Cancer stem cells or tumor-initiating cells (CSC/TICs), which can undergo self-renewal and differentiation, are thought to play critical roles in tumorigenesis, therapy resistance, tumor recurrence and metastasis. Tumor recurrence and chemoresistance are major causes of poor survival rates of ovarian cancer patients, which may be due in part to the existence of CSC/TICs. Therefore, elucidating ...
We investigated the metabolic profile of cancer stem cells (CSC) isolated from patients with epithelial ovarian cancer. CSC overexpressed genes associated with glucose uptake, oxidative phosphorylation (OXPHOS), and fatty acid β-oxidation, indicating higher ability to direct pyruvate towards the Krebs cycle. Consistent with a metabolic profile dominated by OXPHOS, the CSC showed higher mitochon...
We have recently demonstrated that human Cardiac Stem Cells isolated from explanted failing hearts (E-CSC) are characterized, in vitro, with respect to those isolated from healthy donors (D-CSC), by a senescent phenotype: a reduced telomere length and telomerase activity, telomere erosion, the occurrence of telomere dysfunction foci and the accumulation of senescent markers, as p16INK4A. In thi...
Individual differences in working memory capacity (WMC) are associated with speech recognition in adverse conditions, reflecting the need to maintain and process speech fragments until lexical access can be achieved. When working memory resources are engaged in unlocking the lexicon, there is less Cognitive Spare Capacity (CSC) available for higher level processing of speech. CSC is essential f...
Estradiol (E2) increases not only the cell growth but also the cancer stem cell (CSC) proportion in estrogen receptor (ER)-positive breast cancer cells. It has been suggested that the non-canonical hedgehog (Hh) pathway activated by E2 plays an important role in the regulation of CSC proportion in ER-positive breast cancer cells. We studied anti-CSC activity of a non-canonical Hh inhibitor GANT...
The cancer stem cell (CSC) model posits that CSCs are a small, biologically distinct subpopulation of cancer cells in each tumor that have self-renewal and multi-lineage potential, and are critical for cancer initiation, metastasis, recurrence, and therapy-resistance. Numerous studies have linked CSCs to thyroid biology, but the candidate markers and signal transduction pathways that drive thyr...
Cross-sectoral cooperation (CSC) has gained recognition as the key to achieving sustainable development goals within a locality. However, existing studies focused on local (SLD) initiatives resulting from CSC remain sparse. This article aims review CSC–SLD literature, using Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method. Research questions were constructed PIC...
The global community's growing enthusiasm for the potential of social accountability approaches to improve health system performance and accelerate health progress makes it imperative that we learn from social accountability intervention implementation experience and results. To this end, we carried out a review of Cooperative for Assistance and Relief Everywhere, Inc. (CARE)'s experience with ...
Melanoma is the most dangerous and treatment-resistant skin cancer. Tumor resistance and recurrence are due to the persistence in the patient of aggressive cells with stem cell features, the cancer stem cells (CSC). Recent evidences have shown that CSC display a distinct metabolic profile as compared to tumor bulk population: a promising anti-tumor strategy is therefore to target specific metab...
Markers that reliably identify cancer stem cells (CSC) in ovarian cancer could assist prognosis and improve strategies for therapy. CD133 is a reported marker of ovarian CSC. Aldehyde dehydrogenase (ALDH) activity is a reported CSC marker in several solid tumors, but it has not been studied in ovarian CSC. Here we report that dual positivity of CD133 and ALDH defines a compelling marker set in ...
