[ 1 ] - Variations in Intraplatelet Phospho-VASP Expression Due to Pre-analytical Sample Preparations, Illustration of a Quality Control Issue in Platelet Pharmacology

Intraplatelet phospho-VASP analysis is a commonly used approach for monitoring of anti-platelet therapy; however, testing of intraplatelet phospho-VASP expression needs a high level of experience and proficiency. The ability to recognize how the pre-analytical variations can change the results would be helpful for the interpretation of data from intraplatelet P-VASP analysis. The aim of this st...

چکیده سابقه و هدف لوسمی لنفوبلاستیک حاد(ALL)، شایع‌ترین بدخیمی در کودکان است. به دلیل اثرات جانبی فراوان داروهای شیمی‌درمانی، استفاده از ترکیبات طبیعی مورد توجه قرار گرفته است. اُرس یک گیاه دارویی است که اثر مهاری عصاره آن بر روی چندین رده سلولی سرطانی گزارش شده است. هدف از این مطالعه، بررسی اثر کشندگی و آپوپتوتیک عصاره بخش‌های هوایی گیاه اُرس بر رده‌های سلولی ALL ( Nalm-6 و Reh) بود. مواد و رو...

[ 5 ] - تأثیر سایتوتوکسیک سه گونه گیاهی جنس گل گندم (Centaurea) بر رده سلولی لوسمی لنفوبلاستیک حاد (Nalm-6)

مقدمه: امروزه گیاهان دارویی به سبب محتوای زیست فعال و سمیت انسانی محدود به عنوان منبع ایده‌آل برای پیشگیری یا درمان سرطان مورد توجه قرار گرفته‌اند. گیاهان جنس Centaurea که تأثیر سایتوتوکسیک آنها بر چندین رده سلولی سرطانی در مطالعات پیشین نشان داده شده است، دسته‌ای از این گیاهان محسوب می‌شوند. هدف: در این مطالعه، تأثیر سایتوتوکسیک سه گونه Centaurea (C. albonitens، C. pseudoscabiosa و C. salicifo...

[ 6 ] - Investigating the inhibitory effect of miR-34a, miR-449a, miR-1827, and miR-106b on target genes including NOTCH1, c-Myc, and CCND1 in human T cell acute lymphoblastic leukemia clinical samples and cell line

Objective(s): microRNAs are small non-coding molecules that regulate gene expression in various biological processes. T-cell acute lymphoblastic leukemia (T-ALL) is a malignancy accompanied with genetic aberrations and accounts for 20% of children’s and adult’s ALL. Notch signaling pathway dysregulation occurs in 60% of T-ALL cases. In the present study, we aimed to de...

[ 7 ] - CDK Blockade Using AT7519 Suppresses Acute Myeloid Leukemia Cell Survival through the Inhibition of Autophagy and Intensifies the Anti-leukemic Effect of Arsenic Trioxide

The strong storyline behind the critical role of cyclin-dependent kinase (CDK) inhibitor proteinsin natural defense against malignant transformation not only represents a heroic perspective forthese proteins, but also provides a bright future for the application of small molecule inhibitorsof CDKs in the novel cancer treatment strategies. The results of the present study revea...

[ 8 ] - Proteasome Inhibition by Carfilzomib Induced Apotosis and Autophagy in a T-cell Acute Lymphoblastic Leukemia Cell Line

T-cell acute lymphoblastic leukemia is an aggressive hematologic malignancy which is usuallyassociated with unfavorable prognosis particularly in patients with refractory/relapsed disease.Therefore, development of novel therapeutic strategies is highly required for improving theoutcome of these patients. Although there are several studies evaluating the efficacy of proteasome<...
