Its mechanism of action involves binding to β-tubulin subunits, leading to the stabilization of microtubule polymers and subsequent cell cycle arrest. Despite its efficacy, PTX is associated with significant adverse effects, most notably peripheral neurotoxicity and neuropathic pain, which represent the primary dose-limiting side effects. In sensory neurons, PTX affects multiple molecular pathways, with early alterations in excitability and calcium signaling following acute drug exposure. To investigate these mechanisms, we employed a combination of calcium imaging, electrophysiological techniques, and pharmacological approaches to explore the role of ORAI channels in the excitability and calcium dynamics of mouse dorsal root ganglion neurons. Our findings reveal that acute exposure to low doses of PTX triggers IP₃-dependent calcium release and activates a store-operated calcium entry through STIM-ORAI dependent I_CRAC. Moreover, acute PTX application induced the activation of a sustained calcium inward current, V_m depolarization and triggered action potential firing that was strongly attenuated by I_CRAC inhibition. Molecular analyses further revealed a significant upregulation of <em>Orai1, Orai2</em>, and <em>Stim2</em> mRNA levels, accompanied by elevated ORAI1 protein expression, in a rat model of paclitaxel-induced peripheral neuropathy. These results suggest that ORAI and STIM proteins represent promising molecular targets for developing therapies aimed at mitigating the side effects of PTX.</div></div>","PeriodicalId":9678,"journal":{"name":"Cell calcium","volume":"130 ","pages":"Article 103040"},"PeriodicalIF":4.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190172","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}

However, the extent to which cardioprotection by H₂S involves improvement in Ca²⁺ handling remains unclear. Although H₂S has been reported to influence the function of key Ca²⁺ handling proteins, most studies have focused on acute administration of H₂S donors in isolated cardiomyocytes, rather than in a therapeutic context. In this study, we used a rat model of hypertension induced by abdominal aortic coarctation (AAC) to evaluate the therapeutic potential of NaHS, an H₂S donor, on LVH and Ca²⁺ handling. After 8 weeks of AAC, hypertensive rats developed moderate LVH, which was accompanied by a reduction in both the amplitude and the rate of rise of systolic Ca²⁺ transients, as well as a decrease in sarcoplasmic reticulum (SR) Ca²⁺ load. Despite the reduced SR Ca²⁺ load, the frequency of diastolic Ca²⁺ sparks remained high, while the incidence and propagation rate of spontaneous Ca²⁺ waves significantly increased, suggesting enhanced diastolic SR Ca²⁺ leak, most likely due to hypersensitivity of ryanodine receptors (RyR2) to Ca²⁺. On the other hand, NaHS administration during the final 4 weeks of AAC reverted both LVH and hypertension, and increased SR Ca²⁺ reuptake mediated by the SR Ca²⁺ ATPase (SERCA2a). However, NaHS treatment failed to restore the amplitude and rate of rise of systolic Ca²⁺ transients or SR Ca²⁺ load. Furthermore, SR Ca²⁺ leak might have worsened, since spontaneous Ca²⁺ waves increased. In conclusion, NaHS treatment does not appear to normalize all Ca²⁺ handling properties during hypertensive LVH. On the contrary, NaHS may exert an arrhythmogenic effect, likely due to enhanced SERCA2a activity under conditions of unresolved RyR2 Ca²⁺ hypersensitivity.</div></div>","PeriodicalId":9678,"journal":{"name":"Cell calcium","volume":"128 ","pages":"Article 103015"},"PeriodicalIF":4.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769152","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}
