Atrazine (ATZ) is a triazine herbicide that is widely used in agriculture and has been detected in surface and underground water. Recently, laboratory and epidemiological research have found that the bioaccumulation of ATZ in the environment leads to biotoxicity in the human immune and endocrine systems and results in tumor development.

To investigate the effects of ATZ exposure on epithelial ovarian cancer (EOC) cells and elucidate the potential mechanisms governing these effects.

The human EOC cell lines Skov3 and A2780 were used in this study to explore the effects and mechanisms of ATZ exposure on EOC. The mouse embryonic osteoblastic precursor MC3T3-E1 cells served as the control cells to determine the effects of ATZ on cancer cell lines. After exposure to ATZ, the MTT assay, flow cytometry, the colony formation assay, immunohistochemical staining, the cell scratch assay, and the Transwell assay were used to evaluate the proliferative activity, invasion, and migration capabilities of EOC cell linesment did not affect the level of p53/p21 mRNA compared to the control groups. Moreover, there was no significant change in the expression levels of Stat3 and p-Stat3 in MC3T3-E1 cells exposed to ATZ. This phenomenon was observed while the proliferation rate was enhanced in MC3T3-E1 cells by ATZ.

The results of this study suggest that ATZ effectively promotes the proliferation and metastasis of EOC cells through the Stat3 signaling pathway by inducing low levels of ROS. Additionally, although ATZ might also induce proliferative potential in normal cells, the mechanisms governing its effects in these cells might be different from those in EOC cells.

Cranberry (
Ait.) has high developmental prospects and great research value. Cranberry has a narrow genetic base, however, its morphological characteristics are not easily distinguishable. Besides, traditional breeding methods are limited, and breeding progress on cranberry cultivars has been slow.

The objective of this study was to assess polymorphic EST-SSR markers developed from a cranberry fruit transcriptomic sequencing library to provide candidate EST-SSR sequences for future research on stress resistance breeding of cranberry.

Thirteen cranberry accessions were used for EST-SSR analysis, and 16 accessions of other
specieswere used to test primer transferability. Genomic DNA was extracted from young leaves of 6-year-old cranberry plants and subjected to PCRamplification. A binary matrix was established and analyzed in NTSYS-pc v.2.10e for calculation of the genetic similarity of cranberry cultivars and construction of a cluster dendrogram.

A total of47 stress-resistance-related primer pairs were designed, of which 7 pairs showed polymorphism. The average number of effective alleles was 1.844, and the average expected heterozygosity was 0.455. The average transfer rate was 63.39%. Genetic similarity coefficients ranged from 0.28 to 1.00, with an average of 0.76. UPGMA clustering divided the 13 cranberry accessions into four groups at a genetic similarity of 0.74.

The seven polymorphic EST-SSR markers were able to reveal genetic relationships among 13 cranberry accessions and can be used for future research on stress resistance breeding of cranberry.

However, the role of iNOS expression in osteosarcoma (OS) is far from being fully understood. find more In present work, iNOS levels were detected in OS tissues and cell lines. Colony formation assay, Transwell assay, and fow cytometer were used to assess proliferation, migration, invasion, and apoptosis abilities in vitro after iNOS inhibition. Western blotting determined the expressions of iNOS, MMP2, MMP9, C-MYC, Ki67, PCNA, and β-catenin. Mice transfected with OS cells were to evaluate tumor formation. IHC assay was to evaluate the expressions of iNOS and β-catenin in mice. The results showed that iNOS was upregulated in both OS tissues and cells compared with that in matched normal tissues or cells. And we found that proliferation, migration, and invasion numbers of OS cells were decreased, and apoptosis numbers of OS cells were increased after iNOS inhibition. MMP2, MMP9, C-MYC, Ki67, and PCNA levels were also reduced in OS cells treated with iNOS inhibition. Else, iNOS inhibition would suppress β-catenin expression in OS cells to regulate MMP2, MMP9, C-MYC, Ki67, and PCNA expressions. In addition, tumor formation, iNOS expression, and β-catenin expression were inhibited in mice transplanted with iNOS knockout OS cells. These results indicated that iNOS might be a potential therapeutic target for OS.Systemic juvenile idiopathic arthritis (sJIA) is a severe autoinflammatory disorder with a still not clearly defined molecular mechanism. To better understand the disease, we used scattered datasets from public domains and performed a weighted gene coexpression network analysis (WGCNA) to identify key modules and hub genes underlying sJIA pathogenesis. Two gene expression datasets, GSE7753 and GSE13501, were used to construct the WGCNA. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were applied to the genes and hub genes in the sJIA modules. Cytoscape was used to screen and visualize the hub genes. We further compared the hub genes with the genome-wide association study (GWAS) genes and used a consensus WGCNA to verify that our conclusions were conservative and reproducible across multiple independent datasets. A total of 5,414 genes were obtained for WGCNA, from which highly correlated genes were divided into 17 modules. The red module demonstrated the highest correlation with the sJIA module (r = 0.8, p = 3e -29), whereas the green-yellow module was found to be closely related to the non-sJIA module (r = 0.62, p = 1e -14). Functional enrichment analysis demonstrated that the red module was mostly enriched in the activation of immune responses, infection, nucleosomes, and erythrocytes, and the green-yellow module was mostly enriched in immune responses and inflammation. Additionally, the hub genes in the red module were highly enriched in erythrocyte differentiation, including ALAS2, AHSP, TRIM10, TRIM58, and KLF1. The hub genes from the green-yellow module were mainly associated with immune responses, as exemplified by the genes KLRB1, KLRF1, CD160, and KIRs. We identified sJIA-related modules and several hub genes that might be associated with the development of sJIA. Particularly, the modules may help understand the mechanisms of sJIA, and the hub genes may become biomarkers and therapeutic targets of sJIA in the future.Health-related quality of life (HRQoL) is one of the most important indicators in assessing the health and well-being of HIV-positive patients. The present study investigated the HRQoL of HIV patients referred to Abadan's Voluntary Counseling and Testing (VCT) center in 2019. In this cross-sectional study, a total of 134 HIV+ patients referred to Abadan's VCT center were selected through convenience sampling. Demographic information was collected through a researcher-made checklist; the patients' status and health information were collected through electronic medical records of HIV+ patients and their records at the VCT center. The HRQoL index was assessed using the World Health Organization (WHOQOL-BREF) questionnaire. Data analysis was carried out using simple and multiple linear regression as well as a t-test in SPSS software. A P value  less then  0.05 was considered as the significance level in all tests. The mean of the HRQoL in all the participating patients was 56.42 ± 22.66. The highest and lowest mean scores of HRQoL domains were related to social relationships (57.53 ± 24.73) and environmental health (53.68 ± 19.07). There was a positive significant relationship between the marital status, residency, years of education, duration of infection, transmission route, and antiretroviral (ARV) therapy with the score of the HRQoL. The results showed a moderate score for the mean HRQoL and its domains. The present study revealed the necessity of improving HIV+ patients' living conditions, employment status, health education, and mental health care.Acacia catechu (L.f.) Willd is a profoundly used traditional medicinal plant in Asia. Previous studies conducted in this plant are more confined to extract level. Even though bioassay-based studies indicated the true therapeutic potential of this plant, compound annotation was not performed extensively. This research is aimed at assessing the bioactivity of different solvent extracts of the plant followed by annotation of its phytoconstituents. Liquid chromatography equipped with high resolution mass spectrometry (LC-HRMS) is deployed for the identification of secondary metabolites in various crude extracts. On activity level, its ethanolic extract showed the highest inhibition towards α-amylase and α-glucosidase with an IC50 of 67.8 ± 1 μg/mL and 10.3 ± 0.1 μg/mL respectively, inspected through the substrate-based method. On the other hand, the plant extract showed an antioxidant activity of 23.76 ± 1.57 μg/mL, measured through radical scavenging activity. Similarly, ethyl acetate and aqueous extracts of A. catechu showed significant inhibition against Staphylococcus aureus with a zone of inhibition (ZoI) of 13 and 14 mm, respectively. With the LC-HRMS-based dereplication strategy, we have identified 28 secondary metabolites belonging to flavonoid and phenolic categories. Identification of these metabolites from A. catechu and its biological implication also support the community-based usage of this plant and its medicinal value.The microarray cancer data obtained by DNA microarray technology play an important role for cancer prevention, diagnosis, and treatment. However, predicting the different types of tumors is a challenging task since the sample size in microarray data is often small but the dimensionality is very high. Gene selection, which is an effective means, is aimed at mitigating the curse of dimensionality problem and can boost the classification accuracy of microarray data. However, many of previous gene selection methods focus on model design, but neglect the correlation between different genes. In this paper, we introduce a novel unsupervised gene selection method by taking the gene correlation into consideration, named gene correlation guided gene selection (G3CS). Specifically, we calculate the covariance of different gene dimension pairs and embed it into our unsupervised gene selection model to regularize the gene selection coefficient matrix. In such a manner, redundant genes can be effectively excluded. In addition, we utilize a matrix factorization term to exploit the cluster structure of original microarray data to assist the learning process.
