概括

一种新的葡萄种子提取物 (GSE) 富含普罗基亚尼丁C1 (PCC1),称为NSPCC1,可以对抗皮肤衰老. 它通过增强抗氧化防御和调节关键细胞通路来保护抗紫外线和内在衰老.

科学领域:

皮肤病学和衰老研究研究
自然产品化学自然产品化学
分子生物学分子生物学

背景情况:

皮肤衰老的结果来自外部 (例如,紫外线暴露) 和内在因素 (氧化应激,炎症,糖化).
植物衍生化合物,如葡萄提取物 (GSE),由于抗氧化和抗炎性质,显示出抗衰老护肤的潜力.
素C1 (PCC1),GSE的一个组成部分,已在小鼠中表现出老化活性和寿命延长.

研究的目的:

在小鼠模型中评估一种新型PCC1-丰富的GSE (NSPCC1) 对抗UV和d-银糖诱导的皮肤衰老.
研究NSPCC1抗衰老作用的潜在分子机制.
评估NSPCC1对皮肤结构,水分,弹性和抗氧化能力的影响.

主要方法:

用小鼠模型通过紫外线辐射和d-银糖诱导皮肤衰老.
小鼠补充了NSPCC1,并分析了皮肤和血清.
测量的主要结果包括皮肤细胞死亡,原水平,皮肤弹性,水分和抗氧化剂标记.
用RNA测序来分析对NSPCC1.1的反应中的基因表达变化.

主要成果:

补充NSPCC1显著减少皮肤细胞死亡,原降解和结构缩.
它部分恢复了皮肤弹性和水分,同时增强了血清和组织的抗氧化防御.
RNA测序表明NSPCC1调节MAPK和AMPK通路,抵消与年龄相关的失调.

结论:

NSPCC1在缓解外在和内在皮肤衰老过程方面显示出显著的潜力.
这种新的GSE配方为先进的护肤干预提供了一个有希望的自然策略.
对NSPCC1机制的进一步研究可能会导致新的抗衰老疗法.

MAPK Signaling Cascades

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
