摘要:
The use of modulators of WRN is described. Activators of WRN may be used to induce growth arrest, apoptosis or proliferative senescence, whereas inhibitors of WRN may be used to reduce growth arrest, apoptosis or proliferative senescence. Methods of identifying modulators of WRN are also described.
摘要:
Methods are described whereby vertebrate skin, hair, wool or fur may be lightened, or darkened, in color by administration of a substance, e.g., peptide, antibody, antibody fragment or DNA sequence encoding a peptide, that modulates the protein kinase C-beta-mediated activation of tyrosinase, the rate-limiting enzyme in melanogenesis.
摘要:
Alterations in the structure of telomeres lead to modulation in the redox state of the cell. Substances which mimic destabilized telomeres, such as t-oligos, have a protective effect on future exposure of a cell to oxidative stress.
摘要:
A method of increasing pigmentation in mammalian skin, as well as protecting mammalian skin against ultraviolet damage, is disclosed. Also disclosed is a method of increasing pigmentation in mammalian cells, as well as a method of enhancing melanin production in mammalian melanocytes. A preparation useful in the present methods is additionally disclosed. The methods comprise administering to the epidermis or to the cells DNA fragments, either single- or double-stranded, or a mixture of both, or deoxynucleotides, in a liposomal preparation or other appropriate vehicle. The preparation includes DNA fragments or deoxynucleotides and an appropriate delivery vehicle, such as liposomes.
摘要:
A method for inducing melanin synthesis in melanocytes, thereby increasing the melanin content of melanocytes and, thus, increasing pigmentation, melanocytes with increased melanin content produced by these methods, and uses thereof.
摘要:
Described are methods for treating hyperproliferative disorders, including cancers, by administering to the affected mammal (e.g., human) an effective amount of a composition comprising one or more oligonucleotides which share at least 33% but less than 100% nucleotide sequence identity with the human telomere overhang repeat. Methods of treatment or prevention of hyperproliferative diseases or pre-cancerous conditions affecting epithelial cells, such as psoriasis, atopic dermatitis, or hyperproliferative diseases of other epithelia and methods for reducing photoaging, or oxidative stress or for prophylaxis against or reduction in the likelihood of the development of skin cancer, are also disclosed. The compositions and methods are also useful for treating other cancers, such as for example pancreatic cancer and eradicating cancer stem cells.

摘要:
Methods to control, or manipulate, melanocyte and keratinocyte cell death are disclosed. In particular, a method of preventing epidermal melanocyte cell loss due to injury in a vertebrate is disclosed. Also disclosed is a method of inducing hair growth in a vertebrate, a method of inducing hair color in a vertebrate, a method of inducing skin color in a vertebrate, a method of treating baldness in an individual, and a method of treating alopecia areata in an individual.
摘要:
Methods of treatment or prevention of hyperproliferative diseases or pre-cancerous conditions affecting epithelial cells, such as psoriasis, vitiligo, atopic dermatitis, or hyperproliferative or UV-responsive dermatoses, hyperproliferative or allergically mediated diseases of other epithelia and methods for reducing photoaging, or oxidative stress or for prophylaxis against or reduction in the likelihood of the development of skin cancer, are disclosed.
摘要:
Methods of inhibiting &bgr;-amyloid-mediated activation of the p75 nerve growth factor receptor of a cell that expresses the p75 nerve growth factor receptor are provided. Methods of inhibiting the binding of &bgr;-amyloid protein and &bgr;-amyloid peptides to the p75 nerve growth factor receptor, and methods of inhibiting &bgr;-amyloid-mediated apoptosis of neural crest-derived cells are provided. The methods comprise contacting the cell with a substance, comprising, for example, the amino acid sequence lysine-glycine-lysine (KGK) or lysine-glycine-alanine (KGA), wherein the substance binds to the p75 nerve growth factor receptor, resulting in the inhibition of &bgr;-amyloid protein or &bgr;-amyloid peptide binding to and/or activation of the p75 nerve growth factor receptor, or wherein the substance inhibits &bgr;-amyloid protein or &bgr;-amyloid peptide mediated apoptosis of the cell which expresses the p75 nerve growth factor receptor.
