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-pc...

Objective(s): T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignant tumor. Administration of chemical compounds influencing apoptosis and T cell development has been discussed as promising novel therapeutic strategies. Valproic acid (VPA) as a recently emerged anti-neoplastic histone deacetylase (HDAC) inhibitor and pioglitazone (PGZ) as a high-affinity peroxisome p...

Dates fruit has been used as staple food in the Middle East for thousands of years and various types of dates are found worldwide. Dates and their constituents show various roles in diseases prevention and treatment through anti-oxidant, anti-inflammatory, anti-bacterial activity. In the present study we investigated the activity of aqueous and n-hexane extracts of Phoenix dactylifera L. fruit ...

Background: Melanoma is a common and malignant cutaneous tumor, which is responsible for a large proportion of skin cancer deaths. Dendritic cell (DC)-based vaccines have achieved positive results in the treatment of melanoma because of their ability to induce cytotoxic response to facilitate tumor elimination. Objective: To improve the efficacy of dendritic ce...

background: a growing body of preclinical data indicates that statins may possess antineoplastic properties however, some studies have raised the possibility that statins may also have carcinogenic potential. methods: an air pouch model was used for angiogenesis. single or multiple applications of croton oil on the back of swiss albino mice with or without initiation by dimethylbenz(a)antherace...

we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...

Chemical investigation of Garcinia eugenifolia and Calophyllum enervosum yielded six compounds. One of these was found to be a novel compound identified as enervosanone. Five known compounds cambogin, epicatechin, osajaxanthone, rubraxanthone and isocowanol, were also isolated. These compounds were tested for their bioactivity as antimicrobial, antioxidant and cytotoxicagents. Antimicrobial...

introduction: the native inability of nervous system to regenerate, encourage researchers to consider neural tissue engineering as a potential treatment for spinal cord injuries. considering the suitable characteristics of induced pluripotent stem cells (ipscs) for tissue regeneration applications, in this study we investigated the adhesion, viability and proliferation of neural progenitors (de...

spermatogonia are the male germ line stem cells whose life long expansion is needed for permanent production of spermatozoa. the present study was designed to examine the effect of hcg treatment on germ cell proliferation following stem cell transplantation in mice. spermatogonial stem cells were isolated from neonatal mice testes and characterized by alkaline phosphatase, immunoreactivity and ...

background micrornas are small and non-coding rna molecules with approximately 22 nt in length that cause inhibition of translation or degradation of mrna. mir-155 is a kind of molecule with different functions, such as its role in proliferation, apoptosis, inflammation, differentiation, and immunity. one of its best known functions is apoptosis that affects on caspase-3 activity. the main aim ...
