Article Title: Mesothelioma-Associated Fibroblasts Modulate the Response of Mesothelioma Patient-Derived Organoids to Chemotherapy via Interleukin-6

doi: 10.3390/ijms25105355

Figure Lengend Snippet: IL-6 was increased in the medium of mPDO + MAF co-cultures after C+P challenge and mediated increased OFA. ( A ) A Luminex-based assay for eight cytokines was used to detect inflammatory chemokines in the conditioned media of mPDO+MAF co-cultures. The histogram shows the average levels of the indicated cytokines from two independent experiments. ( B ) IL-6 is mainly secreted by MAFs after C+P. mPDOs, MAFs, and co-cultured mPDO+MAFs were assayed for IL-6 secretion 24 h after the C+P challenge by indirect ELISA. Results are expressed as fold-over controls, where controls are ctrl (vehicle)-treated cells. ( C ) Increased IL-6 may mediate the resistance of mPDOs to C+P. Y axis: OFA score (number of organoids formed/1000 live cells) was calculated in mPDO cultures challenged with ctrl (MAF-CM, not treated with C+P) or with MAF-CM (treated with C+P), in the presence of anti-IL-6 neutralising antibody (IL-6-IgG) or a control antibody (ctrl-IgG). Histograms represent the mean + SE of three independent experiments. Statistics: ** p < 0.01; ns = not significant.

Article Title: Protein kinase C epsilon-mediated modulation of T-type calcium channels underlies alcohol withdrawal hyperexcitability in the midline thalamus

doi: 10.1111/acer.15342

Figure Lengend Snippet: PKC mediates a T channel gain of function during alcohol withdrawal. (A–C) Representative traces of T-type current inactivation curves for (A) Air, (B) WD, and (C) WD + PKC (−) groups, respectively, elicited at −50 mV from holding potentials ranging from −135 to −60 mV for 1 s (inset). (D, E) Alcohol WD produced a significant depolarizing shift in the inactivation curve of native T-type calcium current. The depolarizing shift was blocked by PKC peptide inhibitors, including PKC epsilon-specific inhibitors. (F) V 50 derived from the inactivation curve ~5 h. into the 4th alcohol WD in C57BL/6 mice was analyzed. The significant depolarizing shift for V 50 was blocked by the PKC peptide inhibitor (PKC (−), 10 μM). This inhibition was mimicked by specific PKCε isoform inhibitors (#530993, 539522; 5 μM) but not a PKCε translocation inhibitor inactive peptide (#539542; 5 μM). All drugs were delivered through the internal pipette solution. Statistics for V 50 showed F (6, 73) = 3.87, p = 0.0021 (One-Way ANOVA). In the plot * indicates p <0.05 and ** indicates p <0.01.

Figure Lengend Snippet: Kinetic changes of T-channel during the application of PKC inhibitors recorded from the reuniens after 5 h into 4th alcohol withdrawal. (A, B) PKCε inhibitor (#530993, 5 μM) was applied through the bath solution, it significantly reduced rise time (A. paired t test, p = 0.0311, n = 6); increased rise slope (B. paired t test, p = 0.0266, n = 6); (C) Rise time did not show a significant main effect [ F (4, 53) = 2.205, p = 0.0809], although Dunnett’s post hoc test showed a significant difference between WD and WD plus PKCε (−), (#529522, p = 0.0223.* p <0.05). All drugs were delivered through the patch pipette internal solution, including the PKC peptide inhibitor (10 μM), and PKCε inhibitors (#530993, 5 μM; #539522, 5 μM).

Figure Lengend Snippet: Midline thalamic neurons exhibit more spikes per low-threshold Ca 2+ burst during alcohol withdrawal. PKCε translocation inhibitor peptide (#539522) reduced the number of spikes/burst after 4th WD.

doi: 10.1111/acer.15342

Figure Lengend Snippet: T-current-mediated bursting was elicited near resting membrane potential from a series of hyperpolarizing prepulse current injections. Using a procedure analogous to the voltage clamp inactivation protocol (current injections started from 0 to −400 pA, −50 pA step, 500 ms of duration), we measured T-current-mediated bursting. Control (A) and air-exposed (B) conditions elicit 1–3 action potentials/burst. After the 4th WD (C), the cells responded with increased numbers of spikes/burst, which were reduced by the PKC ε inhibitor (D) but not the PKC ε inhibitor inactive peptide (E).
