Glossary G2 phase

part of cell cycle ensuring DNA is ready for division

The G2 phase is a part of the cell cycle that occurs after DNA replication (S phase) and before cell division (mitosis). During this phase, the cell checks for DNA damage and ensures all the genetic material has been accurately replicated, while also producing proteins and organelles needed for cell division. This phase is crucial for maintaining genetic stability and preparing the cell for successful division.

research 12-Chloracetyl-PPD, a novel dammarane derivative, shows anti-cancer activity via delay the progression of cell cycle G2/M phase and reactive oxygen species-mediate cell apoptosis

18 citations , December 2016 in “European journal of pharmacology”

In this study, 12-Chloracetyl-PPD showed anti-cancer activity by inhibiting cancer cell viability and inducing apoptosis through reactive oxygen species production without harming normal cells.

research G2 stem cells orchestrate time-directed, long-range coordination of calcium signaling during skin epidermal regeneration

4 citations , October 2021 in “bioRxiv (Cold Spring Harbor Laboratory)”

This study found that epidermal stem cells in live mice exhibit coordinated intercellular Ca 2+ signaling governed by G2 cycling stem cells and mediated by Connexin43, essential for tissue-wide communication during regeneration.

research Implication of microRNA regulation in para-phenylenediamine-induced cell death and senescence in normal human hair dermal papilla cells

8 citations , March 2015 in “Molecular Medicine Reports”

This study found that para-phenylenediamine induces cytotoxic effects in normal human hair dermal papilla cells by altering microRNA expression and causing cell death, cell cycle arrest, and oxidative stress.

research The local hypothalamic–pituitary–adrenal axis in cultured human dermal papilla cells

9 citations , June 2020 in “BMC Molecular and Cell Biology”

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

research Myristoleic Acid Promotes Anagen Signaling by Autophagy through Activating Wnt/β-Catenin and ERK Pathways in Dermal Papilla Cells

8 citations , February 2021 in “Biomolecules & therapeutics”

This study found that myristoleic acid promotes dermal papilla cell proliferation and anagen signaling through autophagy, cell cycle progression, and activation of the Wnt/β-catenin and ERK pathways.
