Summary: The interplay between epithelial-mesenchymal plasticity and cancer stem cells plays a crucial role in cancer progression, affecting the aggressiveness of tumor cells and their response to treatment. Understanding the dynamic nature of EMT as a hybrid state rather than a binary model is important for unraveling the complexities of cancer biology and developing targeted therapeutic interventions.

Summary: Primary breast cancer stem cell (BCSC) cultures isolated from TNBC specimens have been established and shown to grow as tumor spheres under anchorage-independent culture conditions in vitro, while reliably forming tumors in mice when transplanted in limiting dilutions in vivo. Additionally, these BCSC xenograft tumors exhibit similar architecture and gene expression to the original patient tumor, suggesting a promising model for researching BCSC biology and testing new treatment options for TNBC.

Summary: CTNNAL1 is a protein involved in cell-cell adhesion and has been found to have various roles in cancer development and progression. It acts as a cancer suppressor gene in breast cancer, but as a cancer driver gene in melanoma and lung cancer. This study reveals that CTNNAL1 regulates cancer stem cells (CSCs) in lung cancer and glioblastoma, affecting their ability to migrate, invade, and resist treatments like irradiation. Furthermore, CTNNAL1 is also involved in the secretion of CCL2, a chemokine known to influence malignancy and metastasis in cancer. These findings suggest that CTNNAL1 may serve as a potential target for treating lung CSCs and glioma stem cells, as well as a marker of malignancy.

Summary: Connexins are a family of proteins that play a crucial role in cellular communication, but certain types may have pro-tumorigenic effects. Research has shown that Cx46 can modulate the characteristics of cancer stem cells and epithelial-to-mesenchymal transition in breast cancer cells, potentially influencing future cancer therapies.

Summary: The study developed a predictive model for the epithelial-to-mesenchymal transition (EMT) subtype of gastric cancer using computed tomography (CT) images and known clinicopathologic variables. A nomogram was constructed for individualized estimation of EMT subtype, providing a useful screening tool for personalized medicine.

Summary: This study reveals that KRAS activation in gastric cancer stem-like cells (CSCs) enhances the secretion of pro-angiogenic factors and promotes tumor progression and metastasis. Inhibition of KRAS significantly reduces the secretion of factors such as VEGF-A, which are important for tumor angiogenesis. Additionally, high expression of the gastric CSC marker CD44 is associated with expression of both KRAS and VEGF-A, and predicts worse overall survival in gastric cancer patients.

Summary: Tumor cells have the ability to transform into cancer stem cells under the influence of the tumor environment, which are relatively quiescent and exhibit a specific metabolism. Understanding this process could lead to the development of targeted therapies to eradicate cancer more effectively.

Summary: The ability of cancer cells to detach from the primary site and metastasize is the main cause of cancer-related death. The first event in the metastatic cascade is epithelial-to-mesenchymal transition (EMT), which leads to the loss of cell-cell adhesion and the acquisition of motile and stem-like phenotypes. The tumor microenvironment (TME) plays a critical role in modulating EMT in cancer cells, promoting the acquisition of a mesenchymal phenotype through interaction or changes with cancer cells.

Summary: CD44 serves as a marker of cancer stem cells in many tumors, with alternative splicing generating various isoforms. This study reveals a novel mechanism where TGF-beta 1 induces CD44 alternative splicing, promoting epithelial-to-mesenchymal transition and stemness in prostate cancer cells. The findings demonstrate the important roles of CD44 isoforms and TGF-beta 1 in tumor progression.

Summary: This paper reviews the pathogenic mechanisms by which H. pylori induces gastric stem cell-like properties and CSCs, and supplements the existing Correa model. H. pylori infection leads to dysfunction of developmental signaling pathways and alteration of gastric mucosal microenvironment, potentially promoting gastric stem cell-like properties through epithelial-mesenchymal transition.
