Summary: This study found that the expression of R345W-Fibulin-3 mutation alters the size and cargo of extracellular vesicles (EVs), which are sufficient to enhance cell migration in a TGF beta-dependent manner. These findings suggest that EV-bound TGF beta plays a critical role in inducing epithelial-mesenchymal transition (EMT) in retinal pigment epithelial (RPE) cells.

Summary: This study successfully induced EMT in RPE cells through prolonged low-density culture, and found that the combination of the ROCK inhibitor Y27632 and the TGF-beta receptor inhibitor RepSox effectively suppressed and reversed the EMT process, maintaining the morphology and function of RPE cells and the retina. This combined therapy could be a new strategy for treating proliferative retinal diseases involving EMT of RPE cells.

Summary: Lung cancer is a major global cause of cancer-related deaths due to a lack of early diagnostics and effective treatments. In a study, EVs derived from A549 lung adenocarcinoma cells were transferred to healthy human bronchial epithelial cells. It was found that the EVs carry oncogenic proteins involved in promoting tumor growth and invasion through the EMT pathway regulated by beta-catenin. This study suggests that cancer-cell-derived EVs can induce tumorigenesis in neighboring healthy cells.

Summary: In this study, it was found that DGM could inhibit TGF-beta 1-induced EMT in A549 cells and bleomycin-induced pulmonary fibrosis in rats. Furthermore, DGM treatment improved lung function, reduced lung inflammation and fibrosis, and decreased collagen deposition.

Summary: Epithelial-mesenchymal transition (EMT) plays a crucial role in cancer progression, associated with invasion, metastasis, generation of tumor stem cells, and resistance to therapy. Transforming growth factor (TGF)-beta acts as a key mediator in the EMT process, initiating and maintaining EMT through signaling pathways and transcription factors.

Summary: Drug resistance in oral cancer is a major issue due to therapeutic failure, with ncRNAs playing a crucial role in regulating gene expression and intercellular communication related to drug resistance. These ncRNAs could potentially serve as therapeutic targets and biomarkers for cancer diagnosis.

Summary: This study demonstrates that PM2.5 exposure can directly induce cardiac fibrosis by promoting collagen deposition through TGF-beta-containing sEV. These findings reveal the underlying mechanism of PM2.5-induced cardiotoxicity.

Summary: Organ fibrosis is a process of excessive extracellular matrix deposition which can lead to vital organ failure. Despite the hypothesis that epithelial-mesenchymal transition (EMT) may be a key mechanism, the underlying mechanisms of fibrosis are still largely unknown.

Summary: This study examined the interplay between seminal extracellular vesicles (sEVs) and transforming growth factor beta (TGF-beta) in the male reproductive tract. The results showed that sEVs in the seminal plasma transport active forms of TGF-beta and that ejaculated spermatozoa express TGF-beta both inside and outside, possibly associated with membrane-bound sEVs.

Summary: Metabolic changes in the tumor microenvironment play a critical role in cancer by affecting signaling pathways that control cellular metabolism. The deregulation of cancer metabolism is closely related to oxidative stress control and the involvement of cytokines like transforming growth factor beta (TGF-beta) in tumorigenesis and cancer progression. The crosstalk between TGF-beta and oxidative stress contributes significantly to tumorigenesis and cancer invasiveness by affecting redox imbalance and cellular metabolism.

Summary: Immune-checkpoint inhibitors are effective in treating lung cancer, but there is a need for better predictive biomarkers to identify patients who will benefit. This study found that high levels of TGF-beta in extracellular vesicles before treatment were a better predictor of response to ICIs and survival compared to circulating TGF-beta and tissue PD-L1.

Summary: Tumor-derived extracellular vesicles (tdEVs) have great potential as biomarkers for liquid biopsy-based cancer diagnostics due to the specific membrane proteins they express. This study developed an indium-tin-oxide (ITO) sensor integrated microfluidic device for the sensitive detection and quantification of tdEVs. The device successfully captured tdEVs on specific antibody modified ITO surfaces and showed excellent linear response in the clinically relevant tdEVs-concentration range for pancreatic cystic neoplasms. This system holds promise for liquid biopsy-based cancer prognostics and diagnostics.

Summary: In this study, the researchers found that VGLL3 promotes epithelial-to-mesenchymal transition (EMT)-like cell motility by inducing HMGA2 expression and accelerates cancer progression. High levels of VGLL3 expression were shown to have a positive correlation with poor prognosis in various human cancers.
