The compositions comprise antisense compounds, particularly antisense oligonucleotides, targeted to nucleic acids encoding forkhead box O1A. Methods of using these compounds for modulation of forkhead box O1A expression and for treatment of diseases associated with expression of forkhead box O1A are provided, in particular, for methods of treating diabetes.
摘要:
Expression of the E4 orf 1 gene of Ad-36 alone has been discovered to be responsible for the increased insulin sensitivity observed in Ad-36 infected animals, including increased adipogenesis. Ad-36 E4 orf 1 protein can be used to increase insulin sensitivity and ameliorate diabetes. Additionally, drugs that mimic the action of Ad-36 E4 orf 1 protein could be found. Ad-36 E4 orf 1 could also be used to increase fat cells in lipodystrophy. We have also discovered that Ad-36 infection in human skeletal muscle cells increased differentiation and insulin independent glucose uptake. It is expected that infection with Ad-36 E4 orf 1 gene will also cause these effects.

Oligonucleotides directed against the hypoxia-inducible factor-1α (HIF-1α) gene are provided for modulating the expression of HIF-1α. The compositions comprise oligonucleotides, particularly antisense oligonucleotides, targeted to nucleic acids encoding the HIF-1α. Methods of using these compounds for modulation of HIF-1α expression and for the treatment of diseases associated with the hypoxia-inducible factor-1α are provided. Examples of diseases are cancer and pre-eclampsia. The oligonucleotides may be composed of deoxyribonucleosides, a nucleic acid analogue, or Locked Nucleic Acid (LNA) or a combination thereof.

Mammalian subjects having a neoplasm are treated with a virus, a fluoropyrimidine, for example 5-fluorouracil, and a camptothecin compound. The virus is selected from the group consisting of a Newcastle disease virus, a measles virus, a vesicular stomatitis virus, an influenza virus, a Sindbis virus, a picornavirus, and a myxoma virus.
摘要:
Methods and compositions for modulating aging genes or their targets for the treatment or prevention of senescence or symptoms thereof have been developed based on the discovery of naturally occurring inhibitory nucleic acids, in particular lin-4 miRNA, that downregulate genes involved in senescence, lifespan, or age-related disorders. Representative aging genes include, but are not limited to lin-4, lin-14, let-7, lin-28, egl-35 and lin-42. Methods for identifying modulators of aging genes and targets of aging genes are also provided. The disclosed compositions are useful as diagnostics. These can be used in assays to compare genes in normal individuals, with those who are aging well or who demonstrate early senescence, and with those who have age-related disorders such as Parkinson's and Alzheimer's. The genes can be used to study the pathways and mechanisms involved in aging and age-related disorders. These genes can be used as drug targets, or in drug design, to develop drugs that can inhibit one or more characteristics of senescence or age-related disorders. These compositions should be effective therapies for treating or slowing the effects of one or more symptoms or characteristics of age-related disorders resulting from activation or over-expression of aging genes. Compositions that alter the expression of particular aging genes affecting the insulin-like signal pathway are described. Suitable compositions described herein include, inhibitory nucleic acids and small molecules, in particular miRNA.
摘要:
A method and kit for inhibiting the proliferation of cancer cells are disclosed, based on a combination of a proteasome inhibitor and a telomerase inhibitor. When used in cancer therapy, the two compounds in combination enhance the anti-cancer treatment efficacy obtained with the proteasome inhibitor alone or the telomerase inhibitor alone. Preferably, efficacy is supraadditive or synergistic in nature relative to the combined effects of the individual agents, with minimal exacerbation of side effects.
摘要:
The present invention is a recombinant vector encoding and expressing at least three or more costimulatory molecules. The recombinant vector may additionally contain a gene encoding one or more target antigens or immunological epitope thereof. The synergistic effect of them costimulatory molecules on the enhanced activation of T cells is demonstrated. The degree of T-cell activation using recombinant vectors containing genes encoding three costimulatory molecules was far greater than the sum of recombinant vector constructs containing one costimulatory molecule and greater that the use of two costimulatory molecules. Results employing the triple costimulatory vectors were most dramatic under conditions of either low levels of first signal or low stimulator to T-cell ratios. This phenomenon was observed with both isolated CD4+and CD8+T cells. The recombinant vectors of the present invention are useful as immunogenes and vaccines against cancer and pathogenic micro-organisms, and in providing host cells, including dendritic cells and splenocytes with enhanced and antigen-presenting functions.
