    摘要: Methods and compositions related to the engineering of a protein with L-cyst(e)ine degrading enzyme activity are described. For example, in certain aspects there may be disclosed a modified cystathionine-γ-lyase comprising one or more amino acid substitutions and capable of degrading L-cyst(e)ine. Furthermore, certain aspects of the invention provide compositions and methods for the treatment of cancer with L-cyst(e)ine using the disclosed proteins or nucleic acids.

    摘要: The present invention relates to nucleic acid constructs comprising selectable marker genes in a multicistronic transcription unit for use in the generation and selection of eukaryotic host cells for expression of a gene product of interest. For increased stringency of selection, the coding sequence of the selectable marker may be directed preceded by a relatively short functional open reading frame to reduce the efficiency of translation of the selectable marker, and/or the amino acid sequence of the selectable marker may comprise one or more mutations that reduce the level of resistance provide by the mutated marker as compared to its wild type counterpart. The invention further relates to methods for generating eukaryotic host cells for expression of a gene product of interest, wherein these nucleic acid constructs are used, and to methods for producing a gene product of interest wherein thus generated host cells are applied.

    摘要: The invention relates to the use of enzymes, nanorods, and nanoelectronic devices to detect cysteine level in a patient sample and relates to the use of the detected cysteine level to predict cancer recurrence in the patient and to prescribe and/or administer an appropriate therapy to a subject. The invention is directed to systems and methods of detecting cysteine level in a sample from a subject, wherein the systems or methods can further comprise measuring at least one additional parameter, such as PSA level, Gleason score and clinical stage. The invention is directed to systems and methods of predicting the probability of a recurrence of a cancer in a subject, wherein the systems or methods can further comprise measuring at least one additional parameter, such as PSA level, Gleason score and clinical stage. The invention further comprises prescribing and/or administering an appropriate therapy to a subject based on the predicted probability of recurrence.
