Our former research found that receptor interacting protein (RIP) 1 could be upregulated in human dermal fibroblasts(HDFs) after UVB irradiation by using two\u2010dimensional gel electrophoresis and matrix\u2010assisted laser desorption\/ionization time of flight mass spectrometry techniques. Besides, our further research found that RIP1 was involved in the UVB\u2010induced production of ROS and MMPs in HDFs. So far, the mechanisms of skin photodamage induced by UV mainly include DNA damage, oxidative stress, inflammation, apoptosis, and necroptosis. The NF\u2010\u03baB pathway can be activated eventually in the occurrence of inflammation and thus produce inflammatory cytokines such as IL\u20101, TNF\u2010\u03b1, IL\u20106, and IL\u20108. However, the mechanism by which the upregulation of RIP 1 induced by UVB contributes to photodamage is still unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims<\/jats:title>\n                    <jats:p>To explore the role of RIP1 in UVB\u2010induced skin inflammation and the related signal pathways and molecular mechanism, thus providing possible molecular markers for the diagnosis and prevention of skin photodamage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Human dermal fibroblasts were cultured in\u00a0vitro from normal human skin tissues. Besides, HaCaT cell lines and Balb\/c nude mice were also the research objects. First, cellular models of UVB\u2010induced upregulation of RIP1 were established. Then, the expression of RIP1 and localization of RIP1 before and after UVB irradiation of the cells were studied through western blot and immunofluorescence. Then, the change in the expression of the nuclear factor (NF)\u2010kappaB (NF\u2010\u03baB) pathway, along with RIP1 in these cells before and after UVB irradiation was detected, including NF\u2010\u03baB p50\/p65, p\u2010p65, I\u03baB and cytokines such as IL\u20101, IL\u20106, IL\u20108, and TNF\u2010\u03b1. Next, the effects of the RIP1 inhibitor Nec\u20101 and RIP1 siRNA on the expression of RIP1, p\u2010RIP1, NF\u2010\u03baB p50\/p65, inflammatory cytokines, and nuclear translocation of p\u2010p65 in\u00a0vitro cells after UVB irradiation were explored. At last, the expression of RIP1 and NF\u2010\u03baB pathway\u2010related proteins such as p65\/p50 was detected by western blot and immunohistochemistry before and after UVB radiation with or without subcutaneous injection of Nec\u20101 in the Balb\/c nude mice were detected.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>We provide that RIP1 involved in the photodamage of human dermal fibroblasts, HaCaT cell lines, and the skin tissues of Balb\/c nude mice induced by UVB. Upregulated RIP1 induced by UVB ultimately upregulates inflammatory cytokines, including IL\u20101, IL\u20106, IL\u20108, and TNF\u2010\u03b1 by triggering the expression of NF\u2010\u03baB p65\/p50 and activating nuclear translocation of p\u2010p65 in cells. RIP1 inhibitor Nec\u20101 or RIP1 siRNA can inhibit the function of RIP1. We first illustrate that the upregulated RIP1 induced by UVB contributes to photodamage of the skin via the NF\u2010\u03baB signaling pathway in\u00a0vivo and in\u00a0vitro.<\/jats:p>\n
