Abstract
Medulloblastoma (MB) is the most common and aggressive paediatric brain tumour. Although the cure rate can be as high as 70%, current treatments (surgery, radio- and chemotherapy) excessively affect the patients' quality of life. Relapses cannot be controlled by conventional or targeted treatments and are usually fatal. The strong heterogeneity of the disease (four subgroups and several subtypes) is related to innate or acquired resistance to reference treatments. Therefore, more efficient and less-toxic therapies are needed. Here, we demonstrated the efficacy of a novel inhibitor (C29) of CXCR1/2 receptors for ELR+CXCL cytokines for the treatment of childhood MB. The correlation between ELR+CXCL/CXCR1/2 expression and patient survival was determined using the R2: Genomics Analysis and Visualization platform. In vitro efficacy of C29 was evaluated by its ability to inhibit proliferation, migration, invasion, and pseudo-vessel formation of MB cell lines sensitive or resistant to radiotherapy. The growth of experimental MB obtained by MB spheroids on organotypic mouse cerebellar slices was also assayed. ELR+CXCL/CXCR1/2 levels correlated with shorter survival. C29 inhibited proliferation, clone formation, CXCL8/CXCR1/2-dependent migration, invasion, and pseudo-vessel formation by sensitive and radioresistant MB cells. C29 reduced experimental growth of MB in the ex vivo organotypic mouse model and crossed the blood-brain barrier. Targeting CXCR1/2 represents a promising therapeutic strategy for the treatment of paediatric MB in first-line treatment or after relapse following conventional therapy.

Abstract
OBJECTIVES Deepen our knowledge of the immune system alterations associated with obesity-related hypertension and demonstrate that polyunsaturated fatty acids can enhance the proliferation and their profile oxidant/antioxidant and subsequently involved in the strategy prevention and treatment in obese hypertensives. METHODS T cells are isolated from the blood of the control and obese women with hypertension the University Hospital of Tlemcen (Algeria), these cells are incubated in the presence of a synthetic mixture of PUFA to 30μM (DHA/EPA/LA) and stimulated by mitogens for 48hours. The cells are counted and used to assess intracellular oxidative status. The biochemical parameters are determined by the use of plasma. RESULTS In obese women with hypertension, a significant increase in plasma levels of (glucose, uric acid, creatinine, urea, total cholesterol and triglycerides) compared to controls. In addition, decreased cell proliferation, basal or stimulated by Con A was observed in obese women with hypertension compared with controls. The mixture of PUFA to 30μM reduced lymphoproliferation as well in obese women with hypertension than in controls. The rates in malondialdéhyde (MDA) and protein carbonyl lymphocytes are elevated in hypertensive obese women. PUFA supplementation to 30μM seems correct this redox status in hypertensive obese since rates in protein carbonyl, are similar to those of controls. CONCLUSION The mixture of PUFA (n-3 and n-6) can modulate the activity of T lymphocyte proliferation and correct the intracellular redox status in hypertensive obese women.
