Tumor-initiating stem cells (SCs) exhibit distinct patterns of transcription factors and gene expression compared to healthy counterparts. Here, we show that dramatic shifts in large open-chromatin domain (super-enhancer) landscapes underlie these differences and reflect tumor microenvironment. By in vivo super-enhancer and transcriptional profiling, we uncover a dynamic cancer-specific epigene...

This study was conducted using butyric acid as a growth enhancer in the diets of Clarias gariepinus and Oreochromis niloticus. C. gariepinus (42.39 g ±1.17) were fed diets containing varying inclusion levels of butyric acid (BA); 0 (CG1), 0.5 (CG2), 1.0 (CG3), 1.5 (CG4), 2.0 (CG5) g kg -1, where, CG1 is the control or reference diet. O. niloticus (25.50 g ± 0.50) were also fed diets containing ...

OBJECTIVE Short stature caused by point mutations or deletions of the short stature homeobox (SHOX) gene (SHOX haploinsufficiency (SHI)) is a registered indication for GH treatment. Patients with a SHOX enhancer deletion (SED) have a similar phenotype, but their response to GH is unknown. It is uncertain if duplications of SHOX or its enhancer (SDUP) cause short stature. This study aimed to des...

Surveillance of left ventricular function, part current US Food and Drug Administration recommendations for anti-human epidermal growth factor receptor 2 (anti-HER2) chemotherapy, is based on historical data involving patients who received concomitant anthracycline therapy, a key enhancer cardiac risk. More recent anti-HER2 treatment suggest that cardiotoxicity detected by screening rare usuall...

The application of exogenously applied salicylic acid plays important roles in improving the growth, yield, and bioactive compound compositions different plant species. Curcuma longa is a medicinal that commonly used as spice food additive, has antioxidant potential. In this study, an innovative strategy for enhancing active production was investigated by applying natural growth enhancer—namely...

Gene expression variation is a major contributor to phenotypic diversity within species and is thought to play an important role in adaptation. However, examples of adaptive regulatory polymorphism are rare, especially those that have been characterized at both the molecular genetic level and the organismal level. In this study, we perform a functional analysis of the Drosophila melanogaster CG...

The cyclin-dependent kinase (CDK)-inhibitor 1C (CDKN1C) gene is expressed from the maternal allele and is located within the centromeric imprinted domain at chromosome 11p15. It is a negative regulator of proliferation, with loss-of-function mutations associated with the overgrowth disorder Beckwith-Wiedemann syndrome. Recently, gain-of-function mutations within the PCNA domain have been descri...

The loss of gap junctional intercellular communication is characteristic of neoplastic cells, suggesting that the restoration with a gap junction enhancer may be a new therapeutic treatment option with less detrimental effects than traditional antineoplastic drugs. A gap junction enhancer, 6-methoxy-8-[(2-furanylmethyl) amino]-4-methyl-5-(3-trifluoromethylphenyloxy) quinoline (PQ7), on the norm...

We have recently shown that a thyroid hormone-responsive transcription stimulatory element exists in the 5'-flanking DNA near the rat growth hormone (rGH) gene (Crew, M. D., and Spindler, S. R. (1986) J. Biol. Chem. 261, 5018-5022). Progressive deletion-transfection analysis of the 5' end of the gene has led to the identification of two genetic elements responsive to thyroid hormone. The first ...

The present study was conducted to evaluate the efficacy of wood betony (WB), Stachys lavandulifolia extract on growth performance and some immune responses in common carp, Cyprinus carpio. Different concentrations of the WB extract 0, 2, 4 and 8% (g per 100 g of diet) were added to commercial diet. Each treatment was randomly assigned to triplicate groups of fish having average initial weight ...
