Biological Activity
| ln Vitro | The paracellular permeability of immortalized airway epithelial cells is increased at a dose and time by polyinosinic-polycytidylic acid (0.5–5 μg/mL, 3–24 h) [4]. 16HBE14o- cells experience disruption of their epithelial apical junction complexes and tight junctions when exposed to polyinosinic-polycytidylic acid (5 μg/mL, 6 h) [4]. However, the acid does not cause any cytotoxicity to 16HBE14o- cells [4]. |
| ln Vivo | Polyinosinic acid (2.5-10 mg/mL, stereotactic injection, single dosage) causes prolonged reactive reactions in the substantia nigra and dorsal striatum [2]. Polyinosinic-polycytidylic Acid (10 μg/mouse, i.p.) Polyinosinic-polycytidylic Acid (1.25 mg/kg, i.p., single dosage) boosts brain tumor lung growth via TLR3 and TLR4/MyD88 signaling in the MCAO model [3 ]. |
| Cell Assay |
Cell Cytotoxicity Assay[4] Cell Types: 16HBE14o- Cell Tested Concentrations: 5 μg/mL Incubation Duration: 24 hrs (hours) Experimental Results: No significant accumulation of LDH in the cell culture medium |
| Animal Protocol |
Animal/Disease Models: lung tumor mice [3] Doses: 10 μg/mouse Route of Administration: intraperitoneal (ip) injection Experimental Results: The growth of lung metastases in tumor-bearing mice was Dramatically diminished. . The number of lung lesions was diminished to approximately 40%. The number of BAL fluid cells increased Dramatically. Increased levels of INF-γ and IL-17A and diminished levels of IL-13. Increased TLR3 expression. Animal/Disease Models: Middle cerebral artery occlusion (MCAO) model mouse [5] Doses: 1.25 mg/kg Route of Administration: intraperitoneal (ip) injection Experimental Results: Reduce focal brain I/R injury. Increase the expression of Bcl2, Hsp27 and Hsp70, reduce Bax expression, and reduce cell degeneration and apoptosis. Downregulating TLR4 signaling through TLR3 prevents cerebral ischemia and provides protection against cerebral I/R injury. |
