摘要:
Compositions and methods for enhancing targeted gene editing and methods of use thereof are disclosed. In the most preferred embodiments, gene editing is carried out utilizing a gene editing composition such as triplex-forming oligonucleotides, CRISPR, zinc finger nucleases, TALENS, or others, in combination with a gene modification potentiating agent such as stem cell factor (SCF), a CHK1 or ATR inhibitor, or a combination thereof. A particular preferred gene editing composition is triplex-forming peptide nucleic acids (PNAs) substituted at the γ position for increased DNA binding affinity. Nanoparticle compositions for intracellular delivery of the gene editing composition are also provided and particular advantageous for use with in vivo applications.

摘要:
Methods and agents for suppressing expression of a mutant allele of a gene and providing a replacement nucleic acid are provided. The methods of the invention provide suppression effectors such as, for example, antisense nucleic acids, ribozymes, or RNAi, that bind to the gene or its RNA. The invention further provides for the introduction of a replacement nucleic acid with modified sequences such that the replacement nucleic acid is protected from suppression by the suppression effector. The replacement nucleic acid is modified at degenerate wobble positions in the target region of the suppression effector and thereby is not suppressed by the suppression effector. In addition, by altering wobble positions, the replacement nucleic acid can still encode a wild type gene product. The invention has the advantage that the same suppression strategy could be used to suppress, in principle, many mutations in a gene. Also disclosed is a transgenic mouse that expresses human rhodopsin (modified replacement gene) and a transgenic mouse that expresses a suppression effector targeting rhodopsin. Also disclosed in intraocular administration of siRNA.

The invention provides compositions and methods related to human telomerase reverse transcriptase (hTRT), the catalytic protein subunit of human telomerase. The polynucleotides and polypeptides of the invention are useful for diagnosis, prognosis and treatment of human diseases, for changing the proliferative capacity of cells and organisms, and for identification and screening of compounds and treatments useful for treatment of diseases such as cancers.
摘要:
The invention concerns an antigenic oilgonucleotide hybridizing specifically with the gene encoding human tyrosinase through Hoogsteen pairing between complementary bases, said oligonucleotide forming a triple-helix structure with the human tyrosinase gene. The invention also concerns the use of said oligonucleotide as depigmenting or skin-whitening agent in a cosmetic composition or in a dermatological composition.
