    1. HEK293T packaging cellswere seeded at 30-40% confluency in 60 mm dishes. After 24 h, cells were co-transfected with three plasmids required for viral production i.e. VSV-G, psPAX2 (Addgene plasmid # 12260) and pLKO.1-puro-non-targeting and shIP6K1 clones using polyethyleniminereagent(PEI) and incubated at 37°C and 5% CO2 for virion formation. After 48 h, viral particles were harvested by collecting supernatant and filtered througha 0.45 μm syringe filter unit. Viral stock was aliquoted and stored at -80°C for further use. Viral titer was approximated on the number of cells plated for the production of lentivirus. Calculations were done as per Cell Bio Labs instruction. 2 x 106cells will yield 107infectious units/mL. All necessary precautions were taken while generating lentiviral particles such as wearing mask, double gloves, and sterile filter tips. All the consumables used were bleached (1% sodium hypochlorite solution) at least 1 h before being discarded
