The mutation status of KRAS is a significant biomarker in the prognosis of rectal cancer. This study investigated the feasibility of MRI-based radiomics in predicting the mutation status of KRAS with a composite index which could be an important criterion for KRAS mutation in clinical practice. In this retrospective study, a total of 127 patients with rectal cancer were enrolled. The 3D Slicer was used to extract the radiomics features from the MRI images, and sparse support vector machine (SVM) with linear kernel was applied for feature reduction. The radiomics classifier for predicting the KRAS status was then constructed by Linear Discriminant Analysis (LDA) and its performance was evaluated. The composite index was determined with LDA model. Out of 127 rectal cancer subjects, there were 44 KRAS mutation cases and 83 wild cases. https://www.selleckchem.com/products/yd23.html A total of 104 radiomics features were extracted, 54 features were filtered by linear SVM with L1-norm regularization and 6 features that had no significant correlations within them were finally selected. The radiomics classifier constructed using the 6 features featured an AUC value of 0.669 (specificity 0.506; sensitivity 0.773) with LDA. Furthermore, the composite index (Radscore) had statistically significant difference between the KRAS mutation and wild groups. It is suggested that the MRI-based radiomics has the potential in predicting the KRAS status in patients with rectal cancer, which may enhance the diagnostic value of MRI in rectal cancer.Tetraspanin CD151 was found to be upregulated in malignant cell types and has been identified as a tumor metastasis promoter. In this study, we aimed to examine the role of the CD151-integrin complex in lung cancer metastasis and the underlying mechanisms. CD151 QRD194-196 →AAA194-196 mutant was generated and used to transfect A549 human lung adenocarcinoma cells. We found that there was no significant difference in CD151 protein expression between CD151 and CD151-AAA mutant groups. In vitro, CD151-AAA mutant delivery abrogated the migration and invasion of A549 cells, which was promoted by CD151 gene transfer. Furthermore, CD151-AAA delivery failed to activate FAK and p130Cas signaling pathways. Western blot and immunohistochemical staining showed strong CD151 expression in lung cancerous tissues but not in adjacent normal tissues. Increased level of CD151 protein was observed in 20 of the patients and the positive rate of CD151 protein in specimens was 62.5% (20/32). In addition, CD151 was co-localized with α3 integrin at the cell-cell contact site in carcinoma tissues. These results suggested that the disruption of the CD151-α3 integrin complex may impair the metastasis-promoting effects and signaling events induced by CD151 in lung cancer. Our findings identified a key role for CD151-α3 integrin complex as a promoter in the lung cancer.Anaplastic thyroid carcinoma (ATC) is a rare but extremely lethal malignancy. However, little is known about the pathogenesis of ATC. Given its high mortality, it is critical to improve our understanding of ATC pathogenesis and to find new diagnostic biomarkers. In the present study, two gene microarray profiles (GSE53072 and GSE65144), which included 17 ATC and 17 adjacent non-tumorous tissues, were obtained. Bioinformatic analyses were then performed. Immunohistochemistry (IHC) and receiver operating characteristic (ROC) curves were then used to detect transmembrane protein 158 (TMEM158) expression and to assess diagnostic sensitivity. A total of 372 differentially expressed genes (DEGs) were identified. Through protein-protein interaction (PPI) analysis, we identified a significant module with 37 upregulated genes. Most of the genes in this module were related to cell-cycle processes. After co-expression analysis, 132 hub genes were selected for further study. Nine genes were identified as both DEGs and genes of interest in the weighted gene co-expression network analysis (WGCNA). IHC and ROC curves confirmed that TMEM158 was overexpressed in ATC tissue as compared with other types of thyroid cancer and normal tissue samples. We identified 8 KEGG pathways that were associated with high expression of TMEM158, including aminoacyl-tRNA biosynthesis and DNA replication. Our results suggest that TMEM158 may be a potential oncogene and serve as a diagnostic indicator for ATC.Acute focal cerebral ischemic stroke (IS) is a leading cause of morbidity and mortality worldwide. Acupuncture is an emerging alternative therapy that has been beneficial to acute brain ischemia. However, the underlying protective mechanism of its neuroprotective effect remains unclear. Human original circadian rhythm will be lost after IS, which seriously affects the quality of life and functional recovery of stroke patients. We hypothesize that acupuncture treats IS by regulating the balance of Clock and Bmal1. This study aims to explore the effect of acupuncture at acupoints GV20 and BL23 on neuroprotection and anti-apoptosis in middle cerebral artery occlusion (MCAO) rats and expression of apoptosis and circadian rhythm related proteins. Male Sprague-Dawley (SD) rats were randomly divided into five groups normal group (Normal), sham model group (Sham MCAO), MCAO model group (MCAO), sham electroacupuncture group (Sham EA) and electroacupuncture group (EA). The MCAO model was prepared by electrocoagulation.he expression levels of circadian proteins Clock and Bmal1 were upregulated in EA group while compared with MCAO group. Our study demonstrated that acupuncture exerted neuroprotective effect against neuronal apoptosis after stroke and the mechanism might be related with regulation of circadian rhythm proteins Clock and Bmal1.Immunopathological mechanisms of schistosomiasis, a debilitating parasitic disease, are still unclear. In this study, we investigated the involvement of CX3C chemokine ligand 1 (CX3CL1) and its sole receptor CX3CR1 in the development of liver fibrosis in schistosomiasis. The animal model of schistosomiasis was established by infection of C57BL/6 mice with Schistosoma japonicum cercariae; mice injected with carbon tetrachloride (CCl4) were used as positive control of liver injury. After 4 and 8 weeks, the degree of liver lesions was assessed by hematoxylin and eosin staining, serum levels of hyaluronic acid (HA) were analyzed by a chemiluminescence immunoassay, liver fibrosis was evaluated by immunohistochemistry analysis of α-smooth muscle actin (α-SMA) expression, and CX3CL1 and CX3CR1 expression in the liver was measured by immunohistochemistry and real-time PCR. The results showed that at 8 weeks after Schistosoma infection, serum HA levels were increased and α-SMA-expressing cells appeared in the liver, indicating fibrogenesis.
