How does radiation affect skin?

Radiation modulates skin lipid metabolism by downregulating multiple pathways. It also reduces the amount of skin fat and variations in lipid metabolism. Mature adipocytes promote the migration of co-cultured keratinocytes and fibroblasts, but do not promote their proliferation. Fatty acid–binding protein 4 can be incorporated into skin cells and promote the repair of DNA damage in irradiated skin fibroblasts. Radiation induces skin lipid remodeling, and skin fat cells have protective effects on radiation-induced skin damage [24]. Radiation-induced skin damage is depicted by a chronic inflammatory state and an increase in ROS synthesis. Ionizing radiation facilitates the synthesis of reactive nitrogen and oxygen species (RNS/ROS) for the radiolysis of water [25]. The mentioned reaction can induce oxidative damage and cytotoxicity, thereby causing acute or chronic skin damage. The use of antioxidants can reduce the damage attributed to radiation [26]. For instance, superoxide dismutase and its mimetics reduce ROS levels and RSI. Rare is known regarding the underlying mechanisms by which radiation generates and amplifies ROS. Nitric oxide (NO) is critical to the homeostasis of the functioning of the skin and has become the target of treatment for specific skin diseases [27]. In mammals, NO is synthesized by L-arginine, NADPH, as well as NO synthase (NOS) in oxygen. NOS isoforms are identified in the skin, and 5,6,7,8-tetrahydrobiopterin (BH4) acts as an important cofactor for NOS [28]. ROS synthesis may hinder the use of BH4 for the oxidation of BH4 to dihydrobiopterin (BH2). Accordingly, uncoupling of NOS may be caused, and the synthesis of oxidative superoxide radicals can be facilitated [29]. The inhibition of GCH1 in vivoincreases oxidative stress and down-regulates the white blood cell count after radiation [30]. Radiation destroys BH4, thereby enhancing the ROS cascade response. GCH1 revives BH4 levels and ROS synthesis [31].

Does radiation affect angiogenic factors?

Radiation can also cause a reduction in the expression levels of angiogenic factors. It up-regulates the expression levels of proinflammatory cytokines IL-1, IFN-γ, TNF-α, and IL-6, prevents collagen deposition, and induces TGF-beta1 expression by macrophage/stromal cell activation. Elevated levels of TGF-beta1 break down collagen and stimulate microvascular variations [8]. Neovascularization requires signaling through the vascular endothelial growth factor (VEGF) family [35]. VEGF refers to a marker of neovascularization. After exposure to 10 Gy irradiation, the synthesis of angiogenic factor VEGF in the blood of rat tumor carriers was significantly hindered [36]. Low levels of VEGF after radiotherapy indicated that targeted VEGF treatment enhanced vascular repair. Preclinical studies supported this by showing that irradiated rat bladder administrated with VEGF resulted in a marked reduction in fibrotic tissue and enhanced tissue angiogenesis [37]. PlGF refers to a member of the VEGF family and is involved primarily in pathological angiogenesis, including cancer. PlGF helps in wound healing by provoking blood vessel formation, macrophage recruitment, keratinocyte migration, and formation of granular tissue [38]. bFGF is an angiogenic growth factor with the ability to induce endothelial cell proliferation and migration. It is capable of expediting the healing of second-degree burn wounds and improving scar quality [39]. In burns, dermal components are required for surface resurfacing, and bFGF enhances wound healing and elevates the number of skin-derived mesenchymal stem cells in a dose-dependent manner under serum-free conditions [40]. In surgery, bFGF is immediately used for skin grafts and artificial dermal reconstruction after debridement [41]. Early use in local tissue may effectively protect radiation-damaged cells from cell death [42].

Does ionizing radiation cause cell depletion?

Ionizing radiation is capable of affecting G2- and M-phase cells in the cell cycle, thereby causing apoptosis and impaired cell proliferation and migration; as a result, an overall cell depletion is caused . Ionizing radiation can damage collagen structures. Cell proliferation is suppressed in irradiated wounds.
