- Phase separation orchestrates cancer signaling. ACA-28, a novel ERK signaling modulator with anti-cancer activity, regulates stress granules.
抄録
<p>Stress granule (SG) is a conserved cellular strategy that copes with stress-related damage and promotes cell survival. SGs form through a process of liquid-liquid phase separation (LLPS). Cellular signaling also employs SG assembly as a mechanism for controlling cell survival and cell death by spatial compartmentalization of signal-transducing factors, thus indicating that SGs constitute signaling hubs that can rewire cancer signal transduction. Recently, SGs have attracted strong attention as a promising target for cancer treatment because of their involvement in various aspects of cancer progression, ranging from cancer formation, and metastasis as well as drug resistance. Here, I will report our discoveries of the role of SGs as a safeguard to prevent excess hyperactivation of PKC/MAPK signaling as well as a novel anti-cancer compound ACA-28 with a unique property. ACA-28 was shown to inhibit the proliferation of several cancer cell lines with high ERK, including melanoma and pancreatic cancer. Importantly, ACA-28 was shown to induce cancer cell-specific apoptosis and impact SG formation by stimulating ERK activity. We will discuss fundamental aspects of LLPS as a new paradigm for cancer biology and then focus on recent advances in the role of SGs in cancer signaling, especially therapeutic strategies targeting SGs.</p>
