- Minichromosome maintenance protein 2 (MCM2) is a key regulator of DNA replication and has been implicated in tumor progression. While previous studies have demonstrated its role in lung cancer stem cells (CSCs), its role in breast cancer remains unclear. This study aimed to investigate whether MCM2 regulates CSCs and epithelial-mesenchymal transition (EMT) in breast cancer. - Source: PubMed

Kim Rae-Kwon - Lung cancer remains the leading cause of cancer-related mortality worldwide, largely due to therapeutic resistance and tumor recurrence. In non-small cell lung cancer (NSCLC), cancer stem cells (CSCs) have emerged as key contributors to tumor persistence and progression. However, accelerated CSC-targeted drug discovery is limited by the lack of scalable and quantitative screening systems capable of capturing stemness-associated phenotypes. Conventional two-dimensional (2D) assays often fail to reflect the architectural and molecular complexity of CSC-enriched tumor populations. Here, we report the establishment of a luciferase-based three-dimensional (3D) NSCLC spheroid platform integrating CSC-like enrichment with a high-throughput quantitative readout. The luminescent signal strongly correlated with spheroid burden and viable cell content. Compared with 2D monolayers, 3D NSCLC spheroids exhibited elevated expression of pluripotency-associated factors, including OCT4, NANOG, and SOX2, and CSC-associated markers, namely CD44, ALDH1A1, and ABCG2, supporting the enrichment of CSC-like subpopulations. As a proof-of-concept, screening of renieramycin T right-half derivatives identified DH_18 as a lead compound in the established 3D NSCLC spheroid model, exhibiting greater potency than DH_19, accompanied by increased apoptosis and reduced CSC-associated proteins in follow-up experimental validation. Integrated network pharmacology incorporating enrichment and protein-protein interaction analyses further mapped DH_18-NSCLC targets to lung CSC-associated networks and pathways related to stemness and aggressive tumor phenotypes, reinforcing the biological relevance of the 3D screening context. Collectively, these findings present a quantitative and scalable 3D NSCLC spheroid platform suitable for CSC-targeted drug screening and nominate DH_18 as a candidate compound with potential activity against stemness-linked molecular networks. - Source: PubMed

Because colorectal cancer stem-like cells (CRCSCs) play a central role in tumor initiation and progression, therapeutic strategies addressing CSC-enriched populations are urgently needed. In this study, we investigated the anticancer effects of emodin, a natural anthraquinone, in CSC-enriched tumorsphere models. Emodin significantly suppressed the viability and self-renewal capacity of HCT116- and SW480-derived CSCs. It induced G0/G1 cell cycle arrest and markedly downregulated stemness-associated markers (CD44, CD133, ALDH1A1, SOX2, NANOG, and OCT4). Importantly, emodin-induced cell death was characterized by mitochondrial dysfunction, increased mitochondrial reactive oxygen species, loss of membrane potential, and nuclear translocation of apoptosis-inducing factor (AIF). This cytotoxicity was not rescued by the pan-caspase inhibitor Z-VAD-FMK, confirming caspase-independent apoptosis. Furthermore, network pharmacology and experimental validation identified GSK3β as a key target. Emodin reduced Wnt/β-catenin signaling by decreasing β-catenin stabilization and nuclear accumulation. Crucially, a rescue experiment utilizing LiCl confirmed that emodin's suppressive effects are mechanistically dependent on the GSK3β/Wnt/β-catenin axis. Collectively, emodin suppresses CRCSC characteristics by downregulating Wnt/β-catenin signaling and inducing AIF-associated caspase-independent apoptosis, highlighting its therapeutic potential against CRC. - Source: PubMed

Ahmadi MahdiehKim Hong LaeJung Hye Jin - There is no specific therapy for triple-negative breast cancer (TNBC), and the recurrence rate is high. Cancer stem cells (CSCs) play an important role in cancer chemoresistance and metastasis, but there is no consensus marker in this type of cancer. The aim of this study was to identify CSC biomarkers in the plasma secretome of TNBC patients. - Source: PubMed

The impairment of endometrial mesenchymal stem/stromal cells (eMSCs) is central to IUA pathogenesis; however, the absence of reliable markers correlating with disease severity and fibrosis has hindered the understanding of their pathological mechanisms and the development of targeted therapies. Here, ALDH1A1 and ALDH1A2 were identified as novel eMSC markers significantly downregulated in IUA patient samples and scar tissue. ALDH eMSCs exhibited superior self-renewal capability, proliferative capacity, decidualization potential, and angiogenic capability, alongside reduced fibrotic characteristics compared to ALDH eMSCs. Transplantation of ALDH eMSCs promoted endometrial regeneration in a murine IUA model. Mechanistically, ALDH eMSCs secreted higher levels of ATRA (all-trans retinoic acid), and their pro-regenerative effect was mediated through the ALDH-RA-RAR (RA Receptor) axis. ATRA and E2 (Estradiol) acted synergistically to promote glandular organoid growth and reprogram ALDH eMSCs towards a regenerative phenotype. The RE-Exo@HA hydrogel, composed of ATRA and E2 encapsulated in exosomes embedded within a hyaluronic acid hydrogel, effectively facilitated scarless endometrial repair, demonstrated by restored endometrial architecture, increased gland number, reduced fibrosis, and significantly improved pregnancy outcomes in vivo. Our findings establish ALDH1A1/ALDH1A2 as key functional markers of a regenerative eMSC subpopulation depleted in IUA and highlight the ALDH-RA axis as a critical mechanism governing endometrial repair. - Source: PubMed
