Sickle cell disease (SCD)-associated priapism is characterized by decreased nitric oxide (NO) signaling and downregulated phosphodiesterase (PDE)5 protein expression and activity in the penis. Priapism is also associated with testosterone deficiency, but molecular mechanisms underlying testosterone effects in the penis in SCD are not known. Given the critical role of androgens in erection physiology and NO synthase (NOS)/PDE5 expression, we hypothesized that testosterone replacement to eugonadal testosterone levels reduces priapism by reversing impaired endothelial (e)NOS activity and molecular abnormalities involving PDE5...

Oestrogen targeting in the human genital ducts is still not well-known. In fact, to date, the localization of oestrogen receptors, ESR1 and ESR2, is controversial and the presence of the membrane oestrogen receptor GPER (G protein-coupled oestrogen receptor) is unexplored. This study has investigated the expression of GPER, ESR1, ESR2 in human ductuli efferentes and proximal caput epididymis by immunohistochemistry and Western blot analysis. Furthermore, the presence of PELP1 (proline-glutamic acid-leucine-rich protein 1), a co-regulator of the oestrogen receptors, was also evaluated...

Recent progress in the understanding non-thermal plasma (NTP) properties prompted its application in the treatment of various diseases. However, therapeutic effect of NTP on keloid cells has not been reported previously. We sought to investigate the effect of NTP treatment on keloid by comparing cell migration and collagen production of keloid (KFs) and normal fibroblasts (NFs) and determined the regulatory pathways involved. We assessed NTP effects on cell migration in KFs and NFs by the wound healing assay and measured the expression of the epidermal growth factor receptor (EGFR), signal transducer and activator of transcription-3 (STAT3), and collagen by western blot...

BACKGROUND: Recently our group has described a new autosomal dominant bleeding disorder characterized by very high plasma levels of soluble thrombomodulin (TM). The THBD c.1611C>A (p.Cys537X) mutation in heterozygous state was found in the propositus. This mutation leads to the synthesis of a truncated TM which has lost the last three amino-acids of the transmembrane domain and the cytoplasmic tail. OBJECTIVE: We investigated the mechanism responsible for TM shedding in endothelial cells with THBD c...

Stromal interaction molecule 1 (STIM1), an endo/sarcoplasmic reticulum Ca2+ sensor, has been shown to control a Ca2+-dependent signal that promotes cardiac hypertrophy. However, whether STIM1 has adaptive role that helps to protect against cardiac overload stress remains unknown. We hypothesized that STIM1 deficiency causes a maladaptive response to pressure overload stress. We investigated STIM1 heterozygous KO (STIM1+/-) mice hearts, in which STIM1 protein levels decreased to 27% of wild-type (WT) with no compensatory increase in STIM2...

Compelling evidence has demonstrated that the M1 macrophage phenotype is central to atherosclerotic lesion development. SIRT2, an NAD(+)-dependent sirtuin deacetylase, is involved in modulating macrophage polarization. However, the role of SIRT2 in atherosclerotic progression remains unknown. Female LDL receptor knockout (LDLr(-/-)) mice were randomly divided into four groups for treatment with saline, empty lentivirus, lentivirus-SIRT2, or shRNA-SIRT2 for 4 weeks. Thereafter, the mice were fed an atherogenic high-fat diet (HFD) for another 8 weeks...

Obstructive sleep apnea hypopnea syndrome (OSAHS) is associated with glucose intolerance, insulin resistance and type 2 diabetes mellitus (T2DM). Although several studies have revealed that intermittent hypoxia (IH) in OSAHS may further aggravate pancreatic β cell damage and promote the evolution of type 2 diabetes (T2DM) by increasing oxidative stress, the underlying mechanisms are unclear. Honokiol, a potent radical scavenger, has been demonstrated to ameliorate oxidative stress in many cases. The present study aimed to explore the potential mechanism of IH and diabetes synergistically damage and destruct the pancreatic β cell, examine the effects of honokiol on ameliorating pancreatic β cell injury in this context and explore the mechanism of such effects...

OBJECTIVE: Status epilepticus (SE) is a common, life-threatening neurological emergency that confers a high degree of morbidity and mortality. Increasing evidence indicates that neuroinflammation plays a critical role in the pathogenesis of SE. MicroRNA-146a (miR-146a) has been reported to be an important posttranscriptional inflammation-associated microRNA. The aim of this study was to investigate the effect of miR-146a in SE and the mechanism by which it operates. METHODS: To study the effect of miR-146a in SE, we chose intracerebroventricular injection for rat at 21-28days old, and made a lithium-pilocarpine-induced SE rat model...

BACKGROUND: Ferroptosis is a recently discovered form of iron-dependent nonapoptotic cell death. It is characterized by loss of the activity of the lipid repair enzyme, glutathione peroxidase 4 (GPX4), and accumulation of lethal reactive lipid oxygen species. However, we still know relatively little about ferroptosis and its molecular mechanism in gastric cancer (GC) cells. Here, we demonstrate that erastin, a classic inducer of ferroptosis, induces this form of cell death in GC cells and that cysteine dioxygenase 1 (CDO1) plays an important role in this process...

There were 134,000 new diagnosis and 49,000 deaths in 2016 due to colorectal cancer. Similar to most cancers, early diagnosis increases the chance of successful treatment. Detection of tumor-associated antigens or the immune response against such markers is one of the most common methods of diagnosis. In that regard, we aimed to design and express a chimeric protein from the most common tumor-associated antigens in colorectal cancer and assess its ability to detect the immune response in comparison with the parental tumor-associated antigens in patient's sera...
