The orphan nuclear receptor steroidogenic factor 1 (SF-1) initially wasisolated as a key regulator of the cytochrome P450 steroid hydroxylases.Knockout mice lacking steroidogenic factor 1 (SF-1) have a complexendocrine phenotype that encompasses adrenal and gonadal agenesis,impaired expression of gonadotropins by pituitary gonadotropes, andstructural abnormalities of the ventromedial hypothalamic nucleus (VMH).These multiple defects complicate efforts t...

Keith Parker, University of Texas Southwestern Medical Center, Dallas, TX, USA AbstractThe son of two clinician-scientists, Keith Parker attended Williams College, and then received his M.D./Ph.D. degrees from Washington University School of Medicine in 1981. His graduate work with Donald Shreffler focused on structure-function relationships of the complement component, C4....

The need for new therapeutic options in diabetes has become increasingly apparent. Until recently transplantation of isolated islets has had limited success. The Edmonton Protocol has described how many of the problems can be overcome, but has highlighted the need to develop methods of expanding islets cells in culture to provide sufficient tissue to meet the potentially huge demand for this treatment. We have focused on three approaches: 1. deriving replicating human Beta cel...

Intrauterine infection, a common antecedent of premature birth, leads to increased levels of interleukin-1 (IL-1) in the amniotic fluid. IL-1 in amniotic fluid and cord blood is a risk factor for the postnatal development of chronic lung disease. On the other hand, intrauterine inflammation may protect the preterm newborn from respiratory distress syndrome. A single intra-amniotic injection of IL-1 given to fetal animals increases surfactant protein synthesis and surfactant po...

Introduction: Premature newborns are defined as babies born before 37 weeks of pregnancy and after 22 weeks of pregnancy as a viability limit. This study aimed to analyse growth characteristics at the age of second and third age and the prevention of metabolic diseases that may occur in adult age at an early phase.Methods: This study was conducted as a retrospective cohort study between May 2021 and October 2021 in 18 different Outpatient Clinics in Patn...

Cardioprotective actions of urocortin (Ucn) I have been proposed by several studies and may play a critical role on stress adaptation. And one of the beneficial actions on cardiovascular cells may be anti-oxidative actions. In addition, Ucn I may be regulated by oxidative stress, therefore, the present study is designed to reveal anti-oxidative actions of Ucns on cardiomyocytes. Mouse atrial cell line, HL-1 cardiomyocytes, was cultured in standard Claycomb medium supplemented ...

Prostate cancer have been most cause of cancer death to men in recent, but there are not effective treatments for this cancer. In growth of prostate cancer, steroid hormones such as androgen play a role in their growth and survival. However, endocrine disrupting chemicals (EDCs) intend to bind the hormone receptor and induce the abnormal hormone response. EDCs have potency to activate estrogen receptor (ER) and androgen receptor (AR) mediated signaling pathways, and they cause...

Resveratrol (trans-3,4,5-trihydroxystilbene, RES), a phytoestrogen, exists in grape skin and red wine. Endocrine disrupting chemicals (EDCs) appear to promote the development and progression of the estrogen dependant cancers. In this study, we evaluated the inhibitory effect of RES on the cell growth and progression induced by various EDCs in BG-1 ovarian cancer cells expressing estrogen receptors (ERs). The various EDCs, i.e., bisphenol A (BPA), nonylphenol (NP), octylphenol ...

One of estrogens, 17b-estradiol (E2), is a pleiotropic hormone that regulates the growth and differentiation of many tissues and also acts as a mitogen that promotes the development and proliferation of hormone-responsive cancers. Bisphenol A (BPA) is a widely used industrial compound and classified as one of endocrine disrupting chemicals (EDCs) and especially a xenoestrogen that imitates estrogen in living organisms. In this study, we examined the effect of a phytoestrogen, ...
