Figure Lengend Snippet: ORP6 RNAi decreases cell motility of primary cultured cerebellar granule cells (CGCs). Cell-tracking images of primary cultured CGCs transfected with control RNA (A) or ORP6 RNAi (B), stained with Hoechst. (C) The accumulated distance of primary cultured CGCs transfected with control or ORP6 RNAi is automatically analyzed by PerkinElmer Harmony 4.9 Image Analysis Software. All colored arrows indicate the distance and direction of cell movement. Data are collected from five independent cell culture preparations, and the accumulated distance of each two groups is shown as the mean ± SE. Statistical analysis is performed using Welch's t -test. A P value less than 0.05 is considered statistically significant. Bars, 50 μm.

Figure Lengend Snippet: ORP6 int impaired the migration of cerebellar granule cells (CGCs) in the developing cerebellum. (A) Experimental design of gene transfection into P7 mice cerebellum by in vivo electroporation and tissue collection. Sagittal section of P9 cerebellum transfected with pCAGGS-AcGFP-C (B–D) or pCAGGS-AcGFP-C-ORP6 int (E–G), and immunostained with anti-calbindin antibody (C and F). The cerebellar laminar structure is identified as follows: the calbindin-positive Purkinje cell layer (PCL) and molecular layer (ML), which lies superficial to the PCL and contains sparsely Hoechst-stained nuclei. The external granular layer is the outermost layer of the ML, a region with dense Hoechst-stained nuclei, and the internal granular layer located beneath the calbindin-positive PCL. Arrows indicate distribution of CGCs expressing pCAGGS-AcGFP-C or pCAGGS-AcGFP-C-ORP6 int. Ratio of cells transfected with pCAGGS-AcGFP-C (H) or pCAGGS-AcGFP-C-ORP6 int (I) in each layer to total cells. Data are collected from four animals, and the cell number of each two groups is shown as the mean ± SE. Statistical analysis is performed using Welch's t -test. A P value less than 0.05 is considered statistically significant. Bars, 50 μm.

Article Snippet: After LPS stimulation (10 μg mL −1 , 12 h, ServiceBio, GC205009 ) to induce an inflammatory phenotype, cells were treated with hydrogel extracts (Hy, AdHy, AdHy@Pae) for 24 h. Cells were then washed twice with PBS, harvested, and fixed overnight at 4 °C in 70% cold ethanol; after washing, they were stained with 500 μL cell-cycle staining solution (MULTI SCIENCES, CCS012) for 30 min in the dark.

Figure Lengend Snippet: S6K1 inhibition alleviates neuronal necroptosis through SGK1 following TBI in mice. (A, K) Western blotting showed increased expression of p-S6/S6, SGK1, p-MLKL/MLKL, and p-RIP3/RIP3 in the cortex following TBI. These changes were attenuated by S6K1 inhibitor treatment and S6K1 knockdown, as shown by decreased p-MLKL/MLKL and p-RIP3/RIP3 levels compared with the TBI group.
