This technology includes methods for screening compounds and compositions useful for inhibiting or reducing platelet deposition, adhesion, and/or aggregation. The present invention further relates to methods of treatment or prophylaxis of thrombotic disorders, including stroke, myocardial infarction, unstable angina, abrupt closure following angioplasty or stent placement, thrombosis induced by peripheral vascular surgery, peripheral vascular disease or thrombotic disorders resulting from atrial fibrillation or inflammation.

This technology includes the use of the Anneal-Pool-Ligate-Sequence method (APLS) to quantify the cellular expression of dozens of genes for high throughput chemical library screening. This method is performed by culturing eucaryotic cells in 384-well format microplates, treating the cells with a library of chemicals, and producing cell lysates. Oligodeoxynucleotide (oligo) pairs representing (21) selected genes, and carrying index sequences for each well (384) and microplate (26), are annealed to mRNAs in cell lysates.

This technology includes a group of 20 drugs that can be further developed as a treatment for chordoma. Chordoma is a rare, slow-growing malignant tumor arising from remnants of the fetal notochord, with a high recurrence rate and no effective chemotherapy agents. These 20 drugs inhibited chordoma cell growth, with potencies ranging from 10 to 370 nM in the chordoma cell line UCH1 cells. These agents also had significant inhibitory effects on chordoma patient cells, C24, C25, and C32.

This technology includes the compositions and methods for inhibiting PIN1 for the treatment of disorders characterized by elevated PIN1 levels (e.g., immune disorders, proliferative disorders, and neurodegenerative disorders) with small molecules. Pin1 dysregulation has been associated with a number of pathological conditions. In particular, PIN1 has been shown to promote oncogenesis by modulating several oncogenic signaling pathways and its overexpression has been shown to correlate with poor clinical outcome.

This invention includes human induced pluripotent stem cell (iPSC) lines that harbor a single copy dCas9-BFP-KRAB at the CLYBL safe harbor locus (mediating CRISPR inhibition of human gene expression) and/or a single copy of dox-inducible NGN2 at the AAVS1 locus (enabling the differentiation of the iPSCs into neurons). The CRISPR-mediated inhibition of human gene expression is maintained into the differentiated neurons, permitting functional studies of targeted genes in neurons.

This technology includes a system that allows for robust differentiation of human-induced pluripotent stem cells (iPSC) into motor neurons within a time frame of 7 to 10 days. To differentiate the iPSC, a stable transgene is inserted into the CLYBL safe harbor locus in the human genome using TALENs. The transgene allows for doxycycline-inducible expression of the transcription factors (NGN2, ISL1, and LHX3) that are needed for the cells to differentiate to motor neurons. The technology is described in detail in the protocol paper published by Fernandopulle et al, cited below.

The technology includes Pink1 knockout HeLa cells that were generated using CRISPR technology. Pink1 is the key master gene to trigger degradation of mitochondria, mitophagy, and is implicated in familial Parkinson Disease. Knocking out Pink1 allows us to study the roles of Pink1 in many aspects of mitophagy and to display Pink1-dependent or independent activity. To create the HeLa cells, two CRISPR gRNAs targeting exon 1 and exon 7 of the Pink1 genome were used for transfection with Cas9 and GFP-C1 reporter. Cells were sorted 2 days after transfection and plated out in 96-well plates.

This invention includes HeLa cells that are engineered to inducibly express a mutant form of ornithine decarboxylase that is targeted to the mitochondrial matrix and forms insoluble protein aggregates. The presence of unfolded proteins in the matrix causes the accumulation of the mitochondrial kinase PINK1 and the E3 ubiquitin ligase PARK2/Parkin. These proteins play a critical role in degrading the mitochondria where they are expressed, a process call mitophagy. Mutations in these two genes are associated with familial Parkinson disease.

This technology includes a series of imidazo[1,2-b]pyridazines that display potent inhibition of FLT3, as well as potent binding and activity against FLT3 tyrosine kinase domain and gatekeeper mutations. This chemotype exhibits superior anti-leukemic activity against the common clinically-relevant FLT3-mutant acute myeloid leukemia (AML) in vitro and in vivo. Tyrosine kinase domain mutations are a common cause of acquired resistance to FLT3 inhibitors used to treat FLT3-mutant AML.
