The suppressor of zest 12 (SUZ12), one of the core polycomb repressive complex 2 (PRC2) components, has increasingly appreciated as a key mediator during human tumorigenesis. However, its expression pattern and oncogenic roles in head and neck squamous cell carcinoma (HNSCC) remain largely unexplored yet. Here, we sought to determine its expression pattern, clinicopathological significance and biological roles in HNSCC. Through data mining and interrogation from multiple publicly available databases, our bioinformatics analyses revealed that SUZ12 mRNA was significantly overexpressed in multiple HNSCC patient cohorts...

Recent evidences suggest that hypogonadism is an important risk factor for lower urinary tract symptoms and benign prostatic hyperplasia. Several papers have discussed the role of chronic inflammation in the development of BPH, which may be modulated by the hypogonadal state. Soluble urokinase-type plasminogen activator receptor (suPAR), known protein marker of systemic inflammation, can be assayed in the seminal plasma and represents a reliable and sensitive marker of inflammation for the male accessory gland inflammation (MAGI)...

OBJECTIVE: Pituicytomas and granular cell tumours (GCTs) of the neurohypophysis are considered non-adenomatous neoplasms in the sellar region. The association between hormone hypersecretion and the tumours is seldom discussed and unclear. Therefore, we attempt to investigate this association based on our experience and a review of the literature. METHODS: We report three patients who presented with Cushing's syndrome- or acromegaly-like symptoms at our institution...

Expanded polytetrafluoroethylene (ePTFE) prosthetic valves have been widely used in clinical applications in Asian countries. However, these valves still have limits with regard to thrombosis, neointimal hyperplasia, restenosis, and valvar vegetation. The achievement of in situ endothelialization on implant materials is a promising way to overcome those limits. Here, heparin/collagen multilayers were fabricated on ePTFE films via a layer-by-layer (LBL) self-assembly technique, and then, the endothelial cell (EC) adhesive peptide sequence Arg-Glu-Asp-Val (REDV) was immobilized on the multilayers...

Benign prostatic hyperplasia (BPH) is an enlargement of the prostate gland that is frequently found in aging men. Androgens are essential for the development and differentiated function of the prostate, as well as for proliferation and survival of prostatic cells. In man, dog and rodent, there are age-related decreases in serum testosterone. Despite the lower serum testosterone levels, benign prostatic hyperplasia increases with age in men and dogs, while age-dependent prostatic hyperplasia develops in the dorsal and lateral lobes of the rat prostate...

Molar apical elongation (MAE) was the leading cause for euthanasia or death in a captive breeding colony of endangered Amargosa voles ( Microtus californicus scirpensis). Clinical signs included ocular discharge, abnormal mastication, dyspnea, abnormal mentation, weight loss, and death. Although the severity varied, all molars in all quadrants were affected. When severe, the overgrown molar reserve crown and apex protruded into the nasal meatuses, the orbit, the calvarial vault and through the ventral margin of the mandible...

To optimize the histologic evaluation of hypophysectomy specimens, sections of 207 canine pituitary glands (196 postmortem, 11 hypophysectomy specimens) were reviewed. Adenohypophyseal proliferation was the most common (n = 79) lesion. Proliferative lesions were sparsely to densely granulated; the granules were usually basophilic to chromophobic and periodic acid-Schiff-positive. Adenohypophyseal proliferation was classified as hyperplasia (n = 40) if ≤2 mm diameter with intact reticulin network, as microadenoma (n = 22) for 1-5 mm homogeneous nodules with lost reticulin network, or as macroadenoma (n = 17) for larger tumors...

Growing evidence indicates that the Toll-like receptor7/8(TLR7/8) agonist resiquimod (R848) is a potential inhibitor of type-2 immunity. However, the mechanisms mediating its therapeutic effects are not fully understood. This study investigated the effects of R848 on OVA-induced allergic rhinitis(AR) mice and the expression of IL-25, IL-33, TSLP, T-cell immunoglobulin mucin1 (TIM1) and T-cell immunoglobulin mucin3 (TIM3). BALB/c mice were intranasally sensitized and challenged with ovalbumin (OVA), and R848 was intraperitoneally injected into AR mice...

Choroid plexus hyperplasia leading to communicating hydrocephalus is a rare disorder with only 24 patients reported so far in the literature. Furthermore, genetic information is only available for six of these cases: In one patient the condition was associated with trisomy 9p, in one patient with trisomy 9 mosaicism and in three patients with tetrasomy 9p. Here, we describe four additional patients with choroid plexus hyperplasia leading to various levels of hydrocephalus, and gain of the entire chromosome 9p region: Three with trisomy 9p and one with tetrasomy 9p...

Aberrant levels of preadipocyte differentiation, triggered by adipocyte hyperplasia and hypertrophy, results in the obesogenic phenotype. Obesity is a risk factor for several metabolic disorders. In this paper, dehydroleucodine inhibited the accumulation of lipid droplets and decreased the elevations of triglycerides, and this inhibitory effect occurred during the early stage of adipogenesis. Thus, not only did dehydroleucodine downregulate the expression of C/EBPα and PPARγ, it also strongly blocked the expression of C/EBPβ, an early stage biomarker of early adipogenesis, in a concentration-dependent manner...

Prostate cancer (PCa) is the most commonly diagnosed malignancy in men and the second leading cause of cancer-related death in industrialized countries. Epidemiologic evidence suggests that obesity promotes aggressive PCa. Recently, a family of Free Fatty Acid (FFA) receptors (FFARs) has been identified and reported to affect several crucial biological functions of tumor cells such as proliferation, invasiveness, and apoptosis. Here we report that oleic acid (OA), one of the most prevalent FFA in human plasma, increases proliferation of highly malignant PC3 and DU-145 PCa cells...

We report a rare case of extensive esophageal squamous papillomas (ESPs) involving the entire esophagus and florid cardiac gland hyperplasia involving only the lower esophagus in a 39-year-old woman with heartburn and epigastric distress for the past 2 years. Previous esophagogastroduodenoscopy showed multiple ESPs involving the entire esophagus extending 38 cm from the esophageal orifice to the esophagogastric junction (EGJ). Additionally, prominent cardiac gland hyperplasia over the esophageal posterior wall was exhibited extending 12 cm from the mid-esophagus to the EGJ...

Pulmonary nodular lymphoid hyperplasia is a reactive lymphoproliferative disease. It is very rare, which means that many aspects of the disease are unknown or have not been proven. Pulmonary nodular lymphoid hyperplasia can be symptomatic or asymptomatic, progressive or not, and solitary or multiple, and a surgical approach is the current treatment of choice. We present a case of pulmonary nodular lymphoid hyperplasia that was visualized as multiple ground glass opacities on a computed tomography (CT) scan, and observed for 1 year because the patient was pregnant...

Herein, we elucidated the molecular mechanisms and therapeutic potential of glutathione peroxidase 2 (GPX2) in bladder cancer. GPX2 expression gradually increased during progression from normal to papillary or nodular hyperplasia (PNHP) and urothelial carcinoma (UC) in a rat N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN)-induced bladder carcinogenesis model. GPX2 overexpression was more marked in UC with squamous differentiation (SqD) than in pure UC. Clinical intraepithelial lesions of papillary UC and invasive UC with SqD also had strong GPX2 expression in human radical cystectomy specimens...

Coronary stent implantation has significantly improved percutaneous coronary intervention and enabled the management of early complications of plain balloon angioplasty. However, a new complication has accompanied these improvements: in-stent restenosis (ISR) arising from neointimal hyperplasia. ISR after coronary angioplasty is currently one of the main limitations of this method, leading to the recurrence of exertional angina pectoris or acute coronary syndromes. The clinical incidence of ISR after bare-metal stent (BMS) implantation is approximately 20%-35%...

Proliferating cells, compared with quiescent cells, are more dependent on glucose for their growth. Although glucose transport in keratinocytes is mediated largely by the Glut1 facilitative transporter, we found that keratinocyte-specific ablation of Glut1 did not compromise mouse skin development and homeostasis. Ex vivo metabolic profiling revealed altered sphingolipid, hexose, amino acid, and nucleotide metabolism in Glut1-deficient keratinocytes, thus suggesting metabolic adaptation. However, cultured Glut1-deficient keratinocytes displayed metabolic and oxidative stress and impaired proliferation...

We tested the hypothesis that oral NaHCO3 intake stimulates splenic anti-inflammatory pathways. Following oral NaHCO3 loading, macrophage polarization was shifted from predominantly M1 (inflammatory) to M2 (regulatory) phenotypes, and FOXP3+ CD4+ T-lymphocytes increased in the spleen, blood, and kidneys of rats. Similar anti-inflammatory changes in macrophage polarization were observed in the blood of human subjects following NaHCO3 ingestion. Surprisingly, we found that gentle manipulation to visualize the spleen at midline during surgical laparotomy (sham splenectomy) was sufficient to abolish the response in rats and resulted in hypertrophy/hyperplasia of the capsular mesothelial cells...
