    A Non-stop identity complex (NIC) supervises enterocyte identity and protects from premature aging

    Neta Erez et al.
    A nuclear Non-stop identity complex (NIC) supervises enterocyte (EC) identity, preserves tissue homeostasis, and prevents premature aging by maintaining EC-specific gene expression, silencing non-relevant programs, and safeguarding large-scale nuclear organization.

    PUMILIO hyperactivity drives premature aging of Norad-deficient mice

    Florian Kopp et al.
    Long noncoding RNA Norad performs an essential function in mammalian physiology by inhibiting the activity of PUMILIO RNA binding proteins, thereby suppressing a multi-system degenerative phenotype resembling premature aging.

    Haploinsufficiency of Trp53 dramatically extends the lifespan of Sirt6-deficient mice

    Shrestha Ghosh et al.
    The dramatic extension of lifespan in Sirt6-deficient mice by Trp53 haploinsufficiency suggests that SIRT6 has distinct biological function from SIRT1 in regulating p53 activity and preventing cells from senescence/apoptosis.

    Progerin reduces LAP2α-telomere association in Hutchinson-Gilford progeria

    Alexandre Chojnowski et al.
    Expression of the lamina-associated polypeptide α (LAP2α) prevents premature cellular ageing caused by expression of progerin in Hutchinson-Gilford progeria syndrome.

    celsr1a is essential for tissue homeostasis and onset of aging phenotypes in the zebrafish

    Chunmei Li et al.
    The use of forward genetic screens in zebrafish identifies a new model of vertebrate aging, defining the regulating of the onset of aging phenotypes through maintenance of progenitor cell populations.

    Casein kinase 1G2 suppresses necroptosis-promoted testis aging by inhibiting receptor-interacting kinase 3

    Dianrong Li et al.
    Casein kinase 1G2 interacts with and inhibits the activation of receptor-interacting kinase 3, RIP3, in response to TNF and toll-like receptor family members and attenuates its necroptosis signaling activity.

    Deficit of mitogen-activated protein kinase phosphatase 1 (DUSP1) accelerates progressive hearing loss

    Adelaida M Celaya et al.
    Mitogen-activated protein kinase phosphatase 1 (DUSP1) deficiency causes early redox imbalance and increased inflammatory response in the cochlea, leading to cell loss and progressive neurosensory hearing loss.

    Coordinated control of senescence by lncRNA and a novel T-box3 co-repressor complex

    Pavan Kumar P et al.
    A novel master regulatory mechanism of cell proliferation and senscence employs the lncRNA UCA1 and a CAPERα/TBX3 corepressor.

    Direct reprogramming of human smooth muscle and vascular endothelial cells reveals defects associated with aging and Hutchinson-Gilford progeria syndrome

    Simone Bersini et al.
    Direct reprogramming of smooth muscle cells from HGPS patients revealed that BMP4 is a key contributor of vascular degeneration and might represent a new therapeutic target.
