This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This symposium reported that DNA damage accumulation in aging stem cells affects genome integrity, highlighting novel mechanisms like Bmi1's role in DNA repair and the involvement of BATF in lymphoid differentiation.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that minoxidil stimulates the Kir6.2/SUR2 potassium channel, leading to tumor growth arrest in an ovarian cancer xenograft model by disrupting mitochondrial function and inducing cell death.
