Objective To investigate the effect of artesunate (ART) on neuroinflammation in depressed mice by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon gene (STING) pathway. Methods Mice were divided into model group, control group, low-dose ART group, high-dose ART group, fluoxetine group, and high-dose ART+RocA (CGAS-STING pathway activator) group. Sugar solution consumption experiment and forced swimming experiment were applied to evaluate the depressive behavior of mice; HE staining microscopy was applied to detect pathological changes in hippocampal tissue; ELISA method was applied to detect the level of interleukin-6(IL-6), tumor necrosis factor-a(TNF-α), serotonin (5-HT) and dopamine (DA); TUNEL staining microscopy was applied to detect neuronal apoptosis; Western blot was applied to detect Bcl-2 associated X protein (Bax), p53, cGAS, and STING proteins. Results Compared to the control group, the mice in the model group exhibited neuronal pustule degeneration, the sugar water consumption rate, level of 5-HT and DA decreased, the rest time of forced swimming increased. The level of IL-6 and TNF-a, neuronal apoptosis rate, expression of Bax, p53, GAS, and STING proteins all elevated (P<0.05); Compared with model group, the damage to hippocampus neurons in the ART low-dose group, ART high-dose group and fluoxetine group neuronal pustular degeneration was alleviated, while sugar water consumption rate, 5-HT, and DA levels increased, the rest time of forced swimming reduced, the level of IL-6 and TNF-a, neuronal apoptosis rate and the expression of Bax, p53, CGAS, and STING proteins reduced (P<0.05); RocA reversed the improvement effect of high-dose ART on depression in mice. Conclusions ART inhibits neuroinflammation and neuronal apoptosis in depressed mice, and up-regulates amine neurotransmitters expression. The mechanism is potentially related to the blocking of CGAS-STING pathway. [ABSTRACT FROM AUTHOR]

, Henan 450046;2. The Shennong Laboratory, Zhengzhou, Henan 450046) Abstract [Objective] This study aims to analyze the population structure and conservation priorities of local chicken breeds in China to promote sustainable and healthy development of animal husbandry. [Method] The study collected whole-genome re-sequencing data of 96 individuals from eight breeds. The population structure was analyzed by principal component analysis (PCA), constructing a phylogenetic tree, and analyzing inbreeding and genetic distances. The increase or decrease in overall gene and allele diversity was calculated by removing each breed, and the contribution of each breed to the synthesis of a population with maximum gene and allele diversity was simulated to systematically evaluate breed conservation priorities. [Result] The results showed that the eight breeds were divided into four clusters, with the highest differentiation between the Tibetan chicken and other breeds, which was further divided into two subclusters. The other breeds were divided into two clusters, northern and southern. The contribution of Tibetan chicken to genetic diversity is the highest; followed by Wenchang chicken and Yao chicken, these three should be considered as the priority conservation breeds. [Conclusion] The results of this study will provide a reference for the protection, development and utilization of local chicken breeds. [ABSTRACT FROM AUTHOR]

Objective To identify the key microRNAs (miRNAs) and their target genes associated with the prognosis of triple-negative breast cancer (TNBC) and to discuss their roles in regulatory biological functions and signaling pathways, and to provide the theoretical basis for the selection of prognostic biomarkers for the patients with TNBC. Methods The differentially expressed miRNAs between the TNBC patients and non-TNBC patients were selected based on The Cancer Genome Atlas (TCGA) Database； survival analysis was used to clarify the miRNAs related to the prognosis of the patients；miRDB and miRWalk3.0 online Databases were used to screen for the miRNA target gene； Cytoscape 3.8.2 software was used to elucidate the miRNA-messenger RNA (mRNA) regulatory network；the limma package in R software was used to screen the differentially expressed miRNAs of the TNBC patients and non-TNBC patients； the clusterProfiler package in R software was used to analyze the biological functions and pathways involved by the target genes. Results The survival analysis results showed that miR-9, miR-17, miR-31, miR-146a, miR-188, and miR-190b were associated with the prognosis of the TNBC patients, and low expression levels of these miRNAs were correlated with the poorer prognosis of the patients. A total of 224 target genes regulated by these six miRNAs were identified. The Gene Ontology (GO) functional enrichment analysis results showed that the target genes were primarily involved in the development of mammary alveoli, positive regulation of DNA transcription, and angiogenesis.The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis results showed that the target genes were mainly enriched in cytokine-cytokine receptor interaction and insulin secretion signaling pathways. The network analysis results identified the key genes in the regulatory network, including solute carrier family 24 member 2 (SLC24A2), vav guanine nucleotide exchange factor 3 (VAV3), tripartite motif containing 36 (TRIM36), synaptotagmin 1 (SYT1), pleckstrin and Sec7 domain containing 3 (PSD3), peroxisome proliferator-activated receptor α (PPARA), RNA polymerase Ⅲ subunit G (POLR3G), pleomorphic adenoma gene 1 (PLAG1), ubiquitin associated and SH3 domain containing B (UBASH3B), and SH3 domain and tetramerization domain containing 2 (SH3TC2)； the interactions of miRNA-mRNA of miR-9-SYT1, miR-9-KIF13B, miR-9-KITLG, miR-17-SLC24A2, miR-31-SLC24A2, miR-146a-SYT1, miR-146a-KIF13B, miR-188-SLC24A2, and miR-188-SLC24A2 were the closest. Conclusion MiR-9, miR-17, miR-31, miR-146a, miR-188, miR-190b and their target genes are involved in physiological processes such as mammary alveolar development and angiogenesis, which are closely associated with the poor prognosis of the patients with TNBC.
