Rose-comb was one of the chicken comb-variants first used by Bateson and Punnet in 1902 to demonstrate Mendelian inheritance in animals. Rose-comb is a monogenic trait that has been widely described in chickens. It is caused by a large structural rearrangement that leads to mis-expression of transcription factor MNR2 on chromosome 7. Rose-comb has pleiotropic effects in homozygous roosters, which is associated with poor sperm mobility. It was postulated that this is caused by the disruption of the CCDC108 gene located at the distal inversion breakpoint...

BACKGROUND: Hypothyroidism is associated with obesity, and thyroid hormones are involved in the regulation of body composition, including fat mass. Genome-wide association studies (GWAS) in adults have identified 19 and 6 loci associated with plasma concentrations of thyroid stimulating hormone (TSH) and free thyroxine (fT4), respectively. OBJECTIVE: This study aimed to identify and characterize genetic variants associated with circulating TSH and fT4 in Danish children and adolescents and to examine whether these variants associate with obesity...

Nicotinamide phosphoribosyltransferase (NAMPT) is an adipokine-enzyme, which was described as to play bioactivities both in the intracellular and in the extracellular environment. However, while the functions of intracellular NAMPT (iNAMPT) are well known, much less is known on extracellular NAMPT (eNAMPT), also called visfatin or pre-B cell colony-enhancing factor. iNAMPT catalyzes the rate-limiting step in the NAD+ biosynthesis pathway from nicotinamide. Its inhibition severely reduces intracellular NAD+ levels, achieving anti-inflammatory and anti-cancer effects...

Nicotinamide phosphoribosyltransferase (NAMPT) is a pleiotropic protein implicated in the pathogenesis of acute respiratory distress syndrome, aging, cancer, coronary heart diseases, diabetes, nonalcoholic fatty liver disease, obesity, rheumatoid arthritis, and sepsis. However, the underlying molecular mechanisms of NAMPT in these physiological and pathological processes are not fully understood. Here, we provide experimental evidence that a Nampt gene homozygous knockout (Nampt(-/-)) resulted in lethality at an early stage of mouse embryonic development and death within 5-10 days in adult mice accompanied by a 25...

To determine whether the integrative variants, haplotypes and diplotypes of the calpain 3 (CAPN3) and the FERM domain containing 5 genes (FRMD5) and several environmental exposures are associated with an implication in lipid homeostasis, which are associated with cardiovascular risk. Genotyping of the CAPN3 rs4344713 and FRMD5 rs524908 was performed by Sanger sequencing in 1,640 subjects (Jing, 819 and Han, 821). Multivariate analyses of covariance models that adjusted by age, gender, body mass index (BMI), blood pressure and lifestyle (smoking and drinking), were constructed using variants, haplotypes and diplotypes of the CAPN3 rs4344713 and FRMD5 rs524908 as predictors and changes in lipid variables...

Interleukin-1β (IL-1β) is a pleiotropic cytokine and a crucial mediator of inflammatory and immune responses. IL-1β processing and release are tightly controlled by complex pathways such as NF-kB/ERK1/2, to produce pro-IL-1β, and NALP3/ASC/Caspase-1 inflammasome, to produce the active secreted protein. Dysregulation of both IL-1β and its related pathways is involved in inflammatory/autoimmune disorders and in a wide range of other diseases. Identifying molecules modulating their expression is a crucial need to develop new therapeutic agents...

Resistant starch (RS) is beneficial to human health. In order to reduce the current prevalence of diabetes and obesity, several transgenic and mutant crops containing high RS content are being developed. RS content of steamed rice with starch-branching enzyme (BE)IIb-deficient mutant endosperms is considerably high. To understand the mechanisms of RS synthesis and to increase RS content, we developed novel mutant rice lines by introducing the gene encoding starch synthase (SS)IIa and/or granule-bound starch synthase (GBSS)I from an indica rice cultivar into a japonica rice-based BEIIb-deficient mutant line, be2b...

Neurofibromatosis type 1 is a genetic disorder characterized by variable phenotypic manifestations. The diagnostic criteria, 25 established in 1987, are broad to encompass these pleiotropic findings. Included are the specific osseous manifestations of 26 sphenoid dysplasia and dysplasia or thinning of the cortex of long bones. This review highlights recent evidence on the role of 27 neurofibromin in bone development and suggests consideration for additional diagnostic criteria.

Hydroxychloroquine, due to its multifaceted pleiotropic benefits including anti-inflammatory effects has great potential in reducing cardiovascular (CV) morbidity and mortality. CV outcome data of hydroxychloroquine is available through 2 retrospective studies in rheumatoid arthritis patients, both of which have not considered congestive heart failure (CHF) as an outcome measure. CHF is an important CV outcome and is more common than myocardial infarction and stroke; and increased age is associated with increased risk of CHF...

High-fat diets (HFD) impair hippocampal-dependent learning and memory and produce important changes in synaptic transmission by enhancing glutamate uptake, decreasing synaptic efficacy, and inhibiting plasticity mechanisms such as N-methyl-D-aspartate-mediated long-term depression (LTD) within the hippocampus. Adolescent animals seem to be particularly susceptible to the detrimental effect of HFD as dietary treatments carried out between weaning and early adulthood are much more efficient in terms of hippocampal damage that those carried out during the adult period...

Various survival factors such as the pleiotropic cytokine interleukin-6 (IL-6), a major mediator of inflammation and activator of signal transducer and activator of transcription 3 (STAT3), serve to block apoptosis in cancer cells. Our present study revealed that the expression of IL-6, while not other IL-2, IL-4, IL-8, or IL-10, was significantly elevated in resistance of renal carcinoma cells (RCC) when compared with human renal proximal tubule epithelial cell line HK-2. The inhibition of IL-6 by siRNA can suppress the proliferation, migration and invasion of RCC cells and increase the doxorubicin (Dox) sensitivity...

Different life stages frequently respond to the same environmental cue to regulate development so that each life stage is matched to its appropriate season. We investigated how independently each life stage can respond to shared environmental cues, focusing on vernalization, in Arabidopsis thaliana plants. We first tested whether effects of rosette vernalization persisted to influence seed germination. To test whether genes in the vernalization flowering pathway also influence germination, we assessed germination of functional and nonfunctional alleles of these genes and measured their level of expression at different life stages in response to rosette vernalization...

REVIEW
Pascal Kessler, Pascale Marchot, Marcela Silva, Denis Servent
Three-finger fold toxins are miniproteins frequently found in Elapidae snake venoms. This fold is characterized by three distinct loops rich in β-strands and emerging from a dense, globular core reticulated by four highly conserved disulfide bridges. The number and diversity of receptors, channels, and enzymes identified as targets of three-finger fold toxins is increasing continuously. Such manifold diversity highlights the specific adaptability of this fold for generating pleiotropic functions. Although this toxin superfamily disturbs many biological functions by interacting with a large diversity of molecular targets, the most significant target is the cholinergic system...

The Jak-STAT pathway is one of many pleiotropic signaling pathways that plays an important role in organismal development and in response to changing environmental cues. As a key signaling cascade for cytokines and growth factors, Jak-STAT plays central role in the innate and adaptive immune system. Cytokines control the stability, commitment, and maturation of cytotoxic and helper T cells, parts of the adaptive immune system that mediate immunity to pathogens and are linked to inflammatory diseases. Dysregulation of Jak-STAT protein expression or function leads to autoimmunity, allergic diseases, and cancer...

A major pleiotropic quantitative trait locus (QTL) located at ~25 Mbp on bovine chromosome 14 affects a myriad of growth and developmental traits in Bos taurus and indicus breeds. These QTL have been attributed to two functional variants in the bidirectional promoter of PLAG1 and CHCHD7. Although PLAG1 is a good candidate for mediating these effects, its role remains uncertain given that these variants are also associated with expression of five additional genes at the broader locus. In the current study, we conducted expression QTL (eQTL) mapping of this region using a large, high depth mammary RNAseq dataset representing 375 lactating cows...

Pancreatic cancer management remains a major challenge to society. Poor prognosis results in dismal survival rates and quality of life for pancreatic cancer patients post chemo/radiation therapies. Although progress has been made in drug development for chemotherapeutics targeting pancreatic cancer, accompanying issues of resistance to these drugs renders the treatment futile. Emerging area of cancer chemoprevention is gaining importance with natural/dietary compounds serving as novel agents with strong anticancer properties; these are pleiotropic agents targeting multiple pathways with minimal toxicities in the surrounding normal tissue...

This research is the first to demonstrate that OsSAUR45 is involved in plant growth though affecting auxin synthesis and transport by repressing OsYUCCA and OsPIN gene expression in rice. Small auxin-up RNAs (SAURs) comprise a large multigene family and are rapidly activated as part of the primary auxin response in plants. However, little is known about the role of SAURs in plant growth and development, especially in monocots. Here, we report the biological function of OsSAUR45 in the model plant rice (Oryza sativa)...
