Cancer-associated antigen 215 (CA215) is an immunoglobulin molecule expressed by numerous tumor types. Membrane‑bound and soluble CA215 have been detected in the majority of cancer cells and rarely identified in normal tissues. In addition, CA215C is a carbohydrate‑associated epitope in the variable region of CA215, which is specifically recognized by the monoclonal antibody, RP215. However, CA215C is not a suitable vaccine candidate as it is a thymus‑independent antigen. In the present study, RP215 was used as a target to screen short peptide mimics of CA215C from a phage display peptide library...

BACKGROUND: Anti-PD-1 therapy is increasingly used in various advanced malignancies. Patients with baseline organ dysfunction are largely excluded from clinical trials. Therefore it is unclear whether anti-PD-1 therapy is safe or effective in this setting. Further, these patients are often not candidates for other anti-cancer therapies, highlighting their need for active treatment options. METHODS: We performed a retrospective analysis of patients from multiple centers with advanced solid tumors and baseline organ dysfunction who received anti-PD-1 therapy...

Despite being the most common liver cancer in children, hepatoblastoma (HB) is a rare neoplasm. Consequently, few pre-treatment tumors have been molecularly profiled and there are no validated prognostic or therapeutic biomarkers for HB patients. We report on the first large-scale effort to profile pre-treatment HBs at diagnosis. Our analysis of 88 clinically-annotated HBs revealed three risk-stratifying molecular subtypes that are characterized by differential activation of hepatic progenitor cell markers and metabolic pathways: high-risk tumors were characterized by up-regulated NFE2L2 activity, high LIN28B, HMGA2, SALL4 and AFP expression, and high coordinated expression of oncofetal proteins and stem cell markers; while low-risk tumors had low LIN28B and let-7 expression, and high HNF1A activity...

Accumulating epidemiological evidence indicates that the quantitative changes in human mitochondrial DNA (mtDNA) copy number could affect the genetic susceptibility of malignancies in a tumor-specific manner, but the results are still elusive. To provide a more precise estimation on the association between mtDNA copy number and risk of diverse malignancies, a meta-analysis was conducted by calculating the pooled odds ratios (OR) and the 95% confidence intervals (95% CI). A total of 36 case-control studies involving 11,847 cases and 15,438 controls were finally included in the meta-analysis...

Studies have demonstrated the significant role of cholesterol and lipoprotein metabolism in the progression of cancer. The SCARB1 gene encodes the scavenger receptor class B type I (SR-BI), which is an 82-kDa glycoprotein with two transmembrane domains separated by a large extracellular loop. SR-BI plays an important role in the regulation of cholesterol exchange between cells and high-density lipoproteins. Accordingly, hepatic SR-BI has been shown to play an essential role in the regulation of the reverse cholesterol transport pathway, which promotes the removal and excretion of excess body cholesterol...

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...

: Bile acids (BAs) play critical physiological functions in cholesterol homeostasis and deregulation of BA metabolism causes cholestatic liver injury. Maternally expressed gene 3 (MEG3) was recently shown as a potential tumor suppressor, however its basic hepatic function remains elusive. Using RNA pull-down with biotin-labeled sense or anti-sense MEG3RNA followed by mass spectrometry, we identified RNA binding protein polypyrimidine tract-binding protein 1 (PTBP1) as a MEG3 interaction protein and validated their interaction by RNA immunoprecipitation (RIP)...

: Tissue-resident macrophages and bone marrow (BM)-derived monocytes play a crucial role in the maintenance of tissue homeostasis; however, their contribution to recovery from acute tissue injury is not fully understood. To address this issue, we generated an acute murine liver injury model using hepatocyte-specific Cflar-deficient (Cflar(Hep-low) ) mice. Cellular FLICE-inhibitory protein (cFLIP) expression was downregulated in Cflar-deficient hepatocytes, which thereby increased susceptibility of hepatocytes to death receptor-induced apoptosis...

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...

We previously showed that hepatitis B virus (HBV) X protein (HBx) could promote the trimethylation of histone H3 lysine 9 (H3K9me3) to repress tumor suppressor genes in hepatocellular carcinoma (HCC). In this work, we analyze 23,148 human promoters using ChIP-chip to determine the effects of HBx on H3K9me3 enrichments in hepatoma cells with transfection of HBx-expressing plasmid. Immunohistochemistry for HBx and H3K9me3 was performed in 21 cases of HBV-associated HCC tissues. We identified that H3K9me3 immunoreactivity was significantly correlated with HBx staining in HCC tissues...

BACKGROUND: Aggressive hepatectomy is effective in treating intrahepatic stones and may minimize the deleterious consequences of subsequent cholangiocarcinoma (S-CCA). The risk factors of S-CCA after different methods of hepatectomy may vary with the resection scope of stone-affected segments. METHODS: We reviewed the records of 981 patients of primary intrahepatic stones with elective hepatectomy from January 2000 to December 2010. The clinical characteristics of patients in the S-CCA group (n = 55) and the control group (n = 926) were compared...
