Developmental Studies Hybridoma Bank cardiac troponin
(A) RT-PCR analysis of the expression of heart-specific isoforms of MHC, <t>troponin</t> <t>and</t> <t>tropomyosin;</t> and skeletal muscle-specific genes MyoD and muscle actin, throughout early and mid-tadpole stages of development in CMO (‘C’) and T5MO (‘T’) stage-matched embryos. All samples are derived from a single batch of eggs, and identical results were achieved in at least two independent sets of experiments for each marker. EF1-Alpha was used as a loading control for all RT-PCR reactions. (B–I) Images depicting embryos injected with (B–E) CMO, or (F–I) T5MO and immunostained for Tmy, showing delayed expression of Tmy in the hearts of T5MO embryos. Shown are representative sibling embryos imaged at the indicated stages. White arrows denote expression of Tmy within the heart. (J–Q) Images of living cardiac actin:GFP transgenic embryos, showing a delay in the onset of cardiac actin expression in the heart. Representative sibling embryos obtained from a single batch of embryos were injected with (J–M) CMO or (N–Q) T5MO and imaged at the indicated stages. Shown is a representative pair of embryos, while identical results were observed in over 50 embryos. White arrows denote expression of GFP within the heart field.

Developmental Studies Hybridoma Bank anti β tubulin antibody
(A–H) Visualization of active drICE with anti-cleaved caspase-3 antibody (CM1; green) and axonemal tubulin polyglycylation with anti-glycylated tubulin monoclonal antibody (AXO 49; red). These figures are composed of a green layer only in the left panel, and green and red layers combined in the right panel. (A) Wild-type individualizing spermatids stain positively for active effector caspase and polyglycylated axonemal tubulin (white arrows pointing at cystic bulges [CBs] and red arrow pointing at a waste bag [WB]). Elongated spermatids from (B) homozygotes for the null cul3 mds1 allele or (C and D) transheterozygotes for cul3 mds1 and two different deficiencies that cover the cullin-3 gene, DF (2L)ED3 and DF (2L)Exel8034, respectively, stain for polyglycylation but not for active effector caspase. (E–G) Homozygote mutants for three hypomorphic cul3 Testis alleles, cul3 mds5 , cul3 mds3 , and cul3 mds4 , respectively, have spermatid individualization defects but still display some levels of active effector caspase expression. (H) However, the level of active effector caspase expression was dramatically reduced in spermatids from transheterozygote mutants for the null cul3 mds1 and either of the hypomorphic alleles, such as cul3 mds4 . All the figures are in the same magnification; scale bar 200 μm. (I) The diagram depicts a DEVDase activity assay for cul3 mds1 −/− testes. Caspase-3–like (DEVDase) activity is detected in wild-type testes and is blocked either after treatment with the caspase-3 inhibitor Z-VAD.fmk or in cul3 mds1 −/− testes. DEVDase activity, presented as relative luminescence units (RLUs), was determined on Ac-DEVD-pNA substrate in testis extracts made of 180 wild-type ( yw ) or cul3 mds1 −/− testes treated with Z-VAD or left untreated (DMSO). Readings were obtained every 2 min, and each time interval represents an average (mean ± SEM) of five readings. Note that the level of DEVDase activity in cul3 mds1 −/− testes is highly similar to the corresponding level in wild-type testes that were treated with Z-VAD. (J) A Western blot analysis for the assessment of the relative protein amounts used in (I). A portion of the testis extracts in (I) were used as controls to determine the relative amounts of total protein in each extract using the anti- <t>β</t> <t>-Tubulin</t> antibody.

Cardiomyocyte structure in transverse sections through the hearts of (A,C,E,G) CMO or (B,D,F,H) T5MO stage 37 embryos, as detected by immunostaining for (A,B) cardiac troponin T (cTNT), (C,D) MHC, (E,F) actin or (G,H) Tmy. (I,K,M) Stage 37 CMO or (J,L,N) T5MO embryos double-immunostained for tropomyosin (green) and (I,J) fibronectin, (K,L) fibrillin or (M,N) β-catenin, all shown in red. Note increase in fibrillin staining on the walls of the chamber of T5MO hearts relative to CMO (compare panel K to L, white arrows) and ectoptic expression of fibronectin, shown by white arrow, in the dorsal portion of the heart in panel J relative to panel I. (O,P) High magnification confocal images of hearts from (O) CMO or (P) T5MO stage 37 embryos. Note that formation of organized cardiac muscle bundles in T5MO hearts is limited to a single cluster adjacent to the cardiac lumen. (Q–S) Representative transmission electron micrographs of transverse images of stage 37 embryos taken from (Q) CMO cardiac tissue or (R) T5MO cardiac tissue adjacent to the pericardial cavity and (S) T5MO cardiac tissue adjacent to the cardiac lumen. Cardiac muscle fibrils are shown pseudo-colored in yellow. Note that sarcomeres in T5MO hearts can only be identified adjacent to the cardiac lumen (compare R with S) and only found in concentric arrays. By contrast, CMO-derived hearts show both longitudinal and concentric arrays (compare Q with S). High-magnification TEM images reveal the ultrastructures of (T) CMO and (U) T5MO cardiac sarcomeres.

Figure Lengend Snippet: Cardiomyocyte structure in transverse sections through the hearts of (A,C,E,G) CMO or (B,D,F,H) T5MO stage 37 embryos, as detected by immunostaining for (A,B) cardiac troponin T (cTNT), (C,D) MHC, (E,F) actin or (G,H) Tmy. (I,K,M) Stage 37 CMO or (J,L,N) T5MO embryos double-immunostained for tropomyosin (green) and (I,J) fibronectin, (K,L) fibrillin or (M,N) β-catenin, all shown in red. Note increase in fibrillin staining on the walls of the chamber of T5MO hearts relative to CMO (compare panel K to L, white arrows) and ectoptic expression of fibronectin, shown by white arrow, in the dorsal portion of the heart in panel J relative to panel I. (O,P) High magnification confocal images of hearts from (O) CMO or (P) T5MO stage 37 embryos. Note that formation of organized cardiac muscle bundles in T5MO hearts is limited to a single cluster adjacent to the cardiac lumen. (Q–S) Representative transmission electron micrographs of transverse images of stage 37 embryos taken from (Q) CMO cardiac tissue or (R) T5MO cardiac tissue adjacent to the pericardial cavity and (S) T5MO cardiac tissue adjacent to the cardiac lumen. Cardiac muscle fibrils are shown pseudo-colored in yellow. Note that sarcomeres in T5MO hearts can only be identified adjacent to the cardiac lumen (compare R with S) and only found in concentric arrays. By contrast, CMO-derived hearts show both longitudinal and concentric arrays (compare Q with S). High-magnification TEM images reveal the ultrastructures of (T) CMO and (U) T5MO cardiac sarcomeres. Arrows denote A-bands. Note the smaller, non-continuous A-bands in the T5MO-derived sarcomeres (U). (V) Traces of the heart sections from CMO and T5MO embryos imaged by TEM are depicted schematically. Yellow circles represent the location of TEM imaging. Scale bars: 50 μm in A–N; 2 μm in Q–S; 0.2 μm in T,U.

The overall morphology of stage 40 (A) uninjected embryos or (B,C) embryos injected with increasing amounts of Tbx5 RNA, as indicated. Arrows denote the location of the heart. (D–G) Whole-mount in-situ hybridization showing expression of (D,E) Nkx2.5 and (F,G) myosin light chain (MLC) in (D,F) uninjected stage 37 embryos and (E,G) stage-matched embryos injected with 1 ng of Tbx5 RNA. (H) Tbx5 misexpression leads to an increase in the cardiac mitotic index at stage 37. Mitotic index was calculated as the percentage of cardiac cells labeled with pH3. The data represents the mean of at least three different embryos. Error bars denote the standard deviation, and * denotes a statistically significant difference between Tbx5-injected and control embryos (at P<0.05). (I) Mitotic index for sections of the neural tube corresponding to the same position as the heart along the anterior-posterior axis. The data represents the mean mitotic index of four different embryos per condition, with four sections analyzed per embryo. Error bars denote the standard deviation. (J) Tbx5 misexpression leads to an alteration in the timing and order of the cardiac differentiation program. RT-PCR analysis of the expression of Nkx2.5 as well as heart-specific isoforms of MHC, troponin and tropomyosin, and skeletal-muscle-specific genes, MyoD and muscle actin, throughout early and mid-gestation stages of development in control (‘C’) or Tbx5-injected (‘T’) stage-matched embryos. All samples are derived from a single batch of eggs and identical results were achieved in at least two independent sets of experiments for each marker. EF1-alpha was used as a control for all RT-PCR reactions.

These figures are composed of a green layer only in the left panel, and green and red layers combined in the right panel. (A) Wild-type individualizing spermatids stain positively for active effector caspase and polyglycylated axonemal tubulin (white arrows pointing at cystic bulges [CBs] and red arrow pointing at a waste bag [WB]). Elongated spermatids from (B) homozygotes for the null cul3 mds1 allele or (C and D) transheterozygotes for cul3 mds1 and two different deficiencies that cover the cullin-3 gene, DF (2L)ED3 and DF (2L)Exel8034, respectively, stain for polyglycylation but not for active effector caspase. (E–G) Homozygote mutants for three hypomorphic cul3 Testis alleles, cul3 mds5 , cul3 mds3 , and cul3 mds4 , respectively, have spermatid individualization defects but still display some levels of active effector caspase expression. (H) However, the level of active effector caspase expression was dramatically reduced in spermatids from transheterozygote mutants for the null cul3 mds1 and either of the hypomorphic alleles, such as cul3 mds4 . All the figures are in the same magnification; scale bar 200 μm. (I) The diagram depicts a DEVDase activity assay for cul3 mds1 −/− testes. Caspase-3–like (DEVDase) activity is detected in wild-type testes and is blocked either after treatment with the caspase-3 inhibitor Z-VAD.fmk or in cul3 mds1 −/− testes. DEVDase activity, presented as relative luminescence units (RLUs), was determined on Ac-DEVD-pNA substrate in testis extracts made of 180 wild-type ( yw ) or cul3 mds1 −/− testes treated with Z-VAD or left untreated (DMSO). Readings were obtained every 2 min, and each time interval represents an average (mean ± SEM) of five readings. Note that the level of DEVDase activity in cul3 mds1 −/− testes is highly similar to the corresponding level in wild-type testes that were treated with Z-VAD. (J) A Western blot analysis for the assessment of the relative protein amounts used in (I). A portion of the testis extracts in (I) were used as controls to determine the relative amounts of total protein in each extract using the anti- β -Tubulin antibody.

(A) Diap1 protein levels were not affected in cul3 mds1 and klhl10 3 mutant testes, as assessed by Western blotting of protein extracts from dissected testes. Therefore, Diap1 does not appear to be a major target for the Cul3-based E3-ligase complex. β - tubulin protein levels served as loading control. (B andC) Co-IP experiment in S2 cells indicate that Klhl10 can bind to the BIR domain of dBruce. The immunoprecipitate (IP) is shown at the top, and pre-incubation of whole lysates are shown at the bottom (Input). Cell lysates were incubated with IgG beads which bind to Protein A (PrA). For Western blotting of IPs, (B) anti-dBruce antibody or (C) anti-HA antibody were used. (B) Cells were co-transfected with a dbruce “mini gene” (consisting of the first N-terminal 1,622 amino acids, including the BIR domain, and the last C-terminal 446 amino acids that contain the UBC domain) and (lane 1) PrA-klhl10 or (lane 2) PrA-GFP (see  for details).  (C) Cells were co-transfected with HA-tagged dBruce-BIR peptide containing the first N-terminal 387 amino acids of dBruce that includes the BIR domain region (amino acids 251–321). This motif is sufficient to bind to Klhl10 in S2 cells (see  for details).

A - B Representative Western blot images and the corresponding graphs show the knockdown efficiency of sh ARL13B and sh IFT88 in the ( A ) A549 and ( B ) RPE1 knockdown cells. Knockdown efficiency was quantified by normalizing the signal intensity of the target protein from each knockdown sample to its respective control group. The data represents quantifications from three independent experiments. Statistical analysis is performed using One-way ANOVA followed by Dunnett’s multiple comparisons test. P values: * < 0.05, ** < 0.01, *** < 0.001, **** < 0.0001. ns = not significant. Error bar: SD. C Representative immunofluorescence images show a reduced number of ciliated cells in the ARL13B KD and IFT88 KD groups in A549 (top panel) and RPE1 (bottom panel) cell lines. D - E Graphs depict the percentage of primary cilia-bearing (ciliated) cells in the ARL13B KD and IFT88 KD groups in ( D ) A549 and ( E ) RPE1 respectively. The data represents quantifications from five independent experiments. Statistical analysis is performed using One-way ANOVA followed by Dunnett’s multiple comparisons test. P values: * < 0.05, ** < 0.01, *** < 0.001, **** < 0.0001. ns = not significant. F - G Graphs depict flow cytometry analysis of the relative infection rate of different SARS-CoV-2-GFP pseudovirus variants upon perturbation of primary cilia in the ARL13B - and IFT88- knockdown human lung and retinal cells respectively. The percentage of infected cells was determined by flow cytometry analysis of GFP-positive infected cells. The data represents quantifications from three independent experiments. Each dot represents the mean value of an independent experiment. Statistical analysis is performed using Two-way ANOVA, Tukey's multiple comparisons test. P values: * < 0.05, ** < 0.01, *** < 0.001, **** < 0.0001. ns = not significant. Error bar: S.E.M.
