T-cell prolymphocytic leukemia (T-PLL) | MLL
T-prolymphocytic leukemia is a very rare, usually aggressive malignant disease of the lymphatic system. It accounts for approximately 2% of all mature lymphocytic leukemias in adults over 30 years of age and is described by WHO as a distinct entity within the mature T-cell and NK-cell neoplasms (WHO 2022).

Insights on the regulation of the MLL/SET1 family histone
In eukaryotes, histone H3K4 methylation by the MLL/SET1 family histone methyltransferases is enriched at transcription regulatory elements including gene promoters and enhancers. The level of H3K4 methylation is highly correlated with transcription activation ...
CircR-looping the leukemic translocations: The cause of MLL
Conn et al.1 identify circular RNAs (circRNAs) derived from mixed lineage leukemia (MLL) breakpoint cluster regions, demonstrating a causal role of circRNAs in MLL translocations. CircRNAs:DNA hybrids (circR-loops) trigger RNA polymerase pausing, driving oncogenic gene fusions via endogen …

Vaikka koulu alkaa, ekaluokkalaisen lapsuus jatkuu vielä pitkään. Itsenäistyminen tapahtuu vähitellen ja siinä pieni koululainen tarvitsee vanhemman tukea.
Leukemia Proto-Oncoprotein MLL Forms a SET1-Like …
MLL (for mixed-lineage leukemia) is a proto-oncogene that is mutated in a variety of human leukemias. Its product, a homolog of Drosophila melanogaster trithorax, displays intrinsic histone methyltransferase activity and functions genetically to maintain ...
SET1/MLL family of proteins: functions beyond histone methylation
The SET1 family of enzymes are well known for their involvement in the histone 3 lysine 4 (H3K4) methylation, a conserved trait of euchromatin associated with transcriptional activation. These methyltransferases are distinct, and involved in various biological ...
Molecular pathogenesis of disease progression in MLL
To clarify the molecular pathogenesis of progression in MLL -AML, we analyzed accumulation of genetic abnormalities in a mouse model of leukemia with human MLL / AF9 …
Molecular Basis of the Mixed Lineage Leukemia-Menin Interaction
Chromosomal translocations targeting the mixed lineage leukemia (MLL) gene result in MLL fusion proteins that are found in aggressive human acute leukemias. Disruption of MLL by such translocations leads to overexpression of Hox genes, resulting in a blockage of hematopoietic differentiation that ultimately leads to leukemia. Menin, which directly binds MLL, has been …
MLL-AF9 initiates transformation from fast-proliferating
Not all mutated cells become malignant, suggesting additional requirements for transformation. Here, the authors track blood progenitors from normal to malignancy driven by MLL-AF9, revealing a ...

The MLL recombinome of acute leukemias in 2017 | Leukemia
This study provides a comprehensive analysis of the MLL recombinome in acute leukemia and demonstrates that the establishment of patient-specific chromosomal fusion …
MLL2, Not MLL1, Plays a Major Role in Sustaining MLL-Rearranged Acute
Chen et al. report that wild-type MLL1 is dispensable for MLL fusion leukemia, but instead loss of MLL2 reduces the survival of leukemia cells from human cell lines and in a mouse model of MLL-AF9 AML. Combined loss of MLL1 and MLL2 further reduces leukemia cell viability.
The super elongation complex (SEC) and MLL in …
Transcriptional regulation at the level of elongation is vital for the control of gene expression and metazoan development. The mixed lineage leukemia (MLL) protein and its Drosophila homolog, Trithorax, which exist within COMPASS (complex of proteins ...
MLL fusion proteins and transcriptional control
The highly leukemogenic MLL fusion proteins have a unique mechanism of action. This review summarizes the current knowledge of how MLL fusions interact with the transcriptional machinery and it proposes a hypothesis how these proteins modify transcriptional control to act as transcriptional amplifiers causing runaway production of certain RNAs that …
MLL -Rearranged Acute Lymphoblastic Leukemia
This suggests that additional oncologic insults are needed for MLL -mediated leukemia transformation. MLL -rearranged ALL ( MLL -r-ALL) is characterized by …
XL MLL plus
XL MLL plus consists of an orange-labeled probe hybridizing proximal to the KMT2A gene region at 11q23.3 and a green-labeled probe hybridizing distal to the KMT2A gene region at 11q23.3.
Chromosomal translocations involving the MLL gene: …
A wide array of recurrent, non-random chromosomal translocations are associated with hematologic malignancies; experimental models have clearly demonstrated that many of these translocations are causal events during malignant transformation. Translocations ...
Mixed lineage leukemia: roles in human malignancies and
The increasing number of chromosomal rearrangements involving the human MLL gene, in combination with differences in clinical behavior and outcome for MLL-rearranged leukemia …

A Deep Dive Into MLL's History: From Its Inception To Today
Dive deep into MLL's History to uncover the league's inception, major milestones, and its lasting impact on the world of lacrosse. Explore how MLL has shaped the game from its early days to …
Why are so many MLL lysine methyltransferases required for …
The mixed lineage leukemia (MLL) family of proteins became known initially for the leukemia link of its founding member. Over the decades, the MLL family has been recognized as an important class of histone H3 lysine 4 (H3K4) methyltransferases that control ...
