Abstract
The risk of aberrant growth of induced pluripotent stem cell (iPSC)-derived cells in response to DNA damage is a potential concern as the tumor suppressor genes TP53 and CDKN2A are transiently inactivated during reprogramming. Herein, we evaluate the integrity of cellular senescence pathways and DNA double-strand break (DSB) repair in Sendai virus reprogrammed iPSC-derived human fibroblasts (i-HF) compared to their parental skin fibroblasts (HF). Using transcriptomics analysis and a variety of functional assays, we show that the capacity of i-HF to enter senescence and repair DSB is not compromised after damage induced by ionizing radiation (IR) or the overexpression of H-RASV12. Still, i-HF lines are transcriptionally different from their parental lines, showing enhanced metabolic activity and higher expression of p53-related effector genes. As a result, i-HF lines generally exhibit increased sensitivity to various stresses, have an elevated senescence-associated secretory phenotype (SASP), and cannot be immortalized unless p53 expression is knocked down. In conclusion, while our results suggest that i-HF are not at a greater risk of transformation, their overall hyperactivation of senescence pathways may impede their function as a cell therapy product.

Short senolytic or senostatic interventions rescue progression of radiation-induced frailty and premature ageing in mice. eLife 2022; 11:75492. [PMID: 35507395 PMCID: PMC9154747 DOI: 10.7554/elife.75492] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 05/03/2022] [Indexed: 12/24/2022] Open
Abstract
Cancer survivors suffer from progressive frailty, multimorbidity, and premature morbidity. We hypothesise that therapy-induced senescence and senescence progression via bystander effects are significant causes of this premature ageing phenotype. Accordingly, the study addresses the question whether a short anti-senescence intervention is able to block progression of radiation-induced frailty and disability in a pre-clinical setting. Male mice were sublethally irradiated at 5 months of age and treated (or not) with either a senolytic drug (Navitoclax or dasatinib + quercetin) for 10 days or with the senostatic metformin for 10 weeks. Follow-up was for 1 year. Treatments commencing within a month after irradiation effectively reduced frailty progression (p<0.05) and improved muscle (p<0.01) and liver (p<0.05) function as well as short-term memory (p<0.05) until advanced age with no need for repeated interventions. Senolytic interventions that started late, after radiation-induced premature frailty was manifest, still had beneficial effects on frailty (p<0.05) and short-term memory (p<0.05). Metformin was similarly effective as senolytics. At therapeutically achievable concentrations, metformin acted as a senostatic neither via inhibition of mitochondrial complex I, nor via improvement of mitophagy or mitochondrial function, but by reducing non-mitochondrial reactive oxygen species production via NADPH oxidase 4 inhibition in senescent cells. Our study suggests that the progression of adverse long-term health and quality-of-life effects of radiation exposure, as experienced by cancer survivors, might be rescued by short-term adjuvant anti-senescence interventions.

Ripk3 signaling regulates HSCs during stress and represses radiation-induced leukemia in mice. Stem Cell Reports 2022; 17:1428-1441.

Abstract
Receptor-interacting protein kinase 3 (Ripk3) is one of the critical mediators of inflammatory cytokine-stimulated signaling. Here we show that Ripk3 signaling selectively regulates both the number and the function of hematopoietic stem cells (HSCs) during stress conditions. Ripk3 signaling is not required for normal homeostatic hematopoiesis. However, in response to serial transplantation, inactivation of Ripk3 signaling prevents stress-induced HSC exhaustion and functional HSC attenuation, while in response to fractionated low doses of ionizing radiation (IR), inactivation of Ripk3 signaling accelerates leukemia/lymphoma development. In both situations, Ripk3 signaling is primarily stimulated by tumor necrosis factor-α. Activated Ripk3 signaling promotes the elimination of HSCs during serial transplantation and pre-leukemia stem cells (pre-LSCs) during fractionated IR by inducing Mlkl-dependent necroptosis. Activated Ripk3 signaling also attenuates HSC functioning and represses a pre-LSC-to-LSC transformation by promoting Mlkl-independent senescence. Furthermore, we demonstrate that Ripk3 signaling induces senescence in HSCs and pre-LSCs by attenuating ISR-mediated mitochondrial quality control. Ripk3-Mlkl signaling is not required for normal homeostatic hematopoiesis Ripk3-Mlkl signaling promotes HSC loss during serial transplantation or low-dose IR Tnf-α-Ripk3 signaling prevents leukemia development after exposure to low-dose IR Ripk3 represses pre-LSCs by inducing Mlkl necroptosis and PDC-OXPHOS-ROS senescence

The Intracerebroventricular Injection of Murine Mesenchymal Stromal Cells Engineered to Secrete Epidermal Growth Factor Does Not Prevent Loss of Neurogenesis in Irradiated Mice.

Abstract
Decreased neurogenesis after brain exposure to ionizing radiation is linked to neurocognitive impairments. Using transgenic mouse models, we previously showed that abrogation of radiation-induced senescence, or apoptosis, can partially rescue neurogenesis in the subventricular and hippocampus regions. Here, we evaluate whether the injection of recombinant epidermal growth factor (rEGF) or mesenchymal stromal cells (MSC) engineered to secrete EGF (MSC-EGF) can preserve neurogenesis. Using doublecortin (Dcx) expression and BrdU incorporation assays, we found that the injection of rEGF into the subventricular zone (SVZ) promotes neurogenesis, despite increasing apoptosis, in the brain of irradiated mice. The effect of rEGF was mostly localized, as Dcx expression was not induced in the hippocampus region and limited in the contralateral SVZ. Surprisingly, the injection of bone marrow-derived MSC alone, or secreting EGF, did not result in increased neurogenesis despite the fact that part of the MSC survived a few weeks after injection. Our results suggest that only a supraphysiological concentration of rEGF can promote neurogenesis, likely through a direct mitogenic effect.

Abstract
Radiation-induced bystander effect is a biological response in nonirradiated cells receiving signals from cells exposed to ionising radiation. The aim of this in vivo study was to analyse whether extracellular vesicles (EVs) originating from irradiated mice could induce modifications in the redox status and expression of radiation-response genes in bystander mice. C57BL/6 mice were whole-body irradiated with 0.1-Gy and 2-Gy X-rays, and EVs originating from mice irradiated with the same doses were injected into naïve, bystander mice. Lipid peroxidation in the spleen and plasma reactive oxygen metabolite (ROM) levels increased 24 h after irradiation with 2 Gy. The expression of antioxidant enzyme genes and inducible nitric oxide synthase 2 (iNOS2) decreased, while cell cycle arrest-, senescence- and apoptosis-related genes were upregulated after irradiation with 2 Gy. In bystander mice, no significant alterations were observed in lipid peroxidation or in the expression of genes connected to cell cycle arrest, senescence and apoptosis. However, there was a systemic increase in the circulating ROM level after an intravenous EV injection, and EVs originating from 2-Gy-irradiated mice caused a reduced expression of antioxidant enzyme genes and iNOS2 in bystander mice. In conclusion, we showed that ionising radiation-induced alterations in the cellular antioxidant system can be transmitted in vivo in a bystander manner through EVs originating from directly irradiated animals.

Abstract
Some studies show eliminating senescent cells rejuvenate aged mice and attenuate deleterious effects of chemotherapy. Nevertheless, it remains unclear whether senescence affects immune cell function. We provide evidence that exposure of mice to ionizing radiation (IR) promotes the senescent‐associated secretory phenotype (SASP) and expression of p16INK4a in splenic cell populations. We observe splenic T cells exhibit a reduced proliferative response when cultured with allogenic cells in vitro and following viral infection in vivo. Using p16‐3MR mice that allow elimination of p16INK4a‐positive cells with exposure to ganciclovir, we show that impaired T‐cell proliferation is partially reversed, mechanistically dependent on p16INK4a expression and the SASP. Moreover, we found macrophages isolated from irradiated spleens to have a reduced phagocytosis activity in vitro, a defect also restored by the elimination of p16INK4a expression. Our results provide molecular insight on how senescence‐inducing IR promotes loss of immune cell fitness, which suggest senolytic drugs may improve immune cell function in aged and patients undergoing cancer treatment.

Abstract
BACKGROUND p16 protein is significantly down-regulated in several cancers, which reveals that it may be a potential biomarker for cancers. However, the clinicopathological and prognostic value of p16 protein in nasopharynx cancer patients remains unclear. Therefore, we performed a meta-analysis to assess the relationships of p16 protein expression with the clinicopathological features and prognosis of nasopharynx cancer. METHODS PubMed, Web of Science, Embase, and Chinese CNKI were searched to obtain eligible data. The relationships of p16 protein expression with risk, clinicopathological features, and prognosis of nasopharynx cancer were analyzed with stata 14.0 software. The pooled odds ratio (OR) with 95% CI (confidence interval) and hazards ratio (HR) with 95% CI were calculated to evaluate the association between p16 protein expression and nasopharynx cancer. RESULTS A total of 28 studies with 2612 nasopharynx cancer patients were included in the meta-analysis. p16 protein expression was significantly associated with the risk, lymph node metastasis, TNM-stage (tumor-node-metastasis), distant metastasis, and T stage of nasopharynx cancer (Risk, OR = 17.82, 95% CI = 11.20-28.35; Lymph node metastasis, OR = 2.11, 95% CI = 1.42-3.14; TNM-stage, OR = 2.25, 95% CI = 1.54-3.28; Distant metastasis, OR = 3.43, 95% CI = 1.55-7.58; T-stage, OR = 1.72, 95% CI = 1.27-2.33). The negative rate of p16 protein expression in control group was 8.77%, while the negative rate of p16 protein expression in the nasopharynx cancer tissue was 63.78%. However, no significant associations of p16 expression with the overall survival and progression-free survival of nasopharynx cancer were found. CONCLUSION The meta-analysis revealed that downregulated p16 expression was significantly associated with the risk, lymph node metastasis, TNM-stage, distant metastasis, and T stage of nasopharynx cancer. No significant association between p16 protein expression and prognosis of nasopharynx cancer was found. However, additional high-quality and multicenter studies should be conducted to validate these findings in the future.
