Control of the skin scarring response Anais da ABC (AABC)
Ferreira,Lydia M.; Gragnani,Alfredo; Furtado,Fabianne; Hochman,Bernardo.
There comes a time when the understanding of the cutaneous healing process becomes essential due to the need for a precocious tissue repair to reduce the physical, social, and psychological morbidity. Advances in the knowledge on the control of interaction among cells, matrix and growth factors will provide more information on the Regenerative Medicine, an emerging area of research in medical bioengineering. However, considering the dynamism and complexity of the cutaneous healing response, it is fundamental to understand the control mechanism exerted by the interaction and synergism of both systems, cutaneous nervous and central nervous, via hypothalamus hypophysis-adrenal axis, a relevant subject, but hardly ever explored. The present study reviews the...

Immunolocalization of HB-EGF in Human Skin by Streptavidin-Peroxidase (HRP) Conjugate Method International Journal of Morphology
Castrogiovanni,P; Mazzone,V; Imbesi,R.
EGF family growth factors consists of growth factors, such as transforming growth factor (TGF)-a, heparin-binding EGF-like growth factor (HB-EGF), amphiregulin (AR) and epiregulin, autocrine growth factors in normal human keratinocytes. HB-EGF is mitogen for epithelial cells and like other members of the EGF family, HB-EGF exerts its biological effects via interaction with the EGF receptor (EGFR). HB-EGF is an autocrine growth factor for human keratinocytes, and has a possible role as a paracrine growth factor for fibroblast. Our report concerning immunohistochemical localization of HB-EGF in normal skin by using the streptavidin-peroxidase (HRP) conjugate method, confirms previous data, revealing specific patterns of HB-EGF localization. Identification of...

Long non-coding RNA HOTAIR promotes UVB-induced apoptosis and inflammatory injury by up-regulation of PKR in keratinocytes BJMBR
Liu,Guo; Zhang,Wenhao.
Excessive exposure to ultraviolet (UV) rays can cause damage of the skin and may induce cancer, immunosuppression, photoaging, and inflammation. The long non-coding RNA (lncRNA) HOX antisense intergenic RNA (HOTAIR) is involved in multiple human biological processes. However, its role in UVB-induced keratinocyte injury is unclear. This study was performed to investigate the effects of HOTAIR in UVB-induced apoptosis and inflammatory injury in human keratinocytes (HaCaT cells). Quantitative real-time polymerase chain reaction was performed to analyze the expression levels of HOTAIR, PKR, TNF-α, and IL-6. Cell viability was measured using trypan blue exclusion method and cell apoptosis using flow cytometry and western blot. ELISA was used to measure the...

Protective effect of silk lutein on ultraviolet B-irradiated human keratinocytes Biol. Res.
Pongcharoen,Sutatip; Warnnissorn,Prateep; Lertkajornsin,Ongart; Limpeanchob,Nanteetip; Sutheerawattananonda,Manote.
Carotenoids are efficient antioxidants that are of great importance for human health. Lutein and zeaxanthin are carotinoids present in high concentrations in the human retina which are involved in the photoprotection of the human eye. Lutein may also protect the skin from ultraviolet (UV)-induced damage. The present study investigated the protective effect of lutein extracted from yellow silk cocoons of Bombyx mori on human keratinocytes against UVB irradiation. A human keratinocyte cell line and primary human keratinocytes were used to investigate the UVB protection effects of silk lutein and plant lutein. Silk lutein showed no cytotoxicity to keratinocytes. Treatment with silk lutein prior to UVB irradiation enhanced cell viability and cell...
