One of the mechanisms for development autoimmune diseases is changes in epigenetic regulation, root causes which have not yet been established. At same time, data on role transposons as sources long noncoding ribonucleic acids (RNA) and microRNAs involved immune pathology accumulated. In evolution, transposable elements become basis emergence V(D)J recombination regulation HLA genes. Pathologic...
Breast cancer is a leading cause of related death among women worldwide and it complex disease characterized by its heterogeneity. The heterogenous characteristic the breast responsible for aggressiveness treatment resistance. stem cells (BCSCs) are population with increased propensity proliferation, differentiation, migration, invasion mammosphere formation resistance to treatment. They have a...
Objective(s): MicroRNAs (miRs) are a class of small non-coding RNAs which are associated with tumor growth and progression. In the present study, we assessed the expression of selected miRs in malignant, benign, and adjacent normal breast tissues. Materials and Methods: The expression of miR-1297, miR-3191-5P, miR-4435, and miR-4465 were...
Objective(s): MicroRNAs (miRNAs) are considered as powerful, post-transcriptional regulators of gene expression in hepatocellular carcinoma cells (HCC). However, the function of miR-92a is still unclear in HCC. Materials and Methods: Expression of miR-92a in human HCC cell lines was evaluated using qRT-PCR. MTT assay and transwell assay were used to examine the function of miR-92a in HepG2 and ...
زمینه و هدف: سرطان پستان، شایع‌ترین سرطان در میان زنان است. miRNA ها دسته‌ای از RNA های غیر کدکننده هستند که نقش مهمی در کنترل بیان ژن در سطح پس از رونویسی ایفا می‌کنند. miR-126 یک miRNA اینترونی است که در ژن EGFL7 قرار دارد. miR-126 در سرطان سینه به‌عنوان سرکوب‌کننده‌ی تومور بوده و میزان بیان آن کاهش می‌یابد. هدف این مطالعه بررسی میزان بیان miR-126 در بافت توموری و نرمال سرطان سینه و ارتباط آن...
objective: mir-302-367 is a cluster of polycistronic micrornas that are exclusively expressed in embryonic stem (es) cells. the mir-302-367 promoter is functional during embryonic development but is turned off in later stages. motivated by the cancer stem cell hypothesis, we explored the potential expression of mir-302 in brain tumor cell lines. materials and methods: in the present experimenta...
MicroRNAs are small, non-coding sequences that regulate gene expression by inducing degradation or translational inhibition of target mRNAs. These molecules control many intracellular physiological and pathological processes.Abnormal expression of these moleculs has been described in different cancers including hematopoietic cancers. According to the type of cancer and the stage, miRNA’s expres...
Abstract Circulating microRNA (miRNA), a non-coding RNA molecule, is the potential biomarker for bone and mineral metabolism. Primary hyperparathyroidism (PHPT) one of leading causes secondary osteoporosis. After parathyroidectomy, BMD improves as parathyroid hormone (PTH) decreases in patients with PHPT but degree recovery vary greatly among patients. Biomarkers which are able to predict posto...
Abstract Background and Objectives Hepatitis C virus is the main cause of hepatitis C infection that usually has no symptoms at early stages. Studies have shown changes in the expression level of microRNAs in various diseases such as hepatitis. MiR-199a and miR-196b have an inhibitory effect on hepatitis C virus. In a recent study, we examined the expression levels of miR-199a and miR-196b in ...
چکید ه سابقه و هدف میکرو rna ها، نوعی از rna های کوچک غیر کدکننده هستند و اخیراً مشخص شده که نقشی اساسی در فرآیندهای مهم سلولی از جمله تکامل و تمایز از طریق تنظیم پس از رونویسی، ایفا می کنند. میزان بیان میکرو rna ها در ارتباط با بیماری زایی بعضی بدخیمی های خونی از جمله لوسمی میلوئیدی حاد شناخته شده است . هدف از این مطالعه، بررسی بیان mir-150 و mir-155 در بیماری لوسمی میلوژنوس مزمن( cml ) بود...
