Description
Methylation of histone H3 lysine 4 (H3K4me) at actively expressed, cell type-specific genes is established during development by the Trithorax group of epigenetic regulators. In mammals, the Trithorax family includes KMT2A-D (MLL1-4), a family of SET domain proteins that function in large complexes to impart mono-, di-, and trimethylation at H3K4. Individual KMT2s and their co-factors are essential for embryonic development and the establishment of correct gene expression patterns, presumably by demarcating the active and accessible regions of the genome in a cell specific and heritable manner. Despite the importance of H3K4me marks in development, little is known about the importance of histone methylation in maintaining gene expression patterns in fully differentiated and non-dividing cell types. In this report, we utilized an inducible cardiac-specific Cre driver to delete the PTIP protein, a key component of a H3K4me complex, and ask whether this activity is still required to maintain the phenotype of terminally differentiated cardiomyocytes. Our results demonstrate that reducing the H3K4me3 marks is sufficient to alter gene expression patterns and significantly augment systolic heart function. These results clearly show that maintenance of H3K4me3 marks is necessary for the stability of the transcriptional program in differentiated cells. The array we performed allowed us to identify genes that are regulated by PTIP and histone methylation.

Description
Aberrant expression of homeobox transcription factor HOXA9 is a central component of the leukemogenic program driven by diverse oncogenes. Here we show that HOXA9 overexpression in myeloid progenitor cells and pro-B cells leads to significant rearrangement of the epigenetic landscape with prominent emergence of cancer specific de novo enhancers. HOXA9 acts as a pioneer factor at the de novo enhancers and is required for recruitment of transcription factor CEBP/a and the histone H3K4 methyltransferase MLL3/MLL4 complex. HOXA9 function at the de novo enhancer is distinct from its physiological role at distal enhancers during normal hematopoietic development. Genetic deletion of MLL3/4 specifically affects the active enhancer signatures at de novo enhancers and inhibits HOXA9/MEIS1-mediated leukemogenesis. Our study reveals a previously uncharacterized role of HOXA9 and the MLL3/4 complex in leukemogenesis and provide mechanistic insights in epigenetic deregulation during malignant transformation. Overall design: RNA-seq for untransformed myeloid progenitors (MP)

HOXA9 Reprograms the Enhancer Landscape to Promote Leukemogenesis.

Description
Sperm cells of seed plants have lost their motility and are transported by the vegetative pollen tube cell for fertilization. The extent to which sperm cells regulate their own transportation is a long-standing debate. By using the novel Arabidopsis double mutant drop1 drop2, we demonstrate here that sperm cells are only passive cargo and that the vegetative tube cell as a vehicle controls the entire journey. Overall design: the semi-in-vivo pollen tubes of wild type (WT) and drop mutant using single-cell RNA sequencing
Publication Title
Sperm cells are passive cargo of the pollen tube in plant fertilization.
