objective(s): glioblastoma is the most lethal tumor of the central nervous system. here, we aimed to evaluate the effects of exogenous delivery of p53 and a nanoformulation of curcumin called dendrosomal curcumin (dnc), alone and in combination, on glioblastoma tumor cells. materials and methods: mtt assay was exploited to measure the viability of u87-mg cells against dnc treatment. cells were ...

Objective(s):Eukaryotic translation initiation factor 4E (eIF4E) is overexpressed in cervical cancer (CC). However, the molecular mechanisms are unclear. This study aimed to investigate the molecular mechanism of eIF4E gene overexpression in CC. Materials andMethods:The human papillomavirus (HPV) type 18 E7 and eIF4E mRNAs were measured following knock down or overexpression of E7 gene by RT-P...

conclusions the findings show fluconazole -resistance in c. albicans isolates with overexpression of pir1p. results in the 52 isolates, 49 (94%) were resistant to fluconazole. overexpression of pir1 gene was detected in 47 (96%) fluconazole-resistant c. albicans isolates. patients and methods a total of 52l vaginal samples were obtained from the females with c. albicans vaginitis. the azole sus...

the p53 protein is expressed in all normal cells and appears to function in cell cycle regulation. abnormally higli levels of the protein are found in many different types of cancer. in breast cancer, overexpression of p53 is associated with point mutations within highly conserved regions of the p53 gene. these altered genes encode stable p53 protein that can be detected by standard immunohisto...

Role of the protein overexpression is very important in the pathogenesis, diagnosis and prognosis of neoplasia. Cases of overexpression of p53 and Ki67 proteins were investigated in 19 ocular squamous cell carcinomas (OSCC) in dairy cows. Microscopically, insix cases the tumors were carcinoma in situ (noninvasive carcinoma, G0), and in the remaining 13 cases the tumors were invasive carcinoma. ...

Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...

Introduction: Bacteria have at least one sigma factor (σ-factor) that transcribes the genes required for cell viability. Usually, transcription of σ-factors occurs and changes in response to a variety of environmental stresses. Expression of σ-factors is one of the strategies which is used in response to different stress conditions. This study was aimed to evaluate the effects...
