research The legacy of Bruce Ames and mitochondrial DNA mutagenicity: integrating oxidative stress, aging, and modern perspectives

October 2025 in “Frontiers in Molecular Biosciences”

This source critically examines Bruce Ames's influential contributions to biochemistry, particularly his theories on oxidative stress and mitochondrial DNA damage in aging, while acknowledging current challenges to his work and highlighting his lasting impact on the fields of mutagen screening and public health.

research Melatonin as a major skin protectant: from free radical scavenging to DNA damage repair

160 citations , July 2008 in “Experimental dermatology”

This review discusses the protective effects and mechanisms of melatonin in skin and suggests potential therapeutic applications in cutaneous medicine, reporting no new clinical findings.

research Promotion of homology-directed DNA repair by polyamines

47 citations , January 2019 in “Nature communications”

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

research Polarity signaling ensures epidermal homeostasis by coupling cellular mechanics and genomic integrity

38 citations , July 2019 in “Nature Communications”

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

research Integrated Analysis of Methylome and Transcriptome Changes Reveals the Underlying Regulatory Signatures Driving Curly Wool Transformation in Chinese Zhongwei Goats

39 citations , January 2020 in “Frontiers in Genetics”

community DNA test result is incredible !

in Technology 31 upvotes 7 months ago

The conversation discusses a personalized hair loss treatment plan based on DNA test results, recommending Minoxidil, Dutasteride, 17-alpha Estradiol, Cetirizine, and PRP sessions. The test identifies a high risk of hair loss due to DHT but a good response to Minoxidil, suggesting a tailored approach to treatment.

community Should you stop finasteride if you're trying to conceive?

40 upvotes 4 weeks ago

Stopping finasteride 3 to 6 months before trying to conceive may improve sperm quality and increase chances of conception. Many users reported successful pregnancies after pausing finasteride, with some switching to topical finasteride and oral minoxidil during this period.

community A Theory on Why Microneedling Works

175 upvotes 6 years ago

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community Red Light Therapy: Cheap Chinese LED caps are better than $3000 laser caps

in Research/Science 37 upvotes 1 year ago

Affordable 92-LED caps may be more effective for hair growth than expensive 270-laser caps due to higher power output and irradiance. The LED caps deliver more energy to the scalp, making them a cost-effective alternative for red light therapy.
