HSV-P10 construction and characterization. a Graphical representation of PTEN and PTENα coding sequences showing the mutations engineered in PTENα start codons to enhance translation of full-length PTENα. b–c Graphical representation of the DNA structure of wild-type F-strain HSV1 backbone showing doubly deleted γ34.5 genes, and gene-disrupting insertional ICP6 locus containing an enhanced green fluorescent protein (eGFP) gene with PTENα insertion (HSV-P10) or without PTENα (HSVQ). d PTENα production in infected tumor cell lysates over time. The indicated tumor cells were infected with HSV-P10 at MOI = 0.5 and harvested 0–12 hpi and probed for PTEN by western blot
