Background

Polyinosinic:polycytidylic acid (poly I:C) is a synthetic double-stranded RNA that activates toll-like receptor 3 and retinoic acid inducible gene 1 (RIG-1)-like receptors, including RIG-1 and melanoma differentiation associated gene 5 [1].

In vitro: In the TLR3-transfected cells, Poly I:C stimulated the production of IL-8 in a dose-dependent manner [2]. Poly I:C liposome could directly suppress the growth of B16F10 melanoma in vitro and repeated peritumoral injections of Poly I:C liposome inhibited melanoma growth in a dose-dependent manner[3].

In vivo: Two days after implantation of a reticulum cell sarcoma, a lymphatic lymphoma, two leukemias, a fibrosarcoma, and a human adenovirus 12-induced tumor, treatment with polyinosinic polycytidylic-acid resulted in decreased growth rates of the tumors and increased survival times of the animals. In the reticulum cell sarcoma and the adenovirus 12-induced tumor, treatment with polyinosinic polycytidylic-acid caused a regression of the tumor after the tumor was grown to moderate size [4]. 3 h after an intraperitoneal injection of poly I:C (750 μg/kg), maximal fever of 1.6°C above baseline was observed. IL-1β and cyclooxygenase-2 mRNA were significantly upregulated in the hypothalamus of poly I:C-treated animals. Poly I:C decreased food intake by 30% [5]. Poly I:C inhibited chemically induced tumorigenesis in mouse skin [6].
