| Outline of Final Research Achievements |
The aims of this study were to confirm a molecular basis on utilization of age-estimation markers for forensic individualization; (1) Age-dependent M-LP gene, previously identified, is involved in the maintenance of mtDNA, thereby protects cells from mitochondrial dysfunction. (2) Expression of human M-LP is partly regulated by human homolog of Rhit identified in mice. (3) Among non-synonymous SNPs in the human Rhit gene there are several ones producing loss-of-function. (4) Rhit-knockout mice exhibited no unique phenotype, and no inverse relationship between the human Rhit and M-LP mRNA levels in various human tissues. These findings allow us to postulate that the Rhit might be functionally complemented by other factor(s). (5)Simple genotyping method that has considerable potential for screening of trait-related CNVs useful for forensic casework was developed. (6) Functional SNPs, possibly served as genetic risk factor for autoimmunity, in the human DNase family genes were identified.
