INTRODUCTION: Acute pulmonary embolism (APE) is a clinical syndrome of pulmonary circulation disorder caused by obstruction of the pulmonary artery or its branches. Histone deacetylase 6 (HDAC6) has been reported to play an important role in lung-related diseases. However, the functional role of HDAC6 in APE remains unclear. MATERIAL AND METHODS: Male Sprague Dawley rats were used. The APE model was constructed by inserting an intravenous cannula into the right femoral vein and injecting Sephadex G-50 microspheres (12 mg/kg; 300 µm in diameter)...

INTRODUCTION: . Focused ultrasound (FUS) is a non-invasive tumor therapy technology emerging in recent years, which can treat various solid tumors. However, it is unclear whether FUS can affect the pyroptosis of colon cancer (CC) cells. Here, we analyzed the effect of FUS on pyroptosis in the orthotopic CC model. MATERIAL AND METHODS: . After an orthotopic CC mouse model was constructed by injecting CT26-Luc cells, BABL/C mice were allocated to the normal, tumor, FUS, and FUS + BAY11-7082 (pyroptosis inhibitor) groups...

INTRODUCTION: Periostin (POSTN), an extracellular matrix protein, is involved in tumor-associated extracellular matrix (ECM) remodeling. However, its potential value as a prognostic and/or predictive factor has not yet been confirmed. The present study aims to assess POSTN expression separately in tumor cells and stroma of different ovarian carcinoma (OC) histological types, and its relationship with clinicopathological features. MATERIAL AND METHODS: 102 cases of different histological OC subtypes were immunohistochemically investigated, for POSTN expression assessment in both epithelial tumor cells and tumor stroma...

INTRODUCTION: As one of the basic components of Astragalus, Astragaloside IV (AS-IV) has a protective effect on endothelial injury caused by diabetes. AS-IV stimulated endothelial progenitor cells (EPCs) to secrete exosomes loaded with miR-21. This study aimed to investigate the effects of AS-IV-mediated EPCs exosomal miR-21 (EPC-exos-miR-21) on high glucose (HG) damaged endothelial cells. MATERIALS AND METHODS: After the isolation of EPCs derived from fetal umbilical cord blood, exosomes of EPCs were obtained by differential centrifugation...

INTRODUCTION: Adipogenesis, a highly coordinated process regulated by numerous effectors, is largely responsible for the quantity and size of adipocytes. Attenuation of adipocyte differentiation has been proposed as a viable technique for reducing obesity and its associated diseases. microRNAs play an important role in human bone marrow mesenchymal stem cells (hMSCs) adipogenic differentiation. However, there is a lack of clarity regarding the role of miR-328-5p in adipogenesis. MATERIAL AND METHODS: Using the lentiviral vectors to overexpress fatty acid synthase (FASN) and miR-328-5p, RT-qPCR and Western blotting were carried out to assess RNA expression and protein levels of FASN and adipogenic marker factors...

INTRODUCTION: Abnormal ovarian angiogenesis is a common feature of polycystic ovary syndrome (PCOS), a typical endocrine disorder affecting women of reproductive age. Histone deacetylase 5 (HDAC5) has been documented as a suppressor of angiogenesis. The aim of this study was to explore the effect of HDAC5 on ovarian angiogenesis in a PCOS mouse model. MATERIAL AND METHODS: PCOS was induced in female C57BL/6 mice by 20-day administration of dehydroepiandrosterone (DHEA)...

INTRODUCTION: Standard treatment for chronic lymphocytic leukemia (CLL) has experienced a dramatic change over the last few years. Until recently, CLL was treated using chemoimmunotherapy (CIT) with anti-CD20 monoclonal antibodies. Even though novel agents such as BTKi (Bruton Tyrosine Kinase inhibitor) and BCL2 inhibitors are the standard of care in most therapeutic settings, CIT still has its place in CLL treatment. Interestingly, little is known about its effects on the immune system of patients with CLL...

INTRODUCTION: The present study aimed to investigate the effect of homeodomain interacting protein kinase 2 (HIPK2) on pulmonary fibrosis and the probable mechanisms. MATERIAL AND METHODS: We constructed a mouse model of bleomycin-induced pulmonary fibrosis and up-regulated the expression of HIPK2 in the lung by in vivo transfection. Lung tissues were collected for the detection of mesenchymal markers (α-SMA, collagen I, collagen III, etc.) and the expression of β-catenin by RT-PCR, western blot, and immunohistochemistry...

INTRODUCTION: Peroxiredoxin 6 (Prdx6) is widely expressed in mammalian tissues. Our previous study demonstrated that Prdx6 was expressed in human epididymis, present in human seminal fluid, and in spermatozoa. The protective role of Prdx6 in maintaining the viability and DNA integrity of human spermatozoa was also detected. Here, we demonstrate the potential role and mechanism of Prdx6 in human epididymis epithelial cells (HEECs). MATERIAL AND METHODS: Western blotting was used to measure expression levels of key proteins in the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway...

INTRODUCTION: Evidence has shown that some microRNAs (miRNAs) play a role in tumorigenesis of hepatocellular carcinoma (HCC). Herein, we aimed to evaluate the diagnostic and prognostic values of serum exosomal miR-370-3p and miR-196a-5p in patients with HCC. MATERIAL AND METHODS: Serum exosomes in 90 HCC patients were extracted and identified. Serum exosomal miR-370-3p and miR-196a-5p expression in HCC patients were detected. The diagnostic value of miR-370-3p and miR-196a-5p, relationship between miR-370-3p and miR-196a-5p expression and clinicopathological features and prognosis of patients with HCC were analyzed...

INTRODUCTION: . Neuropeptide Y (NPY), a 36 amino acid neurotransmitter/neuromodulator, is involved in food intake and parental cares in birds. NPY is associated with the regulation of the reproductive system in the female native Thai chickens. However, the role of NPY in the male native Thai chicken has not been studied. Therefore, the objective of this study was to investigate the distributions of NPY immunoreactive (-ir) neurons and fibers in the brain of the male native Thai chickens...

INTRODUCTION: Glioma is characterized by hypoxia that activates the hypoxia inducible factor (HIF) pathway and controls a myriad of genes that drive cancer progression. HIF-1α promotes GLI1 transferring to the nucleus by activating the hedgehog pathway under hypoxic conditions. However, their mechanisms in glioma cells under hypoxia remain unknown. MATERIAL AND METHODS: Human glioma cell lines (LN229 and LN18) were transfected with HIF-1α or GLI1-specific short hairpin RNAs (shRNAs) and cultured under normoxic or hypoxic conditions...

INTRODUCTION: . Psoralen is a main active component of Psoralea corylifolia Linn. (Leguminosae). Psoralen has been reported to show antitumor effects and activity to accelerate osteoblastic proliferation. Nevertheless, the antitumor mechanism of psoralen in osteosarcoma has never been elucidated. The current study is aimed to investigate the therapeutic function of psoralen in human osteosarcoma cells and its potential regulatory mechanism. MATERIAL AND METHODS: Effects of psoralen (0-70 μg/mL) on the viability of two osteosarcoma cell lines cultured for 48 h was evaluated by MTT assays...
