The hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus (NDV) with its immunotherapeutic activities and sialic acid binding abilities is a promising cancer adjuvant. The HN was surfaced displayed on Lactococcus lactis and its cancer targeting ability was investigated via attachment to the MDA-MB231 breast cancers. To surface display the HN protein on the bacterial cell wall, HN ...

The sex steroid hormone progesterone (Pg) is critically involved in the development of the mammary gland, and it also is thought to play a role in breast cancer progression. However, the effect of Pg on malignant phenotypes is not fully understood in breast cancer. We previously reported that in Pg receptor (PR)–positive T47D breast cancer cells, Pg was able to counterbalance the stimulatory ef...

Transforming growth factor-beta1 (TGF-beta1) is a crucial molecule for stimulation of breast cancer invasion and formation of bone metastases. The molecular mechanisms of how TGF-beta1 mediates these effects have yet to be completely determined. We have found that activating transcription factor-3 (ATF-3) is strongly stimulated and its level is sustained by TGF-beta1 in highly invasive and meta...

Background Cancer stem cells play crucial roles in resistance to therapeutic schemes and relapse of disease, so it is important to find targeted therapies that kill them selectively. Breast cancer is the most common cancer in females living in all part of the world including Iran and it has an important burden in public health with direct impact on patients’ families. Breast cancer in young ad...

The aim of the present study was to investigate the radiosensitizing effects of homeobox (HOX) transcript antisense RNA (HOTAIR) long non-coding RNA on breast cancer tumor cells and examine the underlying mechanisms. Recombinant plasmid vectors containing HOTAIR gene were constructed and MDA-MB231 cells were transfected with these plasmids using liposomes. The cells were treated with radiation ...

BACKGROUND Morinda citrifolia L. that was reported with immunomodulating and cytotoxic effects has been traditionally used to treat multiple illnesses including cancer. An anthraquinone derived from fruits of Morinda citrifolia L., nordamnacanthal, is a promising agent possessing several in vitro biological activities. However, the in vivo anti-tumor effects and the safety profile of nordamnaca...

A series of new spiro-heterocycles engrafted spirooxindole/pyrrolidine/thiochromene scaffolds was synthesized by the three-component 1,3-dipolar cycloaddition reactions in a fully controlled regio- and stereo-selective fashion. Condensation several substituted isatin derivatives with L-proline generated azomethine ylides which subsequently reacted chalcones based thiochromene scaffold, finally ...

Retroviral transformation has been associated with pro-proliferative oncogenic signaling in human cells. The current study demonstrates that transduction of human breast carcinoma cells (MDA-MB231) with LXSN and QCXIP retroviral vectors causes significant increases in growth rate, clonogenic fraction, and aldehyde dehydrogenase-1 positive cells (ALDH1+), which is associated with increased stead...

The interaction between cancer and its local microenvironment can determine properties of growth and metastasis. A critical component of the tumor microenvironment in this context is the cancer-associated fibroblast (CAF), which can promote tumor growth, angiogenesis and metastasis. It has been hypothesized that CAF may be derived from mesenchymal stromal cells (MSC), derived from local or dist...
