The recently identified class of microRNAs (miRs) provided a new insight into cancer research, since abnormalities of members of microRNAs family have been found in various types of cancer. However, the relationship between five miRNAs (miR146a, miR155, miR21, miR135a, and miR147b) and colorectal cancer remains unclear. In the present study, we examined expression of these miRNAs in 25 pair-mat...
Menin, a protein encoded by the MEN1 gene, is mutated in patients with multiple endocrine neoplasia type 1 (MEN1). Menin acts as a tumor suppressor in endocrine organs while it is also required for transformation of a subgroup of leukemia. The recently solved crystal structure of menin with different binding partners reveals that menin is a key scaffold protein that cross-talks with various par...

مقدمه: تمرینات ورزشی نقش مهمی در پیشگیری و کمک به درمان سرطان پستان ایفا می کند. هدف پژوهش حاضر بررسی اثرات کمک درمانی تمرینات ورزشی بر بیان ریز rna-155 و ژن سرکوب گر پیام رسان سایتوکاینی-1 (socs1) در تومور موش مبتلا به سرطان پستان وابسته به گیرنده استروژن بود. روش بررسی: 16 موش بالب سی ماده در 2 گروه، تومور- ورزش (et) و تومور-استراحت (rt) به طور تصادفی قرار گرفتند. پس از آشناسازی، یک میلیون سر...
Genetic redundancy poses a major problem to the analysis of gene function. RNA interference allows the down-regulation of several genes simultaneously, offering the possibility to overcome genetic redundancy, something not easily achieved with traditional genetic approaches. Previously we have used a polycistronic miR155-based framework to knockdown expression of three genes of the early B cell...
Population heterogeneity in growth trajectories can be detected with growth mixture modeling (GMM). It is common that researchers compute composite scores of repeated measures and use them as multiple indicators of growth factors (baseline performance and growth) assuming measurement invariance between latent classes. Considering that the assumption of measurement invariance does not always hol...
BACKGROUND Some variables like Socioeconomic Status (SES) cannot be directly measured, instead, so-called 'latent variables' are measured indirectly through calculating tangible items. There are different methods for measuring latent variables such as data reduction methods e.g. Principal Components Analysis (PCA) and Latent Class Analysis (LCA). OBJECTIVES The purpose of our study was to mea...
Featured Article: Yanaihara N, Caplen N, Bowman E, Seike M, Kumamoto K, Yi M, et al. Unique microRNA molecular profiles in lung cancer diagnosis and prognosis. Cancer Cell 2006;9:189 –98. Recent evidence has revealed that microRNAs (miRNAs) function as tumor suppressors and oncogenes, and therefore miRNAs might prove useful in the diagnosis and treatment of cancer. In 2002, Croce’s group report...
Introduction Tumour necrosis factor (TNF) receptor– associated periodic syndrome (TRAPS) is a hereditary autoinflammatory condition resulting from a range of mutations in the TNFRSF1A gene. It is characterised in part by recurrent episodes of inflammation, affecting connective tissues, and manifesting as migratory erysipelas, myalgia and serositis. A number of aberrant inflammatory responses ha...
