    Antikeratin autoantibodies in the amyloid deposits of lichen amyloidosus and macular amyloidosis (1989)

    Notes: Summary In order to characterize immunoglobulins found on amyloid deposits of lichen amyloidosus and macular amyloidosis, an elution from cryostat sections was performed with citrate buffer, glycine buffer, NaCl, and PBS. Resulting eluates (mainly IgG) were examined with dot immunoblotting and SDS-PAGE immunoblotting and were found to react with the human epidermal keratin of 50 and 67 kD. Antikeratin autoantibody activities in normal murine and human sera were examined using a dot immunoblotting assay. In murine sera, titers of IgG and IgM autoantibodies were higher in older mice. The human cord blood showed significantly lower IgM autoantibody titers, whereas IgG antibody titers showed no significant differences from adults' sera, probably due to the permeability of IgG through the placental barrier. A stronger antibody activity in older individuals was thought to be due to the repeated exposures to keratin proteins derived from apoptotic keratinocytes. Sera from lichen amyloidosus and macular amyloidosis patients did not show any difference from normal controls in their antikeratin titers. It was concluded that the patients with lichenoid or macular amyloidosis are capable of producing a normal level of antikeratin autoantibodies. However, the removal of opsonized keratin-type amyloid from the skin is slow or deficient due to as yet unknown factors.

    Notes: Abstract The Borg (binder of Rho GTPases) family proteins interact with CDC42 and TC10 in a guanosine triphosphate (GTP)-dependent manner. We have isolated a full-length cDNA of the mouse Borg4 gene, which is a member of this family. Sequence analysis revealed that this gene encoded a putative 349-amino acid protein. By reverse transcription — coupled polymerase chain reaction (RT-PCR) analysis, we observed that Borg4 was expressed ubiquitously in adult tissues. Additionally, we determined the entire cDNA sequence of the putative human Borg4 orthologue. By fluorescence in situ hybridization, mouse Borg4 and the putative human orthologue have been assigned to mouse chromosome 11E and human chromosome 17q24–25, which has been described as syntenic to the mouse region.
