The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Augmin-dependent microtubule self-organization drives kinetochore fiber maturation in mammals

Cell Reports, 2022
Summary: Chromosome segregation in mammals relies on the maturation of a thick bundle of kinetochore-attached microtubules known as k-fiber. How k-fibers mature from initial kinetochore microtubule attachments remains a fundamental question. By combining

Non‐canonical nitric oxide signalling and DNA methylation: Inflammation induced epigenetic alterations and potential drug targets

British Journal of Pharmacology, EarlyView.
Abstract DNA methylation controls DNA accessibility to transcription factors and other regulatory proteins, thereby affecting gene expression and hence cellular identity and function. As epigenetic modifications control the transcriptome, epigenetic dysfunction is strongly associated with pathological conditions and ageing.

Distribution of lifetimes of kinetochore-microtubule attachments: interplay of energy landscape, molecular motors and microtubule (de-)polymerization

, 2014
Before a cell divides into two daughter cells, chromosomes are replicated resulting in two sister chromosomes embracing each other. Each sister chromosome is bound to a separate proteinous structure, called kinetochore (kt), that captures the tip of a ...

PSMD14/E2F1 Axis‐Mediated CENPF Promotes the Metastasis of Triple‐Negative Breast Cancer Through Inhibiting Ferroptosis

Cancer Science, EarlyView.
PSMD14/E2F1 axis‐mediated CENPF could promote the metastasis of BC through inhibiting arachidonic acid metabolism‐induced ferroptosis. This research might bring novel insights on discovering methods in alleviating tumor metastasis in BC. ABSTRACT The metastasis of triple‐negative breast cancer (TNBC) usually contributes to the failure of treatment ...

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

Cancer 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

Cell 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 (
