The three plasmid systems, including target gene plasmid (pAAV-CAG-mCherry), capsid plasmid (pAAV-6, pAAV-1, pAAV-7m8, pAAV-7, pAAV-8, pAAV-10) and helper plasmid (pHelper), were all purchased from Fenghui Biotechnology (Hunan, China). The complementary DNA (cDNA) encoding the mouse PTEN gene was synthesized from GENEWIZ (Suzhou, China). pAAV-CAG-PTEN was obtained by replacing mCherry gene in pAAV-CAG-mCherry with PTEN gene. Reverse the PTEN gene sequence in pAAV-CAG-PTEN to get pAAV-CAG-PTEN
