B(III) blood type may have higher hemoglobin levels, but stress affects this, and hair iron levels correlate with hemoglobin in some blood types.

In this case report, researchers describe a 13-year-old phenotypic female with 46,XY karyotype, previously misdiagnosed with androgen insensitivity syndrome, who was later identified to have 17-beta-hydroxysteroid dehydrogenase type 3 deficiency, underscoring the importance of genetic and hormonal tests for accurate diagnosis of sex development disorders.

In this study, the misshaped and hairy ear phenotype in mutant mice was linked to mis-expression of certain Hoxc genes due to a chromosomal inversion.

This study suggests that IGFBP-2 may play a role in basal cell carcinoma development by mediating epidermal progenitor cell expansion in hair follicles with activated Shh signaling.

This study suggests that the hairless gene encodes a nuclear factor important for hair follicle integrity, and its absence leads to hair follicle loss and defects in tissue development.

Focal palmoplantar callosities may help diagnose non-Herlitz junctional epidermolysis bullosa.

This study found that most pathogenic HR mutants associated with atrichia with papular lesions had abolished corepressor activity due to defective interactions with histone deacetylases.

This review discusses the hedgehog signaling pathway's role in cutaneous tumors and hematological disorders, highlighting its potential as a therapeutic target, but reports no new clinical findings.

This study found that monoclonal antibodies can identify specific immunological characteristics of hair fibrous proteins, with some antibodies reacting only with hair proteins and others showing broader activity with skin and epithelial cells.

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 benzodiazepine therapy in women with idiopathic hirsutism significantly increased sex hormone binding globulin and decreased dehydroepiandrosterone sulphate, but did not significantly affect hair growth.

This article highlights studies on cholesterol transporter proteins in hair cycles, epithelial-to-mesenchymal transition in cancer, ovarian hormone effects on cell polarity before implantation, and UV effects on rodent skin, without providing new clinical results.

In this study, researchers identified two distinct homozygous mutations in the KRT85 gene among consanguineous Pakistani families with pure hair and nail ectodermal dysplasia, highlighting variations in severity and potential impacts on the K85 protein function.

This article reviews the genetic mutations causing male pseudohermaphroditism from 17 beta-HSD-3 and 5 alpha-RD-2 deficiencies and reports no new clinical findings.

This study identified enzymes responsible for regulating androgen action in the human prostate, suggesting that inhibiting AKR1C2 or RL-HSD may have therapeutic potential in androgen insufficiency or benign prostatic hyperplasia, respectively.

This study created a humanized mouse model of hereditary vitamin D-resistant rickets that lacks alopecia, indicating the mutant receptor's potential to explore the syndrome's characteristics beyond vitamin D binding.

A new mutation in the HR gene causes hair loss in a specific family.

In this study, researchers observed that testicular 17β-hydroxysteroid dehydrogenase deficiency in an inbred Arab population in Israel leads to genital ambiguity at birth and progressive virilization after puberty.

This case report highlights two instances of suspected human herpesvirus 6 reactivation in patients with existing psychiatric disorders, underscoring the need for further research into the relationship between viral reactivation and psychiatric conditions.

In this study, a transgenic mouse model suggested that suppressing the expression of the HGPS mutation may reverse disease symptoms, including skin abnormalities, supporting the potential for treatment development.

This study found that betulinic acid inhibits hepatitis C virus replication by suppressing the NF-κB- and ERK1/2-mediated COX-2 pathway, suggesting its potential as a therapeutic supplement.

This study found that in transgenic mice overexpressing a mutant hairless gene, changes in its expression affected hair loss and regrowth, implicating the gene's role in hair follicle biology.

New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.

CaBP1 and 2 are necessary for maintaining calcium currents and hearing in inner ear cells.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

This review discusses the role of Hedgehog signaling in basal cell carcinoma development and highlights genetic mouse models and potential targeted therapies, but reports no new clinical results.

This study found that 3-hydroxypropionic acid improved the function of hair follicle cells under oxidative stress, suggesting potential as a treatment for stress-related hair loss.

TCHHL1 is a protein important for hair growth, found in hair follicles.

A specific gene mutation causes sparse, brittle hair in a family.
