Five feline-derived microsatellite markers were genotyped in a large pedigree of cats that segregates for ventral white spotting. Both KIT and EDNRB cause similar white spotting phenotypes in other species. Thus, three of the five microsatellite markers chosen were on feline chromosome B1 in close proximity to KIT; the other two markers were on feline chromosome A1 near EDNRB. Pairwise linkage ...
Abstract Pediatric patients with advanced relapsed/refractory (R/R) solid (including central nervous system [CNS]) tumors have poor prognoses. KIT alterations are common in germ cell and high-grade glioma (HGG); platelet-derived growth factor receptor alpha (PDGFRA) sarcoma HGG. Diffuse midline gliomas H3K27-altered (DMG-H3K27-altered) depend on PDGFRA signaling for tumor growth. However, no KI...
Imatinib mesylate is a tyrosine kinase inhibitor of c-KIT and PDGFRA. Imatinib mesylate is an effective drug that can be used as a first-choice agent for treatment of GISTs. Prior to treatment, molecular diagnosis of c-KIT or PDGFRA is necessary; however, in some types of GISTs, it is impossible to obtain a sufficient amount of specimen for diagnosis. An inoperable or marginally resectable GIST...
Therapeutically validated oncoproteins in myeloproliferative neoplasms (MPN) include BCR-ABL1 and rearranged PDGFR proteins. The latter are products of intra- (e.g. FIP1L1-PDGFRA) or inter-chromosomal (e.g. ETV6-PDGFRB) gene fusions. BCR-ABL1 is associated with chronic myelogenous leukaemia (CML) and mutant PDGFR with an MPN phenotype characterized by eosinophilia and in addition, in case of FI...
Oligodendrocytes have been considered as a functionally homogeneous population in the central nervous system (CNS). We performed single-cell RNA sequencing on 5072 cells of the oligodendrocyte lineage from 10 regions of the mouse juvenile and adult CNS. Thirteen distinct populations were identified, 12 of which represent a continuum from Pdgfra(+) oligodendrocyte precursor cells (OPCs) to disti...
Eosinophil-associated conditions, such as asthma and eosinophilic bronchitis, have been associated with chronic persistent cough, usually responding to corticosteroid therapy. This case study reports a case of persistent cough associated with gastro-oesophageal reflux (GOR) and hypereosinophilia. Treatment of GOR with proton pump inhibitors and fundoplication did not control the cough. However,...
To evaluate the frequency of clonal abnormalities in patients with unexplained persisting eosinophilia we analyzed 40 patients (27 males, 13 females) using cytomorphology, cytogenetic analysis, interphase fluorescence in situ hybridization (FISH), and reverse transcriptase polymerase chain reaction (RT-PCR). Cytogenetic analysis revealed clonal abnormalities in five patients (four of whom were ...
