بیماری آلزایمر مهمترین شکل زوال عقل در افراد مسن است که تاثیر متقابل ژن ها و محیط در شکل گیری آن نقش دارد. نقش جهش های میتوکندریایی در بیماری های مختلف فساد عصبی اثبات شده که برخی از این جهش ها به ظن قوی سبب بیماری آلزایمر در الگوی وراثت مادری آن هستند که به صورت غیر مندلی به ارث می رسد. همه ژن های trna میتوکندریایی در 24 بیمار و 50 نمونه سالم به عنوان کنترل با روش توالی یابی مورد آزمایش قرار گ...
Background and Objectives: Tumor-infiltrating regulatory T (TI-Treg) cells perform the significant function in cancer immune escape. In this study, the third generation CAR construct was designed against human CD25 antigen, the significant cell surface biomarker of TI-Tregs. Methods: Initially, the construct of anti-CD25 CAR was designed. Using RNAfold web server, the RNA secondary structure wa...
The short genes encoding transfer RNA (tRNA) molecules are highly conserved in both sequence and structure, reflecting the central role of tRNA in protein biosynthesis. The frequent occurrence of fragmented intron-containing tRNAs that require processing to form contiguous molecules is therefore surprising. Recent discoveries of permuted and split tRNA genes have added to the apparent creativit...
1. Transferase I of rat liver binds aminoacyl-tRNA to form a relatively stable complex, which is retained on cellulose nitrate filters. This reaction proceeds at both 0 degrees C and 37 degrees C and is inhibited by GTP. The resulting product is stabilized by GTP and Mg(2+). 2. Only very low quantities of deacylated tRNA are bound by transferase I. 3. Methods are described for the preparative i...
The crystal structure of the bacterial 70S ribosome refined to 2.8 angstrom resolution reveals atomic details of its interactions with messenger RNA (mRNA) and transfer RNA (tRNA). A metal ion stabilizes a kink in the mRNA that demarcates the boundary between A and P sites, which is potentially important to prevent slippage of mRNA. Metal ions also stabilize the intersubunit interface. The inte...
