Conversely, silencing PANO1 leads to a reduction in p14ARF expression, highlighting its pivotal role in apoptotic regulation and tumor suppression, as evidenced by its ability to suppress the tumorigenicity of HeLa cells in animal models."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "3"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Juan Antonio Fafián-Labora, Jose Antonio Rodríguez-Navarro, Ana O'Loghlen "}, {"type": "b", "children": [{"type": "t", "text": "Small Extracellular Vesicles Have GST Activity and Ameliorate Senescence-Related Tissue Damage."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "Cell Metab (2020)"}]}, {"type": "t", "text": " DOI: "}, {"type": "a", "children": [{"type": "t", "text": "10.1016/j.cmet.2020.06.004"}], "href": "https://doi.org/10.1016/j.cmet.2020.06.004"}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "32574561"}], "href": "https://pubmed.ncbi.nlm.nih.gov/32574561"}]}, {"type": "r", "ref": 2, "children": [{"type": "t", "text": "Hua Ni, Xing-Jiang Yu, Hua-Jie Liu, et al.
