آنومالی may-hegglin یک اختلال نادر اتوزومال غالب است که با تریاد کاهش پلاکت، پلاکت های بزرگ و اجسام شبیه دوهل در گرانولوسیتها مشخص می گردد. .هدف از این بررسی گزارش اولین مورد نارسایی در ایران و تعیین نوع موتاسیون مربوطه است. در این بررسی آزمایش cbc و گستره خون محیطی دو بیمار از یک خانواده (پدر و پسر) که به ترتیب 51 و 15 ساله بودند با دو ضدانعقاد edta و سیترات تری سدیم با شمارنده خودکار و بررسی ...
MYH9-related disease ( MYH9-RD) is an autosomal dominant thrombocytopenia with giant platelets variably associated with young-adult onset of progressive sensorineural hearing loss, presenile cataract, and renal damage. MYH9-RD is caused by mutations of MYH9 , the gene encoding for non-muscle heavy-chain myosin-9. Wild-type and mutant myosin-9 aggregate as cytoplasmic inclusions in patients' leu...
The phosphorylation of the short C-terminal cytoplasmic domain of the somatic angiotensin-converting enzyme (ACE) is involved in the regulation of enzyme shedding. We determined whether the phosphorylation of the cytoplasmic domain of ACE (ACEct) on Ser1270 regulates the cleavage/secretion of the enzyme by affecting its association with other proteins. ACE was associated with beta-actin and the...
MYH9 (myosin, heavy chain 9, non-muscle) as a gene encodes NM II-A (non-muscle II-A) protein, exists primarily in the cytoplasm. MYH9 consists of 2 mysoin heavy chains with a relative molecular mass of 230 kDa. Previous studies have shown that MYH9 is involved in a number of diseases, including cancer. However, the exact role of MYH9 in colon cancer is still unclear. Therefore, we used a tissue...
INTRODUCTION Myosin-9 (MYH9) belongs to the myosin superfamily of actin-binding motor protein. Recently, MYH9 has been thought to be associated with cancer cell migration, invasion, and metastasis. The aims of this study were to immunohistochemically examine MYH9 expression in surgically resected non-small cell lung cancer (NSCLC), and evaluate its correlations with clinicopathological paramete...
MYH9 expression has previously been demonstrated as an independent predictor of clinical outcome in solid tumors. However, the prognostic relevance of MYH9 expression in acute myeloid leukemia is still unclear. Here, we found high MYH9 expressers were seen more frequently in females and more frequently in M4 morphology. We also found high MYH9 expressers had lower percentage of bone marrow blas...
Macrothrombocytopenia in MYH9-related disease (MYH9-RD) results from defects in nonmuscular myosin-IIA function. Thrombopoietin receptor agonists (eltrombopag; romiplostim) seem to improve hemostasis, but little is known about their biologic effects in MYH9-RD. We administered romiplostim to Myh9 / mice (100 g/kg, every 3 days, during 1 month). MKs increased to similar numbers in Myh9 / and wil...
Macrothrombocytopenia in MYH9-related disease (MYH9-RD) results from defects in nonmuscular myosin-IIA function. Thrombopoietin receptor agonists (eltrombopag; romiplostim) seem to improve hemostasis, but little is known about their biologic effects in MYH9-RD. We administered romiplostim to Myh9(-/-) mice (100 μg/kg, every 3 days, during 1 month). MKs increased to similar numbers in Myh9(-/-) ...
BACKGROUND MYH9-related disease (MYH9-RD) is a rare syndromic disorder deriving from mutations in MYH9, the gene for the heavy chain of non-muscle myosin IIA. Patients present with congenital thrombocytopenia and giant platelets and have a variable risk of developing sensorineural deafness, kidney damage, presenile cataract, and liver abnormalities. Almost all MYH9-RD patients develop the heari...
Nonmuscle myosin heavy chain IIA (NMMHCIIA) encoded by MYH9 is associated with autosomal dominantly inherited diseases called MYH9 disorders. MYH9 disorders are characterized by macrothrombocytopenia and very characteristic inclusion bodies in granulocytes. MYH9 disorders frequently cause nephritis, sensorineural hearing disability and cataracts. One of the most common and deleterious mutations...
