RNA extraction from ten year old formalin-fixed paraffin-embedded breast cancer samples: a comparison of column purification and magnetic bead-based technologies (2007)

Ribeiro-Silva, Alfredo, Zhang, Haiyu, Jeffrey, Stefanie S

Abstract Background The development of protocols for RNA extraction from paraffin-embedded samples facilitates gene expression studies on archival samples with known clinical outcome. Older samples...

Inorganic polyphosphate in Dictyostelium discoideum: influence on development, sporulation, and predation. (2005)

Zhang, Haiyu, Gómez-García, M.R., Brown, M.R.W., Kornberg, A.

Dictyostelium discoideum, a social slime mold that forms fruiting bodies with spores, depends on inorganic polyphosphate (poly P) for its cycles of development and for nutritional predation on...

A polyphosphate kinase (PPK2) widely conserved in bacteria

Zhang, Haiyu, Ishige, Kazuya, Kornberg, Arthur

Synthesis of inorganic polyphosphate (poly P) from the terminal phosphate of ATP is catalyzed reversibly by poly P kinase (PPK, now designated PPK1) initially isolated from Escherichia coli. PPK1 is...

Polyphosphate kinase (PPK2), a potent, polyphosphate-driven generator of GTP

Ishige, Kazuya, Zhang, Haiyu, Kornberg, Arthur

An enzyme that uses inorganic polyphosphate (poly P) as a donor to convert GDP to GTP has been purified 1,300-fold to homogeneity from lysates of Pseudomonas aeruginosa PAOM5. Poly P chains of...

Inorganic polyphosphate in Dictyostelium discoideum: Influence on development, sporulation, and predation

Zhang, Haiyu, Gómez-García, María R., Brown, Michael R. W., Kornberg, Arthur

Dictyostelium discoideum, a social slime mold that forms fruiting bodies with spores, depends on inorganic polyphosphate (poly P) for its cycles of development and for nutritional predation on...

Inorganic polyphosphate in the social life of Myxococcus xanthus: Motility, development, and predation

Zhang, Haiyu, Rao, Narayan N., Shiba, Toshikazu, Kornberg, Arthur

Inorganic polyphosphate (poly P), a polymer of tens or hundreds of phosphate residues linked by high-energy, ATP-like bonds, is found in all organisms and performs a wide variety of functions....

Polyphosphate kinase 1, a conserved bacterial enzyme, in a eukaryote, Dictyostelium discoideum, with a role in cytokinesis

Zhang, Haiyu, Gómez-García, María R., Shi, Xiaobing, Rao, Narayana N., Kornberg, Arthur

Polyphosphate kinase 1 (PPK1), the principal enzyme responsible for reversible synthesis of polyphosphate (poly P) from the terminal phosphate of ATP, is highly conserved in bacteria and archaea....
