TGF-β Signaling Pathways in Different Compartments of the Lower Airways of Patients With Stable COPD

2017

Background: The expression and localization of transforming growth factor-β (TGF-β) pathway proteins in different compartments of the lower airways of patients with stable COPD is unclear. We aimed to determine TGF-β pathway protein expression in patients with stable COPD. Methods: The expression and localization of TGF-β pathway components was measured in the bronchial mucosa and peripheral lungs of patients with stable COPD (n = 44), control smokers with normal lung function (n = 24), and control nonsmoking subjects (n = 11) using immunohistochemical analysis. Results: TGF-β1, TGF-β3, and connective tissue growth factor expression were significantly decreased in the bronchiolar epithelium…

Age-dependent regulation of antioxidant genes by p38α MAPK in the liver

2018

p38α is a redox sensitive MAPK activated by pro-inflammatory cytokines and environmental, genotoxic and endoplasmic reticulum stresses. The aim of this work was to assess whether p38α controls the antioxidant defense in the liver, and if so, to elucidate the mechanism(s) involved and the age-related changes. For this purpose, we used liver-specific p38α-deficient mice at two different ages: young-mice (4 months-old) and old-mice (24 months-old). The liver of young p38α knock-out mice exhibited a decrease in GSH levels and an increase in GSSG/GSH ratio and malondialdehyde levels. However, old mice deficient in p38α had higher hepatic GSH levels and lower GSSG/GSH ratio than young p38α knock-…

Recovery of zinc from spent pickling solutions by liquid–liquid extraction using TBP

2019

In this paper, recovery of zinc from real spent pickling solutions by liquid–liquid extraction with tributyl phosphate (TBP) was studied. In particular, the effects of some parameters were investigated, such as the volume ratio between the organic phase and real spent pickling liquor (O/A) (1:2, 1:1, 2:1, 4:1), the stirring time (5–20–30 min) and the TBP concentration (10%–55%–100%), in order to determine the conditions leading to higher zinc extraction efficiency, as well as selectivity in relationships to other metals such as iron. After zinc extraction, TBP was successfully regenerated. Among several tested solutions, water allows zinc recovery higher than 90%, especially at 10% diluted …

A Regulatory Mechanism Involving TBP-1/Tat-Binding Protein 1 and Akt/PKB in the Control of Cell Proliferation

2011

Abstract TBP-1 /Tat-Binding Protein 1 (also named Rpt-5, S6a or PSMC3) is a multifunctional protein, originally identified as a regulator of HIV-1-Tat mediated transcription. It is an AAA-ATPase component of the 19S regulative subunit of the proteasome and, as other members of this protein family, fulfils different cellular functions including proteolysis and transcriptional regulation. We and others reported that over expression of TBP-1 diminishes cell proliferation in different cellular contexts with mechanisms yet to be defined. Accordingly, we demonstrated that TBP-1 binds to and stabilizes the p14ARF oncosuppressor increasing its anti-oncogenic functions. However, TBP-1 restrains cell…

Regulation of raft-derived endocytic pathways : studies on echovirus 1 and baculovirus

2009

Elina Kakkonen tutki väitöskirjassaan kahden erilaisen viruksen, echovirus 1:n ja bakuloviruksen soluun sisäänmenon reittejä ja säätelijöitä. Echovirus 1 (EV1) on ihmisiä infektoiva pikornavirus, joka voi aiheuttaa esimerkiksi aivokalvontulehdusta, sydänlihastulehdusta sekä lievempiä hengitystieinfektioita. Bakulovirus puolestaan on ihmisille vaaraton, hyönteisiä infektoiva virus, joka on osoittautunut lupaavaksi geeninsiirtokuljettajaksi geeniterapiassa.Virukset voivat käyttää soluun tunkeutumisessaan hyväkseen soluissa valmiina olevia erilaisia reittejä, joita solut itse tarvitsevat esimerkiksi ravintoaineiden sisäänottoon. Näin virukset pääsevät solun sisälle solun oman koneiston kuljett…
