BACKGROUND It has been hypothesized that blastocyst integrin expression changes can affect the spontaneous miscarriage in polycystic ovarian syndromes (PCOS). OBJECTIVE In this study, the profile of integrin genes and proteins was investigated on blastocyst of the PCOS experimental mouse model. MATERIALS AND METHODS 30 NMRI female mice were equally divided into 3 groups: control, experiment...
This study determined if blocking ligand occupancy of the αVβ3 integrin could inhibit the pathophysiologic changes that occur in the early stages of diabetic nephropathy (DN). Diabetic rats were treated with either vehicle or a monoclonal antibody that binds the β3 subunit of the αVβ3 integrin. After 4 weeks of diabetes the urinary albumin to creatinine ratio (UACR) increased in both diabetic a...
Bone metastases occur in approximately 70% of metastatic breast cancer patients, often leading to skeletal injuries. Current treatments are mainly palliative and underscore the unmet clinical need for improved therapies. In this study, we provide preclinical evidence for an antimetastatic therapy based on targeting integrin β3 (β3), which is selectively induced on breast cancer cells in bone by...
BACKGROUND Cesarean scar pregnancy (CSP) is a late serious complication of cesarean section. There has been an increase in the incidence of CSP worldwide in recent years. It's a life-threatening condition because of the high risk of uncontrolled hemorrhage and uterine rupture. The mechanism of CSP is still unclear. The endometrial receptivity might be different in the cesarean scar between CSP ...
PLC-β is widely distributed in eukaryotic cells and the key enzyme phosphatidylinositol signal transduction pathway. The cellular functions regulated by its four subtypes (PLC-β1, PLC-β2, PLC-β3, PLC-β4) play an important role maintaining homeostasis of organism. related signals can promote or inhibit occurrence development cancer affecting growth, differentiation metastasis cells, while target...
Few therapeutic options exist for meniscus repair after injury. Local delivery of growth factors may stimulate repair and create a favorable environment for engineered replacement materials. In this study we assessed the effect of basic fibroblast growth factor (bFGF) (a pro-mitotic agent) and transforming growth factor β3 (TGF-β3) (a pro-matrix formation agent) on meniscus repair and the integ...
Pulmonary hypertension is a rare disorder that, without treatment, is progressive and fatal within 3-4 years. Current treatment involves a diverse group of drugs that target the pulmonary vascular bed. In addition, strategies that increase nitric oxide (NO) formation have a beneficial effect in rodents and patients. Nebivolol, a selective β1 adrenergic receptor-blocking agent reported to increa...
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a life-threatening disease in which intracranial hemorrhage (ICH) is the major risk. Although thrombocytopenia, which is caused by maternal antibodies against β3 integrin and occasionally by maternal antibodies against other platelet antigens, such as glycoprotein GPIbα, has long been assumed to be the cause of bleeding, the mechanism of...
Binding of the talin-1 FERM (4.1/ezrin/radixin/moesin) domain to the β3 cytosolic tail causes activation of the integrin αIIbβ3. The FERM domain also binds to acidic phospholipids. Although much is known about the interaction of talin-1 with integrins and lipids, the relative contribution of each interaction to integrin regulation and possible synergy between them remain to be clarified. Here, ...
AIMS To investigate the relationship between urinary bladder mucosal expression of β3-adrenoceptor (AR) mRNA and urodynamic findings in patients with lower urinary tract symptoms and benign prostatic obstruction (BPO). METHODS During surgical prostate resection of 32 BPO patients, mucosal biopsies were collected and analyzed by reverse transcriptase polymerase chain reaction to determine the ...
