    摘要: The entire process of reverse transcription-polymerase chain reaction (RT-PCR) is simplified by using oligonucleotide-immobilized microplates made of, e.g., polypropylene, to which oligonucleotides are securely immobilized and which can be subjected to thermal cycles of PCR. RT-PCR is preferably conducted in solid-phase. Capturing of mRNA and RT-PCR can be conducted in the same plates. The cDNA synthesized from the mRNA captured on the microplates can be used more than once. Further, in combination with the microplates, a filter plate is used for the preparation of cell lysates wherein target cells are placed on the filter plate, and a lysis buffer is passed through the cell layer on the filter to transfer cell lysate directly to the microplate via well-to-well communication.

    摘要: p53-upregulated modulator of apoptosis (PUMA) is a biomarker associated with islet cell health. If PUMA is low, islet cells are typically healthy. If PUMA is high, islet cells are typically unhealthy or dying. PUMA may be measured by either measuring its nucleic or amino acid. PUMA mRNA may be induced by TNF-α stimulation in a time- and dose-dependent manner and β cell apoptosis is induced through a mitochondrial pathway. TNF-α significantly inhibited glucose-induced preproinsulin precursor mRNA synthesis. Such β cell stress signaling in human islets indicates overall state of islet health and, ultimately, the risk of onset and/or degree of severity of both type 1 and type 2 diabetes mellitus.

    摘要: Tumor necrosis factor (TNF) is capable of inducing apoptosis by interacting with specific TNF receptors on the surface of cancer cells. Because multiple members of TNF ligand and receptor are present within each superfamily, over 300 different ligand-receptor combinations exist. Activated blood leukocytes produce TNF as part of the immune response to cancer, as well as producing chemokines to attract other leukocytes to the site. A method is disclosed of detecting significant induction of a variety of TNF superfamily subtype and chemokine mRNAs in blood leukocytes when whole blood is exposed to heat-aggregated IgG or anti-T cell receptor antibodies as a model of immune system interactions. Substantial individual-to-individual variation is observed in TNF subtypes and chemokines induced. Since peripheral blood leukocytes are the supply of anti-cancer immune cells, the quantitation of ex vivo inducibility of appropriate TNF ligands and chemokines in blood will be useful in individualized cancer immunotherapy. If the tumor mass is small, such as with early invisible metastatic lesions, appropriate TNF assaults may be sufficient to prevent relapse.
