Characteristics of senescence in primary human mesenchymal stem cells (hMSCs) cultured to late passage (LP) were increased relative to those in donor-matched cells at early passage (EP). LP cells were examined at the passage number where onset of senescence occurred i.e. further cell proliferation was halted. This point was found to vary between donors (see Table 1 in the Materials and Methods section). Comparisons were made between donor-matched samples of senescent LP and EP cells at passage 3: (A) LP hMSCs showed positive staining for β-galactosidase. (B) Quantitative mass spectrometry proteomics (Fig. 1A) showed a corresponding significant increase in β-galactosidase protein (GLB1, p < 0.0001) in LP vs. EP cells, and significant loss of the senescence marker lamin-B1 (LMNB1, p < 0.0001) (Shimi et al, 2011). Log2 fold-changes and significance values corrected for Benjamini-Hochberg false discovery rate (BH-FDR) were calculated as described previously (Mallikarjun et al, 2020); n = 4 primary donors. (C) RT-qPCR also showed a corresponding significant decrease of LMNB1 transcript in LP vs. EP hMSCs (p < 0.0001 established by t- test; normalisation to housekeeping gene PPIA; n = 4 primary donors). (D) An analysis of cell morphology showed that LP hMSCs had significantly larger spread areas than EP cells (p < 0.0001 established by ANOVA testing, with ≥ 39 cells imaged per condition), consistent with established senescence phenotype (Hernandez-Segura et al, 2018).

E. Carey at the University of Michigan, Ann Arbor, MI. The UM-SCC cell lines were derived from eight patients with SCC of the upper aerodigestive tract (supplemental Table 1). Patient age at tumor diagnosis ranged from 37 to 72 years. The cell lines selected were obtained from patients with stage I-IV tumors, distributed among oral, pharyngeal and laryngeal sites. All the patients had aggressive disease, with early recurrence and death within two years of therapy. Cell lines established from single isolates of a patient specimen are designated by a numeric designation, and where isolates from two time points or anatomical sites were obtained, the designation includes an alphabetical suffix (i.e., "A" or "B"). The cell lines were maintained in Eagle's minimal essential media supplemented with 10% fetal bovine serum and penicillin/streptomycin.

  • Defining Functional Interactions During Biogenesis of Epithelial Junctions
    ARTICLE Received 11 Dec 2015 | Accepted 13 Oct 2016 | Published 6 Dec 2016 | Updated 5 Jan 2017 DOI: 10.1038/ncomms13542 OPEN Defining functional interactions during biogenesis of epithelial junctions J.C. Erasmus1,*, S. Bruche1,*,w, L. Pizarro1,2,*, N. Maimari1,3,*, T. Poggioli1,w, C. Tomlinson4,J.Lees5, I. Zalivina1,w, A. Wheeler1,w, A. Alberts6, A. Russo2 & V.M.M. Braga1 In spite of extensive recent progress, a comprehensive understanding of how actin cytoskeleton remodelling supports stable junctions remains to be established. Here we design a platform that integrates actin functions with optimized phenotypic clustering and identify new cytoskeletal proteins, their functional hierarchy and pathways that modulate E-cadherin adhesion. Depletion of EEF1A, an actin bundling protein, increases E-cadherin levels at junctions without a corresponding reinforcement of cell–cell contacts. This unexpected result reflects a more dynamic and mobile junctional actin in EEF1A-depleted cells. A partner for EEF1A in cadherin contact maintenance is the formin DIAPH2, which interacts with EEF1A. In contrast, depletion of either the endocytic regulator TRIP10 or the Rho GTPase activator VAV2 reduces E-cadherin levels at junctions. TRIP10 binds to and requires VAV2 function for its junctional localization. Overall, we present new conceptual insights on junction stabilization, which integrate known and novel pathways with impact for epithelial morphogenesis, homeostasis and diseases. 1 National Heart and Lung Institute, Faculty of Medicine, Imperial College London, London SW7 2AZ, UK. 2 Computing Department, Imperial College London, London SW7 2AZ, UK. 3 Bioengineering Department, Faculty of Engineering, Imperial College London, London SW7 2AZ, UK. 4 Department of Surgery & Cancer, Faculty of Medicine, Imperial College London, London SW7 2AZ, UK.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

C.E.Hubb. during dehydration and rehydration i Abstract Plants, as sessile organisms must continually adapt to environmental changes. Water deficit is one of the major environmental stresses that affects plants. While most plants can tolerate moderate dehydration
