    Abstract Metastatic spread of hepatocellular carcinoma (HCC) to the spleen is uncommon, only occurring in approximately 1% of cases. Atraumatic splenic rupture due to HCC metastasis is extremely rare and affects patient prognosis, clinical management, and mortality. We report a case of a 65-year-old man with a history of chronic hepatitis B infection who presented with left-sided abdominal pain and fatigue. Clinical examination showed acute anemia with elevated levels of serum alpha-fetoprotein (AFP) and protein induced by vitamin K absence (PIVKA-II). On ultrasound and computed tomography imaging, hemoperitoneum caused by a ruptured splenic tumor was revealed. In addition to multiple hepatic… More >

    Abstract Sirtuins (SIRTs), members of the enzyme family found in yeast cells, are related to silent information regulator (SIR) 2 homologous to its gene family. SIRTs play an important role in many physiological functions from overexpression of gene silencing at the molecular level to the expression of related proteins and RNA to apoptosis. Studies have indicated that SIRTs may be related to the occurrence, development, and metastasis of cancer. However, the current mechanism of action of SIRTs in various diseases and the principle of molecular biology are not fully understood. Therefore, the present article discusses the main regulatory role and function… More >

    LI JIANG1,*, KE ZHANG1, CHONG HU1, HONGWEI ZHANG1, DANPU WANG1, WEIWEI ZHAI2

    BIOCELL, Vol.46, No.4, pp. 969-978, 2022, DOI:10.32604/biocell.2022.017765

    Abstract In recent decades, RNA binding motif (RBM) proteins have been widespread concerned by researchers. Among them, RBM5 is considered as a potential tumor suppressor gene in HCC. RBM10, also belonging to the RBM family, have similar structure and high homology with RBM5, indicating its potential as potential tumor suppressor genes. However, the role of RBM10 in tumors is controversial. The purpose of this study was to analyze the expression correlation and functional relationship of miR-21 and RBM10 in human hepatocellular carcinoma (HCC) tissues and corresponding tumor cells. Bioinformatics analysis showed that miR-21 and RBM10 were both highly expressed in HCC;… More >

    BIOCELL, Vol.46, No.2, pp. 401-415, 2022, DOI:10.32604/biocell.2022.016989

    Abstract Hepatocellular carcinoma (HCC) is a common immunogenic malignant tumor. Although the new strategies of immunotherapy and targeted therapy have made considerable progress in the treatment of HCC, the 5-year survival rate of patients is still very low. The identification of new prognostic signatures and the exploration of the immune microenvironment are crucial to the optimization and improvement of molecular therapy strategies. We studied the potential clinical benefits of the inflammation regulator miR-93-3p and mined its target genes. Weighted gene co-expression network analysis (WGCNA), univariate and multivariate COX regression and the LASSO COX algorithm are employed to identify prognostic-related genes and… More >

    XINGHONG YAO1,2,#, CHENGQUAN LU3,#, JUNYI SHEN1, WENLI JIANG1, YAN QIU1, YE ZENG1,*, LIANG LI1,*

    BIOCELL, Vol.45, No.6, pp. 1425-1448, 2021, DOI:10.32604/biocell.2021.017289

    Abstract Cancer stem cells (CSCs) are heterogeneous with self-renewal and differentiation ability. The mRNA expression-based stemness index (mRNAsi) described the similarity between tumor cells and CSCs, which is positively associated with the poor prognosis of cancer patients. However, the key prognostic genes related to mRNAsi in hepatocellular carcinoma (HCC) remains unclear. A 9-gene signature related to mRNAsi and HCC prognosis including PSMG3, SNRPD1, DTYMK, PIGU, NME1, TXNL4A, IPO4, PES1, and REXO4 was obtained. High expression of this signature indicates poor prognosis of HCC. PIGU was an independent prognostic factor of HCC, which was significantly associated with progression of HCC. Among them,… More >

    BIOCELL, Vol.45, No.6, pp. 1527-1541, 2021, DOI:10.32604/biocell.2021.016203

    Abstract PSMD14 played a vital role in initiation and progression of hepatocellular carcinoma (HCC). However, PSMD14 and its-related genes for the immune prognostic implications of HCC patients have rarely been analyzed. Messenger RNA expression profiles and clinicopathological data were downloaded from The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) database-Liver Hepatocellular Carcinoma (LIHC). Additionally, we used multi-dimensional bioinformatics analysis to construct and validate a PSMD14-based immune prognostic signature (including RBM45, PSMD1, OLA1, CCT6A, LCAT and IVD) for HCC prognosis prediction. Patients in the high-risk group shown significantly poorer survival than patients in the low-risk group. Calibration curves confirmed… More >

    HBx Downregulates miR-422a Expression via Activation of FOXG1/Q1/E1 in HepG2 Cells

    Xiaofan Deng1,2, Yamei Yang2,3, Xianfeng Gan2,3, Gang Wu2,3,*

    Oncologie, Vol.23, No.2, pp. 251-258, 2021, DOI:10.32604/Oncologie.2021.016900

    Abstract microRNA-422a (miR-422a) is downregulated in many hematopoietic tumors and solid tumors including hepatocellular carcinoma. We previously demonstrated that hepatitis B virus X protein (HBx) downregulated expression of miR-422a in HCC cell line HepG2 in vitro. However, we explore the mechanisms underlying this action. Forkhead box proteins (FOX) G1/Q1/E1 are known to negatively regulate miR-422a expression, and this prompted us to determine whether HBx suppresses miR-422a expression via activation of FOXG1/Q1/E1. The relationship between FOXG1/Q1/E1 and miR-422a in HepG2 cells stably expressing HBx was assessed with qRT-PCR. The correlation between HBx and FOXG1/Q1/E1 was determined with qRT-PCR and western blot in… More >

    Oncologie, Vol.22, No.1, pp. 35-42, 2020, DOI:10.32604/oncologie.2020.012485

    Abstract This study aimed to explore the expression and diagnostic performance of miR-586 and miR-493 in patients with osteosarcoma. We enrolled 63 patients with osteosarcoma treated between May 2016 and May 2019 as the experimental group and 55 healthy volunteers who underwent physical examination during the same period as the control group. We detected miR-586 and miR-493 expression in serum, normal bone tissue, and tumor samples. We also evaluated the relationship between clinical indicators and the miR-586 and miR-493 expression levels. The correlation between the serum and osteosarcoma tissue expression of miR-586 and miR-493 was examined by Pearson analysis. Furthermore, the… More >
