Hepatoblastoma (HB) is the most common malignant liver tumor among children. To gain insight into the pathobiology of HB, we performed RNA sequence analysis on 5 patient-derived xenograft lines (HB-243, HB-279, HB-282, HB-284, HB-295) and 1 immortalized cell line (HUH6). Using cultured hepatocytes as a control, we found 2,868 genes that were differentially expressed in all of the HB lines on mRNA level. The most upregulated genes were , , and , and the most downregulated were , , and . Protein-protein interaction analysis identified ubiquitination as a key pathway dysregulated in HB. , encoding an E2 ubiquitin ligase often overexpressed in cancer cells, was markedly upregulated in 5 of the 6 HB cell lines. Validation studies confirmed UBE2C immunostaining in 20 of 25 HB tumor specimens 1 of 6 normal liver samples. The silencing of in two HB cell models resulted in decreased cell viability. RNA sequencing analysis showed alterations in cell cycle regulation after knockdown. expression in HB correlated with inferior patient survival. We conclude that may hold prognostic utility in HB and that the ubiquitin pathway is a potential therapeutic target in this tumor.

Aim: To provide a theoretical basis for the study of the pathogenesis of residual dizziness (RD) from the perspective of imaging.
Materials And Methods: The general clinical data of the RD group and healthy control (HC) group were statistically analysed by two independent sample t tests, rank sum tests or chi-square tests. The imaging data of the two groups of people were preprocessed and statistically analysed by using the data processing and analysis for brain imaging (DPABI) software package.
Preoperative Anemia as a Prognostic Risk Factor for Inferior Oncological Survival Following Resection for Pancreatic Ductal Adenocarcinoma.
Pancreas
January 2025
Department of Surgery, Division of Hepato-Pancreato-Biliary Surgery and Liver Transplantation, University Medical Center Groningen, University of Groningen, the Netherlands.
Objectives: A significant proportion of patients undergoing surgery for pancreatic ductal adenocarcinoma (PDAC) are anemic at the time of resection. In these patients, blood transfusions are omitted due to their potential negative impact on oncological outcomes. The aim of the present study was to determine the prognostic value of preoperative anemia in resected PDAC patients, irrespective of blood transfusion status.

Purpose: Patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) have been noted to face increased cancer incidence. Yet, the impact of concomitant renal dysfunction on acute outcomes following elective surgery for cancer remains to be elucidated.
Methods: All adult hospitalizations entailing elective resection for lung, esophageal, gastric, pancreatic, hepatic, or colon cancer were identified in the 2016-2020 National Inpatient Sample.

Introduction: Allergic rhinitis is the specific inflammation against allergen by immune defense cells on the nasal mucosa, which can lead to chronic nasal symptoms such as sneezing, itching, runny nose, and nasal congestion. It is associated with high morbidity including sinusitis, asthma, otitis media, hypertrophied inferior turbinate, and nasal polyps. Despite its complications, it remains poorly recognized and tracked.

Colonic neuroendocrine tumors (NETs), excluding rectal NETs, are often described as relatively common and aggressive, with inferior median survival compared with other gastrointestinal (GI) primary sites. However, epidemiological databases may conflate well-differentiated NETs with poorly differentiated neuroendocrine carcinomas (NECs), leading to a lack of precise data on the prevalence, clinical behavior, and prognosis of well-differentiated colonic NETs. We analyzed a large institutional database to identify patients with well-differentiated NETs originating in the colon, excluding rectal NETs.
