This study reports that the peptide GPIGS, found in Bacillus sp. M18 conditioned medium, may promote hair growth through the PI-3K/Akt pathway and accelerate hair regrowth in mice.

This study found that the penta-peptide Gly-Pro-Ile-Gly-Ser increased the proportion of thick hair and improved baldness appearance in Japanese men with androgenetic alopecia.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

Pigs are a good model for studying human hair growth and disorders.

This case report documents a 3-year-old guinea pig with hormonally active ovarian cysts, cystic endometrial hyperplasia, and bacterial endometritis associated with a uterine foreign body.

This research developed a pig graph pangenome assembly of 27 genomes, revealing the importance of structural variations in adaptation and breed-specific traits, with BTF3 identified as a key gene influencing intramuscular fat and meat quality.

This study found that guinea pig α-lactalbumin transgene was expressed in the mammary glands and sebaceous glands of transgenic mice, with milk protein production occurring in the expected secretory acini.

This study found that among Large White × Min pigs, 15 significant copy number variation regions were associated with villi hair traits, and identified candidate genes potentially linked to cold resistance, suggesting implications for breeding cold-resistant pigs.

The researchers reported that the SAGI PGP procedure resulted in excess weight loss of over 90% in the first year and normalized blood sugar levels without medication among diabetic patients by the first month post-operation.

This review discusses the roles of androgens in female mammals, focusing on how androgen receptor activity in pig reproductive organs may influence ovulation rate and litter size, but reports no new experimental results.

This study constructed a hair follicle-specific expression vector for IGFBP-5 in Inner Mongolia Cashmere goat cells, allowing for future functional genetic analyses and potential use in nuclear transfer.

This study describes the characteristics and potential research applications of the first hairless guinea pigs in Iran, noting their suitability for allergy, dermal, transplantation, and immunology studies.

This study found significant genetic differences between pigs with and without hair whorls, suggesting potential implications for pig breeding strategies in China.

In this study, Min pigs were found to have unique characteristics for secondary hair growth compared to Berkshire and Yorkshire pigs, with the Wnt and BMP signaling pathways stimulating follicle stem cell activity and promoting secondary hair growth and gene expression.

This research observed that hairless guinea pig dermal fibroblasts were more sensitive to a toxic exposure than human dermal fibroblasts, suggesting that guinea pigs might serve as an intermediate model for translating in vitro findings to whole organisms.

This review discusses potential causes and diagnostic tools for alopecia in guinea pigs and highlights the need to evaluate diet and housing, but it reports no original findings.

This study found that different diets had a negligible impact on guinea pigs' hair structure and did not significantly alter their health parameters, suggesting both tested diets met their nutritional needs without affecting their well-being.

This study found that weanling pigs fed a diet supplemented with 0.029% iron glycine chelate showed improved growth performance and better hair color compared to those receiving ferrous sulfide.

This study reported that knocking out the HR gene in pigs using CRISPR/Cas9 led to hairless eyelids and abnormalities in the thymus and peripheral blood, suggesting pigs as a model for human HR-related hair disorders.

Guinea pigs' skin issues in the lumbar area may be caused by dermatological problems and need proper care.

In this study, the researchers found distinct patterns of TGF-beta 1 and IGF-II expression in pig fetal subcutaneous tissue, suggesting specific regulatory roles in developing adipocytes and muscle tissue.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

This study reviews new treatments for androgenetic alopecia, including cell-derived exosomes and investigational drugs, which show potential to improve hair density and quality but require more rigorous and standardized trials to confirm efficacy and safety.

This study found that bone marrow mesenchymal stem cells from Guizhou miniature pigs showed stable growth and multidirectional differentiation potential, making them ideal for tissue engineering applications.

This review discusses the discovery and potential therapeutic uses of proteasome inhibitors across various diseases, including cancer and autoimmune conditions, but does not present new clinical data.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This review explores how sex differences influence the pathophysiology, incidence, and treatment outcomes of ischaemic heart disease, and emphasizes the need for more sex-specific research.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.
