Polyamine depletion limits progression of acute leukaemia

Cancer cells are addicted to polyamines, polycations essential for cellular function. While dual targeting of cellular polyamine biosynthesis and polyamine uptake is under clinical investigation in solid cancers, preclinical and clinical studies into its potential in haematological malignancies are lacking. Here we investigated the preclinical efficacy of polyamine depletion in acute leukaemia.

Imaging Flow Cytometric Identification of Chromosomal Defects in Paediatric Acute Lymphoblastic Leukaemia

Acute lymphoblastic leukaemia is the most common childhood malignancy that remains a leading cause of death in childhood. It may be characterised by multiple known recurrent genetic aberrations that inform prognosis, the most common being hyperdiploidy.

Imaging of Abdominal Complications in Children With Acute Lymphoblastic Leukaemia

Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy and remains one of the most common causes of cancer-related death in children and adolescents. Five-year overall survival rates now exceed 90% with current multidrug chemotherapeutic regimens.

The Cold Atmospheric Plasma Inhibits Cancer Proliferation Through Reducing Glutathione Synthesis

Cold atmospheric plasma (CAP) is a safe and effective alternative to radiotherapy for cancer treatment. Its anticancer effects are attributed to increased intracellular reactive oxygen species (ROS). Glutathione, a key antioxidant derived from glutamine, is critical for cell proliferation. This study investigated whether CAP-induced ROS elevation results from reduced glutamine-glutathione conversion and elucidates the underlying mechanisms.

Constitutive Activation of RAS/MAPK Pathway Cooperates with Trisomy 21 and Is Therapeutically Exploitable in Down Syndrome B-cell Leukemia

Children with Down syndrome (constitutive trisomy 21) that develop acute lymphoblastic leukemia (DS-ALL) have a 3-fold increased likelihood of treatment-related mortality coupled with a higher cumulative incidence of relapse, compared with other children with B-cell acute lymphoblastic leukemia (B-ALL).

Targeting cytokine- and therapy-induced PIM1 activation in preclinical models of T-cell acute lymphoblastic leukemia and lymphoma

IL7 and glucocorticoids coordinately drive aberrant activation of PIM1 and suggests that T-ALL and T-LBL patients could benefit from PIM inhibition

Challenges posed by COVID-19 to children with cancer

Development of standardised guidance by national and regional authorities for reducing the risk of SARS-CoV-2 transmission to children with cancer

Germline Elongator mutations in Sonic Hedgehog medulloblastoma

Genetic predisposition to proteome instability may be a determinant in the pathogenesis of paediatric brain cancers

PTPN2 phosphatase deletion in T cells promotes anti-tumour immunity and CAR T-cell efficacy in solid tumours

Our findings define PTPN2 as a target for bolstering T-cell-mediated anti-tumour immunity and CAR T-cell therapy against solid tumours.
