Blocking a protein called prostaglandin D2 might help treat hair loss.

This study identified 21 candidate genes linked to immunoglobulin levels in colostrum and serum of dairy cattle, suggesting potential for genetic selection to enhance immunity.

In this study, researchers successfully established a stable transgenic sheep fibroblast cell line containing an artificially synthesized spider dragline silk protein gene.

This study found that injecting PDGF-AA and -BB into mouse skin immediately triggered the hair growth cycle's anagen phase, suggesting potential treatment options for certain types of alopecia.

In this study, researchers overexpressed Lrig3 in mouse skin and observed hair loss linked to changes in skin protein profiles and signaling pathways, suggesting a potential role for Lrig3 in maintaining skin homeostasis.

This study concluded that cyproterone acetate alone produced antiandrogenic effects on the female gerbil prostate, while ethinyloestradiol alone stimulated estrogenic activity, and their combination led to prostatic lesions.

Among young rats, this study found that a liquid protein diet significantly affects body condition but has minimal impact on gingival collagen metabolism.

This study identified several genetic variants associated with cattle hair coat length, which may help breed more heat-tolerant animals by facilitating efficient heat loss.

In this study, mini rats with reduced growth hormone and insulin-like growth factor-1 levels exhibited distinct differences in skin thickness and hair cycle compared to standard Wistar rats, suggesting potential use as an animal model for studying GH deficiency-related skin conditions.

This study observed that low-dose intrauterine exposure to finasteride alters postnatal prostate development in male and female Mongolian gerbils, showing sex-specific differences in receptor expression and tissue changes.

In this study, a TGF-β mimic molecule from Heligmosomoides polygyrus was observed to enhance wound healing in mice, with improved tissue regeneration and specific immune cell recruitment without increased scarring.

This study found that the MsPG3-GFP fusion protein accumulates at the growing root hair tips in Medicago plants, suggesting its role in tip growth during symbiosis.

The study characterized the transcriptional changes in porcine SKP cells transitioning to fibroblast-like cells, indicating potential roles for specific signaling pathways in this cell fate transition.

This study found that the novel VG111 formulation alone healed canine wounds nearly twice as fast as the standard povidone–iodine treatment, achieving complete healing in 25 days compared to up to 50 days.

This study found that GS-KG9 and GS-E3D, bioactive ginseng extracts, reduced BBB disruption and neuronal apoptosis in the hippocampus of diabetic rats, suggesting potential therapeutic effects for diabetic patients.

This study reported that metallic-glass-coated tattoo needles reduced trauma and improved tattoo quality in pig skin experiments compared to uncoated needles.

This laboratory study found that PI extract, along with its metabolites Ang and Mac, inhibited cell proliferation and protein expression linked to pathways involved in BPH, suggesting potential for therapeutic use, although the Ang-Mac combination showed no significant effect on apoptosis through the p53 pathway.

This study found that extracts from Angelica gigas Nakai and Glycyrrhiza uralensis stimulated hair regrowth and follicle development in a shaving mouse model, suggesting potential for hair growth or hair loss prevention in humans.

This study developed and tested a new algorithm for analyzing coat and skin coloration in laboratory animals, using digital images and hierarchical color clustering, which effectively quantified color proportions and tracked changes over time without specialized software.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

This study found that while porcine skin resembles human skin, there are significant regional differences in skin composition and morphology, which could affect its use as a human analogue in research.

This study found that an acne complex animal model using rabbits showed more pronounced clinical symptoms and measured changes compared to the traditional Kligman model.

In this study, researchers found that ginsenoside Re from Panax ginseng increased hair shaft length and duration in mice, comparable to minoxidil, by modulating TGF-β signaling pathways.

This study found that ChatGPT 4.0 and Gemini 1.5 Flash provided more accurate and user-friendly responses to androgenetic alopecia questions than Deepseek R1, suggesting they could be effective tools for patient education with physician guidance.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

This study found that GPC1 plays a crucial role in regulating angiogenesis in human dermal microvascular endothelial cells, which may make it a potential target in alopecia treatment research.

LRIG1 protein affects hair growth by regulating skin receptors, leading to hair loss when overexpressed.

This study by Pérez-Oliva et al. explored how Mahogunin Ring Finger-1 (MGRN1) affects melanocortin-1 receptor (MC1R) signaling, suggesting that MGRN1 competitively inhibits Gαs binding to MC1R, influencing pigment production.
