Genetic deletion of Bax prevents mutant LRRK2 induced neuronal death. Primary embryonic cortical neurons are derived from WT mice or mice lacking the pro-apoptotic protein Bax, and transiently transfected with GFP-tagged WT or mutant LRRK2 (R1441C, G2019S). (a) A representative image showing typical morphological features of apoptotic neurons expressing mutant LRRK2; that are positive for active caspase-3 (casp3) and display condensed and fragmented nuclei. (b) Quantification of apoptotic neuronal death (apoptotic nuclear profiles, “apo”; and active caspase-3 positive neurons, “casp3”) from cultures depicted in (a); **p < 0.01 in comparison to WT transfected neurons. (c) Primary neurons were prepared from WT mice or mice deficient in Bax, and treated with the topoisomerase I inhibitor camptothecin (“cam”, 5 μM, 18 hr), or doxorubicin (“doxo”, 10 ng/ml, 36 hr). Cells were fixed and processed for apoptotic nuclear counts. (d) Primary cortical neurons were prepared from WT mice or mice deficient in Bax, and transiently transfected with WT, R1441C, or G2019S LRRK2. As before, the cultures were fixed and the percentage of LRRK2-positive neurons that displayed apoptotic nuclear features was determined. The absence of Bax significantly protected neurons from death induced by mutant LRRK2. ***p < 0.001 compared to WT neurons expressing R1441C- or G2019S-LRRK2. Each data point represents the mean +/− SEM from 3–4 independent transfections from a representative culture. Cultures were repeated at least 3 times with similar differences.

Effects of IGF-1 or/and PDGF-bb on IL-1 beta-induced NF-kappa B-dependent pro-inflammatory, pro-apoptotic and matrix degrading gene products in chondrocytes.To determine whether IGF-1 or/and PDGF-bbexert effects on IL-1 beta-induced NF-kappa B-dependent expression of pro-inflammatory, pro-apoptotic and matrix degrading gene products, primary chondrocytes were either stimulated with 10 ng/ml IL-1 beta, 10 ng/ml PDGF-bb, 10 ng/ml IGF-1 or combination of both growth factors (5 ng/ml each) or pre-stimulated for 12 h with 10 ng/ml PDGF-bb, 10 ng/ml IGF-1 or combination of both growth factors (5 ng/ml each) followed by 10 ng/ml IL-1 beta for 24. Equal amounts of total proteins were separated by SDS-PAGE and analyzed by immunoblotting using antibodies raised against COX-2, MMP-9 and MMP-13 and active caspase-3. Stimulation with IL-1 beta resulted in production of COX-2, MMP-9, MMP-13 and caspase-3 cleavage. Pre-treatment with a combination of both IGF-1 or/and PDGF-bb downregulated COX-2, MMP-9, MMP-13 and cleaved caspase-3.

Detection of Canine Human/Mouse Active Caspase-3 Antibody by Western Blot

Effects of IGF-1 or/and PDGF-bb on IL-1 beta-induced NF-kappa B-dependent pro-inflammatory, pro-apoptotic and matrix degrading gene products in chondrocytes.To determine whether IGF-1 or/and PDGF-bbexert effects on IL-1 beta-induced NF-kappa B-dependent expression of pro-inflammatory, pro-apoptotic and matrix degrading gene products, primary chondrocytes were either stimulated with 10 ng/ml IL-1 beta, 10 ng/ml PDGF-bb, 10 ng/ml IGF-1 or combination of both growth factors (5 ng/ml each) or pre-stimulated for 12 h with 10 ng/ml PDGF-bb, 10 ng/ml IGF-1 or combination of both growth factors (5 ng/ml each) followed by 10 ng/ml IL-1 beta for 24. Equal amounts of total proteins were separated by SDS-PAGE and analyzed by immunoblotting using antibodies raised against COX-2, MMP-9 and MMP-13 and active caspase-3. Stimulation with IL-1 beta resulted in production of COX-2, MMP-9, MMP-13 and caspase-3 cleavage. Pre-treatment with a combination of both IGF-1 or/and PDGF-bb downregulated COX-2, MMP-9, MMP-13 and cleaved caspase-3.

Detection of Caspase-3 by Western Blot

Allelic loss of Cdh11 led to faster growing tumors due to decreased cell death. (E) Cadherin-11 was knocked down using stealth siRNA in a cadherin-11 expressing cell line derived from TAg-RB tumors, T +539. Knockdown of Cdh11 clearly decreased caspase-3 expression compared to control.

Detection of Caspase-3 by Western Blot

Curcumin inhibits IL-1 beta activity, enabling co-culture induced chondrogenesis in MSCs. A: Fourteen days high-density culture. Untreated MSC cultures became apoptotic (a). In primary chondrocyte cultures (b), co-cultures (c), co-cultures treated with curcumin (e) or co-cultures pre-stimulated four hours with curcumin (f), prominent chondrogenesis was observed. Stimulation of the co-culture with IL-1 beta alone resulted in degeneration of the cell culture (d). In contrast, a four-hour pre-stimulation of the co-culture with curcumin followed by IL-1 beta incubation (g) or a four-hour pre-stimulation of the co-culture with curcumin followed by IL-1 beta and curcumin incubation (h) inhibited the adverse effects of IL-1 beta on the chondrogenic potential of the co-culture and prominent chondrogenesis was observed. Magnification, 6,000×; bar, 1 μm; C, chondrocytes, F, fibroblast-like cells; M, ECM. B-D: Immunoblots of whole cell lysates were probed with antibodies against CSPGs, collagen type II, beta1-integrin, Shc, activated-ERK1/2, Sox-9, activated-caspase-3 and COX-2. In co-cultures pre-stimulated for four hours with curcumin followed either by incubation with IL-1 beta alone or incubation with IL-1 beta and curcumin, prominent production of chondrogenic matrix and adhesion molecules (B), activation of the chondrogenic signalling pathway (C) and down-regulation of apoptotic and inflammatory markers (D) was observed. Each experiment was performed in triplicate. Expression of the housekeeping gene beta-actin was not affected.
