    摘要: The present invention discloses antisense poly-2′-O-(2,4-dinitrophenyl) oligoribonucleotides which are capable of down regulating the expression of the RIα subunit of protein kinase A. An example is 5′-GGCUGCGUGCCUCCUCACUGG (named antisense poly-DNP RNA-21) or a sequence which has a one-base mismatch therewith. The antisense oligoribonucleotide can be synthesized by in vitro transcription followed by chemical derivatization. The base sequence of the oligoribonucleotides is complementary to that of nt 110 to 130 in RIα/PKA mRNA. The antisense poly-DNP RNA-21 was found to inhibit cell growth with IC50 values in the nanomolar range. These oligonucleotides can be used as effective anti-cancer agents.

    摘要: The present invention provides antisense oligoribonucleotides with sequences that recognize and bind to the c-myc gene or c-myc mRNA, where one or more sugar residues of the oligoribonucleotides are modified by the substitution of DNP at the 2′-O position. The antisense oligoribonucleotides can be used for inhibiting the growth of cells in which the c-myc gene is overexpressed by down-regulation of transcription of c-myc RNA or translation of the c-myc protein. The antisense oligoribonucleotides can also be used for diagnostic purposes to identify the overexpression of the c-myc gene. The nucleotide sequence of the DNP-oligoribonucleotides is complementary to the sequence 578 to 598 in c-myc mRNA and does not contain a G-quartet motif. This DNP-RNA can silence c-myc gene expression both in vitro and in vivo with high efficacy and sequence specificity.

    摘要: Provided are methods and compositions for determining whether an individual has Sjögren's disease (SD). The method entails determining in a biological sample from the individual the presence of antibodies directed to salivary gland protein 1 (SP-I), parotid secretory protein (PSP), carbonic anhydrase 6 (C A6), or determining a combination of the antibodies. Determining that the individual has SD is based on the presence of the antibodies. The method provides for detection of early SD. Kits for antibody detection containing the antigens to which the antibodies of SD patients are directed are also provided.
