01/01/2005 - "In this study, we evaluated the TEF approach in experimental 2-year rodent cancer bioassays with female Harlan Sprague-Dawley rats receiving 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 3,3 ,4,4 ,5-pentachlorobiphenyl (PCB-126), 2,3,4,7,8-pentachlorodibenzofuran (PeCDF), or a mixture of the three compounds. "
05/01/1991 - "Previous studies showed that 2,3,4,7,8-pentachlorodibenzofuran (PenCDF) and 1,2,3,4,7,8-hexachlorodibenzofuran (HCDF) could produce tumors in the liver and subcutaneous tissues of rats by subcutaneous administration. "
05/01/2006 - "The recent National Toxicology Program (NTP) cancer bioassays for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 2,3,4,7,8-pentachlorodibenzofuran (4-PeCDF) permit a reevaluation of the current TEF value of 4-PeCDF. "

05/01/1989 - "Maximal inhibition of increase in body weight and decrease in daily locomotor activity were observed in the rats treated with 370 micrograms/kg of these compounds at 3 to 4 weeks after treatment, especially with 2,3,4,7,8-pentachlorodibenzofuran. "
08/01/1988 - "To characterize the toxicity of 2,3,4,7,8-pentachlorodibenzofuran (4PeCDF), male F344 rats were administered a single oral dose of 0, 100, 250, 500, 1000, or 2000 micrograms 4PeCDF/kg. A progressive and dose-dependent loss of body weight was evident by 3 days after treatment. "
07/01/1997 - "B6C3F1 female mice were treated via oral gavage a total of five times, with 3 weeks between each dosing, with 0, 1, 3, or 10 micrograms 2,3,7,8,-TCDD/kg body weight (bw); 3 or 30 mg 2,2',4,4',5,5'-hexachlorobiphenyl (PCB 153)/kg bw; 100, 300, or 1000 micrograms 3,3',4,4',5-pentachlorobiphenyl (PCB 126)/kg bw; 10, 30, or 100 micrograms 2,3,4,7,8-pentachlorodibenzofuran (4-PeCDF)/kg bw; or 2 or 20 mg 1,3,6,8-TCDD/kg at 10 ml/kg bw. "

08/01/2013 - "Ingestion of 2,3,4,7,8-pentachlorodibenzofuran (2,3,4,7,8-PeCDF) was considered to be the cause of this poisoning. "
10/02/2008 - "Association of clinical findings in Yusho patients with serum concentrations of polychlorinated biphenyls, polychlorinated quarterphenyls and 2,3,4,7,8-pentachlorodibenzofuran more than 30 years after the poisoning event."

03/01/2008 - "TCDD, 1,2,3,7,8-pentachlorodibenzo-p-dioxin (PeCDD), 2,3,7,8-tetrachlorodibenzofuran (TCDF), 2,3,4,7,8-pentachlorodibenzofuran (PeCDF), and 3,3',4,4',5-pentachlorobiphenyl (PCB126) induced CYP1A1-dependent activities in HEK293 human embryonic kidney, Panc1 pancreatic cancer, and Hepa1c1c7 mouse hepatoma cell lines.
