This study found that p21 is much more highly expressed in normal melanocytes compared to melanoma cells, suggesting a potential target for preventing melanoma progression through cell cycle repair processes.

In this study, researchers found that using a 5-α reductase inhibitor may reduce inflammation-related cytokines associated with T-helper cell 1 and T-helper cell 2 in prostate tissues after surgery, but it did not affect those related to Th17 cells.

This study found that ornithine decarboxylase (ODC) may play a significant role in regulating human hair growth and hair cycle changes, as inhibiting ODC reduced follicular keratinocyte proliferation and human hair growth.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This study suggests that synthetic ceramides may promote hair growth by inducing proliferation of human dermal papilla cells through modulation of Wnt/β-catenin and BMP2/4 signaling pathways.

This study suggests that hair follicle mesenchymal stem cells may alleviate small intestinal ischaemia-reperfusion injury in rats by promoting angiogenesis, reducing apoptosis, and protecting intestinal mucosal function.

In this study, herbal extracts commonly used in traditional medicine were observed to significantly increase the proliferation of human dermal papilla cells, suggesting potential as alternative therapies for enhancing hair growth.

In this study, Salvia plebeia extract promoted hair growth by enhancing proliferation and anti-apoptotic effects in human dermal papilla cells and increased hair growth in treated mice.

This study found that platelet-rich plasma might support brain health by enhancing glial cell function and modulating immune responses in inflammation, indicating potential as a treatment for brain disorders.

This study found CK19/Bcl-2-positive and Bax-negative cells in hair follicle cultures from plucked hairs, supporting their potential identification as follicular stem cells located in the bulge area.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

The study found that melatonin treatment in early postnatal cashmere goats increased both the quantity and quality of cashmere by promoting secondary hair follicle development and enhancing antioxidant enzyme activities.

This study indicates that Fructus panax ginseng extract may promote hair growth by increasing proliferation in human hair dermal papilla cells and lengthening the anagen phase in mice.

This study found that liposterolic extracts of Serenoa repens enhanced hair regeneration and repair in DHT-induced hair loss mouse models, suggesting potential effects comparable to finasteride.

This study found that Polygonum multiflorum extract may promote hair growth by increasing anagen duration and activating dermal papilla cells in human hair follicles, as observed in cultured cell models.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

This study found that Rumex japonicus Houtt. root extract promoted hair growth by enhancing cell proliferation and preventing apoptosis in human dermal papilla cells and HaCaT cells, as well as in a mouse model.

This study found that apoptosis, along with proliferation, plays a crucial role in shaping and extending human hair follicles by coordinating the formation and differentiation of the hair canal.

This study found that S. scabiei infestation in rabbits leads to epidermal thickening possibly due to apoptosis-related proliferation and keratinization of the skin.

In a testosterone-induced mouse model of androgenetic alopecia, this study found that oral and topical administration of Connarus semidecandrus Jack ethanol extract promoted hair regrowth and improved hair health markers similar to finasteride, without detectable liver or kidney toxicity.

In this study, finasteride reduced oxidative stress, apoptosis, and inflammation in liver, kidney, and testis tissues of diabetic rats while boosting antioxidants, indicating potential protective effects that require further human trials for clinical application.

This study observed that different alkaline buffers had a significant impact on the volume of liquid consumed by fall armyworm larvae, emphasizing the importance of measuring imbibed volumes to reduce dose errors in bioassays.

This study found that the application of polyunsaturated fatty acids, particularly arachidonic acid, promoted hair growth and anagen induction in both human dermal papilla cells and mouse models.

This study found that sequential treatment with platelet-rich plasma injection followed by mesotherapy may promote hair growth in various alopecia cases, showing clinical improvement in hair count and thickness.

In this study, Caizhixuan hair tonic was found to promote hair growth in androgenetic alopecia mice by regulating the PI3K/Akt and apoptosis pathways.

This study found that topical application of TSG from Polygonum multiflorum promoted hair regrowth in depilated mice, potentially through the inhibition of apoptosis-related proteins.

This study found that topical formononetin treatment promoted hair regrowth in mice by normalizing hair follicle size and inhibiting apoptosis-related pathways.

In this study, Lespedeza bicolor extract was found to enhance dermal papilla cell proliferation and extend the anagen phase in mice, suggesting its potential as a treatment for alopecia.

In this study, hair follicle stem cell-derived exosomes enriched with miR-181a-5p accelerated hair regrowth and the transition from telogen to anagen in mice, with up to 90% hair coverage observed, suggesting enhanced activation of the Wnt/β-catenin pathway compared to controls.
