Osteosarcoma is one of the most malignant cancer adolescents and young adults and metastatic osteosarcoma is a huge life threat with a 5-year survival lower than 20%. However, the mechanisms through which localized osteosarcoma turned metastatic are not fully understood. Here, we studied the role of miR-204-5p in osteosarcoma and found that miR-204-5p is downregulated in both osteosarcoma patients and osteosarcoma cell lines. Read More

Scope: In this review, we attempt to assess how choline and folate transporters affect fetal development. We focus on how the expression of these transporters in response to choline and folate intake affects transport effectiveness. We additionally describe allelic variants of the genes encoding these transporters and their phenotypic effects. Read More

Antimicrobial peptides are one of the promising substitutes for conventional antibiotics. To examine their potential usefulness for controlling bacterial infections, the present study aimed to determine the induction of the self-destruction of Escherichia coli mediated by bac8c, which was modified from template peptide bactenecin. The potential of bac8c (RIWVIWRR) was reflected by the change in physiological following exposure, which led to the accumulation of reactive oxygen species (ROS) with an imbalance in the antioxidant system and damage to the intracellular lipids.

Apoptotic endonucleases act cooperatively to fragment DNA and ensure the irreversibility of apoptosis. However, very little is known regarding the potential regulatory links between endonucleases. Deoxyribonuclease 1 (DNase I) inactivation is caused by alternative splicing (AS) of DNase I pre-mRNA skipping exon 4, which occurs in response to EndoG overexpression in cells. Read More

Serotonin (5-hydroxytriptamine; 5-HT) is a fascinating neurotransmitter that thanks to an extensive axonal network is released throughout the entire central nervous system (CNS) and exerts its action on the modulation of a countless number of physiological, behavioral and cognitive processes. In addition, cumulating evidences have linked alteration in 5-HT neurotransmission with the onset of psychiatric and neurodevelopmental disorders, such as depression, autisms and schizophrenia. Nevertheless only 5% of the total body content of serotonin exerts its action in the CNS, while the rest is synthetized and stored in peripheral tissues where it acts as an autacoid. Read More

Background: Fatty acids (FAs), and especially monounsaturated FAs (MUFAs) stimulate GLP-1 release. However, lipotoxicity is indicated in GLP-1 secreting cells following long-term exposure to elevated levels of saturated FAs (SFAs) in vivo and in vitro, where in vitro studies indicate that cosupplementation with MUFAs confers lipoprotection. SFAs and MUFAs differentially affect the fate of cells in ways that depend on the cell type, concentration and ratio of the FAs. Read More

Binding of indoloquinolines with different aliphatic side chains to a parallel G-quadruplex derived from the MYC promoter sequence was characterized by optical and calorimetric measurements. ITC experiments performed at different temperatures enabled the determination of molar heat capacity changes upon quadruplex binding and a partitioning of the total binding free enthalpy into contributing terms with hydrophobic effects being major driving forces for all derivatives. Whereas affinities increase for indoloquinolines equipped with a long and positively charged side arm, the highest contribution of specific intermolecular interactions anticipated to impart enhanced specificity is found for a ligand with an uncharged ether aliphatic tail.

PA1 (dIm-PyPyβPyPyPy-γ-PyPyβPyPyPyPyβ-Ta) is a large (14-ring) hairpin polyamide that was designed to recognize the DNA sequence 5'-WGW-3', where W is either A or T. As is common among the smaller 6-8-ring hairpin polyamides (PAs), it binds its target recognition sequence with low nM affinity. However, in addition to its large size, it is distinct from these more extensively characterized PAs in its high tolerance for mismatches and antiviral properties. Read More

Lipid membranes have an essential role in most physiological processes including cell protection, cell-to-cell communication and regulation of intracellular signaling. These multiple roles of biological membranes prompted the study and the development of artificial lipid membranes with the primary aim to reconstitute the natural functions in vitro and understand the interaction between all membrane components at the molecular level. Tethered bilayer lipid membranes (tBLMs) are emerging as the ideal experimental platform for functional and structural studies on membrane-associated proteins due to their peculiar properties such as their stability and fluidity of both leaflets in the phospholipid bilayer.

Short upstream open reading frames (uORFs) are the most prevalent cis-acting regulatory elements in the mammalian transcriptome which can orchestrate mRNA translation. Apart from being "passive roadblocks" that decrease expression of the main coding regions, particular uORFs can serve as specific sensors for changing conditions, thus regulating translation in response to cell stress. Here we report a novel uORF-based regulatory mechanism that is employed under conditions of hyperosmotic stress by at least two human mRNAs, coding for translation reinitiation/recycling factor eIF2D and E3 ubiquitin ligase MDM2.

The expression of serotonin (5-HT) in the retina was first reported in the sixties. The detection of vesicular monoamine transporter and serotonin receptors in several retinal cells confirm that 5-HT is playing a neuromodulatory role in this structure. Whereas signaling pathways activated by 5-HT receptor binding has been poorly investigated so far, numerous data demonstrated that 5-HT is involved in retinal physiology, retinal physiopathology and photoreceptor survival.

The five-year survival rate of esophageal cancer patients is less than 20%. This may be due to increased resistance (acquired or intrinsic) of tumor cells to chemo/radiotherapies, often caused by aberrant cell cycle, deregulated apoptosis, increases in growth factor signaling pathways, and/or changes in the proteome network. In addition, deregulation in non-coding RNA-mediated signaling pathways may contribute to resistance to therapies. Read More

Extracellular Hsp70 (eHsp70) can activate immune cells via Toll-like receptors (TLR) 2 and 4, and induce cytokine synthesis. The aim of this study was to explore inflammation-associated effects of eHsp70 alone and in combination with cigarette smoke extract (CSE) in primary bronchial epithelial cells. We assessed IL-6 and IL-8 concentrations, TLR2, TLR4 and Hsp70 mRNA expressions, and mitogen-activated protein kinases (MAPKs) activation induced by recombinant human (rh) Hsp70, CSE or their combinations in normal human bronchial epithelial cells (NHBE) obtained commercially, and primary bronchial epithelial cells isolated from non-COPD lung donors (PBEC) or COPD patients (PBEC COPD).

Although 24(S)-hydroxycholesterol (24S-OHC) plays an important role to maintain homeostasis of cholesterol in the brain, it induces neuronal cell death at high concentrations. 24S-OHC-induced cell death was suppressed by γ-tocopherol (γ-Toc) but not by γ-tocotrienol (γ-Toc3) in a similar way to α-tocopherol (α-Toc) and α-tocotrienol (α-Toc3) in human neuroblastoma SH-SY5Y cells. Both γ-Toc and γ-Toc3 significantly inhibited cumene hydroperoxide-induced cell death, as previously shown in the case of α-Toc and α-Toc3. Read More

Bacterial 5' untranslated regions of mRNA, termed thermal switches or thermometers, change their structure in response to temperature change. This structural change provides for the regulation of gene expression. One of such thermal switches, called fourU, is present in the Salmonella species. Read More
