These tastes are transmitted through the activation of ion channels and receptors. Bitter taste receptors (Taste Family 2 Receptors; T2Rs) are a sub-family of 25 G-protein coupled receptor (GPCR) isoforms that were first identified in type II taste bud cells. T2Rs are activated by a broad array of bitter agonists, which cause an increase in intracellular calcium (Ca<sup>2+</sup>) and a decrease in cyclic adenosine 3’,5’-monophosphate (cAMP). Interestingly, T2Rs are expressed beyond the oral cavity, where they play diverse non-taste roles in cell physiology and disease. Here, we summarize the literature that explores the role of T2Rs in apoptosis. Activation of T2Rs with bitter agonists induces apoptosis in several cancers, the airway epithelia, smooth muscle, and more. In many of these tissues, T2R activation causes mitochondrial Ca<sup>2+</sup> overload, a main driver of apoptosis. This response may be a result of T2R cellular localization, nuclear Ca<sup>2+</sup> mobilization and/or a remnant of the established immunological roles of T2Rs in other cell types. T2R-induced apoptosis could be pharmacologically leveraged to treat diseases of altered cellular proliferation. Future work must explore additional extra-oral T2R-expressing tissues for apoptotic responses, develop methods for <i>in-vivo</i> studies, and discover high affinity bitter agonists for clinical application.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"30 3-4","pages":"674 - 692"},"PeriodicalIF":6.1,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10495-025-02091-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466725","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}

By analyzing RNA-seq data from The Cancer Genome Atlas (TCGA), 6451 differentially expressed genes (DEGs) were identified. Cox regression analysis narrowed this list to 14 MRGs with potential prognostic implications. ESCA patients were classified into two distinct subtypes (C1 and C2) based on these genes. Furthermore, leveraging the differentially expressed genes between Cluster 1 and Cluster 2, ESCA patients were classified into two novel subtypes (CA and CB). Importantly, patients in C2 and CA subtypes exhibited inferior prognosis compared to those in C1 and CB (p < 0.05). Functional enrichments and immune microenvironments varied significantly among these subtypes, with C1 and CB demonstrating higher immune checkpoint expression levels. Employing machine learning algorithms like LASSO regression, Random Forest and XGBoost, alongside multivariate COX regression analysis, two core genes: HSPD1 and MAP1LC3B were identified. A prognostic model based on these genes was developed and validated in two external cohorts. Additionally, single-cell sequencing analysis provided novel insights into esophageal cancer microenvironment heterogeneity. Through Coremine database screening, Icaritin emerged as a potential therapeutic candidate to potentially improve esophageal cancer prognosis. Molecular docking results indicated favorable binding efficacies of Icaritin with HSPD1 and MAP1LC3B, contributing to the understanding of the underlying molecular mechanisms of esophageal cancer and offering therapeutic avenues.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"30 3-4","pages":"1021 - 1041"},"PeriodicalIF":6.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143413067","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}

It is illustrated that the uptake of MPs enhances levels of autophagy by activating the mTOR pathway. MPs can also promote the disorder of intestinal flora and intestinal inflammation, serving as an essential component in the onset and advancement of CRC. These results indicated that microplastic pollutants in colorectal cancer could mediate protective autophagy through the mTOR/ULK1 axis, which is one of the new reasons for chemo-resistance in CRC under the background of increasingly serious microplastics pollution.

In this review article, we summarize the cell death subroutines in the erythroid precursors (apoptosis, necroptosis, and ferroptosis) in comparison to mature erythrocytes (eryptosis and erythronecroptosis) to highlight the consequences of organelle clearance and associated loss of multiple components of the cell death machinery upon erythrocyte maturation. Recent advances in understanding the role of erythrocyte RCDs in health and disease have expanded potential clinical applications of these lethal subroutines, emphasizing their contribution to the development of anemia, microthrombosis, and endothelial dysfunction, as well as their role as diagnostic biomarkers and markers of erythrocyte storage-induced lesions. Fas signaling and the functional caspase-8/caspase-3 system are not indispensable for eryptosis, but might be retained in mature erythrocytes to mediate the crosstalk between both erythrocyte-associated RCDs.

SEC23A, a core component of the COPII vesicle trafficking system, is of critical importance with regard to protein transport and cellular homeostasis. Nevertheless, its function in CRC progression and chemoresistance remains uncertain. The present study investigates the correlation between SEC23A expression and sensitivity to 5-fluorouracil (5-FU), a widely used chemotherapeutic agent, with particular emphasis on ER stress-induced apoptosis. Methods: A bioinformatic analysis was conducted to evaluate SEC23A expression in CRC and its association with patient prognosis. Chemotherapy sensitivity was predicted using GDSC data and validated experimentally using CRC cell lines with manipulated SEC23A expression. In order to explore the role of SEC23A in acquired drug resistance, patient-derived xenograft (PDX) models and 5-FU-resistant cell lines were employed. Apoptosis assays, cell cycle analysis, and ER stress modulation experiments were performed to elucidate the underlying mechanisms. Results: SEC23A expression was significantly reduced in CRC samples compared to normal tissues. This reduction was linked to a poorer prognosis, including both overall and disease-specific survival. A correlation was observed between low SEC23A expression and increased resistance to 5-FU, as evidenced by both bioinformatic predictions and in vitro experiments. In PDX models, metastatic lesions exhibited decreased SEC23A expression following 5-FU treatment in comparison to primary tumors. Overexpression of SEC23A in 5-FU-resistant cell lines restored sensitivity to the drug and increased apoptosis. Bioinformatic and experimental analyses revealed a robust correlation between SEC23A and ER stress-related apoptotic pathways. Elevated expression of SEC23A was observed to facilitate the accumulation of misfolded proteins in response to 5-FU treatment, which in turn resulted in increased ER stress and apoptosis. Conclusions: SEC23A plays a crucial role in modulating the sensitivity of CRC cells to 5-FU by regulating ER stress-induced apoptosis. Its downregulation contributes to chemoresistance, indicating that SEC23A may serve as a prognostic marker and therapeutic target in CRC. Strategies aimed at upregulating SEC23A or enhancing ER stress may provide new avenues for overcoming chemoresistance and improving treatment outcomes for CRC patients.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"30 3-4","pages":"976 - 990"},"PeriodicalIF":6.1,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10495-025-02084-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143188161","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}

Single-cell cohort analysis further demonstrates that patients with low TCR scores possess an immune-active tumor microenvironment (TME), with T/NK cells enhancing interactions with myeloid cells through signaling networks such as MIF, MK, and SPP1. In response to these changes in the TME, patients with high TCR scores exhibit poorer outcomes and shorter survival in immunotherapy cohorts.
