Biological functions and molecular interactions of Wnt/β-catenin in breast cancer: Revisiting signaling networks.

Changes in lifestyle such as physical activity and eating habits have been one of the main reasons for development of various diseases in modern world, especially cancer. However, role of genetic factors in initiation of cancer cannot be ignored and Wnt/β-catenin signaling is such factor that can affect tumor progression. Breast tumor is the most malignant tumor in females and it causes high mortality and morbidity around the world.

Long non-coding RNA/epithelial-mesenchymal transition axis in human cancers: Tumorigenesis, chemoresistance, and radioresistance.

Epithelial-to-mesenchymal transition (EMT) is a process that involves the transformation of polarized epithelial cells to attain a mesenchymal phenotype that presents an elevated migratory potential, invasiveness, and antiapoptotic properties. Many studies have demonstrated that EMT is a prominent event that is associated with embryogenesis, tumor progression, metastasis, and therapeutic resistance. The EMT process is driven by key transcription factors (such as Snail, Twist, ZEB, and TGF-β) and several long non-coding RNAs (lncRNAs) in many non-pathological as well as pathological conditions.
