Sprouty2 Regulates Endocytosis and Degradation of Fibroblast Growth Factor Receptor 1 in Glioblastoma Cells.

The Sprouty (SPRY) proteins are evolutionary conserved modulators of receptor tyrosine kinase (RTK) signaling. SPRY2 inhibits fibroblast growth factor (FGF) signaling, whereas it enhances epidermal growth factor (EGF) signaling through inhibition of EGF receptor (EGFR) endocytosis, ubiquitination, and degradation. In this study, we analyzed the effects of SPRY2 on endocytosis and degradation of FGF receptor 1 (FGFR1) using two human glioblastoma (GBM) cell lines with different endogenous SPRY2 levels.

Prophylaxis with enoxaparin and antithrombin III in drug-induced coagulation alterations in childhood leukemia: a retrospective experience of 20 years.

Background: Thromboembolic complications are well known in the treatment of childhood acute lymphoblastic leukemia. Over the years it has not been possible to reach a consensus on a possible prophylaxis of thromboembolic events during intensive therapy. Only the administration of enoxaparin was able to achieve evidence in the literature to date.

Recommendations for Nutritional Supplementation in Pediatric Oncology: A Compilation of the Facts.

Background: As one of the few modifiable risk factors, the importance of dietary patterns for both disease prevention and treatment outcome in pediatric oncology has gained increasing popularity. Malnutrition is associated with lower survival rates, tolerance to treatment, and quality of life. Yet, especially in children with malignancies, nutritional deterioration is common, and pediatric cancer patients often present with inadequate intake of micro- and macronutrients alike.

Supportive methods for childhood acute lymphoblastic leukemia then and now: A compilation for clinical practice.

Survival of childhood acute lymphoblastic leukemia has significantly improved over the past decades. In the early years of chemotherapeutic development, improvement in survival rates could be attained only by increasing the cytostatic dose, also by modulation of the frequency and combination of chemotherapeutic agents associated with severe short- and long-time side-effects and toxicity in a developing child's organism. Years later, new treatment options have yielded promising results through targeted immune and molecular drugs, especially in relapsed and refractory leukemia, and are continuously added to conventional therapy or even replace first-line treatment.

Tackling resistance in chronic myeloid leukemia: Novel cell death modulators with improved efficacy.

The development of resistance poses a serious problem in the therapy of cancer due to the necessity of a multiple-drug and unlimited treatment of affected patients. In chronic myeloid leukemia (CML), the introduction of imatinib has revolutionized the therapy. The persistence of an untreatable cancer stem cell pool and other resistance-causing factors, however, also impede the cure of this malignancy.
