  • Publication number: 20210371933
    Abstract: Novel gene deletions and translocations involving chromosome 2 resulting in fusion proteins combining part of Anaplastic Lymphoma Kinase (ALK) kinase with part of a secondary protein have been identified herein in human solid tumors, e.g. non-small cell lung carcinoma (NSCLC). Secondary proteins include Echinoderm Microtubule-Associated Protein-Like 4 (EML-4) and TRK-Fusion Gene (TFG). The EML4-ALK fusion protein, which retains ALK tyrosine kinase activity, was confirmed to drive the proliferation and survival of NSCLC characterized by this mutation. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ALK kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.

  • Publication number: 20210349095
    Abstract: The invention provides the identification of the presence of polypeptides with ROS kinase activity in mammalian lung cancer. In some embodiments, the polypeptide with ROS kinase activity is the result of a fusion between a ROS-encoding polynucleotide and a polynucleotide encoding a second (non-ROS) polypeptide. Three different fusion partners of ROS are described, namely proteins encoded by the FIG gene, the SLC34A2 gene, and the CD74 gene. The invention enables new methods for determining the presence of a polypeptide with ROS kinase activity in a biological sample, methods for screening for compounds that inhibit the proteins, and methods for inhibiting the progression of a cancer (e.g., an lung cancer).

  • Patent number: 11101792
    Abstract: In specific examples, aspects are directed towards eliminating, mitigating or reducing gate loss in circuits including, for example, WBG power devices. One such example is directed towards an apparatus including first and second types of field-effect transistor (FET), where the first type is characterized as being a normally-on FET in a switching-circuit operation with a high-voltage rating, and the second type of FET is characterized as being a normally-off FET in a switching-circuit operation with a voltage rating that is much less than the high-voltage rating of the first type of FET circuit. The FET are arranged in a cascode manner so that, in response to a switching control signal received by the second type of FET circuit, the second type of FET circuit is active to drive the first type of FET.

  • Patent number: 10920756
    Abstract: Microelectromechanical systems (MEMS) devices are described that include a proof mass movably connected to a substrate by accordion springs disposed on opposite sides of the proof mass, with a coupler coupling two of the accordion springs together. The coupler is a bar in some implementations, and may be rigid. The coupler therefore restricts the motion of the accordion springs relative to each other. In this manner, the motion of the proof mass may be restricted to preferred types and frequencies.
