TOE1 deadenylase inhibits gastric cancer cell proliferation by regulating cell cycle progression.

TOE1, also known as hCaf1z, belongs to the DEDD superfamily of deadenylases and a newly identified isoenzyme of hCaf1 deadenylases. Previous research has demonstrated that TOE1 has deadenylase activity, which can catalyze the degradation of poly(A) substrates and interact with hCcr4d to form the unconventional human Ccr4-Caf1 deadenylase complex. Our recent research indicates that hCaf1a and hCaf1b isoenzymes, highly expressed in gastric cancer, promote gastric cancer cell proliferation and tumorigenicity via modulating cell cycle progression.

Membrane to cortex attachment determines different mechanical phenotypes in LGR5+ and LGR5- colorectal cancer cells.

Colorectal cancer (CRC) tumors are composed of heterogeneous and plastic cell populations, including a pool of cancer stem cells that express LGR5. Whether these distinct cell populations display different mechanical properties, and how these properties might contribute to metastasis is poorly understood. Using CRC patient derived organoids (PDOs), we find that compared to LGR5- cells, LGR5+ cancer stem cells are stiffer, adhere better to the extracellular matrix (ECM), move slower both as single cells and clusters, display higher nuclear YAP, show a higher survival rate in response to mechanical confinement, and form larger transendothelial gaps.
