REVIEW
Yan Man, Gang Liang, An Li, Ligang Pan
Mycotoxins are one of the main factors impacting food safety. Mycotoxin contamination has threatened the health of humans and animals. Conventional methods for the detection of mycotoxins are gas chromatography (GC) or liquid chromatography (LC) coupled with mass spectrometry (MS), or enzyme-linked immunosorbent assay (ELISA). However, all these methods are time-consuming, require large-scale instruments and skilled technicians, and consume large amounts of hazardous regents and solvents. Interestingly, a microchip requires less sample consumption and short analysis time, and can realize the integration, miniaturization, and high-throughput detection of the samples...

Mio Shibuta, Mitsutomo Abe
In facultative long-day plant, Arabidopsis thaliana, FLOWERING LOCUS T (FT) encoding a mobile hormone florigen plays an essential role in modulating the optimal timing of flowering to ensure reproductive success. Under inductive long-day conditions, the transcription of FT is activated by the CONSTANS (CO)/NUCLEAR FACTOR-Y (NF-Y) protein complex in leaf phloem companion cells. FT is transported to the shoot apical meristem through interaction with florigen transporters, such as SODIUM POTASSIUM ROOT DEFECTIVE 1 (NaKR1)...

Background: The transcriptional regulation of the human AT1R gene in pathophysiologies, like the metabolic syndrome, is poorly understood. The human AT1R gene has polymorphisms in its promoter that can be arranged in two haplotypes. Variants -810T, -713T, -214A, and -153A always occur together (Hap-I) and variants -810A, -713G, -214C, and -153G form Hap-II. We have hypothesized that high fat diet will alter cellular transcriptional milieu and increase hAT1R gene expression in a haplotype-dependent manner...

Background: CUX1, which encodes an auxiliary factor in base excision repair, resides on 7q22.1, the most frequently and highly amplified chromosomal region in glioblastomas. The resistance of glioblastoma cells to the mono-alkylating agent temozolomide is determined to some extent by the activity of the apurinic/apyrimidinic endonuclease 1, APE1. Methods: To monitor the effect of CUX1 and its CUT domains on APE1 activity, DNA repair assays were performed with purified proteins and cell extracts...

Since there are several predicting factors associated with the comet assay parameters, we have decided to assess the impact of seasonal variations on the comet assay results. A total of 162 volunteers were retrospectively studied, based on the date when blood donations were made. The groups (winter, spring, summer and autumn) were matched in terms of age, gender, smoking status, body mass index and medical diagnostic exposure in order to minimise the impact of other possible predictors. Means and medians of the comet assay parameters were higher when blood was sampled in the warmer period of the year, the values of parameters being the highest during summer...

As PD-1/PD-L1 immune checkpoint inhibitors exhibited promising clinical outcomes in various types of solid tumors, PD-1/PD-L1 blockades have been explored for the treatment of hepatocellular carcinoma (HCC). However, the association of PD-L1 with antitumor immunoregulation is not clearly defined in HCC. Here, we evaluated the characteristics of PD-L1 expression, CD8 T-cell infiltration and their relationship in HCC. A total of 411 resected tumor specimens from HCC patients were immunostained for PD-L1 and CD8...

BACKGROUND/AIMS: Quercetin, a flavonoid found in onions and other vegetables, has potential inhibitory effects on bone resorption in vivo and in vitro. In our previous study, we found that quercetin treatment reversed lipopolysaccharide (LPS)-induced inhibition of osteoblast differentiation through the mitogen-activated protein kinase (MAPK) pathway in MC3T3-E1 cells. In this study, we investigated the underlying mechanisms of pretreatment with quercetin on apoptosis and the inhibition of osteoblast differentiation in MC3T3-E1 cells induced by LPS...

MP0250 is a multi-domain drug candidate currently being tested in clinical trials for the treatment of cancer. It comprises one anti-vascular endothelial growth factor-A (VEGF-A), one anti-hepatocyte growth factor (HGF), and two anti-human serum albumin (HSA) DARPin® domains within a single polypeptide chain. While there is first clinical validation of a single-domain DARPin® drug candidate, little is known about DARPin® drug candidates comprising multiple domains. Here, we show that MP0250 can be expressed at 15 g/L in soluble form in E...

E-cadherin and β-catenin are key proteins that are essential in the formation of the epithelial cell layer in the colon but their regulatory pathways that are disrupted in cancer metastasis are not completely understood. Mutated in colorectal cancer (MCC) is a tumour suppressor gene that is silenced by promoter methylation in colorectal cancer and particularly in patients with increased lymph node metastasis. Here, we show that MCC methylation is found in 45% of colon and 24% of rectal cancers and is associated with proximal colon, poorly differentiated, circumferential and mucinous tumours as well as increasing T stage and larger tumour size...

Phosphatidylinositol-3 kinase pathway regulates multiple cellular function involving cell survival, growth, motility proliferation, apoptosis, and adhesion. These are deregulated in various diseases like cancer, atherosclerosis, and inflammation. PI3Ks phosphorylate phosphatidylinositol 4,5 biphosphate (PIP2) yielding phosphatidylinositol 3, 4, 5 triphosphate (PIP3) that in turn activates AKT kinase (serine/threonine kinase) which is the central enzyme in regulation of metabolic functions. Due to their implications in disease pathophysiology, PI3K/AKT inhibitors became attractive targets for pharmaceutical industries...

The non-structural (NS1) protein is a multifunctional molecular protein encoded by influenza A virus genome. NS1 plays an important role in inhibition of host immune responses. In order to assess the cellular localization of NS1 in different influenza A virus subtypes, we performed the immunofluorescence assay to observe the cellular location of NS1 after infection with influenza A virus WSN (H1N1), PR8 (H1N1), CA04 (H1N1), SD (H9N2) and AH01 (H7N9) in A549 cells and MDCK cells respectively. According to the results, NS1-WSN and NS1-PR8 accumulated mainly in cytoplasm at 24 h post infection, while the NS1-CA04 and NS1-SD appeared major in the nucleus...

Oncolytic viruses are an emerging class of cancer therapeutics that couple cytotoxicity with the induction of an anti-tumor immune response. Host-virus interactions are complex and modulated by a tumor microenvironment whose immunosuppressive activities can limit the effectiveness of cancer immunotherapies. In an effort to improve this aspect of oncolytic virotherapy, we combined the oncolytic herpes virus HSV1716 with the transforming growth factor beta receptor 1 (TGF-βR1) inhibitor A8301 to treat syngeneic models of murine rhabdomyosarcoma...
