The fibrinolytic activity of 156 malignant and 36 benign solid tumors from autopsy and biopsy specimens was studied by the fibrin slide technique. The inhibitory activity against fibrinolysis was graded according to the lysis time of vascular tissues within the tumor. The results show that all malignant solid tumors, with the exception of prostate carcinoma, demonstrated varying degrees of inhibition of fibrinolysis. Persistently high inhibitory activity was found in squamous cell carcinoma of the esophagus, the respiratory tract, cervix uteri, and skin; carcinoma of uterus; colorectal carcinoma; small cell anaplastic carcinoma of lung; neuroblastoma, carcinoma of bile duct, while malignant tumors of the kidney show a lesser degree of inhibition. In contrast, with the exception of the hydatidiform mole, benign solid tumors show little or no inhibition. A similar absence of fibrinolytic activity is seen in metastatic disease. Further studies of the role of the fibrinolytic system in tumors seems warranted.

Human leukocyte antigen-G (HLA-G) is a novel tumor marker and its soluble isoforms produce secretory proteins. Increased soluble HLA-G (sHLA-G) levels have been reported in patients with melanoma, neuroblastoma, lymphoproliferative disorders, breast, ovarian and colorectal carcinoma when compared to healthy controls or subjects with benign neoplasms. The aim of this study is to investigate whether or not plasma sHLA-G can be used as a potential biomarker for cancer diagnosis. We measured plasma sHLA-G levels in 166 patients with early stages of colorectal cancer (CRC, n = 37), gastric cancer (GC, n = 28), esophageal squamous cell carcinoma (ESCC, n = 58) and non-small cell lung cancer (NSCLC, n = 43), and compared them to healthy controls (n = 260) by using a specific HLA-G enzyme-linked immunosorbent assay (ELISA). We found that plasma sHLA-G levels were significantly higher in cancer patients than in healthy controls (all P < 0.0001). The areas under the receiver-operating characteristic (ROC) curves for sHLA-G were 0.97, 0.91, 0.98 and 0.80 for healthy controls vs CRC, GC, ESCC and NSCLC, respectively. At 100% specificity, the highest sensitivity achieved to detect CRC, GC, ESCC and NSCLC was 94% [95% confidence interval (CI), 89-99], 85% (95% CI, 76-94), 91% (95% CI, 88-94) and 51% (95% CI, 43-59) at a cutoff value of 49 U/ml, respectively. These findings suggest that plasma sHLA-G may be a useful molecule in the differential diagnosis of these malignancies against healthy controls.

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive malignancies. Long noncoding RNAs (lncRNAs) have been identified to be associated with many diseases including tumors, and involved in the regulation of a wide array of pathophysiological processes. Small nucleolar RNA host gene 16 (SNHG16), also known as noncoding RNA expressed in aggressive neuroblastoma, was newly identified as a potential oncogene in many cancers. However, its role in ESCC has not been investigated. In the current study, the level of SNHG16 in the ESCC tissues and cell lines was measured by quantitative real-time PCR (qRT-PCR). Then loss-of-function assays were performed to explore the biological effects of SNHG16 in ESCC cell. Based on the online database analysis tools, we uncovered that miR-140-5p could interact with SNHG16 and the level of miR-140-5p was inverse correlated with SNHG16 in ESCC specimens. Moreover, RIP, RNA pulldown system and dual luciferase reporter assay further provided evidence that SNHG16 directly targets miR-140-5p by binding with microRNA binding site harboring in the SNHG16 sequence. Furthermore, bioinformatics analysis revealed that ZEB1 is a target of miR-140-5p in ESCC. Collectively, our findings suggested that SNHG16 could act as an oncogenic lncRNA that promotes tumor progression through acting as an endogenous 'sponge' by competing with miR-140-5p, thereby regulating target ZEB1.
