REVIEW The term Wnt derives from a contraction of the gene name Wingless, first identified in the development of the fruit fly Drosophila, and the proto-oncogene Int-1 (Integration 1), which was first isolated in mammary tumor in the mouse 1 (for a review, see ref. 2). Wnt/β-catenin signaling pathway controls a myriad of biological phenomena throughout(More)
The aim of the present study was to investigate the role of each estrogen receptors on the regulation of proteins involved with proliferation and differentiation of Sertoli cells from 15-day-old rats. Activation of ESR1 by 17β-estradiol (E2) and ESR1-selective agonist PPT increased CCND1 expression, and this effect was dependent on NF-kB activation. E2 and(More)
The aim of the present study was to characterize the mechanism underlying estrogen effects on the androgen-independent prostate cancer cell line PC-3. 17β-estradiol and the ERβ-selective agonist DPN, but not the ERα-selective agonist PPT, increased the incorporation of [methyl-(3)H]thymidine and the expression of Cyclin D2, suggesting that ERβ mediates the(More)
The aim of the present study was to investigate the activation of rapid signaling events by 17β-estradiol in the rat uterus. 17β-Estradiol induced a rapid increase of total [3H]-inositol phosphate accumulation in the whole uterus and endometrium, but not in the myometrium. The effect of 17β-estradiol in the endometrium was blocked by phospholipase C (PLC)(More)
The aim of this study was to identify the expression, cellular localization and regulation of classic estrogen receptors ERα and ERβ, ER-α36 isoform and GPER in the androgen-independent prostate cancer cell line PC-3. In addition, we evaluated the relative contribution of these receptors to the activation of the ERK1/2 (extracellular signal-regulated(More)
The aim of the present study was to investigate the involvement of estrogen receptors in the activation of phospholipase C (PLC)-phosphoinositide hydrolysis in the hippocampus from rats in estrous and proestrous phases. 17β-Estradiol (E2) and ESR1-selective agonist PPT, but not ESR2-selective agonist DPN, induced a rapid increase on total [³H]-inositol(More)
