Genetic Profiling Reveals the Distinctions Among MTX‐Associated DLBCL, EBV‐Positive Mucocutaneous Ulcer, and EBV + DLBCL

open access: yesCancer Science, EarlyView.
EBV‐ MTX‐DLBCL shows higher driver gene mutation rates and worse outcomes after MTX discontinuation compared to EBV+ MTX‐DLBCL. IDD‐LPDs have lower mutation rates in genes related to clonal hematopoiesis (TET2/DNMT3A) and immune evasion (CD58) compared to EBV + DLBCL. ABSTRACT The WHO recently changed the outline of immunodeficiency/dysregulation (IDD)‐

TRAPPC2l Participates in Male Germ Cell Development by Regulating Cell Division

open access: yesCell Proliferation, EarlyView.
Trappc2l is crucial for maintaining the quiescent state of male gonocytes. In the absence of Trappc2l, the quiescent state of gonocytes is disrupted, leading to premature and abnormal initiation of meiosis, which consequently results in subsequent abnormalities in sperm development. ABSTRACT TRAPPC2L is a core subunit of the Transport Protein Particle (

Testis‐Specific PDHA2 Is Required for Proper Meiotic Recombination and Chromosome Organisation During Spermatogenesis

open access: yesCell Proliferation, EarlyView.
PDHA2, a testis‐specific subunit of pyruvate dehydrogenase, is required for the conversion of pyruvate to acetyl‐CoA. Its absence results in decreased acetyl‐CoA and precursors for metabolites and energy during spermatogenesis. This results in decreased histone acetylation, defective chromosome structure and moderately reduced crossovers, ultimately ...

Hypertranscription of rDNA Responsible for Nucleolar Remodelling is a Doorman for Acquiring Pluripotency

open access: yesCell Proliferation, EarlyView.
Active nucleoli have the capability to release perinuclear heterochromatin, which is a novel event of iPSC reprogramming. ABSTRACT Ribosome biogenesis occurs within the nucleolus, with the initial step being the transcription of ribosomal DNA (rDNA). Although rDNA transcription is limited in somatic cells, it is more active in stem cells. Nevertheless,

Mesenchymal stem cell‐mediated mitochondrial transfer regulates the fate of B lymphocytes

open access: yesEuropean Journal of Clinical Investigation, EarlyView.
Mesenchymal stem cells (MSCs) modulate immune responses by transferring mitochondria to immune cells, including B lymphocytes. This study demonstrates that mitochondrial transfer to CD19+ cells is linked to reactive oxygen species levels, mitophagy and activation. Mitochondria acquisition enhances B cell viability and proliferation while downregulating

Stress‐inducible phosphoprotein 1 (Sti1/Stip1/Hop) sequesters misfolded proteins during stress

open access: yesThe FEBS Journal, EarlyView.
Stress‐inducible phosphoprotein 1 (Sti1/Stip1/Hop) is a major co‐chaperone to both Hsp90 and Hsp70. We find that misbalanced expression of Sti1 in yeast and mammalian cells causes severe growth defects. Deletion of STI1 causes an accumulation of soluble misfolded ubiquitinated proteins and a strong activation of the heat shock response.

Saccharomyces cerevisiae Mub1, a substrate adaptor of E3 ubiquitin ligase Ubr2, modulates sensitivity to cell wall stressors through multiple transcription factors

open access: yesThe FEBS Journal, EarlyView.
We show that Mub1 links cell wall robustness with the ubiquitin‐proteasome system. As an adaptor protein of the E3 ubiquitin ligase Ubr2, it facilitates the ubiquitination of various transcription factors, including Mcm1 and Swi4. Yeasts evolved a complex regulatory programme to build and maintain their cell wall, the primary structure through which ...
