macrophages promote hepatocellular carcinoma tumor stemness and progression through /β-catenin/ axis.

Liver cancer stem-like cells (LCSCs) are the main cause of heterogeneity and poor prognosis in hepatocellular carcinoma (HCC). In this study, we aimed to explore the origin of LCSCs and the role of the TOP2A/β-catenin/YAP1 axis in tumor stemness and progression. Using single-cell RNA-seq analysis, we identified LCSCs, which were mainly regulated by M2-like macrophages.

Single-cell RNA Sequencing Analysis Reveals New Immune Disorder Complexities in Hypersplenism.

Hypersplenism (HS) is a concomitant symptom of liver or blood disease. Not only does the treatment of HS face challenges, but the transcriptome of individual cells is also unknown. Here, the transcriptional profiles of 43,037 cells from four HS tissues and one control tissue were generated by the single-cell RNA sequencing and nine major cell types, including T-cells, B-cells, NK cells, hematopoietic stem cells, neutrophil cells, mast cells, endothelial cells, erythrocytes, and dendritic cells were identified.

[Inhibitory effect of NSC348884, a small molecular inhibitor of nucleophosmin, on the growth of hepatocellular carcinoma cell line hepG2].

Objective: To investigate the effect of NSC348884, a nucleophosmin small molecular inhibitor, on the growth of hepatocellular carcinoma cell line HepG2 and its underlying mechanism.

Methods: After HepG2 cells were treated by NSC348884 for 4 days, the effect of HepG2 cells on proliferation was measured by methyl thiazolyl tetrazolium (MTT) assay, the expression variation of nucleophosmin oligomer and monomer was measured using Western blotting, and cell apoptotic rate was detected by flow cytometry.

Results: The proliferation of HepG2 cells was remarkably inhibited by NSC348884 treatment when the drug concentration ranged from 1 micromol/L to 10 micromol/L (P < 0.

[Experience of surgical resection of Bismuth-Corlette type I and II hilar cholangiocarcinoma].

Objective: To report the experience of surgical resection of Bismuth-Corlette type I and II hilar cholangiocarcinoma.

Methods: From January 1998 and January 2008, 52 cases of Bismuth-Corlette type I and II hilar cholangiocarcinoma were operated on. The clinical data and long-term outcome of the patients was retrospectively analyzed.

[The advantages for Snail expression to promote cell migration and induce actin reorganization and to protect against the serum-deprivation-triggered apoptosis of bone marrow stem cells].

The Snail transcription factor has been described as a strong repressor of E-cadherin and its stable expression induces epithelial-mesenchymal transitions responsible for the acquisition of motile and invasive properties during tumor progression. A fascinating analogy that has been raised is the seemingly similar and shared characteristics of stem cells and tumorigenic cells, which prompted us to investigate whether the mechanisms of the acquisition of invasiveness during tumor progression are also involved in bone marrow stem cells (MSCs). In this study, we examined whether Snail gene expression acts in the mobility, cytoskeleton and anti-apoptosis of MSCs.

Zinc-finger transcription factor snail accelerates survival, migration and expression of matrix metalloproteinase-2 in human bone mesenchymal stem cells.

Although bone mesenchymal stem cells (BMSC) hold promise in gene therapy and tissue engineering, the inefficient migration and the low capability of subsequent survival of BMSC have largely restrained progress in these studies. Characteristics shared between stem cells and tumorigenic cells prompted us to investigate whether mechanisms of tumor progression contribute to stem cell migration. The transcription factor Snail which functions in epithelial-mesenchymal transitions (EMT) is responsible for the acquisition of motile and invasive properties of tumor cells.
