1. ⭐ GSE337809 CYP3A4介导的代谢变异性驱动非小细胞肺癌靶向治疗的耐药性和全身毒性
- ✍️ 作者:未知作者
- 🏷️ 关键词:cancer、metabolic、resistance

Further, although targeted therapies are typically well tolerated, a subset of patients displays dose-limiting adverse effects. Therapy resistance is generally considered to be a tumor-intrinsic phenomenon, mediated by cell-intrinsic or microenvironmental mechanisms. We found that hyperactivation of CYP3A4, a P450 family enzyme, can lead to tumor-extrinsic resistance by altering pharmacokinetics and reducing systemic and tumor drug exposure, whereas reduced CYP3A4 activity is expected to increase systemic toxicities. Retrospective analysis of clinical cohorts suggests that variability in CYP3A4 activity might be a major contributor to variability in clinical outcomes. To understand the consequences of altered drug metabolism, we developed a mathematical model linking variability in CYP3A4 activity with temporal variability in systemic drug concentrations. These in silico studies indicate that the impact of altered CYP3A4 activity can be mitigated by altering drug dosing and intervals. Further, we demonstrate that tumor sensitivity can be restored by pharmacological inhibition of CYP3A4. These findings establish systemic metabolic variability as a clinically actionable driver of both resistance and toxicity and provide a framework for personalized dosing to improve safety and efficacy of targeted therapy. The Bulk RNA sequencing data is from mouse livers, either untreated or treated with candidate drug JIB-04 to assess the change in gene expression landscape.

7. GSE291140 AMPK抑制多种细胞死亡通路以维持肿瘤相关巨噬细胞比例并促进肿瘤进展
- ✍️ 作者:未知作者
- 🏷️ 关键词:tumor、macrophage
- 📝 描述:Contributors : Ruixuan Wang ; Di Liu ; Huan Wang ; Li TangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTumor-associated macrophages (TAMs) are a major immune cell population in the tumor microenvironment (TME). This part depends on their capacity to resist cell death by adapting to the harsh tumor microenvironment, characterized by nutrient deprivation and the accumulation of metabolic waste, through metabolic reprogramming. This enables TAMs to not only utilize excess metabolites and metabolic waste in the tumor microenvironment as energy sources, but also to cope with metabolic stress by upregulating cysteine uptake and activating hypoxia-inducible factors, thereby maintaining their survival and function. However, the core genes that suppress TAM death in response to the metabolic dynamics of the tumor microenvironment during tumor progression remain unknown. In this study, we used proteomics analysis combined with experimental validation found that the degree of TAM apoptosis decreased while the level of AMPK activation increased during tumor progression. Notably, myeloid-specific knockout of AMPK significantly inhibits tumor growth, reduces TAM proportion in the tumor, and weakens its pro-tumor phenotype. Bulk RNA sequencing data analysis further revealed that specific knockout of AMPK in TAMs triggers multiple forms of cell death, including apoptosis, ferroptosis, and necroptosis. Further experimental validation confirmed that AMPK knockout not only induces apoptosis and ferroptosis in TAMs but may also trigger disulfidptosis. Mechanistic research suggested that AMPK might regulate cysteine uptake and the pentose phosphate pathway to inhibit ferroptosis and disulfidptosis in TAMs. In conclusion, this study identifies AMPK as a key regulator that responds to the metabolic dynamics of the TME and inhibits various forms of cell death in TAMs, providing new theoretical insights for TAM-targeted metabolic therapies.

8. GSE330762 歌舞伎综合征 I 型成纤维细胞多组学数据集:来自原代皮肤成纤维细胞的批量 RNA-seq 谱
- ✍️ 作者:未知作者
- 🏷️ 关键词:RNA-seq
- 📝 描述:Contributors : Emile Danvin ; Paolo Salerno ; Eleonora Di Venere ; Gabriella Squeo ; Dario Righelli ; Giuseppe MerlaSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensKabuki syndrome type 1 (KS1) is a rare congenital disorder caused by heterozygous loss-of-function mutations in KMT2D – an H3K4 histone methyltransferase. While KMT2D function during early development is increasingly understood, the transcriptional and chromatin accessibility consequences of its loss in differentiated somatic tissues remain poorly characterized. We present a multi-omic dataset from primary dermal fibroblasts of seven individuals with KS type I and nine unaffected donors. The dataset comprises bulk RNA-seq from sixteen donors (nineteen libraries across two sequencing batches, including three donors sequenced in both batches to assess technical replicability) and ATAC-seq from ten donors (six KS, four controls). All libraries were processed through standardized nf-core pipelines, with differential analyses performed using DESeq2 with RUVSeq batch correction. This resource is intended to facilitate research on Kabuki syndrome type 1 and by expanding the available models for studying the group of mendelian disorders known as chromatinopathies.
