Cell migration and invasion are two essential processes during cancer metastasis. Increasing evidence has shown that the Piezo1 channel is involved in mediating cell migration and invasion in some types of cancers. However, the role of Piezo1 in the breast cancer and its underlying mechanisms have not been clarified yet. Here, we show that Piezo1 is high-expressed in breast cancer cell (BCC) lines, despite its complex expression in clinical patient database. Piezo1 knockdown (Piezo1-KD) promotes unconfined BCC migration, but impedes confined cell migration. Piezo1 may mediate BCC migration through the balances of cell adhesion, cell stiffness, and contractility. Furthermore, Piezo1-KD inhibits BCC invasion by impairing the invadopodium formation and suppressing the expression of metalloproteinases (MMPs) as well. However, the proliferation and cell cycle of BCCs are not significantly affected by Piezo1. Our study highlights a crucial role of Piezo1 in regulating migration and invasion of BCCs, indicating Piezo1 channel might be a new prognostic and therapeutic target in BCCs.

Circular RNAs (circRNAs), along with their pathogenic property in non-small cell lung cancer (NSCLC), require comprehensive analyses and explanations. The study is established with the purpose to elucidate the potential molecular mechanism of circATP9A in NSCLC. CircATP9A and microRNA (miR)-582-3p were evaluated by real-time quantitative polymerase chain reaction, and ribosomal protein large P0 (RPLP0), cleaved caspase-3, cleaved Ki-67, epithelial-to-mesenchymal transition (EMT)-associated proteins (N-cadherin and E-cadherin), and core proteins of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway were by Western blot.

Purpose: The purpose of this study is to investigate the role of Secretogranin III (Scg3) in the pathogenesis of intraocular neovascular diseases and assess its potential as a therapeutic target for novel treatment strategies.
Methods: A literature review was conducted to examine the expression of Scg3 in intraocular neovascular diseases. We reviewed studies on the interaction of Scg3 with its homologous receptors and its effect on endothelial cell proliferation, migration, and vascular permeability-key processes involved in angiogenesis and neovascularization.

Nonylphenol (NP) is a common environmental contaminant and endocrine disruptor. Our previous research demonstrated that NP could promote the proliferation and epithelial-mesenchymal transition (EMT) of colorectal cancer (CRC) cells; however, the specific mechanism remains unclear. miRNA sequencing revealed that NP upregulated the expression levels of microRNA(miR)-151a-3p in CRC.

Purpose: Intrahepatic cholangiocarcinoma (ICC) is a common primary hepatic tumors with a 5-year survival rate of less than 20%. Therefore, it is crucial to elucidate the molecular mechanisms of ICC. Recently, the advance of high-throughput chromosome conformation capture (Hi-C) technology help us look insight into the three-dimensional (3D) genome structure variation during tumorigenesis.
