The potential value of microRNAs as new biomarkers for pancreatic cancer (PCa) screening was explored in this study. Fecal microRNAs from stool samples obtained from 29 PCa patients, 22 chronic pancreatitis (CP) patients and 13 normal individuals were extracted, and 7 microRNAs (miR-16, miR-21, miR-155, miR-181a, miR-181b, miR-196a and miR-210) were detected. miR-181b and miR-210 discriminated ...
Developing novel strategies against human colorectal cancer (CRC) cells is needed. Activation of AMP-activated protein kinase (AMPK) could possibly inhibit CRC cells. Protein kinase C ζ (PKCζ) is an AMPK negative regulator. Here we found that PKCζ expression was significantly elevated in human colon cancer tissues and CRC cells. PKCζ upregulation was correlated with AMPK in-activation and mTOR ...
BACKGROUND The main cause of death in medulloblastoma is recurrence associated with leptomeningeal dissemination. During this process, the role of microRNAs (miRs) in the acquisition of metastatic phenotype remains poorly understood. This study aimed to identify the miR involved in leptomeningeal dissemination and to elucidate its biological functional mechanisms. MATERIALS AND METHODS We ana...
UNLABELLED Accumulating evidence demonstrates that microRNA-29 (miR-29) expression is prominently decreased in patients with hepatic fibrosis, which consequently stimulates hepatic stellate cells' (HSCs) activation. We used a cDNA microarray study to gain a more comprehensive understanding of genome-wide gene expressions by adjusting miR-29a expression in a bile duct-ligation (BDL) animal model...
5-Fluorouracil (5-FU) is a classic chemotherapeutic drug that has been widely used for colorectal cancer treatment, but colorectal cancer cells are often resistant to primary or acquired 5-FU therapy. Several studies have shown that miR-21 is significantly elevated in colorectal cancer. This suggests that this miRNA might play a role in this resistance. In this study, we investigated this possi...
B7-H3, a surface immunomodulatory glycoprotein, inhibits natural killer cells and T cells. The monoclonal antibody (mAb) 8H9 is specific for 4Ig-B7-H3, the long and principal form of B7-H3. Early results from radioimmunotherapy using 8H9 have shown promise in patients with metastatic solid tumors to the central nervous system. Whereas B7-H3 transcript was ubiquitously expressed in a wide spectr...
TGF-β (transforming growth factor-β) is well identified as a central mediator in renal fibrosis. TGF-β initiates canonical and non-canonical pathways to exert multiple biological effects. Among them, Smad signaling is recognized as a major pathway of TGF-β signaling in progressive renal fibrosis. During fibrogenesis, Smad3 is highly activated, which is associated with the down-regulation of an ...
چکیده سابقه و هدف تغییر بیان میکرو RNA می‌تواند باعث شروع و پیشرفت سرطان شود. هدف از مطالعه حاضر، بررسی میزان بیان miR-125a و ارتباط آن با JAK2 allele burden و یافته‌های آزمایشگاهی در بیماران مبتلا به نئوپلاسم‌های میلوپرولیفراتیو شامل پلی‌سیتمی ورا (PV) و ترومبوسیتمی اساسی(ET) بود. مواد و روش‌ها مطالعه حاضر از نوع تجربی بود. در مجموع 40 بیمار مبتلا به PV و ET در زمان تشخیص مورد بررسی قرار گرف...
