Molecular Epidemiology of Breast Cancer among Iranian-Azeri Population based on P53 Research

Background: This study was done in order to enhance our understanding about molecular and epidemiological features of breast cancer among the Azeri population with special emphasis on the detection of TP53 mutations. We also analyzed the role of the P53codon72 polymorphism (rs1042522) and its role in susceptibility to breast cancer. Methods: ...

Anti-cancer effects and molecular mechanisms of sour tea (Hibiscus sabdariffa) in the human cellular model (A549) of lung cancer

Background and Aims: Lung cancer is one of the most common malignancies worldwide that despite the recent progress, its existing treatments have not sufficient efficiency, and scientists are always trying to find complementary therapies. Medicinal plants, such as sour tea, have attracted lots of attention due to their abundant antioxidant compounds. In the present study, in addition to assessin...

Molecular mechanisms involved in multidrug resistance in breast cancer therapy

Breast cancer is the most prevalent cancer in women. Chemotherapy is the main strategy in the treatment of this disease especially in the advanced form of the disease. Despite the recent progress in the development of new chemotherapy, the effectiveness of these drugs has dramatically reduced due to multidrug resistance. The phenotype of multidrug resistance (MDR) can occur through different me...

Systemic effects of starved fibroblasts culture supernatant on immunosuppressed rats treated with cancer stem cells

Quantitation of Vascular Endothelial Growth Factor and Interleukin-6 in Different Stages of Breast Cancer

Background: Determination of the impact of angiogenesis on tumor development and progression is essential. This study aimed to determine the serum levels of Vascular endothelial growth factor (VEGF) and Interleukin 6 (IL-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage. Methods: Under aseptic precautions 5 ml of venous blood was collecte...

Inflammation, a Key Factor in Cancer Ambush

Inflammatory condition is the consequence of defensive mechanism of immune system against viral and bacterial infection, tissue injury, UV radiation, stress and etc. Persistently acute inflammation leads to chronic phase which is characterized by production of pro-inflammatory mediators from T cells. These molecules (e.g. IL-6, TNF-&alpha, IL-1&beta and IL-17) are mostly pleiotropic cytokines i...
