OBJECTIVE To generate an oncolytic herpes simplex virus (oHSV) permissive mouse melanoma cell line B16RHSV, preserving the tumorigenic ability in syngeneic mice. METHODS The herpes simplex virus entry mediator (HVEM) gene was amplified by PCR from human melanoma cell line A375, and cloned into pGEM-T Easy vector for sequencing. The HVEM gene was then cloned into pcDNA3 vector to generate pcDNA3-HVEM for transfection of mouse melanoma cell line B16-F10 cells. After that, the putative transfected cells were selected in full growth medium containing G418. The HVEM-expressing cells were isolated by immunomagnetic bead separation. The mouse melanoma cell line expressing oHSV receptor-HVEM, designated as B16RHSV, was generated. The permissibility of B16RHSV cells to oHSV infection was examined with green fluorescence protein (GFP)-expressing oHSV (oHSVGFP). To investigate the tumorigenic ability of both cells in vivo, 2×10(5) cells in 100 µl were subcutaneously inoculated into the right flanks of C57/BL mice. RESULTS In vitro, the B16RHSV mouse melanoma cells were shown by fluorescence microscopy capable of being infected by oHSVGFP. In vivo, the B16RHSV cells, like their wild type counterpart, grew to form melanoma in syngeneic mice. CONCLUSIONS A herpes simplex virus-permissive mouse melanoma cell line was established. Its tumorigenicity remained unchanged.

UI MeSH Term Description Entries
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D010957 Plasmids Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS. Episomes,Episome,Plasmid
D005260 Female Females
D005784 Gene Amplification A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication. Amplification, Gene
D005822 Genetic Vectors DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014162 Transfection The uptake of naked or purified DNA by CELLS, usually meaning the process as it occurs in eukaryotic cells. It is analogous to bacterial transformation (TRANSFORMATION, BACTERIAL) and both are routinely employed in GENE TRANSFER TECHNIQUES. Transfections
