Summary
The transcription factor ZNF750 is crucial for skin barrier function. Its disruption impairs epidermal differentiation and barrier formation, offering insights into skin disease pathogenesis.
Area of Science:
- Dermatology
- Molecular Biology
- Genetics
Background:
- The epidermis forms a vital protective barrier through differentiated keratinocytes.
- Disruptions in epidermal differentiation are linked to various skin disorders.
- ZNF750 is an epithelial transcription factor critical for keratinocyte differentiation in vitro.
Purpose of the Study:
- To investigate the role of ZNF750 in epidermal development and barrier function in vivo.
- To understand the molecular mechanisms underlying ZNF750-related skin diseases.
Main Methods:
- Utilized an epidermal-specific Znf750 conditional knockout mouse model.
- Performed molecular dissection and gene expression analysis.
- Examined epidermal ultrastructure and barrier function.
Main Results:
- Znf750 deletion impaired epidermal barrier function and caused perinatal lethality.
- Ultrastructural defects were observed in differentiated epidermal layers.
- Expression of ZNF750-dependent genes involved in cornified envelope formation and lipid processing was altered.
Conclusions:
- ZNF750 plays a significant role in epidermal development and barrier formation in vivo.
- Compensatory mechanisms exist in vivo despite Znf750 deletion.
- Findings link ZNF750 to specific epidermal differentiation genes implicated in human skin barrier diseases.

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:21Layers of the Epidermis
4.2K
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

01:12Renewal of Skin Epidermal Stem Cells
2.5K
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...

The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

01:21Accessory Structures of the Skin: Sebaceous Glands
2.0K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
