Even though ellagic acid has previously been valued in many models of cancer, so far its full mechanistic effect as a natural antiapoptotic agent in the prevention of type 2 diabetes complications has not been completely elucidated, which was the goal of this study. We fed albino rats a high-fat fructose diet (HFFD) for 2 months to induce insulin resistance/type 2 diabetes and then treated the rats with ellagic acid (10 mg/kg body weight, orally) and/or repaglinide (0.5 mg/kg body weight, orally) for 2 weeks...

Flubendazole (FLBZ) is a broad-spectrum benzimidazole anthelmintic used in pigs, poultry, and humans. It has been proposed as a candidate for development for use in elimination programmes for lymphatic filariasis and onchocerciasis in humans. Moreover, FLBZ has shown promise in cancer chemotherapy, particularly for neuroblastoma. This work investigated the hepatic carbonyl-reducing pathway of FLBZ in different species, including humans. Microsomal and cytosolic fractions were obtained from sheep, cattle, pig, hen, rat, and human liver...

Aberrant expression of Liver X receptor α (LXRα) has been frequently reported in various types of cancers excluding gastric cancer (GC). Moreover, the role of LXRα in human GC has not been previously reported. In this study, we investigated the effect of LXRα down-regulation on invasion and EMT of GC. The expression of LXRα in GC cell lines was detected by real-time PCR. The LXRα siRNA was transiently transfected into GC cells using Lipofectamine™ 2000 reagent. Subsequently, cell invasive ability was evaluated by Transwell assays...

INTRODUCTION: Upper GI bleeding remains one of the most common emergencies with a substantial overall mortality rate of up to 30%. In severe ill patients, death does not occur due to failure of hemostasis, either medical or surgical, but mainly from comorbidities, treatment complications, and decreased tolerated blood loss. Management strategies have changed dramatically over the last two decades and include primarily endoscopic intervention in combination with acid-suppressive therapy and decrease in surgical intervention...

: Hepatitis C infection is a common risk factor for the development of liver cancer. The molecular mechanisms underlying this effect are only partially understood. Here we show that the HCV protein NS5B directly binds to the tumor suppressor NORE1A (RASSF5) and promotes its proteosomal degradation. In addition, we show that NORE1A co-localizes to sites of HCV viral replication and suppresses the process. Thus, NORE1A has anti-viral activity which is specifically antagonized by NS5B. Moreover, the suppression of NORE1A protein levels correlated almost perfectly with elevation of Ras activity in primary human samples...

Cell-on-a-chip systems have become promising devices to study the effectiveness of new anticancer drugs recently. Several microdevices for liver cancer culture and evaluation of the drug cytotoxicity have been reported. However, there are still no proven reports about high-throughput and simple methods for the evaluation of drug cytotoxicity on liver cancer cells. The paper presents the results of the effects of the anticancer drug (5-fluorouracil, 5-FU) on the HepG2 spheroids as a model of liver cancer. The experiments were based on the long-term 3D spheroid culture in the microfluidic system and monitoring of the effect of 5-FU at two selected concentrations (0...

Certain cell types function as factories, secreting large quantities of one or more proteins that are central to the physiology of the respective organ. Examples include surfactant proteins in lung alveoli, albumin in liver parenchyma, and lipase in the stomach lining. Whole-genome sequencing analysis of lung adenocarcinomas revealed noncoding somatic mutational hotspots near VMP1/MIR21 and indel hotspots in surfactant protein genes (SFTPA1, SFTPB, and SFTPC). Extrapolation to other solid cancers demonstrated highly recurrent and tumor-type-specific indel hotspots targeting the noncoding regions of highly expressed genes defining certain secretory cellular lineages: albumin (ALB) in liver carcinoma, gastric lipase (LIPF) in stomach carcinoma, and thyroglobulin (TG) in thyroid carcinoma...

RATIONALE: The highest burden of liver cancer occurs in developing countries, where the use of herbal medicine (HM) is still widespread. Despite this trend, few studies have been conducted to report HM practices of patients with a hepatic tumor in the developing world. Hence, this study aimed to document the use of HM among patients with liver cancer in Peru. STUDY DESIGN AND METHODS: A comparative behavioral epidemiological survey was conducted among liver cancer patients attending the National Cancer Institute of Peru...

Several long non-coding RNAs (lncRNAs) have been investigated and found to be correlated with the behaviours and prognosis of hepatocellular carcinoma (HCC); Specifically, we revealed that the lncRNA UC001kfo was differentially expressed in HCC tissues compared with normal liver tissues using lncRNA microarrays, but its functional role in cancers, including HCC, has not yet been elucidated. The present study found that the expression of UC001kfo was upregulated in HCC tissues and cell lines in comparison with tumour-adjacent tissues and normal hepatocytes, respectively...

BACKGROUND & AIMS: Modulation of microRNA expression is considered for treatment of hepatocellular carcinoma (HCC). Therefore, we characterized the epigenetically regulated microRNA-449 family (miR-449a, miR-449b, miR-449c) with regards to its functional effects and target genes in HCC. METHODS: After transfection of miR-449a, miR-449b, and/or miR-449c, tumor-relevant functional effects were analyzed using in vitro assays and a xenograft mouse model. Binding specificities, target genes, and regulated pathways of each microRNA were identified by microarray analyses...

Periampullary carcinoma metastases are usually located at regional nodes, adjacent organs, liver or lung. On the other hand, metastatic penile cancer is uncommon. Penile metastasis usually originates from pelvic region with prostate and bladder being the most frequent primary location. We present a very rare case of periampullary carcinoma with penile metastasis in a 49-year-old man. He initially presented with early ampullary type periampullary carcinoma and had pyloric preserving pancreatoduodenectomy and adjuvant chemotherapy...

Inhaled titanium dioxide (TiO2) nanoparticles (NPs) can have negative health effects, and have been shown to cause respiratory tract cancer in rats. Inflammation has been linked to oxidative stress, and both have been described as possible mechanisms for genotoxicity of NPs, but rarely examined side-by-side in animal studies. In the present study, a wide range of complementary endpoints have been performed to study TiO2 P25 NP-induced genotoxicity in lung overload and non-overload conditions. Additionally, lung burden, inflammation, cytotoxicity and oxidative stress have also been evaluated in order to link genotoxicity with these responses...

: To promote drug accumulation and cell-killing ability at tumor tissue, we have prepared a stepwise targeted drug delivery system that can remain stealthy and long-circulating in the blood vessels, improve drug retention at extracellular stimuli, enhance cellular uptake through special targeting ligands, and then achieve rapid drug release to improve toxicity to tumor cells at intracellular stimuli. Herein, galactose-grafted, ultra-pH-sensitive drug carriers (POEAd-g-LA-DOX micelles), which could respond to both extracellular and intracellular pH, and combine with galactose-receptors in cell membrane, were constructed by a facile method, therefore achieving: (i) remaining stable at pH 7...

PURPOSE: To assess feasibility and safety of conventionally fractionated radiotherapy (cfRT) in patients with hepatocellular carcinoma (HCC). METHODS: Patients with histologically confirmed stage cT1-4, cN0-1 HCC and Child-Pugh Score (CPS) A or B disease were included in a phase I multicenter trial. Metastatic HCC were allowed if ≥90% of total tumor volume was located within the liver. Patients were enrolled onto five dose-escalation levels (54-70Gy in 2Gy fractions) based on a modified 3 + 3 design, with cohorts of five patients instead of three patients in dose levels 4 and 5...

BACKGROUND: Cinobufacin injection, also known as huachansu, is a preparation form of Cinobufacini made from Cinobufacin extract liquid. Despite that Cinobufacin injection is shown to shrink liver and gastric tumors, improving patient survival and life quality, the effective components in Cinobufacin remain elusive. In this study, we aim to screen antitumor components from Cinobufacin injection to elucidate the most effective antitumor components for treatment of liver and gastric cancers...

Colorectal neoplasm is considered to have a strong association with nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS), respectively. The relationship among NAFLD, MetS, and colorectal neoplasm was assessed in 1793 participants. Participants were divided into 4 groups based on the status of NAFLD and MetS. Relative excess risks of interaction (RERI), attributable proportion (AP), and synergy index (SI) were applied to evaluate the additive interaction. NAFLD and MetS were significantly correlated with colorectal neoplasm and colorectal cancer (CRC), respectively...

Liver cancer is one of the leading causes of cancer-related mortality worldwide. Magnetic resonance imaging (MRI) is a non-invasive imaging technique that is often used by radiologists for diagnosis and surgical planning. Analysis of a large amount of liver MRI data for each patient limits the radiologist's efficiency and may lead to misdiagnoses. The redundant MRI data, especially from dynamic contrast enhanced (DCE) sequences, is also a bottleneck in transmitting the images via the internet or PACS for remote consultancy in a reasonable amount of time...
