1. [RETRACTED ARTICLE] Ginsenoside Rd inhibits IL-1β-induced inflammation and degradation of intervertebral disc chondrocytes by increasing IL1RAP ubiquitination
Many compounds of ginsenosides show anti-inflammatory properties. However, their anti-inflammatory effects in intervertebral chondrocytes in the presence of inflammatory factors have never been shown. Increased levels of pro-inflammatory cytokines are generally associated with the degradation and death of chondrocytes; therefore, finding an effective and non

2. E3 ubiquitin ligase Cbl-b potentiates the apoptotic action of arsenic trioxide by inhibiting the PI3K/Akt pathway
Arsenic trioxide (ATO) is a strong inducer of apoptosis in malignant hematological cells. Inducible phosphatidyl inositol 3 kinase (PI3K)-Akt activation promotes resistance to ATO. In the present study, we evaluated whether E3 ubiquitin ligase Cbl-b, a negative regulator of PI3K activation, is involved in the action of ATO. The effect of ATO on cell viabilit

3. Vias de sinalização de estresses em plantas : análise da região promotora do gene NIMIN-1 de Arabidopsis thaliana e da proteína ScCBL1 de cana-de-açúcar (Saccharum spp.) / Signal transductional pathways under biotic and abiotic stress in plants : functional analysis of NIMIN-1 promoter region in Arabidopsis and characterization of a calcium binding protein (ScCBL1) in sugar cane Saccharum spp.)
Estresses bióticos e abióticos como a seca, salinidade e ataque por patógenos são responsáveis por perdas significantes em culturas de grãos ao redor do mundo. Diversos genes são regulados em resposta a esses fatores e podem ser ativados ou reprimidos para gerar uma resposta específica na planta de maneira a gerar uma resposta de defesa que atenue os

4. The truncation that generated the v-cbl oncogene reveals an ability for nuclear transport, DNA binding and acute transformation.
The v-cbl oncogene is the transforming gene of the murine Cas NS-1 retrovirus which induces pre-B cell lymphomas and myeloid leukaemias. Sequencing of c-cbl has revealed that v-cbl was generated by a large truncation that removed 60% of the C-terminus of the corresponding protein. In this study we prepared antibodies to cbl and found that c-cbl encodes a 120

5. Recognition of two intracellular cobalamin binding proteins and their identification as methylmalonyl-CoA mutase and methionine synthetase.
The granulocyte R-type cobalamin binding protein delivers cobalamin (Cbl) exclusively to hepatocytes, and transcobalamin II delivers Cbl to various mammalian cells. Both protein-Cbl complexes enter cells by pinocytosis, and the protein moieties are rapidly degraded in lysosomes. The liberated Cbl is subsequently bound to a high-molecular-weight intracellular

6. Correction of Cobalamin Malabsorption in Pancreatic Insufficiency with a Cobalamin Analogue that Binds with High Affinity to R Protein but not to Intrinsic Factor: IN VIVO EVIDENCE THAT A FAILURE TO PARTIALLY DEGRADE R PROTEIN IS RESPONSIBLE FOR COBALAMIN MALABSORPTION IN PANCREATIC INSUFFICIENCY
In vitro studies indicate that [57Co]cobalamin (Cbl) is preferentially bound to salivary R protein as opposed to intrinsic factor (IF) and that [57Co]Cbl bound to R protein is not transferred to IF at either pH 2 or pH 8. Incubation of R protein-[57Co]Cbl with pancreatic proteases causes a partial degradation of the R protein moiety and a rapid transfer of [

7. The c-cbl proto-oncogene is preferentially expressed in thymus and testis tissue and encodes a nuclear protein.
Cas NS-1 is an acutely transforming murine retrovirus that induces early B-lineage lymphomas and occasional myeloid leukemias. The transforming sequence of this virus, v-cbl, shows no homology to known oncogenes but has some similarities to the yeast transcriptional factor GCN4. In this study we used a v-cbl probe to analyze mRNAs from a wide range of murine

8. Tissue Hyperplasia and Enhanced T-Cell Signalling via ZAP-70 in c-Cbl-Deficient Mice
The c-Cbl protein is tyrosine phosphorylated and forms complexes with a wide range of signalling partners in response to various growth factors. How c-Cbl interacts with proteins, such as Grb2, phosphatidylinositol 3-kinase, and phosphorylated receptors, is well understood, but its role in these complexes is unclear. Recently, the Caenorhabditis elegans Cbl

9. APS Facilitates c-Cbl Tyrosine Phosphorylation and GLUT4 Translocation in Response to Insulin in 3T3-L1 Adipocytes
APS is a Cbl-binding protein that is tyrosine phosphorylated by the insulin receptor kinase. Insulin-stimulated phosphorylation of tyrosine 618 in APS is necessary for its association with c-Cbl and the subsequent tyrosine phosphorylation of Cbl by the insulin receptor in both 3T3-L1 adipocytes and CHO-IR cells. When overexpressed in these cells, wild-type A

10. A Gibberellin-Regulated Calcineurin B in Rice Localizes to the Tonoplast and Is Implicated in Vacuole Function1
Many developmental and environmental signals are transduced through changes in intracellular calcium concentrations, yet only a few calcium-binding proteins have been identified in plants. Calcineurin B-like (CBL) proteins are calcium-binding proteins that are thought to function as plant signal transduction elements. RNA profiling using a rice (Oryza sativa

11. Effect of Proteolytic Enzymes on the Binding of Cobalamin to R Protein and Intrinsic Factor: IN VITRO EVIDENCE THAT A FAILURE TO PARTIALLY DEGRADER PROTEIN IS RESPONSIBLE FOR COBALAMIN MALABSORPTION IN PANCREATIC INSUFFICIENCY
Cobalamin (Cbl; vitamin B12) malabsorption in pancreatic insufficiency can be partially corrected by bicarbonate and completely corrected by pancreatic proteases but the mechanisms involved are unknown. Because saliva contains enough R-type Cbl-binding protein (R protein) to bind all of the dietary and biliary Cbl, it is possible that R protein acts as an in

12. Altered thymic positive selection and intracellular signals in Cbl-deficient mice
Cbl is the product of the protooncogene c-cbl and is involved in T cell antigen receptor (TCR)-mediated signaling. To understand the role of Cbl for immune system development and function, we generated a Cbl-deficient mouse strain. In Cbl-deficient mice, positive selection of the thymocytes expressing major histocompatibility complex class II-restricted tran
