RNF5 exacerbates steatotic HCC by enhancing fatty acid oxidation via the improvement of CPT1A stability.

Non-alcoholic fatty liver disease (NAFLD) is expected to become the leading risk factor for liver cancer, surpassing viral hepatitis. Unlike viral hepatitis-related hepatocellular carcinoma (HCC), the role of excessive nutrient supply in steatotic HCC is not well understood, hindering effective prevention and treatment strategies. Therefore, it is crucial to identify key molecules in the pathogenesis of steatotic HCC, investigate changes in metabolic reprogramming due to excessive fatty acid (FA) supply, understand its molecular mechanisms, and find potential therapeutic targets.

TRIM45 facilitates NASH-progressed HCC by promoting fatty acid synthesis via catalyzing FABP5 ubiquitylation.

Non-alcoholic steatohepatitis (NASH) is rapidly surpassing viral hepatitis as the primary cause of hepatocellular carcinoma (HCC). However, understanding of NASH-progressed HCC remains poor, which might impede HCC diagnosis and therapy. In this study, we aim to identify shared transcriptional changes between NASH and HCC, of which we focused on E3 ligase TRIM45.

Cavin1 activates the Wnt/β-catenin pathway to influence the proliferation and migration of hepatocellular carcinoma.

Introduction And Objectives: Cavin1 is a cell membrane caveolin, with controversial function in different tumors. Meanwhile, the role of Cavin1 in hepatocellular carcinoma (HCC) progression remains unclear. In this study, we attempted to elucidate the significance of Cavin1 in HCC occurrence and progression.

LIM domain only 7 negatively controls nonalcoholic steatohepatitis in the setting of hyperlipidemia.

Background And Aims: Hyperlipidemia has been extensively recognized as a high-risk factor for NASH; however, clinical susceptibility to NASH is highly heterogeneous. The key controller(s) of NASH susceptibility in patients with hyperlipidemia has not yet been elucidated. Here, we aimed to reveal the key regulators of NASH in patients with hyperlipidemia and to explore its role and underlying mechanisms.

USP53 plays an antitumor role in hepatocellular carcinoma through deubiquitination of cytochrome c.

Despite of advances in treatment options, hepatocellular carcinoma (HCC) remains nearly incurable and has been recognized as the third leading cause of cancer-related deaths worldwide. As a deubiquitinating enzyme, the antitumor effect of ubiquitin-specific peptidase 53 (USP53) has been demonstrated on few malignancies. In this study, we investigated the potential antitumor role of USP53 in HCC.

A Novel Immune-Related Prognostic Signature Predicting Survival in Patients with Pancreatic Adenocarcinoma.

Pancreatic adenocarcinoma (PAAD) carries the lowest survival rate of all major organ cancers, which is of dismal prognosis and high mortality rate. Thus, the present study attempted to identify a few novel prognostic biomarkers and establish an immune-related prognostic signature which could predict the prognosis of PAAD. Four prognostic immune-related genes (IRGs) including S100A6, S100A10, S100A16, and SDC1 were screened by differentially expressed gene (DEG) identification and weighted gene coexpression network analysis (WGCNA).

In this study, we evaluated the safety and effectiveness of the technical application of indocyanine green (ICG) fluorescence imaging-guided laparoscopic right posterior hepatectomy.

Methods: Twenty-six patients who underwent ICG fluorescence imaging-guided laparoscopic right posterior hepatectomy at Hepatobiliary and Pancreatic Surgery Department of Zhongnan Hospital, Wuhan University, from June 2018 to December 2019, were included.

Exome sequencing identifies MXRA5 as a novel cancer gene frequently mutated in non-small cell lung carcinoma from Chinese patients.

Lung cancer has become the top killer among malignant tumors in China and is significantly associated with somatic genetic alterations. We performed exome sequencing of 14 non-small cell lung carcinomas (NSCLCs) with matched adjacent normal lung tissues extracted from Chinese patients. In addition to the lung cancer-related genes (TP53, EGFR, KRAS, PIK3CA, and ROS1), this study revealed "novel" genes not previously implicated in NSCLC.

PA1 and PA27853 biofilms were observed under optical microscope after staining and under SEM after treatment with sansanmycin at different dosages and combined treatment with sansanmycin and roxithromycin.

[Comparison of prognosis of small hepatocellular carcinoma patients with hepatitis B virus infection versus hepatitis C virus infection].

Objective: To compare the prognosis of small hepatocellular carcinoma patients with hepatitis B virus infection versus hepatitis C virus infection.

Methods: 413 patients receiving curative resections at Tianjin Cancer Hospital for small HCC (< or = 3 cm) from January 1997 to December 2003 were divided into four groups: HCV only (n = 75), HBV only (n = 251), HBV and HCV (n = 33), and neither HBV nor HCV (NBNC, n = 54). The preoperative status and postoperative recurrence were recorded.

Generation and application of polyclonal antibody against replication and transcription activator of Kaposi's sarcoma-associated herpesvirus.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma, the most common neoplasm in untreated HIV-1-infected individuals, and several B cell disorders. KSHV infection goes through lytic and latent phases, and the switch from latency to lytic replication is governed by viral replication and transcription activator (RTA). RTA consists of 691 amino acids, containing an N-terminal DNA-binding and a C-terminal activation domain.

In vivo pharmacokinetics of hesperidin are affected by treatment with glucosidase-like BglA protein isolated from yeasts.

Hesperidin is an abundant flavanone glycoside in citrus fruits and has been reported to possess a wide range of biological activities. However, hesperidin has poor bioavailability. Here, we tested the hypothesis that hesperetin found in chenpi will have a better bioavailability than hesperidin and that treatment of hesperidin with the glucosidase-like yeast Bg1A protein will increase its bioavailability.
