ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationships between skin photoaging and point mutations in mitochondrial DNA (mtDNA) control region for replication of dermal fibroblast.</p><p><b>METHODS</b>Cultured dermal fibroblasts were treated by 8-methoxypsora len /ultraviolet A (8-MOP/UVA). mtDNA was extracted by one-step-method and th e PCR products of D-loop and adjacent transcription promoter (DLP(6)) fragment of mtDNA control region for replication were detected by polymerase chain reaction-single strain conformation polymorphism and direct sequencing.</p><p><b>RESULTS</b>After treated by 8-MOP/UVA, point mutations of 414 T-->G of DLP(6) fragment of mtDNA control region for replication largely accumulated.</p><p><b>CONCLUSION</b>Accumulation of point mutations of DLP(6) fragment of mtDNA control region for replication may be closely associated with skin photoaging.</p>
