Figure 1Sequence and structural comparison of miR-E and miR-AB. The structures were predicted by CLC Main Workbench. The 22-bp sequences of passenger/sense (black) and guide/antisense (green) strands are highlighted in large font. The endogenous XhoI and EcoRI restriction sites used for miR-E cloning and the introduced BamHI and ApaI sites for miR-AB cloning are colored as indicated. The dashed rectangles indicate the sequences de novo generated by PCR or Gibson assembly for miR-E, or by oligo synthesis with desalt purification for miR-AB. miR-AB shRNAmir cloning strategy. A shRNAmir sequence obtained from SplashRNA or shERWOOD platform are converted to two oligos (75 bp and 67 bp respectively) by Microsoft Excel-based miR-AB Oligo Tool. These two oligos are synthesized, annealed and ligated to BamHI/ApaI-cut miR-AB viral vector for transfection into 293T cells to produce miR-AB virus. miR-AB cloning efficiency. Various amount of BamHI/ApaI-cut miR-AB vectors were ligated with miR-AB oligos (keep the ratio of vector mass to oligo mole at 1:1; for example, 1 ng of vector with 1 nmol of oligo) and colonies were counted after transformation of XL-10 Gold competent cells (homemade, 2 X 109 transformation efficiency).

Figure 1A. The localization of NSUN3 was analysed in HEK293 cells stably expressing NSUN3-GFP (green). NSUN3-GFP and staining with a Mitotracker (red) are shown separately and in an overlay with DAPI to indicate nuclei. The scale bar represents 5 m. B. To analyse submitochondrial localization of NSUN3, human mitochondria were isolated and either left untreated, swollen in hypotonic buffer (Mitoplasts) or solubilized by sonication (Sonic.) before treatment with different amounts of Proteinase K (PK) where indicated, followed by SDS-PAGE and Western blotting using antibodies against human TIM44, TIM23, TOM70 or FLAG-tagged NSUN3. Note that TIM44 localises to the matrix, while the N-terminus of TIM23 localises to the intermembrane space and TOM70 is largely exposed on the mitochondrial surface. The asterisk indicates a cross-reaction of the TOM70 antibody.

Relative expression of SHOX mRNA normalized to the reference genes SDHA and HPRT in human primary chondrocytes treated with ATRA 100 nM for 6h (n = 5). One outlier with high relative expression (2.3 fold) was excluded from ATRA 100 nM treatment (two-sided Grubb's test, Z value 2.34, p-value < 0.05). C. SHOX promoter was cloned in pGL3basic for luciferase reporter experiments as previously described (Verdin et al, 2015). In silico analysis of SHOX promoter identified three putative RXRa binding sites which were mutated to test their direct effect on SHOX expression upon treatment with ATRA 250 nM in U2OS cells (n = 4). Experiments were performed in triplicates. RLU, Relative Light Units. D. CYP26C1 and SHOX are members of the retinoic acid pathway. Vitamin A, retinol (ROL), enters the cell and is oxidized to retinaldehyde (RAL). RAL is then oxidized to retinoic acid (RA). RA can enter the nucleus and regulate the expression of its targets. CYP26C1 controls RA intracellular levels by oxidizing this molecule in more hydrosoluble retinoid molecules like 4'-hydroxy-retinoic acid (4'-OH-RA), which can be readily excreted. High levels of RA downregulate SHOX expression.

C Qualitative analysis of lung structure in Richardson-stained plastic-embedded lung sections from wild-type mouse pups at post-natal day (P) 14, treated with either scrambled antimiR (S), or antimiR-34a (A34a), during normal and aberrant alveolarization (scale bar, 50 µm).

G Quantitative analysis of PDGFRα+/αSMA+ cells by flow cytometry, in lungs from wild-type mouse pups at P5, treated with either scrambled antimiR (S), or antimiR-34a (A34a), during normal and aberrant alveolarization (n = 5 animals for each group). H Schematic illustration of the role and translational scope of the miR-34a/Pdgfra interaction during arrested lung alveolarization. Hyperoxia drives miR-34a expression in myofibroblasts, downregulating PDGFRα expression and reducing PDGFRα+ cell abundance, causing the perturbed elastin fiber production and blunted alveolarization seen in bronchopulmonary dysplasia (BPD). The effects of hyperoxia are attenuated when miR-34a function is blocked with an antimiR (A34a) or when the miR‑34a/Pdgfra interaction is disturbed with a target site blocker (TSB).

TLN lacks the characteristics of a γ-secretase substrate.Figure 2.(A) Western blot analysis of endogenous TLN and APP in wild-type and PS1−/− hippocampal neurons. PS1 deficiency results in the accumulation of APP-CTF. No TLN-CTF (estimated ± 7 kD) was detected, neither was it detected after SFV-induced exogenous overexpression. Also, overexpression of a TLNΔE fragment did not generate a PS1-dependent TLN intracellular domain. (B) Different constructs fused to the Gal4VP16 domain were used in a γ-secretase reporter assay. Control transfections (pIPspAdApt empty vector and pIPspAdApt-APP without Gal4VP16) show no luciferase activity. APP-Gal4VP16 and NotchΔE-Gal4VP16 activate the luciferase gene upon cleavage and are inhibited by DAPT, L658,458, or compound 32 (125 nM). No luciferase activity was detected using TLNΔE or APP in which the transmembrane domain was replaced by that of TLN (APP/TLNTMR chimaera), indicating that this region is not cleaved by γ-secretase. (C) Left: γ-secretase inhibitors do not induce the formation of TLN accumulations. Wild-type hippocampal neurons were treated with γ-secretase inhibitors (125 nM, daily from d 7-14 post-plating), fixed, and immunostained for TLN and the percentage of neurons with TLN accumulations was scored. Culturing neurons for 25 d increases the size and number (insets), but not the frequency of TLN accumulations (mean ± SEM, n = 3, 200-700 neurons per time point). Right: Western blot showing that only APP-CTF accumulates after chronic treatment with γ-secretase inhibitors. (D) Adenoviral reintroduction of human PS1 suppresses TLN accumulations. 30-35% of PS1−/− neurons display TLN accumulations, in contrast to <5% in PS1+/+ and +/− cultures as well as in cultures expressing human PS1 in a PS1−/− background. However, suppression of TLN accumulations was obtained by adenoviral introduction of human PS1. A clear dose-dependent inhibition was seen with increasing MOI of adenoviral (AV) human PS1, but also the familial Alzheimer's disease-linked PS1G384A and dominant-negative PS1D257A mutants. Control adenoviral infections with eGFP did not have a significant effect. After 9-11 d post-infection (15 d post-plating), neurons displayed significant PS1 protein expression as demonstrated by double staining for TLN and human PS1(mAb 5.2). Bars, 20 μm.

Differences were also statistically significant in HEL cells transfected with either JAK2V617F or JAK2L611V/V617F by comparison to controls (p = 0.0159 and p = 0.0009, respectively). The mature:immature ratio is also significantly higher in cells transfected with JAK2WT than in cells transfected with JAK2V617F or JAK2L611V/V617F (p < 0.01).

Figure 7In Sorafenib-sensitive cells, YAP/TAZ and ATF4 are not activated and not localized to the nucleus. As a consequence, the expression of anti-oxidant genes, such as SLC7A11, is not induced, and glutathione (GSH) levels are low. ROS levels then increase and ferroptosis can ensue, even more so in the presence of Sorafenib. In Sorafenib-resistant cell, YAP/TAZ and ATF4 are activated in the nucleus and induce the expression of SLC7A11 which increases GSH levels. ROS levels are thus reduced, ferroptosis is repressed, and HCC cells survive even in the presence of Sorafenib.
