(A) Kasumi-3 and CD34 + HPCs were efficiently infected with the NR-1 strain of <t>HCMV.</t> Kasumi-3 and HPCs were either mock-infected or infected with a GFP-expressing NR-1 strain at the indicated multiplicities of infection (MOIs). Two days later, the cells were analyzed for GFP expression by flow cytometry. An MOI of 5 was used for the following experiment. (B) The maintenance of the NR-1 genome, the suppression of viral IE1 and the presence of latency-associated UL138 over a 10-day time course. DNA and total RNA were isolated from Kasumi-3 cells and HPCs at various time points after infection. Viral genomic DNA was assayed by PCR, and RNA molecules encoding IE1 and UL138 were assayed by RT-PCR. In both cases, gel electrophoresis was used to detect the products of the reactions. (C) Reactivation of NR-1 virus in infected Kasumi-3 cells and HPCs. Kasumi-3 cells and HPCs were latently infected along a 10-day time course. Then, a subset of each cell population was cultured for an additional 2 days under conditions favoring lytic reactivation: Kasumi-3 cells were exposed to TPA, while HPCs were grown in reactivation medium. Following this, total RNA was extracted from the cells, and the ratio of IE1 to UL138 cDNA expression was assessed by qRT-PCR in triplicate. (D) Release of infectious progeny virions in latently infected Kasumi-3 cells and HPCs following reactivation treatment. Latently infected or mock-infected Kasumi-3 cells and HPCs were cultured under conditions favoring lytic reactivation (described above) or control conditions for 6 days, after which the cells were washed with PBS and co-cultured with HFFs for 2 days. Then, the Kasumi-3 cells were removed from the co-cultures, and the HFFs were washed with PBS and cultured for an additional 5 days for fluorescence microscopy analysis of GFP-positive plaques. (E) miR-UL148D showed robust accumulation during the establishment of experimental HCMV latency in Kasumi-3 cells. In total, 20,000 infected cells were harvested for the isolation of total RNA and DNA at each indicted time point along the 10-day time course. Viral DNA was first quantified by qPCR, and then absolute viral genomes copies were calculated by generating a standard curve. HCMV miRNAs were then assayed with a HCMV miRNA probe kit, and their levels were calculated using a standard curve. The HCMV miRNA level per virus was calculated by dividing the amount of each HCMV miRNA by the virus copy number. (F) miR-UL148D accumulated in HPCs latently infected with NR-1. HCMV miRNA levels in NR-1-infected HPCs were determined as described above. Values are shown as the mean ± SEM (n = 3). **, P<0.01.

IE1 (immediately early), UL54 (early lytic transcript), and UL99 (late lytic transcript). Total RNA was isolated from infected cells and assayed by RT-qPCR. Samples were assayed in triplicate, and GAPDH level was used for normalization.

Model of Cav1α function in the regulation of primary cilia length. In control cells (left), Cav1α localizes in non-caveolar domains at the apical membrane of MDCK cells, where it positively regulates RhoA activity. Active RhoA subsequently promotes apical actin polymerization through its effectors ROCK1 and DIA1. Actin meshwork rearrangement regulates ciliary lengthening by controlling the access of transport vesicles to the centrosomal zone. In the absence of Cav1α (right), RhoA activation is impaired and less apical actin polymerizes, allowing the arrival of more material at the centrosome that is used to assemble longer cilia.

Figure 2. Decreased trafficking to primary cilia upon depletion of DIAPH2 and DIAPH3. A–D, depletion of DIAPH2 or DIAPH3 decreased trafficking to cilia. A and B, hTERT-RPE1 cells were transfected with siCtr, siDIAPH3, or siDIAPH3 plus the rescue construct myc-DIAPH3 for 48 h. Later cells were fixed and stained for (A) Arl13B and PC1 or (B) acetylated tubulin, Eb3 (as basal body marker) and IFT88. Scale bars are 5.00 μm for the represented images. C, depletion of DIAPH2 reduced in the level of IFT88, PC1, and tubulin acetylation with no change in Arl13B in primary cilia. Box-and-whisker plots (as defined for Fig. 1C) are used to display average fluorescence intensity of Arl13B, PC1, acetylated tubulin, and IFT88 upon DIAPH2 depletion and rescue. Fluorescence intensity was measured as the average intensity over the entire cilium (see Fig. S3E) and therefore normalized for length. The rescue for Arl13B was not done (nd). D, reduction of IFT88 and tubulin acetylation levels was detected upon depletion of DIAPH3. Average fluorescence intensity was measured to determine protein levels of Arl13B, PC1, acetylated tubulin, and IFT88 upon DIAPH3 depletion and rescue. The rescue for Arl13B and PC1 was not done (nd). Box-and-whisker plots are used to display average fluorescence intensity. Three independent experiments; n = 50 cells each.

Cells were transfected with GFP-CNTN1 (control) or GFP-CNTN1-DIAPH3, and samples were western blotted for GFP, GAPDH, Arf4, and IF20. Three independent experiments were conducted with n = 50 cells each, *p < 0.05, **p < 0.01, ***p < 0.005, ****p < 0.001. Two-tailed t-test analysis was done to compare GFP-CNTN1 control with GFP-CNTN1-DIAPH3.

Figure Lengend Snippet: Figure 4. Trafficking of post-Golgi and endosomal vesicles is increased upon targeting DIAPH3 to the base of cilia. A–G, targeting DIAPH3 to the base of cilia increased cargo trafficking. hTERT-RPE1 cells were transfected with GFP-CNTN1 or GFP-CNTN1-DIAPH3, and after 24 h of serum starvation, cells were fixed and stained for acetylated tubulin, GFP and (A) Arf4, (B) IFT20, (C) Rab11, (D) BBS1, or (E) GFP. Scale bars are 3 μm for each image. F, quantifications of the total protein fluorescence intensity scan at the base of cilia was conducted for Arf4, IFT20, Rab11, BBS1, or GFP. G, DIAPH3 targeted to the ciliary base via PACT increases the recycling endosome (Rab11) protein level at the base of the cilia. Cells were transfected with GFP-PACT or GFP-PACT-DIAPH3 and after 24-h serum starvation, were fixed and stained for acetylated tubulin, GFP, and Rab11. Quantification of the Rab11 fluorescence protein intensity scan was conducted. For panels F and G, box and whisker plots (as defined in Fig. 1C) are shown. H, targeting DIAPH3 to the base of cilia has no effect on protein levels of Arf4 or IFT20. Cells were transfected with GFP-CNTN1 (control) or GFP-CNTN1-DIAPH3, and samples were western blotted for GFP, GAPDH, Arf4, and IF20. Three independent experiments were conducted with n = 50 cells each, *p < 0.05, **p < 0.01, ***p < 0.005, ****p < 0.001. Two-tailed t-test analysis was done to compare GFP-CNTN1 control with GFP-CNTN1-DIAPH3.

Article Snippet: BBS1 (21118-1-AP), Arl13B (1711-1-AP), DIAPH3 (14342-1-AP), IFT20 (13615-1- AP), Rab11 (20220-1-AP), and IFT88 (139671-1-AP) were obtained from Proteintech (Rosemont, Illinois, United States).

Figure 5. Microtubule function of DIAPH3 regulates ciliogenesis and cilia length. A–C, disruption of microtubule but not actin functions of DIAPH3 negatively impacts ciliogenesis and cilia length. hTERT-RPE1 cells were transfected with siCtr or siDIAPH3, and cells were rescued using wild-type constructs of GFP-DIAPH3WT (wildtype), GFP-DIAPH3ACT (mutation preventing actin polymerization), GFP-DIAPH3MT (mutation preventing microtubule stabilization), GFP-CETN1-DIAPH3, or GFP-CETN1. A, western blots of samples were blotted for human-specific anti-DIAPH3, GFP, and GAPDH. Quantifications for (B) ciliation and (C) cilia length were conducted. D, reduction of IFT20, Rab11, and IFT88 levels at the cilia following DIAPH3 depletion cannot be rescued by DIAPH3MT. Cells were starved for 24 h, fixed, and stained for acetylated tubulin, GFP, and IFT20 or Rab11 or IFT88. For panels C and D, box and whisker plots (as defined in Fig. 1C) are shown. Error bars represent ± SD of three independent experiments; n = 50 each, *p < 0.05, **p < 0.01, ***p < 0.005, ****p < 0.001. Two-tailed t-test analysis was done to compare siCtr control with all samples or to compare siDIAPH3 with all samples. For panel C, one-way ANOVA statistical testing was also conducted on the all samples excluding the siCtr (p = 0.0001) or including siCtr (p = 0.000004) indicating that a significant difference was detected among populations.
