[ 1 ] - بررسی اگزون ا ژن FRDA در بیماران با علائم بالینی فردریش آتاکسیا
زمینه و هدف: فردریش آتاکسیا یک بیماری آتوزومال مغلوب است که معمولاً با دیس آرتریا، ضعف عضله، اسپاسم در اندام‌های تحتانی، اسکولیوز، عملکرد بد مثانه، نداشتن رفلکس در اندام‌های تحتانی و از دست دادن تعادل و لرزش همراه است. تقریباً دوسوم افراد FRDA (Friedreich's Ataxia) کاردیومیوپاتی دارند و بیشتر از 30% مبتلا به دیابت شیرین هستند. افراد دارای FRDA٬ موتاسیون‌های قابل‌شناسایی در ژن FXN می...
[ 2 ] - Is Bax/Bcl-2 Ratio Considered as a Prognostic Marker with Age and Tumor Location in Colorectal Cancer?
Background: Bax and Bcl-2 are the major members of Bcl-2 family whose play a key role in tumor progression or inhibition of intrinsic apoptotic pathway triggered by mitochondrial dysfunction. Therefore, the balance between pro- and anti-apoptotic members of this family can determine the cellular fate. Methods: In this study, the relative level of mRNA expression of Bax and Bcl-2 genes was deter...
[ 3 ] - Three Novel Mutations in Iranian Patients with Tay-Sachs Disease
Background: Tay-Sachs disease (TSD), or GM2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase A (HEXA), resulting in lysosomal accumulation of GM2 ganglioside. The aim of this study was to identify the TSD-causing mutations in an Iranian population. Methods: In this study, we examined 31 patients for TSD-causing m...
[ 4 ] - Molecular and Clinical Investigation of Iranian Patients with Friedreich Ataxia
Background: Friedreich ataxia (FRDA) is an autosomal recessive disorder caused by guanine-adenine-adenine (GAA) triplet expansions in the FXN gene. Its product, frataxin, which severely reduces in FRDA patients, leads to oxidative damage in mitochondria. The purpose of this study was to evaluate the triple nucleotide repeated expansions in Iranian FRDA patients and to elucidate distinguishable ...
[ 5 ] - A Novel Mutation in the Aprataxin (APTX) Gene in an Iranian Individual Suffering Early-Onset Ataxia with Oculomotor Apraxia Type 1(AOA1) Disease
Background: Ataxia with oculomotor apraxia type 1 (AOA1) shows early onset with autosomal recessive inheritance and is caused by a mutation in the aprataxin (APTX) gene encoding for the APTX protein. Methods: In this study, a 7-year-old girl born of a first-cousin consanguineous marriage was described with early-onset progressive ataxia and AOA, with increased cholesterol concentration and decr...
[ 6 ] - Identification of a Novel Arylsulfatase B Gene Mutation in Three Unrelated Iranian Mucopolysaccharidosis Type-VI Patients with Different Phenotype Severity
Background: Mucopolysaccharidosis type-VI (MPS-VI), which is inherited as an autosomal recessive trait, results from the deficiency of N-acetylgalactosamine 4-sulfatase (arylsulfatase B) activity and the lysosomal accumulation of dermatan sulfate. In this study, ARSB mutation analysis was performed on three unrelated patients who were originally from the West Azerbaijan province of Iran. Method...
[ 7 ] - Types of glioma brain tumors and genetic alterations in signaling pathways in them
Types of glioma brain tumors and genetic alterations in signaling pathways in them Background & Objective: Glioma is a common type of primary brain tumor originating in the glial cells that surrounds and supports neurons in the brain. These tumors arise from three different types of cells that are normally found in the brain: astrocytes, oligodendrocytes, and ependymal cells, accordingly types ...
