Getting old through the blood. Circulating molecules in aging and senescence of cardiovascular regenerative cells [PDF]

open access: yes, 2017
Global aging is a hallmark of our century. The natural multifactorial process resulting in aging involves structural and functional changes, affecting molecules, cells, and tissues.

Oxidative stress, telomeres and cellular senescence: What non-drug interventions might break the link? [PDF]

open access: yes, 2020
Telomeres are higher order structures that cap and protect chromosome ends. Telomeric DNA naturally shortens during somatic cell division and as a result of oxidative stress.

Suppression of p16 alleviates the senescence-associated secretory phenotype [PDF]

open access: yes, 2020
AbstractOncogene induced senescence (OIS) is characterized by increased expression of the cell cycle inhibitor p16, leading to a hallmark cell cycle arrest. Suppression of p16 in this context drives proliferation, senescence bypass, and contributes to tumorigenesis.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Cellular Senescence as a Targetable Risk Factor for Cardiovascular Diseases

open access: yesJACC: Basic to Translational Science
Summary: The prevalence of cardiovascular diseases markedly rises with age. Cellular senescence, a hallmark of aging, is characterized by irreversible cell cycle arrest and the manifestation of a senescence-associated secretory phenotype, which has ...

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...

Investigating the role of Hedgehog/GLI1 signaling in glioblastoma cell response to temozolomide. [PDF]

open access: yes, 2018
Resistance to chemotherapy substantially hinders successful glioblastoma (GBM) treatment, contributing to an almost 100% mortality rate. Resistance to the frontline chemotherapy, temozolomide (TMZ), arises from numerous signaling pathways that are ...

Senescence-Associated Secretory Phenotype (SASP) in Diabetes

open access: yesJournal of Pharma Insights and Research
Cellular senescence represents a critical biological process characterized by permanent cell cycle arrest and distinct metabolic alterations. The senescence-associated secretory phenotype (SASP) has emerged as a fundamental mediator linking cellular aging to various pathological conditions, including diabetes mellitus.
