Murine mammary FM3A carcinoma cells transformed with the herpes simplex virus type 1 thymidine kinase gene are highly sensitive to the growth‐inhibitory properties of (E)‐5‐(2‐bromovinyl)‐2'‐deoxyuridine and related compounds

摘要

>Murine mammary carcinoma (FM3A TK−/HSV-1 TK+) cells, which are thymidine kinase (TK)-deficient but have been transformed with the herpes simplex virus type 1 (HSV-1) TK gene are inhibited in their growth by (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU), (E)-5-(2-iodovinyl)-2'-deoxyuridine (IVDU) and (E)-5-(2-bromovinyl)-2'-deoxycytidine (BVDC) at 0.5, 0.5 and 0.8 data-equation-construct="true" class="math-equation-construct"> data-equation-image="true" class="math-equation-image"> alt="math formula" src="http://onlinelibrary.wiley.com/store/10.1016/0014-5793(85)80747-X/asset/equation/feb2001457938580747x-math-si1.gif?v=1&s=f150101d4947ab4141af4a14aaea905d556d36a8" class="inlineGraphic" /> data-equation-mathml="true" class="math-equation-mathml" style="display:none">, respectively; i.e., a concentration 5000 to 20000-fold lower than that required to inhibit the growth of the corresponding wild-type FM3A/0 cells. Hence, transformation of tumor cells with the HSV-1 TK gene makes them particularly sensitive to the cytostatic action ofBVDU and related compounds.
