Autophagy is a fundamental cell biological process that confers stress tolerance, limits damage, and sustains viability under adverse conditions. Defective autophagy is associated with diverse diseases. The study aimed to investigate the relationship between UNC51-like kinase 1 (ULK1) expression and clinicopathological characteristics as well as survival in patients with hepatocellular carcinoma (HCC). Expression levels of ULK1 in 55 paired HCC and paracancerous tissues were examined using immunohistochemistry. Although not statistically significant, the expression of ULK1 in adjacent peritumoural tissue was lower than those in HCC tissues (P = 0.113). Expression level of ULK1 was significantly associated with tumor size (P = 0.015) after adjusted for age, sex, histologic grade, cirrhosis and TNM. Survival analysis showed that patients with high ULK1 expression had worse survival time than those with low ULK1 expression (hazard rate = 2.684, 95% CI 1.029-7.006, P = 0.044). The findings of the present study provide evidence that ULK1 represents a potential novel prognostic biomarker for HCC patients and may play an important role during the progression of HCC. Source

MicroRNAs (miRNAs) act as an oncogene or a tumor suppressor by negatively regulating target genes. Genetic variants in miRNA genes confer susceptibility to cancer and risk of death in cancer patients. The aim of this study was to investigate whether miRNA polymorphisms were associated with survival in breast cancer patients. Five miRNA polymorphisms (miR-26a1 rs7372209, miR-125a rs12976445, miR-218 rs11134527, miR-423 rs6505162, and miR-608 rs4919510) were genotyped in 196 breast cancer patients. We found that miR-125a rs12976445 was significantly associated with survival in codominant, recessive, and dominant models. However, only association under the codominant model remained significant after adjustment for lymph node metastasis, TNM stage, estrogen receptor, and progesterone receptor. Furthermore, this effect remained in stratification analysis. In conclusion, our results provide evidence that miR-125a rs12976445 may serve as a prognostic biomarker for breast cancer. Further large-scale studies are required to confirm these findings. © 2014, E-Century Publishing Corporation. All rights reserved. Source

MicroRNA-200c (miR-200c) influences sensitivity to chemotherapy and radiotherapy in vitro. This study was designed to investigate the prognostic potential of serum miR-200c in patients with advanced esophageal squamous cancer (ESCC). The serum levels of miR-200c was assayed by quantitative RT-PCR in 157 healthy subjects and 157 patients with advanced ESCC who were treated with platinum-based chemotherapy. The serum levels of miR-200c in advanced ESCC patients was significantly increased compared with those in controls (P < 0.001). Serum miR-200c expression was significantly associated with TNM stage (P = 0.037) and treatment response (P = 0.021). Patients with high expression of serum miR-200c had a higher risk for death than those with low expression of serum miR-200c (adjusted hazard ratios = 1.665, 95% confidence intervals: 1.135-2.443, P = 0.009). In conclusion, serum miR-200c may serve as predictor of survival for advanced ESCC and provide information for personalized therapy in advanced ESCC. Source

Increasing evidence has demonstrated that microRNAs (miRNAs) are involved in colon cancer initiation and progression, and may serve as diagnostic and prognostic biomarkers for colon cancer. Here, we investigated the levels of miR-9-1, miR-203-3p, miR-221-3p, miR-342-3p, miR-491-5p and miR-503-5p in 90 pairs of colon cancer and adjacent normal tissues, and explored the relationship between their expression and clinical outcome of colon cancer. Five miRNAs (miR-203-3p, miR-221-3p, miR-342-3p, miR-491-5p and miR-503-5p) were dysregulated in colon cancer tissue (P < 0.05). The levels of miR-503-5p in larger tumors (≥ 6 cm) were higher than those in smaller ones (< 6 cm) (P = 0.031), while the levels of miR-203-3p and miR-491-5p in patients aged 70 years and older were higher than those in patients aged younger than 70 years (P = 0.019 and 0.049, respectively). The high levels of miR-221-3p (HR = 2.416, 95% CI 1.314-4.445, P = 0.005), miR-342-3p (HR = 1.807, 95% CI 1.003-3.253, P = 0.049) and miR-491-5p (HR = 1.868, 95% CI 1.032-3.384, P = 0.039) were significantly associated with worse survival time. Moreover, combination analysis of miR-221-3p, miR-342-3p and miR-491-5p expression revealed that patients with 3 highly expressed miRNAs had lower survival rates compared with those with zero-to-two highly expressed miRNAs (HR = 2.100, 95% CI 1.157-3.813, P = 0.015), especially those with TNM stages I and II (HR = 4.204, 95% CI 1.762-10.030, P = 0.001). Our results suggest that the three-miRNA signature may help doctors better predict prognosis and guide treatment decisions for colon cancer. Source

Sarcomatoid variant of anaplastic large cell lymphoma (ALCL) is an extremely rare variant of ALCL with an abnormal morphology and immunophenotype, which is easily misdiagnosed as a high-grade sarcoma, poorly differentiated cancer or melanoma. Here, we reported the case of a 7-year-old boy with a sarcomatoid variant of ALCL involving the right neck lymph node, and compared it with those of the reported cases. Source
