Did you mean Cell Cycle Arrest?

Glossary Cell Cycle Arrest

process that halts cell division to repair damage or stress

Cell cycle arrest is a mechanism that stops the progression of the cell cycle, preventing cells from dividing. This can occur in response to DNA damage, lack of nutrients, or other stress signals, allowing the cell time to repair itself or, if the damage is too severe, to initiate programmed cell death (apoptosis). This process is crucial for maintaining genetic stability and preventing the proliferation of damaged cells, which can lead to diseases like cancer.

Characterization of Cell Cycle Arrest and Terminal Differentiation in a Maximally Proliferative Human Epithelial Tissue: Lessons from the Human Hair Follicle Matrix

research Characterisation of cell cycle arrest and terminal differentiation in a maximally proliferative human epithelial tissue: Lessons from the human hair follicle matrix

30 citations , April 2017 in “European Journal of Cell Biology”

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

4-O-Methylhonokiol Protects HaCaT Cells from TGF-β1-Induced Cell Cycle Arrest by Regulating Canonical and Non-Canonical Pathways of TGF-β Signaling

research 4-O-Methylhonokiol Protects HaCaT Cells from TGF-β1-Induced Cell Cycle Arrest by Regulating Canonical and Non-Canonical Pathways of TGF-β Signaling

5 citations , February 2017 in “Biomolecules & Therapeutics”

The authors reported that 4-O-methylhonokiol decreased TGF-β1-induced cell cycle arrest and oxidative stress markers in human keratinocyte cells, suggesting a potential protective role in TGF-β1-mediated cell cycle regulation.

Maternal Androgen Excess Inhibits Fetal Cardiomyocyte Proliferation Through RB-Mediated Cell Cycle Arrest and Induces Cardiac Hypertrophy in Adulthood

research Maternal androgen excess inhibits fetal cardiomyocytes proliferation through RB-mediated cell cycle arrest and induces cardiac hypertrophy in adulthood

2 citations , August 2023 in “Journal of Endocrinological Investigation”

In this study, researchers found that pregnant mice exposed to excessive androgen led to thinner ventricular walls and cardiac hypertrophy in offspring, suggesting that prenatal androgen exposure adversely affects cardiac health through reduced cardiomyocyte proliferation.

research 549 Temporary cell cycle arrest in human scalp hair follicles and their epithelial stem cells by ALRN-6924: A novel strategy to selectively protect p53-wildtype cells against paclitaxel-induced alopecia

1 citations , November 2022 in “Journal of Investigative Dermatology”

This study found that ALRN-6924, a clinical-stage dual inhibitor, can selectively protect human scalp hair follicles from paclitaxel-induced toxicity and damage by inducing transient cell cycle arrest in healthy cells without affecting cancer cells, potentially reducing chemotherapy-induced alopecia.

research Intensive stress impedes hair follicle growth through triggering cell cycle arrest of hair follicle stem cells

March 2025 in “The FASEB Journal”

In this study on mice, intensive stress through methods like resiniferatoxin injections and physical restraint was found to inhibit hair follicle growth, with the mechanism involving the sympathetic nervous system and the cAMP signaling pathway in hair follicle stem cells.

community Japan-led "Third Cell" Discovery: Is this the missing link for full follicle regeneration?

in Technology 132 upvotes 6 months ago

A new "third cell" discovery in Japan could be key to fully regenerating hair follicles, with human trials possibly starting in 2027-2028. AI is expected to accelerate medical discoveries, potentially leading to a hair loss cure within a few years.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

community PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

7 months ago

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

community Fats on your Head to Stop Hair Loss?

140 upvotes 2 years ago

The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

community Will PP405 need to be used indefinitely, like minoxidil?

31 upvotes 10 months ago

PP405 may not need daily use like minoxidil, but finasteride might still be needed to maintain hair regrowth. PP405 reawakens dormant hair follicles, potentially offering a long-term solution, though not a permanent cure.
