Epimedium protects against dyszoospermia in mice with Pex3 knockout by exerting antioxidant effects and regulating the expression level of P16

Cell Death and Disease, 2022
Oxidative stress (OS) is one of the primary factors leading to male infertility. Oral administration of antioxidants has thus far been found to significantly improve the quality of human sperm.

Genetic or pharmacological reduction of cholangiocyte senescence improves inflammation and fibrosis in the Mdr2-/- mouse

JHEP Reports, 2021
Summary: Background & Aims: Cholangiocyte senescence is important in the pathogenesis of primary sclerosing cholangitis (PSC). We found that CDKN2A (p16), a cyclin-dependent kinase inhibitor and mediator of senescence, was increased in ...

CDK4/MERCs/PINK1 Axis Drives PFOA/HFPO‐TA‐Induced Cardiac Senescence via Mitophagy Defect and cGAS‐STING Activation: In Vitro Amelioration by Cycloastragenol

Advanced Science, EarlyView.
The present study demonstrated that PFOA and HFPO‐TA exposure suppressed CDK4, disrupted MERCs and impaired PINK1/Parkin‐mediated mitophagy, thereby accelerating cardiac senescence, whereas CAG effectively reversed these pathological changes in vitro. Our findings identify CDK4 as a critical regulator bridging mitophagy defects and cardiac senescence ...

Type I Interferon Drives Dysfunction of a Distinct CD8+ HLA‐DRB1+ T Cell Subset in Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is characterized by type I interferon (IFN) signaling and adaptive immune dysregulation. We previously identified hypomethylation of HLA‐DRB1 and STAT1 in SLE CD8+ T cells, enabling aberrant IFN‐driven HLA‐DRB1 expression and expansion of a distinct CD8+ T cell subset. This study characterized CD8+ HLA‐DRB1+

Carrier‐free self‐assembled nanomedicine for combination‐therapy of acute myeloid leukemia

BMEMat, EarlyView.
CPDS combines drugs with three different mechanisms of action to achieve a multi‐mechanism combination therapy for AML by directly killing tumor cells and activating anti‐tumor immunity. Abstract As the main acute myeloid leukemia (AML) clinical treatment, the chemotherapy alone cannot meet the clinical therapeutic needs due to the high heterogeneity ...

Deletions and rearrangements of cyclin-dependent kinase 4 inhibitor gene p16 are associated with poor prognosis in B cell non-Hodgkin’s lymphomas [PDF]

Leukemia, 1997
In the present study we examined by Southern blot analysis the presence of deletions and rearrangements of the p16 tumor-suppressor gene in B cell non-Hodgkin's lymphomas (NHLs) in order to determine whether or not these changes can be related to a particular histological subtype and the different clinico-biological and prognostic characteristics of ...

Reversing brain aging: Targeting energy metabolism in endogenous neural stem cells

Interdisciplinary Medicine, EarlyView.
Mechanism of endogenous neural stem cells (eNSCs) energy metabolism disorder leading to brain aging and targeted eNSCs intervention strategies (By biorender). The disorder of energy metabolism of eNSCs can lead to their resting and aging, and eventually lead to brain aging.

Current view of the inhibitor protein cyclin-dependent kinase р16, р27 and their role in the cell cycle

Кубанский научный медицинский вестник, 2016
Violations of the cell cycle have their own characteristics in the skin lesions. The greatest attention is paid to the research of cancers, whereas benign tumors of the skin insufficiently studied.

Integrative Omics Reveal Female‐Specific Benefits of p16+ Cell Clearance in Aging Mice

Advanced Science
Aging is marked by the accumulation of cells expressing the cyclin‐dependent kinase inhibitor p16Ink4a. These p16⁺ cells, largely senescent, contribute to inflammation and tissue dysfunction. While eliminating p16⁺ cells improves healthspan, sex‐specific
