Stat3 as a theranostic indicator
This invention relates, e.g., to a method for predicting the response of a subject having estrogen-receptor-positive breast cancer to an inhibitor of the estrogen signaling pathway (e.g. tamoxifen), comprising measuring in a cancer sample from the subject the level of phosphorylation, compared to a baseline value, of one or more of the following members of an interconnected intracellular signaling pathway: (a) 4EBP1, and / or (b) p70S6, and / or (c) STAT3, and / or (d) FAK, wherein a significantly elevated level of phosphorylation of 4EBP1, and / or p70S6 and / or STAT3, and / or a significantly decreased level of phosphorylation of FAK, compared to the baseline value, indicates that the subject is likely to be a non-responder to the inhibitor and / or has a poor prognosis. Additional members of the intracellular signaling pathway whose phosphorylation can be measured are also described. Also described is a method for treating breast cancer in a subject in need thereof, wherein the subject exhibits an elevated level of phosphorylation of these markers, comprising administering to the subject an effective amount of one or more inhibitors of members of the interconnected intracellular signaling pathway.

Peptides causing formation of compact structure
The present invention relates to compositions and methods comprising peptides with high mutual affinity that, when attached to a protein, assist the protein to fold into a compact structure. By virtue of its stability and binding, this scaffold extends the activity of any contained protein sequence in the presence of cellular and other proteases. This compact structure may have other included functional sequences, which are superior to linear and less constrained peptides for library screening, building structure-biased peptide libraries, and targeting specific intracellular and extracellular compartments. The compositions of the present invention can be displayed on viral, archaeal, prokaryotic and eukaryotic cell surfaces for library screening, drug screening and display. The methods of the present invention are useful for in vivo screening of intracellular effector proteins that modulate signaling pathways, and for identification of interacting proteins in vitro. Therefore, the present invention can be used as a scaffold for gene therapy, for the isolation of new therapeutic drugs, and has potential utilization value for use as a therapeutic agent in physiological fluids.

ActiveUS20140100265A1Promoting axon regenerationSugar derivativesPeptide/protein ingredientsGene deliveryAxon growth
Currently no therapies that provide either protection or restoration of neuronal function for adult onset neurodegenerative diseases such as Parkinson's disease exist. Many clinical efforts to provide such benefits by infusion of neurotropic factors have failed. An alternative approach such as viral construct transduction may be used to directly activate the intracellular signaling pathways that mediate neurotrophic effects and induce axon growth. Viral construct transduction of dopaminergic neurons with a constitutively active human form of the p70S6K gene—hp70S6K (CA)—was shown to induce axon regeneration from living dopaminergic cell bodies that had no living axons.

A method for regulating cell pathways by using plant hormone GA and small molecular substance pac
The invention provides a method for regulating cell pathway by using plant hormone GA and small molecular substance PAC, and realizes the regulation switch of signal pathway in human cells. The GA receptor proteins GID1 and GAI in Arabidopsis thaliana were constructed on a human cell expression vector, and then transferred into HEK293T cells together. GA was added to induce the interaction between the two proteins. After adding the inhibitor PAC, the degree of interaction would be weakened. In this way, the key proteins in the human cell signaling pathway are fused and expressed with these two receptor proteins. The two receptor proteins interact under the induction of GA, and the fusion signaling pathway is also induced by GA. The present invention selects the key protein LRP6 on the human Wnt pathway. After the fusion expression of GA receptor and LRP6, LRP6 will aggregate under the induction of GA, thereby promoting the production of β-catenin and opening the intracellular signaling pathway. After adding PAC inhibition, the production of β-catenin is reduced and the cell pathway is closed.

Application of FAK (focal adhesion kinase) inhibitor in treatment of autosomal dominant polycystic kidney disease

The invention proves, through the application of an MDCK (Madin-Darby canine kidney cells) vesicular model, that an FAK (focal adhesion kinase) inhibitor can inhibit the generation and growth of vesicles, can determine intrarenal pharmacological activity of the FAK inhibitor through an in-vitro embryonal vesicular model, and can inhibit the progress of intrarenal vesicles significantly. The invention further proves finally, in a polycystic renal mouse model, that the FAK inhibitor can also inhibit the progress of vesicles in vivo, while the in-vitro and in-vivo vesicular inhibitory actions arein dose-effect relationship. The FAK inhibitor never affects the activity of renal cells; it is indicated that the ability of the FAK inhibitor to polycystic kidney is irrelevant to its cytotoxicity,and that the FAK inhibitor can regulate intracellular signal pathways, which may be one of its important mechanisms to inhibit the progress of renal vesicles. The FAK inhibitor is VS4718 which is suitable for treating autosomal dominant polycystic kidney disease.
