P53 regulation and function in normal cells and tumors.
Mechanisms to protect organisms from the consequences of DNA damage include the tumor suppressor p53 pathway. p53 protein binds specifically to a DNA consensus sequence to induce growth inhibitory genes or nonspecifically to damaged sites leading to DNA repair or apoptosis. While p53 protein is susceptible to post-translational modifications and binding to other proteins, few of the modificatio...
متن کاملNormal Thyroid Function Tests Following Discontinuation of Levothyroxine in Hypothyroid Iodine Deficient Individuals
SUMMARY In 28 school children with primary hypothyroidism due to iodine deficiency, 100 µg levothyroxine (L-T4} was administered for nine weeks and resulted in normalization of serum T4, T3, and TSH. Five months after withdrawal of L-T 4 , thyroid function was normal in the majority of subjects. Serum T4 was 8.6±2.3 µg/dl ; T3, 156±2.3 ng/dl; and TSH, 6.9± 12.7 µU/ml. Only one subjects showed ...
متن کاملSarcospan-deficient mice maintain normal muscle function.
Sarcospan is an integral membrane component of the dystrophin-glycoprotein complex (DGC) found at the sarcolemma of striated and smooth muscle. The DGC plays important roles in muscle function and viability as evidenced by defects in components of the DGC, which cause muscular dystrophy. Sarcospan is unique among the components of the complex in that it contains four transmembrane domains with ...
متن کاملImpaired p53 expression, function, and nuclear localization in calreticulin-deficient cells.
The tumor suppressor protein, p53 is a transcription factor that not only activates expression of genes containing the p53 binding site but also can repress the expression of some genes lacking this binding site. Previous studies have shown that overexpression of wild-type p53 leads to apoptosis and cell cycle arrest. DNA damage, such as that caused by UV irradiation, results in p53 stabilizati...
متن کاملp53 genes function to restrain mobile elements.
Throughout the animal kingdom, p53 genes govern stress response networks by specifying adaptive transcriptional responses. The human member of this gene family is mutated in most cancers, but precisely how p53 functions to mediate tumor suppression is not well understood. Using Drosophila and zebrafish models, we show that p53 restricts retrotransposon activity and genetically interacts with co...
