Translation plays an important role in the carcinogenesis of various human tumors. Paip1 and eIF4A1 are translation-associated proteins that mediate the function of eukaryotic initiation factor 4F complex. This study aimed to analyse the relationship between the expression status of Paip1 and eIF4A1 and clinicopathologic features in hepatocellular carcinoma (HCC). Immunohistochemical analysis was used to evaluate the expression status of Paip1 and eIF4A1. Two pathologists independently interpreted the immunostained slides. The prognostic value of Paip1 and eIF4A1 was evaluated by the Kaplan-Meier plotter. Among 173 HCC patients, 28 (16.1%) and 46 (26.6%) belonged in the Paip1 and eIF4A1 high-expression groups. High expression of Paip1 and eIF4A1 was associated with advanced TNM stage and more frequent vascular tumor invasion. Univariate analysis indicated that high Paip1 expression was associated with worse five-year overall survival (OS). Public dataset analysis by Kaplan-Meier plotter revealed that high mRNA expression of Paip1, and not of eIF4A1, was significantly associated with worse five-year OS and disease-free survival. Paip1 expression has a potential prognostic value in human HCC. Paip1 expression has a potential prognostic value in human HCC. Leptin is a small hormone of protein nature, it is strongly involved in the regulation of lipid metabolism and its functioning mechanism is not yet well known or whether or not it is actually secreted by cholangiocytes, nor if the biliary tree expresses its receptors. In the past, various studies have tried to correlate leptin levels with certain neoplasms. check details The aim of this study was to demonstrate that serum leptin values can become a new sensitive and specific serum marker for cholangiocarcinoma. Seventy-two patients with gallbladder stones, hepatolithiasis with benign biliary stenosis, cholangiocarcinoma, and a group of patients without hepato-biliary diseases were enrolled in the study. In all cases blood and bile samples were collected for evaluation of leptin levels and liver biopsies were performed to confirm diagnosis. In all patients, both ultrasound and cholangio-magnetic resonance imaging (MRI) were performed to complete the diagnostic procedure. Twenty-two patients were affected by cholangiocarcinoma, 50 by benign biliary disease (35 cholelithiasis and 6 hepatolithiasis and 9 by inflammatory biliary stenosis). The mean values of serum leptin in patients with cholangiocarcinoma were 19.28±8.76 ng/ml, significantly higher than those observed in non-neoplastic biliary diseases. Serum leptin levels might be a useful marker to differentiate patients with cholangiocarcinoma from those with biliary lithiasis and inflammatory stenosis.

U-74389G and ascorbic acid protect the cells from oxidation. This study aimed to depict their role in ischemia-reperfusion injury in a renal rat model. Sixty Wistars rats were randomized into six groups of 10 animals each. Group A Ischemia 30 min, reperfusion 60 min; Group B Ischemia 30 min, reperfusion 120 min; Group C Ischemia 30 min, ascorbic acid administration, reperfusion 60 min; Group D Ischemia 30 min, ascorbic acid administration, reperfusion 120 min; Group E Ischemia 30 min, U-74389G administration, reperfusion 60 min; Group F Ischemia 30 min, U-74389G administration, reperfusion 120 min. We then collected tissue and blood samples. Histology and the significantly decreased malondialdehyde and tumor necrosis factor-α levels indicated that ascorbic acid was superior to U-74389G, at pre-defined time intervals. Ascorbic acid and U-74389G ameliorated renal damage induced by ischemia-reperfusion injury, suggesting a therapeutic effect.
