Schematic diagram of Golgi microtubules regulating single cell durotaxis For durotactic cells on stiffness gradient gel, the Golgi-nucleus axis determines the distribution of Golgi microtubules, which then regulates FA turnover in response to stiffness gradient.Figure 6For durotactic cells on stiffness gradient gel, the Golgi-nucleus axis determines the distribution of Golgi microtubules, which then regulates FA turnover in response to stiffness gradient. Once the Golgi microtubules were disrupted, cells with unpolarized Golgi and enlarged FAs were unable to migrate upwards the stiffness gradient.

Figure 4(A, B) Sustained local 4-AP administration was associated with increased myelin area and close-to-normal Garea-ratio compared to untreated group, as determined by analysis of 40 randomly chosen myelinated axons from sections of 4 nerves for each group. (**: p<0.0001; ANOVA, with post-hoc comparisons using two-tailed unpaired t-test). 4-AP treated mice had a greater proportion of axons for which the associated myelin area was greater than the mean value for uninjured mice (shown in the green line), with inset figure displaying all axons with values above this mean. (C, D) 4-AP treated nerves also showed increases in the levels of P0 protein as detected by western blot analysis (**:p<0.01; ANOVA, with post-hoc comparisons using two-tailed unpaired t-test). (C, D) 4-AP treated nerves also showed increases in the levels of P0 protein as detected by western blot analysis (**:p<0.01; ANOVA, with post-hoc comparisons using two-tailed unpaired t-test). (E) Increases in P0 protein over time also were observed by immunofluorescence analysis at different time points, with P0 protein expression increasing to a greater extent in nerves of mice treated with 4-AP. Scale bar = 200 m. (F, G) 4-AP treatment increased the number of myelinated axons (**: p=0.002, n=4; ANOVA, with post-hoc comparisons using two-tailed unpaired t-test). Even though the 4-AP treated group also exhibited a greater number of total axons, this difference was not statistically significant. All myelinated and total axons were counted in 5 randomly chosen grids from each of 4 nerves for each group. This experiment represents a single group of mice of one of three replicates on NCV recovery.

Exemplary analysis of cell cycle with Ki67 and nuclear dye. More young HO-1-/- LT-HSCs are in G1 and S/G2/M cell cycle phases. The presented cell cycle analysis is from two independent experiments. Young HO-1-/- MPPs do not differ in cell cycling from young HO-1+/+ MPPs. The presented cell cycle analysis is from two independent experiments. More old HO-1-/- LT-HSCs are in G1 phase in comparison to old HO-1+/+ LT-HSCs, but not in S/G2/M phase. The presented cell cycle analysis is from two independent experiments. Old MPPs do not differ in cell cycling between genotypes. The presented cell cycle analysis is from two independent experiments. Young HO-1-/- LT-HSCs contain more γH2aXhigh cells than young HO-1+/+, 378-991 cells analyzed from 7 mice/group. Young HO-1-/- MPPs contain more γH2aXhigh cells than young HO-1+/+, 1693-2790 cells analyzed from 7 mice/group. Alkaline comet assay revealed that HO-1-/- LT-HSCs possess (L) higher oil tail moment and (M) more DNA in the comet tail. 1068-1189 cells analyzed from 6 mice/group. HSCs from young HO-1-/- mice provide worse hematopoietic reconstitution after transplantation than HO-1+/+ HSCs. Data are shown as mean ± SEM, n = 8-9 mice/group.
Figure 1(A) Cartoon depicting the principle of the endosomal PI4P BRET measurement. The Venus fluorescent protein is targeted to the respective endosomes using Rab proteins, while Renilla luciferase [termed Super luciferase (Sluc)] is fused to the P4M2x PI4P reporter. This reporter binds to PI4P the majority of which is in the PM. The PI4KA inhibitor, GSK-A1 (A1) reduces PI4P in the PM allowing more of the reporter to find the endosomal PI4P that is produced by PI4Ks that are insensitive to GSK-A1. Relocation of the P4M2x reporter tagged with Sluc to the PI4P-rich endosomes will increase the energy transfer between the enzyme and Venus in the presence of the coelenterazine H substrate. (B) Representative confocal images show the distribution of the P4M2x reporter in HEK293-AT1 cells before and after the addition of GSK-A1 (30 nM). Note the signal disappearing from the PM and strongly highlighting the endosomes and Golgi. Scale bars are 20 µ (C) Representative result from a BRET experiment detecting PI4P in various endosomes (Rab7, Rab5 and Rab11) following addition of GSK-A1. The graph shows normalized BRET values where the averages of triplicate measurements of A1-treated cells were divided by the averages of triplicates obtained in DMSO-treated controls. Note that these signals originate from thousands of cells. (D) Similar BRET experiment showing the Rab7-pool of PI4P both in control HEK293-AT1 cells and in two clones of cells with PI4K2A deletion (#20 and #26).

Figure 10PC and PC biosynthesis have become obsolete (blurred). The inhibition of Acc1 (highlighted in red) is essential for shortening average acyl chain length, which in turn is required for maintaining the physical properties of membranes faced with excess PE. The decreased non-bilayer propensity of PE is indicated by its reduced conical shape.
