This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

This review summarizes research on the synthesis and gene regulation of keratin in hair follicles, noting that coordinated gene activity is essential for hair follicle differentiation and normal hair growth, with gene clusters suggesting possible global regulatory domains.

This study found that DNA methylation and histone modification status were altered in peripheral blood mononuclear cells of patients with alopecia areata, suggesting these changes may contribute to the disease's pathological immune responses.

In this study, researchers found that contrary to expectations, keratin 10 domains did not reduce cell proliferation and instead increased tumor development in genetically modified mice.

This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

In this study, researchers found that deleting the Bmi1 gene in murine melanocytes caused premature hair greying and loss of melanocyte lineage cells, highlighting BMI1's role in protecting melanocyte stem cells from stress and oxidative damage.

This study suggests that the activation of box A in mesenchymal cell models may enhance stem cell properties, increasing the expression of stemness markers like OCT4, NANOG, and SOX2.

This study found that HDAC6 plays a crucial role in regulating primordial follicle activation, with its overexpression delaying activation and preserving fertility by reducing NGF levels.

Keratin filaments are crucial for cell structure and protection, with ongoing discoveries about their genes and functions.

This study proposes a model suggesting that the ratio of keratin 15 to keratin 14 in epidermal keratinocytes promotes a progenitor state and opposes differentiation, based on insights from both cell culture and transgenic mouse models.

This study identified complex regulatory elements and interactions involving the Hr gene and HR protein that are crucial for hair follicle formation and cycling in mammals.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This study identified 92 novel regulators of melanogenesis, highlighting Aldehyde dehydrogenase 1A1 as a potential target for developing new treatments for hyperpigmentation disorders like melasma.

In this study, silencing BMAL1 and PER1 genes increased melanogenic activity in follicular and epidermal melanocytes, suggesting that peripheral circadian clocks may regulate melanin pigmentation.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This review discusses the complex hormonal control of keratin expression in skin and its potential implications for treating skin and hair disorders, but reports no new clinical results.

This study suggests that activating AMPK to phosphorylate ZDHHC13 may enhance MC1R function and reduce melanoma risk in individuals with red hair.

In this study, researchers found that AP-2α and AP-2β are critical for maintaining epidermal homeostasis in adult skin, with their combined loss leading to severe skin and hair abnormalities and early skin inflammation due to impaired keratinocyte differentiation.

Protein ubiquitylation is crucial for controlling stem cell functions and could be targeted for cancer treatment.

This study found that the RNA helicase DDX6 is essential for maintaining self-renewal in epidermal progenitor cells by promoting the translation of proliferation regulators and degrading differentiation-inducing mRNAs.

This study found that BMP-2 activates Dlx3 gene transcription in murine keratinocytes by binding with Smad1/Smad4, suggesting a mechanism for BMP signaling's role in skin and hair follicle regulation.

This study found that human centromeric regions exhibit large-scale haplotypes with significant diversity, including entire Neanderthal haplotypes, which may affect chromosome transmission.

This study identified ALDH1A1 as a regulator of melanogenesis and suggests its inhibition, through agents like cyanamide, may be a promising therapeutic approach for treating hyperpigmentation disorders such as melasma.

In this study, researchers found that the transcriptional program regulated by PRC2 is not necessary for maintaining hair follicle stem cell quiescence and hair regeneration in vivo.

Some cells may slow melanoma growth, a protein could affect skin pigmentation, a gene-silencing method might treat hair defects, skin bacteria changes likely result from eczema, and a defensin protein could help treat multiple sclerosis.

The FTO gene hinders stem cells in hair follicles from becoming pigment cells.

This study found that transgenic mice with keratinocyte-specific overexpression of CtBP1 exhibited abnormal hair follicle development, suggesting CtBP1 may play a pathogenic role in hair morphogenesis.

In this study, transgenic mice expressing a truncated form of latent transforming growth factor-β-binding protein exhibited altered hair cycles due to increased active transforming growth factor-β, impacting keratinocyte proliferation and hair cycle phases.
