Bibliometric Analysis of Bronchopulmonary Dysplasia in Extremely Premature Infants in the Web of Science Database Using CiteSpace Software.

To review the literature related to bronchopulmonary dysplasia in extremely pre-mature infants, summarize research direction, and report trends. CiteSpace is a Java application which supports visual exploration with knowledge discovery in bibliographic databases. Relevant articles from 2008 to 2020 were retrieved from the Web of Science Core Collection database, and we extracted the following data: title, abstract, year, keywords, author, organization, journal and cited literature.

Inhibition of SUMO-specific protease 1 induces apoptosis of astroglioma cells by regulating NF-κB/Akt pathways.

SUMO-specific protease 1 (SENP1) is an important regulation protease in the protein desumoylation, which was shown to have a prooncogenicrole in many types of cancer. However, the mechanism of action for SENP1 in astrocytoma is not yet clear. Astrocytoma is the most frequent one among various neurogliomas, of which a subtype known as glioblastoma multiforme (GBM) is the most malignant brain glioma and seriously influences the life quality of the patients.

Cold-inducible RNA-binding protein inhibits neuron apoptosis through the suppression of mitochondrial apoptosis.

Cold-inducible RNA-binding protein (CIRP) is induced by mild hypothermia in several mammals, but the precise mechanism by which CIRP mediates hypothermia-induced neuroprotection remains unknown. We aimed to investigate the molecular mechanisms by which CIRP protects the nervous system during mild hypothermia. Rat cortical neurons were isolated and cultured in vitro under mild hypothermia (32°C).

Exogenous C-type natriuretic peptide infusion ameliorates unilateral ureteral obstruction-induced tubulointerstitial fibrosis in rats.

Although many experimental therapeutic roles for C-type natriuretic peptide (CNP) have been documented in the field of cardiovascular and pulmonary-vascular disease, the therapeutic uses of CNP to nephropathies are not as well documented. In this study, we established a rat model of unilateral ureteral obstruction (UUO) to observe the beneficial effects of CNP on tubulointerstitial fibrosis (TIF). In UUO rats, CNP administration induced a significant increase in plasma CNP levels, and caused a significant decrease in blood urea nitrogen and creatinine levels.

Paradoxical expressions of natriuretic peptide receptor-C and neutral endopeptidase account for C-type natriuretic peptide decline during the progression of experimental obstructive nephropathy.

Introduction: C-type natriuretic peptide (CNP) selectively binds to the guanylyl cyclase coupled natriuretic peptide receptor (NPR)-B and exerts more potent antihypertrophic and antifibrotic properties. Elimination of CNP occurs mainly by neutral endopeptidase (NEP) and NPR-C.

Methods: We established a rat model of unilateral ureteral obstruction (UUO) to examine the continuous change of the CNP expression and to assess the correlations of NPR-B, NPR-C, NEP with CNP in the obstructed kidneys.

Differential expression of the RNA-binding motif protein 3 in human astrocytoma.

Background: The RNA-binding motif protein 3 (RBM3), which is transcriptionally induced by low temperature and hypoxia, has recently been found to be upregulated in human tumors. However, its expression status in human astrocytoma is not well defned. This article focuses on the differential expression of RBM3 in human astrocytomas of different grades and normal brain tissues.

Targeting c-Myc on cell growth and vascular endothelial growth factor expression in IN500 glioblastoma cells.

Background: The level of c-Myc is closely associated with high pathological grade and the poor prognosis of gliomas. Vascular endothelial growth factor (VEGF) is the most important angiogenic factor that potently stimulates the proliferation and migration of vascular endothelial cells. This study aimed to address the biological importance of c-Myc in the development of gliomas, we downregulated the expression of c-Myc in the human glioblastoma cell line IN500 and studied the in vitro effect on cellular growth, proliferation, and apoptosis and the expression of VEGF and the in vivo effect on tumor formation in a xenograft mouse model.
