Abstract:
OBJECTIVETo detect gene mutations of p53 gene (exon 4-6) in fibroblasts.
METHODSSamples of keloids were taken from 15 patients. The mutations of p53 gene were detected using polymerase chain reaction, the single-strand conformational polymorphism(SSCP) analysis and DNA sequencing.
RESULTSGene mutations in p53 gene exon 4, 5, and 6 were identified in all the patients with keloids.
CONCLUSIONGene mutations resulted in keloid p53 protein losing its functions of suppressing cell processes and conducting apoptosis.
