An object is to provide a compound capable of inhibiting activation of TGF-β receptors due to HCV, and a screening method for the compound. It has been found that a HCV-derived NS3 protease binds to type I TGF-β receptor, and this binding results in activation of TGF-β receptors. Moreover, binding sites between the NS3 protease and type I TGF-β receptor were identified, and it has been found that antibodies recognizing these binding sites inhibit activation of TGF-β receptors due to NS3 protease. Furthermore, it has been also found that screening for a compound capable of inhibiting activation of TGF-β receptors can be performed by using the inhibition of the binding between NS3 protease and type I TGF-β receptor or the like as an index.

摘要:
The present invention relates to human serine/threonine kinase ULK3 and its ability to regulate GLI transcription factors; mediators of SHH signaling. This disclosure demonstrates that ULK3 enhances endogenous and over-expressed GLI1 and GLI2 transcriptional activity in cultured cells, and ULK3 alters subcellular localization of GLI1. According to this disclosure ULK3 is an autophosphorylated kinase and phosphorylates GLI proteins in vitro. A peptide sequence in GLI1 C-terminus that is phosphorylated by ULK3 is provided in this disclosure. ULK3 catalytical activity is shown to be crucial for its function in SHH pathway. This disclosure shows that serine/threonine kinase ULK3 is involved in the SHH pathway as a positive regulator of GLI proteins. Furthermore, a therapeutic method in SHH dependent human disorders is disclosed by pharmacological inhibition of ULK3 kinase activity. Identification of ULK3 substrate sequence in GLI1 allows the design of peptide-based modulators of its kinase activity.
摘要:
A mechanism of monoamine oxidases (MAOs) driven epithelium-to-mesenchymal transition (EMT) is disclosed. Also disclosed are methods for treating cancer by inhibiting or suppressing MAOs in cancer cells. Novel MAOs inhibitors, such as small molecules, siRNA, shRNA, antisense oligonucleotides, aptamers, decoys, and pharmaceutical compositions useful for treating cancer by disrupting the workings of MAOs are provided. In particular, a class of conjugates formed by covalently conjugating near infrared dye 783, IR-780, and MHI-148 to a MAO inhibitor, such as clorgyline, with and without encapsulation it in a nanoparticle is provided. Other aspects of the invention include methods for forming the nano-conjugates, method for monitoring treatment progress in a cancer patient by monitoring the changes in MAO activity, methods for screening patients who are at risk of cancer or differentiating different forms of cancer by assaying the level and location of MAO activity.
