Abstract
Breast cancer is a significant and deadly threat to women globally. Moreover, Breast cancer metastasis is a complicated process involving multiple biological stages, which is considered a substantial cause of death, where cancer cells spread from the original tumor to other organs in the body-representing the primary mortality factor. Circulating tumor cells (CTCs) are cancer cells detached from the primary or metastatic tumor and enter the bloodstream, allowing them to establish new metastatic sites. CTCs can travel alone or in groups called CTC clusters. Studies have shown that CTC clusters have more potential for metastasis and a poorer prognosis than individual CTCs in breast cancer patients. However, our understanding of CTC clusters' formation, structure, function, and detection is still limited. This review summarizes the current knowledge of CTC clusters' biological properties, isolation, and prognostic significance in breast cancer. It also highlights the challenges and future directions for research and clinical application of CTC clusters.

[PMID: 38139030 PMCID: PMC10742837 DOI: 10.3390/ijms242417199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 11/30/2023] [Accepted: 12/04/2023] [Indexed: 12/24/2023] Open
Abstract
Cancer cell dissemination involves invasion, migration, resistance to stressors in the circulation, extravasation, colonization, and other functions responsible for macroscopic metastases. By enhancing invasiveness, motility, and intravasation, the epithelial-to-mesenchymal transition (EMT) process promotes the generation of circulating tumor cells and their collective migration. Preclinical and clinical studies have documented intensive crosstalk between the gut microbiome, host organism, and immune system. According to the findings, polymorphic microbes might play diverse roles in tumorigenesis, cancer progression, and therapy response. Microbial imbalances and changes in the levels of bacterial metabolites and toxins promote cancer progression via EMT and angiogenesis. In contrast, a favorable microbial composition, together with microbiota-derived metabolites, such as short-chain fatty acids (SCFAs), can attenuate the processes of tumor initiation, disease progression, and the formation of distant metastases. In this review, we highlight the role of the intratumoral and gut microbiomes in cancer cell invasion, migration, and metastatic ability and outline the potential options for microbiota modulation. As shown in murine models, probiotics inhibited tumor development, reduced tumor volume, and suppressed angiogenesis and metastasis. Moreover, modulation of an unfavorable microbiome might improve efficacy and reduce treatment-related toxicities, bringing clinical benefit to patients with metastatic cancer.

Abstract
Human gut microbiota play an essential role in both healthy and diseased states of humans. In the past decade, the interactions between microorganisms and tumors have attracted much attention in the efforts to understand various features of the complex microbial communities, as well as the possible mechanisms through which the microbiota are involved in cancer prevention, carcinogenesis, and anti-cancer therapy. A large number of studies have indicated that microbial dysbiosis contributes to cancer susceptibility via multiple pathways. Further studies have suggested that the microbiota and their associated metabolites are not only closely related to carcinogenesis by inducing inflammation and immune dysregulation, which lead to genetic instability, but also interfere with the pharmacodynamics of anticancer agents. In this article, we mainly reviewed the influence of gut microbiota on cancers in the gastrointestinal (GI) tract (including esophageal, gastric, colorectal, liver, and pancreatic cancers) and the regulation of microbiota by diet, prebiotics, probiotics, synbiotics, antibiotics, or the Traditional Chinese Medicine. We also proposed some new strategies in the prevention and treatment of GI cancers that could be explored in the future. We hope that this review could provide a comprehensive overview of the studies on the interactions between the gut microbiota and GI cancers, which are likely to yield translational opportunities to reduce cancer morbidity and mortality by improving prevention, diagnosis, and treatment.

Abstract
Various signaling pathways exert critical roles in the epithelial to mesenchymal transition (EMT) and cancer stem cells (CSCs). The Wnt/beta-catenin, PI3K/PTEN/Akt/mTORC, Ras/Raf/MEK/ERK, hedgehog (Hh), Notch and TP53 pathways elicit essential regulatory influences on cancer initiation, EMT and progression. A common kinase involved in all these pathways is moon-lighting kinase glycogen synthase kinase-3 (GSK-3). These pathways are also regulated by micro-RNAs (miRs). TP53 and components of these pathways can regulate the expression of miRs. Targeting members of these pathways may improve cancer therapy in those malignancies that display their abnormal regulation. This review will discuss the interactions of the multi-functional GSK-3 enzyme in the Wnt/beta-catenin, PI3K/PTEN/Akt/mTORC, Ras/Raf/MEK/ERK, Hh, Notch and TP53 pathways. The regulation of these pathways by miRs and their effects on CSC generation, EMT, invasion and metastasis will be discussed.

Abstract
Signal exchange between intestinal epithelial cells, microbes and local immune cells is an important mechanism of intestinal homeostasis. Given that intestinal macrophages are in close proximity to both the intestinal epithelium and the microbiota, their pathologic interactions may result in epithelial damage. The present study demonstrates that co-incubation of murine macrophages with E. faecalis strains producing gelatinase (GelE) and serine protease (SprE) leads to resultant condition media (CM) capable of inducing reassembly of primary colonic epithelial cell monolayers. Following the conditioned media (CM) exposure, some epithelial cells are shed whereas adherent cells are observed to undergo dissolution of cell-cell junctions and morphologic transformation with actin cytoskeleton reorganization resulting in flattened and elongated shapes. These cells exhibit marked filamentous filopodia and lamellipodia formation. Cellular reorganization is not observed when epithelial monolayers are exposed to: CM from macrophages co-incubated with E. faecalis GelE/SprE-deficient mutants, CM from macrophages alone, or E. faecalis (GelE/SprE) alone. Flow cytometry analysis reveals increased expression of CD24 and CD44 in cells treated with macrophage/E. faecalis CM. This finding in combination with the appearance colony formation in matrigel demonstrate that the cells treated with macrophage/E. faecalis CM contain a higher proportion progenitor cells compared to untreated control. Taken together, these findings provide evidence for a triangulated molecular dialogue between E. faecalis, macrophages and colonic epithelial cells, which may have important implications for conditions in the gut that involve inflammation, injury or tumorigenesis.

Abstract
Understanding the role and mechanism of signaling pathways including Notch and Wnt in colorectal carcinogenesis is critical to the development of novel therapeutics. In the present study, we analyzed the cell proliferation, migration, G2/M percentage and the expression of molecules of signaling pathways in HCT-116 cells through the inhibition of Wnt and Notch pathways, and also investigated the effect of inhibitors of Wnt and Notch pathways on tumor growth in a transplantation tumor model. We observed that rDDK-1 (an inhibitor of the Wnt signaling pathway) and LY374973 (an inhibitor of the Notch signaling pathway) synergistically inhibited the proliferation, migration and G2/M percentage of HCT-116 cell lines, and could further synergistically inhibit the tumor volume and weight in the transplantation tumor model. In the cell line and the transplantation tumor model, rDDK-1 and LY374973 further synergistically inhibited the expression level of all detected Wnt and Notch pathway genes. Our results may pave the way for using inhibitors of Wnt and Notch signaling pathways together to treat colorectal cancer.

Abstract
S100P, a Ca2+ binding protein, has been shown to be overexpressed in various cancers. However, its functional character in lung cancer remains largely unknown. In this study, we show that S100P increases cancer migration, invasion and metastasis in lung cancer cells. Ectopic expression of S100P increases migration, invasion and EMT in less invasive CL1-0 lung cancer cells. Conversely, knockdown of S100P suppressed migration and invasion, and caused a reversion of EMT in highly invasive lung cancer cells. These effects were transduced by increasing the interaction of S100P with integrin α7, which activated focal adhesion kinase (FAK) and AKT. Blocking FAK significantly decreased S100P-induced migration by decreasing Src and AKT activation, whereas inhibiting AKT reduced S100P upregulation on ZEB1 expression. Further study has indicated that S100P knockdown prevents the spread of highly metastatic human lung cancer in animal models. This study therefore suggests that S100P represents a critical activator of lung cancer metastasis. Detection and targeted treatment of S100P-expressing cancer is an attractive therapeutic strategy in treating lung cancer.

Abstract
In recent decades, the chemokine receptor CXCR4 and its ligand CXCL12 have been extensively reported to be associated with tumorigenesis. In addition, Twist signaling induces the epithelial-mesenchymal transition (EMT) process in glioblastoma development. In the present study, in vitro assays were used to investigate the role of CXCR4 and Twist in human glioblastoma. We explored the impact of CXCR4 and Twist on human glioblastoma using in vitro protein and gene assays. We found the administration of CXCL12 upregulated the expression of p-ERK, p-AKT, Twist, N-cadherin, and MMP9 in U87 cells, whereas the increase of E-cadherin protein was affected. Subsequently, Twist activity and EMT signaling were directly influenced by PD98059 and LY294002. Most importantly, the genetic silencing of Twist inhibited CXCL12-induced EMT occurrence, including proliferation, migration, and tumor formation of U87 cells. In conclusion, CXCL12/CXCR4 pathway activates ERK and PI3K/AKT signaling to upregulate Twist pathway, leading to the progression of EMT in human glioblastoma. Our study creates a new stage for molecule-targeted therapy of human glioblastoma.

Abstract
In recent decades, the CXC chemokine receptor 7 (CCR7) [corrected] and its ligand CCL21 have been extensively reported to be associated with tumorigenesis. Meanwhile, Slug signaling induces the epithelial-mesenchymal transition (EMT) process in chondrosarcoma development. In the present study, we explored the functions of CCL21/CCR7 [corrected] in Slug-mediated EMT in the chondrosarcoma. We analyzed protein expression of CCR7 [corrected] and Slug in human chondrosarcoma samples. Effects of CCR7 [corrected] on chondrosarcoma cells were assessed by in vitro assays. Additionally, CCR7 [corrected] pathways were further investigated by pharmacological and genetic approaches. We found that the altered CCR7 [corrected] (81.7 %) and Slug (85.0 %) expression in human chondrosarcoma tissues were significantly associated with grade, recurrence, and 5-year overall survival. According to in vitro assays, CCL21 stimulation induced the expression of phosph-ERK, phosph-AKT, Slug and N-cadherin in SW1353 cells, while the expression of E-cadherin was down-regulated. Furthermore, Slug signaling modulated E- to N-cadherin switch, which was influenced by the kinase inhibitor PD98059 and LY294002. In addition, the genetic silencing of Slug inhibited the capacity of migration and invasion of SW1353 cells. In conclusion, CCL21/CCR7 [corrected] pathway activates ERK and PI3K/AKT signallings to up-regulate Slug pathway, leading to the occurrence of EMT process in human chondrosarcoma. This study lays a new foundation for molecule-targeted therapy of human chondrosarcoma.
