objective: breast cancer is the second leading cause of cancer death in women. cisplatin is a traditional cancer drug commonly used in chemotherapy for killing cancer cells. modulation at the mrna levels of apoptotic related genes often correlate with the sensitivity of various types of cancer cells to chemotherapeutic agents. nanoparticulate drug delivery systems are being developed to effecti...

malignant tumors of head and neck carcinomas are the sixth most common type of cancer. current systemic therapies for cancer show side effects in normal tissues and short-term efficacy due to drug resistance. consequently, there is much interest in identifying new drugs for cancer treatment. crocin (an active ingredient of saffron) has been shown to have cytotoxic effects on cancer cell lines. ...

background: nigella sativa has been a nutritional flavoring factor and natural treatment for many ailments for so many years in medical science. earlier studies have been reported that thymoquinone (tq), an active compound of its seed, contains anticancer properties. previous studies have shown that tq induces apoptosis in breast cancer cells but it is unclear the role of p53 in the apoptotic p...

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...

In a systematic effort to identify a potent antiproliferative agent, four complexes of vanadium containing maltol and deferiprone ligands were synthesized and evaluated for their cytotoxic activity against five human and animal cancer cell lines, including human breast cancer cells (MCF-7), human cervix epithelial carcinoma (HeLa), human colon cancer cell line (HT-29), human leukemia cell line ...

Background: Regulatory T Cells (Tregs) and Myeloid-Derived Suppressor Cells (MDSCs) are two main regulatory cells modulating the immune responses in inflammation and cancer. Objective: To investigate and compare Tregs and MDSCs in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dyspepsia (NUD, n=22), peptic ulcer disease...

cancer is a genetic-epigenetic based disease which contains a complex of alterations that cause irreversible transformation of cells with a new anarchic behavior. tumor suppressor inactivation and/or oncogene activation will lead to tumorigenesis. based on the genetic alteration in germ or somatic cells, the affected person will have a different fate of cancer incidence or inheritable cancer su...
