microRNAs (miRNAs) are involved in almost all normal and pathogenic eukaryotic cell processes. One area in which the influence of miRNAs is most prominent is cancer. Numerous expression surveys and more focused studies have revealed miRNA involvement in carcinogenesis, cellular pathology, cell behavior and prognosis. Large-scale comparisons of miRNA expression in varioius types of cancer have n...
Estrogen is a known risk factor in human breast cancer. In rodent models, estradiol has been shown to induce tumors in those tissues in which this hormone is predominantly converted to the catechol metabolite 4-hydroxyestradiol by a specific 4-hydroxylase enzyme, whereas tumors fail to develop in organs in which 2-hydroxylation predominates. We have now found that microsomes prepared from human...
Identifying genetic variants with pleiotropic associations can uncover common pathways influencing multiple cancers. We took a two-stage approach to conduct genome-wide association studies for lung, ovary, breast, prostate, and colorectal cancer from the GAME-ON/GECCO Network (61,851 cases, 61,820 controls) to identify pleiotropic loci. Findings were replicated in independent association studie...
BACKGROUND Previous studies have shown the sex differences in lung cancer and the associations between estrogen-related genes and non-small cell lung cancer. In the present study, we assumed the existence of shared candidate genes that are common in lung and breast cancers, and examined whether women with a family history of breast cancer are at increased risk of lung cancer compared with men, ...
background: norepinephrine plays a trophic role in the control of cell replication and differentiation in target cells that express adrenergic receptors. methods: in this study, we have tested the influence of infraphysiological, physiological and supraphysiological concentrations (0.0001 nm, 1 nm, 10000 nm) of human norepinephrine on the proliferation of breast cancer cells (human breast adeno...
abstract background: gastric cancer is the second most common cancer and also the second cancer related death all over the world. in recent years recorded data for tumor has shown a rise in the incidence of gastric cancer in young individuals. the present study was designed to compare some of the epidemiologic characteristics of individuals suffering from gastric cancer aged below and above f...
introduction: transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. in this study, we compared and evaluated the treatment effects of dual frequency irradiatio...
Parathyroid carcinoma is a rare malignant neoplasm associated with known cancer syndromes. Hyperparathyroidism, as often observed in parathyroid carcinoma, is associated with an increased risk of developing breast cancer. A 76 year-old male patient treated with surgery and bicalutamide for parathyroid adenocarcinoma came to our observation during follow-up. 18F-FDG PET/CT showed a pathological ...
Breast cancer is the most common cancer in women. Metastatic disease involvement of the stomach is usually a manifestation of advanced disease. Isolated metastatic involvement of the stomach from a primary breast lesion is rare. These lesions can mimic primary gastric carcinoma and can be hard to distinguish due to very similar clinical, endoscopic and histological features. The authors here de...
A case of synchronous metastasis of breast cancer to the stomach and colon is reported. A 38-year-old woman with a history of bilateral breast cancer was admitted for endoscopic examination because of occult blood. Endoscopic examination showed elevated lesions on the mucosal surface of the stomach and cecum. Histopathological examination of the biopsy specimens obtained from both sites showed ...
