HSPA5 and neoplasm: Remarkably, in sharp contrast, at day 27 post‐tumor cell implantation, expression of the tumor Luc in mice receiving combination of RGD4C/AAVP‐Grp78‐HSVtk/GCV and TMZ was dramatically reduced than the initial Luc signal recorded on day 9, showing not only a lack of tumor growth but a substantial reduction in tumor size and tumor viability (Fig 4A–C).
