The intradermal delivery of an antisense oligonucleotide was examined by iontophoresis. In this experiment, the antisense sequence of [(32)P]-labeled phosphodiester oligonucleotide ([(32)P]D-oligo, 18-mer) hybridizing to mouse interleukin 10 (IL-10) mRNA was used as a model D-oligo. In in vitro iontophoretic experiments, isolated hairless mouse skin was used with a horizontal diffusion cell. Th...

Human B- or T-cell lymphoma lines and primary murine lymphomas were treated with DNA oligonucleotides homologous to the telomere (TTAGGG repeat; "T-oligo"), either alone or in combination with standard, widely-used anticancer chemotherapeutic agents. T-oligo induces cell cycle arrest and apoptosis in cultured human or murine B or T-lymphoma cell lines and primary tumor cells, but exerts no dete...

The poliovirus RNA-dependent RNA polymerase binds cooperatively to single-stranded RNA. We have determined the minimal RNA-binding site size of the poliovirus polymerase using binding titration with oligonucleotides of increasing length. A dramatic increase in affinity was observed when the length of the oligo(U) increased from 8 to 10 nucleotides (nt), arguing that the minimal size of RNA for ...

Eight weeks treatment with Unkei-to induced a significant increase in plasma follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol levels in hyper- (robust) and hypo- (asthenia) functioning patients with first- and second-grade amenorrhea. We observed no significant differences in the rate of change of these hormones between hyper- and hypo-functioning patients. Ovulation o...

Premature ovarian failure is defined as a primary ovarian defect characterized by absent menarche (primary amenorrhea) or premature depletion of ovarian follicles/arrested folliculogenesis before the age of 40 years (secondary amenorrhea). Hormonally, POF is defined by abnormally low levels of estrogen and high levels of FSH, which demonstrate that the ovaries are no longer responding to circul...
