background: the adjuvanticity potential of lactobacillus casei was first suggested in an old survey. the present study was designed to investigate the efficacy of a new immunotherapy against breast cancer made by mixing an extract of heated 4t1 mammary carcinoma cell line and a heat-killed preparation of lactobacillus casei. methods: female balb/c mice (6–8 weeks old, n=40) were challenged subc...

background: the 4t1 cells tumor growth and metastatic pattern in balb/c mice very closely mimic human breast cancer. these herbal remedies used in traditional folk medicine have been the source of many medically beneficial drugs. the aim of the current study was to evaluate the anti-proliferative activity of the asafoetida, ginseng and fennel ethanolic extracts on mouse breast cancer 4t1 cell-l...

Background: Cancer is amongst the leading reasons of death in all parts of the world. Breast cancer is also responsible for the largest number of deaths among women population. Several studies confirmed that Bifidobacterium bifidum as a probiotic meaningfully inhibited breast cancer development. The present study aimed to investigate the effect of B. bifidum supernatant on the cell growth inhib...

objective: breast cancer is one of the leading causes of death in women worldwide. conventional treatments use cytotoxic drugs which have high numbers of side effects. currently pharmacologists are searching for novel drugs with fewer side effects and maximum efficiency as breast cancer treatment. the aim of the current study is to clarify the cytotoxicity effect of the recombinant outer membra...

The use of bacteriophages to select novel ligands has been widely explored for cancer therapy. Their application is most warranted in cancer subtypes lacking knowledge on how to target the cancer cells in question, such as the triple negative breast cancer, eventually leading to the development of alternative nanomedicines for cancer therapeutics. Therefore, the following study aimed to select ...

The human breast cancer cell lines MDA-MB-436 and MDA-MB-231, the murine breast cancer cell line 4T1-luc (4T1 cells stably expressing firefly luciferase) and murine Lewis lung carcinoma cells (LLC) were cultivated according to supplier’s instructions (ATCC). The primary low passaged colon cancer cell lines COGA2 and COGA10 were characterized by Vecsey-Semjen et al. and cultured as previously de...

Although the importance of the host tissue microenvironment in cancer progression and metastasis has been established, the spatiotemporal process establishing a cancer metastasis-prone tissue microenvironment remains unknown. In this study, we aim to understand the immunological character of a metastasis-prone microenvironment in a murine 4T1 breast tumor model, by using the activation of nucle...
