Abstrakt: Cervical cancer, often driven by high-risk human papillomavirus (HPV) infections such as HPV16 or HPV18, remains a leading cause of cancer-related deaths. HPV16, found in about 90% of cervical cancer patients, harbors key oncogenic related genes (E6, E7, E2, E5) and an upstream regulatory region (URR) that contribute to cancer progression. This study introduces a novel approach using a recombinant oncolytic herpes simplex virus type 1 (HSV-1) named SONC103, armed with a CRISPR/Cas9 gene editing system. The aim was to target and disrupt integrated HPV16 genes in cervical cancer cells. Results demonstrated SONC103's capability to specifically and effectively knock down HPV16 oncogenes, thereby reducing cell proliferation and promoting apoptosis. Analyses further revealed loss of HPV16 DNA probes in infected cells' chromosomes, significant regulation of cellular processes related to tumor apoptosis, and downregulation of E6/E7 oncoproteins while increasing tumor suppressor proteins P53 and pRB. Notably, SONC103 exhibited substantial inhibition of tumor growth in a murine xenograft cervical cancer model. This study showcases the potential of the recombinant oncolytic HSV-1 virus (SONC103) in combating HPV16-positive cervical cancer by targeting oncogenes and facilitating oncolysis.
