Overexpression and Characterization of The C-Terminal Domain of Human Siva1, A Proapoptotic Factor and Cytoskeleton Binding Protein.

Siva1 protein interacts with tumor protein p53 and with the member of the tumor necrosis factor receptor superfamily, stathmin, among others. These proteins are related to several pathways involved in cancer and are therefore strong candidate targets for drug design. This study aimed to characterize the biophysical properties of Siva 1 C- terminal domain to contribute to the discovery of new target directed drugs.

Pyrimidine-5'-nucleotidase Campinas, a new mutation (p.R56G) in the NT5C3 gene associated with pyrimidine-5'-nucleotidase type I deficiency and influence of Gilbert's Syndrome on clinical expression.

Pyrimidine-5'-nucleotidase type I (P5'NI) deficiency is an autosomal recessive condition that causes nonspherocytic hemolytic anemia, characterized by marked basophilic stippling and pyrimidine nucleotide accumulation in erythrocytes. We herein present two African descendant patients, father and daughter, with P5'N deficiency, both born from first cousins. Investigation of the promoter polymorphism of the uridine diphospho glucuronosyl transferase 1A (UGT1A) gene revealed that the father was homozygous for the allele (TA7) and the daughter heterozygous (TA6/TA7).
