 14 kDa, which enables efficient tissue penetration and retention, and an extended circulation time, is stable, remaining intact and retaining activity after 48 hours incubation with 75% human serum. The protein retains its native folded structure after boiling for ten minutes forming the basis of an experimental protocol for large scale production of the fusion protein (>30 mg/l bacterial culture). No toxicity has been observed with tests on mice. One aspect of the disclosure, therefore, provides a fusion protein comprising a first peptide characterized by selectively binding to a site of a target cell and linked to a second peptide, where the fusion protein is more stable than the first peptide alone. In embodiments of this aspect of the disclosure, the fusion protein may further comprise a detectable label attached thereto. In some embodiments of this aspect of the disclosure, the first peptide of the fusion protein may be glucagon-like peptide-1 (GLP-1 ), glucagon-like peptide-1 (GLP-1 )(7-36), or glucagon-like peptide-1 (GLP-1 ) (9-36), or a conservative variant thereof.
    • 胰高血糖素样肽-1(GLP-1)是营养依赖性反应中分泌的大肠激素的成员之一。 GLP-1作用于在胰腺β细胞上高表达的GLP-1受体(GLP-1R)。 该肽具有发展糖尿病治疗和诊断的巨大潜力。 然而,由于二肽基肽酶-1(DPP-4)的降解,肽的药物作用遭受体内不稳定性和短寿命。 30个氨基酸的肽GLP-1已经被整合到稳定的宿主蛋白人类calbindin D9k中。 如通过GLP-1R表达细胞的免疫染色分析所证明的,融合蛋白与GLP-1R结合。 融合蛋白剂可用于糖尿病治疗和靶向MR-1的受体受体。 融合蛋白具有约14kDa的大小,其能够有效的组织穿透和保留,并且延长的循环时间是稳定的,在75%人血清孵育48小时后保持完整和保留活性。 蛋白质在煮沸10分钟后保持其天然折叠结构,形成大规模生产融合蛋白(> 30mg / l细菌培养物)的实验方案的基础。 在小鼠试验中没有观察到毒性。 因此,本公开的一个方面提供了包含第一肽的融合蛋白,其特征在于选择性结合靶细胞的位点并连接到第二个肽,其中融合蛋白比单独的第一个肽更稳定。 在本公开的该方面的实施方案中,融合蛋白还可包含附着于其上的可检测标记。 在本公开的该方面的一些实施方案中,融合蛋白的第一肽可以是胰高血糖素样肽-1(GLP-1),胰高血糖素样肽-1(GLP-1)(7-36)或胰高血糖素 样肽-1(GLP-1)(9-36)或其保守变体。

    • A conditionally replicating adenovirus were generated that can specifically replicate and express therapeutic genes in neuroendocrine tumors. The promoter-specific expression of the adenoviruses is regulated upstream by an INSM1 (insulinoma-associated-1) promoter that is silent in normal adult tissues but active in developing neuroendocrine cells and neuroendocrine tumors. By placing the I NSM 1 -promoter with an insulator and two copies of neuronal restrictive silencer elements in an adenoviral vector, the construct can retain tumor specificity and drive expression of a mutated adenovirus E1A gene (Δ24Ε1Α) and the herpes simplex virus thymidine kinase gene. The I NSM1 -promoter-driven viruses could replicate specifically in the I NSM1 -positive cells and I NSM1 -specific HSV-tk expression in combination with ganciclovir treatment displayed dose-dependent tumor cell-specific killing in insulinomas. When the I NSM1 -promoter driven HSV-tk was combined with Δ24Ε1Α and I NSM 1 p- HSV-tk viruses, the co-infected insulinoma expressed higher levels of HSV-tk and more efficient tumor suppression as compared to the I NSM1 p- HSV-tk virus alone.
    • 产生可在神经内分泌肿瘤中特异性复制和表达治疗基因的条件性复制型腺病毒。 INSM1(胰岛瘤相关-1)启动子在上游调节腺病毒的启动子特异性表达,所述启动子在正常成人组织中沉默,但在发育中神经内分泌细胞和神经内分泌肿瘤中有活性。 通过将I NSM1启动子与绝缘子和神经元限制性沉默子元件的两个拷贝置于腺病毒载体中,该构建体可保留肿瘤特异性并驱动突变的腺病毒E1A基因(Δ24E1A)的表达和驱动 单纯疱疹病毒胸苷激酶基因。 I NSM1启动子驱动的病毒可以特异性地在I NSM1阳性细胞中复制,并且I NSM1特异性HSV-tk表达与更昔洛韦治疗组合在胰岛瘤中显示剂量依赖性肿瘤细胞特异性杀伤。 当I NSM1启动子驱动的HSV-tk与Δ24E1A和I NSM1p-HSV-tk病毒组合时,与I NSM1对照相比,共感染的胰岛瘤表达更高水平的HSV-tk和更有效的肿瘤抑制, 仅HSV-tk病毒。
