  • Publication number: 20210199640
    Abstract: Viability of cancer cells (e.g., glioblastoma cells) can be reduced by administering mannose to the cancer cells; and applying an alternating electric field with a frequency between 100 and 500 kHz to the cancer cells. Susceptibility to treatment with an alternating electric field can be determined by measuring uptake of a PKM2 probe (e.g., [18F]DASA) before and after treatment with an alternating electric field. Notably, experiments show that the combination of mannose and the alternating electric field produces a synergistic anti-glioblastoma result.

  • Patent number: 9588122
    Abstract: The present disclosure provides methods of treating cancer and modifying a cancer treatment for a cancer with an anti-EGFR drug by creating PRDX6 expression profiles and using the profiles to evaluate and optionally modify treatment. The present disclosure also provides assays and systems for assessing sensitivity of a cancer to an anti-EGFR therapy.

  • Patent number: 9433689
    Abstract: Embodiments of the present disclosure provide for labeled probes such as a 64Cu-FN3 probe (FN3 refers to fibronectin type 3 domain); methods of making labeled probes; pharmaceutical compositions including labeled probes; methods of using labeled probes; methods of diagnosing, localizing, monitoring, and/or assessing non-Hodgkin's lymphoma, cancers, tumors, precancerous cells, and related biological events using labeled probes; kits for diagnosing, localizing, monitoring, and/or assessing non-Hodgkin's lymphoma, cancers, tumors, precancerous cells, and related biological events; and the like.

  • Patent number: 8946391
    Abstract: The present invention provides for a practical, universal and efficient method to ligate two large macromolecules (e.g., proteins) using the alkyne-azide 1,3-dipolar cycloaddition reaction to produce a conjugated macromolecule, such as a multivalent scFv. The present invention also provides for conjugate macromolecules comprising a plurality of macromolecule components cross-linked through at least one linking group comprising at least one 1,2,3-triazole moiety, wherein at least 50 percent of the macromolecule components in the conjugate macromolecule has only one site available for cross-linking.

  • Publication number: 20100179303
    Abstract: A new radioconjugate NP has been developed using recombinant antibody fragments, di-scFv-c (111 In-DOTA-di-scFv-NP) for imaging and therapy of anti MUC-1 10 expressing cancers since aberrant MUC-1 Is abundantly expressed on the majority of human epithelial cancers. Selection and engineering of anti-MUC-1 di-scFv-c (50 kDa) was generated to link NP-M (maleimide). DOTA chelate was conjugated with di-scFv-c for the radiometal chelation to trace the RINP at in vivo. This RINP preparation can provide uniquely high tumor cell binding NP for AMF driven tumor hyperthermia.
