With aging and other muscle wasting diseases, men and women undergo similar pathological changes in skeletal muscle: increased inflammation, enhanced oxidative stress, mitochondrial dysfunction, satellite cell senescence, elevated apoptosis and proteasome activity, and suppressed protein synthesis and myocyte regeneration. Decreased food intake and physical activity also indirectly contribute to muscle wasting. Sex hormones also play important roles in maintaining skeletal muscle homeostasis. Testosterone is a potent anabolic factor promoting muscle protein synthesis and muscular regeneration...

Treatment options for patients with hormone receptor-positive (HR+), HER2-negative (HER2-) breast cancer and resistance to endocrine therapy remain limited. An interesting therapeutic target in these patients is fibroblast growth factor receptor 1 (FGFR1). FGFR1 is amplified in approximately 11% of patients with breast cancer, especially those with HR+ disease. This report presents a patient with metastatic HR+ HER2- breast cancer harboring an FGFR1 amplification who was resistant to endocrine therapy but responded to pazopanib, a multi-tyrosine kinase inhibitor with FGFR-inhibiting activity...

The tyrosine kinase inhibitors sorafenib and imatinib are important in the treatment of a range of cancers but adverse effects in some patients necessitate dosage modifications. CYP3A4 has a major role in the oxidation of sorafenib to its N-oxide and N-hydroxymethyl metabolites and also acts in concert with CYP2C8 to mediate imatinib N-demethylation. CYP3A4 expression and function are impaired in patients with advanced liver disease, whereas the functions of CYP2C enzymes are relatively preserved. We evaluated the biotransformation of sorafenib and imatinib in well-characterized microsomal fractions from 17 control subjects and 19 individuals with hepatic cirrhosis of varying severity...

Hepatocellular carcinoma (HCC) chemoresistance, which is regarded as a kind of stress management reaction to chemotherapy drugs, severely hinders the therapy outcomes of HCC treatment. Stress management is generally achieved by activating certain signal pathways and chemical factors, among which, nuclear factor-E2-related factor2 (Nrf2) is a key factor in HCC chemoresistance formation. Nrf2 is a nuclear factor that coordinates the induction and expression of a battery of genes encoding cytoprotective proteins when participating in the Nrf2antioxidant response element (Nrf2/ARE) pathway, which is one of the most important intracellular antioxidant stress pathways...

A longitudinal molecular model of the development and progression of nonalcoholic fatty liver disease (NAFLD) over time is lacking. We have recently validated a high fat/sugar water-induced animal (an isogenic strain of C57BL/6 J:129S1/SvImJ mice) model of NAFLD that closely mimics most aspects of human disease. The hepatic transcriptome of such mice with fatty liver (8 weeks), steatohepatitis with early fibrosis (16-24 weeks) and advanced fibrosis (52 weeks) after initiation of the diet was evaluated and compared to mice on chow diet...

Background: Esophageal cancer is the eighth most common cancer worldwide. The prognosis of esophageal cancer patients is dismal, especially those with distant organ metastasis. However, there are few studies describing the patterns of distant metastasis in esophageal cancer systematically. Methods: We gathered the data from Surveillance Epidemiology and End Results (SEER) database between 2010 and 2013. Categorical variables were analyzed by the Pearson Chi square test, and continuous variables were analyzed by the two-sample t test...

Hepatocellular carcinoma (HCC) is the most commonly diagnosed malignancy of the liver. A more thorough understanding of HCC pathogenesis will provide novel targets for development of cancer drugs to effectively treat HCC. To further this goal, we carried out a proteomic profiling of HCC cell lines Huh-7.4 and Huh-7.5. These two cell lines were derived from subgenomic HCV RNA-replicating Huh-7 cells upon clearance of HCV RNA by antiviral drug treatment. Initially, the tumorigenicity of each cell line was determined and compared in parallel in the same immunedeficient mice...

Background and Aims: The multikinase inhibitor sorafenib is the only currently approved drug for the indication of advanced hepatocellular carcinoma (HCC). It provides a limited gain in survival time but is frequently associated with adverse events. We currently lack simple prognostic factors in sorafenib-treated HCC patients. Various inflammation-based scores (IBSs) have been evaluated as predictors of tumor recurrence and survival in various malignancies (including HCC). The objective of the present study was to determine the prognostic value of IBSs for overall survival (OS) in advanced HCC patients prior to the initiation of sorafenib therapy...

BACKGROUND: Serum vitamin B12 levels have been proposed as one of the survival prediction factors, although no survival analysis in metastatic cancer patients has been conducted yet. This study examined whether serum vitamin B12 levels could be a prognostic factor in metastatic cancer patients. METHODS: Data from a retrospective chart review were used to perform Kaplan-Meier and multivariate analyses of the Cox proportional hazards. Subgroup analysis was performed on patients without a liver lesion (hepatocellular carcinoma or liver metastasis)...

BACKGROUND: Response to opioids is not always positive in cancer patients. A considerable proportion of patients do not respond (non-responders, NRs) or experience severe toxicity. The aim of this analysis was to assess the role of demographic characteristics, pain features, comorbidities and ongoing therapy on the lack of efficacy and on the occurrence of severe adverse drug reactions (ADRs). METHODS: This is a post-hoc analysis of a randomized controlled trial that involved 520 patients and was aimed to evaluate the efficacy and safety of four strong opioids...

BACKGROUND: Nonalcoholic fatty liver disease, the hepatic manifestation of metabolic syndrome, is associated with increased risk of colorectal adenoma, a precursor of colorectal cancer. Because nonalcoholic fatty liver disease and colorectal adenoma share many common risk factors of metabolic syndrome, the association between these 2 pathological findings has been investigated in multiple studies, but the results have been conflicting. OBJECTIVE: The present study aimed to assess the relationship between the fatty liver index, a predictor of nonalcoholic fatty liver disease, and the prevalence of colorectal adenomas...

Colorectal cancer (CRC) is the third most common cause of cancer-related deaths worldwide. Hence there is a need to identify new therapeutic agents that improve the current repertoire of chemotherapeutic drugs. The antitumor activity of curcumin has been reported for several tumors, including CRC. A recent phase I trial showed that curcumin is safe and tolerable adjunct to FOLFOX (5-fluorouracil, folinic acid and oxaliplatin) chemotherapy in patient-derived colorectal liver metastases at doses up to 2 grams daily...

Overexpression of dominant oncogenes and the loss of tumor suppressor genes are basic genetic events in the acquisition of the malignant phenotype. The erb-b2 receptor tyrosine kinase 2 (ERBB-2) proto-oncogene is overexpressed in 20-30% of human breast cancers. The StAR related lipid transfer domain containing 13 gene (STARD13), also known as Deleted in Liver Cancer-2 (DLC-2), maps to chromosome band 13q12.3 and is frequently downregulated in human cancers, including 72% of breast cancers. It encodes a RhoGAP protein with sterile α motif (SAM) and StAR-related lipid transfer (START) domains...

BACKGROUND: Gallbladder cancer (GBC) has been contraindicated for laparoscopic surgery since this procedure was introduced [1, 2]. Recently, however, there have been several reports of laparoscopic extended cholecystectomy for GBC, but most cases involved early GBC confined to the GB [3, 4]. This video describes our technique of laparoscopic extended cholecystectomy for T3 GBC. METHODS: A 77-year-old female presented with a gallbladder mass, which was incidentally detected during evaluation of back pain...

High-mobility-group protein 2 (HMGB2) expression is upregulated in human liver cancer. However, little is known about its regulatory function. Here we establish HMGB2 as a new modulator of the pluripotency of mouse embryonic stem cells (ESCs). Similar to OCT4 and SOX2, HMGB2 protein is highly expressed in undifferentiated CGR8 cells, whereas it undergoes rapid decline during embryonic body (EB) formation. HMGB2 interacts with OCT4, increases protein expression of OCT4 and SOX2, and enhances their transcriptional activities...

UBE3A is an E3 ubiquitin ligase well known for its role in the proteasomal degradation of p53 in human papillomavirus (HPV)-associated cancers. Here we report that UBE3A ubiquitylates and triggers degradation of the tumor suppressive sirtuin SIRT6 in hepatocellular carcinoma. UBE3A ubiquitylated the highly conserved Lys160 residue on SIRT6. FOXO1-mediated transcriptional repression of UBE3A was sufficient to stabilize SIRT6 and epigenetically repress ANXA2, a key mediator of UBE3A oncogenic function. Thus, UBE3A-mediated SIRT6 degradation promoted the proliferative capacity, migration potential and invasiveness of cells...
