Why Senescent Cells Are Resistant to Apoptosis: An Insight for Senolytic Development

Frontiers in Cell and Developmental Biology, 2022
Cellular senescence is a process that leads to a state of irreversible cell growth arrest induced by a variety of intrinsic and extrinsic stresses. Senescent cells (SnCs) accumulate with age and have been implicated in various age-related diseases in ...

Bone marrow senescence and the microenvironment of hematological malignancies [PDF]

, 2020
Senescence is the irreversible arrest of cell proliferation that has now been shown to play an important role in both health and disease. With increasing age senescent cells accumulate throughout the body, including the bone marrow and this has been ...

Senolytic compounds control a distinct fate of androgen receptor agonist- and antagonist-induced cellular senescent LNCaP prostate cancer cells

Cell & Bioscience, 2020
Background The benefit of inducing cellular senescence as a tumor suppressive strategy remains questionable due to the senescence-associated secretory phenotype.

Azithromycin and Roxithromycin define a new family of “senolytic” drugs that target senescent human fibroblasts [PDF]

, 2018
Here, we employed a “senolytic” assay system as a screening tool, with the goal of identifying and repurposing FDA-approved antibiotics, for the targeting of the senescent cell population. Briefly, we used two established human fibroblast cell lines (MRC-

Senolytic Treatment With Fisetin Reverses Age‐Related Endothelial Dysfunction Partially Mediated by SASP Factor CXCL12 [PDF]

Aging Cell
Single‐cell transcriptomics identifies that oral, intermittent fisetin supplementation improves endothelial function by targeting senescent endothelial cell‐derived senescence‐associated secretory phenotype (SASP) factors and CXCL12 in old animals. The SASP and specifically CXCL12 were found to drive age‐related endothelial dysfunction by promoting ...

The Evolving Role of CD8+CD28- Immunosenescent T Cells in Cancer Immunology [PDF]

, 2019
Functional, tumor-specific CD8+ cytotoxic T lymphocytes drive the adaptive immune response to cancer. Thus, induction of their activity is the ultimate aim of all immunotherapies.

Impact of sitagliptin on endometrial mesenchymal stem-like progenitor cells : a randomised, double-blind placebo-controlled feasibility trial [PDF]

, 2020
Background: Recurrent pregnancy loss (RPL) is associated with the loss of endometrial mesenchymal stem-like progenitor cells (eMSC). DPP4 inhibitors may increase homing and engraftment of bone marrow-derived cells to sites of tissue injury.

Discovery of senolytics using machine learning

Nature Communications, 2023
AbstractCellular senescence is a stress response involved in ageing and diverse disease processes including cancer, type-2 diabetes, osteoarthritis and viral infection. Despite growing interest in targeted elimination of senescent cells, only few senolytics are known due to the lack of well-characterised molecular targets. Here, we report the discovery

The light and shadow of senescence and inflammation in cardiovascular pathology and regenerative medicine [PDF]

, 2017
Recent epidemiologic studies evidence a dramatic increase of cardiovascular diseases, especially associated with the aging of the world population. During aging, the progressive impairment of the cardiovascular functions results from the compromised ...

Loss of histone macroH2A1 in hepatocellular carcinoma cells promotes paracrine-mediated chemoresistance and CD4+CD25+FoxP3+ regulatory T cells activation [PDF]

, 2020
Rationale: Loss of histone macroH2A1 induces appearance of cancer stem cells (CSCs)-like cells in hepatocellular carcinoma (HCC). How CSCs interact with the tumor microenvironment and the adaptive immune system is unclear. Methods: We screened aggressive
