ABSTRACT
The anti-inflammatory activity of non-selective estrogens has been attributed to their ability to antagonize the activity of nuclear factor kappaB (NF-kappaB), a known mediator of inflammatory responses. Here we report the identification of a potent new class of pathway-selective ER ligands that selectively antagonize NF-kappaB functional activity, while exhibiting a lack of classical estrogenic effect.

Mucolipidosis type IV (MLIV) is a neurodegenerative lysosomal storage disorder that occurs in an increased frequency in the Ashkenazi Jewish (AJ) population. The frequency of the disease in this population has been established by the testing of 66,749 AJ subjects in the Dor Yeshorim program, a unique premarital population-screening program designed for the Orthodox Jewish community. A carrier rate of 0.0104 (95% C.I 0.0097-0.011) was found. The distribution of the 2 AJ founder mutations, namely, c.416-2A>G and c.1_788del, was determined to be 78.15% and 21.85%, respectively. Three novel mutations were identified in non-Jewish MLIV patients, a missense mutation c.1207C>T, p.Arg403Cys; a 2bp deletion, c.302_303delTC; and a nonsense, c.235C>T, Gln79X.
