Genome resequencing and bioinformatic analysis of SNP containing candidate genes in the autoimmune vitiligo Smyth line chicken model.

Background: The Smyth line (SL) chicken is the only animal model for autoimmune vitiligo that spontaneously displays all clinical and biological manifestations of the human disorder. To understand the genetic components underlying the susceptibility to develop SL vitiligo (SLV), whole genome resequencing analysis was performed in SLV chickens compared with non-vitiliginous parental Brown line (BL) chickens, which maintain a very low incidence rate of vitiligo.

Results: Illumina sequencing technology and reference based assembly on Red Jungle Fowl genome sequences were used.

Establishment of an immortal chicken embryo liver-derived cell line.

A continuously growing immortal cell substrate can be used for virus propagation, diagnostic purposes, and vaccine production. The aim of this study was to develop an immortal chicken cell line for efficient propagation of avian infectious viruses. From the various chicken embryo cells that were tested for life span extension, an immortalized chicken embryo liver (CEL) cell line, named CEL-im, was derived spontaneously without either oncogenic viruses or carcinogenic chemical treatment.
