Patterned hair loss (PHL) or androgenetic alopecia is a condition affecting about 50% of people worldwide. Several pharmacological medications have been developed over the years, but few studies have investigated their effectiveness. Therefore, new, safer and more effective strategies are required. Recent investigations showed that Annurca apple extract application could induce keratin production and promote hair growth thanks to the high amount of procyanidin B2 contained in. Hence, this study aimed to investigate the role of an Annurca apple extract in preventing PHL by testing it on human follicle dermal papilla cells (HFDPCs) for the first time. Treatment of HFDPCs with Annurca apple extract counteracted intracellular reactive oxygen species accumulation by increasing the activity of antioxidant enzymes such as superoxide dismutase 2 and catalase. Furthermore, treatment with Annurca apple extract increased β-catenin and fibroblast growth factor 2, which are involved in hair growth stimulation. These data suggest that Annurca apple extract may be a potential therapeutically useful nutraceutical product for preventing or treating hair loss by reducing oxidative stress and inducing the expression of hair growth-related factors.
模式性脱发(PHL)或雄激素性脱发是一种影响全球约 50%人群的疾病。多年来已经开发出几种药物治疗方法,但很少有研究调查它们的有效性。因此,需要新的、更安全和更有效的策略。最近的研究表明,安努卡苹果提取物的应用可以通过其所含的大量原花青素 B2 诱导角蛋白的产生和促进头发生长。因此,本研究首次旨在通过在人毛囊真皮乳头细胞(HFDPCs)上测试安努卡苹果提取物,来研究其在预防 PHL 中的作用。安努卡苹果提取物处理 HFDPCs 可通过增加超氧化物歧化酶 2 和过氧化氢酶等抗氧化酶的活性来对抗细胞内活性氧的积累。此外,安努卡苹果提取物处理增加了β-连环蛋白和纤维母细胞生长因子 2,它们参与刺激头发生长。这些数据表明,安努卡苹果提取物可能是一种有潜在治疗作用的营养保健品,可通过减少氧化应激和诱导与头发生长相关的因子表达来预防或治疗脱发。
