Introduction: The BRG1/BRM associated factors (BAF) complex is a chromatin remodeling SWI/SNF which is mutated in 20% of cancers. This complex has many interchangeable subunits which may have oncogenic or tumor suppressor activity in a context-dependent manner. The BAF complex is mutated in 35-50% of metastatic prostate cancer (PC); however, its role in advanced disease is unclear. This review attempts to consolidate current knowledge of the BAF complex in PC and explore potential therapeutic approaches.
Areas Covered: This review covers the known roles of some BAF subunits, their alterations, and the models which best explain their mechanisms in driving PC. Following this, the authors provide their expert perspective on how this complex could be targeted in the future with a personalized medicine approach.
Expert Opinion: Personalized medicine would allow for patient stratification to exploit synthetic lethal strategies in targeting a mutated BAF complex as shown experimentally in other cancers. BAF dependency can also be targeted in patients stratified for other molecular markers such as BRG1 targeting in phosphatase and tensin homolog (PTEN) deficient PC.

PIKFYVE deficiency induces vacuole-like cataract via perturbing late endosome homeostasis.

Phosphoinositide kinase, FYVE-type zinc finger containing (PIKFYVE) was recently identified as a causative gene for cataract. Pikfyve phosphatidylinositol phosphate kinase domain-deficient (pikfyve) zebrafish lens and PIKFYVE-inhibited human lens epithelial cells developed vacuoles, colocalized with late endosome marker RAB7. In this study, the pikfyvezebrafish with vacuole-like cataract underwent transcriptomic and proteomic analyses to explore the underlying mechanisms of vacuole formation.

Huntington's Disease (HD), a progressive neurodegenerative disorder with no disease-modifying therapies, is caused by a CAG repeat expansion in the HD gene encoding polyglutamine-expanded huntingtin (HTT) protein. Mechanisms of HD cellular pathogenesis and cellular functions of the normal and mutant HTT proteins are still not completely understood. HTT protein has numerous interaction partners, and it likely provides a scaffold for assembly of multiprotein complexes many of which may be altered in HD.

The mechanism by which DNA-damage affects self-renewal and pluripotency remains unclear. DNA damage and repair mechanisms have been largely elucidated in mutated cancer cells or simple eukaryotes, making valid interpretations on early development difficult. Here we show the impact of ionizing irradiation on the maintenance and early differentiation of mouse embryonic stem cells (ESCs).

Article Synopsis
- The vacuolar-type H-ATPase (V-ATPase) is essential for regulating pH levels in cells, and its activity is influenced by various pathways, particularly phosphorylation, which is not well understood.
- In response to starvation, the kinase ABL1 phosphorylates a specific subunit of V-ATPase, ATP6V1B2, enhancing its assembly and function.
- ABL1 inhibition disrupts V-ATPase assembly and lysosomal acidification, leading to impaired autophagy processes, including the degradation of damaged cellular components, highlighting ABL1's key role in cellular stress responses.

The switch/sucrose non-fermentable (SWI/SNF) chromatin remodeling complexes (also referred to as BAF complexes) are composed of multiple subunits, which regulate the nucleosome translocation and chromatin accessibility. In recent years, significant advancements have been made in understanding mutated genes encoding subunits of the SWI/SNF complexes in cancer biology. Nevertheless, the role of SWI/SNF complexes in immune response and inflammatory diseases continues to attract significant attention.
