Abstract

Smads are the key intermediates of canonical transforming growth factor-beta (TGF-β) signaling. These intermediates are divided into three distinct subgroups based on their role in TGF-β family signal transduction: Receptor-regulated Smads (R-Smads) 1, 2, 3, 5 and 8, common Smad4, and inhibitory Smads6 and 7. TGF-β signaling through Smad pathway involves phosphorylation, ubiquitination, sumoylation, acetylation, and protein–protein interactions with mitogen-activated protein kinases, PI3K-Akt/PKB, and Wnt/GSK-3. Several studies have suggested that upregulation or downregulation of TGF-β/Smad signaling pathways may be a pathogenic mechanism in the progression of chronic kidney disease. Smad2 and 3 are the two major downstream R-Smads in TGF-β-mediated renal fibrosis, while Smad7 also controls renal inflammation. In this review, we characterize the role of Smads in kidney disease, describe the molecular mechanisms, and discuss the potential of Smads as a therapeutic target in chronic kidney disease.

Notfall-TEP der Hüfte ist auch bei 90-Jährigen machbar

26.04.2024 Hüft-TEP Nachrichten

Ob bei einer Notfalloperation nach Schenkelhalsfraktur eine Hemiarthroplastik oder eine totale Endoprothese (TEP) eingebaut wird, sollte nicht allein vom Alter der Patientinnen und Patienten abhängen. Auch über 90-Jährige können von der TEP profitieren.

Niedriger diastolischer Blutdruck erhöht Risiko für schwere kardiovaskuläre Komplikationen

25.04.2024 Hypotonie Nachrichten

Wenn unter einer medikamentösen Hochdrucktherapie der diastolische Blutdruck in den Keller geht, steigt das Risiko für schwere kardiovaskuläre Ereignisse: Darauf deutet eine Sekundäranalyse der SPRINT-Studie hin.

Bei schweren Reaktionen auf Insektenstiche empfiehlt sich eine spezifische Immuntherapie

Insektenstiche sind bei Erwachsenen die häufigsten Auslöser einer Anaphylaxie. Einen wirksamen Schutz vor schweren anaphylaktischen Reaktionen bietet die allergenspezifische Immuntherapie. Jedoch kommt sie noch viel zu selten zum Einsatz.

Therapiestart mit Blutdrucksenkern erhöht Frakturrisiko

25.04.2024 Hypertonie Nachrichten

Beginnen ältere Männer im Pflegeheim eine Antihypertensiva-Therapie, dann ist die Frakturrate in den folgenden 30 Tagen mehr als verdoppelt. Besonders häufig stürzen Demenzkranke und Männer, die erstmals Blutdrucksenker nehmen. Dafür spricht eine Analyse unter US-Veteranen.
