TL;DR: This study provides additional evidence that CRT should be delayed for young patients and identifies the potential benefits of reducing radiation dose to normal brain.
Abstract: Purpose We conducted a prospective trial to evaluate late effects in pediatric patients with low-grade glioma (LGG) treated with conformal radiation therapy (CRT). Patients and Methods Between August 1997 and August 2006, 78 pediatric patients with LGG (mean age, 9.7 years; standard deviation, ±4.4 years) received 54 Gy of CRT with a 10-mm clinical target volume margin. Tumor locations were diencephalon (n = 58), cerebral hemisphere (n = 3), and cerebellum (n = 17). Baseline and serial evaluations were performed to identify deficits in cognition, endocrine function, and hearing. Deficits were correlated with clinical factors and radiation dose within specific normal tissue volumes. Results Cognitive effects of CRT through 5 years after CRT correlated with patient age, neurofibromatosis type 1 status, tumor location and volume, extent of resection, and radiation dose. The effect of age exceeded that of radiation dose; patients younger than 5 years experienced the greatest decline in cognition. Before CRT, ...

TL;DR: It is demonstrated that ABCB6 is uniquely located in the outer mitochondrial membrane and is required for mitochondrial porphyrin uptake and is challenging previous assumptions about the intracellular movement of porphyrs and the factors controlling haem biosynthesis.
Abstract: The transport of porphyrins across the mitochondrial membrane is important for cellular processes. The ABC transporter Abcb6 (an energy-requiring transporter) plays a key role not only in mitochondrial porphyrin transport but also in the upregulation of haeme biosynthesis. The movement of anionic porphyrins (for example, haem) across intracellular membranes is crucial to many biological processes, but their mitochondrial translocation and coordination with haem biosynthesis is not understood. Transport of porphyrins into isolated mitochondria is energy-dependent1,2,3, as expected for the movement of anions into a negatively charged environment. ATP-binding cassette transporters actively facilitate the transmembrane movement of substances. We found that the mitochondrial ATP-binding cassette transporter ABCB6 is upregulated (messenger RNA and protein in human and mouse cells) by elevation of cellular porphyrins and postulated that ABCB6 has a function in porphyrin transport. We also predicted that ABCB6 is functionally linked to haem biosynthesis, because its mRNA is found in both human bone marrow and CD71+ early erythroid cells (by database searching), and because our results show that ABCB6 is highly expressed in human fetal liver, and Abcb6 in mouse embryonic liver. Here we demonstrate that ABCB6 is uniquely located in the outer mitochondrial membrane and is required for mitochondrial porphyrin uptake. After ABCB6 is upregulated in response to increased intracellular porphyrin, mitochondrial porphyrin uptake activates de novo porphyrin biosynthesis. This process is blocked when the Abcb6 gene is silenced. Our results challenge previous assumptions about the intracellular movement of porphyrins and the factors controlling haem biosynthesis.

TL;DR: This work shows that the nuclear factor HLA-B-associated transcript 3 (BAT3) was released from tumor cells, bound directly toNKp30, and engaged NKp30 on NK cells, and proposes a concept for target cell recognition by NK cells beyond "missing self" and "induced self," mediated through a tumor cell-derived extracellular factor.

TL;DR: It is shown that Cdk inhibition and p27 stability are regulated through direct phosphorylation by tyrosine kinases, which may provide an explanation for Cdk kinase activities observed in p27 complexes and for premature p27 elimination in cells that have been transformed by activated tyrosin kinases.
