cancer stem cells (cscs) have been defined as a unique subpopulation in tumors, endowed with the capacity to initiate tumor progression, maintain self-renewal as well as metastatic potential. recently, more evidence strongly indicates the existence of cscs in solid tumors of wide variety of organs such as breast, brain and stomach. recent studies suggest that a special subpopulation of gastric ...

Cancer stem cells (CSCs) are known as the major reason for therapy resistance. Recently, natural herbal compounds are suggested to have a significant role in inhibiting the breast cancer stem cells (BCSCs). The aim of this study was to explore the effective natural herbal compounds against BCSCs.This review article was designed based on the BCSCs, mechanisms of therapy resistance and natural he...

Abstract Purpose: our goal is to reduce the release rate of methotrexate (MTX) and increase cell death efficiency. Methods: Carboxylated multi-walled carbon nanotubes (MWCNT-COOH) were functionalized with MTX as a cytotoxic agent, FA as a targeting moiety and polyethylene amine (PEI) as a hydrophilic agent. Ultimately, MWCNT-MTX and MWCNT-MTX-PEI-FA were synthesized. Methotrexate re...

the present study , was an attempt to develop galactosylated albumin nanoparticles of simvastatin for treatment of hypercholesterolemia. by developing the galactosylated nanoparticulated delivery the required action of drug at the target site at liver can be provided. the advantage of targeting helps to reduce the systemic side effects which may be occur due to the distribution of the drug to t...

background: chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. in this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines.   methods: in a descriptive study, gene expression profile of ccr1, ccr6, ccr7, ccr9, cxcr1, ...

Cancer Chemo-Immunotherapy In article number 2103497, Yubin Huang, Dongfang Zhou, and co-workers demonstrate an engineered endogenous tumor-associated macrophages (TAMs)-targeting biomimetic nano-red-blood-cell (RBC) system to deliver chemotherapeutic doxorubicin oxygen for enhanced cancer chemo-immunotherapy. TAMs-targeting depletion hypoxia alleviation synergistically reprogram the tumor immu...

Introduction: A main choice for cancer treatment is radiotherapy. But, the radiotherapy disadvantage is damages caused by radiation given to normal tissues/organs surrounding cancer. One way to avoid this is via increasing radiosensitization of cancer cells. Gold nanoparticles (GNPs) have shown sensitizing effect on cancer cells by enhancing their absorbed dose. Unlike earlier ...

although the conventional therapies have obviously improved the conditions of patients with cancer, some mechanisms of resistance have led scientists to use alternative agents that can penetrate in most solid tumors. furthermore, the success of cancer therapies depends on limiting the uptake of toxins to normal tissues and their selectivity to malignant cells. the involvement of natural and gen...

Cancer stem cells (CSCs) have been identified as rare cellular populations in many cancers, including leukemia and solid tumors. This minor subpopulation of cancerous cells is immortal tumor-initiating cells which thought to be responsible for cancer initiation, progression, metastasis, recurrence and drug/radiation resistance. Low proliferative rate, high self-renewing capacity, differentiatio...
