Improvement of polyhydroxybutyrate production by deletion of csrA in Escherichia coli

BACKGROUND: Poly-3-hydroxybutyrate (PHB) can be efficiently produced in recombinant Escherichia coli by the overexpression of an operon (NphaCAB) encoding PHB synthetase. Strain improvement is considered to be one of critical factors to lower the production cost of PHB in recombinant system. In this stud...

Prognostic value of increased expression of RBM8A in gastric cancer

Braz. j. med. biol. res; 53 (4), 2020
This study was designed to investigate the expression of RBM8A protein in patients with gastric cancer (GC) and to explore its correlation with clinical pathological features as well as prognosis. One hundred pairs of gastric carcinoma tissues and adjacent tissues from patients undergoing gastrectomy for...

Tumor suppressive function of Matrin 3 in the basal-like breast cancer

Biol. Res; 53 (), 2020
BACKGROUND: Basal-like breast cancer (BLBC) or triple-negative breast cancer (TNBC) is an aggressive and highly metastatic subtype of human breast cancer. The present study aimed to elucidate the potential tumor-suppressive function of MATR3, an abundant nuclear protein, in BLBC/TNBC, whose cancer-releva...

MicroRNA-1247 inhibits cell proliferation by directly targeting ZNF346 in childhood neuroblastoma

Biol. Res; 51 (), 2018
BACKGROUND: Neuroblastoma (NB) represents the most common extracranial solid tumor in children. Accumulating evidence shows that microRNAs (miRs) play an important role in the carcinogenesis of NB. Here, we investigated the biological function of miR-1247 in NB in vitro. METHODS/RESULTS: We found miR-12...

CIRBP protects H9C2 cells against myocardial ischemia through inhibition of NF-kappaB pathway

Braz. j. med. biol. res; 50 (4), 2017
Myocardial ischemia is a major cause of death and remains a disease with extremely deficient clinical therapies and a major problem worldwide. Cold inducible RNA-binding protein (CIRBP) is reported to be involved in multiple pathological processes, including myocardial ischemia. However, the molecular me...

Mutation analysis of NANOS3 in Brazilian women with primary ovarian failure

Clinics; 71 (12), 2016
OBJECTIVES: Primary ovarian failure is a rare disorder, and approximately 90% of cases are of unknown etiology. The aim of this study was to search for mutations in NANOS3, a gene that was recently related to the etiology of primary ovarian failure, in a group of Brazilian women. METHODS: We screened fo...

Knockdown of ZFR suppresses cell proliferation and invasion of human pancreatic cancer

Biol. Res; 49 (), 2016
BACKGROUND: Zinc finger RNA binding protein (ZFR) is involved in the regulation of growth and cancer development. However, little is known about ZFR function in pancreatic cancer. METHODS: Herein, to investigate whether ZFR is involved in tumor growth, Oncomine microarray data was firstly used to evaluat...
