    Article Title: Cytotoxicity of curcumin derivatives in ALK positive non-small cell lung cancer.
    Article Snippet: Non-small cell lung cancer with ALK rearrangements can be targeted effectively with ALK inhibitors such as crizotinib.. However, cancer progression typically occurs within a year as drug resistance develops.. One strategy to overcome this drug resistance is to determine if novel cytotoxic agents retain the ability to kill lung cancer cells that have developed ALK inhibitor resistance.

    hfNCSC-sEVs enhance tube formation and barrier function in PCs and promote tight junction protein expression. (A) Optical micrographs of the tube formation assay and (B) statistical analyses demonstrated the number of junctions and total length of tubes in PCs in both the phosphate-buffered saline (PBS) and hfNCSC-sEVs groups ( n = 5 per group). (C) Measurements of transmembrane resistance ( n = 3 per group) and (D) cell monolayer permeability assays ( n = 9 per group) indicated the barrier formation ability of PCs in both the PBS and hfNCSC-sEVs groups. (E) Western blot and (F) statistical analyses revealed the relative protein expression levels of the tight junction proteins zonula occludens 1 (ZO1) and claudin-1 in PCs from the PBS and hfNCSC-sEVs groups on day 7 of in vitro culture (normalized to β-actin, n = 3 per group). (G, H) Immunofluorescence staining (G) and statistical analyses (H) showed the integrated optical density (IOD) of ZO1 (green) and the expression <t>of</t> <t>β-tubulin</t> (red) in PCs from the PBS and hfNCSC-sEVs groups on day 7 of in vitro culture ( n = 3 per group). (I) Schematic illustration of the rat sciatic nerve defect model: a 5-mm defect was surgically created in the rat sciatic nerve, which was then bridged using a silicon tube, followed by an orthotopic injection procedure. (J) Immunofluorescence staining revealed the expression of claudin-1 (red) in the proximal end of regenerated tissue in both the PBS and hfNCSC-sEVs groups on day 7 post-operation, with 4′,6-diamidino-2-phenylindole (DAPI) staining indicating the nuclei. Data are expressed as the mean ± SEM. * P < 0.05, *** P < 0.001 (Student’s t -test for B, C, D, F, and H). The data were from at least three separate and independent studies. hfNCSCs: Hair follicle neural crest stem cells; IOD: integrated optical density; PCs: perineurial cells; sEVs: small extracellular vesicles; ZO1: zonula occludens 1.

    miR-21-5p in hfNCSC-sEVs augments cell proliferation and migration by enhancing HAS2 expression in PCs. (A, B) Western blot (A) and statistical analyses (B) revealed the relative protein expression levels of HAS2, proliferating cell nuclear antigen (PCNA), and vimentin in PCs across the –/–, –/si- Has2 , hfNCSC-sEVs/–, and hfNCSC-sEVs/si- Has2 groups on day 5 of in vitro culture (normalized to β-actin, n = 3 per group).
