Staurosporine-induced apoptosis of immortalized mouse proximal tubule cells is modulated by bcl-2 expression level.

Biochemistry and molecular biology international

Takeda M, Kobayashi M, Osaki T, Shirato I, Endou H.
PMID: 19856280
Biochem Mol Biol Int. 1997 Jul;42(4):649-56. doi: 10.1080/15216549700203061.

Mouse terminal proximal tubule (S3)cells treated with staurosporine (STS) underwent morphological and biochemical changes characteristic of apoptosis. Treatment of S3 cells with STS, H-7, PMA, herbimycin A or genistein caused DNA fragmentation. STS inhibited the activity of protein kinase...

Biochem Mol Biol Int. 1997 Jul;42(4):711-6. doi: 10.1080/15216549700203131.

In order to identify functional residues of the bacteriophage SP6 RNA polymerase, its C-terminal one-twelfth region was randomly mutagenized using polymerase chain reactions of its gene under the conditions for reduced fidelity of Taq DNA polymerase. Using a two-vector...

The priming effects of some human interleukins on the production of leukotrienes by calcium ionophore stimulated leukocytes.

Biochem Mol Biol Int. 1997 Jul;42(4):817-24. doi: 10.1080/15216549700203251.

This study demonstrates the changing levels of leukotrieneB4 (LTB4) and leukotrieneC4 (LTC4) generated by human white blood cells primed with different human interleukins IL-3, IL-5, IL-6, IL-8 and with human hematopoietic growth factor granulocyte-macrophage colony stimulating factor (GM-CSF). Preincubation...

Efficient production of active TNF-alpha by albumin signal peptide.

Biochemistry and molecular biology international

Maeda Y, Soda M, Ito K, Sato K.
PMID: 19856300
Biochem Mol Biol Int. 1997 Jul;42(4):825-32. doi: 10.1080/15216549700203261.

TNF-alpha is initially synthesized as a membrane-anchored precursor protein and processed proteolytically by a matrix metalloproteinase (MMP)-like enzyme. In order to establish an efficient expression system of TNF-alpha in mammalian cells without involvement of the extracellular enzyme, an expression...

Expression or possession of catalase gene does not alter the capacity of M. smegmatis to survive within human macrophages.

Biochemistry and molecular biology international

Fazal N.
PMID: 19856302
Biochem Mol Biol Int. 1997 Jul;42(4):843-51. doi: 10.1080/15216549700203281.

Mycobacterium tuberculosis genes are expressed and screened in Mycobacterium smegmatis as a host, hence their survival in human monocytes needs to be determined. Strains of Mycobacterium smegmatis with an inactive catalase-peroxidase gene (KatG), or into which the KatG gene...

Cytotoxic activity of acetylcholine receptor ligands.

Biochemistry and molecular biology international

Blishchenko EY, Mirkina II, Mernenko OA, Yatskin ON, Satpaev DK, Strizhkov BN, Karelin AA.
PMID: 19856291
Biochem Mol Biol Int. 1997 Jul;42(4):739-47. doi: 10.1080/15216549700203171.

Acetylcholine receptor ligands were studied for cytotoxicity in K562 human erythroid leukemia tumor cells. Cytotoxicity of carbachol, an agonist of acetylcholine receptors, atropine, an antagonist of muscarinic acetylcholine receptor, neurotoxin 11 (NT II) from Naja naja oxiana cobra venom...

Protoporphyrin IX potentiates horseradish peroxidase-catalyzed oxidation of NADH:Involvement of enzyme-porphyrin interaction.

Biochemistry and molecular biology international

Sil S, Chakraborti AS.
PMID: 19856293
Biochem Mol Biol Int. 1997 Jul;42(4):759-68. doi: 10.1080/15216549700203191.

Protoporphyrin IX potentiates horseradish peroxidase-catalyzed hydrogen peroxide-mediated NADH oxidation, but the porphyrin cannot change the enzyme-catalyzed o-dianisidine oxidation. Spectrofluorimetric studies reveal that an interaction occurs between horseradish peroxidase and protoporphyrin IX. The interaction is predominantly hydrophobic and entropy-driven endothermic...

The activity of branched-chain alpha-keto acid dehydrogenase complex in rat digestive tracts: Effects of dietary protein and exercise.
