Purpose: To assess the association betweenpreoperative serum total testosterone (tT), 17b-estradiol (E2), sex hormone–binding globulin (SHBG), and tT–E2 ratio values with high-risk prostate cancer (as defined by the National Comprehensive Cancer Network practice guidelines) at radical prostatectomy. Experimental Design: Serum E2, tT, and SHBG were dosed the day before surgery (7:00–11:00 am) in...

CURRENTLY, ABOUT 66% OF ADULTS are overweight, and approximately 33% of adults are clinically obese. Excess weight is a risk factor for numerous conditions, including cardiovascular disease, diabetes, dyslipidemia, hypertension, stroke, cancer, adverse reproductive outcomes, osteoarthritis, and premature death (2, 10). Obesity is associated with a systemic state of inflammation and leads to inc...

Bovine viral diarrhoea virus (BVDV) isolates infect cultured Madin-Darby bovine kidney (MDBK) cells as efficiently as sheep kidney cells. In contrast, border disease virus (BDV) propagates poorly in MDBK cells but infects sheep cells very efficiently. The envelope glycoprotein E2 has been shown to be essential for virus infectivity. To explore the potential role of E2 in pestivirus host range i...

indirect evidence suggests that estrogen is involved in the etiology of breast cancer. estrogen is also thought to modulate nitric oxide (no) in human breast tumor tissue via regulation of inducible nitric oxide synthase (inos). objectives of this study were to determine whether estradiol (e2) affects inos expression level in breast cancer cells and to study the effect of various concentrations...

introduction: the development of an effective vaccine against hepatitis c virus (hcv) is still a target of intensive vaccine research. the hcv envelope proteins e1 and e2 which can induce broadly neutralizing antibodies are the major candidate for this purpose. different types of expression systems have been used to express these glycoproteins. in this study, an expression system using pichia p...

A sex steroid-binding protein (SBP) that binds to 17 b-estradiol with high affinity and moderate capacity was identified in the plasma of female and juvenile of kutum (Rutilus frisii kutum) sampled during the early stage of gonadal maturation in October and prior to spawning in March. Mean maximum specific binding (Bmax) and equilibrium dissociation constant (Kd) of the fish were as follows: In...

Administration of 17β-estradiol (E2) has beneficial effects on cognitive function in peri- but not post-menopausal women, yet the molecular mechanisms underlying age-related changes in E2 action remain unclear. We propose that there is a biological switch in E2 action that occurs coincident with age and length of time after ovarian hormone depletion, and we hypothesized that age-dependent regul...

Besides its crucial role in many physiological events, 17β-estradiol (E2) exerts protective effects in the central nervous system. The E2 effects are not restricted to the brain areas related with the control of reproductive function, but rather are widespread throughout the developing and the adult brain. E2 actions are mediated through estrogen receptors (i.e., ERα and ERβ) belonging to the n...
