La estructura de la ftalimida es considerada un bloque construcción para el desarrollo nuevos agentes anticancerígenos. En este trabajo, se evaluó actividad antiproliferativa cuarenta y tres derivados contra las líneas celulares cancerígenas cérvix (HeLa), hígado (HepG2), mama (4T1), línea celular normal fibroblastos murinos (3T3). Por último, realizó análisis acoplamiento molecular los en siti...

Results Daily oral dose of thalidomide was able to reduce in 46% the tumor volume. Assessment of tumor vascularization revealed a significant decrease in blood vessels formation by thalidomide. The levels of two cytokines, VEGF and TNF-a were decreased in tumor samples of thalidomidetreated group compared with the control group. Accumulation of neutrophils or macrophages in the 4T1 tumor measur...

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...

Objective(s): The central role of molecular imaging modalities in cancer management is an undeniable fact that could help to diagnose cancer tumors in early stages. The main aim of this study is to prepare a novel targeted molecular imaging nanoprobe of CD24-PEGylated Au NPs to improve the ability of Computed tomography scanning (CT scan) outputs for both in vitro and in vivo detection of breas...

The aim of the present study was to investigate the effect of matrine on breast cancer and its underlying mechanism. Matrine is a major component of Sophora flavescens, exhibited antitumor activity in a number of neoplasms, including breast cancer. The present study revealed that matrine inhibited cell viability and induced apoptosis in 4T1 and MCF-7 cells in a dose- and time-dependent manner i...

Prognosis of metastatic breast cancer is very poor which urges the necessity to develop novel potential drug candidates. We assessed two compounds with tri-aryl structures (A and B) for their potency to reduce primary breast tumor growth and lung metastasis in 4T1 mice model. MTT assay, 4T1 mammary mouse model and immunohistochemistry experiments were used in this study. In vitro results exhibi...

Radiotherapy is a standard treatment after conservative breast cancer surgery. However, cancers relapsing within a previously irradiated area have an increased probability to metastasize. The mechanisms responsible for this aggressiveness remain unclear. Here, we used the clinically relevant 4T1 breast cancer model mimicking aggressive local relapse after radiotherapy to identify differences be...

MCP-1/CCL2 plays an important role in the initiation and progression of cancer. Since tumor cells produce MCP-1, they are considered to be the main source of this chemokine. Here, we examined whether MCP-1 produced by non-tumor cells affects the growth and lung metastasis of 4T1 breast cancer cells by transplanting them into the mammary pad of WT or MCP-1(-/-) mice. Primary tumors at the inject...
