Collagen Triple Helix Repeat Containing 1 (CTHRC1) has been picked out as a cancer-related, secreted glycoprotein that possesses multifaceted functions such as wound repair, the formation of adipose tissue, hepatocytes fibrosis, and bone remodeling. This study aims to explore the biological function and the profound regulative mechanism of CTHRC1 in human prostate cancer (PCa). We found that CTHRC1 was upregulated in patients with PCa. The knockdown of CTHRC1 suppressed PCa cell proliferation, invasion, migration, and colony formation significantly. The expression of CTHRC1 was down-regulated and up-regulated by miR-30e-5p mimics and inhibitors, respectively, in PCa cells. The dual-luciferase reporter assay validated the binding of miR-30e-5p with CTHRC1 mRNA, indicating the regulation of CTHC1 by miR-30e-5p. In consequence, this study demonstrated that CTHRC1 acts as an oncogenic gene and targeting the miR-30e-5p-CTHRC1 axis may provide novel therapeutic treatment for PCa. Caspase recruitment domain 6 (CARD6) was initially implicated in the immune system and oncogenesis, which has also been emerged to play an important role in cardio-metabolic diseases. Nevertheless, the potential role of CARD6 on macrophage activation remains unknown. In the present study, we observed a decreased CARD6 expression in bone marrow derived macrophages (BMDMs) and mouse peritoneal macrophages (MPMs) isolated from ApoE deficiency mice and administrated with OX-LDL, which were tested by RT-PCR and western bolt analysis. Moreover, the immunofluorescence co-staining revealed that a weaker immunoreactivity of CARD6 was found and primary located in cytoplasm of macrophages induced by OX-LDL. Phenotypically, loss-of-function of CARD6 dramatically increased pro-inflammatory M1 macrophage but decreased resolving M2 macrophage markers expression. Additionally, CARD6 knockdown significantly promoted cholesterol uptake but attenuated cholesterol efflux, which lead to increased foam cell formation. Mechanistically, a downregulated AMP-activated protein kinase (AMPK) expression was required for the promoted effect of CARD6 knockdown on macrophage activation. Taken together, these results suggest that CARD6 protects against macrophage activation partially through activation of AMPK-dependent mechanism. Tumor necrosis factor receptor superfamily 19 (TNFRSF19) is a transmembrane protein involved in tumorigenesis. RAB43 is a small molecule GTP-binding protein contributing to the occurrence and development of tumors. However, TNFRSF19/RAB43 dysregulation and their role in hepatocellular carcinoma cells are unknown. Herein, we found that TNFRSF19 and RAB43 were downregulated in hepatocellular carcinoma tissues. TNFRSF19/RAB43 overexpression suppressed, whereas TNFRSF19/RAB43 knockdown promoted cell proliferation and epithelial-mesenchymal transition (EMT) of hepatocellular carcinoma cells. Previously, using deep sequencing technology, a new miRNA, miR-HCC3, was identified and found to suppress the expression of TNFRSF19 and RAB43 by binding to their 3'untranslated regions (3'UTRs) directly. miR-HCC3 was upregulated in hepatocellular carcinoma (HCC) tissues compared with adjacent noncancerous tissues and promoted proliferation and epithelial-mesenchymal transition in HCC cells. Furthermore, TNFRSF19/RAB43 suppressed but miR-HCC3 promoted tumor growth in vivo. Collectively, our results indicated that downregulation of TNFRSF19 and RAB43 by miR-HCC3 contributes to oncogenic activities in HCC, which sheds light on tumorigenesis and might provide potential therapeutic targets for HCC. Increased proteolytic activity has been widely associated with skeletal muscle atrophy. However, elevated proteolysis is also critical for the maintenance of intracellular homeostasis. In this study, we aimed to investigate the significance of autophagy in obesity-induced muscle atrophy and clarify the mechanism involved. First, high-fat diet (HFD)-fed rats were administered vehicle or chloroquine (CQ), an autophagy inhibitor, and we found that HFD inhibited autophagic flux and reduced myofiber size and function in rats. Additionally, the expression levels of MyoD were decreased whereas those of Atrogin-1 were increased in rats fed a HFD. Sustained autophagy inhibition by CQ exacerbated HFD-induced muscular damage and changes in the expression of Atrogin-1 and MyoD. Similar effects were reproduced in vitro in myotubes, which exhibited increased levels of autophagy-related proteins, but the resultant autophagic flux was reduced following exposure to palmitic acid (PA)-conditioned medium. Moreover, PA significantly decreased MyoD levels and induced Atrogin-1 expression, leading to progressive myotube atrophy; this phenomenon was aggravated by CQ but alleviated by the autophagy activator rapamycin. Taken together, these in vivo and in vitro findings suggest that autophagic flux is blocked in skeletal muscle of individuals with high lipid, and autophagy mediates high lipid-induced muscle atrophy by affecting muscle degradation and regeneration. BACKGROUND The programmed death 1/programmed death-ligand 1 (PD-L1) pathway reportedly is as an important factor determining effects of immunotherapy; however, its prognostic impact is controversial, and its association with the surrounding immune microenvironment has not yet been elucidated. PATIENTS AND METHODS We retrospectively analyzed 126 patients with pathologic stage I non-small-cell lung cancer. Patients with lepidic-dominant adenocarcinoma were excluded. PD-L1 expression was evaluated with immunohistochemistry correlated with clinicopathologic features and surrounding immune microenvironment status, including CD4, CD8, regulatory T cells, and human leukocyte antigen class I. Factors affecting prognosis were assessed by Kaplan-Meier and Cox regression analyses. ML349 RESULTS Twenty-three (18.3%) patients were positive for PD-L1 expression. link2 No significant correlation was observed between PD-L1 expression and the surrounding immune microenvironment status. The PD-L1-positive group had a worse prognosis than the PD-L1-negative group (5-year recurrence-free survival rates, 63.4% vs. 81.0%; P = .061). Among surrounding immune cells, intratumoral CD8 status had the strongest impact on prognosis (P = .12). In the intratumoral CD8-high group, PD-L1 expression demonstrated no significant prognostic impact, whereas in the intratumoral CD8-low group, patients positive for PD-L1 demonstrated a significantly worse prognosis than those negative for PD-L1 (5-year recurrence-free survival rates, 41.7% vs. 78.6%; P = .034). Multivariable Cox regression analysis revealed that 'PD-L1-positive and intratumoral CD8-low' status was an independent prognostic factor (hazard ratio, 3.80; 95% confidence interval, 1.22-10.5; P = .023). CONCLUSIONS The prognostic impact of the PD-1/PD-L1 pathway may be distinct according to concurrent intratumoral CD8 status. BACKGROUND This study aims to investigate the antimicrobial ability and mechanism analysis of Lactobacillus species against carbapenemase-producing Enterobacteriaceae (CPE). METHODS Five Lactobacillus spp. strains and 18 CPE clinical isolates were collected. Their anti-CPE effects were assessed by agar well diffusion and broth microdilution assay, as well as time-kill test. Finally, the specific anti-CPE mechanism, especially for the effect of organic acids was determined using broth microdilution method. RESULTS All of five Lactobacilli isolates displayed the potent activity against most CPE isolates with mean zones of inhibition ranging 10.2-21.1 mm. The anti-CPE activity was not affected by heating, catalase, and proteinase treatment. Under the concentration of 50% LUC0180 cell-free supernatant (CFS), lactic acid, and mix acid could totally inhibit the growth of carbapenem-resistant Klebsiella pneumoniae (CPE0011), and acetic acid could inhibit 67.8%. In contrast, succinic acid and citric acid could not inhibit the growth of CPE0011. While we decreased the concentration to 25%, only lactic acid and mix acid displayed 100% inhibition. link3 In contrast, succinic acid, citric acid and acetic acid did not show any inhibitory effect. CONCLUSIONS Lactobacillus strains exhibit potent anti-CPE activity, and lactic acid produced by Lactobacillus strains is the major antimicrobial mechanism. V.RATIONALE AND OBJECTIVES To explore the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) intensity histogram metrics, relative to time intensity curve (TIC)-derived metrics, in patients with suspected lung cancer. MATERIALS AND METHODS This retrospective study enrolled 49 patients with suspected lung cancer on routine CT imaging who underwent DCE-MRI scans and had final histopathologic diagnosis. Three TIC-derived metrics (maximum enhancement ratio, peak time [Tmax] and slope) and eight intensity histogram metrics (volume, integral, maximum, minimum, median, coefficient of variation [CoV], skewness, and kurtosis) were extracted from DCE-MRI images. TIC-derived and intensity histogram metrics were compared between benignity versus malignancy using the Wilcoxon rank-sum test. Associations between imaging metrics and malignancy risk were assessed by univariate and multivariate logistic regression odds ratios (ORs). RESULTS There were 33 malignant lesions and 16 benign lesions based on histopathology. Lower CoV (OR = 0.2 per 1-SD increase, p = 0.0006), lower Tmax (OR = 0.4 per 1-SD increase, p = 0.005), and steeper slope (OR = 2.4 per 1-SD increase, p = 0.010) were significantly associated with increased risk of malignancy. Under multivariate analysis, CoV was significantly independently associated with malignancy likelihood after accounting for either Tmax (OR = 0.3 per 1-SD increase, p = 0.007) or slope (OR = 0.3 per 1-SD increase, p = 0.011). CONCLUSION This initial study found that DCE-MRI CoV was independently associated with malignancy in patients with suspected lung cancer. CoV has the potential to help diagnose indeterminate pulmonary lesions and may complement TIC-derived DCE-MRI metrics. Further studies are warranted to validate the diagnostic value of DCE-MRI intensity histogram analysis. RATIONALE AND OBJECTIVES Misdiagnosis of intracranial hemorrhage (ICH) can adversely impact patient outcomes. The increasing workload on the radiologists may increase the chance of error and compromise the quality of care provided by the radiologists. MATERIALS AND METHODS We used an FDA approved artificial intelligence (AI) solution based on a convolutional neural network to assess the prevalence of ICH in scans, which were reported as negative for ICH. We retrospectively applied the AI solution to all consecutive noncontrast computed tomography (CT) head scans performed at eight imaging sites affiliated to our institution. RESULTS In the 6565 noncontrast CT head scans, which met the inclusion criteria, 5585 scans were reported to have no ICH ("negative-by-report" cases). We applied AI solution to these "negative-by-report" cases. AI solution suggested there were ICH in 28 of these scans ("negative-by-report" and "positive-by-AI solution"). After consensus review by three neuroradiologists, 16 of these scans were found to have ICH, which was not reported (missed diagnosis by radiologists), with a false-negative rate of radiologists for ICH detection at 1.
