MOLECULAR PROFILING REVEALS NOVEL GENE FUSIONS AND GENETIC MARKERS FOR REFINED PATIENT STRATIFICATION IN PEDIATRIC ACUTE LYMPHOBLASTIC LEUKEMIA.

Risk-adapted treatment protocols conferred remarkable improvement in the survival rates of pediatric acute lymphoblastic leukemia/lymphoma (ALL/LBL). Nevertheless, clinical management is still challenging in certain molecular subgroups and in the presence of alterations associated with an increased rate of relapse. In this study, disease-relevant genomic and transcriptomic profiles were established in a prospective, multicenter, real-world cohort involving 192 children diagnosed with ALL/LBL.

Sec20 is Required for Autophagic and Endocytic Degradation Independent of Golgi-ER Retrograde Transport.

Endocytosis and autophagy are evolutionarily conserved degradative processes in all eukaryotes. Both pathways converge to the lysosome where cargo is degraded. Improper lysosomal degradation is observed in many human pathologies, so its regulatory mechanisms are important to understand.

Vps8 overexpression inhibits HOPS-dependent trafficking routes by outcompeting Vps41/Lt.

Two related multisubunit tethering complexes promote endolysosomal trafficking in all eukaryotes: Rab5-binding CORVET that was suggested to transform into Rab7-binding HOPS. We have previously identified miniCORVET, containing Drosophila Vps8 and three shared core proteins, which are required for endosome maturation upstream of HOPS in highly endocytic cells (Lőrincz et al., 2016a).
