چکیده
Asymmetric small interfering RNA (asiRNA) that induces interference has been investigated for its therapeutic use in various tissues, including the skin. Androgenetic alopecia (AGA) is caused by a combination of genetic factors resulting sensitivity to dihydrotestosterone (DHT), which binds androgen receptor (AR) induce series biomolecular changes leading hair loss. This study aimed evaluate potential cell penetrating, AR-targeting asiRNA (cp-asiAR), was designed silence AR gene, AGA treatment. mouse models were generated stimulation with DHT, and ex vivo human scalp tissues also used. Cp-asiAR-mediated mRNA expression protein level assessed together phenotypic improvement We downstream signaling primary dermal papilla (DP) cells. Several cp-asiARs screened selecting optimal sequence using lines vitro. A cholesterol-conjugated, chemically modified cp-asiAR candidate optimized under passive uptake conditions Intradermal injection efficiently reduced levels models. Moreover, promoted growth DHT-induced In follicle culture, proportion telogen decreased, mean bulb diameter increased cp-asiAR-treated group. isolated DP cells, cells effectively downregulated cp-asiAR. Concurrently, attenuated increases interleukin-6, transforming factor-β1, dickkopf-1 levels. No significant toxicity observed after Effective downregulation prevention cycle achieved treatment, indicating as novel option AGA.

Comparison of the efficacy of valproic acid 8.3% and minoxidil 5% topical solutions in the treatment of androgenetic alopecia
Background and Aim: Hair loss is one of the most common problems among the skin and hair related diseases. Hair loss can lead to anxiety, depression, low self-esteem and dissatisfaction with appearance. Methods: Patients with androgenetic alopecia who met the eligibility criteria entered the study. Participants were asked to randomly apply a solution of valproic acid 8.3% or a solution of...
متن کاملTopical Melatonin for Treatment of Androgenetic Alopecia
BACKGROUND In the search for alternative agents to oral finasteride and topical minoxidil for the treatment of androgenetic alopecia (AGA), melatonin, a potent antioxidant and growth modulator, was identified as a promising candidate based on in vitro and in vivo studies. MATERIALS AND METHODS One pharmacodynamic study on topical application of melatonin and four clinical pre-post studies wer...
متن کاملNew Medical Treatment for Androgenetic Alopecia
Dihydrotestosterone(DHT) has played the pathogenic role in androgenetic alopecia. Patients with genetic deficiency of 5 alpha-reductase type II enzyme, which converts testosterone to DHT, do not have androgenic alopecia. The conversion of testosterone to DHT at hair follicles leads to miniaturization. In scalp biopsy, the tissue DHT level is significantly increased in balded area than non-balde...
متن کاملAndrogenetic alopecia and current methods of treatment.
Androgenetic alopecia (AGA) is a common dermatological condition affecting both men and women. In the case of men, up to 30% over the age of 30 and more than 50% over the age of 50 are affected. AGA also affects women although clinical signs are usually milder and associated with diffuse thinning of the scalp hair. AGA invariably causes serious psychological problems especially in women. By far...
