January 2012 in “Current Topics in Microbiology and Immunology” This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.
1 citations
,
April 2006 in “International Journal of Oncology” In this study, lysocellin induced G1 phase arrest in human osteosarcoma cells, but diminished the cytotoxic efficacy of etoposide, while its derivative alopestatin may reduce etoposide-induced alopecia in a rat model.
March 2026 in “Aging Research” This review provides a comprehensive synthesis of skin aging research, highlighting the interplay of genetic and environmental factors, cellular mechanisms, and advances in diagnostic and therapeutic strategies, while also addressing current debates and future directions in the anti-aging field.
This report details a case of hair, nail, and pigmentary disorders occurring 10 months after starting abemaciclib for metastatic breast cancer, highlighting that cutaneous side effects, although less frequent, can lead to discontinuation in 25% of cases.
June 2024 in “Journal of Clinical Oncology” This study observed that dalpiciclib is associated with fewer adverse events like diarrhea and hepatotoxicity compared to other CDK4/6 inhibitors, potentially offering better patient-perceived safety and quality of life.
