background and objectives: electric, magnetic and electromagnetic fields can act as stress factors with different effects on biological systems. due to the nutritional and medicinal values, and the increasing electromagnetic radiations, the present study was performed to investigate the effects of the electromagnetic field on the developmental stages and cytotoxic properties of okra. methods: b...
زمینه: گرچه مصرف نانوذرات نقره به دلیل برخورداری از ویژگی های اختصاصی آنتی باکتریال به عنوان ماده اصلی در تولید محصولات سلامت محور مبتنی بر فناوری نانو در حال افزایش است، با این وجود اطلاعات سم شناسی وابسته به هر نمونه از نانو ذرات نقره با توجه به ویژگی های کاملاً اختصاصی آن ها با محوریت ارزیابی ریسک این نانومواد در انسان و محیط زیست محدود است. لذا این مطالعه در نظر دارد تا سمیت سلولی و تغییرات ...
the chloroform soluble fractions of ethanolic extracts of five inula belonging to the compositae family were evaluated for cytotoxic activity against five different cell lines including caco2 (human colon adenocarcinoma), mcf7 (human breast adenocarcinoma), hepg2 (human hepatocellular carcinoma), vero (green african monkey kidney) and wehi164 (balb c mouse fibrosarcoma). cytotoxicity was assess...
Alpha-synuclein (α-SYN) is a central molecule in Parkinson’s disease pathogenesis. Despite several studies, the molecular nature of endogenous α-SYN especially in human brain samples is still not well understood due to the lack of reliable methods and the limited amount of bio-specimens. Here, we introduce α-SYN single-molecule pull-down (α-SYN SiMPull) assay combined with in vivo protein cross...
BACKGROUND Chronic myelogenous leukemia (CML) has unsatisfactory treatment efficacy at present. As the major component of red orpiment, tetra-arsenic tetra-sulfide (As4S4) has been recently used in treating leukemia, but with unclear mechanism targeting CML. MicroRNA (miR) is a group of endogenous non-coding RNAs regulating pathogenesis. MiR181 has been shown to exert important roles in tumor p...
OBJECTIVES To investigate the crucial role of miR-26a in breast cancer and to validate whether miR-26a could regulate proliferation of breast cancer cells by targeting high mobility group AT-hook 1 (HMGA1). METHODS Reverse transcription-polymerase chain reaction (RT-PCR) was used to quantify the expression levels of miR-26a in breast cancer and adjacent non-cancerous breast tissues. MTT, cell...
VirG is outer membrane protein of Shigella and affects the spread of Shigella. Recently it has been reported that apyrase influences the location of VirG, although the underlying mechanism remains poorly understood. The site of interaction between apyrase and VirG is the focus of our research. First we constructed recombinant plasmid pHIS-phoN2 and pS-(v1-1102, v53-758, v759-1102, v53-319, v320...
