This chapter emphasizes the critical role of the integumentary system in animal physiology, detailing its structures, immune functions, and sensory capabilities as crucial for homeostasis, protection, and various physiological processes.

In this study, researchers found that finasteride induces dysregulation of genes related to neuropsychiatric disorders, including the HOMER-3 gene associated with dementia, and propose exploring craniosacral osteopathic therapy's potential to modulate this gene's methylation profile and alleviate related symptoms.

This study found that elevated luteinizing hormone levels were significantly associated with female pattern hair loss, and implicated LH/LHR signaling in the aging and damage of hair follicles.

This study highlights recent biological and technological strategies in anti-aging research aimed at delaying aging and related diseases, improving skin healing, and potentially restoring hair growth.

The study found that sonication washing of hair roots with fewer than 50 visible nuclei could reduce the number of nuclei available for DNA extraction and STR typing, suggesting that for laboratories focused on nuDNA analysis, a gentler washing method might be adequate.

This study discusses the potential health risks associated with occupational radiation exposure, including genetic mutations, cancers, and other diseases, and outlines strategies for prevention and occupational health safety.

In this review, researchers discuss the role of epigenetic modifications in epidermal stem cells' decline during skin aging and identify potential interventions targeting these disruptions, suggesting significant possibilities for antiaging strategies and dermatological treatments.

This study found that inhibiting the ATR kinase with VE-822 impairs DNA repair capability in quiescent human keratinocytes exposed to solar-simulated UV radiation, suggesting ATR's critical role in facilitating effective DNA damage repair and cellular recovery under UV stress conditions.

Aptamers can improve wound healing and promote hair growth.

Paclitaxel chemotherapy causes premature aging and damage to hair follicles, potentially leading to permanent hair loss.

In this study, researchers observed that Finasteride improved cardiac function by enhancing antioxidant levels and reducing oxidative stress in obese and aging rats, though it did not benefit metabolic status and induced insulin resistance in normal diet-fed rats.

Taxane chemotherapy can cause permanent hair loss by damaging hair follicles and altering their DNA.

This study suggests that topical minoxidil could promote hair regrowth in individuals with alopecia areata by exerting a localized immunosuppressive effect, and that combining minoxidil with other treatments may enhance hair growth outcomes.

This study found that spaceflight may induce skin health risks in astronauts by causing DNA damage and mitochondrial dysregulation, while also identifying gene expression changes that help re-adaptation after returning to Earth.

This study investigated genetic and epigenetic markers for prostate cancer, reporting that certain genotype combinations may influence cancer risk or protection and identifying GSTP1 promoter methylation as a strong prognostic and diagnostic marker linked to tumor aggressiveness.

This review summarizes recent findings on the role of mesenchymal stem cell-derived exosomal microRNAs in skin regeneration and rejuvenation, discussing their potential for treating skin damage and aging, and exploring bioengineering methods to enhance therapeutic effects.

This study suggests that abnormal levels of zinc, copper, and iron in serum or hair may serve as auxiliary and prognostic tests for various skin diseases, though further research is necessary due to conflicting data.

This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.

This study found that DNA methylation-based age predictors and lifestyle factors significantly affect perceived age and external visible characteristics in the aging process, with implications for forensic and anti-aging cosmetic applications.

In this study, the deletion of NIPP1 in keratinocytes led to chronic skin inflammation and epidermal changes in mice, with early cell-cycle arrest and premature senescence observed, potentially contributing to reduced mutagen sensitivity.

This review discusses recent insights into the dynamics and regulation of the epidermal differentiation complex during keratinocyte differentiation and reports no new experimental results.

This study reports that treating a feline with progressive pruritus, alopecia, and FIV infection with imidacloprid and moxidectin resulted in remission of clinical signs and elimination of Demodex cati mites, as confirmed by parasitological examination and genetic sequencing.

Minoxidil is an effective and safe treatment for common hair loss when applied to the skin, but more research is needed for optimal use.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This source highlights that arsenic exposure through contaminated groundwater is a significant global health risk, leading to skin and hair conditions such as pigmentation changes, skin irritation, alopecia, and can eventually result in skin cancer.

This source reviews mechanisms and existing treatments for hair aging, highlighting factors like oxidative stress and DNA repair defects that affect hair follicle and stem cell function, and discusses research limitations and future directions in the field.

In this study, DNA analysis of patients with androgenetic alopecia and alopecia areata indicated potential differences in treatment response based on genetic makeup across Romanian and Brazilian populations, notably involving genes like GR-alpha and SULT1A1, which may guide personalized treatment strategies.

This review highlights recent advancements in prostate cancer treatments, particularly new drugs targeting signaling pathways and showing promise in clinical trials, but notes the high recurrence rate of castration-resistant cancer post-therapy, requiring ongoing efforts for effective solutions.

This study evaluated genetic differences in hair loss patients from Romania and Brazil, finding that specific gene variations were more common in Brazilian patients. The researchers suggest certain drugs may be more effective based on these genetic markers, but most genes showed no population differences.

In this study, researchers observed that heat stress significantly affected hair and skin traits in two indigenous goat breeds, with Kodi Aadu goats demonstrating greater thermal resilience compared to Kanni Aadu goats, potentially due to differences in gene expression and methylation.
