Abstract: An oncolytic herpes simplex virus (oHSV) has proven amenable in oncolytic virotherapy and was approved to treat melanoma. The immediate-early (IE) protein ICP27 encoded by gene UL54 is essential for HSV infection. Post-transcriptional modification of UL54 would increase tumor targeting of oHSVs. However, UL54 gene transcription regulatory sequences and factors were not reported yet. Here we isolated a new strain LXMW of type 1 HSV (HSV-1-LXMW) in China and found it's closely related to HSV-1 strains Patton and H129 in the US by the first and next generation DNA sequencing viral DNA phylogenetic analysis. Using a weight matrix-based program Match, we found the UL54 transcription regulatory sequences binding to the transcription factors Oct-1, v-Myb and Pax-6 in HSV-1-LXMW, while the sequences binding to Oct-1 and Hairy in a HSV-2 strain. Further validation showed that HSV-1 and HSV-2 shared the common sequence binding to Oct-1, but had unique sequences to bind v-Myb and Pax-6, or Hairy, respectively, by DNA sequence alignment of total 11 HSV strains. The published results howed that the expression of transcription factors is consistent with the tissue tropism of HSV-1 and HSV-2. In the current article a new HSV-1 strain LXMW was isolated and its putative HSV UL54 transcription regulatory sequences and factors were identified for the first time. Our findings highlight the new understanding of the principles of transcriptional regulation in HSV biology and oncolytic virotherapy. © 2018 Ivyspring International Publisher.
