Apoptosis is considered to be a way of eliminating unwanted cells without causing major inflammation. Nevertheless, several lines of evidence show that apoptotic cell-derived antigens can be strong immunogens. The rabies virus glycoprotein G-ERA is an apoptotic molecule. We tested the ability of G-ERA to potentiate a B cell response against an exogenous antigen (influenza hemagglutinin, HA). We...

BACKGROUND This study analyzes factors associated with differences in long-term outcomes after hepatic resection for metastatic colorectal cancer over time. STUDY DESIGN Sixteen-hundred consecutive patients undergoing hepatic resection for metastatic colorectal cancer between 1985 and 2004 were analyzed retrospectively. Patients were grouped into 2 eras according to changes in availability of...

Phytoestrogens exert pleiotropic effects on cellular signaling and show some beneficial effects on estrogen-dependent diseases. However, due to activation/inhibition of the estrogen receptors ERa or ERb, these compounds may induce or inhibit estrogen action and, therefore, have the potential to disrupt estrogen signaling. We performed a comprehensive analysis and potency comparison of phytoestr...

Environmental estrogen mimics, including metalloestrogens that can activate estrogen receptor-alpha (ERa), may contribute to breast cancer risk. However, the underlying mechanisms through which these molecular mimics activate the ERa are generally poorly understood. With concern to this important question, we investigated whether intracellular calcium may mediate the cross-talk between signalin...

We have shown that PBHs can be formed in the matter-dominated era if gravity is described by Brans-Dicke theory. Considering an early matterdominated era in between inflation and reheating, we found that the PBHs which are formed during this era lives longer than the standard case where PBHs are formed in early radiation-dominated era. Thus in comparison with stanard scenario more number of PBH...

Era is an essential gene in E. coli, encoding a GTP-binding protein of unknown function. In the present work, a mutant designated Era-dE, for deletion of effector region is described. This is the first and only known era allele that confers a dominant-negative phenotype. Phenotypic analysis of the mutant showed that overproduction of Era-dE caused a dominant inhibition of growth when TCA cycle ...

PURPOSE Tamoxifen is an antiestrogen used in women who have estrogen receptor (ER)-alpha-positive breast cancer. Unfortunately, resistance to tamoxifen is common in women with metastatic disease and side effects, including increased risk of endometrial cancer, exist. Here we describe the activity of a new selective ER modulator, ERA-923, in preclinical models focused on these limitations. EXP...

OBJECTIVE To compare time to clinical worsening (TTCW) based on initial oral therapy for pulmonary arterial hypertension (PAH) in patients with systemic sclerosis (SSc)-related PAH. METHODS Using data from the Pulmonary Hypertension Assessment and Recognition of Outcomes in Scleroderma (PHAROS) registry (a multicenter prospective observational study enrolling SSc patients with incident pulmon...

Escherichia coli Era is a GTP binding protein and essential for cell growth. We have previously reported that an Era mutant, designated Era-dE, causes a dominant negative effect on the growth and the loss of the ability to utilize TCA cycle metabolites as carbon source when overproduced. To investigate the role of Era, the gene expression in the cells overproducing Era-dE was examined by DNA mi...
