Summary
This study identified novel genetic factors for androgenetic alopecia (AGA), also known as patterned hair loss. New gene loci associated with female hair loss were discovered, offering insights into sex-specific causes of AGA.
Area of Science:
- Genetics
- Dermatology
- Molecular Biology
Background:
- Androgenetic alopecia (AGA) exhibits different pathological mechanisms in males and females.
- Genetic factors for male hair loss are well-studied, but female hair loss determinants remain unclear.
Purpose of the Study:
- To identify sex-specific genetic factors contributing to androgenetic alopecia (AGA).
- To investigate novel genetic loci associated with patterned hair loss in males and females.
Main Methods:
- Conducted three independent genome-wide association studies (GWASs) on approximately 1000 individuals (436 males, 568 females).
- Analyzed total, male-only, and female-only groups to identify significant single nucleotide polymorphisms (SNPs).
Main Results:
- Identified three novel loci: rs7814359 (TSNARE1), rs2163085 (FZD1), and rs4793158 (GJC1).
- rs2163085 showed significant association with AGA in females; rs4793158 was suggestively associated in females.
- FZD1 and GJC1 associations suggest potential influence of sex hormones like estrogen on female patterned hair loss (FPHL).
Conclusions:
- Findings contribute to understanding the sex-specific pathophysiology of androgenetic alopecia.
- Identified key genes (FZD1, GJC1) potentially involved in female hair loss mechanisms.

01:06Multipotency and Niche of Bulge Stem Cell
3.5K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

01:19X-linked Traits
54.4K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

02:19The Y Chromosome Determines Maleness
6.5K
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....

02:32X and Y Chromosomes
24.0K
Among mammals, the gender of an organism is determined by the sex chromosomes. Humans have two sex chromosomes, X and Y. Every human diploid cell has 22 pairs of autosomes and one pair of sex chromosomes. A human female has two X chromosomes, while a male has one X chromosome and one Y chromosome.
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...

02:57Meiosis vs. Mitosis
54.2K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

01:43Incomplete Dominance
22.1K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
