This study aimed to explore the exact mechanism of the effect of a furin inhibitor on the migration and invasion of MG-63 and Saos-2 osteosarcoma cells. MG-63 and Saos-2 osteosarcoma cells were treated with regular culture medium in the presence or absence of 480 nM α1-antitrypsin Portland (α1-PDX). Wound-healing and Transwell assays were used for the detection of the effects of α1-PDX on MG-63...
furin is a ca 2+ -dependent serine protease which cleaves proprotein substrates at the arg-xaa-(lys/arg)-arg site to generate biologically active proteins. furin’s critical role in many cellular events associated with health disorders such as hiv, sars, anthrax, and influenza as well as cancer has made inhibitors of this enzyme as therapeutic targets. to this date, the most potent inhibitor ...

چکیده زمینه و هدف: امروزه بسیاری از پروتکلهای ژن درمانی با حامل های لنتی ویروسی انجام می شود. یکی از مهمترین فاکتورهایی که در تکوین پانکراس و رونویسی ژن انسولین نقش دارد فاکتور رونویسی Pancreatic & duodenal homeobox 1 (Pdx-1) است. هدف از این مطالعه بهینهسازی سازه لنتی ویروسی حاوی ژن pdx-1 برای ترانسفکشن سلولهای بنیادی در راستای ژن درمانی دیابت نوع 1 بود. روش بررسی: در این مطالعه تجربی...
Gamma-aminobutyric acid (GABA) is produced and secreted by adult pancreatic β-cells, which also express GABA receptors mediating autocrine signaling and regulating β-cell proliferation. However, whether the autocrine GABA signaling involves in β-cell progenitor development or maturation remains uncertain. By means of immunohistochemistry we analyzed the expression profiles of the GABA synthesiz...
As rapidly developing patient-derived xenografts (PDX) could represent potential sources of cancer stem cells (CSC), we selected and characterized non-cultured PDX cell suspensions from four different renal carcinomas (RCC). Only the cell suspensions from the serial xenografts (PDX-1 and PDX-2) of an undifferentiated RCC (RCC-41) adapted to the selective CSC medium. The cell suspension derived ...
The homeobox factor PDX-1 is a key regulator of pancreatic morphogenesis and glucose homeostasis; targeted disruption of the PDX-1 gene leads to pancreatic agenesis in pdx-1(-/-) homozygotes. Pdx-1 heterozygotes develop normally, but they display glucose intolerance in adulthood. Like certain other homeobox proteins, PDX-1 contains a consensus FPWMK motif that promotes heterodimer formation wit...
KISS1 is a broadly functional secreted proprotein that is then processed into small peptides, termed kisspeptins (KP). Since sequence analysis showed cleavage at KR or RR dibasic sites of the nascent protein, it was hypothesized that enzyme(s) belonging to the proprotein convertase family of proteases process KISS1 to generate KP. To this end, cell lines over-expressing KISS1 were treated with ...
