Receptor tyrosine kinase-like orphan receptor (ROR) proteins are a conserved family of tyrosine kinase receptors that function in developmental processes including cell survival, differentiation, cell migration, cell communication, cell polarity, proliferation, metabolism, and angiogenesis. ROR1 has recently been shown to be expressed in various types of cancer cells but not normal cells. Pharmacokinetics and pharmacodynamics of single-chain Fragment variable (scFv) antibodies provide potential therapeutic advantages over whole antibody molecules...

BACKGROUND: Post-marketing reports suggest that finasteride causes sexual dysfunction despite a low incidence reported in clinical trials. Therefore, the extent of risk remains unknown. OBJECTIVE: To determine whether the risk of sexual dysfunction is higher among individuals treated with finasteride compared to a baseline risk for all other drugs using the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) database. METHODS: A case by non-case disproportionality approach was used whereby a Reporting Odds Ratio (ROR) with 95% confidence interval (CI) was calculated...

In recent years, there has been an increasing interest in understanding the contributory factors to run-off-road (ROR) crashes in the US, especially those where large trucks are involved. Although there have been several efforts to understand large-truck crashes, the relationship between crash factors, crash severity, and ROR crashes is not clearly understood. The intent of this research is to develop statistical models that provide additional insight into the effects that various contributory factors related to the person (driver), vehicle, crash, roadway, and environment have on ROR injury severity...

Tumor necrosis factor-α (TNF-α) inhibitors are increasingly being used as treatment for rheumatoid arthritis (RA). However, the administration of these drugs carries the risk of inducing injection site reaction (ISR). ISR gives rise to patient stress, nervousness, and a decrease in quality of life (QoL). In order to alleviate pain and other symptoms, early countermeasures must be taken against this adverse event. In order to improve understanding of the risk factors contributing to the induction of ISR, we evaluated the association between TNF-α inhibitors and ISR by applying a logistic regression model to age-stratified data obtained from the Food and Drug Administration Adverse Event Reporting System (FAERS) database...

Mental disorders are neuropsychiatric conditions that are marked by unusual or irregular thinking, feelings, or behavior, and lead to distress and/or impaired functions. Major psychiatric conditions are depression, anxiety, and psychoses of various types. Their etiopathogeneses, of a primary or secondary origin, are associated with genetic and environmental factors. They are commonly treated with psychoactive drugs (also known as psychotropics), which target serotonin, dopamine, norepinephrine, glutamate, and nuclear receptors (NRs), including retinoic acid receptor-related orphan receptors (RORs) and other receptors in the central nervous system (CNS)...

Targeting the transcriptional activity of nuclear hormone receptors has proven an effective strategy to treat certain human diseases, and they have become a major focus point to develop novel therapies for the treatment of cancer, inflammation, autoimmune diseases, metabolic disorders, and others. One family of nuclear receptors that has attracted most interest in recent years is the retinoic acid receptor-related orphan receptors (RORs), in particular RORγ. RORγ is a critical regulator of the immune system and RORγ antagonists have shown activity in animal models of inflammatory autoimmune diseases...

ROR-alpha is a nuclear receptor, activity of which can be modulated by natural or synthetic ligands. Due to its possible involvement in, and potential therapeutic target for atherosclerosis, we aimed to identify ROR-alpha target genes in monocytic and endothelial cell lines. We performed chromatin immunoprecipitation (ChIP) followed by tiling array (ChIP-on-chip) for ROR-alpha in monocytic cell line THP1 and endothelial cell line HUVEC. Following bioinformatic analysis of the array data, we tested four candidate genes in terms of dependence of their expression level on ligand-mediated ROR-alpha activity, and two of them in terms of promoter occupancy by ROR-alpha...

Directed cell migration is critical for metazoan development. During Caenorhabditis elegans development many neuronal, muscle and other cell types migrate. Multiple classes of proteins have been implicated in cell migration including secreted guidance cues, receptors for guidance cues and intracellular proteins that respond to cues to polarize cells and produce the forces that move them. In addition, cell surface and secreted proteases have been identified that may clear the migratory route and process guidance cues...

ROR-family receptor tyrosine kinases form a small subfamily of receptor tyrosine kinases (RTKs), characterized by a conserved, unique domain architecture. ROR RTKs are evolutionary conserved throughout the animal kingdom and act as alternative receptors and coreceptors of WNT ligands. The intracellular signaling cascades activated downstream of ROR receptors are diverse, including but not limited to ROR-Frizzled-mediated activation of planar cell polarity signaling, RTK-like signaling, and antagonistic regulation of WNT/β-Catenin signaling...

BACKGROUND: Interleukin (IL)-17 produced by mainly T helper 17 (Th17) cells may play an important destructive role in chronic periodontitis (CP). Thus, anti-inflammatory cytokines, such as IL-35, might have a beneficial effect in periodontitis by inhibiting differentiation of Th17 cells. Th17 differentiation is regulated by the retinoic acid receptor-related orphan receptor (ROR) α (encoded by RORA) and RORγt (encoded by RORC). However, the role of IL-35 in periodontitis is not clear and the effect of IL-35 on the function of Th17 cells is still incompletely understood...

This study investigates factors that significantly contribute to the severity of driver injuries resulting from single-vehicle run-off-road (SV ROR) crashes. A mixed logit model approach is employed to explore the potential unobserved heterogeneous effects associated with each age group: young (ages 16-24), middle-aged (ages 25-65), and older drivers (ages over 65). Likelihood ratio tests indicated that the development of separate injury severity models for each age group is statistically superior to estimating a single model using all data...

CD4(+) NKG2D(+) T cells are associated with tumour, infection and autoimmune diseases. Some CD4(+) NKG2D(+) T cells secrete IFN-γ and TNF-α to promote inflammation, but others produce TGF-β and FasL to facilitate tumour evasion. Here, murine CD4(+) NKG2D(+) T cells were further classified into NK1.1(-) CD4(+) NKG2D(+) and NK1.1(+) CD4(+) NKG2D(+) subpopulations. The frequency of NK1.1(-) CD4(+) NKG2D(+) cells decreased in inflamed colons, whereas more NK1.1(+) CD4(+) NKG2D(+) cells infiltrated into colons of mice with DSS-induced colitis...

Type Ⅱ innate lymphoid cells (ILC2) is a family of innate immune lymphocytes, which provide effective immune responses to cytokines. ILC2 are regulated by the nuclear transcription factor ROR alpha and GATA3, secreting cytokines IL-5 and IL-13, etc. Animal models have shown that ILC2 are involved in allergic diseases, such as asthma and atopic dermatitis, and also play a very important role in the metabolic balance. In addition, recent reports suggest that ILC2 not only play a role in the initial stages of the disease, but also can lead to chronic pathological changes in the disease, such as fibrosis, and may have an effect on acquired immunity...

Ultraviolet B (UVB), in addition to having carcinogenic activity, is required for the production of vitamin D3 (D3) in the skin which supplies >90% of the body's requirement. Vitamin D is activated through hydroxylation by 25-hydroxylases (CYP2R1 or CYP27A1) and 1α-hydroxylase (CYP27B1) to produce 1,25(OH)2D3, or through the action of CYP11A1 to produce mono-di- and trihydroxy-D3 products that can be further modified by CYP27B1, CYP27A1, and CYP24A1. The active forms of D3, in addition to regulating calcium metabolism, exert pleiotropic activities, which include anticarcinogenic and anti-melanoma effects in experimental models, with photoprotection against UVB-induced damage...
