In addition, mitochondria lack more advanced repair pathways, such as nucleotide excision repair and homologous recombination, which makes mtDNA particularly susceptible to the accumulation of mutations [35], which leads to a higher rate of damaged mtDNA in mitochondria and further aggravates oocyte damage
GHK-Cu (Copper Peptide): Known for its exceptional skin-regenerating properties, GHK-Cu stimulates collagen and elastin synthesis
The three libraries were generated using error-prone PCR as described above, using the following conditions to produce varying levels of mutagenesis: Library 1: 30 M 8-oxo-dGTP, 1 M dPTP, 20 PCR cycles Library 2: 20 M 8-oxo-dGTP, 2 M dPTP, 20 PCR cycles Library 3: 10 M 8-oxo-dGTP, 3 M dPTP, 20 PCR cycles The library sizes (approximated by number of transformants as described above) were 6 10 7 for each library
