This study explored how root hairs integrate opposing growth signals but did not report new conclusive findings on the activation of known molecular players in polar growth.

This review discusses the potential of Ziziphus species and its extracted oil as new therapeutic agents in drug development and highlights the need for further studies to fully exploit this species for human health benefits.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

In this study, researchers linked defects in U2HR, an inhibitory region in the HR gene, to Marie Unna hereditary hypotrichosis, suggesting a mechanism for controlling hair growth and addressing hair loss.

This article discusses the cutaneous side effects of various chemotherapeutic agents but reports no new clinical results; the authors emphasize the importance of dermatologists recognizing drug-induced skin reactions to better patient care.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This article reviews the current ACR classification criteria for systemic lupus erythematosus, highlighting their dermatologic limitations, and proposes guidelines for a study to update these criteria.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study demonstrated that dominant mutations in mouse gasdermin A3 disrupt mitochondrial oxidative stress regulation, suggesting a gain-of-function effect on epidermal differentiation.

This review summarizes the dermoscopic structures associated with infectious and inflammatory skin conditions and hair disorders in children but reports no new clinical results.

This review discusses the progress and challenges in delivering CRISPR/Cas9 systems for in vivo genome editing, highlighting current methods and opportunities for future therapeutic applications.

This study identified novel genetic associations with skin phenotypes such as age-spots, freckles, and hair characteristics in Japanese women, providing insights into the genetic basis of these traits.

This study found no support for the idea that male-pattern baldness in female-to-male transsexuals indicates an increased risk of coronary heart disease through androgenic effects on classic risk factors.

This study found that the hairless gene in mice has a more extensive role in development than previously thought, as indicated by its expression in various tissues and associated abnormalities in hr/hr mutants.

This review discusses the physiological changes in the female body during pregnancy, relating them to hormonal shifts, and comments on treatment considerations, but it presents no new research findings.

This study found that miRNA expression profiles in follicular fluid are altered in women with PCOS, with certain miRNAs potentially useful for distinguishing patient subtypes and contributing to understanding PCOS heterogeneity.

This review discusses Chrousos syndrome, a rare condition caused by NR 3C1 gene mutations leading to glucocorticoid resistance, and reports no new clinical results; early identification and genetic testing are recommended for diagnosis.

This study found that women with early-onset androgenetic alopecia had higher aldosterone levels and blood pressure, suggesting a possible link to the increased prevalence of hypertension in this group.

This review summarizes the genetic studies on female pattern hair loss, highlighting the lack of clearly identified susceptibility loci and suggesting distinct aetiological differences from male pattern hair loss.

This study reports the development of the first rodent model for androgenetic alopecia, demonstrating that overexpression of androgen receptors in mice delays hair regeneration and can be used to test new treatments.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study found that men with Kennedy disease have a significantly lower risk of androgenetic alopecia, likely due to androgen receptor gene alterations from the disease's polyglutamine expansion.

This review synthesizes recent findings on the hair follicle stem cell niche and its complex interactions, exploring potential pathways for developing new hair growth therapies; it reports no new clinical results.

This study found that a genetic model using SNPs can predict early-onset male-pattern baldness with moderate accuracy, which may assist in decisions about interventions.
