Three new shuttle vectors for heterologous expression in Zymomonas mobilis

Electron. j. biotechnol; 19 (1), 2016
Background: Zymomonas mobilis, as a novel platform for bio-ethanol production, has been attracted more attention and it is very important to construct vectors for the efficient expression of foreign genes in this bacterium. Results: Three shuttle vectors ( pSUZM 1, pSUZM2 and pSUZM3 ) were first construc...

Implantation of muscle satellite cells overexpressing myogenin improves denervated muscle atrophy in rats

Braz. j. med. biol. res; 49 (2), 2016
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgi...

Sox2 function as a negative regulator to control HAMP expression

Biol. Res; 48 (), 2015
BACKGROUND: Hepcidin, encoding by HAMP gene, is the pivotal regulator of iron metabolism, controlling the systemic absorption and transportation of irons from intracellular stores. Abnormal levels of HAMP expression alter plasma iron parameters and lead to iron metabolism disorders. Therefore,itis animpo...

Presença de marcadores de células-tronco em linhagens celulares humanas de câncer de mama: possível valor em diagnóstico, prognóstico e terapía

O câncer de mama é a doença maligna que mais acomete as mulheres no mundo. Apesar dos inúmeros tratamentos, o óbito se deve principalmente à doença metastática que pode se desenvolver a partir do tumor primário. Esta progressão tumoral decorre da dificuldade de se estabelecer um prognóstico ma...

Identificação de adesinas de Leptospira interrogans por shotgun phage display

Em Leptospira interrogans algumas proteínas com capacidade de ligação aos componentes de matriz extracelular foram identificadas e, em sua maioria, são fatores de virulência. Phage display é considerada uma técnica poderosa na identificação de novos ligantes, inclusive de moléculas adesinas, im...

Detección de Chlamydia trachomatis en muestras de exudado endocervical por la reacción en cadena de la polimerasa
Detection of Chlamydia trachomatis in samples of endocervical exudate by polymerase chain reaction

Rev. cuba. endocrinol; 13 (2), 2002
Se procesaron 59 muestras de exudado endocervical, de mujeres que asistieron a 2 clínicas de infertilidad y a consulta de regulación menstrual de Ciudad de La Habana, para evaluar el desempeño de un método de detección de Chlamydia trachomatis, basado en la reacción en cadena de la polimerasa (PCR)...

Construction of a cassette for cloning and analysis of replicons

Acta cient. venez; 51 (1), 2000
The aim of this work was the construction of a cassette, i.e., a non-replicative molecule formed by linkage of an antibiotic resistance gene and a multiple cloning site. This cassette would allow the cloning and analysis of a wide range of replicons. The aac(6')-lc amikacin gene was isolated and ligated ...
