Summary: The study analyzed the expression of the miR-200 family as EMT markers and their target genes in colorectal carcinoma. It found partial EMT at the invasive tumor front and partial MET in metastases based on miR-200 family and its target genes expression.

Summary: Objective of this study was to investigate the effect of amygdalin, an active ingredient in bitter almonds, on TGF-beta-induced EMT in bronchial epithelial cells and elucidate the underlying mechanisms. The results showed that amygdalin treatment relieved airway wall remodeling and decreased the expressions of EMT markers. Furthermore, amygdalin inhibited TGF-beta-induced EMT through regulating the expression of HPSE.

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: Using human colon cancer DLD-1 cells, the study engineered a cell line with inducible Snail expression and found that partial EMT induced by Snail overexpression in DLD-1 cells leads to chemoresistance, increased tumor growth, and decreased apoptosis, highlighting the importance of bioavailable Snail in determining the phenotypic outcome.

Summary: This study demonstrated that TGF-beta 2 induces autophagy flux during EMT progression of LECs, with autophagy activation enhancing fibrogenic responses and cell migration, while autophagy inhibition alleviates EMT markers and cell migration. Additionally, modulation of Smad signaling by autophagy was observed, and ATG7-silenced LECs showed antifibrosis effect induced by TGF-beta 2. Overall, intervention/inhibition of autophagy could attenuate TGF-beta 2-induced EMT in LECs, providing insights for preventing and treating fibrotic cataracts and other fibrotic diseases.

Summary: Research shows that the transcription factor KLF4 can delay the onset of EMT by suppressing multiple EMT-TFs and promote a phenotypic shift towards a more epithelial state. KLF4 can also strengthen its influence on modulating EMT dynamics by inhibiting cell-state transitions at the epigenetic level.

Summary: The endometrium undergoes repeated changes during the menstrual cycle, and chronic endometritis can lead to implantation failure and miscarriage. In this study, the effects of inflammatory cytokines, hypoxia-inducible factor (HIF), and inflammation on endometrial epithelial cells were investigated. The results showed that pro-inflammatory factors and hypoxia activated HIF-1 and promoted epithelial-mesenchymal transition (EMT) in endometrial epithelial cells.

Summary: The study demonstrates that breast cancer brain metastasis cells undergo epithelial-to-mesenchymal transition (EMT) when infiltrating the brain parenchyma, and removing these infiltrated tumor cells can improve surgical efficacy, providing new avenues for patient treatment.

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: The liver is the most common site for colorectal cancer (CRC) metastasis, with colorectal liver metastasis (CLM) having a poor prognosis. Tumor-associated macrophages (TAMs) play a role in promoting epithelial-to-mesenchymal transition (EMT) through the TGF-beta signaling pathway, contributing to CLM development. However, the exact mechanism of the interaction between TAMs and EMT is still poorly understood.

Summary: Optic nerve head cupping, a feature of glaucoma, is associated with extracellular matrix remodeling and lamina cribrosa fibrosis. Peripapillary atrophy is common in glaucoma and involves the loss of retinal pigment epithelium adjacent to the optic nerve head. Under pro-fibrotic conditions, epithelial cells can undergo epithelial-to-mesenchymal transition and contribute to extracellular matrix fibrosis. This study investigates the role of this process in glaucoma and peripapillary atrophy, demonstrating the presence of retinal pigment epithelium cells in glaucomatous optic nerve heads and the potential of these cells to differentiate into fibroblast-like cells.
