CARD9 promotes cholangiocarcinoma by regulating the IL-17A/Hedgehog and the THEM4/AKT/mTOR signaling pathways.

Cholangiocarcinoma (CCA) is a highly lethal malignant tumor originating from the bile duct, and its underlying mechanisms are not fully understood. In order to identify key genes in CCA, we downloaded gene expression data from public GSE76297, GSE26566 and TCGA-CHOL datasets. CARD9 was selected as a CCA-related gene from the datasets.

Prognostic significance of regional lymphadenectomy in T1b gallbladder cancer: Results from 24 hospitals in China.

Background: Whether regional lymphadenectomy (RL) should be routinely performed in patients with T1b gallbladder cancer (GBC) remains a subject of debate.

Aim: To investigate whether RL can improve the prognosis of patients with T1b GBC.

Methods: We studied a multicenter cohort of patients with T1b GBC who underwent surgery between 2008 and 2016 at 24 hospitals in 13 provinces in China.

Both Talin-1 and Talin-2 correlate with malignancy potential of the human hepatocellular carcinoma MHCC-97 L cell.

Background: Talin-1 (TLN-1) and TLN-2 are implicated in many cellular processes, but their roles in hepatocellular carcinoma (HCC) remain unclear. This study aimed to assess cell cycle distribution, anoikis, invasion and migration in human HCC MHCC-97 L cells.

Methods: MHCC-97 L cells, which highly express TLN-1, were transduced with TLN-1 shRNA (experimental group) or scramble shRNA (negative control group); non-transduced MHCC-97 L cells were used as blank controls.

Talin-1 correlates with reduced invasion and migration in human hepatocellular carcinoma cells.

Background: Talin-1 is a cytoskeleton protein that participates in cell migration and plays a role in tumor formation, migration, and metastasis in different types of cancer. Chinese investigators have observed that the levels of Talin-1 protein and mRNA expression in HCC tissues are significantly lower than in the adjacent non-cancerous tissue. However, Japanese investigators have reported that Talin-1 is upregulated in HCC.

Talin1, a valuable marker for diagnosis and prognostic assessment of human hepatocelluar carcinomas.

Background/aims: Hepatocellular carcinoma (HCC) is one of the most lethal and prevalent cancers in the human population. Despite its significance, there is only limited understanding of pathological mechanisms and therapeutic options. Talin1, a focal adhesion complex protein that is required for cell adhesion and motility, regulates integrin interactions with extracellular matrix (ECM).

Promoter methylation and mRNA expression of DKK-3 and WIF-1 in hepatocellular carcinoma.

Aim: To investigate the promoter methylation status and mRNA expression of DKK-3 and WIF-1 gene in hepatocellular carcinoma (HCC).

Methods: DKK-3 and WIF-1 acted as Wnt-antagonists and tumor suppressors, but hypermethylation of the gene promoter and low mRNA expression activated Wnt signaling aberrantly and induced the development of HCC. Methylation status of the DKK-3 and WIF-1 gene promoter was investigated using methylation specific polymerase chain reaction (PCR) in tumor and adjacent non-cancerous tissues from 33 HCC patients and 20 normal liver tissues served as control.

[Clinicopathological significance of aberrant methylation of the fragile histidine triad gene in patients with hepatocellular carcinoma].

Objective: To investigate the aberrant methylation of fragile histidine triad (FHIT) gene and to explore possible relationship between the aberrant methylation of FHIT and clinicopathological features in hepatocellular carcinoma (HCC).

Methods: The hypermethylation of FHIT was detected by the methylation specific PCR (MSP) method in 45 patients with HCC (tumoral and nontumoral tissue), 14 cases of normal livers and 4 HCC cell lines (SK-Hep-1, Hep-G2, Hep-3B and Huh7). The correlation of FHIT methylation and clinicopathological features was analyzed.

Risk factors for biliary complications after liver transplantation.

Hypothesis: Biliary complications after liver transplantation can be predicted from perioperative factors.

Design: Retrospective analysis of data collected prospectively.

Setting: Tertiary referral center.

Multivariate regression analysis on early mortality after orthotopic liver transplantation.

Aim: To identify the risk factors relating to early mortality after orthotopic liver transplantation.

Methods: Clinical data of 37 adult patients undergoing liver transplantation were retrospectively collected and divided into two groups: the survived group and the death group (survival time<30 d). The relationship between multivariate risk factors and early mortality after orthotopic liver transplantation were analyzed by stepwise logistic regression.
