An antigen processing and presentation signature for prognostic evaluation and immunotherapy selection in advanced gastric cancer.

Objective: The aim of the study was to propose a signature based on genes associated with antigen processing and presentation (APscore) to predict prognosis and response to immune checkpoint inhibitors (ICIs) in advanced gastric cancer (aGC).

Background: How antigen presentation-related genes affected the immunotherapy response and whether they could predict the clinical outcomes of the immune checkpoint inhibitor (ICI) in aGC remain largely unknown.

Methods: In this study, an aGC cohort (Kim cohort, RNAseq, N=45) treated by ICIs, and 467 aGC patients from seven cohorts were conducted to investigate the value of the APscore predicting the prognosis and response to ICIs.

CD137 agonist induces gastric cancer cell apoptosis by enhancing the functions of CD8 T cells via NF-κB signaling.

Background: CD137 is a target for tumor immunotherapy. However, the role of CD137 in gastric cancer (GC), especially in inducing GC cell apoptosis, has not been studied.

Methods: Foxp3 and CD8 T cells in GCs were investigated using immunohistochemistry (IHC).

Downregulation of SLC5A8 inhibits hepatocellular carcinoma progression through regulation of Wnt/β-catenin signaling.

SLC5A8 has been shown to be associated with a large number of cancer progressions. However, the biological functions of SLC5A8 in hepatocellular carcinoma (HCC) remain largely unclear. Therefore, we performed this research to explore the functions of SLC5A8 in HCC progression.

Hydrogen-rich saline attenuates postoperative liver failure after major hepatectomy in rats.

Background/aims: A major hepatectomy occasionally lead to acute liver failure and death. We demonstrated the anti-oxidative and anti-inflammatory effects and functional mechanisms of hydrogen-rich saline (HS), a novel antioxidant, on an experimental model of rats after a partial hepatectomy (PH).

Methods: The rats underwent a 90% hepatectomy.

The preliminary experience in simultaneous treatment of rectal cancer and synchronous liver metastases with laparoscopy.

Background/aims: There is no consensus for laparoscopy first in patients with rectal cancer and synchronous liver metastases, whose metastases are confined to the liver. This study aimed to evaluate its indications for one-stage surgery in laparoscopy.

Materials And Methods: Eighteen patients with rectal cancer and synchronous liver metastases, who had undergone laparoscopic colorectal resection and simultaneous treatment for liver metastases, were retrospectively reviewed.

One-stage resection for Bismuth type IV hilar cholangiocarcinoma with high hilar resection and parenchyma-preserving strategies: a cohort study.

Background: Bismuth type IV hilar cholangiocarcinoma (HC) tumors are usually considered unresectable. The strategies of high hilar resection while preserving liver parenchyma can achieve potentially one-stage curative resection for this condition. The aim of the present study was to investigate the feasibility and safety of available strategies.

Overexpression of GOLPH3 is associated with poor clinical outcome in gastric cancer.

This study aims to investigate the expression and significance of GOLPH3 in human gastric cancer progression and prognosis. Using immunohistochemistry (IHC) and real-time reverse transcriptase polymerase chain reaction assay, we identified abnormally elevated expression of GOLPH3 in gastric cancer tissues compared to paired normal stomach mucosa tissues in 40 patients. In addition, the enzyme-linked immunosorbent assay (ELISA) was used to quantify serum GOLPH3 concentrations in the same 40 gastric cancer patients and 40 healthy individuals.

High expression of AP-4 predicts poor prognosis for hepatocellular carcinoma after curative hepatectomy.

The aim of this study was to evaluate the association between activating enhancer binding protein 4 (AP-4) tissue expression and patient prognosis in hepatocellular carcinoma (HCC). The levels of AP-4 mRNA and protein in tumor and para-tumor tissue were evaluated in 30 HCC cases by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Additionally, AP-4 protein expression in 112 HCC was analyzed by immunohistochemistry.

Simultaneous resection of abdominal cancer and synchronous pancreaticoduodenal metastasis: indications and literature review.

Objective: This study was aimed to identify the potential indications for simultaneous resection of abdominal cancer and synchronous pancreaticoduodenal metastasis (SRAPM) and improve the efficacy of SRAPM.

Methods: The data of 34 patients who underwent SRAPM were retrospectively reviewed. The intraoperative findings, morbidity and mortality, patterns of tumor invasion in the pancreas and duodenum, lymph node metastases, long-term outcomes and causes of death were evaluated.

High RSF-1 expression correlates with poor prognosis in patients with gastric adenocarcinoma.

Aim: To investigate the expression and prognostic significance of RSF-1 in gastric adenocarcinoma.

Methods: RSF-1 expression was analyzed using immunohistochemical staining on tissue samples from a consecutive series of 287 gastric adenocarcinoma patients who underwent tumor resections between 2003 and 2006.The relationship between RSF-1 expression, clinicopathological factors, and patient survival was investigated.

High expression of ADAM8 correlates with poor prognosis in hepatocellular carcinoma.

Objectives: To evaluate the association between ADAM8 tissue expression and patient prognosis in hepatocellular carcinoma (HCC).

Methods: ADAM8 expression was analyzed using immunohistochemical staining methods on tissue samples from a consecutive series of 105 HCC patients who underwent resections between 2000 and 2006. The correlation of ADAM8 expression and patients' clinicopathological parameters was evaluated.

Overexpression of HOXA1 correlates with poor prognosis in patients with hepatocellular carcinoma.

HOXA1 overexpression is sufficient for malignant transformation of nontumorigenic epithelial cells. It is known that HOXA1, which was upregulated in squamous cell carcinomas, affects both cell growth and death. The forced expression of HOXA1 in human breast cancer cells results in increased cell growth activity.

WWOX induces apoptosis and inhibits proliferation of human hepatoma cell line SMMC-7721.

Aim: To investigate the effects of the WWOX gene on the human hepatic carcinoma cell line SMMC-7721.

Methods: Full-length WWOX cDNA was amplified from normal human liver tissues. Full-length cDNA was subcloned into pEGFP-N1, a eukaryotic expression vector.

Comparison of laparoscopic vs open liver lobectomy (segmentectomy) for hepatocellular carcinoma.

Aim: To investigate the effects of laparoscopic hepatectomy for the treatment of hepatocellular carcinoma (HCC).

Methods: From 2006 to January 2011, laparoscopic hepatectomies were performed on 30 cases of HCC at Northern Jiangsu People's Hospital. During this same time period, 30 patients elected to undergo conventional open hepatectomy over laparoscopic hepatectomy at the time of informed consent.

Melanoma-associated antigen family protein-D1 regulation of tumor cell migration, adhesion to endothelium, and actin structures reorganization in response to hypoxic stress.

Melanoma-associated antigen family protein-D1 (MAGE-D1) is a recently identified p75 neurotrophin receptor intracellular binding protein and functions as an adaptor that mediates multiple signaling pathways, including Dlx/Msx-mediated transcription. Here, a new regulatory function for MAGE-D1 in tumor cell motility and adhesion to endothelium is described. MAGE-D1 over-expression suppressed HeLa cell and BEL7402 cell migration, invasion, and adhesion to the monolayer of ECV304 cells.

Inhibition of adenovirus-mediated human MAGE-D1 on angiogenesis in vitro and in vivo.

MAGE-D1 is a member of the MAGE family of proteins, and functions as an adaptor that mediates multiple signaling pathways. The current study for the first time provides evidence for a role of MAGE-D1 in the negative regulation of angiogenic activity in vitro and in vivo models. Our findings showed that MAGE-D1 over-expression significantly suppressed the angiogenic key events such as endothelial cell migration and invasion, adhesion on collagen I substrate, and in vitro differentiation into tube-like structures under both normoxic and hypoxic conditions.
