03/01/2002 - "3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a disinfection by-product in chlorinated drinking water, induces follicular tumors in thyroid glands in Wistar rats. "
01/01/2000 - "No consistent pattern of mutations in p53 and ras genes in liver tumors of rat treated with the drinking water mutagen 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX)."
06/18/1997 - "3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a byproduct of the chemical reactions that occur in chlorinated drinking water, has been found to be mutagenic in bacteria and mammalian cells; however, its potential to cause tumors in animals has not been tested previously. "
06/18/1997 - "Water chlorination, 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), and potential cancer risk."
01/01/2000 - "The frequency of point mutations in p53 (exons 4-7) and in Ki-ras, Ha-ras, and N-ras (exons 1 and 2) and the expression of p53 protein were evaluated in the liver tumors of Wistar rats of a 104-week carcinogenicity study on 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a chlorine disinfection by-product in drinking water. "

02/28/2004 - "3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), the potent bacterial mutagen produced during chlorination of drinking water, was tested for the induction of oxidative stress in two murine cell lines: NIH 3T3 (fibroblasts) and L929 (fibrosarcoma cells). "
03/01/2007 - "The aim of this study was to investigate the induction of reactive oxygen species in murine L929 fibrosarcoma cells exposed to radiofrequency (RF) radiation at 900 MHz, with or without co-exposure to 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a potent environmental carcinogen produced during chlorination of drinking water. "

10/10/2004 - "This study determines the effects of a water disinfection by-product, 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as mutagen X or MX) and chlorinated tap water on genomic instability in the yeast Saccharomyces cerevisiae. "

05/01/1999 - "The modifying effects of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a mutagenic by-product in chlorinated water, on the development of glandular stomach cancers were investigated in Wistar rats. "
