[ 1 ] - Linc-ROR and its spliced variants 2 and 4 are significantly up-regulated in esophageal squamous cell carcinoma

Objective(s): Similar characteristics of molecular pathways between cellular reprogramming events and tumorigenesis have been accentuated in recent years. Reprogramming-related transcription factors, also known as Yamanaka factors (OCT4, SOX2, KLF4, and c-MYC), are also well-known oncogenes promoting cancer initiation, progression, and cellular transformation into cancer stem cells. Long non-co...

[ 2 ] - Loss of heterozygosity and microsatellite instability as predictive markers among Iranian esophageal cancer patients

Objective(s): Variation in microsatellite sequences that are dispersed in the genome has been linked to a deficiency in cellular mismatch repair system and defects in several genes of this system are involved in carcinogenesis. Our aim in this study was to illustrate microsatellite DNA alteration in esophageal cancer. Materials and Methods: DNA was extracted from formalin fixed paraffin embedde...

[ 3 ] - Expression analysis of CD44 isoforms S and V3, in patients with esophageal squamous cell carcinoma

Objective(s):  CD44 is a member of the cell adhesion molecules family. Naturally, CD44S, along with CD44V3 influence the cell motility, migration, and adhesion, while in tumor cells they lead to tumor invasion, progression, and metastasis. The purpose of this research is to evaluate the CD44S and CD44V3 expression in Esophageal Squamous Cell Carcinoma (ESCC) and to reveal their correlations wit...

[ 4 ] - Role of Brg1 in progression of esophageal squamous cell carcinoma

Objective(s): Epigenetic regulation of gene expression can be carried out through chromatin remodeling enzymes such as SWI/SNF. Brg1 also known as SMARCA4 is a catalytic subunit of SWI/SNF, which is necessary for MMPs expression. Matrix metalloproteinases (MMPs) are known as important player enzymes during tumor progression and metastasis. Aberrant epigenetic modification of chromatin should be...

[ 5 ] - تعیین ناقلین هموفیلی A در خراسان جنوبی با استفاده از سه مارکر پلی مورفیسمBclI، HindIII وAlwNI

  چکید ه   سابقه و هدف   هموفیلـی A شایع‌تریـن اختـلال انعقادی وابسته به X است. میزان شیوع این بیماری در جوامع مختلف حدود 1 تا 2 در هر 10000 نوزاد پسر می‌باشد. شیوع این بیماری در خراسان جنوبی بسیار بالاست که علت آن را شاید بتوان ایزوله بودن جمعیت آن و وجود ازدواج‌های فامیلی بسیار زیاد در این منطقه دانست. این مطالعه جهت تعیین ناقلین هموفیلی A در دو روستای کوشکک و توتکری و راه‌اندازی روش تشخیص پی...

[ 6 ] - Rapid DNA Extraction Protocol from Stool, Suitable for Molecular Genetic Diagnosis of Colon Cancer

Colorectal cancer (CRC) is one of the most common forms of cancers in the world and is curable if diagnosed at the early stage. Analysis of DNA extracted from stool specimens is a recent advantage to cancer diagnostics. Many protocols have been recommended for DNA extraction from stool, and almost allof them are difficult and time consuming, dealing with high amount of toxic materials like phen...
