They also provide an excellent system to study the developmental timeline of these appendages, regulated by multiple factors. However, how another skin appendage, sebaceous gland (SG), associated with the HFs gets specified from the HF-cells is largely unknown. Here using an integrated method we demonstrate how SOX9+ early progenitor cells regulate the fate specification of the SG.

3. ⭐ GSE296563 DNMT3A 突变通过协调急性髓系白血病 (WGBS) 中的 BCAA 代谢来协调表观遗传和翻译调控
- ✍️ 作者:未知作者
- 🏷️ 关键词:leukemia、metabolism、epigenetic
- 📝 描述:Contributors : Chengyang Xu ; Yongjia Wei ; Chenxi Han ; Jian Li ; Jia Yu ; Fang WangSeries Type : Methylation profiling by high throughput sequencingOrganism : Homo sapiensAcute myeloid leukemia (AML) harboring DNMT3A mutation exhibits epigenetic dysregulation, chemoresistance and poor outcome, but the underlining mechanism remains elusive. Here, inspired by the unexpected finding that DNMT3A-mutated AML patients exhibit a unique translatome landscape, we connected this epigenetic mutation to translational dysregulation through reprogrammed branched-chain amino acid (BCAA) metabolism. Particularly, DNMT3A mutation induces DNA hypomethylation-dependent activation of BCAT1, a rate-limiting aminotransferase gene for BCAA metabolism. Thereafter, the accumulation of intracellular BCAA more profoundly alters translation of a select subset of transcripts with higher BCAA codon ratios. Accordingly, deficiency in BCAA availability reduces the translation of target genes and attenuated the proliferative advantages of DNMT3A-mutated AML cells. More importantly, the pharmacological inhibition of BCAT1 with Gabapentin normalized BCAA levels, reversed target genes translation and repressed leukemia cell growth specifically in DNMT3A-mutated AML cells. Collectively, these findings uncovered a novel epigenetics-metabolism axis, in which DNMT3A mutation boosts BCAA metabolism thereby not only forming a positive feedback loop to enhance DNA hypomethylation through alpha ketoglutarate (α-KG)-dependent ten-eleven translocation (TET) activation, but also affecting gene translation in a BCAA codon-biased manner. Moreover, the efficacy of Gabapentin in suppressing AML cell proliferation highlights the clinical relevance of targeting BCAA metabolism to improve outcomes of DNMT3A-mutated AML.

5. ⭐ GSE292303 犬和人肝细胞癌肿瘤微环境的多组学比较评估
- ✍️ 作者:未知作者
- 🏷️ 关键词:tumor、carcinoma、tumor microenvironment
- 📝 描述:Contributors : Yulia Nussbaum ; Edward Ricemeyer ; Wesley WarrenSeries Type : Expression profiling by high throughput sequencingOrganism : Canis lupus familiarisBackground: Liver cancer remains a leading cause of death in humans. Its primary form, hepatocellular carcinoma (HCC) is frequently resistant to chemotherapy and radiation and often shows insufficient response to immunotherapy. HCC in dogs can arise from various factors but is not typically associated with viral infections, cirrhosis, or alcohol consumption, the more common triggers of spontaneous HCC in humans. This distinction offers a unique comparative perspective on the intrinsic genetic drivers of the disease.Methods: Using whole exome sequencing (WES) and single nucleus RNA sequencing (snRNA-seq) in tandem, we perform a multi-omic analysis of the dog HCC tumor.Results: Mutational analysis of impactful polymorphisms revealed a conserved cross-species landscape with genes such as CTNNB1, known for highly recurrent mutations in human HCC, showing similar alterations in dogs. In dog HCC tumors, we identified major cell types commonly observed in human HCC, including T lymphocyte, endothelial, macrophage, fibroblast, hepatocyte, malignant, and non-specific proliferating types. A comparative analysis of intercellular interactions across human and dog HCC cell types revealed intriguing parallels, particularly in macrophage functionality.Conclusions: These findings underscore the need for expanded genetic studies of dog HCC to further elucidate cross-species commonalities, offering deeper insights into key aspects of HCC biology and identifying novel therapeutic targets.

6. ⭐ GSE282096 转录活性降低和剪接变化驱动衰老转录组中基因长度偏向的重编程(RNA-Seq)
- ✍️ 作者:未知作者
- 🏷️ 关键词:aging、RNA-seq、transcriptome
- 📝 描述:Contributors : Saeid M Parast ; Madhurima Das ; Marta Iwanaszko ; Ali ShilatifardSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTranscription by RNA polymerase II (RNAPII), which is essential for protein-coding gene expression and cellular function, is increasingly understood to become dysregulated with aging. Here, we use a multi-modal approach to comprehensively characterize age-dependent changes in RNAPII-mediated transcription in both mouse and human tissues. Short-read total RNA sequencing (RNA-seq) to profile nascent transcription reveals a global reduction in overall transcriptional activity/frequency in aged tissues, without apparent change in elongation rates. Transcriptomic analysis reveals a shift toward preferential expression of short genes in aged tissues, with notable upregulation of short stress-response genes and downregulation of long neurodevelopmental genes in the aged mouse brain. These results are recapitulated by analysis of total RNA-seq data from human tissues. Leveraging long-read RNA-seq, we determine that the representation of aberrant mono-exonic and intron-retention splice isoforms is increased in the aged mouse brain. Finally, we characterize the composition of RNAPII transcriptional machinery, finding that interactions between RNAPII and the Mediator complex are decreased in the chromatin of aged mouse liver and brain. Collectively, these analyses provide insight for future aging studies and reveal potential transcriptional control targets for anti-aging drug development.

- 📝 描述:Contributors : Yue Qiu ; Jingjie Mu ; Yifan Guo ; Jin-Yu Lu ; Xiaoqin Li ; Wenahn Liu ; Wenyan Xu ; Sha Song ; Xianjue MaSeries Type : Expression profiling by arrayOrganism : Drosophila melanogasterDNA repair pathways are canonically tumor-suppressive, yet emerging evidence suggests their upregulation can promote cancer progression, a paradox whose mechanisms remain poorly understood. Here, we report that activation of the Fanconi Anemia (FA) DNA repair pathway drives malignant tumor progression by reprogramming cellular senescence from a tumor-suppressive to a pro-tumorigenic state. Through an unbiased genetic screen in Drosophila, we identified that loss of Sras (homologous to human RCE1) cooperates with oncogenic RasV12 to induce slow-progressing yet highly malignant tumors. Bioinformatics analysis revealed marked upregulation of the FA pathway and Hippo signaling in these tumors. Genetic manipulation demonstrates that FA pathway activation is required for tumor growth and invasion. Mechanistically, we show that FA pathway upregulation enhances cellular senescence and triggers secretion of senescence-associated secretory phenotype (SASP) factors, particularly the cytokine Unpaired-1 (Upd1; IL-6 homolog), which in turn activates JAK-STAT signaling within tumor cells through an autocrine loop, thereby promoting tumor progression. Notably, p53 activation is dispensable for this pro-tumorigenic senescence program. FA pathway activation and its pro-tumorigenic function are conserved across multiple RasV12-driven malignant tumor models. Our findings reveal a previously unrecognized mechanism by which DNA repair machinery is co-opted to convert oncogene-induced senescence into a tumor-promoting state, with broad implications for understanding cancer progression and developing therapies targeting Ras-driven malignancies.
