Metastasis is a complex process requiring directed migration of metastatic cells to favorable microenvironments. Increased CXCR4 expression has been implicated in more invasive, aggressive and metastatic tumor phenotypes and poor patient survival...
Dehydroepiandrosterone (DHEA) is a C-19 adrenal steroid and the most abundant circulating hormone in humans. Since circulating levels decline in late adulthood, treatment of humans with DHEA has been suggested to have beneficial health effects....
Interactions between chemokines and their receptors are involved in organ- specific homing and propagation of metastatic breast cancer (BrCa) cells. BrCa cells express higher levels of CXCR4 and CXCR7 mRNA and cell surface protein, than normal...
Introduction: Hyperhomocysteinemia (HHcy) is a pathological condition characterized by excessive levels of plasma homocysteine (Hcy). Patients with HHcy are reported to be at risk for arrhythmias like atrial fibrillation and sudden cardiac death...
Polymorphisms in the adrenergic receptor beta-2 (ADRB2) gene have been studied in relation to risk of Type 2 diabetes and obesity, but few studies have investigated associations with breast cancer. The purpose of this research was to evaluate the...
The fundamental question of the exact nature of the role played by TNF in the failing myocardium remains one of contention. Many preclinical studies have demonstrated beneficial effects with TNF antagonism and recently the dichotomous role played...
Xenoestrogens are spread throughout the environment affecting our daily
lives and may produce potential toxic effects on human health. The purpose of
this study was to develop a mechanistically reliable model capable of identifying
xenoestrogens....
In the retina, the receptive fields (RFs) of most neurons are comprised of an excitatory center and a suppressive surround. Retinal ganglion cell (RGC) RF center excitatory input arises from bipolar cell (BC) inputs, while their surround arises...
While investigating estrogen response element (ERE) binding properties of Erα in de-identified human breast cancer extracts, additional proteins were observed that recognized ERE sequences (ERE-BP). In order to unravel the apparent role of these...
Complement, an early recognition system of innate immunity that senses local tissue damage and infection, cross-talks with and regulates other signaling systems, including Toll-like receptor (TLR) pathways. In the context of periodontitis,...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Embryonic development requires the orchestration of temporally precise genetic events that culminate in the formation of a complete organism. The molecular mechanisms responsible for ontogenesis are regulated by environmental and somatic factors in...
It has been shown that GSK3 β plays a critical role in the inflammation response by differentially regulating MyD88-dependent pro- and anti-inflammatory cytokines production in TLR4-stimulated innate immune cells. The work included in this...
Periodontitis--Age factors; Natural immunity; Age factors in disease
Age-related alterations in innate immunity are poorly understood. The identification of those mechanisms, which are dysfunctional in old age, will shed light on potential therapeutic strategies for chronic inflammatory diseases prevalent in the...
The vaccinia virus complement control protein (VCP) is involved in the modulation of the host inflammatory response during vaccinia virus infection. It possesses the ability to inhibit both classical and alternative pathways of complement...
Congenital stationary night blindness 1 (CSNBl) is a genetic disorder characterized in humans by night blindness, low visual acuity and myopia. CSNB 1 is caused by defects in genes that are involved in signaling between photoreceptors and...
Inflammatory bowel disease (IBD) is a chronic autoimmune disorder that is subdivided into Crohn's disease (CD), ulcerative colitis (UC), and indeterminate colitis (IC). Epidemiological studies have proven that genetic variation increases...
Females have a higher incidence of autoimmune diseases than males for reasons that are currently unknown. CD4+CD25+ regulatory T cells play an important role in the maintenance of immunological homeostasis and self-tolerance by suppressing...
Mishaps in prenatal development can influence mammary gland development
and, ultimately, affect susceptibility to factors that cause breast cancer. This research was
based on the underlying hypothesis that maternal dietary composition during...
Inflammation is now recognized as an important factor in several age-related diseases such as arthritis, atherosclerosis, multiple sclerosis and diabetes. In each case, sub-clinical chronic inflammation occurs over years and leads to progressive...
