Aptamers are molecules that reveal highly complex and refined molecular recognition properties. These molecules are capable of binding with high affinity and selectivity to targets, ranging from small molecules to whole living cells. Several aptamers have been selected for targeting cellular proteins and they have also used in developing therapeutics and diagnostic strategies. Epithelial cell adhesion molecule (EpCAM) is considered as a cancer stem cell (CSC) biomarker and one of the most promising targets for aptamer selection against CSCs...

Cancer stem cells (CSCs) play a central role in the development of breast cancer. The canonical Wnt/β-catenin signal pathway is critical for maintaining CSCs characteristics. Diallyl trisulfide (DATS), a natural organosulfur compound from the garlic, exhibits effective antitumor properties. However, the role of DATS in regulating breast CSCs activity and the underlying molecular mechanisms remain obscure. In the present study, we reported that DATS efficiently inhibited the viability of breast CSCs as evidenced by reducing turmorspheres formation, decreasing the expression of breast CSCs markers (CD44, ALDH1A1, Nanog and Oct4), as well as inhibiting proliferation and inducing apoptosis...

Eliminating cancer stem cells (CSCs) is a key issue in eradicating tumor. The streptavidin-granulocyte -macrophage colony stimulating factor (SA-GM-CSF) surface-modified bladder cancer stem cells vaccine previously developed using our protein-anchor technology could effectively induce specific immune response for eliminating CSCs. However, program death receptor-1 (PD-1)/program death ligand 1 (PD-L1) signaling in tumor microenvironment results in tumor adaptive immune resistance. Although the CSCs vaccine could increase the number of CD8+ T-cells, a part of these CD8+ T-cells expressed PD-1...

Metastasis is the cause of most (>90%) cancer deaths and currently lacks effective treatments. Approaches to understanding the biological process, unraveling the most effective molecular target(s), and implementing nanotechnology to increase the therapeutic index are expected to facilitate cancer therapy against metastasis. Here, we demonstrate the potential advantages of bringing these three approaches together through the rational design of a small interfering RNA (siRNA) that targets p70S6K in cancer stem cells (CSCs) in combination with dendrimer nanotechnology-based siRNA delivery...

Cancer stem cells (CSCs) are small subpopulations of neoplastic cells within a tumor, which have self-renewal and differentiation abilities and could generate new tumors with few cells. Researches have showed that CSCs are considered the most likely reason for cancer recurrence and metastasis. Accumulating evidences have showed that traditional Chinese medicine (TCM) has significant effect on CSCs. It could inhibit the proliferation, self-renew, and multidifferentiation of CSCs. We aimed to summarize the theories of CSCs in TCM, the inhibitory effect, and the pathway on CSCs of TCM...

PURPOSE: Liver metastasis is the major and direct cause of death in patients with uveal melanoma (UM). There is no effective therapy for patients with metastatic UM. Improved treatments of hepatic metastatic patients with UM were urgently needed. Inspired by readily detectable key components in neddylation pathway in UM cells, we aimed at exploring whether neddylation pathway was a therapeutic target for liver metastatic UM. EXPERIMENTAL DESIGN: Expression of key proteins in neddylation pathway in UM was detected by Western blotting, real-time quantitative RT-PCR (qRT-PCR), and immunohistochemical staining...

Cardiac hypertrophy is recognized as an independent risk factor for cardiac failure. Efficient management of hypertensive heart disease requires identification of factors that can possibly mediate the transition from hypertrophy to failure. Resident cardiac stem cells have a prominent role in the maintenance of cardiac tissue homeostasis. Decline in the proportion of healthy cardiac stem cells (CSCs) can affect tissue regeneration. In pathological conditions, apart from natural aging, an adverse microenvironment can lead to decrease in efficiency of CSCs...

Triple-negative breast cancer (TNBC), the deadliest form of this disease, lacks a targeted therapy. TNBC tumors that fail to respond to chemotherapy are characterized by a repressed IFN/signal transducer and activator of transcription (IFN/STAT) gene signature and are often enriched for cancer stem cells (CSCs). We have found that human mammary epithelial cells that undergo an epithelial-to-mesenchymal transition (EMT) following transformation acquire CSC properties. These mesenchymal/CSCs have a significantly repressed IFN/STAT gene expression signature and an enhanced ability to migrate and form tumor spheres...

Adequate iron levels are essential for human health. However, iron overload can act as catalyst for the formation of free radicals, which may cause cancer. Cancer stem cells (CSCs), which maintain the hallmark stem cell characteristics of self-renewal and differentiation capacity, have been proposed as a driving force of tumorigenesis and metastases. In the present study, we investigated the role of iron in the proliferation and stemness of CSCs, using the miPS-LLCcm cell model. Although the anti-cancer agents fluorouracil and cisplatin suppressed the proliferation of miPS-LLCcm cells, these drugs did not alter the expression of stemness markers, including Nanog, SOX2, c-Myc, Oct3/4 and Klf4...

Characterization of the stem-like properties of cancer stem cells (CSCs) remain indirect and qualitative, especially the ability of CSCs to undergo asymmetric cell division for self renewal and differentiation, a unique property of cells of stem origin. It is partly due to the lack of stable cellular models of CSCs. In this study, we developed a new approach for CSC isolation and purification to derive a CSC-enriched cell line (LLC-SE). By conducting five consecutive rounds of single cell cloning using the LLC-SE cell line, we obtained two distinct sub-population of cells within the Lewis lung cancer CSCs that employed largely symmetric division for self-renewal (LLC-SD) or underwent asymmetric division for differentiation (LLC-ASD)...

Retinoid X receptor-α (RXRα) is a kind of nuclear receptor and is a target of cancer prevention and treatment in various types of cancers. Cancer stem cells (CSCs) are regarded as the main cause of carcinoma metastasis, tumor recurrence and chemotherapy resistance. So far, the mechanism how RXRα regulates CSCs remains unknown. In the present study, we found that RXRα was up-regulated in head and neck squamous cell carcinoma (HNSCC) tissues and the enriched HNSCC cancer stem cells. Over-expression of RXRα was able to expand the CSC-like properties in HNSCC cells, while knockdown of RXRα could repress the stemness respectively...

Cancer stem-like cells (CSCs) are a cell subpopulation that can reinitiate tumors, resist chemotherapy, give rise to metastases and lead to disease relapse because of an acquired resistance to apoptosis. Especially, epigenetic alterations play a crucial role in the regulation of stemness and also have been implicated in the development of drug resistance. Hence, in the present study, we examined the cytotoxic and apoptotic activity of valproic acid (VPA) as an inhibitor of histone deacetylases (HDACs) against breast CSCs (BCSCs)...

Neuroblastoma (NB) is an aggressive pediatric cancer that originates from neural crest tissues of the sympathetic nervous system. NB is highly heterogeneous both from a clinical and a molecular perspective. Clinically, this cancer represents a wide range of phenotypes ranging from spontaneous regression of 4S disease to unremitting treatment-refractory progression and death of high-risk metastatic disease. At a cellular level, the heterogeneous behavior of NB likely arises from an arrest and deregulation of normal neural crest development...

Circular RNAs (circRNAs), a novel type of noncoding RNAs (ncRNAs), have been shown to be implicated in biological processes including cancer as gene expression regulators. However, the roles of circRNAs in cancer stem cells (CSCs) have been unexplored. In the present study, we screened the circRNA profile in breast cancer stem cells (BCSCs) using RNA-Sequencing. Here, 27 circRNAs were found to be aberrantly expressed. Of these, 19 circRNAs were downregulated and 8 were upregulated and some of these circRNAs were validated by Q-PCR...

Glioblastoma multiforme (GBM) is one of the most malignant and aggressive brain tumors with great amount of hyaluronan (HA) secretion and CD44 overexpression (HA receptor). CD44 has been suggested as a cancer stem cells (CSCs) marker. However, several clinical studies have indicated that CD44low glioma cell exhibit CSCs traits. Additionally, our previous study indicated that more CD44 expression was associated with a better prognosis in GBM patients. To determine whether CD44 is an appropriate marker of glioma stem cells (GSCs), we manipulated CD44 expression using intrinsic (CD44 knockdown, CD44kd) and extrinsic (HA supplement, HA+) methods...
