- Acute myeloid leukaemia (AML) is a therapeutically challenging malignancy driven by the self-renewal, quiescence, and therapy resistance of leukaemic stem cells (LSCs). CDK8, a kinase component of the Mediator complex, regulates oncogenic transcription, and the selective CDK8/CDK19 inhibitor RVU120 (Romaciclib) targets AML cells with CD34/pSTAT5-high LSC-like characteristics; however, the epigenetic and transcriptional consequences of CDK8 blockade and actionable combinatorial strategies remain incompletely defined. Using the TEX cell line, an LSC-enriched surrogate model, we performed time-resolved RNA-seq, whole-proteome and phosphoproteomics mass spectrometry (MS), and CUT&Tag chromatin profiling following treatment with RVU120 and CCT251921. CDK8 protein-protein interactions were mapped by co-immunoprecipitation MS across five AML models, and synergy with Pelabresib (BET inhibitor) or CB6644 (RUVBL1/2 inhibitor) was assessed by high-content screening in three cell lines and three patient-derived xenograft (PDX) models. Both inhibitors suppressed STAT5 phosphorylation, induced loss of the CD34/CD38 LSC-enriched phenotype, and drove erythromegakaryocytic differentiation. Transcriptomic and proteomic responses were concordant, and CDK8 inhibition triggered widespread enhancer activation with redistribution of RNAP2, BRD3, and NFRKB. CDK8 combined with Pelabresib acted synergistically in MOLM-16 cells and two of three PDX models. These findings identify CDK8 as a transcriptional node of LSC-associated programs and provide a mechanistic rationale for combined CDK8-BET inhibition in molecularly defined AML subsets, which will require validation in functional LSC assays and primary specimens. - Source: PubMed

Using a reciprocal backcross in pigs (F×German Landrace vs. F×Piétrain) and a haplotype-agnostic RNA-seq pipeline, we profiled six fetal tissues to test sire-breed effects. We identified paternal breed-driven transcriptional divergence, with 1,176 genes differentially expressed. Transcriptional divergence was most pronounced in metabolic tissues, revealing a tissue-specific trade-off: F × GL conceptuses prioritized metabolic and energy pathways, whereas F × Pi conceptuses upregulated developmental and cell cycle processes. Allele-specific expression analysis revealed extensive, tissue-dependent -regulatory divergence, and differential ASE highlighted candidate mediators, including and (kidney), (brain), and (liver). These results indicate that paternal genetics programs fetal tissues via -regulatory variation, informing strategies to improve livestock traits. Notably, many loci overlapped known QTLs, suggesting that regulatory variants connect sire background to performance-related phenotypes and fetal programming. - Source: PubMed

Iqbal Muhammad ArsalanMurani EduardHadlich FriederReyer HenryOster MichaelTrakooljul NaresWimmers KlausPonsuksili Siriluck - Bromodomain-containing protein 4 (BRD4) is an important therapeutic target for anticancer, antiviral, and anti-inflammatory responses. Although its role in transcription, chromatin dynamics, and epigenetic programs is well recognized, recent studies have expanded the functions of BRD4 and its related bromodomain and extra-terminal (BET) family members (BRD2, BRD3, and BRDT) to other molecular and biological processes. How a universal epigenetic regulator is tailored for context-specific gene/pathway regulation is mechanistically intriguing. In this review, we highlight the importance of protein isoforms and posttranslational modifications, particularly phosphorylation, in generating the protein diversity necessary for selective factor recruitment and context-dependent regulation. Three BRD4 protein isoforms have been identified, including the universally expressed BRD4-L and BRD4-S(a) (simplified as BRD4-S), representing the long and short isoform a, and cell-/stress-specific short isoform b, BRD4-S(b). A phospho-switch mechanism controlling the open/closed state of the bromodomain and BRD4 interaction with partner proteins will also be discussed. Mechanistic understanding of BET protein action has led not only to the development of diverse bromodomain-binding compounds currently used in clinical trials but also to the discovery of a new class of small-molecule inhibitors targeting an intrinsically disordered region (IDR) of phospho-BRD4 to alter specific protein-protein interaction (PPI) networks without globally perturbing transcription programs and chromatin landscapes, thus significantly reducing off-target effects and providing new directions for therapeutic drug development. - Source: PubMed

Wu Shwu-YuanChiang Cheng-Ming - Nuclear protein in testis (NUT) carcinoma (NC) is an extremely rare and highly aggressive tumor. Non-canonical NC patients frequently have unique clinicopathological characteristics in terms of location, molecular alteration, and outcome, with morphological overlap with other tumors. Here, we report and summarize the non-canonical clinicopathological features of three unusual NC patients harboring or gene rearrangement. - Source: PubMed
