Project description:Here we report that piroxicam/cisplatin combined treatment exerts an apoptotic effect on mesothelioma cells. Genome-wide transcriptome analyses lead us to identify p21 as the possible apoptosis mediator acting as downstream target of the piroxicam/cisplatin treatment. To analyze the potential therapeutic effect of the piroxicam/cisplatin treatment at molecular level, and to identify gene expression pattern modifications following the combined treatment, we performed a transcriptional profiling on HGU133A arrays, using cells treated with piroxicam, cisplatin or with piroxicam and cisplatin, choosing the time exposures in which apoptosis induction was absent or evident (8 and 24 hours). Biological duplicates or triplicates were generated for each prototypic situation and data were analyzed using the oneChannelGUI Bioconductor package (Sanges et al., 2007), comparing untreated cells with cells treated in single or combined treatment. After quality controls, the complexity of the data set was reduced removing the non-significant probe sets, resulting in a total of 4,247 out of the 22,283 probe sets present in the microarray. To assess differential expression, linked to piroxicam, cisplatin- and the combined treatment we used an empirical Bayes method together with a false discovery rate (FDR) correction of the P-value. Specifically genes were selected using a corrected p-value M-bM-^IM-$0.05 and |log2(fc)| M-bM-^IM-%1. We detect a total of 536 differentially expressed genes.

Project description:Application of cisplatin (DDP) for treating lung cancer is restricted due to its toxicity and drug resistance. In this study, we aimed to examine whether Jinfukang (JFK), an effective herbal medicine against lung cancer, enhances DDP-induced cytotoxicity in lung cancer cells. Morphologically, we observed JFK increases DDP-induced pro-apoptosis in A549 cells in a synergistic manner. Transcriptome profiling analysis indicated that combination of JFK and DDP regulates genes involved in apoptosis-related signaling pathways. Moreover, we found the combination of JFK and DDP produces synergistic pro-apoptosis effect in other lung cancer cell lines NCI-H1975, NCI-H1650 and NCI-H2228. Particularly, we demonstrated AIFM2 is activated by the combined treatment of JFK and DDP, and partially mediate the synergistic pro-apoptosis effect. Collectively, this study gives the first evidence that activation of AIFM2 contributes to induction of pro-apoptosis by combined treatment with JFK and DDP in human lung cancer cells and provides an insight for its potential clinical application in lung cancer treatment.

Project description:The generation of pancreatic organoids from human pluripotent stem cells represents a major breakthrough for regenerative medicine and the modeling of diseases such as diabetes. However, current approaches remain inefficient due to lengthy multi-step differentiation protocols and limited functional maturity in the organoids. In this study, we overcome these challenges using multi-phase optimization screens to achieve rapid generation of functionally mature pancreatic organoids from a stable endocrine progenitor culture. We conducted stepwise culture condition screens that enabled the stable culture of multiple pancreatic progenitor cell states, including the unprecedented stable propagation of NEUROD1-expressing endocrine progenitor-like cells (EpSCs). Further transcriptomic profiling of EpSC confirmed similarity of that to previously reported endocrine progenitor populations. Using EpSCs, we significantly reduced the number of steps and timing required to generate pancreatic organoids, enabling rapid testing of conditions for organoid maturation. Utilizing this optimized protocol, we further tested conditions to promote pancreatic organoid maturation. We identified that exosome-delivered WNT5B, in combination with RSPO1 (exoW/R), could strongly induce non-canonical WNT/JNK signaling, promoting pancreatic organoid maturation. This combinatorial exosome treatment enhances epithelial organization, reduces immature cell states, and significantly improves glucose responsiveness and insulin secretion. Collectively, our work establishes a robust pancreatic differentiation platform that integrates long-term progenitor expansion with optimized organoid maturation. This system provides a reproducible experimental framework for studying pancreatic development, investigating disease mechanisms, and facilitating future translational applications involving pancreatic organoids.
