Purpose: Hepatocellular Carcinoma (HCC) features a complex pathophysiology and unpredictable immunosuppressive microenvironment, which limit the effectiveness of traditional therapies and lead to poor patient outcomes. Understanding the immune characteristics of HCC is essential for elucidating the immune microenvironment and developing more effective treatments. This study investigates the role of Peptidyl-prolyl isomerase H (PPIH) in HCC by analyzing its expression, prognosis, methylation levels, and relationship with immune cell infiltration.

Rheumatoid arthritis (RA) is a chronic, inflammatory, systemic autoimmune disease characterized by cartilage, bone damage, synovial inflammation, hyperplasia, autoantibody production, and systemic features. To obtain an overall profile of the immune environment in RA patients and its association with clinical features, we performed single-cell transcriptome and T-cell receptor sequencing of mononuclear cells from peripheral blood (PBMC) and synovial fluid (SF) from RA patients, integrated with two large cohorts with bulk RNA sequencing for further validation and investigation. Dendritic cells (DCs) exhibited relatively high functional heterogeneity and tissue specificity in relation to both antigen presentation and proinflammatory functions.

Angiogenesis is necessary for carcinoma progression and is regulated by a variety of pro- and anti-angiogenesis factors. CircRNAs are RNA molecules that do not have a 5'-cap or a 3'-polyA tail and are involved in a variety of biological functions. While circRNA-mediated regulation of tumor angiogenesis has received much attention, the detailed biological regulatory mechanism remains unclear.

Background: Primary hepatic carcinoid tumor (PHCT) is rare and has unclear clinical characteristics and prognosis.

Methods: A retrospective study using data from the SEER database for patients diagnosed with PHCT used univariate and multivariate Cox models to screen for independent prognostic factors. The outcomes of patients in the surgical and nonsurgical groups were compared, and Propensity Score Matching (PSM) analysis was used to reduce confounder bias.

Recent studies have shown that cleavage and polyadenylation-specific factor 3 (CPSF3) is a promising antitumor therapeutic target, but its potential role in hepatocellular carcinoma (HCC) has not been reported. We explored the expression pattern of CPSF3 in HCC through bioinformatics analysis, quantitative polymerase chain reaction (qPCR) and western blot. The potential role of CPSF3 as a biomarker for HCC was evaluated by Kaplan-Meier analysis.

Background: Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and the third leading cause of cancer-related death. MicroRNAs and transcription factors (TFs) cooperate to regulate the same target gene, thus affecting the progression of HCC.

Methods: Differentially expressed miRNAs and mRNAs were screened.

Situs inversus totalis (SIT) is a rare congenital condition in which the usual position of the organs is reversed from left to right as a mirror image of the normal situation. Due to the abnormal transposition, this represents a technical challenge for the surgeon. In the present study, right hemihepatectomy via the anterior approach was performed for a 68-year-old hepatocellular carcinoma (HCC) patient with SIT.

Lenvatinib is a long-awaited alternative to sorafenib for the first-line targeted therapy of patients with advanced hepatocellular carcinoma (HCC). However, resistance to lenvatinib has also become a major obstacle to improving the prognosis of HCC patients. The underlying molecular mechanisms contributing to lenvatinib resistance in HCC are largely unknown.

Background: Chaperonin containing TCP1 subunits (CCTs) are important components in the folding of newly synthesized proteins and are involved in cell growth, proliferation, and apoptosis in eukaryotes. Accumulating evidence indicates that dysregulation of CCTs is involved in tumorigenesis. However, the roles of distinct CCTs in the occurrence and development of hepatocellular carcinoma (HCC) are largely unknown.

Rationale: Hepatocellular carcinoma (HCC) metastases to the zygomatic bone are extremely uncommon, and the treatment of target drugs against such case is unknown.

Patient Concerns: A 48-year-old male patient was admitted to our hospital under suspicion of an advanced liver tumor due to an increase in levels of alpha-fetoprotein (AFP) after radiofrequency ablation for independent nodule in his liver 1 month before. He had a hepatitis B virus (HBV) history for 20 years without treatment.

Background And Aims: A simple, safe, targeted, and efficient in vivo DNA delivery system is necessary for clinical-grade liver-targeted gene therapy in humans. Intravascular hydrodynamic gene delivery has been investigated in large animal models, but translation to humans has been hampered by its technical challenges, invasiveness, and potential for significant cardiovascular adverse events. We posited that intrabiliary delivery of DNA plasmids via ERCP-guided hydrodynamic injection could overcome these obstacles.

Background: Integrator complex subunit 6 (INTS6) was found to play a tumour suppressing role in certain types of solid tumours. In this study, we wanted to determine the expression level of INTS6 in hepatocellular carcinoma (HCC) and evaluate its clinical characteristics and mechanisms in HCC patients (Lui and Lu, European Journal of Cancer, 51:S94, 2015).

Methods: First, we used a microarray analysis to explore the mRNA expression levels in HCC and paired normal liver tissues; second, we used qRT-PCR to measure the INTS6 mRNA levels in a cohort of 50 HCC tissues and adjacent normal liver tissues; third, we used Western blot analyses to detect the INTS6 protein levels in 20 paired HCC and normal liver tissues; fourth, we used immunohistochemistry to determine the INTS6 expression levels in 70 archived paraffin-embedded HCC samples.

Unlabelled: The cancer microenvironment plays a central role in cancer development, growth, and homeostasis. This paradigm suggests that cancer fibroblasts support cancers, probably in response to stimuli received from the cancer cells. We aimed at investigating whether extracellular vesicles (EVs) can shuttle microRNA (miR) species between cancer-associated fibroblasts (CAFs) and cancer cells.

In this study, we aimed to determine whether the pseudogene integrator complex subunit 6 pseudogene 1 (INTS6P1) in plasma could be used as a novel approach to screen for and detect hepatocellular carcinoma (HCC). We explored the clinical role of INTS6P1: First, the expression level of INTS6P1 was measured in a cohort of 33 HCC tissue samples and adjacent normal liver tissue, next, the INTS6P1 expression was detected in the culture medium and tumor cells in a cellular experiment, and last, the diagnostic performance of INTS6P1 was examined in an independent cohort of 100 people. The expression level of INTS6P1 was remarkably downregulated in the HCC tissues compared with that in the normal liver tissues (p = 0.

The complex regulation of tumor suppressive gene and its pseudogenes play key roles in the pathogenesis of hepatocellular cancer (HCC). However, the roles played by pseudogenes in the pathogenesis of HCC are still incompletely elucidated. This study identifies the putative tumor suppressor INTS6 and its pseudogene INTS6P1 in HCC through the whole genome microarray expression.

Retinoic acid receptor-related receptor alpha (RORalpha) has been proven to play a tumor suppressive role in certain types of solid tumors. However, the clinical characteristic of RORalpha has not been reported by far. This study investigated the expression of RORalpha in hepatocellular carcinoma (HCC) and evaluated its relationship with clinical parameters and prognosis in HCC patients.
