cAMP-Dependent Cytosolic Mislocalization of p27kip-Cyclin D1 During Quinol-Thioether-Induced Tuberous Sclerosis Renal Cell Carcinoma
The loss of tuberin, the tuberous sclerosis-2 (Tsc-2) gene product, is associated with cytoplasmic mislocalization of p27 in uterine leiomyomas derived from Eker rats (Tsc-2EK/+) and in human metastatic renal cell carcinoma tissue. Signaling associated with cytoplasmic mislocalization of p27 in renal cancer is relatively unknown. Renal tumors derived from 2,3,5-tris-(glutathion-S-yl)hydroquinone (TGHQ)-treated Tsc-2EK/+ rats, and null for tuberin, display elevated nuclear and cytosolic p27, with parallel increases in cytosolic cyclin D1 levels. Similar changes are observed in TGHQ-transformed renal epithelial cells derived from Tsc-2EK/+ rats (QTRRE cells), which, in addition to the cytoplasmic mislocalization of p27 and cyclin D1, exhibit high ERK, B-Raf, and Raf-1 kinase activity.

Health benefits of POM juice overstated, judge rules
POM Wonderful, perhaps the best-known purveyor of pomegranate juice, has failed to prove that its tangy thirst-quencher can prevent or reduce the risk of heart disease, prostate cancer and erectile dysfunction, a U.S. judge says. (Source: CTV Health)
