概括

在小鼠中,素77 (KRT77) 缺乏并没有损害皮肤发育. 然而,它的缺失导致了氨酸1 (KRT1) 的表达增加,这表明KRT1补偿了KRT77在皮肤平衡中的损失.

科学领域:

皮肤病学皮肤病学
分子生物学分子生物学
遗传学遗传学是一个

背景情况:

质蛋白是维护表皮结构完整性的关键中间丝蛋白.
质蛋白基因的突变导致遗传性皮肤疾病,异常质蛋白表达与皮肤疾病有关.
氨酸77 (KRT77) 是一种II型氨酸,在汗腺管道中表达,其特定的皮肤功能基本上是未知的.

研究的目的:

为了研究素77 (KRT77) 在皮肤生物学和平衡的功能.
使用CRISPR/Cas9技术生成和分析Krt77-缺陷 (Krt77-KO) 的小鼠模型.

主要方法:

通过CRISPR/Cas9基因编辑生成一个Krt77-缺乏的 (Krt77-KO) 鼠标系.
对Krt77-KO小鼠皮肤和尾发育的分析.
定量实时PCR (RT-qPCR) 用于测量KRT1.1的mRNA水平.
西部斑点分析以评估KRT1.1的蛋白质水平.

主要成果:

Krt77-KO小鼠没有表现出胎儿死亡率或皮肤和附属部分的发育缺陷.
与对照组相比,Krt77-KO小鼠的皮肤中观察到mRNA和蛋白质水平的Keratin 1 (KRT1) 显著增加.
与KRT77同一个亚家族中的另一种II型质蛋白KRT1显示出补偿性上调.

结论:

在小鼠皮肤中缺少KRT77导致KRT1.1的上调.
KRT1似乎弥补了KRT77的缺失,突出了表皮平衡中的潜在救援机制.
这项研究阐明了KRT77在皮肤生物学中的新角色,并确定了与KRT1.1的补偿关系.

关键词:

皮肤表皮的表皮.在KRT1中,KRT1是KRT1.在KRT10上使用KRT10.在 KRT7777 里面.淘汰赛鼠标模型模型

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...

Cytoskeletal Linker Proteins - Plakins

Cytoskeletal Linker Proteins - Plakins

Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...
