Figure Lengend Snippet: BMM (treated with siRNA to either CLIMP-63 or RTN4 or treated with control siRNA, Ctr) were infected with L. donovani or L. amazonensis metacyclic promastigotes and at various time points post-phagocytosis parasite replication and PV size were assessed. (A) Quantification of L. donovani parasite burden in CLIMP-63 depleted BMM at 6, 24, 48, and 72 h post-infection. (B) Quantification of L. amazonensis parasite burden in CLIMP-63 depleted BMM at 6, 24, 48, and 72 h post-infection. (C) Quantification of PV size in CLIMP-63-depleted BMM infected with L. amazonensis at 48 and 72 h post-phagocytosis. (D) Quantification of L. donovani parasite burden in RTN4-depleted BMM at 6, 24, 48, and 72 h post-infection. (E) Quantification of L. amazonensis parasite burden in RTN4-depleted BMM at 6, 24, 48, and 72 h post-infection. (F) Quantification of PV size in RTN4-depleted BMM infected with L. amazonensis at 48 and 72 h post-phagocytosis. Data in (A, B, D, E) are presented as the means ± SEM of values of one representative experiment of three independent experiments. Data in (C, F) are presented as a violin plot with means ± standard deviations (SD) of values from three independent experiments for a total of 450 PVs. Statistics were calculated using one-way analyses of variance (ANOVA) with Sidak’s multiple comparison test with * P ≤ 0.05, *** P ≤ 0.001 and **** P ≤ 0.0001 significance. Blots showing the efficacy the siRNA-mediated CLIMP-63 and RTN4 knockdowns are shown in S3 Fig and S4 Fig, respectively.

Article Title: TBC1D24 regulates mitochondria and endoplasmic reticulum-mitochondria contact sites

doi: 10.1101/2024.09.19.613961

Figure Lengend Snippet: (A-B) Representative images showing the localisation of Flag-TBC1D24 (Flag, Green) in transfected primary fibroblasts, along with mitochondria (TOM20, Magenta)(A) or ER tubules (RTN4, Magenta)(B). (C-D) TBC1D24 mutations affect the structure of ER tubules. (C) Representative images ER tubules (RTN4, Red) and nuclei (Dapi, Blue) in control and patient fibroblasts. Scale bars 10 µm (D) Quantification of ER tubule phenotypes from images in (C). Cells with ER tubules similar to the patient fibroblast shown in (C) were considered as altered. Each point represents an individual experiment. Bars show the average ± SD. *** P<0.001. One-way ANOVA. (E-F) TBC1D24 mutations affect the structure of ER sheets. (E) Representative images ER tubules (CLIMP63, Red) and nuclei (Dapi, Blue) in control and patient fibroblasts. Scale bars 10 µm (F) Quantification of ER sheets phenotypes from images in (E). Cells with ER tubules similar to the patient fibroblasts shown in (E) were considered as altered. Each point represents an individual experiment. Bars show the average ± SD. * p<0.05, *** P<0.001. One-way ANOVA.

Article Snippet: The cells were then incubated for 1 hour at room temperature in blocking buffer with the following primary antibodies: TOM20 (Rb, Abcam, ab186735, 1:250), CLIM63 (Mo, ENZO, ENZ-ABS669, 1: 200), RTN4 (Rb, Bio-Rad, AHP1799, 1:200), FLAG M2 (Mo, Sigma-Aldrich, F1804, 1:200).
