Bactrian camels serve as an important means of transportation in the cold desert regions China and Mongolia. Here we present a 2.01 Gb draft genome sequence from both wild domestic bactrian camel. We estimate camel to be 2.38 Gb, containing 20,821 protein-coding genes. Our phylogenomics analysis reveals that shared common ancestors with other even-toed ungulates about 55–60 million years ago. Rapidly evolving genes lineage are significantly enriched metabolic pathways, these changes may...

Since it was first described in 1968, immunoglobulin (Ig)A nephropathy (IgAN) has become the most commonly diagnosed form of primary glomerular disease worldwide. A number reports have shown that toll‑like receptor 9 (TLR9) and B‑cell activating factor (BAFF) may be associated with IgAN; however, sufficient evidence not yet to delivered. In present study, serum levels BAFF as well TLR9 mRNA protein peripheral blood mononuclear cells (PBMCs) were assessed. Expression PBMCs examined by...

Objective: Janus kinase (JAK)-signal transducer and activator of transcription (STAT) signaling pathway is closely related to tumorigenesis. Suppressors cytokine 3 (SOCS3) a negative regulator JAK-STAT pathway. MiR-340 expression significantly upregulated in gastric cancer (GC) tissue. This study investigated the role miR-340 regulating SOCS3 affecting GC cell proliferation, cycle, apoptosis.Patients methods: Dual luciferase assay was used verify targeted relationship between SOCS3. tissue...

Cardiac dysfunction in diabetic cardiomyopathy may be associated with abnormal Ca2+ homeostasis. This study investigated the effects of alterations homeostasis and sarcoplasmic reticulum Ca2+-associated proteins on cardiac function development cardiomyopathy. Sprague–Dawley rats were divided into 4 groups (n = 12, each): a control group, streptozotocin-induced rat models diabetes groups, examined after 4, 8, or 12 weeks. Evaluations structure performed by echocardiography hemodynamic...

Hepatocellular carcinoma (HCC) is the sixth most lethal neoplasm worldwide. Traditional biomarkers often exploit relationship between a certain gene and cancer progression, but they cannot predict patient survival or prognosis accurately. We aim to construct new DNA repair-related signature that combines several genes improve prediction in HCC.We selected an HCC mRNA sequencing (mRNA-seq) dataset (n=365) from The Cancer Genome Atlas (TCGA), set enrichment analysis (GSEA) was used explore...

Dobutamine, a sympathomimetic agent, is widely used clinically, influencing cardiac output, heart rate (HR), and blood pressure (BP), which may impact cerebral flow (CBF), critical for brain metabolism. However, the effects of dobutamine on CBF internal carotid artery (ICA) remain unclear, with contradictory reported in both clinical animal studies. It necessary to investigate cervical hemodynamics. This study aimed evaluate infusion ICA CBF, explore their relationship, identify factors...

BACKGROUND Ezrin-radixin-moesin (ERM) plays an important role in multiple links of tumors. It also involved breast cancer invasion and metastasis, might be a potential biomarker cancer. Another study suggested that ERM expression was regulated directly by miR-200c, had critical miR-200c suppressing cell migration. This aimed to investigate the effect miR-200b on line its influence metastasis ability vitro. MATERIAL AND METHODS Breast lines MCF-7 MDA-MB-231 with different metastatic...

Previous studies found that iron accumulates in the substantia nigra of Parkinson's disease patients. However, it is still unclear whether other brain regions have accumulation as well. In this experiment, rats with rotenone-induced were treated by gastric perfusion baicalin or intraperitoneal injection deferoxamine. Immunohistochemical staining demonstrated accumulated not only pars compacta, but also significantly striatum globus pallidus, dentate gyrus granular layer hippocampus,...

Exendin-4, a glucagon-like peptide-1 receptor agonist, demonstrated cytoprotective actions beyond glycemic control in recent studies. The aims of the present study were to investigate effects exendin-4 on high glucose (HG)-induced cardiomyocyte apoptosis and possible mechanisms. Rat cardiomyocytes divided into 3 groups: normal group (NG group), HG +exendin-4 (HG+Ex Group). Cardiomyocyte was evaluated by double-staining with annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI)...
