Retinoblastoma (Rb) is the most common intraocular cancer of infancy and childhood, with an incidence of nearly 0.006% in all live births. Although a functional loss or inactivation of both alleles of the retinoblastoma 1 (RB1) gene during retinal development appears to be the predominant etiology for Rb, genes associated with tumor angiogenesis are also likely to be involved in the development of this condition. Netrin-1 is a factor that regulates pathological angiogenesis, while its role in Rb is largely unknown. The present study examined the role of netrin-1 in Rb.

The expression of netrin-1 in Rb was assessed using public databases and using clinical specimens by RT-qPCR for mRNA and by ELISA for protein. The expression of netrin-1 was suppressed in Rb by siRNA and the effects on cell growth were determined by a CCK-8 assay, while the effects on angiogenesis were examined

using human umbilical vein endothelial cell (HUVEC) assays and

by quantification of tumor vessel density.

Analysis of published databases revealed that the netrin-1 gene is significantly upregulated in Rb, which was confirmed by immunohistochemistry on clinical specimens. Inhibition of netrin-1 in Rb cell lines significantly reduced their effects on angiogenesis

using a HUVEC co-culture assay without affecting cell growth. Inhibition of netrin-1 expression

suppressed the growth of grafted Rb, and this effect could be abolished by co-expression of vascular endothelial growth factor A (VEGF-A).

This data demonstrated a novel role for netrin-1 in the regulation of Rb-associated cancer vascularization and may represent a novel therapeutic target for patients with Rb.

Propranolol is used clinically to treat infantile hemangioma (IH), although the exact mechanism that underlies its effectiveness is not fully understood. The Jagged1/Notch signaling pathway is downstream of the β2-adrenergic receptor (β2-AR). Propranolol is a non-selective β2-AR blocker that was shown to inhibit demethylation adrenaline-induced Jagged1 expression. A previous study has shown that propranolol dose-dependently inhibits the growth of IH. However, the effects of propranolol on stemness of IH are not known and are thus addressed in the current study.

We analyzed the expression of Jagged1 and Notch3 in IH specimens, using genetic tools to alter Notch signaling. The transduced IH cells were treated with different doses of propranolol, and the effects on IH cell proliferation, migration, and potential for tumor sphere formation were investigated. The effects of altered Notch signaling on tumor formation

were also assessed.

Notch3 and Jagged1 were significantly upregulated in IH. Augmented Notch signaling in IH cells increased cell proliferation, migration, the potential for tumor sphere formation and

tumor formation. On the other hand, reduced Notch signaling in IH cells decreased cell proliferation, migration, the potential for tumor sphere formation and

tumor formation.

Jagged1/Notch signaling regulated the stemness of IH, and propranolol inhibited it through suppression of Notch signaling.

To analyze the relationship between elastic characteristics and the expression of Smad2/3 in breast lesions.

Between April 2018 and October 2018, 135 lesions from 130 patients who underwent shear wave elastography before surgical excision or biopsy were included in the study. The shear wave elasticity features of the lesions, expression of Smad2/3 of the specimens, and their combined diagnostic efficacy was analyzed.

Of the 135 lesions, 51 were malignant and 84 were benign. The elasticity ratio of lesions to peripheral parenchyma, maximum elasticity, mean elasticity, prevalent rate of "stiff rim sign", and the expression level of Smad2/3 in the malignant pathological changes were obviously superior to those with benign pathological change (P<0.001). The Smad2/3 expression level had a positive correlation with the maximum, average elasticity, and the elastic ratio of lesions to peripheral parenchyma (r=0.657, 0.640, and 0.470, respectively, P<0.001). The expression of Smad2/3 in lesions with "stiff rim sign" was statistically higher than that in lesions without "stiff rim sign" (P<0.001). Moreover, the combination of Smad2/3 expression and "stiff rim sign" was shown to greatly raise the sensitivity (100%) and accuracy (94.56%) in the differential diagnosis of mammary gland disease.

In light of the findings, maximum, mean elasticity, elasticity ratio of lesions to peripheral parenchyma, and "stiff rim sign" are correlated with the expression of Smad2/3. The combination of the expression of Smad2/3 and "stiff rim sign" might contribute to the diagnosis of breast carcinoma.

Sepsis is a life-threatening condition of organ dysfunction caused by the host's disordered immune response to infection. It has a high fatality rate and seriously endangers human health. Rapid and accurate treatment plays an important role in the reduction of septic mortality. This study aimed to investigate the clinical value of hematological parameters neutrophil (NEU)-X, NEU-Y, monocyte (MON)-X, and MON-Y in sepsis, and compare their values with that of with C-reactive protein (CRP).

We collected dipotassium ethylenediaminetetraacetic acid (EDTA-K2) anticoagulant blood samples from a total of 267 patients with positive bacterial culture and 260 healthy physical check-up patients. Participants were divided into three groups a normal control group (n=260), bacterial infection group (n=196), and a sepsis group (n=71).

Median values of NEU-X, NEU-Y, MON-X, MON-Y, and CRP in the sepsis group were significantly higher than those in the control group and the bacterial infection group (P<0.0001). The area under the receiver operating characteristic curve (AUC) of NEU-X, NEU-Y, MON-X, MON-Y, and CRP for the diagnosis of sepsis was 0.751 (sensitivity 76.1%, specificity 58.2%), 0.877 (87.3%, 72.1%), 0.791 (77.6%, 65.9%), 0.695 (71.6%, 51.4%), and 0.790 (72.5%, 70.2%), respectively. In addition, blood smear examination results showed that NEU-X value was positively correlated with the degree of toxic granulation in neutrophils.

The parameters NEU-X, NEU-Y, and MON-X can be used as indicators for the differential diagnosis of sepsis with comparable diagnostic efficacy to CRP. Compared to CRP, these hematological parameters are easier to obtain, more convenient, and have economic benefits.

Long noncoding RNAs (lncRNAs) play a central role in the pathogenesis of various tumors, including hepatocellular carcinoma (HCC). TMPO antisense RNA 1 (TMPO-AS1) has been reported in many tumors. Nevertheless, the underlying mechanism whereby TMPO-AS1 influences HCC remains unclear. Our research aimed to reveal the molecular mechanism governing the function of TMPO-AS1 in HCC.

TMPO-AS1 expression levels in HCC tissues/cells were evaluated using reverse transcriptase-polymerase chain reaction. The effect of TMPO-AS1 on the progression of HCC was observed by Cell Counting Kit-8 (CCK8), clone formation, wound healing, and transwell. The direct interaction between TMPO-AS1 and microRNA (miR)-126-3p was observed using a dual-luciferase reporter.

We found TMPO-AS1 expression to be remarkably higher in HCC specimens and associated with poor prognosis. Silencing of TMPO-AS1 not only inhibited HCC cell proliferation but also significantly reduced epithelial-to-mesenchymal transition-induced invasion and migration to a remarkable degree. According to the results from the online database analysis tools implemented to identify if TMPO-AS1 could target miR-126-3p, we found that miR-126-3p had a negative relationship with TMPO-AS1 in HCC specimens. Meanwhile, the luciferase reporter assay confirmed that TMPO-AS1 could directly act on miR-126-3p. Moreover, the silencing of miR-126-3p dramatically abolish the inhibitive influence of sh-TMPO-AS1 on HCC development.

Our research demonstrated that TMPO-AS1 acts as a sponge for the tumor suppressor miR-126-3p in HCC and promotes the expression of LRP6 indirectly. Taken together, our results show that TMPO-AS1 may be regarded as a novel therapeutic target in the treatment of liver cancer.

Head and neck squamous cell carcinoma (HNSCC) is one of the most serious diseases affecting populations worldwide and lymph node metastasis is a key pathological feature of HNSCC which predicts poor survival. However, the molecular mechanisms associated with the development of lymph node metastasis in HNSCC have not been fully elucidated.

Differentially expressed genes (DEGs) were identified in two HNSCC datasets (GES6631 and GES58911). Functional annotation analysis was constructed via Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Meanwhile, the protein-protein interaction (PPI) network and module analysis using Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) and Cytoscape were carried out to identify the hub genes. The expression differences, overall survival (OS), and disease-free survival (DFS) of hub genes were analyzed by Gene Expression Profiling Interactive Analysis 2 (GEPIA2) and verified by immunohistochemistry (IHC) from may help to elucidate the molecular mechanisms of the development of lymph node metastasis and facilitate the selection of targets for the treatment and diagnosis of HNSCC.

The genes AURKA, CCNB1, CKS1B, SERPINH1, and TGFBI may be involved in the lymph node metastasis of HNSCC and reveal the potential to serve as molecular biomarkers in the diagnosis of HNSCC. This study may help to elucidate the molecular mechanisms of the development of lymph node metastasis and facilitate the selection of targets for the treatment and diagnosis of HNSCC.

The Breast Imaging Reporting and Data System (BI-RADS) category 4 breast lesions is categorized into 4A, 4B, and 4C, which reflect an increasing malignancy potential from low (2-10%) moderate (10-50%) and high (50-95%). Determining the benign and malignant of BI-RADS category 4 breast lesions is very important for accurate diagnosis and follow-up treatment. This study aimed to explore the value of breast magnetic resonance imaging (MRI) omics features and clinical characteristics in the assessment of BI-RADS category 4 breast lesions.

This retrospective study analyzed 96 lesions (39 benign and 57 malignant) from 92 patients diagnosed with MRI BI-RADS category 4 lesions in the Second Affiliated Hospital of Dalian Medical University between May 2017 and December 2019. The lesions were sub-categorized as BI-RADS 4A, 4B, or 4C based on the MRI findings. see more An imaging omics analysis model was applied to extract the MRI features. The positive predictive value (PPV) of each subcategory was calculated, and the area under the curve (AUC) was used to describe the efficiency for different diagnoses.
