In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

In this study, the novel ASAXA-μCT imaging method identified that the shrinkage of sweat glands with aging causes dermal defects, reducing skin elasticity and contributing to wrinkling and sagging.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.

This study found that Bone morphogenetic proteins (BMPs) play a crucial role in dermal papilla cells' ability to induce hair follicle stem cell differentiation, and that androgens may impair this process by downregulating BMPs.

This study concluded that the expression of clock genes, specifically BMAL1, in hair follicles is linked to circadian rhythm, and BMAL1 regulates hair growth.

This study suggests a connection between the unfolded protein response and upregulation of NKG2D ligands in stressed hair follicles, highlighting a potential role of PRDX5 in alopecia areata pathogenesis.

This review summarizes the recent advances in molecular mechanisms influencing tissue sensitivity to glucocorticoids, emphasizing novel mutations and new information on the glucocorticoid receptor's circadian rhythm and ligand-induced repression, but reports no new results.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

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.

In a laboratory setting, this study found that Biotrinine® dry extract activated hair follicle growth pathways and increased certain growth factor secretions in human dermal papilla cells, suggesting potential benefits for treating chronic hair loss.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

This study reports that in a rat model of myocardial infarction, Zn-Cu ion sequential therapy improved cardiac function and cardiomyocyte metabolic activity by precisely regulating ion concentrations and maintaining elevated levels of the Per2 protein, important for cellular repair.

This study found that thyroxine modulates peripheral molecular clock gene expression in human hair follicles, which may have implications for treating clock-related diseases in patients with thyroid dysfunction.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

This study found that Phytochrome A is crucial for regulating central metabolism and the transition to mature seedling proteomes in tomato seedlings grown under far-red light.

This research focused on understanding how radiotherapy affects mitochondrial function and signaling pathways in metastatic breast cancer cells, aiming to clarify its roles in cell survival, apoptosis, and metastatic progression, but the results are not reported in the abstract.

This study found that extracting RNA from equine hair follicles can effectively identify 24-hour oscillations of specific circadian clock genes, offering a valuable non-invasive method to evaluate the equine circadian clock.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

This study found that leukocytes and beard hair follicle cells have an endogenous circadian clock, with PER1 and PER3 expression possibly serving as biomarkers for assessing individual biological clock traits.

This study suggests that miR-486 may protect against alopecia areata by maintaining hair follicle immune privilege and modulating expression of immune-related genes.

This study observed that Ginseng and Albizia extracts, when used together, protected human dermal papilla cells from oxidative stress-induced senescence, and inhibited genes that suppress hair growth, indicating their potential in preventing age-related hair density reduction.

This study suggests that mitochondrial dysfunction might contribute to the pathogenesis of Lichen planopilaris by triggering a metabolic shift that leads to chronic inflammation and hair follicle damage.

This study found that hyaluronic acid increased the size and cell proliferation of mixed aggregates in a 3D culture model, indicating its role in human hair follicle germ-like structure formation without enhancing dermal papilla cell markers.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

HEV light can harm or help skin and scalp, so safe exposure guidelines are needed.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This study found that the circadian clock regulates the activation and heterogeneity of hair follicle bulge stem cells, affecting tissue homeostasis and tumorigenesis risk in mouse skin.
