BACKGROUND Achaete scute-like 2 (Ascl2), a basic helix-loop-helix (bHLH) transcription factor, controls the fate of intestinal stem cells. However, the role of Ascl2 in colon cancer progenitor cells remains unknown. The cell line HT-29 (47.5-95% of CD133(+) population) and LS174T (0.45% of CD133(+) population) were chosen for functional evaluation of Ascl2 in colon cancer progenitor cells after...
Silencing of gene expression by RNA interference (RNAi) has become a widely used tool. For the study of mammalian gene function expression vectors for short hairpin RNA (shRNA) were developed. However the standard methods of shRNA transgenic (Tg) mice production have not been established. Sry (sexdetermining region on the Y chromosome) is a mammalian sex-determining gene on the Y chromosome. In...
BACKGROUND Rift Valley fever virus (RVFV), a member of the Bunyaviridae family, may cause severe hepatitis, encephalitis and haemorrhagic fever in humans. There are currently no available licensed vaccines or therapies to treat the viral infection in humans. RNA interference (RNAi)-based viral gene silencing offers a promising approach to inhibiting replication of this highly pathogenic virus. ...
Despite the broad repertoire of loss of function (LOF) tools available for use in the zebrafish, there remains a need for a simple and rapid method that can inhibit expression of genes at later stages. RNAi would fulfill that role, and a previous report (Dong et al. 2009) provided encouraging data. The goal of this study was to further address the ability of expressed shRNAs to inhibit gene exp...
هدف: در پژوهش حاضر بیان ژن Cdc42 در سلول‌های Calu-6 مربوط به کارسینومای ریه با استفاده از سیستم مهاری shRNA کاهش یافته و اثرات این کاهش بر رشد و تکثیر سلولی بررسی شد.مواد و روش‌ها: بهمنظور کاهش بیان ژن Cdc42 از مکانیسم مهاری shRNA استفاده شد. سیستم لنتی‌ویروسی برای رسانش shRNA اختصاصی ژن Cdc42 به سلول‌های Calu-6 انتخاب شد. لنتی‌ویروس‌های نوترکیب بهکمک ...
Transcripts possessing a 5'-triphosphate are a hallmark of viral transcription and can trigger the host antiviral response. 5'-triphosphates are also found on common host transcripts transcribed by RNA polymerase III (RNAP III), yet how these transcripts remain non-immunostimulatory is incompletely understood. Most microRNAs (miRNAs) are 5'-monophosphorylated as a result of sequential endonucle...
BACKGROUND Cervical cancer is the second most common female cancer worldwide. Inhibitors of apoptosis proteins (IAPs) block apoptosis; therefore, therapeutic strategies targeting IAPs have attracted the interest of researchers in recent years. Apollon, a member of IAPs, inhibits apoptosis and cell death. RNA interference is a pathway in which small interfering RNA (siRNA) or shRNA (short hairpi...
The CXC receptor-1 (CXCR1) is a coreceptor for interleukin-8 (IL-8) and is expressed on both normal and tumor cells. The function of CXCR1 in prostate cancer was investigated by silencing its expression, using RNA interference. We established stable cell colonies of PC-3 cells, depleted of CXCR1, using lentiviral plasmids (pLK0.1puro) generating small hairpin RNA (shRNA) against CXCR1 mRNA. Sta...
