Proteostasis regulation of GABA_ARs involves subunit folding within the endoplasmic reticulum, assembling into heteropentamers, receptor trafficking to the cell surface, and degradation of terminally misfolded subunits. As GABA_ARs are surface proteins, their trafficking to the plasma membrane is critical for proper receptor function. Thus, variants in the genes encoding GABA_ARs that disrupt proteostasis result in various neurodevelopmental disorders, ranging from intellectual disability to idiopathic generalized epilepsy. This review summarizes recent progress about how the proteostasis network regulates protein folding, assembly, degradation, trafficking, and synaptic clustering of GABA_ARs.

In gastrointestinal tumors the Formyl peptide receptor 1 (FPR1) stimulates an inflammation resolution response able to restrain cancer angiogenesis and growth. A preceding inflammatory signal is necessary for the induction of the pro-resolving response. However, if FPR1-induced inflammation resolution and tumor suppressor function require an early pro-inflammatory trigger and how this is achieved remains unknown. A ROS-dependent signaling is activated in response to FPR1 activation. In colorectal carcinoma (CRC) cells, we carefully analyzed this signal showing that FPR1 activation by the fMLF peptide induces biphasic ROS production: a first wave, early, mitochondrial (mROS), followed by a second, late, NADPH oxidase (NOX1)-dependent. mROS cause SHP2 phosphatase inactivation restraining its ability to dephosphorylate and inactivate SRC. SRC, in turn, allows the activation of RAS and Rac1 GTPases. RAS activates MAPK signaling, while Rac1 supports NOX1 activation, that causes the second wave of ROS, reinforcing this signaling cycle. Importantly, for the first time, we demonstrate that mROS production precedes and is necessary for pro-inflammatory mediators’ release, while NOX1-dependent ROS are only required for pro-resolving mediators’ synthesis. Pharmacological and genetic approaches and functional assays show that this signaling cascade is essential for the pro-resolving and anti-angiogenic properties of FPR1 in CRC. In conclusion, we show that FPR1 elicits pro-resolving effects in CRC activating two waves of ROS production characterized by different strength and kinetics, that parallel and are necessary for pro-inflammatory or pro-resolving mediators’ production.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"186 ","pages":"Article 117961"},"PeriodicalIF":6.9,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
