This study found that of the many ingredients advertised in shampoos as effective against hair loss, only caffeine, adenosine, placental proteins, and melatonin have limited clinical evidence supporting their efficacy, with most claimed active ingredients lacking any trial-based validation.

This study found no statistically significant relationship between androgenic alopecia and the PON1 ML55 and QR192 genetic polymorphisms, despite a higher frequency of the PON 55 L allele in patients.

This study reports that the asebia-2J mutation in mice affects sebaceous gland function and leads to hair follicle destruction, offering a model for human scarring alopecias.

In this study, the researchers identified a temperature-sensitive mutant in Arabidopsis thaliana, showing disrupted root hair formation and altered responses to plant hormone treatments at elevated temperatures.

This study discovered that a specific G to C mutation in the ornithine aminotransferase gene is linked to the retarded hair growth phenotype in mice and may serve as a model for human gyrate atrophy.

This study suggests that the ADIPOQ gene polymorphism may influence the risk of alopecia areata in Egyptians, with adiponectin levels potentially serving as a marker for hair loss severity.

This article previews a Journal of Investigative Dermatology quiz on diagnosing male androgenetic alopecia and offers no new research results.

This study found that the lack of expression and deletion of specific hair keratin genes on chromosome 7q36 in Hirosaki hairless rats suggests the crucial role of these genes in hair growth.

In this study, the SRD5A2 rs523349 polymorphism was significantly associated with an increased risk of miscarriage, particularly during the second trimester.

In this study, researchers found that the "U" allele of the Tru9I variant may be associated with low vitamin D levels and altered VDR gene activity in alopecia areata patients, while the "u" allele might have a protective role against developing the condition.

This study found that specific PITX2 gene variants are significantly associated with higher risk of androgenetic alopecia in males, highlighting important genetic and environmental interactions influencing its development.

This review summarizes recent genetic research on hidradenitis suppurativa, highlighting potential therapeutic targets and genetic mutations, but reports no new clinical findings.

In this study, researchers found that the AIRE G961C variant is a significant risk factor for severe alopecia areata and early-onset cases, particularly in patients with alopecia universalis.

This study reports that a new nude allele, nu(StL), encodes a truncated Whn transcription factor affecting T-cell development and keratin gene expression, with notable differences from the original Whn(nu) mutation.

This study found that the MTHFR gene C677T mutation appears to be a susceptibility factor for alopecia areata in the Turkish population.

In this study, the AA genotype of C2 polymorphism was more frequently observed in Chinese patients with systemic lupus erythematosus than controls, indicating it may be a risk factor for the disease.

This meta-analysis found that the rs2476601 SNP of the PTPN22 gene is significantly associated with reduced susceptibility to alopecia areata, with carriers of the C-allele and CC-genotype having a lower risk.

In this study, significant associations were observed between specific genetic polymorphisms in BDNF and CRH-R1 and the occurrence of vitiligo, along with differing serum levels of neurotransmitters between vitiligo patients and healthy controls.

In this study, single nucleotide polymorphisms in the RAB5B gene were linked to an increased risk of polycystic ovary syndrome and associated with specific microRNA binding sites.

This study found that genetic variants in the goat KRTAP22-2 gene are associated with the mean fiber diameter of cashmere in Longdong Cashmere goats, suggesting these variants could serve as molecular markers for improving cashmere traits.

In this study, researchers identified four novel variants in the FGF5 gene associated with the long-haired phenotype in dogs, suggesting additional unexplored genetic factors contribute to this trait beyond the known Lh1-Lh5 alleles.

This study found that genetic predictions of male pattern baldness from European populations do not generalize well to African populations, highlighting significant differences in genetic architecture between them.

In this study, researchers found that specific genetic variations at loci rs1160312, rs6113491, and rs1041668 are independent risk factors for androgenetic alopecia in men, and these risks can be influenced by diet.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This study found that the Siberian sunshine tabby coat modification is associated with a specific CORIN gene variant, suggesting a genetic basis for this golden phenotype in cats.

This review examines genetic variation in the ovine KRTAP1.1 gene and its potential impact on wool quality, reporting no new findings but suggesting opportunities for developing gene markers for wool and pelt traits.

This study found that IL-18 rs187238 and rs1946518 single nucleotide polymorphisms were associated with increased susceptibility to alopecia areata in a Turkish population.

The Thr1022Ala variant in the hairless gene is not a disease-causing mutation.

This study found that the AR-E211 A allele is associated with a lower risk of both metastatic prostate cancer and androgenetic alopecia in an Australian population.

This study found that overweight women with polycystic ovary syndrome carrying the HSD3B1 1245C allele had an increased presence of female pattern hair loss compared to those with the wild-type genotype.
