Seleno-short-chain chitosan (SSCC) is a synthesized chitosan derivative. In this study, antitumor activity and underlying mechanism of SSCC on human non-small-cell lung cancer A549 cells were investigated in vitro. The MTT assay showed that SSCC could inhibit cell viability in a dose- and time-dependent manner, and 200 μg/ml SSCC exhibited significantly toxic effects on A549 cells. The cell cycle assay showed that SSCC triggered S phase cell cycle arrest in a dose- and time-dependent manner, which was related to a downregulation of S phase associated cyclin A...

5-Fluorouracil (5-FU) as a chemotherapeutic drug is used to treat colorectal cancer (CRC). However, 5-FU is associated with acquired CRC resistance, which decreases the therapeutic potential of 5-FU. Several studies indicated that miR-200c is also involved in chemotherapeutic drug resistance, but the exact mechanism of miR-200c mediated chemoresistance has not yet been fully understood. In this study, we examined the effect of inhibition of miR-200c on the sensitivity of HCT-116 cells to 5-FU. HCT-116 cells were transfected with LNA-anti- miR-200c for 48 h...

Sertoli cells are essential for regulating normal spermatogenesis. However, the mechanisms underlying human Sertoli cell development remain largely elusive. Here we examined the function and signaling pathways of BMP6 in regulating human Sertoli cells. RT-PCR, immunocytochemistry and Western blots revealed that BMP6 and its multiple receptors were expressed in human Sertoli cells. CCK-8 and EDU assays showed that BMP6 promoted the proliferation of Sertoli cells. Conversely, BMP6 siRNAs inhibited the division of these cells...

Electrochromism with the ring-closing or ring-opening isomerization of substituted and unsubstituted bis(3-thienyl)/(2-thienyl)hexafluorocyclopentene is discussed using the DFT method. In the neutral ground state, bond making and breaking between two reactive C atoms on thienyls are thermodynamically forbidden. Under redox conditions, the gain or loss of electrons can have a significant effect on the frontier molecular orbital distribution of both open- and closed-ring isomers, particularly in reactive sites...

Pi class of glutathione S-transferase (GST) is known to suppress c-Jun N-terminal kinase (JNK)-related apoptosis through protein-protein interactions. Moreover, signaling by PKA/cAMP response element binding protein (CREB) is necessary for GSTP up-regulation. This study explored whether carnosic acid (CA) from rosemary prevents 6-hydroxydopamine (6-OHDA)-induced neurotoxicity by inhibition of JNK through GSTP via PKA/CREB signaling. Results indicated that the GSTP protein was increased in SH-SY5Y cells treated with CA for 18 and 24 h...

Organic materials containing arylamines have been widely used as hole-transporting materials as well as emitters in organic light-emitting devices (OLEDs). However, it has been pointed out that the C-N bonds in these arylamines can easily suffer from degradation in excited states, especially in deep-blue OLEDs. In this work, phenanthro[9,10-d]imidazole (PI) is proposed as a potential donor with higher stability than those of arylamines. Using PI as the donor, a donor-acceptor type deep-blue fluorophore 1-phenyl-2-(4″-(1-phenyl-1H-benzo[d]imidazol-2-yl)-[1,1':4',1″-terphenyl]-4-yl)-1H-phenanthro[9,10-d]imidazole (BITPI) is designed and synthesized...

Foot-and-mouth disease (FMD) is a devastating animal disease. Strategies for differentiation of infected from vaccinated animals (DIVA) remain very important for controlling disease. Development of an epitope-deleted marker vaccine and accompanying diagnostic method will improve the efficiency of DIVA. Here, a monoclonal antibody (Mab) was found to recognize a conserved "AEKNPLE" epitope spanning amino acids 109-115 of non-structural protein (NSP) 3A of foot-and-mouth disease virus (FMDV; O/Tibet/CHA/99 strain), which could be deleted by a reverse-genetic procedure...

Type 2 diabetes (T2D) is a progressive disease characterized by sustained hyperglycemia and is frequently accompanied by hyperlipidemia. Deterioration of β-cell function in T2D patients may be caused, in part, by long-term exposure to high concentrations of glucose and/or lipids. We developed systems to study how chronic glucotoxicity and lipotoxicity might be linked to the impairment of glucose-stimulated insulin secretion (GSIS) machinery in pancreatic β-cells. INS-1 (832/13) were exposed to glucose and/or palmitate for up to 10 weeks...

S-RNase-based self-incompatibility is found in Solanaceae, Rosaceae, and Scrophulariaceae, and is the most widespread mechanism that prevents self-fertilization in plants. Although 'Shatian' pummelo (Citrus grandis), a traditional cultivated variety, possesses the self-incompatible trait, the role of S-RNases in the self-incompatibility of 'Shatian' pummelo is poorly understood. To identify genes associated with self-incompatibility in citrus, we identified 16 genes encoding homologs of ribonucleases in the genomes of sweet orange (Citrus sinensis) and clementine mandarin (Citrus clementine)...
