Cancer stem cells (CSCs) have been identified in a multiple of cancer types and resistant to traditional cancer therapies such as chemotherapeutic agents and radiotherapy, which may destroy bulk tumor cells but not all CSCs, contributing to reformation tumor masses and subsequent relapse. Moreover, it is very difficult to effectively identify and eliminate CSCs because they share some common phenotypic and functional characteristics of normal stem cells. Therefore, finding better therapeutic strategies to selectively target CSCs might be helpful to reduce subsequent malignancies. In the present study, we found that caffeic acid effectively suppresses self-renewal capacity, stem-like characteristics, and migratory capacity of CD44 and CD133 colorectal CSCs and . In addition, we also revealed that PI3K/Akt signaling may be linked to multiple colorectal CSC-associated characteristics, such as radio-resistance, stem-like property, and tumorigenic potential. To the best of our knowledge, this is the first study demonstrating that caffeic acid effectively targets colorectal CSC populations by inhibiting the growth and/or self-renewal capacity of colorectal CSCs through PI3K/Akt signaling and .

Introduction: The development of efficient and sustainable catalytic methodolo-gies has garnered considerable attention in contemporary organic synthesis.
Methods: Herein, we present a novel approach employing the Cu@DPP-SPION catalyst for the synthesis of ethyl 4-(aryl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate derivatives. This versatile catalytic system incorporates copper nanoparticles supported on 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)benzoic acid-functionalized superparamagnetic iron oxide nanoparticles (SPIONs).

Background: Malaria is one of the leading causes of morbidity and/or mortality in tropical Africa. The spread and development of resistance to chemical antimalarial drugs and the relatively high cost of the latter are problems associated with malaria control and are reasons to promote the use of plants to meet healthcare needs to treat malaria. The aim of this study was to evaluate antiplasmodial activities of extracts of (Mah quat), which is traditionally used for the treatment of malaria in the western region of Cameroon.

Flatworms depend on stem cells for continued tissue growth and renewal during their life cycles, making these cells valuable drug targets. While neoblasts are extensively characterized in the free-living planarian , and similar stem cells have been characterized in the trematode , their identification and characterization in cestodes is just emerging. Since stem cells are generally affected by irradiation, in this work we used this experimental approach to study the stem cells of the model cestode .

In this editorial, we will discuss the article by Tang published in the recent issue of the . They explored an innovative approach to enhancing gemcitabine (GEM) delivery and efficacy using human bone marrow mesenchymal stem cells (HU-BMSCs)-derived exosomes. The manufacture of GEM-loaded HU-BMSCs-derived exosomes (Exo-GEM) has been optimized.
