سرطان معده یکی از سرطان های شایع در ایران و جهان است. در ایران، بیش از 80 درصد بیماران با سرطان معده در مرحله ای از بیماری تشخیص داده می شوند که درمان های متداول تاثیری در افزایش طول عمر بیماران ندارد و تهاجم و متاستاز در نهایت باعث مرگ بیماران می گردد؛ لذا لزوم شناخت مکانیسم های مولکولی درگیر در آغاز، پیشرفت، و به خصوص تهاجم و متاستاز تومورهای معدی جهت معرفی مارکرهای مولکولی برای تشخیص زودرس، ...

rna های غیر کدکننده ی طویل (lncrna)، گروهی از rna غیر کد کننده هستند که امروزه در مقیاس ژنومی گسترده ایی مورد مطالعه قرار گرفته اند. lncrnaها دارای نقش های بیولوژیکی متنوعی در زمینه ی بیان ژن، تمایز سلولی و بیماریزایی هستند. مطالعات اخیر بیان lncrna ها را در بسیاری از سرطان ها ازجمله بدخیمی های خونی نشان داده اند که می توانند ابزاری جهت تشخیص و پیش آگهی بسیاری از بیماری ها و به عنوان یک جایگزین...

The long non-coding RNA HOTAIR has been reported to be a poor prognostic biomarker in a variety of malignant tumors. However, little is known about the association of HOTAIR with gastric cancer. We examined the expression of HOTAIR in 68 gastric cancer samples using quantitative real-time RT-PCR and analyzed its correlation with the clinical parameters. The functional role of HOTAIR was examine...

BACKGROUND Long noncoding RNA Hox transcript antisense intergenic RNA (HOTAIR) has been characterized as a negative prognostic factor in breast and colon cancer patients. The clinical significance and function of HOTAIR in glioma remains unclear. METHODS We analyzed the clinical significance of HOTAIR in 3 different glioma cohorts with gene expression data, including correlation with tumor gr...

There is a growing perception that long non-coding RNAs (lncRNAs) modulate cellular function. In this study, we analyzed the role of the lncRNA HOTAIR in mesenchymal stem cells (MSCs) with particular focus on senescence-associated changes in gene expression and DNA-methylation (DNAm). HOTAIR binding sites were enriched at genomic regions that become hypermethylated with increasing cell culture ...

BACKGROUND Over-expression of long non-coding RNA HOTAIR has been reported in several types of cancer. Yet its involvement in gastric cancer (GC) has not been well understood. The aim of present study was to examine the expression pattern of HOTAIR in GC patients, then, explore its role in promoting cancer invasion and underlying molecular mechanism. METHODS The expression level of HOTAIR in ...

Background: Gastric cancer (GC) is the fourth most common human malignancy and the second reason for cancer morbidity worldwide. Long noncoding RNA (LncRNA) HOX transcript antisense RNA (HOTAIR) has recently emerged as a promoter of metastasis in various cancer types, including GC, through the epithelial‑mesenchymal transition (EMT) process. However, the exact mechanism of HOTAIR in promoting E...

Long noncoding RNAs (lncRNAs) have emerged recently as a new class of genes that regulate cellular processes. HOTAIR (Hox transcript antisense intergenic RNA), an approximately 2.2 kb long noncoding RNA transcribed from the HOXC locus, is upregulated in various diseases. However, the role of HOTAIR in Parkinson's disease (PD) remains unclear. A mouse model of PD was developed by intraperitoneal...

Glioblastoma multiforme (GBM) is the most common and aggressive malignant adult primary brain tumor. Despite surgical resection followed by radiotherapy and chemotherapy, the median survival rate is approximately 14 months. Although experimental therapies are in clinical trials for GBM, there is an urgent need for a peripheral GBM biomarker for measuring treatment response. As we have previousl...

BACKGROUND The aim of this study was to determine the effect on proliferation, migration, and invasion after silencing HOTAIR in ovarian cancer SKOV3 cells, and to elucidate the potential mechanism. MATERIAL/METHODS We analyzed the mRNA expression level of HOTAIR and PIK3R3 in ovarian cancer SKOV3, OVCAR3, and A2780 cell lines. We analyzed the mRNA expression level of HOTAIR and PIK3R3 in ova...
