DNA damage-dependent mechanisms of ionizing radiation-induced cellular senescence [PDF]

PeerJ
Cellular senescence can be broadly categorized into replicative senescence and stress-induced premature senescence. Replicative senescence mainly results from the progressive shortening of telomeres during successive cell divisions, eventually leading to

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Senescence-associated lysosomal dysfunction impairs cystine deprivation-induced lipid peroxidation and ferroptosis

Nature Communications
Senescent cells, characterized by irreversible cell cycle arrest and inflammatory factor secretion, promote various age-related pathologies. Senescent cells exhibit resistance to ferroptosis, a form of iron-dependent cell death; however, the underlying ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Cellular senescence in cancer

BMB Reports, 2019
Cellular senescence, a process of cell proliferation arrest in response to various stressors, has been considered to be important factor in age-related disease. Identification of senescent cells in tissues is limited and the role of senescent cells is poorly understood. Recently however, several studies showed the characterization of senescent cells in

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

Detecting Cellular Senescence in Reprogramming

, 2018
International audienceCellular senescence has been suggested to facilitate tissue regeneration via promoting cellular plasticity. Here, we describe multiple systems, both in vitro and in vivo, to detect senescence in the context of cellular ...

Myc Supports Self-Renewal of Basal Cells in the Esophageal Epithelium

Frontiers in Cell and Developmental Biology, 2022
It is widely believed that cellular senescence plays a critical role in both aging and cancer, and that senescence is a fundamental, permanent growth arrest that somatic cells cannot avoid. Here we show that Myc plays an important role in self-renewal of

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.

Control of mesenchymal stromal cell senescence by tryptophan metabolites

, 2021
[[abstract]]Cellular senescence contributes to aging and age-related disorders. High glucose (HG) induces mesenchymal stromal/stem cell (MSC) senescence, which hampers cell expansion and impairs MSC function.
