Semaphorin 3A deficiency improves hypoxia-induced myocardial injury via resisting inflammation and cardiomyocytes apoptosis.
In this study, decline in Sema 3A was discovered in hypoxia-treated myocardial cells. When this decline was enhanced by silencing of Sema 3A gene, hypoxia-induced myocardial cell injury could be partially improved. Sema 3A deficiency can resist hypoxia-induced inflammatory factors (TNF-α, IL-1β and IL-6) secretion, cell viability decline, cardiomyocyte apoptosis, ROS release, ATP generation decline as well as GSH/GSSG ratio decline in H9C2 cells. Besides, hypoxia-induced bcl-2 decrease and cleaved caspase-3 increase also can be partially reversed during Sema 3A deficiency. All these findings reflect that reduced...

Owing to critical role of CCL2 during metastasis, particularly in its capacity to act as a chemoattractant for macrophages and their precursors i.e monocytes, we decided to expl...

Protective effect of Honokiol against endometriosis in Rats via attenuating Survivin and Bcl-2: A mechanistic study.
Authors: Wang Y, Jiang LL, Wu JF, Liu Z Abstract Nearly 10-15% of women in the reproductive age were affected by endometriosis and currently facing the unmet need of effective therapeutic interventions for its management. Concerning this, the present study was intended to investigate the effect of Honokiol (HK) for the treatment of endometrial hyperplasia. The rat endometrial model was established and subsequently administered with a numerous dose of HK. The histopathology of tissues was also investigated. Results showed that, HK effectively inhibit the proliferation of rat edometeriotic tissues in a dose dependent...

Association between Helicobacter pylori hopQI genotypes and human gastric cancer risk.
Authors: Kazemi E, Kahrizi D, Moradi MT, Sohrabi M, Amini S, Mousavi SA, Yari K Abstract The Helicobacter pylori use a number of mechanisms to survive in the stomach lumen and can lead to gastritis and reduction in stomach acid secretion. It has been found that the risk of developing gastric carcinoma is associated to heterogeneity of H. pylori virulence factors such as HopQ. The HopQ is one of the outer membrane proteins involved in bacterial adherence to gastric mucosa and has been suggested to also main role in the virulence of H. pylori. The purpose of the current study was to investigate the association betwee...

YiQi ChuTan Recipe Inhibits Epithelial Mesenchymal Transition of A549 Cells under Hypoxia.
This study aims to investigate mechanism of YiQi ChuTan Recipe (YCR) for inhibiting epithelial mesenchymal transition (EMT) of A549 cells under hypoxia. Flow cytometry was used to optimize YCR dosage by measuring A549 apoptosis, which were subjected to different treatments, including normal condition, hypoxia, hypoxia+YCR. Cell morphology and expression of EMT were measured with differential interference contrast microscopy, real-time PCR and western blot. Optimized condition of 4 mg/ml YCR and 2% O2 for 72 h was used to establish hypoxia. Under hypoxic condition, morphology of A549 cells changed from oblate fusi-form to e...

DNA Methylation and microRNA patterns are in association with the expression of BRCA1 in ovarian cancer.
Authors: Shariati-Kohbanani M, Zare-Bidaki M, Taghavi MM, Taghipour Z, Shabanizadeh A, Kennedy D, Dahim H, Salahshoor MR, Jalili C, Kazemi Arababadi M Abstract Ovarian cancer is the sixth most prevalent cancer in women and is considered the most lethal gynecological malignancy. It can be inherited as a familial disease but also has a strong spontaneous occurrence. Although the disease is associated with genome instability brought on by genetics and environmental factors there is evidence that mutations in the gene encoding for the breast cancer type 1 susceptibility protein (BRCA1) or its down-regulation are involv...

Angiotensin II up-regulates monocarboxylate transporters expression in the rat adrenal gland.
Authors: Kirat D, Shousha S Abstract Angiotensin II (Ang II) is a major regulator of aldosterone secretion in the adrenal zona glomerulosa because it up-regulates the expression of a large number of genes involved in aldosterone biosynthesis. The transport of acetate across adrenocortical cells is a crucial step in the de novo synthesis of cholesterol, the steroid precursor of aldosterone. However, whether Ang II can affect this transport remains unknown. The current study aims to investigate the effect of in vivo infusion of Ang II on monocarboxylate transporters (MCT1, MCT2, and MCT4) gene expression in the rat a...

Losartan sensitizes selectively prostate cancer cell to ionizing radiation.
In this study, we investigated the radiosensitizing effect of losartan on cellular toxicity induced by ionizing radiation on prostate cancer and non-malignant fibroblast cells. Human prostate cancer (DU-145) and human non-malignant fibroblast cells (HFFF2) were treated with losartan at different concentrations (0.5, 1, 10, 50 and 100 µM) and then these cells were exposed to ionizing radiation. The cell proliferation was determined using MTT assay. Our results showed that losartan exhibited antitumor effect on prostate cancer cells; it was reduced cell survival to 66% at concentration 1 µM. Losartan showed an ad...

The E-selectin S149R polymorphisms in breast cancer in a northern Iran population.
This study was performed to evaluate the association of E-selectin S149R polymorphisms and the risk of breast cancer. A total of 100 patients with breast cancer and 120 healthy sample donors (controls) were recruited in this study. Genomic DNA was extracted from fresh blood samples and genotyping of the E-selectin genes was performed using PCR-restriction fragment length polymorphism (PCR-RFLP). The frequencies of the CC, AC and AA genotypes were 2%, 84%, and 14% in patients and 2%, 12%, and 86 % in controls, respectively, while the A and C allelic frequency was 56%, 44% in patients and 92%, 8% in controls, respectively. S...

Cell-based evaluation of a novel Dictyophora indusiata polysaccharide against oxidative-induced erythrocyte hemolysis.
Authors: Liao W, Chen L, Yu B, Lei Z, Wu X, Yang J, Ren J Abstract The protective effectof a polysaccharide from Dictyophora indusiata(DP1)against oxidative hemolysis was comprehensively evaluated. The 2, 2-azobis (2-amidino-propane) dihydrochloride (AAPH)-induced erythrocyte hemolysis assay showed that DP1 exhibited excellent anti-hemolytic activity(87.4% hemolysis suppression ratio at 20 nmol/mL). Also, the formation of conjugated diene induced by cupric chloride (CuCl2) in plasma was significantly inhibited by DP1. Besides, DP1 could effectively inhibit AAPH-induced overproduction of reactive oxygen species (81....

Signaling lansdscape of prostate cancer.
Authors: Lin X, Aslam A, Attar R, Yaylim I, Qureshi MZ, Hasnain S, Qadir MI, Farooqi AA Abstract Research over the decades has gradually and sequentially shown that both intratumor heterogeneity and multifocality make prostate cancer difficult to target. Different challenges associated with generation of risk-stratification tools that correlate genomic landscape with clinical outcomes severely influence clinical efficacy of therapeutic strategies. Androgen receptor mediated signaling has gained great appreciation and rewiring of AR induced signaling cascade in absence of androgen, structural variants of AR have pro...
