p53 and its downstream proteins as molecular targets of cancer.
The p53 tumor suppressor gene plays a key role in prevention of tumor formation through transcriptional dependent and independent mechanisms. Transcriptional-dependent mechanisms are mainly mediated by p53 regulation of downstream targets, leading to growth arrest and apoptosis. Mutational inactivation of the p53 gene is detected in more than 50% of human cancers. Mutation of p53 renders cancer...
متن کاملDDSE: downstream targets of the SNF3 signal transduction pathway.
Mutations in the yeast SNF3 gene affect glucose sensing and snf3 mutants show defective growth on glucose. DNA sequence dependent suppressing elements (DDSEs) are regions located in the promoters of yeast glucose transporter (HXT) genes that when present in high copy suppress the snf3 growth defect. Here we provide evidence that the multicopy DDSE suppression is due to the titration of the Rgt1...
متن کاملEstrogen receptors and their downstream targets in cancer.
Estrogen has crucial roles in the proliferation of cancer cells in reproductive organs such as the breast and uterus. Estrogen-stimulated growth requires two estrogen receptors (ERalpha and ERbeta) which are ligand-dependent transcription factors. High expression of ERs is observed in a large population of breast tumors. In addition, the positive expression of ERs correlates with well-different...
متن کاملEvaluation and clinical analyses of downstream targets of the Akt inhibitor GDC-0068.
PURPOSE The oncogenic PI3K/Akt/mTOR pathway is an attractive therapeutic target in cancer. However, it is unknown whether the pathway blockade required for tumor growth inhibition is clinically achievable. Therefore, we conducted pharmacodynamic studies with GDC-0068, an ATP competitive, selective Akt1/2/3 inhibitor, in preclinical models and in patients treated with this compound. EXPERIMENT...
متن کاملGlobal Genome Analysis of the Downstream Binding Targets of Testis Determining Factor SRY and SOX9
A major event in mammalian male sex determination is the induction of the testis determining factor Sry and its downstream gene Sox9. The current study provides one of the first genome wide analyses of the downstream gene binding targets for SRY and SOX9 to help elucidate the molecular control of Sertoli cell differentiation and testis development. A modified ChIP-Chip analysis using a comparat...
