Glossary Chromosome

long DNA molecule with part or all of genetic material

A chromosome is a long, thread-like structure made of DNA and proteins that carries genetic information. In humans, each cell typically contains 46 chromosomes, which are organized into 23 pairs. These structures are crucial for the proper distribution of genetic material during cell division and play a key role in heredity and the functioning of an organism.

research A group of type I keratin genes on human chromosome 17: characterization and expression.

141 citations , February 1988 in “Molecular and Cellular Biology”

This study found that despite strong homology between two K16 genes, only one encoded a functional protein that assembled into keratin filaments in epithelial cells, possibly due to promoter strength differences.

community Chromosome 20’s balding effects and why fin likely isn’t working for some.

in Treatment 96 upvotes 1 year ago

Finasteride is effective for DHT/AR-driven hair loss but not for chromosome 20-driven cases, where treatments like minoxidil, prostaglandin analogs, and low-level laser therapy may be more beneficial. Genetic testing can help determine the underlying cause of hair loss to tailor treatment effectively.

community Why Is No One Talking About Chromosome 20?

in Chat 32 upvotes 1 year ago

Some hair loss may be linked to chromosome 20, which isn't affected by DHT blockers like finasteride. Treatments like minoxidil, microneedling, and genetic testing are suggested, but their effectiveness for this type of hair loss is uncertain.

community IVF process on Finasteride and effects of stopping finasteride.

138 upvotes 9 months ago

Concerns about finasteride affecting sperm quality and embryo abnormalities during IVF. The user plans to stop finasteride for 6 months and use minoxidil, microneedling, a red light cap, and saw palmetto shampoo to manage hair loss.

community Female, 30, PCOS diagnosis, MPB Norwood 2. Endo refuses to give anything other than Spironolactone. Feel like I’m at my wit’s end here.

55 upvotes 2 years ago

A 30-year-old female with PCOS and male pattern baldness is frustrated with her endocrinologist's recommendation of only Spironolactone and minoxidil, feeling that dutasteride, finasteride, and progesterone would be more effective. Other users suggest various online sources for treatments, warn against self-medicating due to potential risks, and recommend seeking a specialized endocrinologist or considering additional treatments like Inositol, Berberine, and dermaneedling.

community Dutasteride users- when and how did it go for you?

in Finasteride/Dutasteride 58 upvotes 9 months ago

Dutasteride can stabilize or improve hair loss but may cause side effects like depression and anxiety. Users often switch from finasteride to dutasteride for stronger results, with varied experiences in shedding and regrowth.
