Background: Cancer is one of the major health problems worldwide and natural resources are being explored to develop anticancer drugs with fewer side effects. Iranian propolis contains components including flavonoids and polyphenols and has various medicinal properties. The aim of this study was to investigate the effect of Ethanolic Extract of Sirch Propolis (EESP) on three br...

Increased expression of Bcl-2 protein has been demonstrated in various cancerous and precancerous lesions. The B-cell lymphoma-2 gene is a proto-oncogene that inhibits apoptosis, therefore keeping the cell alive. Mutations leads to an overexpression products leading apoptosis impairment resulting neoplastic changes as consequence. Hence, objective study was investigate fibro epithelial polyp (F...

Background: The induction of bystander effect via ionizing radiation has been well proven. However, few studies have investigated the bystander effect following non-ionizing radiation, such as ultrasound waves. Here, the bystander effect after different sonication times on human melanoma cell line (A375), is evaluated by assessing cell viability and apoptosis. Materials and Methods: The cells w...

The aim of this study was to examine the effect of crude bile on the human HepG2 and CCRF-CEM cell lines. Cells were exposed to different dilutions of bile. Antiproliferative effects were determined by the cytotoxic MTT assay. Cells undergoing apoptosis were identified by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Bile administration resulted in dose-dependent c...

understanding the mechanism of tumor resistance is critical for cancer therapy. in this study, we investigated the effect of carcinoembryonic antigen (cea) overexpression on uv-and 5-fluorouracil (5-fu)-induced apoptosis and autophagy in colorectal cancer cells. we used histone deacetylase (hdac) inhibitor, nab and dna demethylating agent, 5- azacytidine (5-aza) to induce cea expression in ht29...

background and aims: epigallocatechin-3-gallate (egcg) is a polyphenolic compound from green tea, which its anticancer effects on many types of cancers have been confirmed, but the molecular mechanism by which egcg induces apoptosis remains unknown. the aim of the present study was to investigate anti-proliferative properties and apoptotic signaling pathway of egcg on pc3 human prostate cancer ...

Background: Cancer refers to the abnormal growth of cells and is still the most common cause of morbidity in world. The purpose of this study was to determine cytotoxicity effect of high molecular weight (HMWC) and low molecular weight of chitosan (LMWC) on three cancerous cell lines MCF-7, HeLa and Saos-2 with different histological origin. Methods: The anticancer property of two types of chi...
