ome transcription factors take a chaperone to the nuclear dance. On page 469, Williams et al. show that STAT5A gets this escort from the ERBB4 receptor tyrosine kinase. ERBB4 becomes an escort upon activation by growth factors such as heregulin (HRG). The activated receptor is known to recruit and phos-phorylate STAT5A and get cleaved, thus releasing ERBB4's intracellular domain (4ICD). William...

Abstract AIMS • Design a novel in vitro model of sonic hedgehog (SHH) medulloblastoma (SHH-MB) by co-culture two distinct human SHH-MB cell lines with wild-type cerebellar organoids derived from induced pluripotent stem cells. Investigate how the phenotype cells grown differs conventional monolayer or tumour spheroid cultures. METHOD DAOY and ONS76 were cultured as monolayers, spheroids co-cult...

The neuregulin/ErbB signaling network is genetically associated with schizophrenia and modulates hippocampal γ oscillations--a type of neuronal network activity important for higher brain processes and altered in psychiatric disorders. Because neuregulin-1 (NRG-1) dramatically increases extracellular dopamine levels in the hippocampus, we investigated the relationship between NRG/ErbB and dopam...

Prostate cancer is one of the most commonly diagnosed male malignancies. Genome wide association studies have revealed HNF1b to be a major risk gene for prostate cancer susceptibility. We examined the mechanisms of involvement of HNF1b in prostate cancer development. We integrated data from Gene Expression Omnibus prostate cancer genes from the Dragon Database of Genes Implicated in Prostate Ca...

Ewing Sarcoma is an aggressive, oncofusion-driven, malignant neoplasm of bone and soft tissue affecting predominantly children and young adults. Seeking to identify potential novel therapeutic targets/agents for this disease, our previous studies uncovered microRNAs regulated by EWS/Fli1, the most common oncofusion, with growth modulatory properties. In the present study, we sought to identify ...

Interactions between short modified peptide motifs and modular protein domains are central events in cell signal-transduction. We determined interaction partners to all cytosolic tyrosine residues of the four members of the ErbB-receptor family in an unbiased fashion by quantitative proteomics using pull-down experiments with pairs of phosphorylated and nonphosphorylated synthetic peptides. Eac...

The GABAA receptor beta subunit is required to confer sensitivity to gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the CNS. In previous studies we demonstrated that the growth and differentiation factor neuregulin 1 (NRG1) selectively induced expression of the beta2 subunit mRNA and encoded protein in rat cerebellar granule neurons in culture. In the present report we...

Cervical small cell neuroendocrine tumors (CSCNETs) are rare, aggressive neuroendocrine tumors (NETs). Reliable diagnostic and prognostic CSCNET markers are lacking, making diagnosis and prognosis prediction difficult, and treatment strategies limited. Here we provide mutation profiles for five tumor-normal paired CSCNETs using whole exome sequencing (WES). We expanded our assessment of frequen...
