To determine whether this MMP-1 expression correlated with elevated mitogen-activated protein kinase, we analyzed these same human samples for p-ERK activity. Initial experiments were performed in the absence of the specific p42/p44 (ERK) substrate to determine endogenous protein phosphorylation in normal and emphysematous lungs. No difference was detected (Fig. 5A, left). However, when specific p-ERK activity was examined, significantly higher levels were detected in lung homogenates from patients with emphysema, compared with healthy control subjects (Fig. 5A, right: 1.9 ± 0.2-fold increase above normal lung, p = 0.02). We next assessed levels of ERK in eight human lung samples. Western blot analysis revealed that emphysematous lungs expressed higher p-ERK levels than normal lungs (Fig. 5B)."; prov:wasQuotedFrom pubmed:14764579 . sub:_6 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:14764579; prov:wasDerivedFrom beldoc:, sub:_5 . } sub:pubinfo { this: dct:created "2014-07-03T14:30:20.305+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
