  • Turning gene expression up and down

    CRISPR-based technologies facilitate genome manipulation to understand the function of specific elements and have even entered the clinic to treat disease via modulation of gene expression. Existing approaches to screen regulatory effects in the…

  • Deep-sea-floor diversity in Asteroidea is shaped by competing processes across different latitudes and oceans

    Deep-sea-floor diversity in Asteroidea is shaped by competing processes across different latitudes and oceans

    Global patterns of species richness

    At a global scale, species richness peaks ~10° N of the Equator in shallow tropical waters (Fig. 2a,c) with a strong decline in species number throughout temperate waters on both sides of the Equator,…

  • Time-varying stimuli that prolong IKK activation promote nuclear remodeling and mechanistic switching of NF-κB dynamics

    Time-varying stimuli that prolong IKK activation promote nuclear remodeling and mechanistic switching of NF-κB dynamics

    IL-1 pulse duration produces a monotonic correlation between same-cell IKK and NF-κB responses

    We previously developed a CRISPR-modified U2OS cell line that co-express FP fusions of NEMO (EGFP-NEMO) and RelA (mCh-RelA) from their endogenous loci….

    Suicide gene therapy targeting ewing sarcoma via an ewing-specific GGAA promoter

    Cell lines

    The Ewing sarcoma cell line A673 (CRL-1598), the fibrosarcoma cell line HT1080 (CCL-121) and the osteosarcoma cell lines U2-OS (HTB-96) and Saos-2 (HTB-85) were purchased from the American Type Culture Collection (Manassas, VA, USA)….

  • A call for funds and training for kidney genomics programmes

    A call for funds and training for kidney genomics programmes

    In countries with resource constraints, lack of access to genetic testing leads to under-diagnosis of genetic kidney diseases, resulting in a missed opportunity to initiate treatment to prevent kidney failure. Funding, education and engagement…

  • Accelerated wound healing through tannin-rich Jaft extract, concentration-dependent efficacy and mechanistic insights from Quercus brantii ointment formulations

    Accelerated wound healing through tannin-rich Jaft extract, concentration-dependent efficacy and mechanistic insights from Quercus brantii ointment formulations

    Reactive oxygen species (ROS) play a dual role in wound healing, where both excessive production and inadequate detoxification can lead to oxidative stress, exacerbating inflammation and delaying tissue repair12. This underscores the importance…

  • Structure and function of the human apoptotic scramblase Xkr4

    Structure and function of the human apoptotic scramblase Xkr4

    Full length hXkr4 scrambles lipids

    To test whether Xkr proteins are scramblases we sought to purify and functionally reconstitute them in proteoliposomes. A screen of GFP-tagged family members using fluorescence size exclusion chromatography…

  • The therapeutic potential of pegylated arginase I treatment in glioblastoma

    The therapeutic potential of pegylated arginase I treatment in glioblastoma

    Cell cultures

    GBM cell lines U87 (HTB-14), U373 (HTB-19), and U138 (HTB-16) were purchased from American Type Culture Collection (Virginia, USA). D54 was a gift from Duke University Medical Center, Durham, NC, USA23. The mouse microglia cell line…
