TLDR
The functional requirement of EMT and/or MET during the individual steps of tumor metastasis is reviewed and the potential of targeting this program when treating metastatic diseases is discussed.
Abstract
Tumor metastasis is a multistep process by which tumor cells disseminate from their primary site and form secondary tumors at a distant site. Metastasis occurs through a series of steps: local invasion, intravasation, transport, extravasation, and colonization. A developmental program termed epithelial-mesenchymal transition (EMT) has been shown to play a critical role in promoting metastasis in epithelium-derived carcinoma. Recent experimental and clinical studies have improved our knowledge of this dynamic program and implicated EMT and its reverse program, mesenchymal-epithelial transition (MET), in the metastatic process. Here, we review the functional requirement of EMT and/or MET during the individual steps of tumor metastasis and discuss the potential of targeting this program when treating metastatic diseases.

Progress of Anti-Cancer Function of Solanine

TL;DR: Wang et al. as mentioned in this paper reviewed the anti-cancer effects of solanine and its mechanism and showed that it plays a role in pre-vention and treatment of many diseases, including its anti-tumor effect.

TL;DR: Together, the findings present a more comprehensive picture of residual tumor cells surviving targeted therapy, and suggest possible therapeutic strategies for targeting residual disease that gives rise to cancer recurrence.

Value of biomarkers in epithelial-mesenchymal transition models of liver cancer under different interventions: a meta-analysis.

TL;DR: Wang et al. as mentioned in this paper conducted a meta-analysis to evaluate the effectiveness of crucial biomarkers in HepG2 cells during epithelial-mesenchymal transformation induced by multiple interventions.

Уровень онкофетальных белков в патологических тканях больных раком желудка

TL;DR: The content of oncoprotein markers in tissues of the peritoneum and omentum is one of the factors associated with metastatic characteristics, and CA-19.9 level can serve as an informative laboratory test for the predictive assessment of the further disease development.

Gene expression patterns of breast carcinomas distinguish tumor subclasses with clinical implications

TL;DR: Survival analyses on a subcohort of patients with locally advanced breast cancer uniformly treated in a prospective study showed significantly different outcomes for the patients belonging to the various groups, including a poor prognosis for the basal-like subtype and a significant difference in outcome for the two estrogen receptor-positive groups.

TL;DR: The ability to prospectively identify tumorigenic cancer cells will facilitate the elucidation of pathways that regulate their growth and survival and strategies designed to target this population may lead to more effective therapies.

Epithelial-Mesenchymal Transitions in Development and Disease

TL;DR: The mesenchymal state is associated with the capacity of cells to migrate to distant organs and maintain stemness, allowing their subsequent differentiation into multiple cell types during development and the initiation of metastasis.

The basics of epithelial-mesenchymal transition

TL;DR: Processes similar to the EMTs associated with embryo implantation, embryogenesis, and organ development are appropriated and subverted by chronically inflamed tissues and neoplasias and the identification of the signaling pathways that lead to activation of EMT programs during these disease processes is providing new insights into the plasticity of cellular phenotypes.
