SNP array profiling of childhood adrenocortical tumors reveals distinct pathways of tumorigenesis and highlights candidate driver genes

Childhood adrenocortical tumors (ACT) are rare malignancies, except in southern Brazil, where a higher incidence rate is associated to a high frequency of the founder R337H TP53 mutation. To date, copy number alterations in these tumors have only been analyzed by low-resolution comparative genomic hybridization.

Frederiksenia canicola gen. nov., sp. nov. isolated from dogs and human dog-bite wounds.

Polyphasic analysis was done on 24 strains of Bisgaard taxon 16 from five European countries and mainly isolated from dogs and human dog-bite wounds. The isolates represented a phenotypically and genetically homogenous group within the family Pasteurellaceae. Their phenotypic profile was similar to members of the genus Pasteurella. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry clearly identified taxon 16 and separated it from all other genera of Pasteurellaceae showing a characteristic peak combination. Taxon 16 can be further separated and identified by a RecN protein signature sequence detectable by a specific PCR. In all phylogenetic analyses based on 16S rRNA, rpoB, infB and recN genes, taxon 16 formed a monophyletic branch with intraspecies sequence similarity of at least 99.1, 90.8, 96.8 and 97.2 %, respectively. Taxon 16 showed closest genetic relationship with Bibersteinia trehalosi as to the 16S rRNA gene (95.9 %), the rpoB (89.8 %) and the recN (74.4 %), and with Actinobacillus lignieresii for infB (84.9 %). Predicted genome similarity values based on the recN gene sequences between taxon 16 isolates and the type strains of known genera of Pasteurellaceae were below the genus level. Major whole cell fatty acids for the strain HPA 21(T) are C14:0, C16:0, C18:0 and C16:1 ω7c/C15:0 iso 2OH. Major respiratory quinones are menaquinone-8, ubiquinone-8 and demethylmenaquinone-8. We propose to classify these organisms as a novel genus and species within the family of Pasteurellaceae named Frederiksenia canicola gen. nov., sp. nov. The type strain is HPA 21(T) (= CCUG 62410(T) = DSM 25797(T)).
