Testosterona inhibe la actividad de la aldosterona sintasa silvestre y quimérica in vitro

Rev. méd. Chile; 149 (11), 2021
BACKGROUND: Familial hyperaldosteronism type I is caused by the generation of a chimeric aldosterone synthase enzyme (ASCE) which is regulated by ACTH instead of angiotensin II. We have reported that in vitro, the wild-type (ASWT) and chimeric aldosterone synthase (ASCE) enzymes are inhibited by progeste...

Serum-Free Suspension Adaptation of HEK-293T Cells: Basis for Large-Scale Biopharmaceutical Production

Abstract Human Embryonic Kidney 293T cells (HEK-293T) are the most common host for viral vector production and are also widely employed for recombinant protein production. These cells are typically cultured in monolayer (adherent culture) using culture medium containing fetal bovine serum (FBS), which im...

Assessment of Antioxidant and Cytotoxic Activities and Identification of Phenolic Compounds of Centaurea solstitialis and Urospermum picroides from Turkey

HIGHLIGHTS The phenolic composition, antioxidant activity and cytotoxic potential of the extracts of C. solstitialis and U. picroides were investigated. Caffeic acid was found as the most abundant phenolic compound in the extracts. Both species showed promising antioxidant activity towards different...

Overexpression of bHLH domain of HIF-1 failed to inhibit the HIF-1 transcriptional activity in hypoxia

Biol. Res; 53 (), 2020
BACKGROUND: Hypoxia inducible factor-1 (HIF-1) is considered as the most activated transcriptional factor in response to low oxygen level or hypoxia. HIF-1 binds the hypoxia response element (HRE) sequence in the promoter of different genes, mainly through the bHLH domain and activates the transcription ...

Development and characterization of a packaging cell line for pseudo-infectious yellow fever virus particle generation

Abstract INTRODUCTION: Pseudo-infectious yellow fever viral particles (YFV-PIVs) have been used to study vaccines and viral packaging. Here, we report the development of a packaging cell line, which expresses the YFV prM/E proteins. METHODS: HEK293 cells were transfected with YFV prM/E and C (84 nt) ...

Oridonin induces growth inhibition and apoptosis in human gastric carcinoma cells by enhancement of p53 expression and function

Braz. j. med. biol. res; 51 (12), 2018
The tumor suppressive role of oridonin, an active compound extracted from Rabdosia rubescens, has been proven in several gastric cancer (GC) cell lines. The present study aimed to evaluate the effect of oridonin on another GC cell line, SNU-216, and explore the potential mechanisms. The viable cell numbe...

Establishment of a HEK293T cell line able to site-specifically integrate and stably express GDNF by rAAV-2 vector

Electron. j. biotechnol; 19 (4), 2016
Background: Using recombinant adeno-associated virus 2 (rAAV-2), we attempted to establish a HEK293T cell line that is able to site-specifically integrate and stably express glial cell line-derived neurotrophic factor (GDNF). Results:Recombinant vector with enhanced green fluorescent protein (EGFP) and G...

Efeito dual de FGF2 e PMA em células HEK 293 transformadas por H-rasV12

Sabe-se há décadas que mutações nos genes ras estão presentes em cerca de 20% dos cânceres humanos, mas o desenvolvimento de terapias eficazes para o tratamento de câncer dependente dos oncogenes ras permanece um desafio científico importante. Nesse contexto, o nosso grupo publicou recentemente r...
