Summary: The study induced EMT in human stem cell-derived RPE monolayers using two model systems and found that dysregulated proteocollagenolytic enzymatic dissociation and co-treatment with TGF-beta and TNF-alpha were key factors in promoting EMT. It also identified widespread dysregulation of axon guidance molecules during RPE-EMT progression, suggesting potential therapeutic targets for retinal diseases.

Summary: The tumor microenvironment plays a crucial role in the formation and development of tumors. Cytokines, such as TGF-beta and TNF-alpha, have different effects on tumor growth, metastasis, and prognosis at different stages. Inhibiting TGF-beta can promote tumor formation, while TGF-beta can contribute to tumor malignancy. TNF-alpha, initially identified as a natural immune serum mediator for tumor hemorrhagic necrosis, has broad biological activities and can be targeted for immune diseases and tumors. However, there is limited research on the interaction between these two cytokines in the tumor microenvironment.

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: Cancer-associated fibroblasts (CAFs) play a crucial role in breast cancer initiation, metastasis, and invasion. This study investigated the requirement of autophagy and FAP-alpha in breast cancer cell invasion and metastasis, finding that both are necessary. Targeting autophagy or FAP-alpha individually may be a potential approach to improve the prognosis of human breast cancer.

Summary: This study demonstrates that 2,3,5,6-Tetramethylpyrazine (TMP) can suppress the EMT program in colon cancer cells by regulating MnSOD and related proteins, and inhibit the proliferation, migration, and invasion of tumor cells.

Summary: Epithelial to Mesenchymal Transition (EMT) is a process in which epithelial cells transition to a motile and invasive mesenchymal phenotype. The EMT process is associated with an increase in fibronectin (FN) assembly and the localization of Transforming Growth Factor-beta 1 (TGF-beta 1) to FN fibrils. This study investigated the spatial gradients of EMT and FN fibrillogenesis in mammary epithelial cells cultured on square micropatterns in response to TGF-beta 1. The results showed that increasing TGF-beta 1 concentration induced a spatial gradient of both E-Cadherin and FN fibrils, and inhibition of FN fibril assembly globally reduced both E-Cadherin-containing adherens junctions and FN fibrillogenesis, but did not eliminate the spatial gradients.

Summary: TGF-beta induces metabolic reprogramming in epithelial cells during EMT, affecting glycolysis, TCA cycle, glutaminolysis, choline metabolism, cellular redox state, and other pathways. Inhibiting choline kinase alpha with a kinase inhibitor can attenuate TGF-beta-induced changes associated with EMT.

Summary: Metastasis of tumor cells to vital organs is a major cause of cancer death, with inflammatory signals influencing an identity switch in tumor cells. Syndecan-1 plays a crucial role in regulating this switch, with nuclear localization of SDC1 associated with the regulation of EMT.

Summary: Somatic cell reprogramming proceeds through a series of events to generate induced pluripotent stem cells (iPSCs). In this study, the researchers found that the downregulation of Osr2 is crucial for efficient reprogramming by using a cell-based model. Osr2 acts as a novel EMT regulator and its downregulation diminishes TGF-beta signaling and activates Wnt signaling, promoting MET and acquiring pluripotency.

Summary: This study demonstrates the critical role of PIEZO1 signaling in radiation-induced epithelial-mesenchymal transition (EMT) by forming a positive feedback loop with TGF-beta 1. Activation of PIEZO1 can upregulate TGF-beta 1 expression and promote EMT through the Ca2+/HIF-1 alpha signaling pathway, while knockdown of PIEZO1 or HIF-1 alpha partially reverses radiation-induced EMT. Additionally, the expression of PIEZO1 is regulated by the transcription factor C/EBP beta, which further influences the EMT process in response to radiation and TGF-beta 1.

Summary: Bixin, a natural compound isolated from Bixa Orellana seeds, has shown potential in treating asthma by suppressing allergic airway inflammation, reversing glucocorticoids resistance, and alleviating airway remodeling and hyperresponsiveness. It functions as an antagonist of PI3K/Akt signaling, offering a novel strategy for asthma treatment.
