Epithelial to mesenchymal phenotype transition is a common phenomenon during embryonic development, wound healing, and tumor metastasis. This transition involves cellular changes in cytoskeleton architecture and protein expression. Specifically, this highly regulated biological event plays several important roles during craniofacial development. This review focuses on the regulation of epitheli...
Previous studies have suggested that breast cancer stem cells (BCSCs) mediate metastasis, are resistant to radiation and chemotherapy, and contribute to relapse. Although several BCSC markers have been described, it is unclear whether these markers identify the same or independent BCSCs. Here, we show that BCSCs exist in distinct mesenchymal-like (epithelial-mesenchymal transition [EMT]) and ep...
We report that the activity of glycogen synthase kinase-3 (GSK-3) is necessary for the maintenance of the epithelial architecture. Pharmacological inhibition of its activity or reducing its expression using small interfering RNAs in normal breast and skin epithelial cells results in a reduction of E-cadherin expression and a more mesenchymal morphology, both of which are features associated wit...
During heart morphogenesis, epicardial cells undergo epithelial-mesenchymal transition giving origin to a population of epicardially derived cells that play a crucial role in the development of most cardiac cell lineages. Considering the hypothesis that epithelial-mesenchymal transition of epicardial mesothelium can generate cardiac primitive cells in the adult heart, we have examined in vivo a...
β-catenin is a master regulator in the cellular biology of development and neoplasia. Its dysregulation is implicated as a driver of colorectal carcinogenesis and the epithelial-mesenchymal transition in other cancers. Nuclear β-catenin staining is a poor prognostic sign in synovial sarcoma, the most common soft-tissue sarcoma in adolescents and young adults. We show through genetic experiments...
Unraveling the genetic programs that drive -metastasis may offer insights into how to limit or prevent this deadly aspect of cancer progression. Our recent studies indicate that tumor cell metastasis involves the activity of the transcription factor, Twist, which regulates epithelial-mesenchymal transition and early embryonic morphogenesis. Here, we review the Twist signaling pathway during nor...
Apocrine cystomatosis, also called epitrichial sweat gland is a non-neoplastic condition characterised by multiple dilated cysts of origin. Histopathologically, these comprise two layers cells: an inner layer glandular epithelial cells and outer myoepithelial cells. A case apocrine cystomatosis was admitted to local hospital. The microscopic investigation revealed that some enlarged show...
IKBKE is increased in several types of cancers and is associated with tumour malignancy. In this study, we confirmed that IKBKE promoted glioma proliferation, migration and invasion in vitro. Then, we further discovered that IKBKE increased Yes-associated protein 1 (YAP1) and TEA domain family member 2 (TEAD2), two important Hippo pathway downstream factors, to induce an epithelial-mesenchymal ...
RBP2 has been found to actively participate in cancer progression. It inhibits the senescence of cancer cells, mediates cancer cell proliferation and promotes cancer metastasis. It is also essential to drug tolerance. However, the effects of RBP2 on epithelial-mesenchymal transition are still unknown. In this study, we analyzed the effects of RBP2 on epithelial-mesenchymal transition in non-sma...
Cyclin dependent kinase-3 (Cdk3) is a positive regulator of the G1 mammalian cell cycle phase. Cdk3 is involved in cancer progression, but very little is known about its mechanism in cancer development and progression. Herein, we found that Cdk3 increased colorectal cancer metastasis through promoting epithelial-mesenchymal transition (EMT) shift. Cdk3 was found to highly express in metastatic ...
