Dopamine D(2) and D(3) receptors are similar subtypes with distinct interactions with arrestins; the D(3) receptor mediates less agonist-induced translocation of arrestins than the D(2) receptor. The goals of this study were to compare nonphosphorylated arrestin-binding determinants in the second intracellular domain (IC2) of the D(2) and D(3) receptors to identify residues that contribute to t...
We provide data on fetal growth pattern on the molecular subtypes of Beckwith-Wiedemann syndrome (BWS): IC1 gain of methylation (IC1-GoM), IC2 loss of methylation (IC2-LoM), 11p15.5 paternal uniparental disomy (UPD), and CDKN1C mutation. In this observational study, gestational ages and neonatal growth parameters of 247 BWS patients were compared by calculating gestational age-corrected standar...
A large cluster of imprinted genes is located on the mouse distal chromosome 7. This cluster is well conserved in humans and its dysregulation results in the overgrowth- and tumour-associated Beckwith-Wiedemann syndrome. Two imprinting centres (IC1 and IC2) controlling different sets of genes have been identified in the cluster, raising the hypothesis that the cluster is divided into two functi...
Neurofibromatosis type 1 (NF1) tumor suppressor gene product, neurofibromin, functions in part as a Ras-GAP, and though its loss is implicated in the neuronal abnormality of NF1 patients, its precise cellular function remains unclear. To study the molecular mechanism of NF1 pathogenesis, we prepared NF1 gene knockdown (KD) PC12 cells, as a NF1 disease model, and analyzed their molecular (gene a...
BACKGROUND In flagella, the outer dynein arm (ODA) and inner dynein arm (IDA) play distinct roles in generating beating motion. However, functional communications between the two dyneins have not been investigated. RESULTS Here, we demonstrated by cryo-electron microscopy and chemical crosslinking that intermediate chain 2 (IC2) of ODAs interacts with the dynein regulatory complex in the axon...
The distal end of mouse chromosome 7 (Chr 7) contains a large cluster of imprinted genes. In this region two cis-acting imprinting centers, IC1 (H19 DMR) and IC2 (KvDMR1), define proximal and distal subdomains, respectively. To assess the functional independence of IC1 in the context of Chr 7, we developed a recombinase-mediated chromosome truncation strategy in embryonic stem cells and generat...
The murine W and Steel loci encode the Kit receptor tyrosine kinase and its ligand, Steel factor, respectively. Loss of function mutations at either the W or Sl loci lead to a variety of pleiotropic developmental defects, including mast cell deficiency and severe macrocytic anemia. In addition to these loss-of-function mutations, gain-of-function mutations in c-kit, leading to constitutive acti...
Peptide mimics of intracellular loop 2 (ic2) of the human 5HT1a receptor have been studied with respect to their ability to inhibit agonist binding via interference with receptor-G-protein coupling. These peptides give shallow concentration-effect relationships. Additionally, these peptides have been studied with respect to their ability to trigger the signal transduction system of this Gi-coup...
Abstract Rare studies of cocrystal engineering have focused on improving carrier mobility organic semiconductors mainly because the generation ambipolarity, alteration charge polarity or reduction electronic couplings. Herein, we utilize indolo[2,3‐a]carbazole (IC) as model compound and 2,6‐diphenylanthraquinone (DPAO) 9‐fluorenone (FO) coformers to construct IC2‐DPAO IC‐FO cocrystals with 2 : ...
Platinum-based chemotherapy is the standard of care in metastatic bladder cancer. With the approval of various checkpoint inhibitors, immunotherapy has revolutionized the traditional treatment modalities. The aim of the study was to evaluate whether PD-L1 expression on tumor cells (TCs) and tumor-infiltrating immune cells (ICs) can be used as biomarker to predict recurrence-free survival (RFS),...
