Staging concept for aging management: Definition, mechanism, and coping strategies
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Cryo‐EM structure of ALC1 in an open conformation bound to a PARylated nucleosome
Reanalysis of a publicly available cryo‐EM dataset identifies a new conformation of the oncogenic chromatin remodeler ALC1/CHD1L bound to a PARylated nucleosome. This new structure reveals the position of the macro domain in the complex, and may help to understand the large conformational change leading to the activation of ALC1.Nucleosomes are the ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Mitokondriális eredetű nitrogén szabadgyökök és ATP-függő K-csatornák szerepe az organellum működésében = The involvement of mitochondrial-derived nitrogen radicals and mitoK-ATP channels in the regulation of organelle function [PDF]
Elsőként a mitoKATP csatornák alegységeit terveztük azonosítani humán szív mintákon. A kísérletek során megbizonyosodtunk afelől, hogy a korábban ilyen csatornáknak gondolt fehérjék nincsenek jelen megfelelő számban és formában a mitokondriális ...

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

The metalloproteinase ADAM17 promotes acute lung inflammatory responses during pancreatitis
Background and Purpose Acute pancreatitis (AP) is a multifactorial upper gastrointestinal inflammatory disorder that in severe cases (~20% of all AP) is associated with substantial morbidity and mortality, the latter coincident with multiorgan dysfunction, particularly acute lung injury (ALI).

In hepatocellular carcinoma, the 8q24.3 locus is frequently amplified and is associated with tumor‐specific overexpression of TONSL. TONSL promotes homologous recombination repair through RAD51, limits γH2AX accumulation and apoptosis, supports tumor growth, and its loss increases sensitivity to poly (ADP‐ribose) polymerase (PARP) inhibition.

Schematic pathway diagram illustrating the effects of JI‐CJ002 and dabrafenib on melanoma progression. The combination of JI‐CJ002 and dabrafenib is associated with reduced B7‐H3 expression and modulation of signaling pathways implicated in melanoma progression, including JAK2/STAT3, PI3K/AKT/mTOR, and Rb/E2F1.
