摘要:
A nucleotide sequence, specifically a CTG triplet repeat, is shown to be expanded in individuals affected with myotonic dystrophy and can be identified in a sample obtained from an individual. Individuals in whom the CTG triplet repeat is present in normal copy number are likely to be minimally affected and individuals in whom the CTG triplet repeat occurs in abnormally high copy number are likely to be more severely affected.
摘要:
The Wilms' tumor gene associated with the 11p13 locus on the human chromosome, as well as a method of analyzing cells for the gene is described and characterized. The gene encodes a transcription unit approximately 50 kb in size and a mRNA of approximately 3 kb, which is expressed in a limited number of cell types (e.g., predominantly kidney cells and ja subset of hematopoietic cells). The polypeptide encoded by the Wilms' tumor DNA includes four "zinc fingers" and a region rich in proline and glutamine, suggesting that the polypeptide has a role in transcription regulation.

Disclosed are methods for the treatment of proliferative disorders using compounds and/or environmental conditions which result in a difference in sensitivity of targeted and non-targeted cells. Certain of the methods involve the identification and use of allele-specific inhibitors of conditionally essential genes.

The Wilms' tumor gene associated with 11p3 locus on the human chromosome, as well as a method of analyzing cells for the gene is described and characterized. The gene encodes a transcription unit approximately 50 kb in size and a mRNA of approximately 3 kb, which is expressed in predominantly in kidney and gonadal tissue. The gene is alternative spliced producing four very similar mRNA transcripts. The polypeptides encoded by the Wilms' tumor DNA includes four "zinc fingers" and a region rich in proline and glutamine, suggesting that the polypeptide has a role in transcription regulation.
摘要:
This invention is directed to a therapeutic strategy, involving (1) identification of alternative alleles of genes coding for proteins vital for cell viability or cell growth and the loss of one of these alleles in cancer cells due to loss of heterozygosity (LOH) and (2) the development of inhibitors with high specificity for the single remaining alternative allele of the vital gene retained by the cancer cell after LOH. The inhibitors of this invention are specific for one alternative allele of a gene that codes for a protein vital to cell viability or cell growth. The targeted gene has two alternative alleles in which the inhibitors of this invention block only the one alternative allele still present in the cancer cells. Exposure to the inhibitor inhibits or kills cancer cells which have undergone LOH. Protein is still capable of being expressed in the normal cells exposed to the inhibitor by the unblocked alternative allele. This differential effect of the inhibitor on cancer cells and normal cells accounts for the high therapeutic index of the inhibitors of this invention when used as antineoplastic agents.
