We investigate the anti-cancer stem cell (CSC) properties of two copper(II) complexes containing 4,7-diphenyl-1,10-phenanthroline and a S, N, X-Schiff base ligand, where X=O (1) or S (2). Complex 1 was previously reported by us, is first metal complex to induce cytotoxic immunogenic death breast CSCs. 2 structural analogue 1, phenolate moiety (within Schiff ligand) replaced thiophenolate group....

Clinical advancement in cancer treatment has improved patient's outcome. Despite these advancements, cancer continues to remain amajor clinical problem.However, treatment has been hindered by the ability of cancer to remain dormant for later resurgence. This review discusses dormant breast cancer (BC) with an emphasis on cancer stem cells (CSCs). BC cells (BCCs) havepreference for thebonemarrow...

Cancer stem cells (CSCs) form a small proportion of tumor cells that have stem cell properties: self-renewal capacity, the ability to develop into different lineages and proliferative potential. The interest in CSCs emerged from their expected role in initiation, progression and recurrence of many tumors. They are generally resistant to conventional chemotherapy and radiotherapy. There are two ...

The cancer stem cell theory hypothesizes that cancer stem cells (CSCs), which possess self-renewal and other stem cell properties, are regarded as the cause of tumor formation, recurrence and metastasis. The isolation and identification of CSCs could help to develop novel therapeutic strategies specifically targeting CSCs. In this study, we enrich...

Accumulating evidence supports that cancer stem cells (CSCs) are responsible for tumor initiation, progression, distal metastasis and even drug resistance. Although CD90 has been identified as a marker for several types of stem cells, such as liver CSCs, the potential role of CD90 as a marker for lung CSCs has yet to be fully characterized. Our previous study demonstrated that the lung cancer s...

Accumulating evidence has shown that cancer stem cells (CSCs) have a tumour-initiating capacity and play crucial roles in tumour metastasis, relapse and chemo/radio-resistance. As tumour propagation initiators, CSCs are considered to be promising targets for obtaining a better therapeutic outcome. Cervical carcinoma is the most common gynaecological malignancy and has a high cancer mortality ra...

Cancer stem cells (CSCs) are highly associated with therapy resistance and metastasis. Interplay between CSCs and various immune components is required for tumor survival. However, the response of CSCs to complement surveillance remains unknown. Herein, using stem-like sphere-forming cells prepared from a mammary tumor and a lung adenocarcinoma cell line, we found that CD59 was upregulated to p...

Great successes in identification and deciphering of mechanisms of the adult stem cells regulation have given rise to the idea that stem cells can also function in tumors as central elements of their development, starting from the initial stage and continuing until metastasis. Such cells were called cancer stem cells (CSCs). Over the course of intense discussion, the CSCs hypothesis gradually b...

Insulin-like growth factor II (IGF2) is maternally imprinted in most tissues, but the epigenetic regulation of the gene in cancer stem cells (CSCs) has not been defined. To study the epigenetic mechanisms underlying self-renewal, we isolated CSCs and non-CSCs from colon cancer (HT29, HRT18, HCT116), hepatoma (Hep3B), breast cancer (MCF7) and prostate cancer (ASPC) cell lines. In HT29 and HRT18 ...
