05). CONCLUSIONS The degree of pain in pancreatic cancer is closely related to the pathological stage and expressions of NF-κB and COX-2, and the expressions of NF-κB and COX-2 are raised and the pain is aggravated as well in the patients at a higher pathological stage.PURPOSE Systemic inflammation plays a crucial role in carcinogenesis and progression of pancreatic cancer, due to its influence on tumor angiogenesis, invasion and metastasis. The association of CA 19-9, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) can identify patients with different prognoses. METHODS We reviewed 148 pancreatic cancer patients' charts diagnosed from January 2006 to December 2018 in a tertiary hospital. Cox proportional survival models were used to evaluate the impact of each factor on recurrence-free and overall survival (OS). RESULTS When assessing risk of relapse, the presence of angiolymphatic invasion was associated with an 80% chance of recurrence in 5 years. Among other factors associated with OS, the estimated risk of death in patients with CA 19-9>300 U/mL was 2.37-fold higher compared to lower values. In addition, the risk of death was 60% and 76% higher in patients with NLR>3 and PLR>150, respectively. Patients within these 3 categories had a median OS of only 7.5 months, lower than all-comer patients with stage IV disease, with median OS estimated at 9.84 months. CONCLUSION The laboratory variables CA 19-9, NLR and PLR together can contribute to a better stratification of patients with pancreatic adenocarcinoma beyond conventional staging. Prospective initiatives using these factors together can demonstrate different subgroups of patients who benefit from new treatment strategies.PURPOSE The main aim of the present study was to determine the antiproliferative effects induced by nootkatone-a plant sesquiterpene ketone along with determining its effects on autophagy, reactive oxygen species (ROS) production, cell cycle, cell migration and NF-κB signalling pathway. METHODS Cell proliferation of HXO-Rb44 human retinoblastoma cell line was evaluated by CCK-8 assay, while autophagic effects were evaluated by electron microscopy and western blot. Effects on cell cycle and ROS production were evaluated by flow cytometry. In vitro wound healing assay was used to determine the effects on cell migration. RESULTS The results indicated that nootkatone induced significant and dose-dependent cytotoxicity in HXO-Rb44 retinoblastoma cells with an IC50 value of 10.2 μM. Electron microscopy and western blot showed that nootkatone could induce autophagy as autophagosomes and vacuoles were seen to develop after nootkatone treatment. Autophagy was confirmed by observing the expression levels of LC3B-II, LC3B-I and p62. Nootkatone led to an increase of LC3B-II and LC3B-I but also led to inhibition of p62 expression. Nootkatone also led to increase of ROS production dose-dependently along with inducing S-phase cell cycle arrest. Nootkatone also led to inhibition of cell migration along with inhibiting NF-κB signalling pathway. CONCLUSIONS In conclusion, nootkatone molecule inhibits retinoblastoma by inhibiting Nf-κB signalling pathway and cell migration, autophagy induction, ROS generation and S-phase cell cycle arrest.PURPOSE The main purpose of the current study was to evaluate the anticancer action of 7-Methoxyheptaphylline in Y-79 human retinoblastoma cells along with evaluating its effects on cellular apoptosis, cell cycle phase distribution and Wnt/β-catenin signalling pathway. METHODS The retinoblastoma cell line RbY-79 was used in this study. Cell viability was assessed by WTS-1 assay while apoptotic studies were carried out by DAPI, acridine orange (AO)/ethidium bromide (EB), annexin V + propidium iodide (PI) staining using fluorescence microscopy and flow cytometry. Effects on cell cycle progression were studied using Annexin V/PI staining in combination with flow cytometry. Western blot assay was used to examine the effects on Bax, Bcl-2 and proteins associated with Wnt/β-catenin signalling pathway. RESULTS The results indicated that 7-Methoxyheptaphylline suppressed the viability of the Y-79 cells concentration-dependently with IC50 value of 15.5 μM. The percentage of the DAPI-positive cells showed a significant upsurge reminiscent of the apoptosis in the Y-79 retinoblastoma cells. 7-Methoxyheptaphylline also caused considerable nuclear fragmentation of the Y-79 retinoblastoma cells, representative of apoptosis. The apoptosis percentage increased significantly as the dose of the 7-Methoxyheptaphylline increased from 0 to 12, 24 and 48 µM. The molecule caused upregulation of Bax and downregulation of Bcl-2 in Y-79 retinoblastoma cells. 7-Methoxyheptaphylline also caused S-phase cell cycle arrest with concomitant concentration-dependent decline in the expression levels of cyclin A, E and D1. It was also seen that increasing doses of 7-Methoxyheptaphylline led to a dose-dependent decline in the expression levels of wnt-13a and β-catenin. CONCLUSIONS In conclusion, it is believed that the molecule may prove to be a promising anticancer agent for the treatment of retinoblastoma.PURPOSE The main purpose of the present research article was to investigate the anticancer properties of pectolinarigenin flavonoid in cisplatin-resistant hepatocellular carcinoma cells (SK-HEP-1) and normal liver cells (AML-12), along with examining its effects on autophagy, cell migration and invasion, cell cycle arrest and ERK1/2 MAP signalling pathways. METHODS Antiproliferative effects in cancer and normal cells were assessed by MTT cell viability assay. Cell autophagy effects were studied by electron microscopy as well as western blot. Effects on cell cycle were evaluated by flow cytometry using Annexin V/propidium iodide (PI) staining. Transwell migration assay and in vitro wound healing assay were performed to study the effects on cell migration and invasion, respectively. Epigenetic Reader Do inhibitor RESULTS The results indicated that pectolinarigenin inhibited significantly the growth of the SK-HEP-1 liver cancer cells and exhibited an IC50 of 10 µM, while against normal cells the cytotoxic effects were much less pronounced. Further, it was observed that the anticancer effects of pectolinarigenin were due to induction of autophagy which was also associated with upregulation of the expression of Beclin-1, LC3-I and LC3-II.
