We have previously demonstrated that endothelin (ET)-1 and its subtype A receptor (ET-AR) expression are increased in lung under hypoxic conditions and that activation of ET-AR by ET-1 is a major mediator of hypoxia-induced pulmonary hypertension in the rat. The present study tested the hypothesis that the hypoxia-responsive tyrosine kinase receptor-activating growth factors fibroblast growth f...
OBJECTIVE To compare the absolute risk (AR) screening approach to the current approach of risk adjusted to maternal age in patients undergoing first-trimester screening (FTS). MATERIAL AND METHODS Three-stage retrospective analysis of 3073 pregnancies that had FTS during 2006-2007. (1) Distribution analysis of AR as defined by (final FTS risk)/(risk by age). (2) Analysis of the screen-positiv...
BACKGROUND/OBJECTIVES Chronic ultraviolet (UV) exposure-induced reactive oxygen species (ROS) are commonly involved in the pathogenesis of skin damage by activating the metalloproteinases (MMP) that break down type I collagen. Adenophora remotiflora (AR) is a perennial wild plant that inhabits Korea, China, and Japan. The present study investigated the protective effects of AR against UVB-induc...
DJ-1 was identified by us as a novel oncogene that transforms mouse NIH3T3 cells in cooperation with ras. We later identified PIAS (protein inhibitor of activated STAT)xalpha as a DJ-1-binding protein, and found that DJ-1 restored androgen receptor (AR) transcription activity that was repressed by PIASxalpha. To further characterize the function of DJ-1, we cloned cDNA encoding a novel DJ-1-bin...
Background & Objective: Our knowledge about correlation of androgen receptor expression and clinicopathological properties of triple-negative breast cancer (TNBC) patients is inadequate, particularly in the Iranian population. The main aim of the present study was to assess the AR expression in TNBC Iranian patients and evaluate its correlation with their clinicopathological pa...
PURPOSE Persistent androgen receptor (AR) transcriptional activity is clinically evident in castration-resistant prostate cancer (CRPC). Therefore, AR remains as a viable therapeutic target for CRPC. All current hormonal therapies target the C-terminus ligand-binding domain (LBD) of AR. By using EPI to target AR activation function-1 (AF-1), in the N-terminal domain that is essential for AR tra...
مدیریت بهینه عوامل محیطی به‌ویژه نور خورشید در کشت داربستی تمشک،یکی از راهکارهای افزایش میزان محصول و کیفیت آن است. به‌منظور بررسی تأثیر فاصله کاشت و تعداد شاخه رویشی بر خصوصیات فتوسنتزی و عملکرد تمشک سیاه بی‌خار، آزمایشی به‌صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با 4 تکرار، در باغ تجاری چه...
Targeting the activation function-1 (AF-1) domain located in the N-terminus of the androgen receptor (AR) is an attractive therapeutic alternative to the current approaches to inhibit AR action in prostate cancer (PCa). Here we show that the AR AF-1 is bound by the cochaperone Bag-1L. Mutations in the AR interaction domain or loss of Bag-1L abrogate AR signaling and reduce PCa growth. Clinicall...
Hepatic ischemia reperfusion (IR) injury causes acute kidney injury (AKI). However, the contribution of AKI to the pathogenesis of liver IR injury is unclear. Furthermore, controversy still exists regarding the role of A(1) adenosine receptors (A(1)ARs) in AKI. In this study, we determined whether exogenous and endogenous A(1)AR activation protects against AKI with subsequent liver protection a...
مشکل ناباروری حدود 15% تمام زوجین را شامل می شود و از این میان سهم مردان در ناباروری حدود 50% می باشد. آندروژن برای پیشرفت و ایجاد فنوتیپ مردانه قبل از تولد و اسپرماتوژنز در حین بلوغ ضروری می باشد. عملکرد آندروژنها از طریق رسپتور آندروژن، ar، هدایت می شود، از این رو، موتاسیونها و پلی مورفیسمهای ژن ar و پروتئین حاصل از آن به طور مشخصی با کاهش اسپرماتوژنز و ناباروری در مردان همراه است. در ژن کدکن...
