Single high dose irradiation induces cell cycle arrest and apoptosis in human hepatocellular carcinoma cells through the Ras/Raf/MEK/ERK pathways.

Stereotactic body radiation therapy (SBRT) is emerging as a new noninvasive treatment in patients with primary liver carcinoma or liver-confined metastatic cancer. However, the radiobiological targets remain a subject of debate. Here, we investigated the potential biological effects of the radiation on the human hepatocellular carcinoma HepG2 cells.

Preparation of Engineered Extracellular Vesicles Derived from Human Umbilical Cord Mesenchymal Stem Cells with Ultrasonication for Skin Rejuvenation.

Extracellular vesicles (EVs) are lipid-bilayer-enclosed vesicles of submicron size that are secreted by various cells. As mediators of intercellular communication, EVs can alter the physiological state of recipient cells by delivering encapsulated proteins and nucleic acids. Incontestably, growing evidence has shown important biological roles and the clinical relevance of EVs.

Anti-LDLR modified TPZ@Ce6-PEG complexes for tumor hypoxia-targeting chemo-/radio-/photodynamic/photothermal therapy.

Hypoxia, a state of low oxygen tension in solid tumors, is not only closely correlated with resistance to both radiotherapy and chemotherapy, but also associated with poor prognosis of tumors and regional lymph node status. Herein, based on the analysis of cell samples from tumor patients, low-density lipoprotein receptor (LDLR) was found to be overexpressed on the surface of hypoxic tumor cell membranes, and confirmed to be an effective hypoxia marker through specific binding with anti-LDLR antibody in solid tumors. In addition, using the special therapeutic microenvironment of hypoxia, tirapazamine (TPZ, which can be used as both a hypoxia-activated chemotherapy prodrug and radiotherapy sensitizer) was integrated with PEGylated photosensitizer chlorin e6 (Ce6-PEG) by self-assembly, and anti-LDLR was then modified on the surface to form tumor hypoxia-targeting multifunctional nanoparticles (CPTA).

Ultrasound-guided percutaneous microwave ablation versus surgical resection for recurrent intrahepatic cholangiocarcinoma: intermediate-term results.

Objective: The aims of this study were to compare the clinical outcomes between ultrasound-guided percutaneous microwave ablation (US-PMWA) and surgical resection (SR) in patients with recurrent intrahepatic cholangiocarcinoma (ICC) and to identify the prognostic factors associated with the two treatment methods.

Methods: This retrospective study was institutional review board approved. A total of 121 patients (102 men and 19 women) with 136 ICCs after hepatectomy from April 2011 to January 2017 were reviewed.

Aptamer-Conjugated Extracellular Nanovesicles for Targeted Drug Delivery.

Extracellular nanovesicles (ENV) released by many cells contain lipids, proteins, and nucleic acids that contribute to intercellular communication. ENVs have emerged as biomarkers and therapeutic targets but they have also been explored as drug delivery vehicles. However, for the latter application, clinical translation has been limited by low yield and inadequate targeting effects.

Fine Particulate Matter and Sulfur Dioxide Coexposures Induce Rat Lung Pathological Injury and Inflammatory Responses Via TLR4/p38/NF-κB Pathway.

Fine particulate matter (PM) and sulfur dioxide (SO) are 2 common air pollutants, but their toxicological effects of coexposure are still not fully clear. In this study, SO exposure (5.6 mg/m) couldn't cause obvious inflammatory responses in rat lungs.

Synthesis of novel galactose functionalized gold nanoparticles and its radiosensitizing mechanism.

Background: Biocompatible gold nanoparticles (GNPs) are potentially practical and efficient agents in cancer radiotherapy applications. In this study, we demonstrated that GNPs can significantly modulate irradiation response of hepatocellular carcinoma cells in vitro and investigated the underlying mechanisms. We co-grafted galactose (GAL) targeting hepatocyte specific asialoglycoprotein receptor and Polyethylene Glycol (PEG) onto GNPs surfaces to increase GNPs targeting specificity and stability.

The role and mechanisms of nanoparticles to enhance radiosensitivity in hepatocellular cell.

Objective: This work aimed to investigate whether nanosilver and nanogold could modulate irradiation response of hepatocellular carcinoma cells (HepG2) in vitro and the underlying mechanisms.

Methods: Cell viability of the HCC cell lines (HepG2) was examined by the 3-(4,5-dimethylthiazol-yl)-5(3-carboxymethoxyphenyl)-2H-terazolium (MTT) assays. Clonogenic growth assays of HepG2 were determined by colony formation assays.

Nanoparticle surface and nanocore properties determine the effect on radiosensitivity of cancer cells upon ionizing radiation treatment.

For correctly selected and reasonably designed nanoscale radiosensitizers, it is necessary to investigate whether nanoparticle (NPs) coatings, nanocores (we defined it as naked NPs) or other precursors cause cellular response upon ionizing radiation (IR) at first. In this paper, we mainly discussed the effect of nanoparticle surface and nanocore properties on anti-proliferation of cancer cells upon IR treatment. We examined different kinds of modifiers of the same nanocores, as well as distinct nanocores with the same surface.

An oncolytic adenovirus regulated by a radiation-inducible promoter selectively mediates hSulf-1 gene expression and mutually reinforces antitumor activity of I131-metuximab in hepatocellular carcinoma.

Gene therapy and antibody approaches are crucial auxiliary strategies for hepatocellular carcinoma (HCC) treatment. Previously, we established a survivin promoter-regulated oncolytic adenovirus that has inhibitory effect on HCC growth. The human sulfatase-1 (hSulf-1) gene can suppress the growth factor signaling pathways, then inhibit the proliferation of cancer cells and enhance cellular sensitivity to radiotherapy and chemotherapy.
