Cell migration and invasion are key processes involved during tumor metastasis. Recently, microRNAs (miRs) have been demonstrated to play important roles in the regulation of cancer metastasis. However, the underlying mechanisms remain unknown. Here, we aimed to investigate the exact role of miR-663 in the metastasis of glioblastoma as well as the underlying mechanisms. By performing quantitati...
The novel protein kinase C-beta inhibitor enzastaurin (ENZA) induced apoptosis in LNT-229 and T98G cells whereas A172 cells were resistant. Further, ENZA reduced proliferation in glioblastoma-initiating cells T 269 and T 323 but did not induce apoptosis. ENZA-induced apoptosis involved cleavage of caspases 3, 8, and 9 and led to mitochondrial cytochrome c release and was strongly suppressed by ...
Abstract BACKGROUND Glioblastoma (GBM) is one of the most malignant primary brain tumors. Despite development treatment, prognosis GBM still poor. Here, we identified lomerizine, a prophylactic drug for migraine, as potential anti-GBM from thousands existing compounds. We investigated its therapeutic effects both in vitro and vivo with purpose repositioning. Materials method: Human patient-deri...
Glioblastoma multiforme (GBM) is the most common malignant brain tumour in adults. The poor prognosis and short median overall survival of patients with GBM associated resistance to therapy after surgical adjuvant treatment. expression various acetylcholine receptors (AChR) has been widely reported. present study aimed investigate cholinergic system‑related genes primary explore antiproliferati...
the influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. this study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (olhe). olive leaves were collected from gardens around the city of shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. the influ...
background: rna interference (rnai) is the mechanism of gene silencing-mediated messenger rna degradation by small interference rna (sirna), which becomes a powerful tool for in vivo research, especially in the areas of cancer. in this research, the potential use of an expression vector as a specific sirna producing tool for silencing of bcr-abl in k562 cell line has been investigated. methods:...
expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
زمینه و هدف: مطالعات نشان دادهاند استروئیدهای جنسی بر تکثیر سلولهای سرطانی در سطح سلولی و مولکولی تأثیرگذارند. در این مطالعه به بررسی اثر غلظت سیتوتوکسیک تستوسترون بر بیان ژنهای Bax، Bcl-2 و KAI-1/CD82 در سلولهای آدنوکارسینومای کولورکتال (HT29) و گلایوبلاستومای مغزی (A172) پرداخته شد. روش بررسی: در این مطالعه تجربی - آزمایشگاهی، سلولهای HT29 و A172 به گروههای شاهد و گروههای تحت تأثیر غلظ...
In the presence of a bacteriophage (a bacteria-attacking virus) resistance is clearly beneficial to the bacteria. As expected in such conditions, resistant bacteria emerge rapidly. However, in the absence of the phage, resistant bacteria often display reduced fitness, compared to their sensitive counterparts. The present study explored the fitness cost associated with phage-resistance as an opp...
Nestin, a class VI intermediate filament protein, was originally described as a neuronal stem cell marker during central nervous system development. Nestin is expressed in gliomas, and its expression levels are higher in gliomas with high WHO histopathological classification grades than in those with low grades. In the present study, we examined whether nestin regulates the biological activitie...
