Tumor protein 53 (TP53), a tumor suppressor gene, is a vital cellular cancer suppressor in multicellular organisms. Murine double minute-2 (MDM2) is an oncoprotein that inhibits TP53 activity. A number of studies have examined the association of TP53 and MDM2 polymorphisms with the risk of common forms of cancer, but the findings remain inconclusive. The present study aimed to evaluate the impact of the 40-bp insertion/deletion (I/D) polymorphism (rs3730485) in the MDM2 promoter region and the 16-bp I/D polymorphism (rs17878362) in TP53 on the susceptibility of prostate cancer (PCa) in a sample of the Iranian population...

Aneurysmal bone cysts (ABCs) are benign bony lesions frequently accompanied by multiple cystic lesions and aggressive bone destruction. They are relatively rare lesions, representing only 1% of bone tumors. The pathogenesis of ABCs has yet to be elucidated. In the present study, a series of 22 cases of primary and secondary ABC from patients treated in Department of Orthopedic Surgery, Kagoshima University Hospital (Kagoshima, Japan) from 2001-2015 were retrospectively analyzed. The average age at the time of diagnosis of primary ABC was 17...

Kin17 DNA and RNA binding protein (Kin17) is a highly conserved protein that participates in DNA replication, DNA repair and cell cycle progression. Recently, the tumor-promoting function of Kin17 has been demonstrated and increasingly studied. In the present study, the role of Kin17 in the invasion and metastasis of non-small cells lung cancer (NSCLC) was investigated. Elevated Kin17 mRNA and protein expression was identified in a total of 97 NSCLC and benign lung lesion tissue specimens. Kin17 overexpression was significantly correlated with high tumor grade and lymph node metastasis, indicating poor patient prognosis...

Pancreatic cancer is one of the most malignant types of tumor. It is important to elucidate the underlying molecular mechanisms of pancreatic tumorigenesis and to identify novel biomarkers as therapeutic targets of pancreatic cancer. In the present study, the protein expression levels of Wnt inhibitory factor 1 (WIF1) and receptor tyrosine kinase-like orphan receptor 2 (ROR2) were examined in a collection of pancreatic ductal carcinoma and benign pancreatic lesion tissue samples using immunohistochemistry. The positive expression rate of WIF1 protein in pancreatic ductal carcinoma was demonstrated to be significantly decreased compared with that of the paracancerous tissue, benign lesions and wild-type pancreatic tissue (P=0...

Previous studies have indicated that cancer may be promoted and/or exacerbated by inflammation and infection. The cytokines produced by activated innate immune cells that stimulate tumor growth and progression are considered as important components in this process. The interleukin (IL)-23/T helper (Th)17 axis, which exerts marked pro-inflammatory effects, has emerged as an important mediator in inflammation-associated cancer. Increasing clinical evidence indicates that Th17 may promote or inhibit tumor progression, however, the function of Th17 in the pathogenesis of benign and malignant thyroid neoplasms remains unclear...

Epilobium sp. are commonly used in traditional medicine in the treatment of early stages of benign prostatic hyperplasia and inflammation. It is suggested that a dominating constituent, oenothein B, is responsible for the extracts therapeutic effects. Several bioactivities were established for extracts and oenothein B in various in vitro models, but due to the questionable bioavailability of this dimeric macrocyclic ellagitannin, their significance in the in vivo effects remains unresolved. We have thus focused our attention on a complex comparative investigation of the in vitro and in vivo activities of phytochemically characterized Epilobium angustifolium aqueous extract and oenothein B on prostate cancer cells proliferation...

Despite their efficacy in the treatment of benign prostatic hyperplasia, the popularity of inhibitors of 5α-reductase (5ARIs) is limited by their association with adverse sexual side effects. The aim of this study was to review and meta-analyze currently available randomized clinical trials evaluating the rate of sexual side effects in men treated with 5ARIs. An extensive Medline Embase and Cochrane search was performed including the following words: 'finasteride', 'dutasteride', 'benign prostatic hyperplasia'...

Dexamethasone (Dex) is commonly used in the treatment of a variety of benign and malignant conditions. Unfortunately, although it has a variety of teratogenic effects, it remains used in clinical practice for pregnant women mainly due to limited alternatives. However, there is limited knowledge of the mechanisms that lead to the observed teratogenic effects. In this study, the effects of Dex during embryogenesis on neural crest development were evaluated in the early chick embryos. First, we demonstrated that 100µL 10-6 M Dex treatment leads to craniofacial developmental defects, and also retards embryo growth and plausibly can cause embryo demise...

Rituximab is a plausible alternative first-line treatment of ANCA-associated vasculitis. Adverse effects related to its infusion are common and usually have a benign course. However, there have been reports of refractory cardiogenic shock simulating septic shock. We report an 81-year-old male with the diagnosis of ANCA associated vasculitis. Rituximab 500 mg was administered intravenously for a relapse. The infusion proceeded without incident. However, 24 hours after its administration the patient began with fever, chills, coughing and strong malaise...

Benign intraperitoneal metastatic leiomyomatosis is a rare benign disease that is observed when a leiomyoma is present in the peritoneal surface. Women who have undergone hysterectomy for leiomyomas are most commonly affected. Patients are usually asymptomatic at presentation, being frequently an incidental finding in imaging studies. Ultrasound and CT play an important role in the diagnosis. The lesions are histologically identical to their uterine counterparts. There are different theories about the pathogenesis of the disease, including peritoneal seeding after laparoscopic hysterectomy...

Myelolipoma is a kind of rare benign tumour composed of mature adipocytes and hemopoietic elements, and is most often found in the adrenal glands. Primary mediastinal myelolipoma (PMM) more rarely happens and has no definite symptoms, and mediastinal masses are usually found in chest examination. The patients normally receive a surgical resection and have a favorable prognosis after postoperative pathological diagnosis. Here, we present the case of PMM, which was resected via video-assisted thoracic surgery (VATS), and investigate recent correlative literatures to summarize its etiology, histopathology, differential diagnosis and therapeutic method...

Cardiac rhabdomyoma, a type of benign myocardial tumor, is regarded as the most common fetal cardiac tumor. Rhabdomyomas are usually found before birth or during the first year of life. It is widely accepted that rhabdomyomas are strongly associated with tuberous sclerosis, and tend to regress spontaneously without surgical excision. However, if the tumor has caused significant obstruction or refractory arrhythmias, the surgery should be advocated. Most of the surgeries for pediatric cardiac tumors are performed under cardiopulmonary bypass (CPB) with cardioplegia...

Although lymphoepithelial cysts (LECs) of the pancreas are benign lesions, most of them have been treated with surgical resection due to diagnostic difficulty. We report a 66-year-old woman diagnosed with pancreatic LECs. Abdominal ultrasound revealed two masses in the pancreas, which were not visible on the abdominal computed tomography. In an abdominal magnetic resonance imaging, pancreas lesions showed solid tumors, which revealed a low signal intensity on T1-, moderate high signal intensity on T2 weighted images, and homogeneous delayed enhancement in the portal venous phase...
