Kv channels play prominent roles in neuronal and cardiovascular systems. Mutations in Kv channels have been linked to many human diseases, such as epilepsy, heart arrhythmias, and cancers.

We systematically identified and cloned 14 <i>kcnh</i> genes in zebrafish. Then, we examined the vertebrate KCNH channel evolution by phylogenetic and syntenic analyses. Our data reveal that the three subtypes of the <i>KCNH</i> gene family had already evolved in invertebrates, long before the emergence of vertebrates. The number of vertebrate <i>KCNH</i> genes increased, most likely due to whole-genome duplications (WGDs). In addition, we examined zebrafish <i>kcnh</i> gene expression during early embryogenesis by in situ hybridization. Each subgroup's genes showed similar but distinct gene expression domains with some exceptions. Most of them were expressed in neural tissues. Notably, <i>kcnh6a</i> showed robust expression in the developing heart, consistent with its conserved role in cardiac repolarization. Additionally, a few <i>kcnh</i> genes were transiently expressed in non-neural tissues, such as somites and the notochord, suggesting they may have a unique role in embryonic development.

Recent work has implicated VPA-induced oxidative stress in cell models of neurodifferentiation, where oxidative post-translational modifications (PTMs) in undifferentiated cells, primarily protein sulfenylation (Pr-SOH), were unique compared to differentiated neurons, primarily protein S-glutathionylation (Pr-SSG). Many of these effects could be mitigated by pretreatments with an Nrf2 inducer. However, it is unclear how early-stage mouse embryos (gestational day 8.5) respond to VPA treatments. Using whole embryo culture, mouse embryos were treated with VPA. A time course assessment of glutathione/glutathione disulfide redox potentials was performed via HPLC throughout 24 h of culture. At 6 h of VPA treatment, embryos were collected for the assessment of protein redox states and specific protein PTMs via various blotting techniques. Also, at 6 h of treatment, the localization of specific PTMs was determined via whole mount staining. Some embryos were pretreated with an Nrf2 inducer. Our data demonstrated that VPA caused a sharp oxidation of redox potentials, which were the greatest between 2 and 6 h, but reverted to control levels by 24 h. Preemptive Nrf2 activation prevented VPA-induced oxidation. Redox blotting showed that VPA caused oxidation of the proteome but this could be reversed by D3T pretreatment. More specifically, Pr-SOH levels increased but Pr-SSG levels were unchanged. Increased Pr-SOH could also be reversed with prior Nrf2 activation. We conclude that embryos at these early stages of development are highly sensitive to VPA and respond more like undifferentiated cells, promoting a more pro-oxidizing outcome for proteins, increasing Pr-SOH formation vs. Pr-SSG. These findings may support specific windows of development where embryos are more susceptible to VPA-induced oxidative injury. Further understanding of redox control and regulation at these susceptible states may serve to develop preventative strategies to reduce poor developmental outcomes after exposures.</p>","PeriodicalId":15563,"journal":{"name":"Journal of Developmental Biology","volume":"14 3","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13398012/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148578735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve more refined cell types at single-cell resolution in spatial transcriptomic data, we developed a bin-based deconvolution strategy that enabled high-precision cell-type assignment.
