More than 90% of oral cancers are histopathologically squamous cell carcinomas (SCCs). According to clinical behavior and histopathological features, we hypothesize that oral SCC can originate from either oral squamous epithelium or minor salivary glands. Here, we examined whether some oral SCCs originate from minor salivary glands, and investigated whether these tumors show particularly aggressive biological behavior. The mRNA expression profiles of samples obtained from six patients with oral floor SCC (five men, one woman; mean age, 62...

We measured the content of HIF-1α and HIF-2α-immunopositive neurons and microvessels in the brain of Wistar rats during the first 24 h of tissue hypoxia induced by subcutaneous injection of cobalt dichloride (50 mg/kg). In control rats (without hypoxia), immunohistochemical marker HIF-2α in cortex of parietal lobe was not detected, and HIF-1α was detected only in few weakly stained pale neurons and capillaries. In 30 min after injection of the cobalt salt, the number of HIF-1α+ neurons increased by 25...

Genetic program regulating epithelial-mesenchymal transition is activated at the early stages of embryogenesis. Abnormal karyotype of the embryo disrupts the fundamental process of epithelial-mesenchymal transition, which is seen from incomplete morphological rearrangement and reduced migration capacity of cells, as well as low level of expression of epithelial-mesenchymal transition markers (fibronectin, collagen, and glycosaminoglycans). Disturbances of the epithelial-mesenchymal transition affect the proliferative potential of cells with aberrant karyotype, which contributes to the delay of embryonic development and correlates with the formation of abnormal phenotype in carriers of chromosomal abnormalities...

We studied the effect of SIRT1 deacetylase and PPARγ receptor activators on proinflammatory (M1), anti-inflammatory (M2) polarization of RAW264.7 macrophages and their modulating effects on insulin sensitivity of adipocytes. In M1 macrophages, the expression of TNFα and CXCL9, secretion of CXCL11, ROS generation, and content of dendritic-like cells were elevated. In M2 macrophages, expression of IGF-1 and ALOX15 factors was enhanced. SIRT1 activator (DCHC) and PPARγ receptor ligand (rosiglitazone) reduced expression of inflammatory markers TNFα and CXCL9 and increased expression of IGF-1 and ALOX15...

Acute respiratory distress syndrome (ARDS) is the most advanced form of acute lung injury (ALI). This is characterized by bilateral pulmonary infiltrates and severe hypoxemia. According to Berlin definition of ARDS, this is defined based on the timings, radiographic changes, edema formation, and severity on the PaO2 /FiO2 ratio. During ARDS, the loss of integrity of the epithelium causes the septic shock. The degree of epithelial injury is the major prognostic marker of ARDS. In addition to this, inflammatory cell migration, fibro-proliferation, and activation of apoptosis also play an important role in the pathophysiology of ARDS...

BACKGROUND: Lyme disease or Lyme borreliosis (LB) is the commonest vector-borne disease in the North America. It is an inflammatory disease caused by the bacterium Borrelia burgdorferi. The role of the inflammatory processes mediated by prostaglandins (PGs), thromboxanes and leukotrienes (LTs) in LB severity and symptoms resolution is yet to be elucidated. OBJECTIVES: We aim to systematically review and evaluate the role of PGs and related lipid mediators in the induction and resolution of inflammation in LB...

BACKGROUND: Analysis of cell-free fetal DNA in maternal plasma is very promising for early diagnosis of monogenic diseases. However, it has been limited by the need to set up patient- or disease-specific custom-made approaches. Here we propose a universal test based on fluorescent multiplex PCR and size fragment analysis for an indirect diagnosis of cystic fibrosis (CF). METHODS: The test, based on haplotyping, includes nine intra- and extragenic short tandem repeats of the CFTR locus, the coamplification of p...

BACKGROUND/AIMS: Liver progenitor cells (LPCs) were considered as a promising hepatocyte source of cell therapy for liver disease due to their self-renewal and differentiation capacities, while little is known about the mechanism of LPC differentiate into hepatocytes. This study aims to explore the effect of miR-382, a member of Dlk1-Dio3 microRNA cluster, during hepatic differentiation from LPCs. METHODS: In this study, we used rat liver progenitor cell WB-F344 as LPC cell model and HGF as inducer to simulate the process of LPCs hepatic differentiation, then microRNAs were quantified by qPCR...

BACKGROUND/AIMS: Lipopolysaccharides (LPSs) act as virulence factors that trigger intestinal inflammation and thereby compromise the production of pigs worldwide. Intestinal diseases and dysfunction have been attributed to endoplasmic reticulum stress (ERS) and the subsequent apoptosis of intestinal epithelial cells. Therefore It is important to explore whether LPSs aggravate ERS-mediated apoptosis of intestinal epithelial cells. METHODS: ERS and inflammation models were established in porcine cell line J2 (IPEC-J2) and the cells were treated with tunicamycin or LPS at specific times...

Patients with thyroid cancers refractory to radioiodine (RAI) treatment show a limited response to various therapeutic options and a low survival rate. The recent use of multikinase inhibitors has also met limited success. An alternative approach relies on drugs that induce cell differentiation, as the ensuing increased expression of the cotransporter for sodium and iodine (NIS) may partially restore sensitivity to radioiodine. The inhibition of the ERK1/2 pathway has shown some efficacy in this context. Aggressive thyroid tumors overexpress the isoform A of the insulin receptor (IR-A) and its ligand IGF-2; this IGF-2/IR-A loop is associated with de-differentiation and stem-like phenotype, resembling RAI refractory tumors...

Up to 80% of endometrial and breast cancers express oestrogen receptor alpha (ERα). Unlike breast cancer, anti-oestrogen therapy has had limited success in endometrial cancer, raising the possibility that oestrogen has different effects in both cancers. We investigated the role of oestrogen in endometrial and breast cancers using data from The Cancer Genome Atlas (TCGA) in conjunction with cell line studies. Using phosphorylation of ERα (ERα-pSer118) as a marker of transcriptional activation of ERα in TCGA datasets, we found that genes associated with ERα-pSer118 were predominantly unique between tumour types and have distinct regulators...

Analysis of cerebrospinal fluid (CSF) obtained by lumbar puncture (LP) is an essential step for the diagnostic approach of neurological disorders, in particular neuro-infections. In low-resource settings, it is even often the only available diagnostic method. Despite its key contribution, little is known on the risks and benefits of LP in the large tropical areas where hospital-based neuroimaging is not available. The objectives of this study were to assess the safety and diagnostic yield of LP in a rural hospital of central Africa and to identify predictors of CSF pleocytosis (white blood cell count >5/μL) as surrogate marker of neuro-infections...

Papillary renal cell carcinoma (PRCC) is currently divided in two subtypes. We reviewed a large cohort of PRCC and correlated subtype, morphological features and diagnostic marker expression with overall survival (OS) to uncover differences between the two subtypes. 376 renal tumors initially diagnosed as PRCC with clinical and survival data were collected from the participating centers. 246 tumors were classified as PRCC1 (65.4%) and 130 as PRCC2 (34.6%) and graded according to the 2016 World Health Organization/International Society of Urological Pathology grading system...

Cellular senescence is a stress response mechanism ensuring homeostasis. Its temporal activation during embryonic development or normal adult life is linked with beneficial properties. In contrast, persistent (chronic) senescence seems to exert detrimental effects fostering aging and age-related disorders, such as cancer. Due to the lack of a reliable marker able to detect senescence in vivo, its precise impact in age-related diseases is to a large extent still undetermined. A novel reagent termed GL13 (SenTraGorTM ) that we developed, allowing senescence recognition in any type of biological material, emerges as a powerful tool to study the phenomenon of senescence in vivo...

Chronic bladder obstruction and bladder smooth muscle cell (BSMC) stretch provide fibrotic and mechanical environments that can induce epigenetic change. Therefore, we examined the role of DNA methylation in bladder pathology and transcriptional control. Sprague-Dawley female rats underwent partial bladder obstruction by ligation of a silk suture around the proximal urethra next to a 0.9 mm steel rod. Sham operation comprised passing the suture around the urethra. After two weeks, rats were randomized to normal saline or DNA methyltransferase inhibitor, 5-aza-2-deoxycytidine (DAC) at 1 mg/kg, 3 times/week intraperitoneally...

OBJECTIVE: Major changes in the classification of ovarian carcinoma histotypes occurred over the last two decades, resulting in the current 2014 World Health Organization (WHO) diagnostic criteria that recognize five principal histotypes: high-grade serous, low-grade serous, endometrioid, clear cell, and mucinous carcinoma. We assessed the impact of these guidelines and use of immunohistochemical (IHC) markers on classification of ovarian carcinomas in existing population-based studies...

BACKGROUND: Ovarian cancer is a complicated malady associated with cancer stem cells (CSCs) contributing to 238,700 estimated new cases and 151,900 deaths per year, worldwide. CSCs comprise a tiny fraction of tumor-bulk responsible for cancer recurrence and eventual mortality. CSCs or tumor initiating cells are responsible for self-renewal, differentiation and proliferative potential, tumor initiation capability, its progression, drug resistance and metastatic spread. Although several biomarkers are implicated in these processes, their distribution within the ovary and association with single cell type has neither been established nor demonstrated across ovarian tumor developmental stages...

Endothelial-to-mesenchymal transition (EndMT), which is characterized by increased proliferation, migration and invasion of endothelial cells, increased expression of mesenchymal markers and reduced expression of endothelial markers, has been reported to be closely related to the pathogenesis of several diseases, including pulmonary fibrosis. Resistin-like molecule-β (RELM-β), also known as "found in inflammatory zone 2" (FIIZ2), plays an essential role in airway remodeling and pulmonary fibrosis; however, its role and mechanism in EndMT remain unclear...
