1. ⭐ GSE291339 CDK4/6 抑制剂 Palbociclib 克服了 Venetoclax 耐药机制,并在急性髓系白血病中优于单药治疗 [RNA-Seq]
- ✍️ 作者:未知作者
- 🏷️ 关键词:leukemia、resistance、RNA-seq
- 📝 描述:Contributors : Melissa L Stewart ; Jessica Gibbs ; Andy Kaempf ; Jeffrey W TynerSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensVenetoclax (ven) combined with the hypomethylating agent azacytidine (aza) is a widely used therapy for Acute Myeloid Leukemia (AML), however, most patients develop resistance. Using RNASeq, we identified loss of Ikaros (IKZF1) as a potential resistance mechanism to ven+palbo. Examination of cells with IKZF1-loss revealed upregulation of the receptor, AXL, with concordant AXL inhibitor sensitivity in AML tumors harboring IKZF1 mutations. This work suggests that the combination of ven+palbo is a potential novel therapy for AML for potential subpopulations that may benefit the most from this treatment, as well as targeting translation as a means to overcome ven resistance.

- ✍️ 作者:未知作者
- 🏷️ 关键词:leukemia、regex:onco(logy|logist|gene|genic)、RNA-seq
- 📝 描述:Contributors : Bi Shi ; Yongkun Luan ; Hao Jiang ; Wei LiSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiens ; Mus musculusOncogenic transcription represents a crucial event in MLL rearranged (MLLr) leukemia, yet the precise role of transcription co-activators in MLL-fusion protein-associated transcription and their contribution to leukemogenesis remain incompletely understood. Here, we demonstrate that AKAP95 is notably up-regulated in both MLLr patients and in MLL-AF9-transformed mouse bone marrow. AKAP95 proves essential for initiating mouse MLL-AF9 leukemia, exhibiting widespread DNA binding across the genome, particularly at gene promoters. Interaction with the translocated MLL1 fragment primarily occurs through phase separation mechanisms. AKAP95’s RNA-binding properties, coupled with its phase separation behavior, govern its binding to pre-mRNA and concurrent transcriptional regulation. Importantly, we engineered a peptide to disrupt its phase separation, effectively attenuating AKAP95-mediated transcriptional co-activation and inhibiting the growth of MLLr cell lines. These findings illustrate a vivid example of an RNA-binding protein orchestrating transcription and tumorigenesis via phase separation, underscoring the potential for targeting oncogenic condensation mechanisms therapeutically.

- ✍️ 作者:未知作者
- 🏷️ 关键词:leukemia、resistance
- 📝 描述:Contributors : Melissa L Stewart ; Jessica Gibbs ; Daniel Bottomly ; Shannon K McWeeney ; Jeffrey W TynerSeries Type : OtherOrganism : Homo sapiensVenetoclax (ven) combined with the hypomethylating agent azacytidine (aza) is a widely used therapy for Acute Myeloid Leukemia (AML), however, most patients develop resistance. A genome-wide CRISPR screen showed that loss of genes involved in translation conferred sensitivity to ven but not ven+palbo. Accordingly, we show that increased translation occurs after AML cells are challenged with ven, and ven+palbo blocks this increase. We also found that loss of BAX, which leads to ven resistance, was overcome by combination with CDK4/6 inhibitors. Conversely, loss of RB1, a known mechanism of resistance to CDK4/6 inhibitors, was mitigated by ven+palbo. This work suggests that the combination of ven+palbo is a potential novel therapy for AML for potential subpopulations that may benefit the most from this treatment, as well as targeting translation as a means to overcome ven resistance.

- ✍️ 作者:未知作者
- 🏷️ 关键词:immune、single-cell
- 📝 描述:Contributors : Lei Zhao ; Chao WuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusAging profoundly impacts bone homeostasis and regeneration, yet the cellular and molecular mechanisms underlying periosteal aging remain poorly understood. Using single-cell RNA sequencing, we profiled the periosteum of 3-, 9-, and 18-month-old mice, revealing age-related shifts in progenitor, neutrophil, and macrophage subpopulations. Aging reduced mesenchymal cell populations and impaired osteogenic potential, disrupting periosteal homeostasis. Periosteal progenitor subsets exhibited distinct aging trajectories: Dpt⁺ fibrous-layer cells undergoing early senescence, while Postn⁺ progenitors showed osteogenic decline. Aging also shifted immune profiles, increasing inflammatory Cd38hi macrophages and dysfunctional Nlrp3hi neutrophils, further disrupting bone homeostasis. Notably, aged progenitor cells upregulated CSF1 and CXCL signaling, driving macrophage and neutrophil infiltration, exacerbating bone loss. Our findings provide a comprehensive periosteal aging atlas, highlighting disrupted progenitor-immune crosstalk as a key driver of bone homeostasis imbalance and impaired regeneration, offering potential therapeutic targets for age-related bone disorders.

9. GSE280833 组蛋白H4对组蛋白基因转录的细胞周期依赖性抑制

- 📝 描述:Contributors : Kami Ahmad ; Matt Wooten ; Brittany N Takushi ; Velinda Vidaurre ; Xin Chen ; Steven HenikoffSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Drosophila melanogaster ; Homo sapiensIn all eukaryotes DNA replication is coupled to histone synthesis to coordinate chromatin packaging of the genome. Canonical histone genes coalesce in the nucleus into the Histone Locus Body (HLB), where gene transcription and 3’ mRNA processing occurs. Both histone gene transcription and mRNA stability are reduced when DNA replication is inhibited, implying that the Histone Locus Body senses the rate of DNA synthesis. In Drosophila melanogaster, the S-phase-induced histone genes are repeated in an ~100 copy repeat unit array, whereas in humans, these histone genes are scattered. In both organisms these genes coalesce into Histone Locus Bodies.

2. USP20 驱动的胆固醇代谢将炎症信号传导与胰腺癌的恶性肿瘤和基质共同进化联系起来

- 🏷️ 关键词:肿瘤、代谢
- 📝 描述:Secret hovertext: 炎症信号传导、代谢重编程和基质复杂性已成为胰腺导管腺癌 (PDAC) 的核心标志。这些程序之间的串扰可能代表同时扰乱多个肿瘤促进过程的潜在靶点。通过整合来自临床队列、患者来源的类器官和本土模型的多组学数据,我们发现 PDAC 中的肿瘤内源性炎症级联反应是甲羟戊酸途径劫持的主要调节因子,这推动了恶性进展和基质共同进化。TNFSF13B+ 肿瘤相关巨噬细胞激活肿瘤上皮细胞中的 STAT3 信号传导,导致 USP20 的转录上调。这种去泛素酶稳定了 HMGCR,以增强甲羟戊酸通量,导致胆固醇和香叶基香叶酰焦磷酸盐的产生过量。USP20 介导的代谢改变诱导的 YAP/TAZ 信号传导刺激促进肿瘤细胞增殖并触发癌症相关成纤维细胞 (CAF) 的激活。使用选择性抑制剂对 USP20 进行基因消融或药理学抑制可逆转肿瘤代谢失调,从而抑制肿瘤生长和基质结缔增生。此外,USP20 抑制与抗 PD-1/抗 CTLA-4

- 📝 描述:Secret hovertext: 免疫检查点阻断治疗对微卫星不稳定 (MSI) 结直肠癌 (CRC) 非常有效。然而,微卫星稳定 (MSS) 肿瘤对免疫治疗具有内在的耐药性。在这里,我们试图通过表征 MSS 和 MSI 肿瘤模型的免疫谱来更好地了解 CRC 中抗 PD-L1 治疗耐药的机制。虽然两种肿瘤类型都表现出瘤内 CD8+ T 细胞和 PD-L1 表达,但耗尽的 CD8+ T 细胞表型不同。在 MSS 肿瘤中,耗尽的 CD8 + T 细胞共表达 PD-1 和 TIGIT,并表现出终末耗尽特征,细胞因子分泌低,细胞毒性功能有限。相比之下,MSI 肿瘤中的 PD-1+ CD8+ T 细胞不表达 TIGIT,表现出更高的细胞因子和细胞毒性活性。有趣的是,免疫抑制性 M2 样肿瘤相关巨噬细胞(TAM)在 MSI 肿瘤中积累,并与 PD-1+ TIGIT+ CD8+ T 细胞频率呈正相关。M2 样 TAM 耗竭降低了 TIGIT

- 📝 描述:Researchers have discovered that prostate cancer depends on two key enzymes, PDIA1 and PDIA5, to survive and resist therapy. When blocked, these enzymes cause the androgen receptor to collapse, killing cancer cells and enhancing the effects of drugs like enzalutamide. They also disrupt the cancer’s energy system, striking it on multiple fronts. This breakthrough could open a new path to overcoming drug resistance in advanced prostate cancer.
