Cussac, Daniel, Stéphane Schaak, Céline Gales, Christodoulos Flordellis, Colette Denis, and Hervé Paris. 2B-Adrenergic receptors activate MAPK and modulate proliferation of primary cultured proximal tubule cells. Am J Physiol Renal Physiol 282: F943–F952, 2002. First published August 8, 2001; 10.1152/ajprenal.0108.2001.—In the rat proximal tubule, the 2B-adrenergic receptor ( 2BAR) enhances Na ...

BACKGROUND: Canine parvovirus (CPV) infection is one ofthe most common causes of infectious gastroenteritis in dogs andis a highly contagious, often fatal disease. The original virus(CPV type 2) has had some mutations since its emergence andnew variants (CPV-2a, 2b and 2c) have been reported from manycountries all around the world. Early diagnosis and treatment canprofoundly affect the disease ...

The mammalian myocardium expresses four adenosine receptor (AR) subtypes: A(1)AR, A(2a)AR, A(2b)AR, and A(3)AR. The A(1)AR is well known for its profound antiadrenergic effects, but the roles of other AR subtypes in modulating contractility remain inconclusive. Thus, the objective of this study was to determine the direct and indirect effects of A(2a)AR and A(2b)AR on cardiac contractility. Exp...

The aminergic alpha(2b)-adrenergic receptor (alpha(2b)-AR) third intracellular loop (alpha(2b)-AR 3i) mediates receptor subcellular compartmentalization and signal transduction processes via ligand-dependent interaction with G(i)- and G(o)- proteins. To understand the structural origins of these processes we engineered several lengths of alpha(2b)-AR 3i into the third intracellular loop of the ...

The poliovirus nonstructural proteins 2B, 2C, 2C3A, 2C3AB, 3A, and 3AB have been cloned and efficiently expressed in Escherichia coli cells. Each individual protein, or combinations of some of them, were cloned using polymerase chain reaction techniques and correspond to the genuine poliovirus protein plus an additional methionine. The system used to express them uses pET vectors containing the...

OBJECTIVE To describe the phenotypic spectrum of dysferlin (DYSF) gene mutations (which cause dysferlinopathies, autosomal recessive muscular dystrophies) in patients with a dysferlin protein deficiency. DESIGN Clinical, biological, and pathological data from 40 patients were reviewed. The diagnosis of dysferlinopathy was based on the absence or strong reduction of dysferlin in muscle, and co...

A total of 26% of the pneumococci isolated from an outpatient clinic in Nairobi, Kenya, during 1991 to 1992 had intermediate levels of penicillin resistance. Gene fingerprinting and DNA sequencing were used to distinguish the penicillin-binding protein (PBP) 1A, 2B, and 2X genes in 23 resistant isolates. Isolates were grouped into those that had identical forms of each of the three PBP genes (f...

Exosomes from cancer cells, which contain microRNA and reach metastasis loci prior to cancer cells, stimulate the formation of a metastatic microenvironment. Previous studies have shown that exosomal miR-141-3p is associated with metastatic prostate cancer (PCa). However, the role and regulatory mechanism of miR-141-3p in the microenvironment of bone metastases require further study. In this st...
