Elevated tumor cyclooxygenase 2 (COX-2) expression is associated with increased angiogenesis, tumor invasion, and promotion of tumor cell resistance to apoptosis. In our previous studies using non-small cell lung cancer (NSCLC) cell lines constitutively expressing COX-2 cDNA in sense and antisense orientations, we demonstrated that constitutive overexpression of COX-2 leads to stabilization of ...
Histone deacetylase (HDAC) inhibitors represent a promising group of anticancer agents. Treatment of cancer cells with HDAC blockers, such as suberoylanilide hydroxamic acid (SAHA), leads to the activation of apoptosis-promoting genes. To enhance proapoptotic efficiency, SAHA has been used in conjunction with radiation, kinase inhibitors, and cytotoxic drugs. In the present study, we show that ...
PURPOSE Enhanced tumor cell survival through expression of inhibitors of apoptosis (IAP) is a hallmark of cancer. Survivin, an IAP absent from most normal tissues, is overexpressed in many malignancies and associated with a poorer prognosis. We report the first-in-human dose study of LY2181308, a second-generation antisense oligonucleotide (ASO) directed against survivin mRNA. PATIENTS AND ME...

Survivin, an IAP absent from most normal tissues, is overexpressed in many malignancies and associated with a poorer prognosis.

The IAPs (inhibitor of apoptosis proteins) are a family of caspase inhibitors that block the execution phase of apoptosis. Overexpression of IAPs confers chemoresistance and, in some groups of patients, is associated with a poor prognosis. Given their role in the development and progression of solid tumors and hematologic malignancies, efforts are underway to develop therapeutic IAP inhibitors,...
The design of multifunctional drug delivery systems capable of simultaneous target detection, imaging, and therapeutics in live mammalian cells is critical for biomedical research. In this study, by using mesoporous silica nanoparticles (MSNs) chemically modified with a small-molecule dark quencher, followed by sequential drug encapsulation, MSN capping with a dye-labeled antisense oligonucleot...
survivin پروتئینی است که مرگ برنامهریزی شده سلول (آپاپتوز) را مهار نموده و چرخه تقسیم سلولی را نیز تنظیم مینماید. این پروتئین به شدت در اغلب تومورهای انسانی بیان میشود، اما در اکثر بافتهای طبیعی تمایزیافته قابل شناسایی نیست. از میان مطالعات مرتبط با تاثیر جهشهای مهارکننده survivin در سلولهای سرطانی، فرم جهشیافته t34a مورد توجه بیشتری قرار گرفته است. نتایج به دست آمده از مدلسازی و شبیه...
Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decades of life. Diagnosis of patients with osteosarcoma is limited to clinico-pathological parameters whereas molecular markers of tumor initiation and promotion have not yet been identified. We aimed to study the expression of the anti-apoptotic survivin gene in osteosarcoma specimens. A total...
