[Effect of resveratrol on PTEN expression and fibrosis of renal tubular epithelial cells in a high-glucose environment].

This study explored the effects of resveratrol(Res) on the expression of phosphatase and tensin homolog deleted on chromosome ten(PTEN) and the fibrosis of rat renal tubular epithelial cells in a high-glucose environment and the possible mechanism underlying the fibrosis reduction. After the pretreatment of rat renal tubular epithelial cells(NRK-52 E) cultured in a high-glucose condition with Res or PTEN inhibitor SF1670, they were divided into several groups, i.e.

Poly[mu(8)-4,4'-bipyridine-2,2',6,6'-tetracarboxylato-dilead(II)].

The Pb(II) cation in the title compound, [Pb(2)(C(14)H(4)N(2)O(8))](n), is seven-coordinated by one N atom and six O atoms from four 4,4'-bipyridine-2,2',6,6'-tetracarboxylate (BPTCA(4-)) ligands. The geometric centre of the BPTCA(4-) anion lies on an inversion centre. Each pyridine-2,6-dicarboxylate moiety of the BPTCA(4-) ligand links four Pb(II) cations via its pyridyl N atom and two carboxylate groups to form two-dimensional sheets.
