Summary: Metaplastic breast carcinoma (MBC) is a rare triple negative invasive cancer with poor prognosis. The resistance mechanisms of MBC may involve epithelial-mesenchymal transition (EMT) and immune response, distinguishing it from other types of breast cancer.

Summary: This review summarizes the role of EMT in the pathogenesis of Metaplastic Breast Carcinoma (MBC) and Phyllodes tumors (PTs), and suggests several anti-EMT targeting strategies as promising therapeutic approaches for patients suffering from these aggressive neoplasms.

Summary: The study found that cytoplasmic pEZH2 T367 is significantly upregulated in squamous subtypes compared to mesenchymal and spindle subtypes. The expression and subcellular localization of cytoplasmic pEZH2 T367 may be useful for distinguishing metaplastic carcinoma subtypes.

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: The study revealed that the overexpression of CHN1 is associated with lymph node metastasis and low survival rates in cervical carcinoma patients. CHN1 overexpression promoted cell proliferation, migration, and invasion by inducing EMT-related transcription factors. Furthermore, in vitro experiments showed that CHN1 overexpression activated the Akt/GSK-3 beta/Snail signaling pathway.

Summary: Metaplastic breast cancer (MpBC) is a rare aggressive malignancy with poor prognosis. The relationships between clinical and pathological features, treatment approach, and outcomes of MpBC remain underexplored. In this review article, existing data on MpBC regarding clinical, pathological and genomic features, management, and outcomes are synthesized, and potential targets for future clinical trials are identified.

Summary: The study reveals that aging ECM can drive normal mammary epithelial cells to a more invasive and cancer-like phenotype, and enhance motility and invasiveness in breast cancer cells. Different responses of cells to young and aged ECMs may lead to the identification of new targets for cancer treatment and prevention.

Summary: Metaplastic breast carcinomas are rare tumors with poor prognosis, characterized by high frequency of TP53 and TERT promoter mutations, as well as MYC amplifications. Relapse/progression samples are particularly enriched for MYC amplification.

Summary: The study revealed that partial EMT may be involved in the development of pulmonary fibrosis diseases, with Snail playing a critical role in the process. The process of EMT in epithelial cells promoted the differentiation of lung myofibroblasts, and this epithelial-mesenchymal crosstalk was mainly controlled by Snail.

Summary: This study analyzed the clinical outcomes, survival status, and genomic profiles of patients with metaplastic breast cancer (MpBC) who received neoadjuvant therapy. The results showed that MpBC patients had a lower response rate to the therapy, shorter survival time, and distinct genetic characteristics compared to non-metaplastic triple-negative breast cancer (TNBC) patients. Furthermore, some non-MpTNBC patients exhibited similar gene expression profiles and treatment responses to MpBC.

Summary: In this study, the transcription factor Snail is found to play a role in maintaining the stemness of epidermal keratinocytes in cutaneous squamous cell carcinoma (cSCC) models through the secretion of Mindin protein and activation of the Src-STAT3 pathway. Disruption of this signaling module attenuates tumorigenesis in human cSCC.

Summary: In this study, it was found that PKD1 is correlated with metastasis and poor prognosis in SACC patients. Inhibition of PKD1 attenuated proliferation, migration, invasion, and EMT of SACC cells, while kinase active PKD1 promoted cell migration. The mechanism involves PKD1 regulating Snail protein stability to impact SACC metastasis.

Summary: SPOCK1 is found to be upregulated in ccRCC tissues and is associated with advanced clinical stages and metastasis. Knockdown and overexpression of SPOCK1 in ccRCC cells affect cell clonogenic ability, migration/invasion ability, and tumor growth and invasion in vitro and in vivo. The mechanism involves the activation of the Snail/Slug-MMP-2 axis to promote EMT and cell motility.

Summary: The study reveals that EMT can change the mechanical properties of skin epithelial cells in a cell-cycle dependent manner. Additionally, EMT can boost cellular proliferation and result in changes in the actin cortex. These changes are primarily dependent on the transcription factor snail, which is upregulated during EMT.
