Atopic Dermatitis (AD) is a widespread skin disorder, affecting some 20% of the world’s population. Though the precise molecular underpinnings are still being understood, changes in lipid composition within the epidermal stratum corneum (SC) layer have been shown to be closely linked with AD. Previous studies have identified several specific...
BCL11B, also known as CTIP2, is a transcription factor which plays a critical role in the regulation and development of many tissues and organ systems, including the skin. A 2019 study by Goos et. al. uncovered a novel point mutation in BCL11B gene that converted the Arginine(R)-3 residue to a...
Skin is the largest organ in the body that protects the organism from environmental, chemical and physical traumas of each passing day. The protective skin epidermal permeability barrier (EPB) is formed within the exterior layers of the epidermis, which are regularly sloughed off and repopulated by movement of inner cells....
Cutaneous melanoma remains the deadliest form of skin cancer, with a
diagnosis of metastasis indicating a median survival rate of less than a year. Solar ultraviolet (UV) radiation, especially childhood sun exposure, is an important etiological risk factor of melanoma. Previous studies determined that mice selectively lacking the nuclear hormone...
Cutaneous melanoma remains the deadliest form of skin cancer arising from malignant transformation of pigment-producing melanocytes, with a diagnosis of metastasis indicating a median survival rate of less than a year. Solar ultraviolet (UV) radiation, especially childhood sun exposure, is an important etiological risk factor of melanoma. This DNA damage...
Mammalian skin is the largest organ of the body and serves as a barrier to protect the body against chemical, mechanical and pathogenic insults as well as water loss. The epidermis is formed from the primitive ectoderm into a multilayered stratified epithelium, consisting of basal, spinous, granular and outermost cornified...
The BRAF proto-oncogene is a member of the Raf protein family that encodes serine/threonine protein kinases, which activate the MEK/ERK signaling transduction pathway. The V600E mutation of BRAF, found in 70% of melanoma cases, causes an upregulation of MEK/ERK signaling which leads to many hallmarks of cancer, including apoptosis evasion,...
Dermatological issues are a widespread problem in humans that are often
overlooked. In our present study, we have isolated lipids from de-identified epidermal
skin tape samples from both Atopic Dermatitis and healthy individuals using a high
efficiency one-step extraction method, which were subsequently analyzed using modified
Liquid chromatography–mass spectrometry (LC-MS)....
Melanocytes are dendritic, pigment-producing cells located in the skin and are responsible for its protection against the deleterious effects of solar ultraviolet radiation (UVR), which include DNA damage and elevated reactive oxygen species (ROS). They do so by synthesizing photoprotective melanin pigments and distributing them to adjacent skin cells (e.g.,...
Melanoma is the deadliest form of skin cancer, arising from malignant transformation of pigment-producing melanocytes. The primary risk factor for melanoma and other skin cancers is DNA damage resulting from unprotected solar ultraviolet radiation (UVR). If incorrectly repaired, this damage can result in incorporation of mutations that cause aberrant cell...
