RESUMEN
OBJECTIVE: To construct a lentiviral expression vector of the PIAS-NY gene, and establish a mouse spermatocyte-derived cell line with a stable overexpression of PIAS-NY. METHODS: PIAS-NY was synthesized, amplified by PCR and cloned into the lentiviral vector expression plasmid pGC-FU. After digestion and sequencing, pGC-FU-PIAS-NY, pHelper 1.0 and pHelper 2.0 were co-transfected into 293T cells. Then the lentiviral particles were used to transfect the mouse spermatocyte-derived cells. The expression of the PIAS-NY protein was detected by Western blot. RESULTS: We successfully constructed the lentiviral expression vector pGC-FU-PIAS-NY and established a mouse spermatocyte-derived cell line with a stable overexpression of PIAS-NY. CONCLUSION: The construction of the lentiviral expression vector pGC-FU-PIAS-NY and the obtainment of stably transfected mouse spermatocyte-derived cells have paved the way for further studies on the roles of the PIAS-NY gene in spermatogenesis.
