Detection of Cellular Proteins and Viral Core Protein Interacting with the 5' Untranslated Region of Hepatitis C Virus RNA.

Journal of biomedical science

Hwang SB, Lo SY, Ou JH, Lai MM.
PMID: 11725058
J Biomed Sci. 1995 Aug;2(3):227-236. doi: 10.1007/BF02253382.

Hepatitis C virus (HCV) is a pesti- and flavi-like virus, which contains a highly conserved 5'-untranslated region (UTR). This region is implicated in the regulation of both translation and RNA replication. To examine the possible cellular factors involved in...

Long-term administering low anticoagulant activity heparin can lessen rat hepatic fibrosis induced by either CCl(4) or porcine serum injection.

Hepatology research : the official journal of the Japan Society of Hepatology

Li W, Zhang J, Huang Q, Zhu H, Zhang X.
PMID: 16904936
Hepatol Res. 2006 Oct;36(2):115-23. doi: 10.1016/j.hepres.2006.07.004. Epub 2006 Aug 14.

BACKGROUND/AIM: Heparin or heparin-derived molecules have been demonstrated to have a renoprotective activity in a number of experimental nephropathies and anti-fibrotic effect on pulmonary fibrosis induced by Bleomycin. However, the effectiveness of low anticoagulant activity heparin (LAAH) in the...

2,4-Dichlorophenoxyacetic Acid-enhanced Phosphorylation of Soybean Nuclear Proteins.

Plant physiology

Murray MG, Key JL.
PMID: 16660258
Plant Physiol. 1978 Feb;61(2):190-8. doi: 10.1104/pp.61.2.190.

In vitro nuclear protein phosphorylation is enhanced in nuclei isolated from 2,4-dichlorophenoxyacetic acid (2,4-d)-treated mature soybean (Glycine max) hypocotyl relative to nuclei from untreated tissue. Increased nuclear protein phosphorylation correlates with increased levels of nuclear protein kinase activity. These...

Initial function analysis of a novel erythroid differentiation related gene EDRF1.

Science in China. Series C, Life sciences

Wang D, Li Y, Shen B.
PMID: 18726394
Sci China C Life Sci. 2001 Oct;44(5):489-96. doi: 10.1007/BF02882391.

Erythroid differentiation depends on the establishment of specific patterns of gene expression. Hypersensitive site 2 (HS2, serving as a major enhancer of globin genes)-binding proteins may be involved in its natural open chromosomal environment formation. Previously we prepared monoclonal...

Flow-cytometric assessment of cellular poly(ADP-ribosyl)ation capacity in peripheral blood lymphocytes.

Immunity & ageing : I & A

Kunzmann A, Liu D, Annett K, Malaisé M, Thaa B, Hyland P, Barnett Y, Bürkle A.
PMID: 16854233
Immun Ageing. 2006 Jul 19;3:8. doi: 10.1186/1742-4933-3-8.

BACKGROUND: Poly(ADP-ribosyl)ation is a posttranslational modification of nuclear proteins catalysed by poly(ADP-ribose) polymerases (PARPs), using NAD+ as a substrate. Activation of PARP-1 is in immediate response to DNA damage generated by endogenous and exogenous damaging agents. It has been...

In silico analysis of the cyclophilin repertoire of apicomplexan parasites.

Parasites & vectors

Krücken J, Greif G, von Samson-Himmelstjerna G.
PMID: 19555495
Parasit Vectors. 2009 Jun 25;2(1):27. doi: 10.1186/1756-3305-2-27.

BACKGROUND: Cyclophilins (Cyps) are peptidyl cis/trans isomerases implicated in diverse processes such as protein folding, signal transduction, and RNA processing. They are also candidate drug targets, in particular for the immunosuppressant cyclosporine A. In addition, cyclosporine is known to...

A novel phosphoprotein analysis scheme for assessing changes in premalignant and malignant breast cell lines using 2D liquid separations, protein microarrays and tandem mass spectrometry.

Proteomics. Clinical applications

Patwa TH, Wang Y, Miller FR, Goodison S, Pennathur S, Barder TJ, Lubman DM.
PMID: 19194518
Proteomics Clin Appl. 2008;3(1):51-66. doi: 10.1002/prca.200800097.

An analysis of phosphorylation changes that occur during cancer progression would provide insights into the molecular pathways responsible for a malignant phenotype. In this study we employed a novel coupling of 2D-liquid separations and protein microarray technology to reveal...

Efficient method for generating nuclear fractions from marrow stromal cells.

Cytotechnology

Woodbury D, Len GW, Reynolds K, McAuliffe WG, Coyne T, Wu K.
PMID: 19052892

Stem cells have received significant attention for their envisioned potential to treat currently unapproachable diseases. No less important is the utility of stem cells to serve as model systems of differentiation. Analyses at the transcriptome, miRNA and proteome levels...

Rice bZIP protein, REB, interacts with GCN4 motif in promoter of Waxy gene.

Science in China. Series C, Life sciences

Cheng S, Wang Z, Hong M.
PMID: 18759022
Sci China C Life Sci. 2002 Aug;45(4):352-60. doi: 10.1360/02yc9039.

A bifactorial endosperm box (EB), which contains an endosperm motif (EM) and a GCN4 motif, was found in rice Wx promoter. EB was found in 5' upstream region of many seed storage protein genes accounting for these genes expression...
