Treatment of RB1-intact hepatocellular carcinoma with CDK4/6 inhibitor combination therapy.

Hepatology 2021 Apr 30. Epub 2021 Apr 30.

Cancer Research Institute, Kanazawa University, Kanazawa, Ishikawa, 920-1192, Japan.

Synthetic CDK4/6 inhibitors exert anti-tumor effects by forcing RB1 in unphosphorylated status, causing not only cell cycle arrest but also cellular senescence, apoptosis and increased immunogenicity. These agents currently have an indication in advanced breast cancers, and are in clinical trials for many other solid tumors. Hepatocellular carcinoma (HCC) is one of promising targets of CDK4/6 inhibitors. Read More

Reconciling the Biological and Transcriptional Variability of Hepatoblastoma with Its Mutational Uniformity.

Cancers (Basel) 2021 Apr 21;13(9). Epub 2021 Apr 21.

Division of Hematology/Oncology, UPMC Children's Hospital of Pittsburgh, Pittsburgh, PA 15224, USA.

Hepatoblastoma (HB), the most common childhood liver cancer, is associated with seven distinct histologic subtypes and variable degrees of clinical aggressiveness and presentation. Yet it is among the least genomically altered tumors known, with about half of HBs showing mutation and/or dysregulation of the Wnt/β-catenin and Hippo pathways. This raises the question of how this mutational simplicity can generate such biological and histologic complexity. Read More

Uncommon indications for associating liver partition and portal vein ligation for staged hepatectomy: a systematic review.

Hepatobiliary Surg Nutr 2021 Apr;10(2):210-225

Hepatobiliary Surgery and Organ Transplantation Unit, Department of General Surgery and Organ Transplantation, Sapienza University of Rome, Rome, Italy.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) represents an innovative surgical technique used for the treatment of large hepatic lesions at high risk for post-resection liver failure due to a small future liver remnant. The most significant amount of literature concerns the use of ALPPS for the treatment of hepatocellular carcinoma (HCC), cholangiocarcinoma (CCC), and colorectal liver metastases (CRLM). On the opposite, few is known about the role of ALPPS for the treatment of uncommon liver pathologies. Read More

CRISPR/Cas9-mediated knockout of PIM3 suppresses tumorigenesis and cancer cell stemness in human hepatoblastoma cells.

Cancer Gene Ther 2021 Apr 16. Epub 2021 Apr 16.

Division of Pediatric Surgery, Department of Surgery, University of Alabama at Birmingham, Birmingham, AL, 35233, USA.

Hepatoblastoma remains one of the most difficult childhood tumors to treat and is alarmingly understudied. We previously demonstrated that Proviral Insertion site in Maloney murine leukemia virus (PIM) kinases, specifically PIM3, are overexpressed in human hepatoblastoma cells and function to promote tumorigenesis. We aimed to use CRISPR/Cas9 gene editing with dual gRNAs to introduce large inactivating deletions in the PIM3 gene and achieve stable PIM3 knockout in the human hepatoblastoma cell line, HuH6.

The in vitro effects of hepatoblastoma cells on the growth and differentiation of blasts in transient abnormal myelopoiesis associated with Down syndrome.

Leuk Res 2021 Mar 31;105:106570. Epub 2021 Mar 31.

Department of Pediatrics, National Defense Medical College, Tokorozawa, Saitama-ken, Japan.

Transient abnormal myelopoiesis (TAM) in neonates with Down syndrome, which spontaneously resolves within several weeks or months after birth, may represent a special form of leukemia developing in the fetal liver (FL). To explore the role of hepatoblasts, one of the major constituents of the FL hematopoietic microenvironment, in the pathogenesis of TAM, we investigated the influence of a human hepatoblastoma cell line, HUH-6, on the in vitro growth and differentiation of TAM blasts. In a coculture system with membrane filters, which hinders cell-to-cell contact between TAM blasts and HUH-6 cells, the growth and megakaryocytic differentiation of TAM blast progenitors were increased in the presence of HUH-6 cells.

Bioluminescence Measurement of Time-Dependent Dynamic Changes of CYP-Mediated Cytotoxicity in CYP-Expressing Luminescent HepG2 Cells.

Int J Mol Sci 2021 Mar 11;22(6). Epub 2021 Mar 11.

Chromosome Engineering Research Center, Tottori University, 86 Nishi-cho, Yonago 683-8503, Tottori, Japan.

We sought to develop a cell-based cytotoxicity assay using human hepatocytes, which reflect the effects of drug-metabolizing enzymes on cytotoxicity. In this study, we generated luminescent human hepatoblastoma HepG2 cells using the mouse artificial chromosome vector, in which click beetle luciferase alone or luciferase and major drug-metabolizing enzymes (CYP2C9, CYP2C19, CYP2D6, and CYP3A4) are expressed, and monitored the time-dependent changes of CYP-mediated cytotoxicity expression by bioluminescence measurement. Real-time bioluminescence measurement revealed that compared with CYP-non-expressing cells, the luminescence intensity of CYP-expressing cells rapidly decreased when the cells were treated with low concentrations of aflatoxin B1 or primaquine, which exhibits cytotoxicity in the presence of CYP3A4 or CYP2D6, respectively.
