Abstract
Methods of treating a cancer in a patient are provided. The methods can include obtaining a tumor sample from a patient, detecting whether CCNG1 gene expression is present in the tumor sample, diagnosing the patient with a CCNG1 inhibitor-responsive cancer when the presence of CCNG1 gene expression in the tumor sample is detected, and/or administering an effective amount of a CCNG1 inhibitor to the diagnosed patient. CCNG1 inhibitors can include a viral vector having a binding peptide that is configured to bind one or more signature (SIG) elements of an invading tumor and at least one cytocidal gene. CCNG1 inhibitors including cell penetrating peptides are also provided.
Claims12
A therapeutic comprising a viral vector encoding an inhibitor of cyclin G1 activity and at least one cytocidal gene selected from the group consisting of a gene encoding a pro-drug activating system, a herpes simplex virus thymidine kinase (HSV-tk) gene, an apoptosis-inducing gene, a gene encoding an inhibitory RNA, and a gene encoding an antisense RNA, wherein the viral vector displays a signature (SIG) element binding peptide on its surface, wherein the SIG element binding peptide binds a Gly-Xxx-Pro/Hyp-Ala-Xxx-Pro/Hyp (SEQ ID NO:
- 3) polypeptide.
A method of treating a cancer that expresses CCNG1 in an individual, comprising administering to the individual a therapeutic comprising a viral vector encoding at least two cytocidal genes comprising an inhibitor of cyclin G1 activity and a herpes simplex virus thymidine kinase (HSV-tk) gene.
