Identifying the molecular basis for genotype-phenotype correlations in human diseases has direct implications for understanding the disease process and hence for the identification of potential therapeutic targets. To this end, we performed microarray expression analysis on benign (pheochromocytomas) and malignant (medullary thyroid carcinomas, MTCs) tumors from patients with multiple endocrine...
The novel polysaccharide SeGLP-2B-1 isolated from Se-enriched Ganoderma lucidum, showed anti-proliferative activity towards several cancer cell lines in vitro. To investigate the antitumor mechanisms, the apoptotic effects of SeGLP-2B-1 in human breast cancer cells were studied, and the mechanism of this action was further elucidated. Cell apoptosis was detected by Annexin V/PI staining. Caspas...
BACKGROUND Identification of factors regulating myocardial structure and function is important to understand the pathogenesis of heart disease. Because little is known about the molecular mechanism of cardiac functions triggered by serotonin, the link between downstream signaling circuitry of its receptors and the heart physiology is of widespread interest. None of the serotonin receptor (5-HT(...
بررسی بیان ژن های مربوط به زیر گروه های a۲aو a۲bگیرنده های آدنوزین در نمونه ی بافت سرطان پستان انسان
مقدمه: آدنوزین از طریق چهار زیر گروه مختلف گیرنده ی آدنوزین (a 1 ، a 2a ، a 2b و a 3 ) نقش مهمی در تنظیم رشد، تکثیر و مرگ سلول های طبیعی و سرطانی دارد. دانستن الگوی بیان زیر گروه های مختلف گیرنده های آدنوزین در بافت توموری و تفاوت آن با بافت طبیعی برای گسترش اهداف درمانی جهت کنترل مؤثرتر رشد تومور ضروری می باشد. روش ها: نمونههای جمع آوری شده شامل 11 نمونه ی سرطانی و 4 نمونه ی طبیعی بود که طبیع...
The widely spread Streptococcus agalactiae (also known as Group B Streptococcus, GBS) "hypervirulent" ST17 clone is strongly associated with neonatal meningitis. The PI-2b locus is mainly found in ST17 strains but is also present in a few non ST17 human isolates such as the ST-7 prototype strain A909. Here, we analysed the expression of the PI-2b pilus in the ST17 strain BM110 as compared to th...
Bone metastasis is commonly found in prostate cancer (PC) patients. Although the mechanisms for the recurrence of bone metastasis-derived PC during medical or surgical castration therapy are still unclear because of the lack of suitable experimental models, one hypothesis is that enhanced androgen receptor (AR) signaling causes androgen-refractory PC growth. To test this hypothesis, we first es...
Analysis of genetic interactions in the F2 of an intercross of (C57BL/6 x DBA/2) F1J revealed influences of genetic factors on life span. Females lived longer than males. Dilute brown females died sooner than females of other colors. H-2b/H-2b males died sooner than H-2b/H-2d or H-2d/H-2d males, except that among dilute brown males those of typeH-2b/H-2d died sooner. Cluster analysis suggested ...
