Abstract
Biomolecular condensates or membraneless organelles (MLOs) formed by liquid-liquid phase separation (LLPS) divide intracellular spaces into discrete compartments for specific functions. Dysregulation of LLPS or aberrant phase transition that disturbs the formation or material states of MLOs is closely correlated with neurodegeneration, tumorigenesis, and many other pathological processes. Herein, we summarize the recent progress in development of methods to monitor phase separation and we discuss the biogenesis and function of MLOs formed through phase separation. We then present emerging proof-of-concept examples regarding the disruption of phase separation homeostasis in a diverse array of clinical conditions including neurodegenerative disorders, hearing loss, cancers, and immunological diseases. Finally, we describe the emerging discovery of chemical modulators of phase separation.

Abstract
Huntington's disease (HD) is a fatal neurodegenerative disease associated with autophagy disorder and mitochondrial dysfunction. Here, we identified therapeutic potential of perillaldehyde (PAE), a monoterpene compound obtained from Perilla frutescens (L.) Britt., in the Caenorhabditis elegans (C. elegans) model of HD, which included lifespan extension, healthspan improvement, decrease in polyglutamine (polyQ) aggregation, and preservation of mitochondrial network. Further analyses indicated that PAE was able to induce autophagy and mitochondrial unfolded protein reaction (UPRmt) activation and positively regulated expression of associated genes. In lgg-1 RNAi C. elegans or C. elegans with UPRmt-related genes knockdown, the effects of PAE treatment on polyQ aggregation or rescue polyQ-induced toxicity were attenuated, suggesting that its neuroprotective activity depended on autophagy and UPRmt. Moreover, we found that pharmacological and genetic activation of UPRmt generally protected C. elegans from polyQ-induced cytotoxicity. Finally, PAE promoted serotonin synthesis by upregulating expression of TPH-1, and serotonin synthesis and neurosecretion were required for PAE-mediated UPRmt activation and its neuroprotective activity. In conclusion, PAE is a potential therapy for polyQ-related diseases including HD, which is dependent on autophagy and cell-non-autonomous UPRmt activation.

Discovery of SQSTM1/p62-dependent P-bodies that regulate the NLRP3 inflammasome. Cell Rep 2024; 43:113935.

Abstract
Autophagy and ribonucleoprotein granules, such as P-bodies (PBs) and stress granules, represent vital stress responses to maintain cellular homeostasis. SQSTM1/p62 phase-separated droplets are known to play critical roles in selective autophagy; however, it is unknown whether p62 can exist as another form in addition to its autophagic droplets. Here, we found that, under stress conditions, including proteotoxicity, endotoxicity, and oxidation, autophagic p62 droplets are transformed to a type of enlarged PBs, termed p62-dependent P-bodies (pd-PBs). p62 phase separation is essential for the nucleation of pd-PBs. Mechanistically, pd-PBs are triggered by enhanced p62 droplet formation upon stress stimulation through the interactions between p62 and DDX6, a DEAD-box ATPase. Functionally, pd-PBs recruit the NLRP3 inflammasome adaptor ASC to assemble the NLRP3 inflammasome and induce inflammation-associated cytotoxicity. Our study shows that p62 droplet-to-PB transformation acts as a stress response to activate the NLRP3 inflammasome process, suggesting that persistent pd-PBs lead to NLRP3-dependent inflammation toxicity.

Abstract
Cells contain a myriad of membraneless ribonucleoprotein (RNP) condensates with distinct compositions of proteins and RNAs. RNP condensates participate in different cellular activities, including RNA storage, mRNA translation or decay, stress response, etc. RNP condensates are assembled via liquid-liquid phase separation (LLPS) driven by multivalent interactions. Transition of RNP condensates into bodies with abnormal material properties, such as solid-like amyloid structures, is associated with the pathogenesis of various diseases. In this review, we focus on how RNAs regulate multiple aspects of RNP condensates, such as dynamic assembly and/or disassembly and biophysical properties. RNA properties - including concentration, sequence, length and structure - also determine the phase behaviors of RNP condensates. RNA is also involved in specifying autophagic degradation of RNP condensates. Unraveling the role of RNA in RNPs provides novel insights into pathological accumulation of RNPs in various diseases. This new understanding can potentially be harnessed to develop therapeutic strategies.

Abstract
The phenomenon of phase separation is quite common in cells, and it is involved in multiple processes of life activities. However, the current research on the correlation between protein modifications and phase separation and the interference with the tendency of phase separation has some limitations. Here we focus on several post-translational modifications of proteins, including protein phosphorylation modification at multiple sites, methylation modification, acetylation modification, ubiquitination modification, SUMOylation modification, etc., which regulate the formation of phase separation and the stability of phase separation structure through multivalent interactions. This regulatory role is closely related to the development of neurodegenerative diseases, tumors, viral infections, and other diseases, and also plays essential functions in environmental stress, DNA damage repair, transcriptional regulation, signal transduction, and cell homeostasis of living organisms, which provides an idea to explore the interaction between novel protein post-translational modifications and phase separation.

Abstract
Phase transitions (PT) of biomolecules are heavily involved in neurodegenerative disorders. Almost all previous studies were focusing on the PT of misfolded proteins whereas RNA molecules containing expanded repeats such as the CAG repeats are also able to undergo PT in vitro, a process called RNA gelation. Meanwhile, the expanded CAG repeat (eCAGr) RNA forms condensates that are largely observed only in the nuclei and exhibit liquid-like properties without obvious gelation. Thus, whether eCAGr RNA gelation occurs in cells and what function it is involved in remained elusive. We recently discovered that eCAGr RNA forms solid-like RNA gels in the cytoplasm, but they are rapidly cleared by the lysosomes via an autophagy-independent but LAMP2C-depdent pathway, making their presence in the cytoplasm difficult to be observed. We further revealed that these RNA gels sequester EEF2 in the cells and thus suppress global protein synthesis. In vivo expression of eCAGr RNA alone without detectable protein expression in the mouse model led to neurodegeneration-relevant electrophysiological and behavioral phenotypes, demonstrating its possible pathogenic roles.

Abstract
CAG-repeat expansions underlie fatal neurodegenerative disorders. In a lodestar study published in a recent issue of Nature, Sun et al.1 identify a writer and eraser of N1-methyladenosine (m1A) modifications of CAG-repeat RNA. They establish that m1A modifications in CAG-repeat expanded RNA promote neurodegeneration and aberrant phase transitions of TDP-43. These findings suggest therapeutic strategies for CAG-repeat expansion disorders.

Abstract
Our understanding of stress granule (SG) biology has deepened considerably in recent years, and with this, increased understanding of links has been made between SGs and numerous neurodegenerative diseases. One of the proposed mechanisms by which SGs and any associated protein aggregates may become pathological is based upon defects in their autophagic clearance, and so the precise processes governing the degradation of SGs are important to understand. Mutations and disease-associated variants implicated in amyotrophic lateral sclerosis, Huntington's disease, Parkinson's disease and frontotemporal lobar dementia compromise autophagy, whilst autophagy-inhibiting drugs or knockdown of essential autophagy proteins result in the persistence of SGs. In this review, we will consider the current knowledge regarding the autophagy of SG.

Abstract
Increased mitochondrial damage plays a critical role in many neurodegeneration-related diseases such as Parkinson's disease (PD) and Down syndrome (DS). Thus, enhancement of mitochondrial degradation by small molecule compounds may provide promising new strategies to tackle these diseases. Here, we explored the strategy to induce clearance of mitochondria by targeting them to the autophagy machinery by autophagy-tethering compounds (ATTECs). We provided the proof-of-concept evidence demonstrating that the bifunctional compound (mT1) binding to both the outer mitochondrial membrane protein TSPO and the autophagosome protein LC3B simultaneously may enhance the engulfment of damaged mitochondria by autophagosomes and subsequent autophagic degradation of them. In addition, preliminary experiments suggest that mT1 attenuated disease-relevant phenotypes in both a PD cellular model and a DS organoid model. Taken together, we demonstrate the possibility of degrading mitochondria by bifunctional ATTECs, which confirms the capability of degrading organelles by ATTECs and provides potential new strategies in the intervention of mitochondria-related disorders.
