In recent years, gasotransmitters such as nitric oxide, carbon monoxide and hydrogen sulfide have been suggested to play a regulatory role in necroptosis. This paper reviews the evidence that these gasotransmitters are involved in the regulation of necroptosis by influencing the production of reactive oxygen species, regulating the modification of S subunits of RIPK1 and RIPK3, regulating inflammatory mediators, and signal transduction. In addition, this review explores the potential therapeutic applications of these gasotransmitters in pathological conditions such as cardiovascular disease and ischemia-reperfusion injury. Although some studies have revealed the important role of gasotransmitters in necroptosis, the specific mechanism of action is still not fully understood. Future research is needed to further elucidate the molecular mechanisms of gasotransmitters in precisely regulating necroptosis, which will help develop new therapeutic strategies to prevent and treat related diseases.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"30 3-4","pages":"616 - 635"},"PeriodicalIF":6.1,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10495-024-02057-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assessed the effects of eight essential oils active constituents on T24 and MCF-7 cell lines in both dose- (16–1024 µg/mL) and time-dependent manners. Among these, five EO-ACs (citral, carvacrol, eugenol, geraniol, and thymol) exhibited IC<sub>50</sub> values, ranging from 24 µg/mL to 34 µg/mL, as determined by the MTT assay over 72 h.

Of particular concern is arsenic-induced apoptosis–driven neurodegeneration. Our major objective was to investigate the molecular signaling intricacies associated with arsenic-induced death of cerebellar neurons and to propose folic acid as a possible intervention. Swiss albino mice were treated with sodium arsenite (orally: 0.05 mg/L) and folic acid (orally:10 mg/kg) for 28 days. We observed that arsenic caused noticeable cell loss with morphological alterations in cerebellum, which was remarkably restored by folic acid. Arsenic-induced morphological alterations consequently perturbed transcriptional activities of neural stem cell factors-SOX2 and KLF9, which resulted in the suppression of pro-neurogenic mediators NeuroD1, Neurogenin2, calbindin and NeuN. Interestingly, folic acid reversed the expression of these critical pro-neurogenic mediators to mitigate these degenerative changes to promote neurogenesis. Delving deep, we found that folic acid rescued arsenic-exposed cerebellum from severe oxidative and pro-inflammatory insults by increasing antioxidants like SOD, Catalase, GSH, upregulating Nrf2 and downregulating M1 macrophages, JNK, NF-κB, and STAT3 activities. For the first time, we are reporting that arsenic induced a G1/S cell cycle arrest and triggered apoptosis in mouse cerebellum by activating the p53-p21 axis, downregulating CDKs and instigated p21-mediated suppression of SOX2 transcriptional activity. Folic acid abated such alterations by modulating the p53/p21/SOX2 axis. Collectively, the anti-apoptotic and pro-neurogenic effects of folic acid present it as a promising therapeutic candidate, warranting further research into its efficacy against metal-induced neurodegenerative disorders.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"30 3-4","pages":"710 - 733"},"PeriodicalIF":6.1,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142885128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brazilin, an organic compound known for its potent antioxidant and anti-inflammatory properties, has not been thoroughly studied for its potential impact on lipopolysaccharide (LPS)-induced ALI. Here, we found that pretreatment of brazilin mitigated LPS-induced lung injury and inflammation by inhibiting mitochondrial oxidative stress and ferroptosis, both in vivo and in vitro. Sirtuin 3 (SIRT3) was identified as a downstream target of brazilin, and overexpression of SIRT3 mirrored the protective effects of brazilin against LPS-induced ALI. Additionally, SIRT3 contributed to the upregulation, mitochondrial translocation and deacetylation of glutathione peroxidase 4 (GPX4). Through screening potential acetylation sites on GPX4, we identified lysine 148 (K148) as the residue deacetylated by SIRT3. Mutating the acetylation site of GPX4 within mitochondria (mitoGPX4-K148R) reduced LPS or SIRT3 knockdown-induced GPX4 acetylation, oxidative stress, and ferroptosis, ultimately ameliorating ALI. In conclusion, our study demonstrates the beneficial effects of brazilin in treating LPS-induced ALI. Brazilin enhances SIRT3 expression, which in turn deacetylates and facilitates the mitochondrial translocation of GPX4, thereby reducing mitochondrial oxidative stress and ferroptosis. These findings suggest that the SIRT3/GPX4 pathway may represent a critical mechanism, and brazilin emerges as a promising therapeutic candidate for ALI.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"30 3-4","pages":"768 - 783"},"PeriodicalIF":6.1,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10495-024-02058-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142885132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
