Human Keratinocytes Catabolize Thymidine

Journal of Investigative Dermatology, 1988
Human neonatal foreskin keratinocytes incorporate exogenous thymidine into DNA and proliferate in vitro even after reaching confluence. Keratinocytes also catabolize thymidine, as reported for the first time below.

Cultured Human Keratinocytes Express Tropoelastin

Journal of Investigative Dermatology, 1997
We detected elastin mRNA in cultured normal human keratinocytes by RNase protection assay. The content of elastin mRNA was estimated at approximately one-twentieth of that of cultured skin fibroblasts.

DNA Methylation and Differentiation of Human Keratinocytes

Journal of Investigative Dermatology, 1989
DNA methylation is a postreplicative modification thought to play a role in gene transcription in eucaryotes. Differences in the amount of 5-methylcytosine as a function of age and differentiation state have been reported [7, 14–18].

Bioelectric characterization of senescing human keratinocytes. [PDF]

iScience
Aging, a ubiquitous process that affects almost all multicellular organisms, is accompanied by the accumulation of senescent cells, leading to a decline of morphology and function. The ‘loss of morphostatic information’ theory posits that aging occurs due to gradual breakdown of order initially established during embryo development. Spatial differences

Transport of Biotin in Human Keratinocytes [PDF]

Journal of Investigative Dermatology, 2003
Biotin is an essential micronutrient for normal cellular function, growth, and development. Biotin deficiency leads to pathologic, dermatologic, and neurocutaneous manifestations in skin and its appendages. Previous studies described the presence of specific biotin transport systems in the epithelia of the intestine, liver, kidney, and placenta, and in

The Effect of Lipoaspirates on Human Keratinocytes [PDF]

Aesthetic Surgery Journal, 2016
One increasingly important trend in plastic, reconstructive, and aesthetic surgery is the use of fat grafts to improve cutaneous wound healing. In clinical practice, lipoaspirates (adipose tissue harvested by liposuction) are re-injected in a procedure called lipofilling.

Antioxidant Activities and Mechanisms of Tomentosin in Human Keratinocytes

Antioxidants, 2022
Tomentosin, one of natural sesquiterpene lactones sourced from Inula viscosa L., exerts therapeutic effects in various cell types. Here, we investigated the antioxidant activities and the underlying action mechanisms of tomentosin in HaCaT cells (a human

Chitin modulates innate immune responses of keratinocytes. [PDF]

, 2011
Chitin, after cellulose the second most abundant polysaccharide in nature, is an essential component of exoskeletons of crabs, shrimps and insects and protects these organisms from harsh conditions in their environment.

Human Keratinocyte Response to Superantigens

mSphere, 2020
Staphylococcus aureus and Streptococcus pyogenes are common human pathogens, causing infections that include the skin. Both pathogens produce a family of secreted toxins called superantigens, which have been shown to be important in human diseases.

In Vitro Cytotoxicity and Phototoxicity Assessment of Acylglutamate Surfactants Using a Human Keratinocyte Cell Line

Cosmetics, 2014
In the current study, human keratinocyte cell line was used as in vitro cell culture model to elucidate the effects of the fatty acid chain length of acylglutamate (amino acid-based surfactant) namely, sodium cocoyl glutamate, sodium lauroyl glutamate ...
