GlossaryPost-transcriptional regulation

control of gene expression after RNA is made from DNA

Post-transcriptional regulation refers to the control of gene expression after the DNA has been transcribed into RNA but before it is translated into proteins. This process includes modifications like RNA splicing, editing, transport, and stability, which ultimately influence how much protein is produced from a gene. For example, in hair biology, post-transcriptional regulation can affect the production of proteins involved in hair growth and maintenance, potentially impacting conditions like alopecia.

community Adrogens and Covid-19

in Treatment 7 upvotes 5 years ago

The possible increased risk of severe Covid-19 cases in men due to higher androgen levels, and how taking medications such as finasteride, dutasteride, spironolactone, enzalutamide, or canabidiol might help mitigate the severity of the disease.

community New Research- Creatine Increasing Scalp DHT Without Corresponding Serum DHT Increase

in Research/Science 124 upvotes 2 years ago

Creatine may increase scalp DHT without affecting serum DHT, potentially speeding up male pattern baldness (MPB) for those genetically prone. Treatments mentioned include Minoxidil, finasteride, and RU58841.

community Fats on your Head to Stop Hair Loss?

in Research/Science 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 TWIST-1 and the cure: Is it really that easy?

in Research/Science 283 upvotes 4 years ago

TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.

community HLT Megathread on HMI-115 (key takeaways in comments)

in Research/Science 39 upvotes 3 years ago

HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.
