Background: Protein ubiquitination is a common post-translational modification involved in protein degradation and various life processes in cells. NEDL1 is a ubiquitin ligase that is highly expressed primarily in the brain. However, the functions of NEDL1 in social approach/novelty preference, anxiety, learning and memory remain poorly understood.

Background: To explore the efficacy of microwave ablation (MWA) in the treatment of hepatic alveolar echinococcosis (HAE) with a diameter of ≤5 cm.

Method: From June 2014 to January 2020, patients diagnosed with HAE were retrospectively analyzed. After balancing the confounding factors by propensity score matching (PSM) , the patients were divided into MWA group (n = 20) and radical operation group (n = 20) by 1:1 matching.

Echinococcosis is a worldwide neglected zoonotic disease. Alveolar echinococcosis (AE) poses a more serious threat to life and health than cystic echinococcosis, and has been one of the world's most lethal chronic parasitosis. Assessment of metacestode activity status is essential for individual treatment strategy design for a given AE patient, and fluorodeoxyglucose positron-emission tomography (FDG-PET) has been the gold standard.

Numerous studies have indicated that the neddylation pathway is closely associated with tumor development. MLN4924 (Pevonedistat), an inhibitor of the NEDD8-activating E1 enzyme, is considered a promising chemotherapeutic agent. Recently, we demonstrated that neddylation of the tumor suppressor PTEN occurs under high glucose conditions and promotes breast cancer development.

Purpose: Biliary leakage caused by cystobiliary communication (CBC) is a common clinical concern. This study sought to identify predictors of CBC in hepatic cystic echinococcosis (HCE) patients undergoing hydatid liver cyst surgery and establish nomograms to predict CBC.

Methods: A predictive model was established in a training cohort of 310 HCE patients diagnosed between January 2013 and May 2017.

Rationale: Hepatic alveolar echinococcosis (HAE) is a potentially fatal and chronically progressive infestation that is caused by the multivesicular metacestode of Echinococcus multilocularis (EM). HAE behaves like a malignant tumor and has been referred to as "worm cancer." The main treatment method for HAE is surgical resection.

The pretreatment nutritional and immunological status play indispensable roles in predicting the outcome of patients with various types of malignancies. The aim of the study was to investigate whether preoperative prognostic nutritional index (PNI), which simply accounts for nutritional and immunological status, was associated with overall survival (OS) in patients with gallbladder carcinoma (GBC). The retrospective study included a total of 315 GBC patients after surgery between 2002 and 2012.

Purpose: To evaluate the prognostic value of alkaline phosphatase (ALP) and gamma-glutamyltransferase (GGT) in gallbladder cancer (GBC).

Materials And Methods: Serum ALP and GGT levels and clinicopathological parameters were retrospectively evaluated in 199 GBC patients. Receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off values of ALP and GGT.

Protein ubiquitination plays vital roles in regulating various cytobiological processes such as cell cycle progression, DNA damage repair, signal transduction and membrane localization of various proteins. Moreover, proteins can be modified by single ubiquitin molecules (monoubiquitination) or ubiquitin chains (polyubiquitination). Polyubiquitination regulates protein function by linking different types of polyubiquitin chains to substrates.

Background: To compare the clinicopathological features and prognosis between younger and aged patients with hepatocellular carcinoma (HCC).

Methods: We analyzed the outcome of 451 HCC patients underwent liver resection, transcatheter arterial chemoembolization and radiofrequency ablation, respectively. Then risk factors for aged and younger patients' survival were evaluated by multivariate analysis, respectively.

Aim: To preliminarily investigate the prognostic significance of the platelet to lymphocyte ratio (PLR) in patients with gallbladder carcinoma (GBC).

Methods: Clinical data of 316 surgical GBC patients were analyzed retrospectively, and preoperative serum platelet and lymphocyte counts were used to calculate the PLR. The optimal cut-off value of the PLR for detecting death was determined by the receiver operating characteristic (ROC) curve.

Aim: To investigate the prognostic value of preoperative platelet count (PLT) in patients with primary gallbladder cancer (GBC).

Methods: The clinical data of 223 GBC patients after surgery was retrospectively reviewed. A receiver operating characteristic (ROC) curve was plotted to verify the optimum cutoff point for PLT.

Current cancer therapy mainly focuses on identifying novel targets crucial for tumorigenesis. The FoxM1 is of preference as an anticancer target, due to its significance in execution of mitosis, cell cycle progression, as well as other signal pathways leading to tumorigenesis. FoxM1 is partially regulated by oncoproteins or tumor suppressors, which are often mutated, lost, or overexpressed in human cancer.

Aim: To investigate the prognostic significance of estrogen receptor 1 (ER1) and vascular endothelial growth factor A (VEGF-A) expression in primary gallbladder carcinoma (GBC) to identify new prognostic markers for this malignancy.

Methods: Using immunohistochemistry, we investigated ER1 and VEGF-A expression in 78 GBC and 78 cholelithiasis (CS) tissues. The results were correlated with clinicopathological features.

The development of mammalian kidney is a complex process. The reciprocal inductive interactions between epithelial cells and metanephric mesenchymal cells determine cell fates including proliferation, growth, apoptosis, and eventually contribute to the formation of an intact kidney. Multiple signaling pathways, including the GDNF/Ret, Wnt and BMP signaling pathways, have been shown to regulate the development of kidney.

Article Synopsis
  • The study investigates how FoxM1, a transcription factor linked to cancer progression, affects the anti-cancer effects of sorafenib in hepatocellular carcinoma (HCC) cells.
  • Sorafenib was found to inhibit cell growth and invasion in HCC cell lines, showing a dose-dependent response and altering the expression of cancer-related proteins like FoxM1, MMP-2, Ki-67, and p53.
  • In animal studies, sorafenib reduced tumor growth significantly while altering protein expressions similarly to the in vitro findings, suggesting its potential as a treatment for HCC by targeting FoxM1.

Gallbladder carcinoma, the most frequent malignant neoplasm of the biliary tract system, has always been considered to feature late clinical presentation and diagnosis, limited treatment options and an extremely poor prognosis. In recent years, while the incidence of gallbladder cancer has appeared to be on the increase, the available treatment methods have not greatly improved survival of the affected patients. Thus, exploring new therapeutic targets for this devastating disease is an urgent matter at present.

Serum alpha-fetoprotein (AFP) is a significant marker for clinical diagnosis and prognosis evaluation in hepatocellular carcinoma (HCC) patients. However, some proportion of liver cancer patients are AFP-negative (AFP ≤20 ng/ml). In order to study the differences between clinicopathological factors and prognosis of alpha-fetoprotein negative and positive patients, a total of 114 cases (41 AFP-negative and 73 AFP-positive) were selected for our research.

Site- and state-specific lysine methylation of histones is catalyzed by a family of proteins including those contain the evolutionarily conserved SET domain. Research on histone methyltransferases is a part of epigenetics, which plays a fundamental role in heterochromatin formation, X-chromosome inactivation and transcription regulation. Aberrant histone methylation was linked to a number of developmental disorders and human disease including several carcinomas.

The zinc finger proteins containing the Kruppel-associated box domain (KRAB) constitute the largest single family of transcriptional regulators in mammals. Many genes encoding members of this family are arranged in clusters. KRAB-containing proteins are characterized by the presence of 4 and over 30 C2H2 zinc-finger motifs and a KRAB domain near the amino terminus of the protein.
