Comparison of tamoxifen and letrozole response in mammary preneoplasia of ER and aromatase overexpressing mice defines an immune-associated gene signature linked to tamoxifen resistance.
Carcinogenesis 36(1) , 122-32, (2015) Response to breast cancer chemoprevention can depend upon host genetic makeup and initiating events leading up to preneoplasia. Increased expression of aromatase and estrogen receptor (ER) is found in... |

Hypogonadism Associated with Cyp19a1 (Aromatase) Posttranscriptional Upregulation in Celf1 Knockout Mice.
Mol. Cell. Biol. 35 , 3244-53, (2015) CELF1 is a multifunctional RNA-binding protein that controls several aspects of RNA fate. The targeted disruption of the Celf1 gene in mice causes male infertility due to impaired spermiogenesis, the ... |

Aromatase (Cyp19a1b) in the pituitary is dynamically involved in the upregulation of lhb but not fshb in the vitellogenic female ricefield eel Monopterus albus.
Endocrinology 155(11) , 4531-41, (2014) Aromatase, encoded by Cyp19a1, is expressed in the pituitary of vertebrates; however, its physiological relevance remains poorly defined. In teleosts, the duplicated cyp19a1b is preferentially express... |
