Traditional cell analytics involve manual processes, such as cell counting or reagent-based approaches that are user-dependent and prone to bias. Semi-automated systems for counting cells, tracking cell growth, and determining viability have been introduced over the past decades. However, these methods are often time-consuming, require labeling steps, and involve costly instrumentation and consumables. Changes in cell growth and/or viability create biological patterns that can be interpreted by artificial intelligence (AI). Here, we report the development and validation of SnapCyte™, an AI application that performs accurate, unbiased, label- and reagent-free cell analyses from basic cell culture images. Using cell lines with diverse morphologies in various culture conditions, we generated a comprehensive and fully annotated image database that was used for AI education. Convolutional neural networks were employed for cell localization and iterative training loops until a stable performance of >95% accuracy was obtained for all readouts. The fully trained AI demonstrated high Precision and Recall and performed with greater accuracy and less variation as compared to standard methods. As the SnapCyte analyses are performed on cell images only, data acquisition is non-invasive to the experimental setup, enabling real-time use of cells in downstream assays. In summary, SnapCyte is a fast and accurate cell analytics platform, resistant to user variations and independent of reagents or specific equipment, with improved performance over current cell analytics methodologies.</p>","PeriodicalId":9735,"journal":{"name":"Cell Death Discovery","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147670772","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}

Triggering receptor expressed on myeloid cell 2 (TREM2)-mediated microglial phagocytosis of inhibitory synapses may play a pivotal role in epileptogenesis; however, the role of TREM2 in FS-induced epilepsy remains unclear. We established a Sprague-Dawley rat model of juvenile prolonged FS to analyze the associated molecular changes, epileptic susceptibility, and seizures. Our results confirmed that prolonged FS resulted in increased TREM2 levels, excessive phagocytosis by activated microglia targeting inhibitory synapses, and elevated epileptic susceptibility and seizures. Administration of a CD33 agonist (monosialoganglioside 1, GM1), a negative moderator of TREM2 that reduces its levels, attenuated microglial phagocytosis of inhibitory synapses and weakened susceptibility to epilepsy and seizures. The inhibitory effects of TREM2 knockdown were similar to those of CD33 activation. Blocking the outward-facing region of phosphatidylserine (PtdSer) to prevent TREM2 recognition resulted in increased TREM2 levels and deteriorated microglial activation. Finally, although vesicular GABA transporter (VGAT) levels were higher in the prolonged FS rats treated with annexin V, susceptibility to epilepsy and seizures were aggravated. This study revealed that reducing TREM2 levels may inhibit prolonged FS-induced epileptogenesis by alleviating the phagocytic function of activated microglia targeting inhibitory synapses, while preventing TREM2 from recognizing PtdSer has the opposite effect.</p>","PeriodicalId":9735,"journal":{"name":"Cell Death Discovery","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147662272","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 potential of bacterial α-helical proteins to form analogous anticancer complexes remains unexplored. In the current study, we demonstrate that α-helical proteins of bacterial origin can form tumoricidal complexes with sodium oleate. Using non-hemolytic toxin A (NheA), an inactive component of the native tripartite (NheABC) toxin complex from Bacillus thuringiensis, we show that NheA, upon mixing with sodium oleate (NheA-O), forms potent tumoricidal complexes against colorectal cancer cells. The NheA-O complex binds to the plasma membrane of tumor cells, disrupting the function of cellular organelles and ultimately causing cell death. Mechanistically, NheA-O induces ACSL4 and suppresses GPX4 expression, which ultimately leads to the accumulation of lipid peroxidation, following suppression of β-catenin signaling. The suppression of β-catenin signaling and its target proteins ultimately leads to suppression of colorectal cancer tumorigenesis. Functionally, NheA-O inhibits tumor cell migration, spheroid formation, clonogenic potential, ATP production and induces lipid peroxidation. These findings establish that bacterial α-helical proteins, like their human counterparts, can be engineered to form tumoricidal complexes with sodium oleate. Our work highlights NheA-O as a novel candidate that causes activation of ferroptosis-like cell death in target cancer cells, leading to intracellular organelles dysfunction. Moreover, NheA-O activity synergizes with RSL3, and NheA-O mediated cell death is antagonized by Fer-1, indicating the role of NheA-O in inducing ferroptosis-like cell death. Overall, these results describe NheA-O as a novel therapeutic agent to combat tumorigenesis by targeting tumor cell membrane and proteasomal degradation of GPX4 to trigger ferroptosis-like cell death and expands the paradigm of tumoricidal protein-lipid complexes functionality across biological kingdoms.</p>","PeriodicalId":9735,"journal":{"name":"Cell Death Discovery","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13076691/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147662282","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}

Nanoencapsulation (AuNPs) of berry-derived polyphenolic compounds was influenced by limited clinical use due to poor stability and bioavailability. Several physicochemical characterizations employed include TEM, FTIR, and targeted UPLC/MS-QQQ assays.

Here, we observed that elevated NAT10 levels promote cisplatin chemoresistance in gastric cancer cells. On the contrary, knockdown of NAT10 enhances the sensitivity of cisplatin-resistant gastric cancer cells to cisplatin, both in vitro and in vivo. Mechanistically, NAT10 binds to DUSP1 mRNA and catalyzes its ac4C modification at positions C327, C330, and C331 within the coding sequence (CDS) region, thereby enhancing the stability of DUSP1 mRNA and increasing the abundance of DUSP1 protein. Furthermore, NAT10 mediates resistance to cisplatin-induced apoptosis through DUSP1 via the JNK and ERK signaling pathways. Additionally, NAT10 can upregulate PD-L1 expression via FOSB. The combination of a NAT10 inhibitor and an anti-PD-1 antibody synergistically enhances the antitumor efficacy against cisplatin- resistant gastric cancer cells in murine models. Taken together, these findings offer novel insights into the role and mechanism of NAT10 in the crosstalk between cisplatin chemoresistance and immunosuppression in gastric cancer.
