CD44V3, an Alternatively Spliced Form of CD44, Promotes Pancreatic Cancer Progression.

Pancreatic cancer is one of the most lethal malignant tumors. However, the molecular mechanisms responsible for its progression are little known. This study aimed to understand the regulatory role of CD44V3 in pancreatic cancer.

Intestinal obstruction due to idiopathic mesenteric phlebosclerosis colitis: A case report.

Introduction: Idiopathic mesenteric phlebosclerosis colitis (IMP) is a rare condition that impairs colonic venous blood return owing to mesenteric venous sclerosis and fibrosis. At present, many studies have suggested that long-term intake of Chinese herbal medicines is associated with its pathogenesis. IMP has no characteristic clinical manifestations, and most patients with IMP present with acute intestinal obstruction.

Light-activatable multifunctional paclitaxel nanoprodrug for synergistic chemo-photodynamic therapy in liver cancer.

Paclitaxel (Ptx) is widely utilized to treat liver cancer, and the treatment benefit of reactive oxygen species (ROS)-responsive Ptx nanoprodrug is investigated in this study. The one-step nano-precipitation method was utilized to self-assembly DSPE-PEG -thioketal linker (TK)-Ptx with pyropheophorbide acid nanoparticles (PPa NPs) to form PPa/Ptx NPs. Dynamic light scattering and transmission electron microscopy were used for characterization, and 2'-7'dichlorofluorescin diacetate staining was utilized for intracellular ROS detection.

Rapid enrichment and sensitive detection of extracellular vesicles through measuring the phospholipids and transmembrane protein in a microfluidic chip.

Extracellular vesicles (EVs) have attracted tremendous attention in recent years and quantification of EVs is a key issue in the evaluation of vesicle-based diagnostics and therapeutic development, but it's quite challenging to determine whether higher protein expression signals are due to larger vesicle amount or higher protein content within each vesicle. To solve this problem, herein, we proposed a strategy based on staining phospholipid bilayers of EVs with lipophilic dyes to evaluate their lipid amount, which was subsequently normalized as an internal standard for studying the expression of transmembrane protein (i.e.

C-X-C chemokine receptor 2 (Cxcr2) promotes hepatocellular carcinoma immune evasion via regulating programmed death-ligand 1 (PD-L1).

Strategies to sensitize hepatocellular carcinomas (HCC) to programmed death-1 (PD1)/programmed death-ligand 1 (PD-L1) inhibitor therapies are important in improving the survival of HCC patients. The aim of the study was to characterize C-X-C chemokine receptor 2 (Cxcr2) as a therapeutic target in HCC and evaluate the effects of Cxcr2 suppression in sensitizing HCC to PD1/PD-L1 inhibitor therapies. To this end, we constructed a Cxcr2-knockout HCC cell line (Hepa1-6 KO) using the CRISPR-Cas9 approach and assessed the tumor growth rate and survival of mice after subcutaneously inoculating Hepa1-6 KO cells in mice.

EIF3B promotes cancer progression in pancreatic cancer.

Background: This study aimed to analyze the relative expression of Eukaryotic Translation Initiation Factor 3 Subunit B (EIF3B) in pancreatic cancer and elucidate its contribution to this disease.

Methods: Relative expression of EIF3B in pancreatic cancer was analyzed by immunohistochemistry. Cell viability was determined by the MTT assay and cell proliferation was measured by direct cell counting.

Oxaliplatin induces immunogenic cell death in hepatocellular carcinoma cells and synergizes with immune checkpoint blockade therapy.

Background: Hepatocellular carcinoma (HCC) is one of the most common and devastating malignancies. Oxaliplatin, a platinum-based chemotherapeutic agent, is approved for the treatment of several malignancies, including HCC. However, its role in HCC is not well established.

LncRNA CYTOR promotes pancreatic cancer cell proliferation and migration by sponging miR-205-5p.

Background/aims: Studies have found that LncRNA CYTOR is an important regulator of cancer. However, the function of lncRNA CYTOR in pancreatic cancer (PC) is unclear. This study amid to explore the regulation of lncRNA CYTOR in PC.

Downregulation of orosomucoid 2 acts as a prognostic factor associated with cancer-promoting pathways in liver cancer.

Background: Liver cancer has a high mortality and morbidity rate throughout the world. In clinical practice, the prognosis of liver cancer patients is poor, and the complex reasons contribute to treatment failures, including fibrosis, hepatitis viral infection, drug resistance and metastasis. Thus, screening novel prognostic biomarkers is of great importance for guiding liver cancer therapy.

Specific Overexpression of Mitofusin-2 in Hepatic Stellate Cells Ameliorates Liver Fibrosis in Mice Model.

Liver fibrosis is a chronic liver disease that could further develop to cirrhosis and liver carcinoma. Hepatic stellate cells (HSCs) are primary effector cells to initiate liver fibrosis. We aimed to explore the function and underlying mechanisms of mitochondrial fusion protein Mitofusin-2 (MFN2) in liver fibrosis.

Downregulation of GNAI3 Promotes the Pathogenesis of Methionine/Choline-Deficient Diet-Induced Nonalcoholic Fatty Liver Disease.

Background/aims: The pathogenesis of nonalcoholic fatty liver disease (NAFLD) has not be fully elucidated, and the lack of therapeutic strategies for NAFLD is an urgent health problem. Guanine nucleotide binding protein, alpha inhibiting activity polypeptide 3 (GNAI3) participates in several biological processes, but its relationship with lipid metabolism and NAFLD has not yet been reported. We aimed to determine the function of GNAI3 in the development of NAFLD.

Growth inhibitor of human hepatic carcinoma HepG2 cells by evodiamine is associated with downregulation of PRAME.

Hepatocellular carcinoma (HCC) patients have low 5-year survival due to the delayed diagnosis, so it is necessary to develop an alternative treatment. Preferentially expressed antigen of melanoma (PRAME) has a high expression in HCC patients, and the effects of evodiamine on HCC are less characterized, although evodiamine has anti-tumor activities in several tumor types. To investigate the effects of evodiamine on PRAME expression, the in vitro PRAME expression in HepG2 cells after incubated with evodiamine was determined by RT-PCR and western blot.
