To enable this, it is crucial to assess how transcriptional signatures, cellular organisation and composition of organoids compare to in vivo counterparts. However, spatial transcriptomics has been challenging to apply to organoids to elucidate regional molecular identity. This study presents the first systematic profiling of multiple stem cell derived organoid models (brain, heart muscle, heart valve, kidney, lung, cartilage, and haematopoietic) with Stereo-seq, a full transcriptome, spatial assay using on-chip in situ RNA capture. It describes assay optimisation for characterisation, use of multiple organoid samples on a single chip, assesses limitations in RNA capture efficiency compared to reference tissues. Furthermore, it introduces a bespoke analysis method that partitions samples into regions for characterisation. These findings inform future works to characterise organoids using spatial transcriptomics, providing insights in optimising RNA capture of multiple organoids across a chip and regional analysis.

5.GSE327098 EZH2阻断通过破坏乳腺癌的代谢和DNA修复网络逆转阿霉素耐药性

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、metabolic、resistance
  • 📝 描述:Contributors : Xiaomin Wang ; Yunxiao Mai ; Yuhang Ding ; Wenlong ChenSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensBackground: Doxorubicin (DOX) resistance remains a major obstacle to effective chemotherapy in breast cancer. However, the pharmacologically actionable regulators sustaining this resistant phenotype and its therapeutic vulnerabilities remain incompletely defined. Methods: DOX-resistant breast cancer cell models were established and treated with the EZH2 inhibitors tazemetostat or GSK126, alone or in combination with DOX. Cell viability, oxidative stress, DNA damage, and mitochondrial function were assessed in vitro. Transcriptomic profiling was performed to identify pathway alterations. A pH-responsive liposomal system for delivery of DOX and tazemetostat was developed and evaluated in vivo. Results: EZH2 was highly expressed in breast cancer and correlated with poor clinical outcomes. DOX treatment induced adaptive upregulation of EZH2 in both sensitive and resistant cells. Pharmacological inhibition of EZH2 markedly restored DOX sensitivity and exhibited strong synergistic cytotoxicity in resistant models. EZH2 blockade enhanced DOX-induced oxidative stress and DNA damage, with concomitant suppression of multiple DNA repair pathways and increased γH2AX accumulation. Transcriptomic and functional analyses revealed disrupted mitochondrial function and energy metabolism, characterized by loss of mitochondrial membrane potential and ATP depletion. In vivo, combined EZH2 inhibition and DOX significantly suppressed tumor growth, while pH-responsive liposomal delivery further enhanced antitumor efficacy and reduced systemic toxicity. Conclusion: EZH2 is a critical determinant of DOX resistance in breast cancer by sustaining DNA damage tolerance and metabolic homeostasis. Pharmacological targeting of EZH2 in combination with DOX represents a rational strategy to overcome chemoresistance in breast cancer.

9. GSE293974 空间分辨谱分析和类固醇核受体足迹分析揭示了无序 N 端结构域在基因组靶向和 AP-1 相互作用中的作用

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatially、genome
  • 📝 描述:Contributors : Zigdon Inbal ; Shoham Achinoam ; Mindel Vladimir ; Manadre Wajd ; Yahav Har-Shai Dekel ; Antebi Yaron ; Barkai NaamaSeries Type : Other ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiens ; Mus musculus ; Saccharomyces cerevisiaeTranscription factors (TFs) regulate gene expression by binding to cis-regulatory regions within vast genomes. In budding yeast, intrinsically disordered regions (IDRs) emerged as key effectors of genome preferences, but whether this holds in the complex mammalian genomes remains unclear. Mammalian TFs are enriched with long IDRs, exemplified by the disordered N-terminal domains (NTDs) of the nuclear steroid receptors (SRs). Here, by comparing genomic locations of three SRs and their truncation mutants, we show that the NTDs direct the selection of SR target sites. Footprint analysis revealed that SR mutants lacking the NTD become dependent on the AP-1 motif and further suggest that the NTD can direct genome recognition independent of co-binding TFs, which we confirmed by testing SR binding across the budding yeast genome. Our results suggest that IDRs assist in defining the TF binding targets, opening new avenues for modulating activities of therapeutically relevant TFs.

5. 这种“主控基因”可能正在驱动胰腺癌的扩散。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer
  • 📝 描述:A gene called KLF5 may be a key force behind the spread of pancreatic cancer—but not in the way scientists expected. Rather than mutating DNA, it rewires how genes are turned on and off, helping tumors grow and invade new areas. Researchers found it plays a major role in metastatic cells and even controls other genes linked to cancer progression. The discovery opens the door to new treatments that target cancer’s epigenetic “control system.”
