This review summarizes what is known about Big tau and what is missing toward a better understanding of how expansion via inclusion of exon 4a modifies tau's structural and functional properties. Our purpose is to inspire future studies that could lead to novel therapeutic strategies to mitigate tau aggregation in neurodegenerative diseases.

There were no significant differences in time to blast transformation or time to next treatment depending on PHF6 gene status. According to the results of most studies published to date (SR), PHF6MUT has a prognostic role in MNs; our results are consistent in terms of clinical outcomes, but these marginal effects should be interpreted with caution in the context of existing prognostic models given the limitations of the small sample size.
In AML, it correlated with CD33 expression and inv(16)/t(16;16). In conclusion, mesothelin is rare in ALL but enriched in specific AML subtypes and not prognostic for survival.
Treatment with CTx-648, a KAT6A/KAT6B inhibitor, restored HSC function in Phf6R274XTg mice and prolonged the survival of leukemic Phf6R274XTg mice. These findings demonstrate a gain-of-function effect for truncated PHF6aa1-273 in driving leukemogenesis and highlight KAT6B as a promising therapeutic target in PHF6 truncation-associated hematologic malignancies.
The sequential acquisition of cooperating genetic lesions supports clonal evolution and highlights the need for molecular monitoring and novel therapeutic strategies. The authors have confirmed clinical trial registration is not needed for this submission.
Additionally, the depletion of PHF6 inhibited cell proliferation in both liver and pancreatic cancer cells. PHF6 expression was closely associated with the occurrence and development of many types of cancer, and it might promote cancer progression by inhibiting the function of the immune microenvironment, while knockout of PHF6 significantly inhibited the tumor cells proliferation.
In addition, patients with KMT2A mutation had shorter OS compared to those with wild type (HR, 4.605; P = 0.045), whereas other EMMs had no impact on prognosis in any type of ALL. Mutations in DNMT3A, IDH, PHF6 and KMT2A showed a significant prognostic effect in ALL or in its specific subtypes, which might contribute to risk stratification and treatment guidance in the management of ALL patients.
CNSI+ disease, especially in the consolidation/maintenance stage, was an independent poor prognostic factor in pediatric T-ALL. HSCT partially improved outcomes of children with T-ALL. Individualized treatment strategies containing a combination of immunotherapy and targeted therapy in addition to chemotherapy may improve patient outcomes.

Unlike related peptides classified as amyloids, the leads were found to be completely innocuous to neuroblastoma cell lines, even at high concentrations. Hexapeptides selected as leads are promising candidates for therapeutic purposes and can be used to develop molecules for biochemical diagnosis and probes for positron emission tomography (PET) imaging in the context of tauopathies, particularly Alzheimer's disease.
PLAG1 is a rare translocation partner of RUNX1 in AML, mistaken for classical t(8;21) on conventional karyotyping. The rare reported cases of PLAG1::RUNX1 suggest a distinctly poor prognosis, highlighting the importance of accurate diagnosis and the role of OGM in our practice.
This is the first case study characterizing the clinicopathological and genomic features of B/T MPAL harboring NUP98::BPTF fusion and providing insights into molecular pathogenesis. The authors have confirmed clinical trial registration is not needed for this submission.
