HuR is an mRNA-binding protein whose overexpression in cancer cells has been associated with poor prognosis and resistance to therapy. While reports on HuR overexpression contributing to chemoresistance exist, limited information is available on HuR and radioresistance especially in triple-negative breast cancer (TNBC).In this study we investigated the role of HuR in radiation resistance in thr...

Triple-negative breast cancer (TNBC) is more aggressive than other breast cancer subtypes. Collagen type IV alpha 2 (COL4A2), a major component of the basement membrane, dynamically influences a wide range of biological processes, including cancer pathogenesis and progression. This study evaluated the effects of COL4A2 siRNA delivered by lentiviral vector to TNBC cells. COL4A2 siRNA lenti-viral...

Breast cancer is the most abundant cancer worldwide and a severe problem for women. Notably, breast cancer has a high mortality rate, mainly because of tumor progression and metastasis. Triple-negative breast cancer (TNBC) is highly progressive and lacks the expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Therefore, there ar...

BACKGROUND The aim of this study was to investigate the anticancer activity and mechanism of action of Noscapine alone and in combination with Doxorubicin against triple negative breast cancer (TNBC). METHODS TNBC cells were pretreated with Noscapine or Doxorubicin or combination and combination index values were calculated using isobolographic method. Apoptosis was assessed by TUNEL staining...

background: flavonoids have a variety of biological activities, such as anti-allergic, anti-inflammatory, anti-oxidative, free radical scavenging, and anti-mutagenic. methods: the cytotoxic effects of three synthesized flavonoid derivatives (k3, k4 and k5) were evaluated against hela , mda-mb -231 and ht-29 cancer cells using mtt assay. results: the results showed that these flavonoids were not...

background: understanding of cellular and molecular mechanisms involved in cell/tumor growth and progression has led to molecular-targeted therapy. her1 and her2 are two main oncogenic components of her-receptor family considered as targets for cancer research and therapy. reliable results of her- related research and targeted therapies dependent upon cell line with known her expression status....

Background: Flavonoids have a variety of biological activities, such as anti-allergic, anti-inflammatory, anti-oxidative, free radical scavenging, and anti-mutagenic. Methods: The cytotoxic effects of three synthesized flavonoid derivatives (K3, K4 and K5) were evaluated against Hela , MDA-MB -231 and HT-29 cancer cells using MTT assay. Results: The results showed that these flavonoids were n...
