Abstract

Background

Polycystic ovarian syndrome (PCOS), a gynae-endocrine disorder, has a relatively high risk of differential expression of miRNA (DE-miRNA) in the disease progression.

Aims

To identify the DE-miRNA in the progression of PCOS in the ovarian cumulus cells.

Methods

The microarray dataset GSE72274 was analysed for PCOS-associated DE-miRNAs. miRNet identifies the target genes. Protein–protein interaction (PPI) network was constructed and hub genes were analysed by topology and module analysis. Transcription factors (TFs) and protein kinases (PKs) regulating the hub genes were identified using X2K tool. Biological functions were analysed using DAVID software. Finally, the DGIdb drug-gene interaction tool identifies the candidate medications.

Results

A total of 1577 DE-miRNAs linked to PCOS were identified, with 13 meeting the specified criteria. Subsequently, its 2053 target genes were retrieved through miRNet. Topology and module analysis identified the hub genes VEGFA, SOX2, KRAS, AKT1, and SMAD4 that are implicated in ovarian regulation. Notably, the study highlighted the significant role of the wnt signalling pathway, which is involved in ovarian function, specifically in follicle development, corpus luteum formation, and steroid production. Additionally, six TFs and PKs were identified as important regulators of these hub genes, and the potential medication interactions identified 11 medicines for VEGFA, KRAS, AKT1, and SMAD4 genes, while no suitable drug for SOX2 was identified.

Conclusion

Identified, hub genes are known to associate with the regulation of ovarian function such as oocyte development, and steroid synthesis via the wnt signalling pathway.

Verbände und Cremes gegen Dekubitus: „Wir wissen nicht, was sie bringen!“

Die Datenlage zur Wirksamkeit von Verbänden oder topischen Mitteln zur Prävention von Druckgeschwüren sei schlecht, so die Verfasser einer aktuellen Cochrane-Studie. Letztlich bleibe es unsicher, ob solche Maßnahmen den Betroffenen nutzen oder schaden.

Schützt das tägliche Glas Milch vor Darmkrebs?

Die Milch machts – sie bietet Frauen nach Daten einer großen Ernährungsanalyse den besten Darmkrebsschutz aller Lebensmittel, was am hohen Kalziumgehalt liegen dürfte. Am anderen Ende des Spektrums steht der Alkoholkonsum: Das Glas Wein am Abend ist eher ungünstig.

Vorsicht mit Glukokortikoiden bei Glomerulopathie

Auch niedrig dosierte Glukokortikoide zur Behandlung einer primären Glomerulopathie lassen offenbar die Infektionsgefahr steigen. In einer US-Studie hing das Risiko vor allem mit der kombinierten Anwendung von Immunsuppressiva zusammen.

KI-gestütztes Mammografiescreening überzeugt im Praxistest

Mit dem Einsatz künstlicher Intelligenz lässt sich die Detektionsrate im Mammografiescreening offenbar deutlich steigern. Mehr unnötige Zusatzuntersuchungen sind laut der Studie aus Deutschland nicht zu befürchten.
