Adipocytokines play an important role in adipose tissue homeostasis, especially in obesity-associated disorders such as non-alcoholic fatty liver and their complications including hepatocellular carcinoma (HCC). Although visfatin is an adipocytokine highly expressed in visceral fat that has been demonstrated to play a critical role in the progression of human malignancies, little is known about the role of visfatin in HCC associated with chronic hepatitis C virus (HCV) and hepatitis B virus (HBV) infection...

PURPOSE: This study aimed to study whether cancer cells possess distinguishing metabolic features compared with surrounding normal cells, such as increased glutamine uptake. Given this, quantitative measures of glutamine uptake may reflect critical processes in oncology. Approximately, 10 % of patients with colorectal cancer (CRC) express BRAF (V600E) , which may be actionable with selective BRAF inhibitors or in combination with inhibitors of complementary signaling axes. Non-invasive and quantitative predictive measures of response to these targeted therapies remain poorly developed in this setting...

BACKGROUND: Gastric cancer (GC) relapse can occur even if curative resection is achieved. Biomarkers predicting recurrence are needed to provide appropriate postoperative surveillance and perioperative therapeutic strategy. METHODS: A global expression profiling was performed using tissues from GC patients with synchronous liver-confined metastasis. Family with sequence similarity 46, member C (FAM46C), was identified as a candidate biomarker. mRNA expression analysis, direct nucleotide sequencing, bisulfite sequencing and copy number assays for FAM46C were performed with eleven GC cell lines...

Positron emission tomography (PET) or PET/computed tomography (CT) using (18)F-3'-fluoro-3'-deoxythymidine ((18)F-FLT) offers noninvasive assessment of cell proliferation in human cancers in vivo. The present review discusses the current status on clinical applications of (18)F-FLT-PET (or PET/CT) in digestive and abdominal oncology by comparing with (18)F-fluorodeoxyglucose ((18)F-FDG)-PET (or PET/CT). The results of this review show that although (18)F-FLT uptake is lower in most cases of digestive and abdominal malignancies compared with (18)F-FDG uptake, (18)F-FLT-PET can be used to detect primary tumors...

Small cell lung cancer (SCLC) is known for its metastatic potential. The most common sites are liver, adrenal, bone and brain. We report a case of a 37year old female patient, diagnosed with SCLC, presenting with gingival metastasis, an unusual metastatic site. Radiation therapy to the metastatic lesion to a dose of 20 Gray in 5 fractions over 5days was delivered which achieved haemostasis and good palliation. However, the patient expired in 2months owing to systemic metastasis.

Tripartite Motif-containing protein 24 (TRIM24) functions as an E3 ligase targeting p53 for ubiquitination, a histone 'reader' that interacts with a specific signature of histone post-translational modifications and a co-regulator of nuclear receptor-regulated transcription. Although mouse models of Trim24 depletion suggest that TRIM24 may be a liver-specific tumor suppressor, several studies show that human TRIM24 is an oncogene when aberrantly over expressed. This review focuses on the mechanisms of TRIM24 functions in oncogenesis and metabolic reprogramming, which underlie recent interest in therapeutic targeting of aberrant TRIM24 in human cancers...

BACKGROUND: HBV and HIV share similar transmission routes. Concurrent infection with the two viruses usually results in more severe and progressive liver disease, and a higher incidence of cirrhosis, liver cancer and mortality. Further, this co-infection may lead to cross-resistance between HIV and HBV drugs and increased liver injury, either due to direct hepatotoxicity or drug-related immune-reconstitution hepatitis. These challenges necessitate continuous surveillance for HBV among HIV infected individuals to guide patient management...

BACKGROUND: Hepatocellular carcinoma (HCC) has very high prevalence and associated-mortality. However, targeted therapies that are currently used in clinical practice for HCC have certain limitations, in part because of the lack of reliable and clinically applicable biomarkers that can be used for diagnosis and prognosis assessments and for the surveillance of treatment effectiveness. METHODS: Meta-analysis was used to analyze the integrated microarray data for global identification of a set of robust biomarkers for HCC...

Saracatinib, is a highly selective Src kinase inhibitor against all Src kinase family members and has demonstrated anti-cancer effects in preclinical models. Unfortunately, it has shown multiple adverse effects during its clinical trials, along with time-dependent inhibition of P450 enzymes. The major objective of this study was to identify reactive metabolites of saracatinib in vitro and in vivo. Four oxidative metabolites (M1-M4) were detected in rat and human liver microsomal incubation systems after exposure to saracatinib...

To investigate the potential oncogene promoting recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT), throughput RNA sequencing was performed in a subgroup of HCC patients. The up-regulated FAM83D in HCC tissues was found and further verified in 150 patients by real-time PCR and immunohistochemistry. FAM83D overexpression significantly correlated with high HCC recurrence rate following LT and poor HCC characteristics such as high AFP, poor differentiation. Of cancer stem cells (CSCs) markers, CD44 expression was effectively suppressed when FAM83D was knocked down by siRNA...

BACKGROUND: Early tumour shrinkage has been associated with improved survival in patients receiving cetuximab-based systemic chemotherapy for liver metastases from colorectal cancer (LM-CRC). We tested this hypothesis for previously treated LM-CRC patients receiving cetuximab (500 mg/m(2)) and triplet hepatic artery infusion (HAI) within European trial OPTILIV. METHODS: Irinotecan (180 mg/m(2)), 5-fluorouracil (2800 mg/m(2)) and oxaliplatin (85 mg/m(2)) were given as chronomodulated or conventional delivery...

Chemical toxicity is conventionally evaluated in animal models. However, animal models are resource intensive; moreover, they face ethical and scientific challenges because the outcomes obtained by animal testing may not correlate with human responses. To develop an alternative method for assessing chemical toxicity, we investigated the feasibility of using chemical-induced genome-wide expression changes in cultured human cells to predict the potential of a chemical to cause specific organ injuries in humans...

There is great skepticism in the capability of adenovirus vectors and oncolytic adenoviruses to reach specific organs or tumors upon systemic administration. Besides antibodies, the presence of CAR (coxsackie and adenovirus receptor) in human erythrocytes has been postulated to sequester CAR-binding adenoviruses, commonly used in gene therapy and oncolytic applications. The use of non-CAR-binding fibers or serotypes has been postulated to solve this limitation. Given the lack of integrins in erythrocytes and therefore of internalization of the CAR-bound virus, we hypothesized that the interaction of adenovirus type 5 (Ad5) with CAR in human erythrocytes could be reversible...

BACKGROUND: Micrometastasis (MM) in colorectal cancer (CRC) is not considered in tumour-node-metastasis (TNM) staging currently and also the prognostic significance of these occult tumoural cells is not proven yet. This study was designed to find whether MM to bone marrow (BM) and/or liver cause upstaging of the tumour according to conventional staging system and if it may alter the survival rate. METHODS: Thirty-eight CRC patients who were candidates of surgical procedure were enrolled in our cross-sectional study...

AIM: There is firm evidence of a relation between type 2 diabetes (T2DM) and increased risks of cancer at various sites, but it is still unclear how different antihyperglycaemic therapies modify site-specific cancer risks. The aim of this study was to provide a complete characterization of all possible associations between individual T2DM therapies, statin use and site-specific cancers in the Austrian population. METHODS: Medical claims data of 1 847 051 patients with hospital stays during 2006-2007 were used to estimate age- and sex-dependent co-occurrences of site-specific cancer diagnoses and treatment with specific glucose-lowering drugs and statins...

Lung cancer is the most common solid tumor and the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) represents the major histological subtype and accounts for about 80 % cases of lung cancer cases. Recently, lncRNA lncTCF7 was identified, which is highly expressed in hepatocellular carcinoma (HCC) tumors and liver cancer stem cells (CSCs). However, the role of lnTCF7 in NSCLC remains largely unknown. In this study, Gain- and loss-of-function studies demonstrated the critical role of lncTCF7 in promoting invasion and self-renewal in NSCLC cells...
